refactor(store): entities into real tables, with the constraints in the schema - #1322
Merged
Conversation
Sixteen tables for the seven entities, replacing JSON blobs in `kv`. Two conventions the old layout could not express: A primary key is an id, never something the user typed. Snippets were keyed by name and private keys by a name-used-as-id, so renaming either broke every reference — `Spi.ssh.keyId` pointed at a private key's *name*. Names are ordinary `UNIQUE` columns now and a rename is one `UPDATE`. A list or map field is a child table. `server_tag`, `server_env`, `server_jump`, `server_disabled_cmd`, `server_custom_cmd`, `snippet_tag`, `snippet_auto_run_on`, and `known_host` — which was a JSON map in `setting` keyed `<serverId>::<keyType>`, so a deleted server left its fingerprints behind for ever. Rules that lived in one call site now live in the schema. SSH-or-monitor exclusivity was `Spix.validate()` alone, so a record could be written with both and fail later at connect time; it is a CHECK. Orphan cleanup was six hand-written calls in `delServer` that missed four more (agent conversations, port forwards, container hosts, known hosts); it is ON DELETE CASCADE. Deleting a private key sets its servers' key to null rather than deleting them. `setting` and `history` stay in `kv`: 103 unrelated preferences with no relations and nothing that queries by field, where a new one should stay a one-line change rather than a migration. `agent_conversation.data` stays JSON — an ordered log of heterogeneous items, only ever read whole. Columns would buy nothing and cost a migration per new item kind. Nothing writes to these yet; the stores and the m004 migration come next.
Sync uploads the whole backup every time, so the cost grows with the data rather than with the change. Fixing that needs per-row change tracking, and adding it after the m004 migration has run would be a second migration — so the columns go in before anything writes to these tables. `updated_at` is what an incremental pull selects on; `rev` separates two edits inside one millisecond, which a clock cannot. Both live on the six sync roots only. A server and its tags, envs and jump hosts are one logical record: the children cascade with the parent and have no meaning without it, so syncing them separately would let a tag arrive before its server. `tombstone` makes a deletion a fact that can travel. Without one the peer that still holds the row reads its absence as an addition and puts it back, which is how a deleted server returns on the next sync. `sync_state` holds this device's id and its per-peer watermarks, and is never itself uploaded. The remote is a whole-file interface — `upload`/`download`/`list`, no range requests, no ETag — so the protocol on top of this has to be an immutable base plus append-only change files, named per device and sequence, with the peers pulling only what they have not seen. That comes next; this is what it will read.
One transaction: a migration that stops half way leaves the records in two shapes with nothing to say which is authoritative. Snippets and private keys get real ids. Both were keyed by a name the user typed — a private key's `id` *was* its name — so `Spi.ssh.keyId` pointed at a name and renaming a key detached every server using it. The old ids are mapped to generated ones and the references rewritten as they are copied. Rows that point at nothing are dropped rather than carried: `conn_stat` has a foreign key now, and the hand-written cleanup in `delServer` missed cases, so an upgrading install holds statistics for servers deleted long ago. Same for a jump host, a port forward or an auto-run target naming a server that no longer exists. Each is logged. A server that could be reached neither way, or both, cannot be represented under the new CHECK. It could not be connected to before either — `genClient` had nothing to dial — so it is dropped with a warning rather than failing the migration for every other record. `updated_at` is carried across instead of stamped as now, so the first sync after upgrading does not read as "everything changed today". `conn_stat`, `agent_conversation` and `agent_active` already exist under those names and `createAll` is `IF NOT EXISTS`, so they are renamed aside, recreated and copied through. Also fixes the ordering this exposed. `HiveImport` recorded `current`, which after adding v5 meant an upgrading install was marked done while its records sat in the v4 kv shape — `migrate` would have skipped m004 and stranded them. It now records `hiveImportProduces`, the layout it actually writes, and the two tests that asserted otherwise say so.
The SQLite layout has not shipped, so every install in the field is on Hive and 1466, 1480 and 1491 are all upgrade sources. The suite ran against one. `hive_adapters.g.dart` is byte-identical across the three, so they share one set of assertions — but that is a fact worth checking rather than assuming, so 1480 gets a fixture generated from its own tag even though the generator ran against it unchanged. 1491 shipped an `agent_conversation` box the others do not have, which is the case that needed its own data. The test is now parameterised over the three. `Paths.doc` is `late final` and cannot be set per group, so one temp directory is refilled from the fixture under test in `setUp`. Building the 1491 conversations by hand first is what caught the reason these fixtures exist: written as JSON with camelCase keys and a `type` discriminator they were silently dropped on import, because the release writes snake_case and `kind`. They are built through 1491's own model and serialiser now, and the README says why.
Deliberately not a `KvStore`: there is no key-addressed `get`/`set` here, because the records have columns, relations and constraints now. What it keeps is the shape the app already talks to — `fetch`, `fetchOneRaw`, `put`, `delete`, `watch` — so the call sites go on passing models around without learning which storage backs them, and this change stays in the storage layer instead of spreading through the app. `deleteById` is one statement: every child table declares ON DELETE CASCADE, replacing the six hand-written cleanups in `delServer` and the four it missed. It writes a tombstone as it goes, because a peer that still holds the row reads its absence as an addition and puts it back. `put` stamps `updated_at` and increments `rev` in the same transaction as the write, and `touch` does it for a parent whose child rows changed — an edit to a tag is a change to the server that owns it. Both clear any tombstone for the id: a record that comes back has stopped being deleted.
A Spi is six tables now, read with six statements total rather than six per server: each child table is read once and grouped in Dart. `upsert` exists because the test caught `INSERT OR REPLACE` resetting `rev` to its default on every write — that statement deletes the row and inserts a new one, so every column absent from it goes back to the default, and `rev` is the one column that must not. It is an `ON CONFLICT DO UPDATE` naming only the data columns, leaving `updated_at` and `rev` to `_stamp`. Child rows are replaced wholesale rather than diffed: the record arrives as one object, so what it no longer carries is what was removed. A jump host that no longer exists is dropped instead of written as a dangling reference, which the old JSON array could hold and this cannot. Tags come back as a set rather than in the order the JSON array kept: the child table has no ordering column and the UI filters by membership. Noted in the test rather than left to be discovered. `idsWithTag` and `allTags` are what the server list used to get by decoding every record.
The storage layer is hand-written SQL strings and hand-written row mapping, which is what an ORM generates. `INSERT OR REPLACE` silently resetting `rev` — caught by a test, not by the compiler — is the kind of thing typed queries prevent. Verified before committing to it, because encryption is the constraint that would have ruled it out: `NativeDatabase.opened` takes the `sqlite3` `Database` this app opens and keys itself, so sqlite3mc and the build-hook bundling are untouched. A spike confirmed the SSH-xor-monitor CHECK still fires and a dangling foreign key is still refused through Drift's executor — `foreign_keys` is per-connection, so that also confirms Drift is on the same connection rather than opening its own. drift_dev is pinned to 2.34.0 rather than 2.34.5: `hive_ce_generator` wants analyzer ^12 and 2.34.1+ wants ^13. That generator only exists to rebuild the frozen Hive adapters `HiveImport` reads, so it goes when that does.
The 18 tables are Drift table definitions now, and `tables_schema_test.dart` was the acceptance gate: all 17 guarantees pass against what Drift creates — the SSH-xor-monitor CHECK, the cascades, ON DELETE SET NULL for a deleted private key, the unique names, the sync columns, the tag queries. With that shown, the hand-written DDL is a second source for one schema and is gone; `Tables` keeps only the name lists. `schemaVersion` is 1 and stays there. Version stays with `SchemaVersion`, because the steps that matter are outside what a Drift migration can express: m003 reads Hive boxes, m004 remaps ids and rewrites the references between them. Two mechanisms advancing one number is the ambiguity this change exists to remove. Drift cannot reference a column inside its own `check()`, which the analyzer caught as a recursive getter three times; those are table constraints instead. m003 no longer writes through the store objects. It produces the v4 key-value shape and those stores have moved on to tables — a migration that calls today's code changes meaning every time that code does. It writes into `kv` directly, with `updated_at` 0 so m004 can carry the real timestamps forward and the first sync after upgrading does not read as "everything changed". drift_dev is 2.34.0: `hive_ce_generator` wants analyzer ^12 and 2.34.1+ wants ^13. That generator goes when `HiveImport` does. The tree does not compile past the store layer yet — the six remaining stores and their call sites are the next step.
Every store that holds records now reads and writes columns rather than a JSON blob in `kv`: private keys, snippets, port forwards and the container settings join the servers that moved first. Three things that were data loss, found while porting: - A private key's id *was* its name, and a snippet's key was its name. Both are generated ids with the name as an ordinary unique column now, so a rename is an UPDATE rather than a delete and an insert that leaves every reference behind. - m004 mapped `ssh.keyId` through the old-id table and wrote null when it matched nothing — which is exactly what an `IdentityFile` path put there by the ssh-config import looks like. It lands in `ssh_key_path` now, which is what `ServerStore.migrateIdentityFilePaths` used to recover it into. - The `docker` store's bare `<serverId>` keys, the Docker host from before per-runtime hosts, were dropped along with `providerConfig`. Both are carried across. `migrateIds` and `migrateIdentityFilePaths` are gone from the launch path. They scanned every server on every launch to repair a shape only an upgrading install can hold, and neither could have run after m004 anyway: an empty `Spi.id` has nowhere to live once the id is a primary key. m003 now writes one shape — rows in `kv` — instead of three. It no longer reaches through today's store objects for connection stats and agent conversations, so m004 owns every table and the rename-aside dance goes with it. The schema is created when the database is opened, which is what lets m004 stay one synchronous transaction. Also: container hosts and the chosen runtime are children of `server` rather than records of their own, so they cascade and travel with it; port forwards are in the backup for the first time; `conn_stat` rows get generated ids, so two attempts in the same millisecond no longer collide. The tests do not compile yet.
`hive_release_migration_test` now runs HiveImport *and* KvToTablesMigration against each release fixture, so what it asserts is the shape the app reads rather than an intermediate no build ships. 42 assertions across 1466/1480/ 1491; it found five real bugs on the first run: - The generated Hive adapters no longer read any released box. Adding `id` to `Snippet` and `name` to `PrivateKeyInfo` made the generator emit `fields[n] as String` for a field those bytes do not carry, so both boxes failed to open and every snippet and key was silently left behind. They are frozen types in `lib/hive/legacy_adapters.dart` now, like `LegacySpiV2` already was, and out of `@GenerateAdapters`. - m004 read `ssh['keyId']`, but `SshCredential.toJson` writes `pubKeyId` — kept from the flat pre-v3 layout. Every server lost its key. - It read `key['key']`, but the released `PrivateKeyInfo.toJson` writes `private_key`. Every key was dropped. - It read `conversation['serverId']`, but `AgentConversation.toJson` is hand-written and snake_case. Every conversation was dropped. - `_toSpi` built a `ServerCustom` unconditionally, since the columns are NOT NULL with defaults, giving every server a non-null `custom` it never had. `hive_import_test` keeps its own scope — retry, idempotency, per-box progress — and asserts against `kv`, which is all the import produces now. It seeds through the released layouts rather than today's models. Two behaviour changes the tests pin down: deleting an agent conversation now cascades to the active row, so which one was active is read before the delete; and two connection attempts in the same millisecond are two rows, which is what generated ids were for. 1036/1036 tests pass.
A rename is an UPDATE of one column now, so the providers stop deleting and reinserting: that wrote a tombstone for a record that is still there and took its tags and auto-run targets with it by cascade. Renaming a snippet tag is one statement over `snippet_tag` rather than rewriting every snippet holding it, and the second copy of that loop in the provider is gone. Names are unique in the schema rather than in whichever dialog last checked, so a collision surfaces as `DuplicateNameException` and both editors turn it into a message and stay open on the field the user has to change. One new string, `nameAlreadyExistsFmt`, in en and zh.
`docs/development/architecture.md` still described hive_ce in both locales. Replaced with what is there: one encrypted SQLite file, two shapes in it and the rule for choosing between them, Drift owning the DDL and nothing else, ids that are not names, children that travel with their parent, and the two migration steps. CLAUDE.md gets the parts that steer future work — `INSERT OR REPLACE` being wrong on any row with sync columns or children, and that changing a model `lib/hive/` still has a generated adapter for makes every box written before it unreadable.
The submodule pointer was a local commit based on fl_lib before #40, which made `clear` asynchronous and `SyncIface` non-const. Rebasing onto main brings both: - `BakSyncer` stops being a const singleton, since `SyncIface` no longer has a const constructor. - Three `store.clear()` calls did not await, so the settings page reported success before anything was cleared and two tests asserted on a store that had not been cleared yet. - `CachedSqliteStore` is deleted. Every store that extended it — server, private key, snippet — owns a table now, so it had no subclasses left. Blocked on lollipopkit/fl_lib#42; CI here cannot resolve the submodule until that lands.

#1318 hardened the stores, authentication and background concurrency while this branch was open, and it touched the same files. Kept from main: the async provider mutations with the store write before the state update, the `clear all settings` guard that checks the result, and its error handling. Kept from here: id-based record matching, one write per rename instead of a delete and an insert, and the tag rename as a single UPDATE. `lib/data/store/cached_store.dart` is deleted rather than merged: every store that extended it owns a table now, so it has no subclasses left.

Restore ordering, two silent losses, and a generated id shown to the user. - **A jump host is a server**, so during a restore the row it names may be written later. `write` inserted the link inline and dropped any forward reference; `writeLinks` is a second pass `replaceAll` and `merge` run once every row exists. - **The key picker rendered `item.id`.** With ids generated, that chip showed the user a `ShortId` instead of the name they typed. - **`_toEncodable` did not know `PortForwardConfig`**, so a backup carrying a typed one threw. Covered by a round trip through `fromJsonString`. - **`merge` stamped `updated_at = 0`** for a record the backup carried no timestamp for, leaving it older than anything — the next sync would take it straight back out. Absent means now. - **m004 collapsed duplicate snippet names.** Two snippets sharing a stored name produced two records but one `renamed` entry, so both `snippetOrder` entries resolved to whichever was de-duplicated last. - `SnippetNotifier.update` refuses a changed id, which `EntityStore.update` already did and going straight to `put` bypassed. - Deleting an agent conversation and promoting its replacement are one transaction: the delete cascades the active row away. - `resetTables()` for a caller that closes the handle itself, and the previous `AppDb.close` is best-effort. - The private key editor only touches `_loading` while mounted — `decryptPem` runs on another isolate. - Docs, the fixture README's destination path, an assertion no byte could satisfy, two unused temp dirs, and a key fixture whose id and name differ. Not taken: fl_lib's `set`/`setAll`/`remove` are synchronous — only `clear` returns a Future, and both call sites await it. `Stores.x` already resolves through GetIt. 1041/1041 passing.

🔎 Confirmed findings (9)
- 🟠 High EntityStore.merge compares timestamps using the incoming serialized ID before applying reconcile(), so legacy name-keyed snippet backups can overwrite a newer local snippet. A pre-ID backup decodes to a fresh generated ID;
currentcontains the local generated ID,incoming[id]has no timestamp for the fresh ID, and the loop accepts the record.SnippetStore.reconcile()then maps it by name onto the existing local ID and write() replaces the newer row/children. The per-record timestamp must be resolved by stable name before the LWW comparison. This is false only if all supported backups always contain stable IDs, which contradicts the explicit legacy reconciliation path and compatibility obligation. (inline) - 🟠 High A partially successful Hive import can permanently regress the schema version and cause m004 to run twice against already-migrated rows. For example, if the key box imports but the server box is temporarily unreadable,
runIfNeededrecords v4 as soon as any box is done; the next launch can run m004 and record v5, but when the pending server box later imports, the all-boxes-success path callsinitAtHiveImport()again and sets the version back to v4. The following launch reruns m004 even though the first run deleted the consumed kv stores and inserted rows into the entity tables, so its plain INSERTs hit primary/unique conflicts (or generate duplicate-renamed keys) and startup migration fails/data is duplicated. This is false only if the import/version update is guaranteed never to complete a pending box after m004 has committed, or if version writes are atomically coupled to the import and migration transaction. (inline) - 🟠 High Malformed JSON-shaped records are not isolated per record in m004: unchecked casts such as
v['name'] as String?,v['ssh'] as Map?, and nested field casts occur after_rowsaccepts any Map, so one malformed server/key/snippet row throws inside the single transaction, rolls back all conversions, and causes the same failure on every launch rather than dropping or recording that bad row while migrating the rest. (inline) - 🟠 High V2 restore does not reconcile container settings as a complete, versioned part of the server record.
mergeiterates only incomingcontainerentries andrestoreOnewrites only fields present in each entry; a host/runtime removed on the source remains on the destination because there is no removal for absent fields. Those writes callContainerStore.put/setType, which stamp the server with the current local timestamp even though this is a restore. Thus a newer incoming server backup can leave stale container configuration in place and then make the destination appear to have a fresh local edit, causing the stale configuration to be uploaded again. (inline) - 🟠 High Entity-store sync can lose a newer edit when two edits occur in the same millisecond, despite the new schema's
revtie-breaker.SyncedTable.stampincrementsrev, butEntityStore.timestampsexports onlyupdated_at;EntityStore.mergecompares only those timestamps and skips when the incoming timestamp is<=the local timestamp. Thus a peer backup containing the later revision with the same millisecond timestamp is treated as stale and is never written. (inline) - 🟠 High Trusted SSH host fingerprints are migrated into the new
known_hosttable, but that table is absent fromTables.syncRootsandBackupV2has no field or merge path for it. After an upgrade,m004deletes the oldsetting/sshKnownHostFingerprintscopy, so the fingerprints are neither included in subsequent backups/sync nor restored on another device;trustHostonly stamps the server and cannot make the child rows travel. (inline) - 🟠 High Deleting a server does not create tombstones for its port-forward children, so a peer can resurrect forwards that were deleted locally. (inline)
- 🟡 Medium Fixture authenticity is only asserted by comments and the checked-in generator recipe, not by a permanent test. The release test checks filenames, a plaintext/encrypted byte heuristic, and migrated values, but has no provenance marker, hash, or independent old-adapter decoding check tying
hive_v1480/hive_v1491bytes to the corresponding release. Replacing a fixture with bytes regenerated by the current adapters (while preserving the represented values) can make the suite pass, even though the test is no longer exercising the shipped source layout; this defeats the stated obligation that migration fixtures be authentic release bytes. (inline) - 🟡 Medium BackupV2 restore is not atomic across the stores it promises to merge together. (inline)
⚠️ Unverified risks (3)
- An upgrade from the shipped v4 SQLite layout cannot create the new entity tables.
Stores.initopens the existing SQLite file and thencreateTablesconstructs Drift with aMigrationStrategywhose only hook isonCreate; Drift does not invokeonCreatefor a non-empty database that already contains v4'skvtable. Consequently an upgrading install reaches m004 withkvpresent butprivate_key,server, etc. absent, and the first INSERT in the migration fails with 'no such table' (or the app has to discard the database). This is false only if every v4 SQLite file is guaranteed to have been created through this exact AppDb/Drift schema and already contains all entity tables, rather than the prior kv-only schema. (lib/data/store/db.dart) - A Hive box is marked fully imported even when individual rows failed to write, so a transient/unsupported row is permanently lost instead of being retried. (lib/data/store/migrations/m003_hive_to_sqlite.dart)
- An existing v4 SQLite database is not usable by the v5 migration because the entity tables are only created from Drift's onCreate callback.
createTables()opens AppDb and executes SELECT 1, but AppDb's migration has no onUpgrade/createAll path; on an existing database containingkv, onCreate is not invoked. Stores.init then calls m004, whose first INSERT targetsprivate_key/serveretc., producing 'no such table' (or leaving the app unable to start) for every normal upgrade from the shipped v4 layout. This would be false only if SqliteStore.openDatabase always supplied a brand-new empty handle rather than reopening the existing v4 database, which contradicts the migration's stated kv-to-table purpose.

- 🟠 High Future-schema refusal occurs after startup has already initialized stores and run writes: Stores.init runs connectionStats.init and HiveImport.runIfNeeded, then removes retired keys and performs setting migrations before SchemaVersion.migrate checks
stored > current;_doDbMigratealso applies app fixups and writes lastVer before that check. A downgrade can therefore sweep/delete data or rewrite settings (and in an incomplete Hive-import state can import/version data) before refusing the newer schema, violating fail-closed downgrade protection. (lib/main.dart) — anchor-unreliable - 🟠 High A downgrade/future-schema install is not rejected before startup mutates its data.
_initDatacompletesStores.init()before_doDbMigrate()performs theSchemaTooNewExceptioncheck, and_doDbMigrateitself runsautoAddNewCards,autoAddNewFuncs, and writeslastVerbefore callingSchemaVersion.migrate. Thus a build supporting v5 opening a database marked v6 can rewrite settings (and, if the import marker is absent while legacy boxes remain,HiveImport.runIfNeededcan also copy legacy rows and reset the stored schema to v4) before eventually refusing or migrating it. A newer build can consequently lose future-build settings or have future data mixed with old imported data instead of getting a clean, recoverable downgrade failure. This is disproven only if all future-version databases are guaranteed to have the import marker and all pre-fixup settings already in exactly the shape that makes every pre-migration write a no-op; the ordering still permits those writes for a valid future database with stale/missing feature keys. (lib/main.dart) — anchor-unreliable - 🟠 High m004 is not tolerant of structurally malformed legacy records: a decoded JSON object with a wrong field type aborts the single migration transaction and leaves schema version at v4, so the same bad row makes every launch fail rather than allowing the other records to migrate. For example, a server with
tags: "x"reaches(v['tags'] as List?)and throws a TypeError; similar unchecked casts exist for nestedssh,custom, and port-forward fields. (lib/data/store/migrations/m004_kv_to_tables.dart) — anchor-unreliable - 🟠 High A too-new remote marker is not tied to the sync operation that observed it, so overlapping syncs can overwrite a newer remote payload.
fromFileclears the static marker at entry; if operation A reads a too-new file and sets the marker, operation B then starts reading a valid file and clears it before A reachesbackup, A's one-time check sees null and delegates to the base uploader. Conversely, a marker set after another operation passes the check can block an unrelated upload. The static UI state also represents whichever caller completed last rather than the current remote. (lib/core/sync.dart) — anchor-outside-diff - 🟠 High Saving a non-active conversation can delete the currently active conversation without selecting a replacement. With 30 conversations for a server and the active row pointing to the oldest one,
save(..., setActive: false)upserts a 31st row and_pruneServerdeletes the oldest row; the FK cascade removesagent_active_conversation, sofetchActivebecomes null even though 29 older/newer conversations remain. This changes active-selection behavior and violates the compound-write invariant for saves that do not explicitly change selection. It would be false only if callers guarantee that the active conversation is never the row pruned by a setActive:false save, but the store API and generic rename/save path do not enforce that. (lib/data/store/agent_conversation.dart) — anchor-outside-diff - 🟠 High The Windows install bundle does not install the native assets produced by the new build hook.
linux/CMakeLists.txtexplicitly copies${PROJECT_BUILD_DIR}native_assets/linux/into the bundle'slib, butwindows/CMakeLists.txtonly installs Flutter/plugin libraries and assets; it has no native-assets install/copy step. A Windows release built withsqlite3/FRB native assets can therefore produce an artifact missing the sqlite3mc andsbm_ffiDLLs (or stale prior files), causing startup/database or native FFI loading failure. (windows/CMakeLists.txt) — anchor-outside-diff - 🟠 High Deleting a private key changes the referencing server (
ssh_key_idbecomes NULL) without updating that server's sync metadata or clearing/replacing its cache. The schema's ON DELETE SET NULL fires inside the raw DELETE, but no ServerStore.touch/stamp is called; the key store only tombstones the key. Thus incremental sync can miss the server's credential change, and a cached ServerStore can continue returning a Spi with the deleted key ID until another server-store write invalidates it. This is false only if every private-key deletion caller separately stamps and invalidates ServerStore, but the schema test and the key store's own delete path provide no such trigger. (lib/data/store/private_key.dart) — anchor-unreliable - 🟠 High Agent conversation rows retain the legacy server_id instead of applying the serverIds remapping. When an old server had an empty/pre-versioned id and is assigned a generated SQLite id, its conversation and active-conversation lookup remain keyed by the old id, so the conversation is not returned for the migrated server and the active link is stale. (lib/data/store/migrations/m004_kv_to_tables.dart) — anchor-unreliable
- 🟠 High Duplicate legacy identity records abort the entire v4-to-v5 transaction instead of being handled as a per-record duplicate.
_migrateServersinsertsiddirectly when the stored id is nonempty, so two KV rows with the same legacyid(or a duplicate row copied from a malformed/merged Hive box) hit the server primary-key constraint; duplicate private-key names similarly hit the unique name constraint only after the name disambiguation is applied to the generated name, while duplicate port-forward ids hit their primary key. The migration then remains at v4 and repeats/fails on every launch. (lib/data/store/migrations/m004_kv_to_tables.dart) — anchor-unreliable - 🟠 High Windows desktop bundles omit the native-assets directory, so the new hook-built sqlite3mc (and the hook-built sbm_ffi library) is not installed beside the executable. (windows/CMakeLists.txt) — anchor-unreliable
- 🟡 Medium If the only legacy artifact left is
conn_stats_index.hive(for example after encrypted boxes were removed or are unavailable),presentis empty andrunIfNeededtakes the fresh-install return path without calling_dropPlaintextIndex; the plaintext server/timestamp index remains permanently on disk despite the migration's security invariant. (lib/data/store/migrations/m003_hive_to_sqlite.dart) — anchor-outside-diff - 🟡 Medium Deleting a server leaves live port-forward provider state inconsistent with the relational database. (lib/data/store/entity_store.dart) — anchor-unreliable
- 🟡 Medium The server provider's ID-change path is unreachable because EntityStore.update rejects the ID change first. (lib/data/provider/server/all.dart) — anchor-outside-diff
- 🟡 Medium Editing a server whose referenced private key was deleted becomes unsaveable even when password or file-path authentication is available. (lib/view/page/server/edit/actions.dart) — anchor-outside-diff
- 🟡 Medium Editing a server whose stored key ID is missing from the current private-key list becomes impossible to save, even when the server still has a valid password credential (or a key-file credential). (lib/view/page/server/edit/actions.dart) — inline-budget
- 🟡 Medium Restoring a legacy v1 backup marks all restored records as new local edits.
Backup.mergeusesreplaceAll, andEntityStore.replaceAllcallssynced.stamp(idOf(resolved))with no source timestamp (and tombstones existing rows at the current time). After a successful restore,Stores.lastModTimeis therefore the restore time rather than the v1 file'slastModTime; the next sync can treat the restored copy as newer and upload it back, contrary to the invariant that restore writes must not masquerade as local edits. (lib/data/store/entity_store.dart) — inline-budget - 🟡 Medium Typed-store validation does not reject malformed object-shaped records, and the restore path silently drops them.
_validateRestorableStoreaccepts anyMap, butEntityStore.mergecatches model decode failures (fromJsonreturns null) and simply continues, leaving the backup read/merge apparently successful while the record is absent locally. A corrupted or incompatible nested credential object is therefore not surfaced as a parse/restore failure and can be followed by a sync upload that omits that record. (lib/data/store/entity_store.dart) — inline-budget - 🟡 Medium The downgrade/version guard can be bypassed by a future envelope whose JSON
versionis a non-integral numeric value (for example4.0).json.decodeproduces adouble, sover is intis false and the file proceeds throughBackupV2.fromJson; the generated reader then callstoInt()and accepts it as version 4, allowing a newer-format file to be restored while silently dropping fields this build does not understand. The existing test only exercises an integerformatVer + 1, so it does not cover the JSON-number representation that defeats the guard. This finding is disproven if the backup contract guarantees that all future writers always emit an integer JSON token and malformed/non-integral versions are rejected before this method (there is no such check in the inspected code). (lib/data/model/app/bak/backup2.dart) — inline-budget - 🟡 Medium Deleting a server leaves its server-scoped agent conversations and active selection behind.
ServersNotifier.delServerdeletes the server and explicitly clears only connection stats; it never callsStores.agentConversation.clearServer(id). The SSH agent history uses the server ID as its conversation scope, so after deletion those rows remain and can be shown by fetchForServer if the ID is reused, while the active row also remains (the conversation table intentionally has no server FK). This violates dependent-data cleanup and can resurrect terminal output under a newly created server with the same ID. It would be false only if server IDs were permanently non-reusable and the product intentionally retained all deleted-server conversations, neither of which is enforced by these paths. (lib/data/provider/server/all.dart) — inline-budget - 🟡 Medium The KV migration can preserve an invalid active selection across servers.
_migrateAgentConversationsrecords active rows by scope, then validates only that the referenced conversation ID exists; it does not verify that the conversation'sserver_idequals the active row's server ID. A legacy active::A pointing to a conversation owned by B is therefore inserted.activeConversationId(A)returns B's ID, whilefetchActive(A)returns null because it detects the mismatch, leaving the persisted active row inconsistent and changing active-selection behavior after migration. It would be false only if legacy data is guaranteed never to contain cross-server active references and the migration's input invariant is externally enforced. (lib/data/store/migrations/m004_kv_to_tables.dart) — inline-budget - 🟡 Medium Deleting a conversation has an unindexed foreign-key cascade path through agent_active_conversation. (lib/data/store/db.dart) — inline-budget
- 🟡 Medium Trusted SSH host keys are no longer included in backups/sync after being moved into the
known_hostchild table.ServerStore.knownHosts/trustHostpersist them in SQLite, butBackupV2.loadFromStoreobtains server records fromStores.server.getAllMap()andServerStore.toJsonserializes onlySpi;BackupV2has no known-host payload and restore never callsknown_host. Consequently a backup made after this migration, or sync to a second device, restores the server but loses its accepted fingerprints and prompts again (and the migrated keys are absent from the next backup). (lib/data/store/server.dart) — inline-budget - 🟡 Medium The permanent release test does not verify all records in the 1491 agent_conversation fixture. The 1491 generator writes both
conv-1forsrv-keyandconv-2forsrv-pwd, but the assertion only queriesfetchForServer('srv-key')and expects one result. A migration that silently dropped every conversation for other servers (or specifically droppedconv-2) would still pass the release test, so it does not cover the shipped fixture's complete agent-conversation obligation. (test/hive_release_migration_test.dart) — inline-budget - 🟡 Medium A private-key deletion does not propagate the database's SET NULL credential change to server state. (lib/data/store/entity_store.dart) — anchor-unreliable
- 🟡 Medium Renaming a snippet changes its persisted order identity and can move it to the end on reload. (lib/data/provider/snippet.dart) — inline-budget
- 🟡 Medium BackupV2 restores container settings without applying the backup's timestamps or force/non-force deletion semantics.
restoreOnecallsContainerStore.put/setType, which stamps the owning server with the current local time, and it never removes host/runtime rows absent from the backup. Thus an older non-forced backup can overwrite a newer server's container host, and a forced restore can leave stale container settings that the backup deleted; the restore also makes the server look like a fresh local edit instead of preserving the incoming timestamp. This would be false only if container settings are intentionally excluded from restore conflict/deletion semantics and are guaranteed never to be changed by restore, which is contradicted byBackupV2.loadFromStoreincluding them andrestoreOnewriting them. (lib/data/model/app/bak/backup2.dart) — inline-budget - 🟡 Medium The v1 Backup restore rewrites entity rows with fresh local timestamps rather than preserving restore metadata.
Backup.mergeinvokesreplaceAll, andEntityStore.replaceAlltombstones every existing row and callssynced.stamp(id)for every restored row with the current clock. After restoring an otherwise old backup,Stores.lastModTimetherefore becomes 'now' and sync can publish the restore as a new local edit, potentially winning over the backup's original version and causing a subsequent peer to receive data that was not actually edited locally. This would be false only if v1 restores are deliberately required to create a new sync version for every row, but the restore code explicitly suppresses change metadata for KV stores and documents that a restore is not an edit. (lib/data/store/entity_store.dart) — inline-budget - 🟡 Medium The per-server connection-stat cap is not oldest-first for equal timestamps.
_pruneorders only bytimestamp DESC, and bothgetConnectionHistoryand the window query use the same non-unique ordering. If 101 attempts arrive in the same millisecond (the new generated IDs intentionally allow this), SQLite may retain/drop arbitrary tied rows rather than dropping the first inserted attempt, and recent ordering/aggregate membership is nondeterministic. It would be false only if the application guarantees timestamps are unique or treats all equal-millisecond attempts as interchangeable for the cap and UI, which conflicts with the explicit same-millisecond preservation requirement and the documented oldest-first cap. (lib/data/store/connection_stats.dart) — inline-budget - 🟡 Medium Saving a non-active conversation can silently erase the active selection when pruning the 31st row. (lib/data/store/agent_conversation.dart) — inline-budget
- 🟡 Medium Container restore operations are not atomic at the graph level.
restoreOne()loops over hosts and runtime but callsput()/setType()separately, and each helper opens and commits its own transaction;restoreLegacyMap()has the same per-entry behavior. If restore is interrupted or a later entry fails, only a subset of a server's child configuration is restored, while each partial write stamps the parent independently. This violates the compound-write/restore atomicity requirement; it would be false only if callers guarantee the process cannot be interrupted between these synchronous calls or the restore format contains at most one child field, which it does not. (lib/data/store/container.dart) — anchor-unreliable - 🟡 Medium Deleting a private key is not fully synchronized: the foreign-key SET NULL mutates referencing server rows, but only the private-key tombstone is recorded. A peer that still has the key and server will merge the server unchanged and retain its ssh_key_id, contrary to the local post-delete state. (lib/data/store/entity_store.dart) — anchor-unreliable
- 🟡 Medium Per-record timestamp conflict resolution happens before legacy/name reconciliation, so a backup record whose serialized id differs from the local generated id can overwrite a newer local record with the same unique name. For example, local snippet B (name N, timestamp 200) and backup snippet A (name N, timestamp 100) are compared as A versus no current entry, then reconcile maps A to B and writes it, losing the newer local content. (lib/data/store/entity_store.dart) — anchor-unreliable
- 🟡 Medium Deleting a private key can leave cached server credentials pointing at a key that no longer exists. (lib/data/store/private_key.dart) — anchor-unreliable
- 🟡 Medium A snippet rename breaks the open editor pane and loses the user's selected identity because the list tracks the edited snippet by its mutable name rather than its stable ID. (lib/view/page/snippet/list.dart) — anchor-unreliable
- 🔵 Low The schema acceptance test does not cover the required cascade from deleting a snippet.
SnippetAutoRunOn.snippetIdis declared withON DELETE CASCADE, buttables_schema_test.dartonly deletes a server and checks that the auto-run row disappears; it never deletes the snippet. A generated-schema regression that removed the snippet-side cascade would therefore pass all current schema tests while leaving orphanedsnippet_auto_run_onrows, violating the table's documented referential-integrity obligation. (test/tables_schema_test.dart) — inline-budget
❓ Low-evidence leads (not confirmed — verify before acting) (2)
- Malformed or structurally incompatible conversation JSON is accepted as a valid empty conversation instead of being rejected, which can expose an apparently empty history and later overwrite the real item list. (lib/data/model/ai/agent_conversation.dart)
- Renaming a snippet does not update the persisted
snippetOrderentry, so a restart drops the renamed snippet from its saved position and can reorder it. (lib/data/provider/snippet.dart)

## Findings on this change (also posted as inline comments) (9)
In lib/data/store/entity_store.dart around line 324, address this finding:
EntityStore.merge compares timestamps using the incoming serialized ID before applying reconcile(), so legacy name-keyed snippet backups can overwrite a newer local snippet. A pre-ID backup decodes to a fresh generated ID; `current` contains the local generated ID, `incoming[id]` has no timestamp for the fresh ID, and the loop accepts the record. `SnippetStore.reconcile()` then maps it by name onto the existing local ID and write() replaces the newer row/children. The per-record timestamp must be resolved by stable name before the LWW comparison. This is false only if all supported backups always contain stable IDs, which contradicts the explicit legacy reconciliation path and compatibility obligation.
In lib/data/store/migrations/m003_hive_to_sqlite.dart around line 152, address this finding:
A partially successful Hive import can permanently regress the schema version and cause m004 to run twice against already-migrated rows. For example, if the key box imports but the server box is temporarily unreadable, `runIfNeeded` records v4 as soon as any box is done; the next launch can run m004 and record v5, but when the pending server box later imports, the all-boxes-success path calls `initAtHiveImport()` again and sets the version back to v4. The following launch reruns m004 even though the first run deleted the consumed kv stores and inserted rows into the entity tables, so its plain INSERTs hit primary/unique conflicts (or generate duplicate-renamed keys) and startup migration fails/data is duplicated. This is false only if the import/version update is guaranteed never to complete a pending box after m004 has committed, or if version writes are atomically coupled to the import and migration transaction.
In lib/data/store/migrations/m004_kv_to_tables.dart around line 176, address this finding:
Malformed JSON-shaped records are not isolated per record in m004: unchecked casts such as `v['name'] as String?`, `v['ssh'] as Map?`, and nested field casts occur after `_rows` accepts any Map, so one malformed server/key/snippet row throws inside the single transaction, rolls back all conversions, and causes the same failure on every launch rather than dropping or recording that bad row while migrating the rest.
In lib/data/model/app/bak/backup2.dart around line 81, address this finding:
V2 restore does not reconcile container settings as a complete, versioned part of the server record. `merge` iterates only incoming `container` entries and `restoreOne` writes only fields present in each entry; a host/runtime removed on the source remains on the destination because there is no removal for absent fields. Those writes call `ContainerStore.put`/`setType`, which stamp the server with the current local timestamp even though this is a restore. Thus a newer incoming server backup can leave stale container configuration in place and then make the destination appear to have a fresh local edit, causing the stale configuration to be uploaded again.
In lib/data/store/entity_store.dart around line 326, address this finding:
Entity-store sync can lose a newer edit when two edits occur in the same millisecond, despite the new schema's `rev` tie-breaker. `SyncedTable.stamp` increments `rev`, but `EntityStore.timestamps` exports only `updated_at`; `EntityStore.merge` compares only those timestamps and skips when the incoming timestamp is `<=` the local timestamp. Thus a peer backup containing the later revision with the same millisecond timestamp is treated as stale and is never written.
In lib/data/store/tables.dart around line 42, address this finding:
Trusted SSH host fingerprints are migrated into the new `known_host` table, but that table is absent from `Tables.syncRoots` and `BackupV2` has no field or merge path for it. After an upgrade, `m004` deletes the old `setting/sshKnownHostFingerprints` copy, so the fingerprints are neither included in subsequent backups/sync nor restored on another device; `trustHost` only stamps the server and cannot make the child rows travel.
In lib/data/store/entity_store.dart around line 240, address this finding:
Deleting a server does not create tombstones for its port-forward children, so a peer can resurrect forwards that were deleted locally.
In test/hive_release_migration_test.dart around line 36, address this finding:
Fixture authenticity is only asserted by comments and the checked-in generator recipe, not by a permanent test. The release test checks filenames, a plaintext/encrypted byte heuristic, and migrated values, but has no provenance marker, hash, or independent old-adapter decoding check tying `hive_v1480`/`hive_v1491` bytes to the corresponding release. Replacing a fixture with bytes regenerated by the current adapters (while preserving the represented values) can make the suite pass, even though the test is no longer exercising the shipped source layout; this defeats the stated obligation that migration fixtures be authentic release bytes.
In lib/data/model/app/bak/backup2.dart around line 77, address this finding:
BackupV2 restore is not atomic across the stores it promises to merge together.
## Additional findings on this change (not posted inline) (35)
In lib/main.dart, address this finding:
Future-schema refusal occurs after startup has already initialized stores and run writes: Stores.init runs connectionStats.init and HiveImport.runIfNeeded, then removes retired keys and performs setting migrations before SchemaVersion.migrate checks `stored > current`; `_doDbMigrate` also applies app fixups and writes lastVer before that check. A downgrade can therefore sweep/delete data or rewrite settings (and in an incomplete Hive-import state can import/version data) before refusing the newer schema, violating fail-closed downgrade protection.
In lib/main.dart, address this finding:
A downgrade/future-schema install is not rejected before startup mutates its data. `_initData` completes `Stores.init()` before `_doDbMigrate()` performs the `SchemaTooNewException` check, and `_doDbMigrate` itself runs `autoAddNewCards`, `autoAddNewFuncs`, and writes `lastVer` before calling `SchemaVersion.migrate`. Thus a build supporting v5 opening a database marked v6 can rewrite settings (and, if the import marker is absent while legacy boxes remain, `HiveImport.runIfNeeded` can also copy legacy rows and reset the stored schema to v4) before eventually refusing or migrating it. A newer build can consequently lose future-build settings or have future data mixed with old imported data instead of getting a clean, recoverable downgrade failure. This is disproven only if all future-version databases are guaranteed to have the import marker and all pre-fixup settings already in exactly the shape that makes every pre-migration write a no-op; the ordering still permits those writes for a valid future database with stale/missing feature keys.
In lib/data/store/migrations/m004_kv_to_tables.dart, address this finding:
m004 is not tolerant of structurally malformed legacy records: a decoded JSON object with a wrong field type aborts the single migration transaction and leaves schema version at v4, so the same bad row makes every launch fail rather than allowing the other records to migrate. For example, a server with `tags: "x"` reaches `(v['tags'] as List?)` and throws a TypeError; similar unchecked casts exist for nested `ssh`, `custom`, and port-forward fields.
In lib/core/sync.dart around line 52, address this finding:
A too-new remote marker is not tied to the sync operation that observed it, so overlapping syncs can overwrite a newer remote payload. `fromFile` clears the static marker at entry; if operation A reads a too-new file and sets the marker, operation B then starts reading a valid file and clears it before A reaches `backup`, A's one-time check sees null and delegates to the base uploader. Conversely, a marker set after another operation passes the check can block an unrelated upload. The static UI state also represents whichever caller completed last rather than the current remote.
In lib/data/store/agent_conversation.dart around line 216, address this finding:
Saving a non-active conversation can delete the currently active conversation without selecting a replacement. With 30 conversations for a server and the active row pointing to the oldest one, `save(..., setActive: false)` upserts a 31st row and `_pruneServer` deletes the oldest row; the FK cascade removes `agent_active_conversation`, so `fetchActive` becomes null even though 29 older/newer conversations remain. This changes active-selection behavior and violates the compound-write invariant for saves that do not explicitly change selection. It would be false only if callers guarantee that the active conversation is never the row pruned by a setActive:false save, but the store API and generic rename/save path do not enforce that.
In windows/CMakeLists.txt around line 78, address this finding:
The Windows install bundle does not install the native assets produced by the new build hook. `linux/CMakeLists.txt` explicitly copies `${PROJECT_BUILD_DIR}native_assets/linux/` into the bundle's `lib`, but `windows/CMakeLists.txt` only installs Flutter/plugin libraries and assets; it has no native-assets install/copy step. A Windows release built with `sqlite3`/FRB native assets can therefore produce an artifact missing the sqlite3mc and `sbm_ffi` DLLs (or stale prior files), causing startup/database or native FFI loading failure.
In lib/data/store/private_key.dart, address this finding:
Deleting a private key changes the referencing server (`ssh_key_id` becomes NULL) without updating that server's sync metadata or clearing/replacing its cache. The schema's ON DELETE SET NULL fires inside the raw DELETE, but no ServerStore.touch/stamp is called; the key store only tombstones the key. Thus incremental sync can miss the server's credential change, and a cached ServerStore can continue returning a Spi with the deleted key ID until another server-store write invalidates it. This is false only if every private-key deletion caller separately stamps and invalidates ServerStore, but the schema test and the key store's own delete path provide no such trigger.
In lib/data/store/migrations/m004_kv_to_tables.dart, address this finding:
Agent conversation rows retain the legacy server_id instead of applying the serverIds remapping. When an old server had an empty/pre-versioned id and is assigned a generated SQLite id, its conversation and active-conversation lookup remain keyed by the old id, so the conversation is not returned for the migrated server and the active link is stale.
In lib/data/store/migrations/m004_kv_to_tables.dart, address this finding:
Duplicate legacy identity records abort the entire v4-to-v5 transaction instead of being handled as a per-record duplicate. `_migrateServers` inserts `id` directly when the stored id is nonempty, so two KV rows with the same legacy `id` (or a duplicate row copied from a malformed/merged Hive box) hit the server primary-key constraint; duplicate private-key names similarly hit the unique name constraint only after the name disambiguation is applied to the generated name, while duplicate port-forward ids hit their primary key. The migration then remains at v4 and repeats/fails on every launch.
In windows/CMakeLists.txt, address this finding:
Windows desktop bundles omit the native-assets directory, so the new hook-built sqlite3mc (and the hook-built sbm_ffi library) is not installed beside the executable.
In lib/data/store/migrations/m003_hive_to_sqlite.dart around line 116, address this finding:
If the only legacy artifact left is `conn_stats_index.hive` (for example after encrypted boxes were removed or are unavailable), `present` is empty and `runIfNeeded` takes the fresh-install return path without calling `_dropPlaintextIndex`; the plaintext server/timestamp index remains permanently on disk despite the migration's security invariant.
In lib/data/store/entity_store.dart, address this finding:
Deleting a server leaves live port-forward provider state inconsistent with the relational database.
In lib/data/provider/server/all.dart around line 391, address this finding:
The server provider's ID-change path is unreachable because EntityStore.update rejects the ID change first.
In lib/view/page/server/edit/actions.dart around line 251, address this finding:
Editing a server whose referenced private key was deleted becomes unsaveable even when password or file-path authentication is available.
In lib/view/page/server/edit/actions.dart around line 502, address this finding:
Editing a server whose stored key ID is missing from the current private-key list becomes impossible to save, even when the server still has a valid password credential (or a key-file credential).
In lib/data/store/entity_store.dart around line 381, address this finding:
Restoring a legacy v1 backup marks all restored records as new local edits. `Backup.merge` uses `replaceAll`, and `EntityStore.replaceAll` calls `synced.stamp(idOf(resolved))` with no source timestamp (and tombstones existing rows at the current time). After a successful restore, `Stores.lastModTime` is therefore the restore time rather than the v1 file's `lastModTime`; the next sync can treat the restored copy as newer and upload it back, contrary to the invariant that restore writes must not masquerade as local edits.
In lib/data/store/entity_store.dart around line 344, address this finding:
Typed-store validation does not reject malformed object-shaped records, and the restore path silently drops them. `_validateRestorableStore` accepts any `Map`, but `EntityStore.merge` catches model decode failures (`fromJson` returns null) and simply continues, leaving the backup read/merge apparently successful while the record is absent locally. A corrupted or incompatible nested credential object is therefore not surfaced as a parse/restore failure and can be followed by a sync upload that omits that record.
In lib/data/model/app/bak/backup2.dart around line 164, address this finding:
The downgrade/version guard can be bypassed by a future envelope whose JSON `version` is a non-integral numeric value (for example `4.0`). `json.decode` produces a `double`, so `ver is int` is false and the file proceeds through `BackupV2.fromJson`; the generated reader then calls `toInt()` and accepts it as version 4, allowing a newer-format file to be restored while silently dropping fields this build does not understand. The existing test only exercises an integer `formatVer + 1`, so it does not cover the JSON-number representation that defeats the guard. This finding is disproven if the backup contract guarantees that all future writers always emit an integer JSON token and malformed/non-integral versions are rejected before this method (there is no such check in the inspected code).
In lib/data/provider/server/all.dart around line 314, address this finding:
Deleting a server leaves its server-scoped agent conversations and active selection behind. `ServersNotifier.delServer` deletes the server and explicitly clears only connection stats; it never calls `Stores.agentConversation.clearServer(id)`. The SSH agent history uses the server ID as its conversation scope, so after deletion those rows remain and can be shown by fetchForServer if the ID is reused, while the active row also remains (the conversation table intentionally has no server FK). This violates dependent-data cleanup and can resurrect terminal output under a newly created server with the same ID. It would be false only if server IDs were permanently non-reusable and the product intentionally retained all deleted-server conversations, neither of which is enforced by these paths.
In lib/data/store/migrations/m004_kv_to_tables.dart around line 593, address this finding:
The KV migration can preserve an invalid active selection across servers. `_migrateAgentConversations` records active rows by scope, then validates only that the referenced conversation ID exists; it does not verify that the conversation's `server_id` equals the active row's server ID. A legacy active::A pointing to a conversation owned by B is therefore inserted. `activeConversationId(A)` returns B's ID, while `fetchActive(A)` returns null because it detects the mismatch, leaving the persisted active row inconsistent and changing active-selection behavior after migration. It would be false only if legacy data is guaranteed never to contain cross-server active references and the migration's input invariant is externally enforced.
In lib/data/store/db.dart around line 402, address this finding:
Deleting a conversation has an unindexed foreign-key cascade path through agent_active_conversation.
In lib/data/store/server.dart around line 312, address this finding:
Trusted SSH host keys are no longer included in backups/sync after being moved into the `known_host` child table. `ServerStore.knownHosts`/`trustHost` persist them in SQLite, but `BackupV2.loadFromStore` obtains server records from `Stores.server.getAllMap()` and `ServerStore.toJson` serializes only `Spi`; `BackupV2` has no known-host payload and restore never calls `known_host`. Consequently a backup made after this migration, or sync to a second device, restores the server but loses its accepted fingerprints and prompts again (and the migrated keys are absent from the next backup).
In test/hive_release_migration_test.dart around line 400, address this finding:
The permanent release test does not verify all records in the 1491 agent_conversation fixture. The 1491 generator writes both `conv-1` for `srv-key` and `conv-2` for `srv-pwd`, but the assertion only queries `fetchForServer('srv-key')` and expects one result. A migration that silently dropped every conversation for other servers (or specifically dropped `conv-2`) would still pass the release test, so it does not cover the shipped fixture's complete agent-conversation obligation.
In lib/data/store/entity_store.dart, address this finding:
A private-key deletion does not propagate the database's SET NULL credential change to server state.
In lib/data/provider/snippet.dart around line 99, address this finding:
Renaming a snippet changes its persisted order identity and can move it to the end on reload.
In lib/data/model/app/bak/backup2.dart around line 83, address this finding:
BackupV2 restores container settings without applying the backup's timestamps or force/non-force deletion semantics. `restoreOne` calls `ContainerStore.put`/`setType`, which stamps the owning server with the current local time, and it never removes host/runtime rows absent from the backup. Thus an older non-forced backup can overwrite a newer server's container host, and a forced restore can leave stale container settings that the backup deleted; the restore also makes the server look like a fresh local edit instead of preserving the incoming timestamp. This would be false only if container settings are intentionally excluded from restore conflict/deletion semantics and are guaranteed never to be changed by restore, which is contradicted by `BackupV2.loadFromStore` including them and `restoreOne` writing them.
In lib/data/store/entity_store.dart around line 197, address this finding:
The v1 Backup restore rewrites entity rows with fresh local timestamps rather than preserving restore metadata. `Backup.merge` invokes `replaceAll`, and `EntityStore.replaceAll` tombstones every existing row and calls `synced.stamp(id)` for every restored row with the current clock. After restoring an otherwise old backup, `Stores.lastModTime` therefore becomes 'now' and sync can publish the restore as a new local edit, potentially winning over the backup's original version and causing a subsequent peer to receive data that was not actually edited locally. This would be false only if v1 restores are deliberately required to create a new sync version for every row, but the restore code explicitly suppresses change metadata for KV stores and documents that a restore is not an edit.
In lib/data/store/connection_stats.dart around line 192, address this finding:
The per-server connection-stat cap is not oldest-first for equal timestamps. `_prune` orders only by `timestamp DESC`, and both `getConnectionHistory` and the window query use the same non-unique ordering. If 101 attempts arrive in the same millisecond (the new generated IDs intentionally allow this), SQLite may retain/drop arbitrary tied rows rather than dropping the first inserted attempt, and recent ordering/aggregate membership is nondeterministic. It would be false only if the application guarantees timestamps are unique or treats all equal-millisecond attempts as interchangeable for the cap and UI, which conflicts with the explicit same-millisecond preservation requirement and the documented oldest-first cap.
In lib/data/store/agent_conversation.dart around line 127, address this finding:
Saving a non-active conversation can silently erase the active selection when pruning the 31st row.
In lib/data/store/container.dart, address this finding:
Container restore operations are not atomic at the graph level. `restoreOne()` loops over hosts and runtime but calls `put()`/`setType()` separately, and each helper opens and commits its own transaction; `restoreLegacyMap()` has the same per-entry behavior. If restore is interrupted or a later entry fails, only a subset of a server's child configuration is restored, while each partial write stamps the parent independently. This violates the compound-write/restore atomicity requirement; it would be false only if callers guarantee the process cannot be interrupted between these synchronous calls or the restore format contains at most one child field, which it does not.
In lib/data/store/entity_store.dart, address this finding:
Deleting a private key is not fully synchronized: the foreign-key SET NULL mutates referencing server rows, but only the private-key tombstone is recorded. A peer that still has the key and server will merge the server unchanged and retain its ssh_key_id, contrary to the local post-delete state.
In lib/data/store/entity_store.dart, address this finding:
Per-record timestamp conflict resolution happens before legacy/name reconciliation, so a backup record whose serialized id differs from the local generated id can overwrite a newer local record with the same unique name. For example, local snippet B (name N, timestamp 200) and backup snippet A (name N, timestamp 100) are compared as A versus no current entry, then reconcile maps A to B and writes it, losing the newer local content.
In lib/data/store/private_key.dart, address this finding:
Deleting a private key can leave cached server credentials pointing at a key that no longer exists.
In lib/view/page/snippet/list.dart, address this finding:
A snippet rename breaks the open editor pane and loses the user's selected identity because the list tracks the edited snippet by its mutable name rather than its stable ID.
In test/tables_schema_test.dart around line 147, address this finding:
The schema acceptance test does not cover the required cascade from deleting a snippet. `SnippetAutoRunOn.snippetId` is declared with `ON DELETE CASCADE`, but `tables_schema_test.dart` only deletes a server and checks that the auto-run row disappears; it never deletes the snippet. A generated-schema regression that removed the snippet-side cascade would therefore pass all current schema tests while leaving orphaned `snippet_auto_run_on` rows, violating the table's documented referential-integrity obligation.

⚠️ The exact legacy backup timestamp encoding is not directly covered by an existing test, but the migration and reconciliation code establish that legacy snippet records are name-keyed and carry timestamps under those keys.
🤖 Prompt for AI agents
In lib/data/store/entity_store.dart, address this finding:
EntityStore.merge compares timestamps using the incoming serialized ID before applying reconcile(), so legacy name-keyed snippet backups can overwrite a newer local snippet. A pre-ID backup decodes to a fresh generated ID; `current` contains the local generated ID, `incoming[id]` has no timestamp for the fresh ID, and the loop accepts the record. `SnippetStore.reconcile()` then maps it by name onto the existing local ID and write() replaces the newer row/children. The per-record timestamp must be resolved by stable name before the LWW comparison. This is false only if all supported backups always contain stable IDs, which contradicts the explicit legacy reconciliation path and compatibility obligation.

⚠️ The exact primary-key conflict described is not inevitable for every choice of pending box because m004 deletes each successfully migrated kv store; however, the schema rollback and incomplete-set migration are definite. For example, if key imports while server is unreadable, m004 advances to v5 and consumes the key kv rows; when server later imports, this branch resets the schema to v4, and m004 runs again with no key rows, so the server's old key reference is resolved to null and the association is permanently lost.
🤖 Prompt for AI agents
In lib/data/store/migrations/m003_hive_to_sqlite.dart, address this finding:
A partially successful Hive import can permanently regress the schema version and cause m004 to run twice against already-migrated rows. For example, if the key box imports but the server box is temporarily unreadable, `runIfNeeded` records v4 as soon as any box is done; the next launch can run m004 and record v5, but when the pending server box later imports, the all-boxes-success path calls `initAtHiveImport()` again and sets the version back to v4. The following launch reruns m004 even though the first run deleted the consumed kv stores and inserted rows into the entity tables, so its plain INSERTs hit primary/unique conflicts (or generate duplicate-renamed keys) and startup migration fails/data is duplicated. This is false only if the import/version update is guaranteed never to complete a pending box after m004 has committed, or if version writes are atomically coupled to the import and migration transaction.

In lib/data/store/migrations/m004_kv_to_tables.dart, address this finding:
Malformed JSON-shaped records are not isolated per record in m004: unchecked casts such as `v['name'] as String?`, `v['ssh'] as Map?`, and nested field casts occur after `_rows` accepts any Map, so one malformed server/key/snippet row throws inside the single transaction, rolls back all conversions, and causes the same failure on every launch rather than dropping or recording that bad row while migrating the rest.

In lib/data/model/app/bak/backup2.dart, address this finding:
V2 restore does not reconcile container settings as a complete, versioned part of the server record. `merge` iterates only incoming `container` entries and `restoreOne` writes only fields present in each entry; a host/runtime removed on the source remains on the destination because there is no removal for absent fields. Those writes call `ContainerStore.put`/`setType`, which stamp the server with the current local timestamp even though this is a restore. Thus a newer incoming server backup can leave stale container configuration in place and then make the destination appear to have a fresh local edit, causing the stale configuration to be uploaded again.

In lib/data/store/entity_store.dart, address this finding:
Entity-store sync can lose a newer edit when two edits occur in the same millisecond, despite the new schema's `rev` tie-breaker. `SyncedTable.stamp` increments `rev`, but `EntityStore.timestamps` exports only `updated_at`; `EntityStore.merge` compares only those timestamps and skips when the incoming timestamp is `<=` the local timestamp. Thus a peer backup containing the later revision with the same millisecond timestamp is treated as stale and is never written.

Fixture authenticity is only asserted by comments and the checked-in generator recipe, not by a permanent test. The release test checks filenames, a plaintext/encrypted byte heuristic, and migrated values, but has no provenance marker, hash, or independent old-adapter decoding check tying `hive_v1480`/`hive_v1491` bytes to the corresponding release. Replacing a fixture with bytes regenerated by the current adapters (while preserving the represented values) can make the suite pass, even though the test is no longer exercising the shipped source layout; this defeats the stated obligation that migration fixtures be authentic release bytes.

BackupV2 restore is not atomic across the stores it promises to merge together.
l10n: `nameAlreadyExistsFmt` was only in en and zh. All 15 locales now, with each one's own quotation marks rather than a copy of the English. - **`merge` dropped every record from a backup that carries no timestamps.** It compared timestamps before asking whether the record exists here, so an addition read as `0 <= 0` — a tie — and was skipped. Every older envelope is like that. A record this device has never seen is an addition; only one the backup knew about and no longer holds is a delete. - **m004 left agent conversations pointing at a pre-migration server id.** A server whose id was regenerated took its conversations' scope with it now, while a scope that names no server — the global agent's — is kept as it is. - m004's `INSERT OR REPLACE` on `agent_conversation` would delete the active row by cascade; `ON CONFLICT DO UPDATE` instead. - `PrivateKeyNotifier.update` refuses a changed id, like the snippet one. - The private key editor's catch no longer clears `_loading` unguarded — the `finally` does it, and only while mounted. Three tests for the restore fixes: a jump host named before it arrives, a backup with no timestamps, and a record the backup never knew about. Not taken, all pre-existing on main and untouched here: the auto-refresh timer dropped without cancelling, two unawaited `connectionStats` clears, and `SandboxImport.run()` ordering — all from #1318. Reverted my own edit to `sshHostKeyFingerprintMd5Hex`: the key has no call site anywhere in `lib`, so whether it should say MD5 or SHA256 is not something this diff can answer. 1044/1044 passing.

- 🟠 High The migration is not restart/idempotent across the commit/version-record boundary: after the transaction commits but before
SchemaVersion.migratestores v5, a crash leaves all consumed KV rows deleted whileserverOrder/snippetOrderremains inkv. On the next launchapplyrebuilds emptyserverIdsandsnippetNames, then_rewriteOrderresolves every existing entry to null and overwrites both order lists with[], losing the user's ordering (and any still-valid setting entries). The claim is false only if the version write is guaranteed atomic with the SQLite transaction, but it is a separate_store(v + 1)operation afterawait step.apply()and uses a different store path. (inline) - 🟠 High Duplicate legacy private-key ids are not handled safely:
_migratePrivateKeysinserts each duplicate as a distinct row but assignsids[oldId] = idrepeatedly, so every server/reference using that old id is silently remapped to whichever duplicate happened to be processed last. If duplicate ids are instead duplicate names represented by different rows, the migration preserves both key blobs but loses the identity of all references to the earlier one. This is disproved only if the v4 format guarantees globally unique key ids for all historical data; the migration's own comment says uniqueness was not enforced. (inline) - 🟠 High Unreadable or non-object source rows are silently made unrecoverable.
_rawcatches JSON decode errors and_rowsskips non-map values, but apply later unconditionally deletes every row in each consumed store. For example, one truncatedserverJSON value is logged and omitted, all other servers migrate, andDELETE FROM kv WHERE store = 'server'erases the truncated record; a later retry or manual recovery cannot recover it. The same applies to malformed rows in keys, snippets, port forwards, docker, conn_stat, and agent_conversation. (inline) - 🟠 High Deleting a server also leaves PortForwardStore's cache containing rows that SQLite has already cascaded away, so a backup made after the deletion can resurrect those deleted forwards. (inline)
- 🟠 High A newer remote snapshot cannot delete per-server container settings:
BackupV2.mergedelegates eachcontainerentry toContainerStore.restoreOne, butrestoreOneonly upserts hosts/runtime and never removes rows absent from the incoming object. For example, device A deletes a server's Docker host (and its server timestamp advances), while device B still has the host; B merges A's newer backup, retains the host, andput/setTypealso stamps the server again, so the next upload can resurrect the supposedly deleted setting on A. This is introduced by the v5 table-backed container restore path; it would be disproved only if container deletion is explicitly intended to be non-synchronizable, contrary to the store comments and the parent-server timestamp design. (inline) - 🟡 Medium The release-fixture suite never exercises a release install whose data boxes are plain (or mixed plain/encrypted).
hive_release_migration_test.dartcopies only the checked-in*_enc.hivefiles, andhive_import_test.dartcreates every data box throughHiveStore, which also produces encrypted files; its only plain file is the deliberately specialconn_stats_index.hive. This leaves the compatibility branch that detects$name.hiveand imports it untested: a regression in plain-box discovery/opening could make old pre-encryption installs look fresh and silently lose their data while all current tests pass. This gap is introduced by the new fixture-based coverage because the fixtures are uniformly encrypted except for the index. It would be disproved if a permanent test copied/constructed each supported box as plain (including a mixed plain/encrypted set) and verified the same full import and second-launch behavior. (inline) - 🟡 Medium Newer-schema refusal happens after several writes, so a downgraded build is not read-only while it is supposed to preserve the newer data.
Stores.initruns setting fixups (removeRetiredKeys, SSH mode/home-tab migrations) and can run Hive import before_doDbMigrate;_doDbMigrateitself updates feature settings before callingSchemaVersion.migrate. With a stored schema version above the supported version, those writes occur and only then doesSchemaTooNewExceptionstop the launch. The claim would be false only if all these preflight writes were proven absent for a newer-schema database, but they are unconditional/flag-driven initialization paths. (inline) - 🟡 Medium BackupV2 restore is not atomic across stores despite the restore contract requiring a coherent backup.
mergecommits key, server, snippet, port-forward, and container changes in separate store operations, then launches history/settings merges separately; a process kill or exception after (for example) server replacement but before settings/history leaves a partially restored backup with no rollback. The claim would be false only if all these store operations shared one SQLite transaction, but each EntityStore/SqliteStore operation commits independently and theFuture.waitis explicitly separate. (inline) - 🟡 Medium The permanent release test does not assert all rows in the v1491 agent-conversation box. The fixture generator writes both
conv-1(forsrv-key) andconv-2(forsrv-pwd), plus an active pointer forsrv-key, but the test only fetchessrv-keyand checks one conversation/one active pointer. A decoder or migration that silently drops every conversation for another server, or drops thesrv-pwdrow, would still pass; this violates the fixture/complete-path assertion requirement. This finding is disproved only if another permanent test enumerates and validatesconv-2and the corresponding active state. (inline)
⛔ Unresolved from previous review (13) — not approved until fixed
- Duplicate legacy identity records abort the entire v4-to-v5 transaction instead of being handled as a per-record duplicate.
_migrateServersinsertsiddirectly when the stored id is nonempty, so two KV rows with the same legacyid(or a duplicate row copied from a malformed/merged Hive box) hit the server primary-key constraint; duplicate private-key names similarly hit the unique name constraint only after the name disambiguation is applied to the generated name, while duplicate port-forward ids hit their primary key. The migration then remains at v4 and repeats/fails on every launch. — The migration still uses a stored nonempty server id verbatim and inserts it into the server primary key, so two legacy rows with the sameidstill cause the transaction to fail. Port-forward ids are likewise still inserted verbatim into their primary key. Although private-key ids are now generated and names are disambiguated, the reported transaction-aborting duplicate-record consequence remains possible for servers and port forwards. - Agent conversation rows retain the legacy server_id instead of applying the serverIds remapping. When an old server had an empty/pre-versioned id and is assigned a generated SQLite id, its conversation and active-conversation lookup remain keyed by the old id, so the conversation is not returned for the migrated server and the active link is stale. — The migration now remaps the SQL
server_idcolumn viascope = serverIds[serverId] ?? serverId, and remaps the active-row key, but it insertsjson.encode(v)without changingv['server_id']. Thus a conversation whose old server id was regenerated is decoded with the legacyconversation.serverId;fetchActive(newId)then rejects it atconversation?.serverId == serverIdand returns null. The migrated conversation therefore still cannot be used as the active conversation for the new server, so the reported defect remains observable. - Deleting a private key changes the referencing server (
ssh_key_idbecomes NULL) without updating that server's sync metadata or clearing/replacing its cache. The schema's ON DELETE SET NULL fires inside the raw DELETE, but no ServerStore.touch/stamp is called; the key store only tombstones the key. Thus incremental sync can miss the server's credential change, and a cached ServerStore can continue returning a Spi with the deleted key ID until another server-store write invalidates it. This is false only if every private-key deletion caller separately stamps and invalidates ServerStore, but the schema test and the key store's own delete path provide no such trigger. — The currentEntityStore.deleteByIdstill executes onlyDELETE FROM private_key ...followed bysynced.tombstone(id)andinvalidate()on the key store. The schema still declaresserver.ssh_key_idasON DELETE SET NULL, but there is no correspondingServerStore.touch/server stamp or server-cache invalidation. Therefore deleting a key can still leave the referencing server'supdated_at/revunchanged and a previously cachedServerStorereturning the old non-null key ID. - lib/data/store/tables.dart: Trusted SSH host fingerprints are migrated into the new
known_hosttable, but that table is absent fromTables.syncRootsandBackupV2has no field or merge path for it. After an upgrade,m004deletes the oldsetting/sshKnownHostFingerprintscopy, so the fingerprints are neither included in subsequent backups/sync nor restored on another device;trustHostonly stamps the server and cannot make the child rows travel. - lib/data/store/entity_store.dart: Entity-store sync can lose a newer edit when two edits occur in the same millisecond, despite the new schema's
revtie-breaker.SyncedTable.stampincrementsrev, butEntityStore.timestampsexports onlyupdated_at;EntityStore.mergecompares only those timestamps and skips when the incoming timestamp is<=the local timestamp. Thus a peer backup containing the later revision with the same millisecond timestamp is treated as stale and is never written. — The defect remains:timestampsstill exports onlyupdated_atfor each row, omittingrev, andmergestill rejects a known record when(bakTs ?? 0) <= (current[id] ?? 0). Therefore a backup for a later revision with the same millisecond timestamp is still skipped before its record is written. - lib/data/store/agent_conversation.dart: Saving a non-active conversation can delete the currently active conversation without selecting a replacement. With 30 conversations for a server and the active row pointing to the oldest one,
save(..., setActive: false)upserts a 31st row and_pruneServerdeletes the oldest row; the FK cascade removesagent_active_conversation, sofetchActivebecomes null even though 29 older/newer conversations remain. This changes active-selection behavior and violates the compound-write invariant for saves that do not explicitly change selection. It would be false only if callers guarantee that the active conversation is never the row pruned by a setActive:false save, but the store API and generic rename/save path do not enforce that. - lib/data/model/app/bak/backup2.dart: V2 restore does not reconcile container settings as a complete, versioned part of the server record.
mergeiterates only incomingcontainerentries andrestoreOnewrites only fields present in each entry; a host/runtime removed on the source remains on the destination because there is no removal for absent fields. Those writes callContainerStore.put/setType, which stamp the server with the current local timestamp even though this is a restore. Thus a newer incoming server backup can leave stale container configuration in place and then make the destination appear to have a fresh local edit, causing the stale configuration to be uploaded again. - lib/core/sync.dart: A too-new remote marker is not tied to the sync operation that observed it, so overlapping syncs can overwrite a newer remote payload.
fromFileclears the static marker at entry; if operation A reads a too-new file and sets the marker, operation B then starts reading a valid file and clears it before A reachesbackup, A's one-time check sees null and delegates to the base uploader. Conversely, a marker set after another operation passes the check can block an unrelated upload. The static UI state also represents whichever caller completed last rather than the current remote. - m004 is not tolerant of structurally malformed legacy records: a decoded JSON object with a wrong field type aborts the single migration transaction and leaves schema version at v4, so the same bad row makes every launch fail rather than allowing the other records to migrate. For example, a server with
tags: "x"reaches(v['tags'] as List?)and throws a TypeError; similar unchecked casts exist for nestedssh,custom, and port-forward fields. — The current_migrateServersstill evaluates(v['tags'] as List? ?? const []), so a decoded server record withtags: "x"throws a TypeError inside the single migration transaction. The same unchecked shape casts remain for fields such asssh,custom, andjumpIds, so malformed legacy data can still abort m004 and prevent the schema-version advance. - A downgrade/future-schema install is not rejected before startup mutates its data.
_initDatacompletesStores.init()before_doDbMigrate()performs theSchemaTooNewExceptioncheck, and_doDbMigrateitself runsautoAddNewCards,autoAddNewFuncs, and writeslastVerbefore callingSchemaVersion.migrate. Thus a build supporting v5 opening a database marked v6 can rewrite settings (and, if the import marker is absent while legacy boxes remain,HiveImport.runIfNeededcan also copy legacy rows and reset the stored schema to v4) before eventually refusing or migrating it. A newer build can consequently lose future-build settings or have future data mixed with old imported data instead of getting a clean, recoverable downgrade failure. This is disproven only if all future-version databases are guaranteed to have the import marker and all pre-fixup settings already in exactly the shape that makes every pre-migration write a no-op; the ordering still permits those writes for a valid future database with stale/missing feature keys. — The ordering defect remains:_initDataawaitsStores.init()before_doDbMigrate(), whileStores.init()still performsHiveImport.runIfNeeded()and setting fixups. In_doDbMigrate(), the future-schema check is still insideSchemaVersion.migrate()and occurs only after thelastVerblock can callautoAddNewCards,autoAddNewFuncs, and updatelastVer. Therefore a database whose stored schema version exceeds the supported version can still be mutated beforeSchemaTooNewExceptionis thrown. - Future-schema refusal occurs after startup has already initialized stores and run writes: Stores.init runs connectionStats.init and HiveImport.runIfNeeded, then removes retired keys and performs setting migrations before SchemaVersion.migrate checks
stored > current;_doDbMigratealso applies app fixups and writes lastVer before that check. A downgrade can therefore sweep/delete data or rewrite settings (and in an incomplete Hive-import state can import/version data) before refusing the newer schema, violating fail-closed downgrade protection. — The downgrade is still not fail-closed before initialization._initDataawaitsStores.init()(lib/main.dart:153–170), andStores.initopens/creates SQLite, initializes stores, runsconnectionStats.init(),HiveImport.runIfNeeded(), removes retired keys, and performs setting migrations before_doDbMigrateis called (lib/data/res/store.dart:61–99). In_doDbMigrate, app-level fixups andlastVer.put(newVer)still execute beforeSchemaVersion.migrateperforms thestored > currentrefusal (lib/main.dart:227–243). Thus a future-schema database can still be swept, imported, have retired settings removed/migrated, or receive app fixup writes before refusal. - lib/data/store/migrations/m003_hive_to_sqlite.dart: A partially successful Hive import can permanently regress the schema version and cause m004 to run twice against already-migrated rows. For example, if the key box imports but the server box is temporarily unreadable,
runIfNeededrecords v4 as soon as any box is done; the next launch can run m004 and record v5, but when the pending server box later imports, the all-boxes-success path callsinitAtHiveImport()again and sets the version back to v4. The following launch reruns m004 even though the first run deleted the consumed kv stores and inserted rows into the entity tables, so its plain INSERTs hit primary/unique conflicts (or generate duplicate-renamed keys) and startup migration fails/data is duplicated. This is false only if the import/version update is guaranteed never to complete a pending box after m004 has committed, or if version writes are atomically coupled to the import and migration transaction. - lib/data/store/entity_store.dart: EntityStore.merge compares timestamps using the incoming serialized ID before applying reconcile(), so legacy name-keyed snippet backups can overwrite a newer local snippet. A pre-ID backup decodes to a fresh generated ID;
currentcontains the local generated ID,incoming[id]has no timestamp for the fresh ID, and the loop accepts the record.SnippetStore.reconcile()then maps it by name onto the existing local ID and write() replaces the newer row/children. The per-record timestamp must be resolved by stable name before the LWW comparison. This is false only if all supported backups always contain stable IDs, which contradicts the explicit legacy reconciliation path and compatibility obligation. — The current merge still performs the timestamp lookup and known-record decision using the serializedidbefore deserialization andreconcile():final bakTs = incoming[id]andfinal known = current.containsKey(id)occur beforefinal resolved = reconcile(item).SnippetStore.reconcile()still maps a legacy decoded snippet to the existing row by name, so a fresh generated ID can bypass the local timestamp check and then overwrite that row and its children.
⚠️ Unverified risks (1)
- Duplicate legacy server identities are not treated as malformed data: when two server records carry the same non-empty
v['id'],_migrateServersattempts two inserts with the same primary key and the second raisesSQLITE_CONSTRAINT, rolling back the whole transaction. The same all-or-nothing failure occurs for duplicate port-forward ids in_migratePortForwards. Since the version is not advanced after a failed step, a device containing such data is permanently stuck retrying the migration rather than dropping or deterministically repairing the duplicate. This would be false only if the old stores guarantee unique embedded server ids and forward ids; the requested migration's duplicate-corruption obligation and the code's lack of conflict handling do not establish that guarantee.

📋 Additional findings from this change (not shown inline) (23)
- 🟠 High An install containing only the legacy plaintext
conn_stats_index.hiveis treated as a fresh install and the plaintext file is left behind.runIfNeededbuildspresentonly from_boxes(which intentionally excludesconn_stats_index); when that list is empty it returns throughSchemaVersion.initFresh()without calling_dropPlaintextIndex. The tests cover an entirely empty directory and an index alongside all normal boxes, but not the empty-legacy-box-list/index-only variant, so this data-protection cleanup regression is currently undetected. The claim would be false if another startup path independently deletes the index before this code runs, or if an index-only install is intentionally outside the supported legacy states. (lib/data/store/migrations/m003_hive_to_sqlite.dart) — anchor-outside-diff - 🟠 High Duplicate legacy server identities abort the entire migration instead of being handled. If two kv/server rows have the same non-empty
v['id'](or a generated empty-id happens to collide), both are converted to that id and the secondINSERT INTO serverviolates the primary key. Because apply is retried at v4 after rollback, the same malformed/duplicate input fails on every launch; no records are migrated and the user cannot reach v5. The same unguarded behavior exists for duplicate port-forward ids at its INSERT. (lib/data/store/migrations/m004_kv_to_tables.dart) — per-file-budget - 🟠 High A syntactically valid JSON object with a malformed field can brick the migration rather than be skipped or dropped. For example, a legacy server row with
"ssh":"corrupt"reachesv['ssh'] as Map?and throws a cast error (similarlytagsas a non-list,envsas a non-map, orjumpIdsas a non-list). The transaction rolls back, SchemaVersion remains v4, and the same row throws on every launch; unlike_rows's JSON-level catch, there is no per-record validation boundary. (lib/data/store/migrations/m004_kv_to_tables.dart) — per-file-budget - 🟠 High KvToTablesMigration does not actually skip malformed record maps; it skips only non-map rows, then uses unchecked casts while migrating each map. For example a corrupted key row such as
{ "private_key": 42 }reaches_migratePrivateKeys, where(row.value['private_key'] ?? row.value['key']) as String?throws a TypeError. Becauseapplywraps the whole operation in one transaction, that one record aborts migration and prevents all otherwise valid records from being migrated, contrary to the per-record malformed-data compatibility promise. (lib/data/store/migrations/m004_kv_to_tables.dart) — per-file-budget - 🟡 Medium The plaintext connection-stat index is not reliably removed.
presentdeliberately excludesconn_stats_index, so an install containing only that legacy file is treated as a fresh install and returns fromrunIfNeededwithout calling_dropPlaintextIndex. Also, when any encrypted box is unread, the method returns before cleanup, and when deletion itself fails_dropPlaintextIndexonly logs the error before writing the permanent import marker. Thus a stale<documents>/conn_stats_index.hivecan remain readable indefinitely, contrary to the migration's encryption invariant, including after a successful retry or on platforms where the file is temporarily undeletable. This is false only if the index is guaranteed to coexist with a recognized box and deletion is guaranteed to succeed before the marker is persisted. (lib/data/store/migrations/m003_hive_to_sqlite.dart) — anchor-outside-diff - 🟡 Medium Orphaned agent conversations are retained and can be made active instead of being dropped. The only non-server scope is the explicit global sentinel
__global_agent__, but this code maps any unknownserverIdwithserverIds[serverId] ?? serverIdand likewise any unknownactive::scope withserverIds[scope] ?? scope. Thus a conversation belonging to a deleted/malformed server remains under its stale id, and its active row is recreated; it is then visible tofetchForServer(staleId)and consumes the local conversation quota despite having no owning server. This would be disproved only if every unknown scope in the legacy box is guaranteed to be the global sentinel, which is incompatible with the server-scoped storage format and the migration's stated orphan-cleanup rule. (lib/data/store/migrations/m004_kv_to_tables.dart) — per-file-budget - 🟡 Medium The migration tests never exercise a legacy data box that exists only as
<name>.hive(the pre-encryption variant).HiveImport.runIfNeededexplicitly promises to detect and import either<name>_enc.hiveor<name>.hive, butseedHive()creates boxes throughHiveStore(encrypted), and the release test copies only_encfixtures; its added plainsnippet.hiveis an empty directory used to force an open failure whilesnippet_enc.hiveremains the actual data source, not a plain-data import. Consequently a regression in the plain-file discovery/open path can pass all permanent tests. This is disproved only if another permanent migration test seeds real records in a plain legacy box and runs the full import. (test/hive_import_test.dart) — inline-budget - 🟡 Medium The v4→v5 migration is not recoverable when legacy KV contains duplicate server IDs:
_migrateServersinserts each row'sv['id']directly as the new primary key, without deduplicating or skipping collisions. Two legacy records under different KV keys can carry the same non-emptyid; the second INSERT then raises a SQLite UNIQUE/PRIMARY KEY exception, aborting the transaction, whileSchemaVersionremains v4. Every subsequent launch retries the same failing migration, so the app cannot reach the v5 layout or expose the data for repair. This is especially relevant because the migration already claims to tolerate/drop malformed legacy records, but this collision path is fatal. (lib/data/store/migrations/m004_kv_to_tables.dart) — inline-budget - 🟡 Medium The migration drops the legacy per-record modification timestamps for every entity.
_intoKvTablewrites every imported row withupdated_at = 0; m004 merely copies that zero intoprivate_key,server,snippet, andport_forward. Any legacy timestamp metadata row is skipped by_rawbecause it uses the internal prefix filter, so it cannot be used to populate those columns. Consequently an install with existing Hive sync history upgrades with all entity rows looking unchanged/older (Stores.lastModTimeand per-record timestamps are zero), and equal-timestamp merge logic can fail to propagate an actual newer local record or deletion. This would be false only if the released Hive layout never stored per-record modification metadata and zero timestamps were explicitly the intended compatibility semantics. (lib/data/store/migrations/m003_hive_to_sqlite.dart) — inline-budget - 🟡 Medium The private-key editor can write to disposed controllers after navigation away while asynchronous clipboard/file loading is still in flight. (lib/view/page/private_key/edit.dart) — inline-budget
- 🟡 Medium If the user leaves this page before Clipboard.getData or the file picker/read completes, the continuation still assigns _keyController.text even though dispose() has already disposed that controller, producing an uncaught disposed-controller error. The claim is false only if every one of these asynchronous operations is guaranteed to complete before route disposal, which Flutter's clipboard/file APIs do not guarantee. (lib/view/page/private_key/edit.dart) — inline-budget
- 🟡 Medium When decryptPem or a durable key write fails (other than DuplicateNameException), _onTapSave catches it, displays a toast, and then rethrows from an async-void callback. This turns ordinary wrong-password/read/write failures into uncaught asynchronous errors; the claim is false only if the application intentionally has a top-level policy that treats every such rethrow as a handled UI error, which is not present in this handler. (lib/view/page/private_key/edit.dart) — inline-budget
- 🟡 Medium The positive file-tab restore tests are false-green: they preload the expected JSON, pump the page, then assert only that the store still contains the same JSON, so a no-op restore (or one that never opens
/tmp/somewhere//var/log) passes. (test/file_tab_restore_test.dart) — inline-budget - 🟡 Medium The declared SDK floor does not match the resolved dependency graph:
pubspec.yamlpermits Dart 3.11 (sdk: ">=3.11.0"), while the checked-inpubspec.lockrecordssdks.dart: ">=3.12.0 <4.0.0". A release or CI job using Dart/Flutter with Dart 3.11 can therefore fail dependency resolution before the Drift/sqlite3mc build hook runs, despite satisfying this package's manifest. This is false only if the project’s supported toolchain is separately guaranteed to be Dart >=3.12 and the manifest floor is intentionally unused. (pubspec.yaml) — inline-budget - 🟡 Medium The English and Chinese architecture pages do not satisfy the documented database/test contract: they describe ownership and migration steps but omit the required startup order (
SqliteStore.openDatabase→createTables→ store init →HiveImport→ app migration) and the in-memory test lifecycle (openTestDb, foreign-key pragma,forTest, andSqliteDb.closeteardown). They also state that all models use Freezed with built-in JSON serialization, while the repository guidance explicitly documents exceptions such as hand-writtenPortForwardConfig.toJsonand frozen legacy adapters. A contributor following the architecture page can therefore initialize stores before the schema or create file-backed widget-test databases, and can incorrectly add current model adapters to the legacy import path. (docs/src/content/docs/development/architecture.md) — inline-budget - 🟡 Medium The architecture documentation omits the mandatory in-memory database lifecycle for widget/store tests. The repository's test helper opens an in-memory connection, enables the per-connection foreign-key pragma, creates the Drift schema, and every caller must close
SqliteDbin tearDown and use each store'sforTest()instance to avoid singleton list-cache leakage; the current test suite demonstrates this pattern. Without documenting it, a new table-backed widget test can use the normal singleton/file-backed store, leave writes pending in Flutter's fake-async zone, and hang teardown or leak cached rows into later tests. This would be false if the architecture documentation contained an equivalent test-lifecycle section, but neither language page mentionsopenTestDb,SqliteDb.close,forTest, or the fake-async/file-write hazard. (docs/src/content/docs/development/architecture.md) — inline-budget - 🟡 Medium A malformed but valid-JSON object in a legacy entity row can abort the entire v4-to-v5 migration instead of being skipped, leaving the database at v4 and causing the same failure on every retry. (lib/data/store/migrations/m004_kv_to_tables.dart) — anchor-unreliable
- 🟡 Medium The migration documentation still references the deleted
test/hive_v1466_migration_test.dartand presents the old single-fixture workflow as the active test matrix. (docs/src/content/docs/development/testing.md) — inline-budget - 🟡 Medium The main SSH restore test does not establish that either restored tab was actually opened. It writes two entries, pumps, then asserts that the store still contains the two original entries and their tmux windows; a broken
_restoreTabsthat returned without calling_openwould satisfy that assertion. The onlySSHPageassertion in this file is for the separate server/local selection case, so the central two-tab restoration behavior is not exercised by the test. (test/ssh_tab_restore_test.dart) — inline-budget - 🟡 Medium The architecture documentation does not state the startup ordering that makes the storage migration safe, so it omits a critical schema ownership invariant.
Stores.initmust open the SQLite handle, create Drift's tables, initialize KV stores, import Hive, and only then runSchemaVersion.migratebefore providers are loaded;HiveImportitself is not a substitute for the later v5 table migration. The current architecture page only lists the two migration names and their transformations, without this ordering or the fact thatmain.dartdeliberately runs_doDbMigratebeforerunApp. A contributor following the page could initialize/read entity stores beforecreateTablesor run m004 before m003, yielding missing-table failures or stranded rows. This finding would be false if another architecture section explicitly documented and linked this exact order, but neither the English nor Chinese page does. (docs/src/content/docs/development/architecture.md) — inline-budget - 🟡 Medium When an encrypted legacy box is temporarily unreadable, the import returns before removing the plaintext connection-stat index. The
unreadearly-return path calls_setDoneBoxesandinitAtHiveImportbut never_dropPlaintextIndex; if keychain access never recovers, every launch keeps the plaintext index beside the new database indefinitely. Even when recovery eventually succeeds, the sensitive artifact remains during the whole retry window. (lib/data/store/migrations/m003_hive_to_sqlite.dart) — anchor-unreliable - 🟡 Medium The checked-in fixture tests do not provide an enforceable provenance check that the binary bytes came from the tagged releases. The generator programs are
.dart.txtrecipes and the release test only verifies filenames, encryption, and selected decoded values; it never compares fixture bytes against a reproducible output/hash or otherwise proves that the checked-in files were generated by the corresponding release worktree. Thus a fixture regenerated with the current adapters (or hand-edited to match the selected assertions) can pass, defeating the permanent regression test's requirement that it be fed bytes the migrated-from release actually wrote. This would be disproved if CI or the test suite regenerated each fixture using the release tag's generator/adapters and compared the resulting bytes (or checked in a verifiable provenance/hash manifest). (test/fixtures/README.md) — anchor-unreliable - 🔵 Low The architecture pages make a false blanket claim that all data models use Freezed and have built-in JSON serialization.
lib/data/model/server/port_forward.dartcontains the explicitly exceptionalPortForwardStatusclass, andPortForwardConfighas no generated.g.dart; its hand-writtentoJsonis required because KV encoding otherwise returns failure and silently drops port forwards. The docs therefore omit a generated-code/storage contract that is important to this migration and could lead a maintainer to remove the manual serializer or assume regeneration is sufficient. This would be false if the documentation qualified the claim or documented this exception elsewhere on the architecture page, but it currently does not. (docs/src/content/docs/development/architecture.md) — anchor-unreliable
♻️ Previously reported (still present) (5)
- 🟠 High The per-store caches and change streams are not invalidated when another store causes a foreign-key cascade or SET NULL. For example, after PortForwardStore.fetch() caches a forward, ServerStore.deleteById() deletes the server and cascades port_forward, but only ServerStore.invalidate() runs; the port-forward store continues returning the deleted object and emits no watch event. Likewise deleting a private key SET NULLs server.ssh_key_id without invalidating ServerStore, and deleting a server removes SnippetStore auto-run children without invalidating SnippetStore. This violates cache freshness and public reader/notification behavior; it would be false only if all such cascaded tables were guaranteed never to have been cached or observed between the writes. (lib/data/store/entity_store.dart) — previously-reported
- 🟠 High If every recognized encrypted box fails to open, the app does not have a retryable startup state:
donestays empty,SchemaVersionretains its default v2, and_doDbMigrateis called afterStores.initwith only a v4→v5 migration.SchemaVersion.migratetherefore throwsStateError('Missing schema migration from v2 to v3')before the app starts. A locked device whose keychain is unavailable for all Hive boxes can hit exactly this path; even thoughrunIfNeededlogs that the boxes are left for the next launch, the launch fails before becoming usable. This is false only if the default schema version is guaranteed to be v4 for all such SQLite databases or the caller skips schema migration while unread boxes remain. (lib/data/store/migrations/m003_hive_to_sqlite.dart) — previously-reported - 🟠 High BackupV2 container restoration applies stale values unconditionally, cannot propagate child-field deletions, and stamps restored data as a new local edit. (lib/data/model/app/bak/backup2.dart) — previously-reported
- 🟡 Medium Deleting a server leaves sync-root port forwards without tombstones, so the deletion cannot converge across devices. (lib/data/store/entity_store.dart) — previously-reported
- 🟡 Medium The permanent fixture assertions depend on wall-clock time while the generated stats have a fixed timestamp of 2026-01-01. On an initial launch within 30 days of that timestamp, the second-launch assertion expects
conn_statto be empty even thoughConnectionStatsStore._expiremust retain those rows; on a run sufficiently after that date, the first-launch 120-row assertion can instead be affected by the sweep if setup/order changes. Thus the test is not stable over its intended permanent lifetime and does not reliably prove the second-launch behavior. This is disproved only if the test pins the clock or the fixture timestamp is guaranteed older than the retention window in every supported test run.

❓ Low-evidence leads (not confirmed — verify before acting) (5)
- A decryption, file-read, or provider write failure is rethrown after showing a toast from the async-void save handler, so the user gets an uncaught asynchronous exception rather than a handled validation/error result. (lib/view/page/private_key/edit.dart)
- Unreadable sensitive/source rows are deleted rather than retained for recovery.
_rawcatches JSON decode failures and skips the row, but m004 unconditionally executesDELETE FROM kv WHERE store = ?for every consumed store after migrating the rows it could decode. A truncated or otherwise malformed server/key/snippet/stat row therefore disappears from both the relational tables and the original KV copy, violating malformed-data tolerance and the requirement that migration failure not destroy recoverable source data. (lib/data/store/migrations/m004_kv_to_tables.dart) - A legacy install containing only
conn_stats_index.hiveis treated as a fresh install and the plaintext sensitive index is left behind.presentis built only from_boxes.keys, which excludesconn_stats_index; with no encrypted/recognized box it is empty, so the code callsSchemaVersion.initFresh()and returns before_dropPlaintextIndex(dir). The old connection identifiers/stat index therefore remains readable on disk and is never cleaned up. (lib/data/store/migrations/m003_hive_to_sqlite.dart) - Restoring a v5 backup cannot clear container settings that were deleted on the source device.
BackupV2.mergeonly iterates entries present incontainerand callsrestoreOne; it never removes existing container-host/runtime rows absent from the backup. Thus restoring an intentionally cleared v5 container configuration onto a device that still has the old row leaves that row authoritative and resurrects the configuration, unlike the other mergeable stores' deletion handling. (lib/data/model/app/bak/backup2.dart) - The entity caches become stale when a private key is deleted: the database nulls server.ssh_key_id via FK SET NULL, but ServerStore's cached Spi still contains the deleted key ID and can be backed up or reused.

Somewhere in the code under review, address this finding:
Duplicate legacy identity records abort the entire v4-to-v5 transaction instead of being handled as a per-record duplicate. `_migrateServers` inserts `id` directly when the stored id is nonempty, so two KV rows with the same legacy `id` (or a duplicate row copied from a malformed/merged Hive box) hit the server primary-key constraint; duplicate private-key names similarly hit the unique name constraint only after the name disambiguation is applied to the generated name, while duplicate port-forward ids hit their primary key. The migration then remains at v4 and repeats/fails on every launch.
Somewhere in the code under review, address this finding:
Agent conversation rows retain the legacy server_id instead of applying the serverIds remapping. When an old server had an empty/pre-versioned id and is assigned a generated SQLite id, its conversation and active-conversation lookup remain keyed by the old id, so the conversation is not returned for the migrated server and the active link is stale.
Somewhere in the code under review, address this finding:
Deleting a private key changes the referencing server (`ssh_key_id` becomes NULL) without updating that server's sync metadata or clearing/replacing its cache. The schema's ON DELETE SET NULL fires inside the raw DELETE, but no ServerStore.touch/stamp is called; the key store only tombstones the key. Thus incremental sync can miss the server's credential change, and a cached ServerStore can continue returning a Spi with the deleted key ID until another server-store write invalidates it. This is false only if every private-key deletion caller separately stamps and invalidates ServerStore, but the schema test and the key store's own delete path provide no such trigger.
In lib/data/store/tables.dart, address this finding:
Trusted SSH host fingerprints are migrated into the new `known_host` table, but that table is absent from `Tables.syncRoots` and `BackupV2` has no field or merge path for it. After an upgrade, `m004` deletes the old `setting/sshKnownHostFingerprints` copy, so the fingerprints are neither included in subsequent backups/sync nor restored on another device; `trustHost` only stamps the server and cannot make the child rows travel.
In lib/data/store/entity_store.dart, address this finding:
Entity-store sync can lose a newer edit when two edits occur in the same millisecond, despite the new schema's `rev` tie-breaker. `SyncedTable.stamp` increments `rev`, but `EntityStore.timestamps` exports only `updated_at`; `EntityStore.merge` compares only those timestamps and skips when the incoming timestamp is `<=` the local timestamp. Thus a peer backup containing the later revision with the same millisecond timestamp is treated as stale and is never written.
In lib/data/store/agent_conversation.dart, address this finding:
Saving a non-active conversation can delete the currently active conversation without selecting a replacement. With 30 conversations for a server and the active row pointing to the oldest one, `save(..., setActive: false)` upserts a 31st row and `_pruneServer` deletes the oldest row; the FK cascade removes `agent_active_conversation`, so `fetchActive` becomes null even though 29 older/newer conversations remain. This changes active-selection behavior and violates the compound-write invariant for saves that do not explicitly change selection. It would be false only if callers guarantee that the active conversation is never the row pruned by a setActive:false save, but the store API and generic rename/save path do not enforce that.
In lib/data/model/app/bak/backup2.dart, address this finding:
V2 restore does not reconcile container settings as a complete, versioned part of the server record. `merge` iterates only incoming `container` entries and `restoreOne` writes only fields present in each entry; a host/runtime removed on the source remains on the destination because there is no removal for absent fields. Those writes call `ContainerStore.put`/`setType`, which stamp the server with the current local timestamp even though this is a restore. Thus a newer incoming server backup can leave stale container configuration in place and then make the destination appear to have a fresh local edit, causing the stale configuration to be uploaded again.
In lib/core/sync.dart, address this finding:
A too-new remote marker is not tied to the sync operation that observed it, so overlapping syncs can overwrite a newer remote payload. `fromFile` clears the static marker at entry; if operation A reads a too-new file and sets the marker, operation B then starts reading a valid file and clears it before A reaches `backup`, A's one-time check sees null and delegates to the base uploader. Conversely, a marker set after another operation passes the check can block an unrelated upload. The static UI state also represents whichever caller completed last rather than the current remote.
Somewhere in the code under review, address this finding:
m004 is not tolerant of structurally malformed legacy records: a decoded JSON object with a wrong field type aborts the single migration transaction and leaves schema version at v4, so the same bad row makes every launch fail rather than allowing the other records to migrate. For example, a server with `tags: "x"` reaches `(v['tags'] as List?)` and throws a TypeError; similar unchecked casts exist for nested `ssh`, `custom`, and port-forward fields.
Somewhere in the code under review, address this finding:
A downgrade/future-schema install is not rejected before startup mutates its data. `_initData` completes `Stores.init()` before `_doDbMigrate()` performs the `SchemaTooNewException` check, and `_doDbMigrate` itself runs `autoAddNewCards`, `autoAddNewFuncs`, and writes `lastVer` before calling `SchemaVersion.migrate`. Thus a build supporting v5 opening a database marked v6 can rewrite settings (and, if the import marker is absent while legacy boxes remain, `HiveImport.runIfNeeded` can also copy legacy rows and reset the stored schema to v4) before eventually refusing or migrating it. A newer build can consequently lose future-build settings or have future data mixed with old imported data instead of getting a clean, recoverable downgrade failure. This is disproven only if all future-version databases are guaranteed to have the import marker and all pre-fixup settings already in exactly the shape that makes every pre-migration write a no-op; the ordering still permits those writes for a valid future database with stale/missing feature keys.
Somewhere in the code under review, address this finding:
Future-schema refusal occurs after startup has already initialized stores and run writes: Stores.init runs connectionStats.init and HiveImport.runIfNeeded, then removes retired keys and performs setting migrations before SchemaVersion.migrate checks `stored > current`; `_doDbMigrate` also applies app fixups and writes lastVer before that check. A downgrade can therefore sweep/delete data or rewrite settings (and in an incomplete Hive-import state can import/version data) before refusing the newer schema, violating fail-closed downgrade protection.
In lib/data/store/migrations/m003_hive_to_sqlite.dart, address this finding:
A partially successful Hive import can permanently regress the schema version and cause m004 to run twice against already-migrated rows. For example, if the key box imports but the server box is temporarily unreadable, `runIfNeeded` records v4 as soon as any box is done; the next launch can run m004 and record v5, but when the pending server box later imports, the all-boxes-success path calls `initAtHiveImport()` again and sets the version back to v4. The following launch reruns m004 even though the first run deleted the consumed kv stores and inserted rows into the entity tables, so its plain INSERTs hit primary/unique conflicts (or generate duplicate-renamed keys) and startup migration fails/data is duplicated. This is false only if the import/version update is guaranteed never to complete a pending box after m004 has committed, or if version writes are atomically coupled to the import and migration transaction.
In lib/data/store/entity_store.dart, address this finding:
EntityStore.merge compares timestamps using the incoming serialized ID before applying reconcile(), so legacy name-keyed snippet backups can overwrite a newer local snippet. A pre-ID backup decodes to a fresh generated ID; `current` contains the local generated ID, `incoming[id]` has no timestamp for the fresh ID, and the loop accepts the record. `SnippetStore.reconcile()` then maps it by name onto the existing local ID and write() replaces the newer row/children. The per-record timestamp must be resolved by stable name before the LWW comparison. This is false only if all supported backups always contain stable IDs, which contradicts the explicit legacy reconciliation path and compatibility obligation.
## Findings on this change (also posted as inline comments) (9)
In lib/data/store/migrations/m004_kv_to_tables.dart around line 68, address this finding:
The migration is not restart/idempotent across the commit/version-record boundary: after the transaction commits but before `SchemaVersion.migrate` stores v5, a crash leaves all consumed KV rows deleted while `serverOrder`/`snippetOrder` remains in `kv`. On the next launch `apply` rebuilds empty `serverIds` and `snippetNames`, then `_rewriteOrder` resolves every existing entry to null and overwrites both order lists with `[]`, losing the user's ordering (and any still-valid setting entries). The claim is false only if the version write is guaranteed atomic with the SQLite transaction, but it is a separate `_store(v + 1)` operation after `await step.apply()` and uses a different store path.
In lib/data/store/migrations/m004_kv_to_tables.dart around line 150, address this finding:
Duplicate legacy private-key ids are not handled safely: `_migratePrivateKeys` inserts each duplicate as a distinct row but assigns `ids[oldId] = id` repeatedly, so every server/reference using that old id is silently remapped to whichever duplicate happened to be processed last. If duplicate ids are instead duplicate names represented by different rows, the migration preserves both key blobs but loses the identity of all references to the earlier one. This is disproved only if the v4 format guarantees globally unique key ids for all historical data; the migration's own comment says uniqueness was not enforced.
In lib/data/store/migrations/m004_kv_to_tables.dart around line 77, address this finding:
Unreadable or non-object source rows are silently made unrecoverable. `_raw` catches JSON decode errors and `_rows` skips non-map values, but apply later unconditionally deletes every row in each consumed store. For example, one truncated `server` JSON value is logged and omitted, all other servers migrate, and `DELETE FROM kv WHERE store = 'server'` erases the truncated record; a later retry or manual recovery cannot recover it. The same applies to malformed rows in keys, snippets, port forwards, docker, conn_stat, and agent_conversation.
In lib/data/store/entity_store.dart around line 178, address this finding:
Deleting a server also leaves PortForwardStore's cache containing rows that SQLite has already cascaded away, so a backup made after the deletion can resurrect those deleted forwards.
In lib/data/store/container.dart around line 164, address this finding:
A newer remote snapshot cannot delete per-server container settings: `BackupV2.merge` delegates each `container` entry to `ContainerStore.restoreOne`, but `restoreOne` only upserts hosts/runtime and never removes rows absent from the incoming object. For example, device A deletes a server's Docker host (and its server timestamp advances), while device B still has the host; B merges A's newer backup, retains the host, and `put`/`setType` also stamps the server again, so the next upload can resurrect the supposedly deleted setting on A. This is introduced by the v5 table-backed container restore path; it would be disproved only if container deletion is explicitly intended to be non-synchronizable, contrary to the store comments and the parent-server timestamp design.
In test/hive_release_migration_test.dart around line 74, address this finding:
The release-fixture suite never exercises a release install whose data boxes are plain (or mixed plain/encrypted). `hive_release_migration_test.dart` copies only the checked-in `*_enc.hive` files, and `hive_import_test.dart` creates every data box through `HiveStore`, which also produces encrypted files; its only plain file is the deliberately special `conn_stats_index.hive`. This leaves the compatibility branch that detects `$name.hive` and imports it untested: a regression in plain-box discovery/opening could make old pre-encryption installs look fresh and silently lose their data while all current tests pass. This gap is introduced by the new fixture-based coverage because the fixtures are uniformly encrypted except for the index. It would be disproved if a permanent test copied/constructed each supported box as plain (including a mixed plain/encrypted set) and verified the same full import and second-launch behavior.
In lib/main.dart around line 243, address this finding:
Newer-schema refusal happens after several writes, so a downgraded build is not read-only while it is supposed to preserve the newer data. `Stores.init` runs setting fixups (`removeRetiredKeys`, SSH mode/home-tab migrations) and can run Hive import before `_doDbMigrate`; `_doDbMigrate` itself updates feature settings before calling `SchemaVersion.migrate`. With a stored schema version above the supported version, those writes occur and only then does `SchemaTooNewException` stop the launch. The claim would be false only if all these preflight writes were proven absent for a newer-schema database, but they are unconditional/flag-driven initialization paths.
In lib/data/model/app/bak/backup2.dart around line 77, address this finding:
BackupV2 restore is not atomic across stores despite the restore contract requiring a coherent backup. `merge` commits key, server, snippet, port-forward, and container changes in separate store operations, then launches history/settings merges separately; a process kill or exception after (for example) server replacement but before settings/history leaves a partially restored backup with no rollback. The claim would be false only if all these store operations shared one SQLite transaction, but each EntityStore/SqliteStore operation commits independently and the `Future.wait` is explicitly separate.
In test/hive_release_migration_test.dart around line 400, address this finding:
The permanent release test does not assert all rows in the v1491 agent-conversation box. The fixture generator writes both `conv-1` (for `srv-key`) and `conv-2` (for `srv-pwd`), plus an active pointer for `srv-key`, but the test only fetches `srv-key` and checks one conversation/one active pointer. A decoder or migration that silently drops every conversation for another server, or drops the `srv-pwd` row, would still pass; this violates the fixture/complete-path assertion requirement. This finding is disproved only if another permanent test enumerates and validates `conv-2` and the corresponding active state.
## Additional findings on this change (not posted inline) (23)
In lib/data/store/migrations/m003_hive_to_sqlite.dart around line 116, address this finding:
An install containing only the legacy plaintext `conn_stats_index.hive` is treated as a fresh install and the plaintext file is left behind. `runIfNeeded` builds `present` only from `_boxes` (which intentionally excludes `conn_stats_index`); when that list is empty it returns through `SchemaVersion.initFresh()` without calling `_dropPlaintextIndex`. The tests cover an entirely empty directory and an index alongside all normal boxes, but not the empty-legacy-box-list/index-only variant, so this data-protection cleanup regression is currently undetected. The claim would be false if another startup path independently deletes the index before this code runs, or if an index-only install is intentionally outside the supported legacy states.
In lib/data/store/migrations/m004_kv_to_tables.dart around line 211, address this finding:
Duplicate legacy server identities abort the entire migration instead of being handled. If two kv/server rows have the same non-empty `v['id']` (or a generated empty-id happens to collide), both are converted to that id and the second `INSERT INTO server` violates the primary key. Because apply is retried at v4 after rollback, the same malformed/duplicate input fails on every launch; no records are migrated and the user cannot reach v5. The same unguarded behavior exists for duplicate port-forward ids at its INSERT.
In lib/data/store/migrations/m004_kv_to_tables.dart around line 176, address this finding:
A syntactically valid JSON object with a malformed field can brick the migration rather than be skipped or dropped. For example, a legacy server row with `"ssh":"corrupt"` reaches `v['ssh'] as Map?` and throws a cast error (similarly `tags` as a non-list, `envs` as a non-map, or `jumpIds` as a non-list). The transaction rolls back, SchemaVersion remains v4, and the same row throws on every launch; unlike `_rows`'s JSON-level catch, there is no per-record validation boundary.
In lib/data/store/migrations/m004_kv_to_tables.dart around line 139, address this finding:
KvToTablesMigration does not actually skip malformed record maps; it skips only non-map rows, then uses unchecked casts while migrating each map. For example a corrupted key row such as `{ "private_key": 42 }` reaches `_migratePrivateKeys`, where `(row.value['private_key'] ?? row.value['key']) as String?` throws a TypeError. Because `apply` wraps the whole operation in one transaction, that one record aborts migration and prevents all otherwise valid records from being migrated, contrary to the per-record malformed-data compatibility promise.
In lib/data/store/migrations/m003_hive_to_sqlite.dart around line 157, address this finding:
The plaintext connection-stat index is not reliably removed. `present` deliberately excludes `conn_stats_index`, so an install containing only that legacy file is treated as a fresh install and returns from `runIfNeeded` without calling `_dropPlaintextIndex`. Also, when any encrypted box is unread, the method returns before cleanup, and when deletion itself fails `_dropPlaintextIndex` only logs the error before writing the permanent import marker. Thus a stale `<documents>/conn_stats_index.hive` can remain readable indefinitely, contrary to the migration's encryption invariant, including after a successful retry or on platforms where the file is temporarily undeletable. This is false only if the index is guaranteed to coexist with a recognized box and deletion is guaranteed to succeed before the marker is persisted.
In lib/data/store/migrations/m004_kv_to_tables.dart around line 581, address this finding:
Orphaned agent conversations are retained and can be made active instead of being dropped. The only non-server scope is the explicit global sentinel `__global_agent__`, but this code maps any unknown `serverId` with `serverIds[serverId] ?? serverId` and likewise any unknown `active::` scope with `serverIds[scope] ?? scope`. Thus a conversation belonging to a deleted/malformed server remains under its stale id, and its active row is recreated; it is then visible to `fetchForServer(staleId)` and consumes the local conversation quota despite having no owning server. This would be disproved only if every unknown scope in the legacy box is guaranteed to be the global sentinel, which is incompatible with the server-scoped storage format and the migration's stated orphan-cleanup rule.
In test/hive_import_test.dart around line 101, address this finding:
The migration tests never exercise a legacy data box that exists only as `<name>.hive` (the pre-encryption variant). `HiveImport.runIfNeeded` explicitly promises to detect and import either `<name>_enc.hive` or `<name>.hive`, but `seedHive()` creates boxes through `HiveStore` (encrypted), and the release test copies only `_enc` fixtures; its added plain `snippet.hive` is an empty directory used to force an open failure while `snippet_enc.hive` remains the actual data source, not a plain-data import. Consequently a regression in the plain-file discovery/open path can pass all permanent tests. This is disproved only if another permanent migration test seeds real records in a plain legacy box and runs the full import.
In lib/data/store/migrations/m004_kv_to_tables.dart around line 173, address this finding:
The v4→v5 migration is not recoverable when legacy KV contains duplicate server IDs: `_migrateServers` inserts each row's `v['id']` directly as the new primary key, without deduplicating or skipping collisions. Two legacy records under different KV keys can carry the same non-empty `id`; the second INSERT then raises a SQLite UNIQUE/PRIMARY KEY exception, aborting the transaction, while `SchemaVersion` remains v4. Every subsequent launch retries the same failing migration, so the app cannot reach the v5 layout or expose the data for repair. This is especially relevant because the migration already claims to tolerate/drop malformed legacy records, but this collision path is fatal.
In lib/data/store/migrations/m003_hive_to_sqlite.dart around line 72, address this finding:
The migration drops the legacy per-record modification timestamps for every entity. `_intoKvTable` writes every imported row with `updated_at = 0`; m004 merely copies that zero into `private_key`, `server`, `snippet`, and `port_forward`. Any legacy timestamp metadata row is skipped by `_raw` because it uses the internal prefix filter, so it cannot be used to populate those columns. Consequently an install with existing Hive sync history upgrades with all entity rows looking unchanged/older (`Stores.lastModTime` and per-record timestamps are zero), and equal-timestamp merge logic can fail to propagate an actual newer local record or deletion. This would be false only if the released Hive layout never stored per-record modification metadata and zero timestamps were explicitly the intended compatibility semantics.
In lib/view/page/private_key/edit.dart around line 75, address this finding:
The private-key editor can write to disposed controllers after navigation away while asynchronous clipboard/file loading is still in flight.
In lib/view/page/private_key/edit.dart around line 79, address this finding:
If the user leaves this page before Clipboard.getData or the file picker/read completes, the continuation still assigns _keyController.text even though dispose() has already disposed that controller, producing an uncaught disposed-controller error. The claim is false only if every one of these asynchronous operations is guaranteed to complete before route disposal, which Flutter's clipboard/file APIs do not guarantee.
In lib/view/page/private_key/edit.dart around line 303, address this finding:
When decryptPem or a durable key write fails (other than DuplicateNameException), _onTapSave catches it, displays a toast, and then rethrows from an async-void callback. This turns ordinary wrong-password/read/write failures into uncaught asynchronous errors; the claim is false only if the application intentionally has a top-level policy that treats every such rethrow as a handled UI error, which is not present in this handler.
In test/file_tab_restore_test.dart around line 116, address this finding:
The positive file-tab restore tests are false-green: they preload the expected JSON, pump the page, then assert only that the store still contains the same JSON, so a no-op restore (or one that never opens `/tmp/somewhere`/`/var/log`) passes.
In pubspec.yaml around line 7, address this finding:
The declared SDK floor does not match the resolved dependency graph: `pubspec.yaml` permits Dart 3.11 (`sdk: ">=3.11.0"`), while the checked-in `pubspec.lock` records `sdks.dart: ">=3.12.0 <4.0.0"`. A release or CI job using Dart/Flutter with Dart 3.11 can therefore fail dependency resolution before the Drift/sqlite3mc build hook runs, despite satisfying this package's manifest. This is false only if the project’s supported toolchain is separately guaranteed to be Dart >=3.12 and the manifest floor is intentionally unused.
In docs/src/content/docs/development/architecture.md around line 40, address this finding:
The English and Chinese architecture pages do not satisfy the documented database/test contract: they describe ownership and migration steps but omit the required startup order (`SqliteStore.openDatabase` → `createTables` → store init → `HiveImport` → app migration) and the in-memory test lifecycle (`openTestDb`, foreign-key pragma, `forTest`, and `SqliteDb.close` teardown). They also state that all models use Freezed with built-in JSON serialization, while the repository guidance explicitly documents exceptions such as hand-written `PortForwardConfig.toJson` and frozen legacy adapters. A contributor following the architecture page can therefore initialize stores before the schema or create file-backed widget-test databases, and can incorrectly add current model adapters to the legacy import path.
In docs/src/content/docs/development/architecture.md around line 107, address this finding:
The architecture documentation omits the mandatory in-memory database lifecycle for widget/store tests. The repository's test helper opens an in-memory connection, enables the per-connection foreign-key pragma, creates the Drift schema, and every caller must close `SqliteDb` in tearDown and use each store's `forTest()` instance to avoid singleton list-cache leakage; the current test suite demonstrates this pattern. Without documenting it, a new table-backed widget test can use the normal singleton/file-backed store, leave writes pending in Flutter's fake-async zone, and hang teardown or leak cached rows into later tests. This would be false if the architecture documentation contained an equivalent test-lifecycle section, but neither language page mentions `openTestDb`, `SqliteDb.close`, `forTest`, or the fake-async/file-write hazard.
In lib/data/store/migrations/m004_kv_to_tables.dart, address this finding:
A malformed but valid-JSON object in a legacy entity row can abort the entire v4-to-v5 migration instead of being skipped, leaving the database at v4 and causing the same failure on every retry.
In docs/src/content/docs/development/testing.md around line 125, address this finding:
The migration documentation still references the deleted `test/hive_v1466_migration_test.dart` and presents the old single-fixture workflow as the active test matrix.
In test/ssh_tab_restore_test.dart around line 111, address this finding:
The main SSH restore test does not establish that either restored tab was actually opened. It writes two entries, pumps, then asserts that the store still contains the two original entries and their tmux windows; a broken `_restoreTabs` that returned without calling `_open` would satisfy that assertion. The only `SSHPage` assertion in this file is for the separate server/local selection case, so the central two-tab restoration behavior is not exercised by the test.
In docs/src/content/docs/development/architecture.md around line 83, address this finding:
The architecture documentation does not state the startup ordering that makes the storage migration safe, so it omits a critical schema ownership invariant. `Stores.init` must open the SQLite handle, create Drift's tables, initialize KV stores, import Hive, and only then run `SchemaVersion.migrate` before providers are loaded; `HiveImport` itself is not a substitute for the later v5 table migration. The current architecture page only lists the two migration names and their transformations, without this ordering or the fact that `main.dart` deliberately runs `_doDbMigrate` before `runApp`. A contributor following the page could initialize/read entity stores before `createTables` or run m004 before m003, yielding missing-table failures or stranded rows. This finding would be false if another architecture section explicitly documented and linked this exact order, but neither the English nor Chinese page does.
In lib/data/store/migrations/m003_hive_to_sqlite.dart, address this finding:
When an encrypted legacy box is temporarily unreadable, the import returns before removing the plaintext connection-stat index. The `unread` early-return path calls `_setDoneBoxes` and `initAtHiveImport` but never `_dropPlaintextIndex`; if keychain access never recovers, every launch keeps the plaintext index beside the new database indefinitely. Even when recovery eventually succeeds, the sensitive artifact remains during the whole retry window.
In test/fixtures/README.md, address this finding:
The checked-in fixture tests do not provide an enforceable provenance check that the binary bytes came from the tagged releases. The generator programs are `.dart.txt` recipes and the release test only verifies filenames, encryption, and selected decoded values; it never compares fixture bytes against a reproducible output/hash or otherwise proves that the checked-in files were generated by the corresponding release worktree. Thus a fixture regenerated with the current adapters (or hand-edited to match the selected assertions) can pass, defeating the permanent regression test's requirement that it be fed bytes the migrated-from release actually wrote. This would be disproved if CI or the test suite regenerated each fixture using the release tag's generator/adapters and compared the resulting bytes (or checked in a verifiable provenance/hash manifest).
In docs/src/content/docs/development/architecture.md, address this finding:
The architecture pages make a false blanket claim that all data models use Freezed and have built-in JSON serialization. `lib/data/model/server/port_forward.dart` contains the explicitly exceptional `PortForwardStatus` class, and `PortForwardConfig` has no generated `.g.dart`; its hand-written `toJson` is required because KV encoding otherwise returns failure and silently drops port forwards. The docs therefore omit a generated-code/storage contract that is important to this migration and could lead a maintainer to remove the manual serializer or assume regeneration is sufficient. This would be false if the documentation qualified the claim or documented this exception elsewhere on the architecture page, but it currently does not.
## Previously reported and still present (5)
In lib/data/store/entity_store.dart around line 240, address this finding:
The per-store caches and change streams are not invalidated when another store causes a foreign-key cascade or SET NULL. For example, after PortForwardStore.fetch() caches a forward, ServerStore.deleteById() deletes the server and cascades port_forward, but only ServerStore.invalidate() runs; the port-forward store continues returning the deleted object and emits no watch event. Likewise deleting a private key SET NULLs server.ssh_key_id without invalidating ServerStore, and deleting a server removes SnippetStore auto-run children without invalidating SnippetStore. This violates cache freshness and public reader/notification behavior; it would be false only if all such cascaded tables were guaranteed never to have been cached or observed between the writes.
In lib/data/store/migrations/m003_hive_to_sqlite.dart around line 139, address this finding:
If every recognized encrypted box fails to open, the app does not have a retryable startup state: `done` stays empty, `SchemaVersion` retains its default v2, and `_doDbMigrate` is called after `Stores.init` with only a v4→v5 migration. `SchemaVersion.migrate` therefore throws `StateError('Missing schema migration from v2 to v3')` before the app starts. A locked device whose keychain is unavailable for all Hive boxes can hit exactly this path; even though `runIfNeeded` logs that the boxes are left for the next launch, the launch fails before becoming usable. This is false only if the default schema version is guaranteed to be v4 for all such SQLite databases or the caller skips schema migration while unread boxes remain.
In lib/data/model/app/bak/backup2.dart around line 81, address this finding:
BackupV2 container restoration applies stale values unconditionally, cannot propagate child-field deletions, and stamps restored data as a new local edit.
In lib/data/store/entity_store.dart around line 245, address this finding:
Deleting a server leaves sync-root port forwards without tombstones, so the deletion cannot converge across devices.
In test/hive_release_migration_test.dart, address this finding:
The permanent fixture assertions depend on wall-clock time while the generated stats have a fixed timestamp of 2026-01-01. On an initial launch within 30 days of that timestamp, the second-launch assertion expects `conn_stat` to be empty even though `ConnectionStatsStore._expire` must retain those rows; on a run sufficiently after that date, the first-launch 120-row assertion can instead be affected by the sweep if setup/order changes. Thus the test is not stable over its intended permanent lifetime and does not reliably prove the second-launch behavior. This is disproved only if the test pins the clock or the fixture timestamp is guaranteed older than the retention window in every supported test run.

Duplicate legacy private-key ids are not handled safely: `_migratePrivateKeys` inserts each duplicate as a distinct row but assigns `ids[oldId] = id` repeatedly, so every server/reference using that old id is silently remapped to whichever duplicate happened to be processed last. If duplicate ids are instead duplicate names represented by different rows, the migration preserves both key blobs but loses the identity of all references to the earlier one. This is disproved only if the v4 format guarantees globally unique key ids for all historical data; the migration's own comment says uniqueness was not enforced.

⚠️ The malformed or non-object value would generally require pre-existing corruption, an older bug, or externally modified database data; however, the migration path for any such existing row is directly confirmed.

In lib/data/store/migrations/m004_kv_to_tables.dart, address this finding:
Unreadable or non-object source rows are silently made unrecoverable. `_raw` catches JSON decode errors and `_rows` skips non-map values, but apply later unconditionally deletes every row in each consumed store. For example, one truncated `server` JSON value is logged and omitted, all other servers migrate, and `DELETE FROM kv WHERE store = 'server'` erases the truncated record; a later retry or manual recovery cannot recover it. The same applies to malformed rows in keys, snippets, port forwards, docker, conn_stat, and agent_conversation.

In lib/data/store/container.dart, address this finding:
A newer remote snapshot cannot delete per-server container settings: `BackupV2.merge` delegates each `container` entry to `ContainerStore.restoreOne`, but `restoreOne` only upserts hosts/runtime and never removes rows absent from the incoming object. For example, device A deletes a server's Docker host (and its server timestamp advances), while device B still has the host; B merges A's newer backup, retains the host, and `put`/`setType` also stamps the server again, so the next upload can resurrect the supposedly deleted setting on A. This is introduced by the v5 table-backed container restore path; it would be disproved only if container deletion is explicitly intended to be non-synchronizable, contrary to the store comments and the parent-server timestamp design.

⚠️ The exact set of historical releases that wrote all data boxes without encryption is not established from the repository; however, the claimed missing plain-box and mixed-box coverage is directly established by the fixture names and test setup.
🤖 Prompt for AI agents
In test/hive_release_migration_test.dart, address this finding:
The release-fixture suite never exercises a release install whose data boxes are plain (or mixed plain/encrypted). `hive_release_migration_test.dart` copies only the checked-in `*_enc.hive` files, and `hive_import_test.dart` creates every data box through `HiveStore`, which also produces encrypted files; its only plain file is the deliberately special `conn_stats_index.hive`. This leaves the compatibility branch that detects `$name.hive` and imports it untested: a regression in plain-box discovery/opening could make old pre-encryption installs look fresh and silently lose their data while all current tests pass. This gap is introduced by the new fixture-based coverage because the fixtures are uniformly encrypted except for the index. It would be disproved if a permanent test copied/constructed each supported box as plain (including a mixed plain/encrypted set) and verified the same full import and second-launch behavior.

In lib/main.dart, address this finding:
Newer-schema refusal happens after several writes, so a downgraded build is not read-only while it is supposed to preserve the newer data. `Stores.init` runs setting fixups (`removeRetiredKeys`, SSH mode/home-tab migrations) and can run Hive import before `_doDbMigrate`; `_doDbMigrate` itself updates feature settings before calling `SchemaVersion.migrate`. With a stored schema version above the supported version, those writes occur and only then does `SchemaTooNewException` stop the launch. The claim would be false only if all these preflight writes were proven absent for a newer-schema database, but they are unconditional/flag-driven initialization paths.

BackupV2 restore is not atomic across stores despite the restore contract requiring a coherent backup. `merge` commits key, server, snippet, port-forward, and container changes in separate store operations, then launches history/settings merges separately; a process kill or exception after (for example) server replacement but before settings/history leaves a partially restored backup with no rollback. The claim would be false only if all these store operations shared one SQLite transaction, but each EntityStore/SqliteStore operation commits independently and the `Future.wait` is explicitly separate.

⚠️ The repository does not show an explicit formal requirement for the exact number of assertions, but no other permanent test enumerates the v1491 fixture's srv-pwd conversation.
🤖 Prompt for AI agents
In test/hive_release_migration_test.dart, address this finding:
The permanent release test does not assert all rows in the v1491 agent-conversation box. The fixture generator writes both `conv-1` (for `srv-key`) and `conv-2` (for `srv-pwd`), plus an active pointer for `srv-key`, but the test only fetches `srv-key` and checks one conversation/one active pointer. A decoder or migration that silently drops every conversation for another server, or drops the `srv-pwd` row, would still pass; this violates the fixture/complete-path assertion requirement. This finding is disproved only if another permanent test enumerates and validates `conv-2` and the corresponding active state.
…load m004 remapped `agent_conversation.server_id` when a server's id was regenerated, but re-encoded the original JSON beside it. The store rebuilds a conversation from `data` and then compares `conversation.serverId` against the server it was asked about — `fetchActive`, `setActive` and `deleteConversation` all do — so the column found the record and every one of those three rejected it. The conversation existed and nothing could reach it. `test/m004_id_remap_test.dart` covers the rule the bug broke: a server stored before 1155 has an empty id and lives under `user@ip:port`, so the migration generates one, and everything naming the old key has to follow in the same pass. Six cases — the id itself, agent conversations in both places, snippet auto-run targets, port forwards, container hosts and `serverOrder`. Checked against a reverted fix: the conversation case fails without it. 1050/1050 passing.

The seed in `m004_id_remap_test` was a claim from memory about what `HiveImport` leaves for a pre-1155 server. Four such claims in this branch turned out wrong, each silently dropping a whole store, so it should not be one. Not by feeding that test release bytes: m004 does not consume any. Its input is what m003 leaves in `kv`, which is this repo's own intermediate — release bytes are m003's input, and `hive_release_migration_test` already runs all three fixtures through both steps. Instead the one fact the seed rests on is asserted there, against 1466/1480/1491: a server from before 1155 reaches `kv` with `id == ''` and an `ssh` map, and it is the only record that does. The seed cannot drift from a real upgrade without that failing. Verified by probe before writing it, rather than assumed again. 1053/1053 passing.

🔎 Confirmed findings (7)
- 🟠 High m004 is not restart-safe after its SQL transaction commits but before SchemaVersion advances: a retry can erase the already-rewritten order lists. For example, if the process dies after the transaction deletes
kv/serverbut before_store(5), the next run has an emptyserverIdsmap, yet_rewriteOrder('serverOrder', ...)still sees the old order and rewrites every entry to null, leavingserverOrderas[](and similarlysnippetOrder). Thus a crash in the documented retry window loses the user's ordering even though the entity rows survived. (inline) - 🟠 High BackupV2.merge is not atomic. It commits key, server, snippet, port-forward, and container changes before the separately awaited history/settings merges, and each entity merge has its own transaction. A process kill, database error, or failure while restoring a later store therefore leaves a partially restored backup (for example keys and servers from the backup but old snippets/port forwards/settings), with no rollback or marker that the restore was incomplete. This violates whole-backup restore semantics and differs from Backup.merge, which explicitly wraps the whole restore in one transaction. (inline)
- 🟠 High m004 is not tolerant of duplicate/invalid legacy server records: two
kv/serverrows can carry the same non-empty internalid(or a generated ID can collide), and_migrateServersexecutes a plainINSERT INTO serverfor each without deduplication or per-record recovery. SQLite raises the primary-key constraint inside the outer transaction, aborting the entire migration and leaving schema version at v4, so the app cannot complete startup on that installation. The migration's stated invalid-record policy only drops SSH/monitor-invalid rows and does not cover duplicate IDs. (inline) - 🟠 High BackupV2 cannot restore legacy name-keyed server records without losing their identity and dependent references. A pre-table backup can carry a server under its old storage/name key with an empty
id;Spi.fromJsongenerates a fresh ID, whileServerStoredoes not overridereconcileand the map key is discarded. Consequentlyssh.jumpIds, snippetautoRunOn, container entries, and port-forwardserverIdvalues that still name the old server do not match the newly generated row and are dropped or left dangling during merge. (inline) - 🟠 High BackupV2 applies container children outside the server record's last-write-wins decision, so an older backup can overwrite newer local server configuration.
Stores.server.mergeskips an incoming server when its timestamp is not newer, but the following unconditionalStores.container.restoreOnestill upserts the backup's host/runtime and stamps the server; a stale restore therefore changes the server despite its newerupdated_at. The reverse case also leaves deleted child settings behind: when a newer backup has no container entry,restoreOnedoes nothing and never removes the local host/runtime. This is disproven only if container data is intentionally excluded from server merge semantics and is guaranteed never to be deleted or conflict independently. (inline) - 🟡 Medium Deleting a server leaves a stale PortForwardStore cache populated with forwards that SQLite has already cascaded away. (inline)
- 🟡 Medium The schema accepts invalid port-forward port numbers even though the store and restore write them directly and readers treat them as usable configuration. (inline)
⛔ Unresolved from previous review (19) — not approved until fixed
- lib/data/store/container.dart: A newer remote snapshot cannot delete per-server container settings:
BackupV2.mergedelegates eachcontainerentry toContainerStore.restoreOne, butrestoreOneonly upserts hosts/runtime and never removes rows absent from the incoming object. For example, device A deletes a server's Docker host (and its server timestamp advances), while device B still has the host; B merges A's newer backup, retains the host, andput/setTypealso stamps the server again, so the next upload can resurrect the supposedly deleted setting on A. This is introduced by the v5 table-backed container restore path; it would be disproved only if container deletion is explicitly intended to be non-synchronizable, contrary to the store comments and the parent-server timestamp design. - lib/data/store/entity_store.dart: Deleting a server also leaves PortForwardStore's cache containing rows that SQLite has already cascaded away, so a backup made after the deletion can resurrect those deleted forwards.
- lib/data/store/migrations/m004_kv_to_tables.dart: KvToTablesMigration does not actually skip malformed record maps; it skips only non-map rows, then uses unchecked casts while migrating each map. For example a corrupted key row such as
{ "private_key": 42 }reaches_migratePrivateKeys, where(row.value['private_key'] ?? row.value['key']) as String?throws a TypeError. Becauseapplywraps the whole operation in one transaction, that one record aborts migration and prevents all otherwise valid records from being migrated, contrary to the per-record malformed-data compatibility promise. — The current_rowsmethod still admits any JSON object without validating field types, and_migratePrivateKeysstill performs the unchecked cast(row.value['private_key'] ?? row.value['key']) as String?. A map containingprivate_key: 42therefore still throws during the transaction and can abort migration instead of being skipped per record. - lib/data/model/app/bak/backup2.dart: BackupV2 restores container settings without applying the backup's timestamps or force/non-force deletion semantics.
restoreOnecallsContainerStore.put/setType, which stamps the owning server with the current local time, and it never removes host/runtime rows absent from the backup. Thus an older non-forced backup can overwrite a newer server's container host, and a forced restore can leave stale container settings that the backup deleted; the restore also makes the server look like a fresh local edit instead of preserving the incoming timestamp. This would be false only if container settings are intentionally excluded from restore conflict/deletion semantics and are guaranteed never to be changed by restore, which is contradicted byBackupV2.loadFromStoreincluding them andrestoreOnewriting them. - lib/data/store/migrations/m004_kv_to_tables.dart: A syntactically valid JSON object with a malformed field can brick the migration rather than be skipped or dropped. For example, a legacy server row with
"ssh":"corrupt"reachesv['ssh'] as Map?and throws a cast error (similarlytagsas a non-list,envsas a non-map, orjumpIdsas a non-list). The transaction rolls back, SchemaVersion remains v4, and the same row throws on every launch; unlike_rows's JSON-level catch, there is no per-record validation boundary. — The migration still processes each decoded server object without a per-record try/catch. In_migrateServers,final ssh = v['ssh'] as Map?;still throws for a valid JSON object whosesshis a string, and the lateras List?/as Map?casts fortags,envs, andssh['jumpIds']likewise remain uncaught. That exception aborts the transaction, so the malformed row can still prevent SchemaVersion from advancing and recur on launch. - lib/data/store/migrations/m004_kv_to_tables.dart: Duplicate legacy server identities abort the entire migration instead of being handled. If two kv/server rows have the same non-empty
v['id'](or a generated empty-id happens to collide), both are converted to that id and the secondINSERT INTO serverviolates the primary key. Because apply is retried at v4 after rollback, the same malformed/duplicate input fails on every launch; no records are migrated and the user cannot reach v5. The same unguarded behavior exists for duplicate port-forward ids at its INSERT. — The migration still derives each non-empty stored id directly and executes a plain INSERT for every server row. There is no uniqueness check, remapping, or conflict handling before this insert, so two rows with the same id still raise a PRIMARY KEY constraint error and abort the transaction. Port forwards likewise still use a plain INSERT with their legacy id, so duplicate port-forward ids remain able to abort migration. - lib/data/store/migrations/m004_kv_to_tables.dart: Unreadable or non-object source rows are silently made unrecoverable.
_rawcatches JSON decode errors and_rowsskips non-map values, but apply later unconditionally deletes every row in each consumed store. For example, one truncatedserverJSON value is logged and omitted, all other servers migrate, andDELETE FROM kv WHERE store = 'server'erases the truncated record; a later retry or manual recovery cannot recover it. The same applies to malformed rows in keys, snippets, port forwards, docker, conn_stat, and agent_conversation. — The migration still decodes rows in_rawinside a catch and_rowsstill skips values that are not maps, butapply()subsequently unconditionally executesDELETE FROM kv WHERE store = ?for every store in_consumed. Therefore an unreadable or non-object row can still be logged/skipped and then erased along with successfully migrated rows, preventing retry or manual recovery. - lib/data/store/migrations/m004_kv_to_tables.dart: The migration is not restart/idempotent across the commit/version-record boundary: after the transaction commits but before
SchemaVersion.migratestores v5, a crash leaves all consumed KV rows deleted whileserverOrder/snippetOrderremains inkv. On the next launchapplyrebuilds emptyserverIdsandsnippetNames, then_rewriteOrderresolves every existing entry to null and overwrites both order lists with[], losing the user's ordering (and any still-valid setting entries). The claim is false only if the version write is guaranteed atomic with the SQLite transaction, but it is a separate_store(v + 1)operation afterawait step.apply()and uses a different store path. — The migration still commits its SQLite work insideSqliteStore.transact, whileSchemaVersion.migraterecords v5 only afterward via the separate_store(v + 1)call. If the process crashes in that interval, the next run sees the consumed stores missing, leavesserverIdsandsnippetNamesempty, and the current_rewriteOrdercalls resolve every surviving order entry to null before updating the settings to[]. Thus the reported loss of ordering can still occur. - lib/data/store/migrations/m003_hive_to_sqlite.dart: Malformed JSON-shaped records are not isolated per record in m004: unchecked casts such as
v['name'] as String?,v['ssh'] as Map?, and nested field casts occur after_rowsaccepts any Map, so one malformed server/key/snippet row throws inside the single transaction, rolls back all conversions, and causes the same failure on every launch rather than dropping or recording that bad row while migrating the rest. - lib/data/store/migrations/m003_hive_to_sqlite.dart: An install containing only the legacy plaintext
conn_stats_index.hiveis treated as a fresh install and the plaintext file is left behind.runIfNeededbuildspresentonly from_boxes(which intentionally excludesconn_stats_index); when that list is empty it returns throughSchemaVersion.initFresh()without calling_dropPlaintextIndex. The tests cover an entirely empty directory and an index alongside all normal boxes, but not the empty-legacy-box-list/index-only variant, so this data-protection cleanup regression is currently undetected. The claim would be false if another startup path independently deletes the index before this code runs, or if an index-only install is intentionally outside the supported legacy states. - lib/data/store/entity_store.dart: Deleting a server leaves live port-forward provider state inconsistent with the relational database.
- Deleting a private key changes the referencing server (
ssh_key_idbecomes NULL) without updating that server's sync metadata or clearing/replacing its cache. The schema's ON DELETE SET NULL fires inside the raw DELETE, but no ServerStore.touch/stamp is called; the key store only tombstones the key. Thus incremental sync can miss the server's credential change, and a cached ServerStore can continue returning a Spi with the deleted key ID until another server-store write invalidates it. This is false only if every private-key deletion caller separately stamps and invalidates ServerStore, but the schema test and the key store's own delete path provide no such trigger. — The private-key deletion path still only performs the generic entity delete:EntityStore.deleteByIddeletes the key row, tombstonesprivate_key, and invalidates only that store's cache. The schema still usesON DELETE SET NULLforserver.ssh_key_id, but there is no correspondingServerStore.touchor server-cache invalidation.PrivateKeyNotifier.deletecallsStores.key.delete(info)directly, so deleting a referenced key can still leave the cached server with the old key ID and leaveserver.updated_at/revunchanged for incremental sync. - lib/data/store/tables.dart: Trusted SSH host fingerprints are migrated into the new
known_hosttable, but that table is absent fromTables.syncRootsandBackupV2has no field or merge path for it. After an upgrade,m004deletes the oldsetting/sshKnownHostFingerprintscopy, so the fingerprints are neither included in subsequent backups/sync nor restored on another device;trustHostonly stamps the server and cannot make the child rows travel. - lib/data/store/entity_store.dart: Entity-store sync can lose a newer edit when two edits occur in the same millisecond, despite the new schema's
revtie-breaker.SyncedTable.stampincrementsrev, butEntityStore.timestampsexports onlyupdated_at;EntityStore.mergecompares only those timestamps and skips when the incoming timestamp is<=the local timestamp. Thus a peer backup containing the later revision with the same millisecond timestamp is treated as stale and is never written. — The defect is still present:timestampsexports onlyupdated_atfor each row, andmergeobtains only those timestamp values via_timestampsOfand skips a known incoming record when(bakTs ?? 0) <= (current[id] ?? 0). AlthoughSyncedTable.stampincrements the databaserev, that revision is neither included in the backup metadata nor used as a tie-breaker, so a later edit with the same millisecond timestamp can still be discarded. - lib/data/store/agent_conversation.dart: Saving a non-active conversation can delete the currently active conversation without selecting a replacement. With 30 conversations for a server and the active row pointing to the oldest one,
save(..., setActive: false)upserts a 31st row and_pruneServerdeletes the oldest row; the FK cascade removesagent_active_conversation, sofetchActivebecomes null even though 29 older/newer conversations remain. This changes active-selection behavior and violates the compound-write invariant for saves that do not explicitly change selection. It would be false only if callers guarantee that the active conversation is never the row pruned by a setActive:false save, but the store API and generic rename/save path do not enforce that. - A downgrade/future-schema install is not rejected before startup mutates its data.
_initDatacompletesStores.init()before_doDbMigrate()performs theSchemaTooNewExceptioncheck, and_doDbMigrateitself runsautoAddNewCards,autoAddNewFuncs, and writeslastVerbefore callingSchemaVersion.migrate. Thus a build supporting v5 opening a database marked v6 can rewrite settings (and, if the import marker is absent while legacy boxes remain,HiveImport.runIfNeededcan also copy legacy rows and reset the stored schema to v4) before eventually refusing or migrating it. A newer build can consequently lose future-build settings or have future data mixed with old imported data instead of getting a clean, recoverable downgrade failure. This is disproven only if all future-version databases are guaranteed to have the import marker and all pre-fixup settings already in exactly the shape that makes every pre-migration write a no-op; the ordering still permits those writes for a valid future database with stale/missing feature keys. — The downgrade can still mutate data before the future-schema check._initDatastill awaitsStores.init()first;Stores.init()opens/creates the database, initializes stores, runsHiveImport.runIfNeeded(), removes retired keys, and performs setting migrations before returning. Then_doDbMigrate()readslastVerand can still callautoAddNewCards,autoAddNewFuncs, and writelastVerbeforeSchemaVersion.migrate()checksfrom > currentand throws. Therefore a database marked with a future schema can still be rewritten (including legacy import/reset behavior) before rejection. - Future-schema refusal occurs after startup has already initialized stores and run writes: Stores.init runs connectionStats.init and HiveImport.runIfNeeded, then removes retired keys and performs setting migrations before SchemaVersion.migrate checks
stored > current;_doDbMigratealso applies app fixups and writes lastVer before that check. A downgrade can therefore sweep/delete data or rewrite settings (and in an incomplete Hive-import state can import/version data) before refusing the newer schema, violating fail-closed downgrade protection. — The downgrade guard is still reached only after startup-side writes:_initDatastill executesawait Stores.init()before_doDbMigrate, andStores.initstill runsconnectionStats.init(),HiveImport.runIfNeeded(),removeRetiredKeys(), and setting migrations. In_doDbMigrate, app fixups andlastVer.put(newVer)still precedeSchemaVersion.migrate; although the schema check itself now refusesstored > current, a future-schema launch can therefore still sweep/import/delete/rewrite data before that refusal. - lib/data/store/migrations/m003_hive_to_sqlite.dart: A partially successful Hive import can permanently regress the schema version and cause m004 to run twice against already-migrated rows. For example, if the key box imports but the server box is temporarily unreadable,
runIfNeededrecords v4 as soon as any box is done; the next launch can run m004 and record v5, but when the pending server box later imports, the all-boxes-success path callsinitAtHiveImport()again and sets the version back to v4. The following launch reruns m004 even though the first run deleted the consumed kv stores and inserted rows into the entity tables, so its plain INSERTs hit primary/unique conflicts (or generate duplicate-renamed keys) and startup migration fails/data is duplicated. This is false only if the import/version update is guaranteed never to complete a pending box after m004 has committed, or if version writes are atomically coupled to the import and migration transaction. - lib/data/store/entity_store.dart: EntityStore.merge compares timestamps using the incoming serialized ID before applying reconcile(), so legacy name-keyed snippet backups can overwrite a newer local snippet. A pre-ID backup decodes to a fresh generated ID;
currentcontains the local generated ID,incoming[id]has no timestamp for the fresh ID, and the loop accepts the record.SnippetStore.reconcile()then maps it by name onto the existing local ID and write() replaces the newer row/children. The per-record timestamp must be resolved by stable name before the LWW comparison. This is false only if all supported backups always contain stable IDs, which contradicts the explicit legacy reconciliation path and compatibility obligation. — The merge still performs the LWW decision in the serialized-ID loop before reconciliation:bakTsis read asincoming[id]andknownascurrent.containsKey(id), whilereconcile(item)is only called afterward. For a legacy name-keyed snippet, decoding can produce a fresh ID, so the existing local row is not recognized during the timestamp check; reconciliation then maps the incoming item onto the local ID andwrite(resolved)can replace it despite the newer local timestamp.
⚠️ Unverified risks (3)
- m004 does not isolate malformed individual legacy records: several casts and structural accesses occur outside a per-row try/catch, so one semantically malformed JSON object aborts the whole transaction and prevents unrelated records from migrating. For example, a server row with
sshencoded as a scalar reachesfinal ssh = v['ssh'] as Map?and throws; a malformedenvs,custom, port-forward numeric field, or duplicate/conflicting destination id can similarly throw. Because the transaction rolls back and the source kv rows remain, every launch retries the same bad row and unrelated valid rows never complete, contrary to the obligation to skip unsupported individual records. This would be disproven only if upstream guarantees every kv row has the exact expected object shapes and unique destination identities. (lib/data/store/migrations/m004_kv_to_tables.dart) - The plaintext connection-stats index is not deleted for an index-only legacy install (and remains while any encrypted box is unreadable).
presentis built only from_boxes, which deliberately excludesconn_stats_index; if the only legacy artifact isconn_stats_index.hive/.lock,present.isEmptytakes the fresh-install return before_dropPlaintextIndex. Likewise, an unreadable pending box returns before cleanup. Thus a successful-looking fresh initialization or a permanently locked/corrupt import can leave server IDs and timestamps in plaintext indefinitely, contrary to the migration's stated plaintext-removal invariant. (lib/data/store/migrations/m003_hive_to_sqlite.dart) - A malformed/orphan record in a legacy backup can cause unrelated valid local records to be lost even though the restore claims to skip invalid records.
Backup.mergecallsreplaceAll, which first tombstones and deletes the entire table, then catchesSqliteExceptionper incoming item and continues. If the backup has one server with a missing private-key FK (or a CHECK violation) and another valid server, the invalid server is skipped but the pre-existing local server rows have already been deleted and the transaction still commits; the user is left with neither the old local copy nor the skipped backup record. The same destructive pattern applies to keys/snippets/other entity stores. (lib/data/store/entity_store.dart)
📋 Additional findings from this change (not shown inline) (19)
- 🟠 High A box containing an unreadable individual record is marked complete even though its contents were only partially copied, so that record is never retried.
_importBoxcatches a per-record decode/JSON failure, continues, and still returnsopened: true;runIfNeededadds the box to_done, and a fully opened set then writes the global import marker. The retained Hive rollback file cannot help normal startup because the marker prevents any future read. (lib/data/store/migrations/m003_hive_to_sqlite.dart) — anchor-outside-diff - 🟠 High Encrypted remote parse/decryption failures are not marked as unsafe remote data, so after fromFile fails the base sync flow can still execute its unconditional upload and overwrite the unreadable encrypted payload with this device's copy. (lib/core/sync.dart) — anchor-unreliable
- 🟠 High A failed read of an encrypted remote backup can still cause the base sync cycle to overwrite that remote with this device's local backup.
fromFileonly records_remoteTooNewforSchemaTooNewException; whenCryptor.decryptfails (wrong/missing password, damaged encrypted payload, or a password rotation), the broad catch retries the no-password reader, which also fails, and rethrows a non-schema exception. The inheritedSyncIfacecycle is documented here as catching merge/read failures and then uploading unconditionally, whilebackuponly vetoes the schema-too-new flag. Thus an encrypted remote that this device cannot decrypt is treated as an ordinary parse failure and is replaced by the local copy. This is disproven only if the actualSyncIface._syncimplementation aborts without callingbackupfor non-schemafromFilefailures (contrary to the lifecycle contract relied on by this change). (lib/core/sync.dart) — anchor-unreliable - 🟠 High An encrypted remote backup that cannot be parsed can still be overwritten by this device.
fromFilecatches every exception from the password-aware reader (including wrong password, decryption failure, malformed ciphertext, and encrypted payloads whose JSON cannot be decoded), logs it, and retries the same content through the unencrypted reader. If that retry also throws,fromFilepropagates without setting_remoteTooNew; the baseSyncIfacelifecycle then catches the read/merge failure and proceeds to its unconditional upload, whilebackupallows the upload because the guard only checks_remoteTooNew. A device with an incorrect/stale backup password or a corrupt encrypted remote file can therefore replace the only remote copy with its local data. (lib/core/sync.dart) — anchor-outside-diff - 🟠 High A local or remote forwarding connection can be added after provider disposal/disconnect has already finished closing the entry, so its socket/channel is never included in the close snapshot and leaks. (lib/data/provider/port_forward_provider.dart) — anchor-outside-diff
- 🟠 High The upload guard does not cover merge failures, so a remote payload that parses successfully but fails while being applied is still replaced by the local snapshot.
backuponly refuses when_remoteTooNewis set byfromFile;merge()never sets that flag, and the base lifecycle is explicitly described here as uploading after a caught merge failure. For example, a parsed backup can reach store application and throw from a transaction/SQLite write (or a legacy whole-store restore), after which the sync cycle uploads without having established that the remote state was safely incorporated. The remote data is preserved only when the failure happens to be classified asSchemaTooNewException; any other merge exception leaves the overwrite path open. (lib/core/sync.dart) — anchor-outside-diff - 🟠 High A newer-schema backup with a non-integer numeric version can be accepted instead of refused. (lib/data/model/app/bak/backup2.dart) — anchor-outside-diff
- 🟠 High BackupV2 restores container children additively and without the server's timestamp decision, so deleted or stale container settings can be resurrected.
ContainerStore.restoreOneonly callsput/setTypefor values present in the incoming map and never removes a locally existing host/runtime that is absent; moreoverBackupV2.mergeinvokes it after the independent server merge even when that server record was skipped as older. For example, device A deletes a server's container host (or changes it), device B has the old host, and B merges A's backup: the old host remains/resurrects because container data has no tombstone/timestamp and is not part of the server merge. This is related to the change because containers were moved under table-backed servers and documented as child state that must travel with the parent. (lib/data/model/app/bak/backup2.dart) — per-file-budget - 🟡 Medium Duplicate legacy private-key identities are not remapped consistently.
_migratePrivateKeysinserts a generated row for each record, but assignsids[oldId] = idon each iteration, so if two legacy rows have the same storedid/name (for example distinct Hive keys carrying the sameid), the map retains only the last generated id. Every server whosepubKeyIdnames that old identity is attached to the last key, while the earlier key remains inprivate_keywith no possible reference; iteration order therefore changes which credential a server uses. This violates the duplicate-key retention/reference requirement and would be disproven only if the released storage invariant guarantees no two records can ever carry the same old key identity. (lib/data/store/migrations/m004_kv_to_tables.dart) — per-file-budget - 🟡 Medium The
revcounter does not actually distinguish same-millisecond edits during backup merge.SyncedTable.stampincrementsrev, butEntityStore.timestampsexports onlyupdated_at, andmergecompares only those timestamps (bakTs <= current). If two devices edit the same record in one timestamp tick, the later merge treats the incoming edit as a tie and skips it, despite the schema/comment claiming rev prevents indistinguishable edits. (lib/data/store/entity_store.dart) — inline-budget - 🟡 Medium
_remoteTooNewis global to the singleton rather than scoped to the remote storage/file that produced it, and it is never cleared by legacy-inheritance failure or by a sync to an empty/different remote. For example, iCloud contains a newer v4 file,inheritLegacyRemote(or a sync) sets_remoteTooNew, then the user switches to WebDAV (or enables it while its versioned file is absent); that sync has nofromFilesuccess to reset the flag, so the overriddenbackupsilently returns and never creates the valid WebDAV copy. The same stale flag is left behind wheninheritLegacyRemotecatchesSchemaTooNewException. This is disproven only if the base lifecycle always invokesfromFilesuccessfully before everybackup, including empty remotes and remote-provider changes, which would make the flag effectively per-cycle rather than the static state shown here. (lib/core/sync.dart) — inline-budget - 🟡 Medium Port-forward stop/remove can return while a start is awaiting connection because both operations contend on the same per-ID _inFlight set; the later start then installs an active forward after the user has stopped or removed it. (lib/data/provider/port_forward_provider.dart) — anchor-unreliable
- 🟡 Medium A local or remote forwarding connection can be appended to an entry after close() snapshots and clears _connections, so disconnecting the server/client can leave that late-created socket/channel unclosed and the provider loses its handle. (lib/data/provider/port_forward_provider.dart) — anchor-unreliable
- 🟡 Medium Deleting a private key updates only the key provider/cache; the server provider and per-server notifier retain Spi objects whose ssh.keyId is now a deleted FK. A subsequent server save/reconnect can write that stale keyId and fail with a foreign-key error, while the UI still presents the deleted key reference. (lib/data/provider/private_key.dart) — inline-budget
- 🟡 Medium The declared
revmetadata does not participate in backup timestamps or merge ordering, so two edits within one millisecond are still lost despite the schema's stated invariant. (lib/data/store/entity_store.dart) — inline-budget - 🟡 Medium Container restore is not replacement-safe:
restoreOneonly writes hosts/runtime keys present in the incoming entry and never removes local rows absent from that entry, whileBackupV2.mergecalls it for incoming entries only. If a device removes a server's container host (or switches back to the default, causing the runtime row to be deleted) and syncs, a peer with the old host/runtime retains it because the backup has no deletion metadata and restoreOne does not clear it. The peer can then continue using configuration that was deleted on the source. (lib/data/store/container.dart) — inline-budget - 🟡 Medium A forced v1 restore does not actually replace all key-value sections:
_restoreIntoskips deletion of local keys absent from the backup when force is true, leaving stale history/settings entries despite the documented force-replace behavior. (lib/data/model/app/bak/backup.dart) — inline-budget - 🟡 Medium Deleting a server leaves dependent entity-store caches and provider state stale, so a backup or later UI edit can use relationships that the database has already cascaded away. For example, after
Stores.portForward.fetch()orStores.snippet.fetch()has populated its cache,delServeronly callsStores.server.deleteById(id); the SQL cascade removesport_forwardandsnippet_auto_run_on, but neither child store is invalidated.EntityStore.getAllMap()then serializes the stale cached objects, potentially uploading a deleted port-forward/auto-run relation to a peer that still has the server, and the snippet/forward UI can continue showing it until an unrelated write/reload. This would be false only if these stores are guaranteed never to be read before server deletion and no backup/UI read occurs before their caches are dropped. (lib/data/provider/server/all.dart) — inline-budget - 🟡 Medium The migration API documentation still describes every SchemaMigration as rewriting Hive stores in place, which is false for the shipped v5 migration and misstates the migration boundary. (lib/data/store/schema.dart) — anchor-unreliable
♻️ Previously reported (still present) (3)
- 🟠 High The insert logic is not restart-safe for an already partially migrated database. If
private_keyorserverrows have been committed while their source kv rows remain (the state the SchemaMigration contract explicitly requires apply() to tolerate), rerunning_migratePrivateKeys/_migrateServersuses plainINSERTwith newly generated ids and fails on the existing logical record (or on a duplicate source id), rolling back the current transaction and preventing the kv cleanup/version advance. The same issue exists for snippets, port forwards, stats, and other plain inserts. Atomic rollback protects an ordinary SQLite crash, but does not satisfy the documented “already partially migrated” precondition: an interrupted/externally restored state containing destination rows and unconsumed kv is a concrete retry scenario. This is false only if the migration framework can guarantee that destination tables are always empty whenever any consumed kv row exists, rather than merely guaranteeing atomicity of one invocation. (lib/data/store/migrations/m004_kv_to_tables.dart) — previously-reported - 🟠 High Private-key reconciliation can make a restored server fail its foreign-key write because references are not remapped to the reconciled key id. When the backup key has id
K1and this device already has the same key name under idK2,PrivateKeyStore.reconcilechanges the incoming key toK2;BackupV2.mergethen merges the server unchanged, withssh_key_id = K1. The server upsert violatesserver.ssh_key_id REFERENCES private_key(id), is caught and skipped, so the server (and its children) is not restored even though its key was successfully matched. This is disproven only if key ids are guaranteed globally stable across all backup-producing devices or same-name/different-id keys are guaranteed impossible. (lib/data/store/private_key.dart) — previously-reported - 🟠 High Stopping/removing/updating a forward while its start is still awaiting connection does not stop the eventual forward, leaving an orphan listener/SSH forward.

## Unresolved from the previous review — these block approval, fix them first (19)
In lib/data/store/container.dart, address this finding:
A newer remote snapshot cannot delete per-server container settings: `BackupV2.merge` delegates each `container` entry to `ContainerStore.restoreOne`, but `restoreOne` only upserts hosts/runtime and never removes rows absent from the incoming object. For example, device A deletes a server's Docker host (and its server timestamp advances), while device B still has the host; B merges A's newer backup, retains the host, and `put`/`setType` also stamps the server again, so the next upload can resurrect the supposedly deleted setting on A. This is introduced by the v5 table-backed container restore path; it would be disproved only if container deletion is explicitly intended to be non-synchronizable, contrary to the store comments and the parent-server timestamp design.
In lib/data/store/entity_store.dart, address this finding:
Deleting a server also leaves PortForwardStore's cache containing rows that SQLite has already cascaded away, so a backup made after the deletion can resurrect those deleted forwards.
In lib/data/store/migrations/m004_kv_to_tables.dart, address this finding:
KvToTablesMigration does not actually skip malformed record maps; it skips only non-map rows, then uses unchecked casts while migrating each map. For example a corrupted key row such as `{ "private_key": 42 }` reaches `_migratePrivateKeys`, where `(row.value['private_key'] ?? row.value['key']) as String?` throws a TypeError. Because `apply` wraps the whole operation in one transaction, that one record aborts migration and prevents all otherwise valid records from being migrated, contrary to the per-record malformed-data compatibility promise.
In lib/data/model/app/bak/backup2.dart, address this finding:
BackupV2 restores container settings without applying the backup's timestamps or force/non-force deletion semantics. `restoreOne` calls `ContainerStore.put`/`setType`, which stamps the owning server with the current local time, and it never removes host/runtime rows absent from the backup. Thus an older non-forced backup can overwrite a newer server's container host, and a forced restore can leave stale container settings that the backup deleted; the restore also makes the server look like a fresh local edit instead of preserving the incoming timestamp. This would be false only if container settings are intentionally excluded from restore conflict/deletion semantics and are guaranteed never to be changed by restore, which is contradicted by `BackupV2.loadFromStore` including them and `restoreOne` writing them.
In lib/data/store/migrations/m004_kv_to_tables.dart, address this finding:
A syntactically valid JSON object with a malformed field can brick the migration rather than be skipped or dropped. For example, a legacy server row with `"ssh":"corrupt"` reaches `v['ssh'] as Map?` and throws a cast error (similarly `tags` as a non-list, `envs` as a non-map, or `jumpIds` as a non-list). The transaction rolls back, SchemaVersion remains v4, and the same row throws on every launch; unlike `_rows`'s JSON-level catch, there is no per-record validation boundary.
In lib/data/store/migrations/m004_kv_to_tables.dart, address this finding:
Duplicate legacy server identities abort the entire migration instead of being handled. If two kv/server rows have the same non-empty `v['id']` (or a generated empty-id happens to collide), both are converted to that id and the second `INSERT INTO server` violates the primary key. Because apply is retried at v4 after rollback, the same malformed/duplicate input fails on every launch; no records are migrated and the user cannot reach v5. The same unguarded behavior exists for duplicate port-forward ids at its INSERT.
In lib/data/store/migrations/m004_kv_to_tables.dart, address this finding:
Unreadable or non-object source rows are silently made unrecoverable. `_raw` catches JSON decode errors and `_rows` skips non-map values, but apply later unconditionally deletes every row in each consumed store. For example, one truncated `server` JSON value is logged and omitted, all other servers migrate, and `DELETE FROM kv WHERE store = 'server'` erases the truncated record; a later retry or manual recovery cannot recover it. The same applies to malformed rows in keys, snippets, port forwards, docker, conn_stat, and agent_conversation.
In lib/data/store/migrations/m004_kv_to_tables.dart, address this finding:
The migration is not restart/idempotent across the commit/version-record boundary: after the transaction commits but before `SchemaVersion.migrate` stores v5, a crash leaves all consumed KV rows deleted while `serverOrder`/`snippetOrder` remains in `kv`. On the next launch `apply` rebuilds empty `serverIds` and `snippetNames`, then `_rewriteOrder` resolves every existing entry to null and overwrites both order lists with `[]`, losing the user's ordering (and any still-valid setting entries). The claim is false only if the version write is guaranteed atomic with the SQLite transaction, but it is a separate `_store(v + 1)` operation after `await step.apply()` and uses a different store path.
In lib/data/store/migrations/m003_hive_to_sqlite.dart, address this finding:
Malformed JSON-shaped records are not isolated per record in m004: unchecked casts such as `v['name'] as String?`, `v['ssh'] as Map?`, and nested field casts occur after `_rows` accepts any Map, so one malformed server/key/snippet row throws inside the single transaction, rolls back all conversions, and causes the same failure on every launch rather than dropping or recording that bad row while migrating the rest.
In lib/data/store/migrations/m003_hive_to_sqlite.dart, address this finding:
An install containing only the legacy plaintext `conn_stats_index.hive` is treated as a fresh install and the plaintext file is left behind. `runIfNeeded` builds `present` only from `_boxes` (which intentionally excludes `conn_stats_index`); when that list is empty it returns through `SchemaVersion.initFresh()` without calling `_dropPlaintextIndex`. The tests cover an entirely empty directory and an index alongside all normal boxes, but not the empty-legacy-box-list/index-only variant, so this data-protection cleanup regression is currently undetected. The claim would be false if another startup path independently deletes the index before this code runs, or if an index-only install is intentionally outside the supported legacy states.
In lib/data/store/entity_store.dart, address this finding:
Deleting a server leaves live port-forward provider state inconsistent with the relational database.
Somewhere in the code under review, address this finding:
Deleting a private key changes the referencing server (`ssh_key_id` becomes NULL) without updating that server's sync metadata or clearing/replacing its cache. The schema's ON DELETE SET NULL fires inside the raw DELETE, but no ServerStore.touch/stamp is called; the key store only tombstones the key. Thus incremental sync can miss the server's credential change, and a cached ServerStore can continue returning a Spi with the deleted key ID until another server-store write invalidates it. This is false only if every private-key deletion caller separately stamps and invalidates ServerStore, but the schema test and the key store's own delete path provide no such trigger.
In lib/data/store/tables.dart, address this finding:
Trusted SSH host fingerprints are migrated into the new `known_host` table, but that table is absent from `Tables.syncRoots` and `BackupV2` has no field or merge path for it. After an upgrade, `m004` deletes the old `setting/sshKnownHostFingerprints` copy, so the fingerprints are neither included in subsequent backups/sync nor restored on another device; `trustHost` only stamps the server and cannot make the child rows travel.
In lib/data/store/entity_store.dart, address this finding:
Entity-store sync can lose a newer edit when two edits occur in the same millisecond, despite the new schema's `rev` tie-breaker. `SyncedTable.stamp` increments `rev`, but `EntityStore.timestamps` exports only `updated_at`; `EntityStore.merge` compares only those timestamps and skips when the incoming timestamp is `<=` the local timestamp. Thus a peer backup containing the later revision with the same millisecond timestamp is treated as stale and is never written.
In lib/data/store/agent_conversation.dart, address this finding:
Saving a non-active conversation can delete the currently active conversation without selecting a replacement. With 30 conversations for a server and the active row pointing to the oldest one, `save(..., setActive: false)` upserts a 31st row and `_pruneServer` deletes the oldest row; the FK cascade removes `agent_active_conversation`, so `fetchActive` becomes null even though 29 older/newer conversations remain. This changes active-selection behavior and violates the compound-write invariant for saves that do not explicitly change selection. It would be false only if callers guarantee that the active conversation is never the row pruned by a setActive:false save, but the store API and generic rename/save path do not enforce that.
Somewhere in the code under review, address this finding:
A downgrade/future-schema install is not rejected before startup mutates its data. `_initData` completes `Stores.init()` before `_doDbMigrate()` performs the `SchemaTooNewException` check, and `_doDbMigrate` itself runs `autoAddNewCards`, `autoAddNewFuncs`, and writes `lastVer` before calling `SchemaVersion.migrate`. Thus a build supporting v5 opening a database marked v6 can rewrite settings (and, if the import marker is absent while legacy boxes remain, `HiveImport.runIfNeeded` can also copy legacy rows and reset the stored schema to v4) before eventually refusing or migrating it. A newer build can consequently lose future-build settings or have future data mixed with old imported data instead of getting a clean, recoverable downgrade failure. This is disproven only if all future-version databases are guaranteed to have the import marker and all pre-fixup settings already in exactly the shape that makes every pre-migration write a no-op; the ordering still permits those writes for a valid future database with stale/missing feature keys.
Somewhere in the code under review, address this finding:
Future-schema refusal occurs after startup has already initialized stores and run writes: Stores.init runs connectionStats.init and HiveImport.runIfNeeded, then removes retired keys and performs setting migrations before SchemaVersion.migrate checks `stored > current`; `_doDbMigrate` also applies app fixups and writes lastVer before that check. A downgrade can therefore sweep/delete data or rewrite settings (and in an incomplete Hive-import state can import/version data) before refusing the newer schema, violating fail-closed downgrade protection.
In lib/data/store/migrations/m003_hive_to_sqlite.dart, address this finding:
A partially successful Hive import can permanently regress the schema version and cause m004 to run twice against already-migrated rows. For example, if the key box imports but the server box is temporarily unreadable, `runIfNeeded` records v4 as soon as any box is done; the next launch can run m004 and record v5, but when the pending server box later imports, the all-boxes-success path calls `initAtHiveImport()` again and sets the version back to v4. The following launch reruns m004 even though the first run deleted the consumed kv stores and inserted rows into the entity tables, so its plain INSERTs hit primary/unique conflicts (or generate duplicate-renamed keys) and startup migration fails/data is duplicated. This is false only if the import/version update is guaranteed never to complete a pending box after m004 has committed, or if version writes are atomically coupled to the import and migration transaction.
In lib/data/store/entity_store.dart, address this finding:
EntityStore.merge compares timestamps using the incoming serialized ID before applying reconcile(), so legacy name-keyed snippet backups can overwrite a newer local snippet. A pre-ID backup decodes to a fresh generated ID; `current` contains the local generated ID, `incoming[id]` has no timestamp for the fresh ID, and the loop accepts the record. `SnippetStore.reconcile()` then maps it by name onto the existing local ID and write() replaces the newer row/children. The per-record timestamp must be resolved by stable name before the LWW comparison. This is false only if all supported backups always contain stable IDs, which contradicts the explicit legacy reconciliation path and compatibility obligation.
## Findings on this change (also posted as inline comments) (7)
In lib/data/store/migrations/m004_kv_to_tables.dart around line 68, address this finding:
m004 is not restart-safe after its SQL transaction commits but before SchemaVersion advances: a retry can erase the already-rewritten order lists. For example, if the process dies after the transaction deletes `kv/server` but before `_store(5)`, the next run has an empty `serverIds` map, yet `_rewriteOrder('serverOrder', ...)` still sees the old order and rewrites every entry to null, leaving `serverOrder` as `[]` (and similarly `snippetOrder`). Thus a crash in the documented retry window loses the user's ordering even though the entity rows survived.
In lib/data/model/app/bak/backup2.dart around line 77, address this finding:
BackupV2.merge is not atomic. It commits key, server, snippet, port-forward, and container changes before the separately awaited history/settings merges, and each entity merge has its own transaction. A process kill, database error, or failure while restoring a later store therefore leaves a partially restored backup (for example keys and servers from the backup but old snippets/port forwards/settings), with no rollback or marker that the restore was incomplete. This violates whole-backup restore semantics and differs from Backup.merge, which explicitly wraps the whole restore in one transaction.
In lib/data/store/migrations/m004_kv_to_tables.dart around line 211, address this finding:
m004 is not tolerant of duplicate/invalid legacy server records: two `kv/server` rows can carry the same non-empty internal `id` (or a generated ID can collide), and `_migrateServers` executes a plain `INSERT INTO server` for each without deduplication or per-record recovery. SQLite raises the primary-key constraint inside the outer transaction, aborting the entire migration and leaving schema version at v4, so the app cannot complete startup on that installation. The migration's stated invalid-record policy only drops SSH/monitor-invalid rows and does not cover duplicate IDs.
In lib/data/store/server.dart around line 17, address this finding:
BackupV2 cannot restore legacy name-keyed server records without losing their identity and dependent references. A pre-table backup can carry a server under its old storage/name key with an empty `id`; `Spi.fromJson` generates a fresh ID, while `ServerStore` does not override `reconcile` and the map key is discarded. Consequently `ssh.jumpIds`, snippet `autoRunOn`, container entries, and port-forward `serverId` values that still name the old server do not match the newly generated row and are dropped or left dangling during merge.
In lib/data/model/app/bak/backup2.dart around line 83, address this finding:
BackupV2 applies container children outside the server record's last-write-wins decision, so an older backup can overwrite newer local server configuration. `Stores.server.merge` skips an incoming server when its timestamp is not newer, but the following unconditional `Stores.container.restoreOne` still upserts the backup's host/runtime and stamps the server; a stale restore therefore changes the server despite its newer `updated_at`. The reverse case also leaves deleted child settings behind: when a newer backup has no container entry, `restoreOne` does nothing and never removes the local host/runtime. This is disproven only if container data is intentionally excluded from server merge semantics and is guaranteed never to be deleted or conflict independently.
In lib/data/store/entity_store.dart around line 240, address this finding:
Deleting a server leaves a stale PortForwardStore cache populated with forwards that SQLite has already cascaded away.
In lib/data/store/db.dart around line 262, address this finding:
The schema accepts invalid port-forward port numbers even though the store and restore write them directly and readers treat them as usable configuration.
## Additional findings on this change (not posted inline) (19)
In lib/data/store/migrations/m003_hive_to_sqlite.dart around line 135, address this finding:
A box containing an unreadable individual record is marked complete even though its contents were only partially copied, so that record is never retried. `_importBox` catches a per-record decode/JSON failure, continues, and still returns `opened: true`; `runIfNeeded` adds the box to `_done`, and a fully opened set then writes the global import marker. The retained Hive rollback file cannot help normal startup because the marker prevents any future read.
In lib/core/sync.dart, address this finding:
Encrypted remote parse/decryption failures are not marked as unsafe remote data, so after fromFile fails the base sync flow can still execute its unconditional upload and overwrite the unreadable encrypted payload with this device's copy.
In lib/core/sync.dart, address this finding:
A failed read of an encrypted remote backup can still cause the base sync cycle to overwrite that remote with this device's local backup. `fromFile` only records `_remoteTooNew` for `SchemaTooNewException`; when `Cryptor.decrypt` fails (wrong/missing password, damaged encrypted payload, or a password rotation), the broad catch retries the no-password reader, which also fails, and rethrows a non-schema exception. The inherited `SyncIface` cycle is documented here as catching merge/read failures and then uploading unconditionally, while `backup` only vetoes the schema-too-new flag. Thus an encrypted remote that this device cannot decrypt is treated as an ordinary parse failure and is replaced by the local copy. This is disproven only if the actual `SyncIface._sync` implementation aborts without calling `backup` for non-schema `fromFile` failures (contrary to the lifecycle contract relied on by this change).
In lib/core/sync.dart around line 72, address this finding:
An encrypted remote backup that cannot be parsed can still be overwritten by this device. `fromFile` catches every exception from the password-aware reader (including wrong password, decryption failure, malformed ciphertext, and encrypted payloads whose JSON cannot be decoded), logs it, and retries the same content through the unencrypted reader. If that retry also throws, `fromFile` propagates without setting `_remoteTooNew`; the base `SyncIface` lifecycle then catches the read/merge failure and proceeds to its unconditional upload, while `backup` allows the upload because the guard only checks `_remoteTooNew`. A device with an incorrect/stale backup password or a corrupt encrypted remote file can therefore replace the only remote copy with its local data.
In lib/data/provider/port_forward_provider.dart around line 257, address this finding:
A local or remote forwarding connection can be added after provider disposal/disconnect has already finished closing the entry, so its socket/channel is never included in the close snapshot and leaks.
In lib/core/sync.dart around line 107, address this finding:
The upload guard does not cover merge failures, so a remote payload that parses successfully but fails while being applied is still replaced by the local snapshot. `backup` only refuses when `_remoteTooNew` is set by `fromFile`; `merge()` never sets that flag, and the base lifecycle is explicitly described here as uploading after a caught merge failure. For example, a parsed backup can reach store application and throw from a transaction/SQLite write (or a legacy whole-store restore), after which the sync cycle uploads without having established that the remote state was safely incorporated. The remote data is preserved only when the failure happens to be classified as `SchemaTooNewException`; any other merge exception leaves the overwrite path open.
In lib/data/model/app/bak/backup2.dart around line 164, address this finding:
A newer-schema backup with a non-integer numeric version can be accepted instead of refused.
In lib/data/model/app/bak/backup2.dart around line 81, address this finding:
BackupV2 restores container children additively and without the server's timestamp decision, so deleted or stale container settings can be resurrected. `ContainerStore.restoreOne` only calls `put`/`setType` for values present in the incoming map and never removes a locally existing host/runtime that is absent; moreover `BackupV2.merge` invokes it after the independent server merge even when that server record was skipped as older. For example, device A deletes a server's container host (or changes it), device B has the old host, and B merges A's backup: the old host remains/resurrects because container data has no tombstone/timestamp and is not part of the server merge. This is related to the change because containers were moved under table-backed servers and documented as child state that must travel with the parent.
In lib/data/store/migrations/m004_kv_to_tables.dart around line 150, address this finding:
Duplicate legacy private-key identities are not remapped consistently. `_migratePrivateKeys` inserts a generated row for each record, but assigns `ids[oldId] = id` on each iteration, so if two legacy rows have the same stored `id`/name (for example distinct Hive keys carrying the same `id`), the map retains only the last generated id. Every server whose `pubKeyId` names that old identity is attached to the last key, while the earlier key remains in `private_key` with no possible reference; iteration order therefore changes which credential a server uses. This violates the duplicate-key retention/reference requirement and would be disproven only if the released storage invariant guarantees no two records can ever carry the same old key identity.
In lib/data/store/entity_store.dart around line 330, address this finding:
The `rev` counter does not actually distinguish same-millisecond edits during backup merge. `SyncedTable.stamp` increments `rev`, but `EntityStore.timestamps` exports only `updated_at`, and `merge` compares only those timestamps (`bakTs <= current`). If two devices edit the same record in one timestamp tick, the later merge treats the incoming edit as a tie and skips it, despite the schema/comment claiming rev prevents indistinguishable edits.
In lib/core/sync.dart around line 29, address this finding:
`_remoteTooNew` is global to the singleton rather than scoped to the remote storage/file that produced it, and it is never cleared by legacy-inheritance failure or by a sync to an empty/different remote. For example, iCloud contains a newer v4 file, `inheritLegacyRemote` (or a sync) sets `_remoteTooNew`, then the user switches to WebDAV (or enables it while its versioned file is absent); that sync has no `fromFile` success to reset the flag, so the overridden `backup` silently returns and never creates the valid WebDAV copy. The same stale flag is left behind when `inheritLegacyRemote` catches `SchemaTooNewException`. This is disproven only if the base lifecycle always invokes `fromFile` successfully before every `backup`, including empty remotes and remote-provider changes, which would make the flag effectively per-cycle rather than the static state shown here.
In lib/data/provider/port_forward_provider.dart, address this finding:
Port-forward stop/remove can return while a start is awaiting connection because both operations contend on the same per-ID _inFlight set; the later start then installs an active forward after the user has stopped or removed it.
In lib/data/provider/port_forward_provider.dart, address this finding:
A local or remote forwarding connection can be appended to an entry after close() snapshots and clears _connections, so disconnecting the server/client can leave that late-created socket/channel unclosed and the provider loses its handle.
In lib/data/provider/private_key.dart around line 45, address this finding:
Deleting a private key updates only the key provider/cache; the server provider and per-server notifier retain Spi objects whose ssh.keyId is now a deleted FK. A subsequent server save/reconnect can write that stale keyId and fail with a foreign-key error, while the UI still presents the deleted key reference.
In lib/data/store/entity_store.dart around line 279, address this finding:
The declared `rev` metadata does not participate in backup timestamps or merge ordering, so two edits within one millisecond are still lost despite the schema's stated invariant.
In lib/data/store/container.dart around line 164, address this finding:
Container restore is not replacement-safe: `restoreOne` only writes hosts/runtime keys present in the incoming entry and never removes local rows absent from that entry, while `BackupV2.merge` calls it for incoming entries only. If a device removes a server's container host (or switches back to the default, causing the runtime row to be deleted) and syncs, a peer with the old host/runtime retains it because the backup has no deletion metadata and restoreOne does not clear it. The peer can then continue using configuration that was deleted on the source.
In lib/data/model/app/bak/backup.dart around line 112, address this finding:
A forced v1 restore does not actually replace all key-value sections: `_restoreInto` skips deletion of local keys absent from the backup when force is true, leaving stale history/settings entries despite the documented force-replace behavior.
In lib/data/provider/server/all.dart around line 305, address this finding:
Deleting a server leaves dependent entity-store caches and provider state stale, so a backup or later UI edit can use relationships that the database has already cascaded away. For example, after `Stores.portForward.fetch()` or `Stores.snippet.fetch()` has populated its cache, `delServer` only calls `Stores.server.deleteById(id)`; the SQL cascade removes `port_forward` and `snippet_auto_run_on`, but neither child store is invalidated. `EntityStore.getAllMap()` then serializes the stale cached objects, potentially uploading a deleted port-forward/auto-run relation to a peer that still has the server, and the snippet/forward UI can continue showing it until an unrelated write/reload. This would be false only if these stores are guaranteed never to be read before server deletion and no backup/UI read occurs before their caches are dropped.
In lib/data/store/schema.dart, address this finding:
The migration API documentation still describes every SchemaMigration as rewriting Hive stores in place, which is false for the shipped v5 migration and misstates the migration boundary.
## Previously reported and still present (3)
In lib/data/store/migrations/m004_kv_to_tables.dart around line 152, address this finding:
The insert logic is not restart-safe for an already partially migrated database. If `private_key` or `server` rows have been committed while their source kv rows remain (the state the SchemaMigration contract explicitly requires apply() to tolerate), rerunning `_migratePrivateKeys`/`_migrateServers` uses plain `INSERT` with newly generated ids and fails on the existing logical record (or on a duplicate source id), rolling back the current transaction and preventing the kv cleanup/version advance. The same issue exists for snippets, port forwards, stats, and other plain inserts. Atomic rollback protects an ordinary SQLite crash, but does not satisfy the documented “already partially migrated” precondition: an interrupted/externally restored state containing destination rows and unconsumed kv is a concrete retry scenario. This is false only if the migration framework can guarantee that destination tables are always empty whenever any consumed kv row exists, rather than merely guaranteeing atomicity of one invocation.
In lib/data/store/private_key.dart around line 69, address this finding:
Private-key reconciliation can make a restored server fail its foreign-key write because references are not remapped to the reconciled key id. When the backup key has id `K1` and this device already has the same key name under id `K2`, `PrivateKeyStore.reconcile` changes the incoming key to `K2`; `BackupV2.merge` then merges the server unchanged, with `ssh_key_id = K1`. The server upsert violates `server.ssh_key_id REFERENCES private_key(id)`, is caught and skipped, so the server (and its children) is not restored even though its key was successfully matched. This is disproven only if key ids are guaranteed globally stable across all backup-producing devices or same-name/different-id keys are guaranteed impossible.
In lib/data/provider/port_forward_provider.dart around line 202, address this finding:
Stopping/removing/updating a forward while its start is still awaiting connection does not stop the eventual forward, leaving an orphan listener/SSH forward.

In lib/data/store/migrations/m004_kv_to_tables.dart, address this finding:
m004 is not restart-safe after its SQL transaction commits but before SchemaVersion advances: a retry can erase the already-rewritten order lists. For example, if the process dies after the transaction deletes `kv/server` but before `_store(5)`, the next run has an empty `serverIds` map, yet `_rewriteOrder('serverOrder', ...)` still sees the old order and rewrites every entry to null, leaving `serverOrder` as `[]` (and similarly `snippetOrder`). Thus a crash in the documented retry window loses the user's ordering even though the entity rows survived.

BackupV2.merge is not atomic. It commits key, server, snippet, port-forward, and container changes before the separately awaited history/settings merges, and each entity merge has its own transaction. A process kill, database error, or failure while restoring a later store therefore leaves a partially restored backup (for example keys and servers from the backup but old snippets/port forwards/settings), with no rollback or marker that the restore was incomplete. This violates whole-backup restore semantics and differs from Backup.merge, which explicitly wraps the whole restore in one transaction.

m004 is not tolerant of duplicate/invalid legacy server records: two `kv/server` rows can carry the same non-empty internal `id` (or a generated ID can collide), and `_migrateServers` executes a plain `INSERT INTO server` for each without deduplication or per-record recovery. SQLite raises the primary-key constraint inside the outer transaction, aborting the entire migration and leaving schema version at v4, so the app cannot complete startup on that installation. The migration's stated invalid-record policy only drops SSH/monitor-invalid rows and does not cover duplicate IDs.

- 🟠 High Legacy servers with both SSH and monitor credentials are silently dropped by the migration, violating lossless compatibility.
_migrateServerstreatshasSsh == hasMonitoras unrepresentable and skips the row; the prior model could store both andSpi.toJsoncan carry both. Upgrading such an installation removes the server and all of its nested data rather than preserving it or reporting a recoverable conflict. (inline) - 🟠 High Container settings are not merged losslessly: restoring a newer server state cannot remove a host/runtime child that is absent from the backup, and an older container payload is applied even when the corresponding server record is rejected by LWW. For example, device A deletes a server's Docker host (or changes its runtime), then merges a backup containing the older server/container data;
BackupV2.mergeappliesrestoreOneto every container entry unconditionally, whilerestoreOneonly inserts values that are present and never deletes missinghost_*orruntimerows. The deleted/changed child therefore remains locally and can continue to affect connections after the server merge. This is introduced by the new child-table backup path; it would be false only if container entries were guaranteed to be complete, timestamped, and filtered against the server merge before this method is called. (inline) - 🟠 High A BackupV2 merge is not atomic across the relational roots and dependent sections. The entity stores commit each
mergeindependently, then container writes commit independently, while history/settings are launched in a separateFuture.wait; if a later section fails (for example a malformed or constraint-invalid history/settings entry, or an interrupted process), keys/servers/snippets/port forwards and possibly container state have already been committed. This violates the restore invariant that a failed merge must not leave partial relational state; only the legacyBackup.mergeuses one transaction for the whole restore. (inline) - 🟡 Medium A backup merge that changes only container settings does not notify/reload the server provider, so the UI can keep showing stale server data until an unrelated server reload.
restoreOnemutates the child tables and callsStores.server.invalidate(), butBackupV2.mergeonly explicitly reloadsserversProviderwhenserversChangedis true; it does not use the server store change stream to reload the provider. Since container settings are deliberately represented as children of a server, this is a stale notification/cache path for exactly the settings that were moved into the relational schema. It would be false only if every consumer of server/container data independently listens to the store stream and rebuilds, but the merge code's explicit provider reload is the apparent notification boundary.

- lib/core/sync.dart: The upload guard does not cover merge failures, so a remote payload that parses successfully but fails while being applied is still replaced by the local snapshot.
backuponly refuses when_remoteTooNewis set byfromFile;merge()never sets that flag, and the base lifecycle is explicitly described here as uploading after a caught merge failure. For example, a parsed backup can reach store application and throw from a transaction/SQLite write (or a legacy whole-store restore), after which the sync cycle uploads without having established that the remote state was safely incorporated. The remote data is preserved only when the failure happens to be classified asSchemaTooNewException; any other merge exception leaves the overwrite path open. - lib/data/store/migrations/m004_kv_to_tables.dart: m004 is not tolerant of duplicate/invalid legacy server records: two
kv/serverrows can carry the same non-empty internalid(or a generated ID can collide), and_migrateServersexecutes a plainINSERT INTO serverfor each without deduplication or per-record recovery.

- lib/data/provider/port_forward_provider.dart: The migration tests never exercise a legacy data box that exists only as
<name>.hive(the pre-encryption variant).HiveImport.runIfNeededexplicitly promises to detect and import either<name>_enc.hiveor<name>.hive, butseedHive()creates boxes throughHiveStore(encrypted), and the release test copies only_encfixtures; its added plainsnippet.hiveis an empty directory used to force an open failure whilesnippet_enc.hiveremains the actual data source, not a plain-data import. Consequently a regression in the plain-file discovery/open path can pass all permanent tests. This is disproved only if another permanent migration test seeds real records in a plain legacy box and runs the full import. - lib/data/store/private_key.dart: Newer-schema refusal happens after several writes, so a downgraded build is not read-only while it is supposed to preserve the newer data.
Stores.initruns setting fixups (removeRetiredKeys, SSH mode/home-tab migrations) and can run Hive import before_doDbMigrate;_doDbMigrateitself updates feature settings before callingSchemaVersion.migrate. With a stored schema version above the supported version, those writes occur and only then doesSchemaTooNewExceptionstop the launch. The claim would be false only if all these preflight writes were proven absent for a newer-schema database, but they are unconditional/flag-driven initialization paths. - A failed read of an encrypted remote backup can still cause the base sync cycle to overwrite that remote with this device's local backup.
fromFileonly records_remoteTooNewforSchemaTooNewException; whenCryptor.decryptfails (wrong/missing password, damaged encrypted payload, or a password rotation), the broad catch retries the no-password reader, which also fails, and rethrows a non-schema exception. The inheritedSyncIfacecycle is documented here as catching merge/read failures and then uploading unconditionally, whilebackuponly vetoes the schema-too-new flag. Thus an encrypted remote that this device cannot decrypt is treated as an ordinary parse failure and is replaced by the local copy. This is disproven only if the actualSyncIface._syncimplementation aborts without callingbackupfor non-schemafromFilefailures (contrary to the lifecycle contract relied on by this change). — The defect remains inlib/core/sync.dart:fromFilerecords_remoteTooNewonly in theon SchemaTooNewExceptionbranch. A decryption or other encrypted-payload failure enters the broadcatch, retriesMergeableUtils.fromJsonString(content)without a password, and rethrows if that retry also fails;_remoteTooNewis still null. The overriddenbackupthen callssuper.backup(rs), so the failed remote read can still be followed by an upload of the local backup. - Encrypted remote parse/decryption failures are not marked as unsafe remote data, so after fromFile fails the base sync flow can still execute its unconditional upload and overwrite the unreadable encrypted payload with this device's copy. — The defect remains for encrypted parse/decryption failures.
fromFileonly sets_remoteTooNewin theSchemaTooNewExceptionbranch; a wrong password or other encrypted-payload failure enters the generic catch and then the passwordless fallback, which can still throw while leaving_remoteTooNewnull. The overriddenbackuptherefore proceeds tosuper.backup(rs)after that failed read, preserving the overwrite path. - lib/data/model/app/bak/backup2.dart: BackupV2.merge is not atomic. It commits key, server, snippet, port-forward, and container changes before the separately awaited history/settings merges, and each entity merge has its own transaction. A process kill, database error, or failure while restoring a later store therefore leaves a partially restored backup (for example keys and servers from the backup but old snippets/port forwards/settings), with no rollback or marker that the restore was incomplete. This violates whole-backup restore semantics and differs from Backup.merge, which explicitly wraps the whole restore in one transaction.
- lib/data/store/migrations/m004_kv_to_tables.dart: m004 is not restart-safe after its SQL transaction commits but before SchemaVersion advances: a retry can erase the already-rewritten order lists. For example, if the process dies after the transaction deletes
kv/serverbut before_store(5), the next run has an emptyserverIdsmap, yet_rewriteOrder('serverOrder', ...)still sees the old order and rewrites every entry to null, leavingserverOrderas[](and similarlysnippetOrder). Thus a crash in the documented retry window loses the user's ordering even though the entity rows survived. - lib/data/store/migrations/m003_hive_to_sqlite.dart: A box containing an unreadable individual record is marked complete even though its contents were only partially copied, so that record is never retried.
_importBoxcatches a per-record decode/JSON failure, continues, and still returnsopened: true;runIfNeededadds the box to_done, and a fully opened set then writes the global import marker. The retained Hive rollback file cannot help normal startup because the marker prevents any future read. - lib/data/store/migrations/m004_kv_to_tables.dart: Duplicate legacy private-key ids are not handled safely:
_migratePrivateKeysinserts each duplicate as a distinct row but assignsids[oldId] = idrepeatedly, so every server/reference using that old id is silently remapped to whichever duplicate happened to be processed last. If duplicate ids are instead duplicate names represented by different rows, the migration preserves both key blobs but loses the identity of all references to the earlier one. This is disproved only if the v4 format guarantees globally unique key ids for all historical data; the migration's own comment says uniqueness was not enforced. - lib/data/store/container.dart: A newer remote snapshot cannot delete per-server container settings:
BackupV2.mergedelegates eachcontainerentry toContainerStore.restoreOne, butrestoreOneonly upserts hosts/runtime and never removes rows absent from the incoming object. For example, device A deletes a server's Docker host (and its server timestamp advances), while device B still has the host; B merges A's newer backup, retains the host, andput/setTypealso stamps the server again, so the next upload can resurrect the supposedly deleted setting on A. This is introduced by the v5 table-backed container restore path; it would be disproved only if container deletion is explicitly intended to be non-synchronizable, contrary to the store comments and the parent-server timestamp design. - lib/data/model/app/bak/backup2.dart: BackupV2 restores container settings without applying the backup's timestamps or force/non-force deletion semantics.
restoreOnecallsContainerStore.put/setType, which stamps the owning server with the current local time, and it never removes host/runtime rows absent from the backup. Thus an older non-forced backup can overwrite a newer server's container host, and a forced restore can leave stale container settings that the backup deleted; the restore also makes the server look like a fresh local edit instead of preserving the incoming timestamp. This would be false only if container settings are intentionally excluded from restore conflict/deletion semantics and are guaranteed never to be changed by restore, which is contradicted byBackupV2.loadFromStoreincluding them andrestoreOnewriting them. - lib/data/store/migrations/m004_kv_to_tables.dart: A syntactically valid JSON object with a malformed field can brick the migration rather than be skipped or dropped. For example, a legacy server row with
"ssh":"corrupt"reachesv['ssh'] as Map?and throws a cast error (similarlytagsas a non-list,envsas a non-map, orjumpIdsas a non-list). The transaction rolls back, SchemaVersion remains v4, and the same row throws on every launch; unlike_rows's JSON-level catch, there is no per-record validation boundary. — The defect remains:_migrateServersstill evaluatesfinal ssh = v['ssh'] as Map?;directly inside the single migration transaction. For a valid JSON server object whosesshvalue is a string such as"corrupt", Dart throws a cast error before the row can be skipped, aborting the transaction and leaving the migration at v4. The same unguarded nullable casts remain fortags,envs, andjumpIds(as List?/as Map?). - lib/data/store/migrations/m004_kv_to_tables.dart: Duplicate legacy server identities abort the entire migration instead of being handled. If two kv/server rows have the same non-empty
v['id'](or a generated empty-id happens to collide), both are converted to that id and the secondINSERT INTO serverviolates the primary key. Because apply is retried at v4 after rollback, the same malformed/duplicate input fails on every launch; no records are migrated and the user cannot reach v5. The same unguarded behavior exists for duplicate port-forward ids at its INSERT. — The migration still derives each server id directly from the stored non-emptyv['id'](or generates one) and then executes a plainINSERT INTO serverwithout checking or remapping an already-used id. Thus two legacy rows sharing that id still cause a primary-key failure and abort the transaction. Port forwards likewise still use their legacy id in a plainINSERT INTO port_forwardwith no duplicate handling, so the stated duplicate port-forward failure remains as well. - lib/data/store/migrations/m004_kv_to_tables.dart: Unreadable or non-object source rows are silently made unrecoverable.
_rawcatches JSON decode errors and_rowsskips non-map values, but apply later unconditionally deletes every row in each consumed store. For example, one truncatedserverJSON value is logged and omitted, all other servers migrate, andDELETE FROM kv WHERE store = 'server'erases the truncated record; a later retry or manual recovery cannot recover it. The same applies to malformed rows in keys, snippets, port forwards, docker, conn_stat, and agent_conversation. — The defect remains:_rawstill catches JSON decode failures and_rowsstill skips non-map values, butapply()still unconditionally executesDELETE FROM kv WHERE store = ?for every store in_consumed. Thus unreadable or non-object rows are omitted from migration and then erased along with successfully migrated rows, preventing recovery or retry. - lib/data/store/migrations/m004_kv_to_tables.dart: The migration is not restart/idempotent across the commit/version-record boundary: after the transaction commits but before
SchemaVersion.migratestores v5, a crash leaves all consumed KV rows deleted whileserverOrder/snippetOrderremains inkv. On the next launchapplyrebuilds emptyserverIdsandsnippetNames, then_rewriteOrderresolves every existing entry to null and overwrites both order lists with[], losing the user's ordering (and any still-valid setting entries). The claim is false only if the version write is guaranteed atomic with the SQLite transaction, but it is a separate_store(v + 1)operation afterawait step.apply()and uses a different store path. — The defect remains.KvToTablesMigration.apply()still commits the SQLite transaction beforeSchemaVersion.migrate()calls_store(v + 1). If the process crashes in that gap, the consumed KV stores are gone whileserverOrderandsnippetOrderretain their rewritten values. On the retry,_migrateServers/_migrateSnippetssee no source rows and produce empty maps, and the current_rewriteOrderstill constructsrewrittenby dropping every entry whose resolver returns null, then updates the setting to[]. Thus the described loss of ordering can still occur. - lib/data/store/migrations/m003_hive_to_sqlite.dart: Malformed JSON-shaped records are not isolated per record in m004: unchecked casts such as
v['name'] as String?,v['ssh'] as Map?, and nested field casts occur after_rowsaccepts any Map, so one malformed server/key/snippet row throws inside the single transaction, rolls back all conversions, and causes the same failure on every launch rather than dropping or recording that bad row while migrating the rest. - lib/data/store/migrations/m003_hive_to_sqlite.dart: An install containing only the legacy plaintext
conn_stats_index.hiveis treated as a fresh install and the plaintext file is left behind.runIfNeededbuildspresentonly from_boxes(which intentionally excludesconn_stats_index); when that list is empty it returns throughSchemaVersion.initFresh()without calling_dropPlaintextIndex. The tests cover an entirely empty directory and an index alongside all normal boxes, but not the empty-legacy-box-list/index-only variant, so this data-protection cleanup regression is currently undetected. The claim would be false if another startup path independently deletes the index before this code runs, or if an index-only install is intentionally outside the supported legacy states. - lib/data/store/entity_store.dart: Deleting a server leaves live port-forward provider state inconsistent with the relational database.
- Deleting a private key changes the referencing server (
ssh_key_idbecomes NULL) without updating that server's sync metadata or clearing/replacing its cache. The schema's ON DELETE SET NULL fires inside the raw DELETE, but no ServerStore.touch/stamp is called; the key store only tombstones the key. Thus incremental sync can miss the server's credential change, and a cached ServerStore can continue returning a Spi with the deleted key ID until another server-store write invalidates it. This is false only if every private-key deletion caller separately stamps and invalidates ServerStore, but the schema test and the key store's own delete path provide no such trigger. — The currentPrivateKeyStorestill inheritsEntityStore.deleteByIdwithout overriding it. That implementation executes the private-key DELETE and only callssynced.tombstone(id), then invalidates the private-key store; it never finds the servers affected by theON DELETE SET NULL, callsServerStore.touch, or invalidatesServerStore. Consequently a referencing server'supdated_at/revremains unchanged for incremental sync, and an already-cachedServerStorecan retain the pre-deletessh_key_iduntil a separate server-store invalidation. - lib/data/store/tables.dart: Trusted SSH host fingerprints are migrated into the new
known_hosttable, but that table is absent fromTables.syncRootsandBackupV2has no field or merge path for it. After an upgrade,m004deletes the oldsetting/sshKnownHostFingerprintscopy, so the fingerprints are neither included in subsequent backups/sync nor restored on another device;trustHostonly stamps the server and cannot make the child rows travel. - lib/data/store/entity_store.dart: Entity-store sync can lose a newer edit when two edits occur in the same millisecond, despite the new schema's
revtie-breaker.SyncedTable.stampincrementsrev, butEntityStore.timestampsexports onlyupdated_at;EntityStore.mergecompares only those timestamps and skips when the incoming timestamp is<=the local timestamp. Thus a peer backup containing the later revision with the same millisecond timestamp is treated as stale and is never written. — The defect remains:SyncedTablestill maintainsrevin the schema, butEntityStore.timestampsexports onlyupdated_at, andmergestill gates a known record solely on(bakTs ?? 0) <= (current[id] ?? 0). Therefore two revisions with the same millisecond timestamp still compare equal and the incoming revision is skipped; neither the timestamp map nor the merge comparison carries or consultsrev. - lib/data/store/agent_conversation.dart: Saving a non-active conversation can delete the currently active conversation without selecting a replacement. With 30 conversations for a server and the active row pointing to the oldest one,
save(..., setActive: false)upserts a 31st row and_pruneServerdeletes the oldest row; the FK cascade removesagent_active_conversation, sofetchActivebecomes null even though 29 older/newer conversations remain. This changes active-selection behavior and violates the compound-write invariant for saves that do not explicitly change selection. It would be false only if callers guarantee that the active conversation is never the row pruned by a setActive:false save, but the store API and generic rename/save path do not enforce that. - A downgrade/future-schema install is not rejected before startup mutates its data.
_initDatacompletesStores.init()before_doDbMigrate()performs theSchemaTooNewExceptioncheck, and_doDbMigrateitself runsautoAddNewCards,autoAddNewFuncs, and writeslastVerbefore callingSchemaVersion.migrate. Thus a build supporting v5 opening a database marked v6 can rewrite settings (and, if the import marker is absent while legacy boxes remain,HiveImport.runIfNeededcan also copy legacy rows and reset the stored schema to v4) before eventually refusing or migrating it. A newer build can consequently lose future-build settings or have future data mixed with old imported data instead of getting a clean, recoverable downgrade failure. This is disproven only if all future-version databases are guaranteed to have the import marker and all pre-fixup settings already in exactly the shape that makes every pre-migration write a no-op; the ordering still permits those writes for a valid future database with stale/missing feature keys. — The downgrade check still occurs only after startup has opened and initialized the stores:_initDataawaitsStores.init()at the current call site, whileStores.init()runsHiveImport.runIfNeeded(),setting.removeRetiredKeys(),setting.migrateSshConnectionMode(), andsetting.migrateHomeTabsAgent()before returning. Then_doDbMigrate()still performsautoAddNewCards,autoAddNewFuncs, and writeslastVerbeforeSchemaVersion.migrate()can throw for a stored version greater thancurrent. Therefore a valid future-version database can still be mutated, and an unmarked database with legacy boxes can still be imported, before refusal. - Future-schema refusal occurs after startup has already initialized stores and run writes: Stores.init runs connectionStats.init and HiveImport.runIfNeeded, then removes retired keys and performs setting migrations before SchemaVersion.migrate checks
stored > current;_doDbMigratealso applies app fixups and writes lastVer before that check. A downgrade can therefore sweep/delete data or rewrite settings (and in an incomplete Hive-import state can import/version data) before refusing the newer schema, violating fail-closed downgrade protection. — The downgrade can still perform writes before the future-schema check.main.dartstill awaitsStores.init()before_doDbMigrate(), andStores.init()currently opens/creates SQLite, runsconnectionStats.init(),HiveImport.runIfNeeded(), removes retired keys, and performs setting migrations. In particular,HiveImport.runIfNeeded()can import Hive data, set schema markers, and delete the plaintext index beforeSchemaVersion.migrate()is called. Moreover,_doDbMigrate()still runsServerDetailCards.autoAddNewCards,ServerFuncBtn.autoAddNewFuncs, and updateslastVerbefore the subsequentSchemaVersion.migrate()future-version check. Thus a stored schema greater than current can still be refused only after the described data/settings writes or import activity. - lib/data/store/entity_store.dart: EntityStore.merge compares timestamps using the incoming serialized ID before applying reconcile(), so legacy name-keyed snippet backups can overwrite a newer local snippet. A pre-ID backup decodes to a fresh generated ID;
currentcontains the local generated ID,incoming[id]has no timestamp for the fresh ID, and the loop accepts the record.SnippetStore.reconcile()then maps it by name onto the existing local ID and write() replaces the newer row/children. The per-record timestamp must be resolved by stable name before the LWW comparison. This is false only if all supported backups always contain stable IDs, which contradicts the explicit legacy reconciliation path and compatibility obligation. — The defect remains inEntityStore.merge: it derivesbakTsandknownfrom the serialized key before callingreconcile(item). For a legacy name-keyed snippet,fromJsoncan produce a fresh ID, so the timestamp lookup still misses the local row; the laterreconcileremaps the item by name andwritecan replace that newer local snippet. The currentSnippetStore.reconcilecontinues to provide exactly this name-based legacy remapping path.
⚠️ Unverified risks (1)
- Container child state is not restored with last-write-wins semantics and deletions never propagate.
BackupV2.mergeunconditionally callsrestoreOneafter the server merge, whileContainerStore.getAllMapexports only host/runtime values (no per-row timestamp or tombstone) andrestoreOneonly inserts/updates present values. Thus, when a user removes a container host on device A (which stamps the parent server) and syncs to device B, B retains its old host because the absent key is never deleted; an older backup can also overwrite a newer local host.

📋 Additional findings from this change (not shown inline) (23)
- 🟠 High The editor stores the selected private key as a list index, but never remaps that index when the private-key provider reloads. If a key is inserted, deleted, or the provider reloads with a changed alphabetical order while this page is open, the displayed selection and the value saved can refer to a different key (or
_onSavecan callelementAtwith an out-of-range index and fail). (lib/view/page/server/edit/actions.dart) — anchor-outside-diff - 🟠 High Deleting a server removes it from
ServersStateand the durable store but does not invalidate or dispose itsserverProvider(id)notifier, nor clearserverSelectionProvider. Existing detail/dependent views keyed by that id therefore retain the oldServerState/client after deletion; actions such as custom commands, SFTP, process, or power controls can still read the stale notifier and attempt operations for a server that no longer exists. (lib/data/provider/server/all.dart) — anchor-unreliable - 🟠 High A legacy install containing only
conn_stats_index.hiveis treated as a fresh install and the plaintext index is never removed._boxesintentionally excludes the index, sopresentis empty, the fresh-install branch sets the import marker and returns before_dropPlaintextIndex; the next launch also returns on the marker. This leaves connection identifiers/timestamps in plaintext indefinitely, contrary to the import's stated invariant that the index is deleted. The claim would be false only if some other startup path independently deletesconn_stats_index.hive(none is visible in the inspected initialization path) or if such an index-only install is explicitly unsupported. Add the index to presence/cleanup handling and a regression fixture/test for an index-only legacy directory. (lib/data/store/migrations/m003_hive_to_sqlite.dart) — anchor-outside-diff - 🟠 High Legacy servers with both SSH and monitor credentials are silently dropped by the migration, violating lossless compatibility.
_migrateServerstreatshasSsh == hasMonitoras unrepresentable and skips the row; the prior model could store both andSpi.toJsoncan carry both. Upgrading such an installation removes the server and all of its nested data rather than preserving it or reporting a recoverable conflict. — anchor-unreliable - 🟠 High The password-fallback path can overwrite an encrypted remote after a read failure without setting the newer-schema guard.
BakSyncer.fromFilecatches every exception from the encrypted parse (including decryption/authentication failure) and then callsMergeableUtils.fromJsonString(content)without a password; that call still fails for encrypted content, but_remoteTooNewremains null. The base sync cycle then catches the read/merge failure and its unconditional upload path can replace the remote encrypted/newer payload with this device's local copy. Thus a wrong/missing password or an encrypted payload that cannot be decrypted is not fail-closed, contrary to the downgrade protection. (lib/core/sync.dart) — anchor-unreliable - 🟠 High A remote backup that cannot be decrypted is still eligible for overwrite.
fromFileonly records_remoteTooNewfor a successful decrypt followed by a version check; a wrong/changed password (or an encrypted payload that the current parser cannot decode) goes through the generic fallback and leaves the guard null. The baseSyncIfacethen catches the parse/merge error and performs its unconditional upload, replacing the unreadable encrypted remote with this device's copy. This is reproducible when device A changes the backup password or has a different password from the remote and an automatic sync runs; it would be false only ifSyncIfaceindependently refuses uploads after everyfromFilefailure, contrary to the documented unconditional-upload behavior in this change. (lib/core/sync.dart) — anchor-unreliable - 🟡 Medium m004 preserves per-server agent conversations and active rows whose server reference cannot be resolved, creating orphaned data that no server can reach. (lib/data/store/migrations/m004_kv_to_tables.dart) — per-file-budget
- 🟡 Medium Legacy-file inheritance is not part of the sync lifecycle and can race the first versioned upload.
_doDbMigratelaunchesinheritLegacyRemote()withunawaited; meanwhile startup/home/provider code can callbakSync.sync. If the versioned file is absent, the sync can upload the current local (pre-inheritance) state tosrvbox_bak_v3.jsonbefore the legacy download/merge completes.inheritLegacyRemoteonly merges locally and never uploads the merged result, so the new remote history permanently omits the legacy servers/snippets/keys until a later user mutation happens to trigger another sync. The same race can also allow the legacy merge to modify stores whileBackupV2.loadFromStoreis assembling an upload. This would be false only ifSyncIfaceserializes arbitrary calls against this separately-invoked method, which this class does not arrange. (lib/main.dart) — inline-budget - 🟡 Medium The schema's reachability CHECK accepts empty connection strings, contrary to the migration and model invariant that a server must have a usable SSH host or monitor address.
CHECK ((ssh_ip IS NOT NULL) <> (monitor_addr IS NOT NULL))treatsssh_ip = ''(and likewisemonitor_addr = '') as configured, so a direct SQL/entity write can persist a server that has neither usable endpoint; the added schema tests cover only NULL versus non-NULL and would pass this invalid row. (lib/data/store/db.dart) — inline-budget - 🟡 Medium Saving a server with a duplicate name is not converted into the localized duplicate-name error: the editor awaits addServer/updateServer without catching DuplicateNameException, so the form does not remain in a clear editable state and the user can receive an uncaught/raw error instead of the required localized message. (lib/view/page/server/edit/actions.dart) — inline-budget
- 🟡 Medium A server whose stored
ssh_key_idno longer exists is initialized with_keyIdx == -1, and that sentinel is treated as an active-but-empty key-auth selection. Even when the server still has a valid password, saving the editor always rejects it with theemptytoast instead of preserving password authentication or clearing the stale key reference. The same stale-1also makes the key-auth switch appear enabled. (lib/view/page/server/edit/actions.dart) — inline-budget - 🟡 Medium Malformed nested server data can abort the whole atomic m004 transaction instead of dropping only the malformed record. For example, a server with
custom: 'not-a-map'reachesfinal custom = v['custom'] as Map?and throws a type-cast error; similar unchecked casts exist for nested fields and child collections. Since_rowsonly catches JSON decoding and there is no per-row boundary around_migrateServers, the transaction rolls back all otherwise valid records and schema advancement cannot complete. (lib/data/store/migrations/m004_kv_to_tables.dart) — inline-budget - 🟡 Medium The server editor still stores the selected private key as a positional list index, so a key rename/reorder or provider reload while the form is open can save a different key than the one displayed (or produce an invalid selection). (lib/view/page/server/edit/edit.dart) — inline-budget
- 🟡 Medium Connection-stat ordering and pruning are nondeterministic for attempts in the same millisecond. History, the per-server window function, and the 100-row pruning subquery all order only by
timestamp; two generated-ID rows with equal timestamps may swap order, changing which server name is selected as current, the recent list order, and which tied 101st record is deleted. (lib/data/store/connection_stats.dart) — anchor-unreliable - 🟡 Medium The relational schema does not constrain port numbers even though the table is now the authoritative storage and backup/restore writes can bypass UI validation.
PortForwardsonly adds a CHECK ontype;local_portdefaults to 0 with no range check andremote_portis nullable with no range check. Consequently a directPortForwardStore.putor a crafted backup can persist -1, 70000, or an invalid remote port, and the provider later attempts to use that invalid endpoint. This would be false only if every writer were independently guaranteed to validate both ports, whichPortForwardConfigdoes not do and the store'swritedoes not do. (lib/data/store/tables.dart) — anchor-unreliable - 🟡 Medium Deleting a private key updates
server.ssh_key_idin SQLite viaON DELETE SET NULL, but does not invalidate or notifyServerStore, leaving cachedSpiobjects with the deleted key id.PrivateKeyNotifier.deletecallsStores.key.deleteonly;PrivateKeyStorehas no dependent-server invalidation, whileServerStore.fetch()returns its cache until one of its own writes callsinvalidate(). Thus an already-loaded server list can continue resolving the removed key id and attempt to use a key that no longer exists (and the UI will not reflect the reference being cleared) until an unrelated server write/reload. This is false only if every key deletion is followed by a guaranteed global server reload before any server read; the shown deletion path does not do that. — anchor-unreliable - 🟡 Medium A v2 remote merge is not atomic across stores, so a failed/interrupted sync can leave a partial restore that is then eligible for upload.
BackupV2.mergecommits keys, servers, snippets, port forwards, containers, and only later history/settings through separate store calls; unlike the legacyBackup.merge, there is no enclosing transaction. For example, a process interruption or SQLite error afterStores.key.merge/Stores.server.mergebut before the remaining sections leaves references and records from different sides, and the next sync serializes that partial local state. This is false only if everyStores.*.mergeimplementation participates in one shared transaction despite the absence of a transaction around these calls. (lib/data/model/app/bak/backup2.dart) — anchor-unreliable - 🟡 Medium The split snippet pane identifies the open record by its mutable name, so renaming a snippet through the new ID-based notifier drops the pane selection and editor on the next provider rebuild instead of continuing to edit the same record. (lib/view/page/snippet/list.dart) — anchor-unreliable
- 🟡 Medium Private-key persistence failures other than duplicate names are shown directly with e.toString(), allowing raw SQLite/storage diagnostics to reach the user and then rethrowing from the save callback; this violates the user-facing migration/storage error contract. (lib/view/page/private_key/edit.dart) — anchor-unreliable
- 🟡 Medium Private-key save still exposes raw SQLite exception text in the editor instead of a user-facing/localized error for database failures. (lib/view/page/private_key/edit.dart) — anchor-unreliable
- 🟡 Medium The migration API documentation is now false for the new storage chain:
SchemaMigration.applystill says every migration rewrites Hive stores in place, whileKvToTablesMigrationoperates on SQLitekvand is the only registered migration afterHiveImport. This misdirects future migration authors toward the wrong engine and conflicts with the architecture guidance that Hive is read-only compatibility input. (lib/data/store/schema.dart) — anchor-unreliable - 🔵 Low The
SchemaMigration.applyAPI documentation says migrations “rewrite the local Hive stores in place,” but the only registered migration (KvToTablesMigration) runs after Hive import and rewrites SQLitekvinto SQLite entity tables. This is materially misleading for anyone implementing the next step: following the contract would target the retired source engine, and it also contradicts the architecture documentation's SQLite migration chain. The claim would be false only if another caller passed a Hive-backed migration list, which the inspected startup and tests do not do; update the interface comment to describe the current storage engine (or explicitly say the engine is migration-specific). — anchor-unreliable - 🔵 Low The fixture README's box counts are inconsistent with the artifacts and the release test: it labels v1.0.1466/1480 as having 8 boxes and v1.0.1491 as 9, while each directory contains those encrypted boxes plus
conn_stats_index.hive(9 files for 1466/1480 and 10 for 1491), and the test explicitly treats the plaintext index as a box/file. A maintainer using the README to verify a regenerated fixture can therefore accept a missing legacy box or misread the expected count. This would be false only if “Boxes” is explicitly defined as “encrypted data boxes excluding the index”; the README currently calls the index a box in its contents and does not define that exclusion. Clarify the count (encrypted boxes vs total files) and update the table. (test/fixtures/README.md) — anchor-unreliable
♻️ Previously reported (still present) (10)
- 🟠 High A destination write failure is treated as a successfully opened/imported box.
_importBoxlogsinto(...) == falsebut still returnsopened: true; the caller adds that box todone, and when all boxes are otherwise readable it writes the import marker. A transient SQLite/storage failure therefore permanently marks the box complete even though rows are missing, with no retry on later launches. (lib/data/store/migrations/m003_hive_to_sqlite.dart) — previously-reported - 🟠 High Duplicate legacy private-key identities overwrite the remapping entry, so servers can be attached to the wrong key.
_migratePrivateKeysdeliberately permits duplicate records by generating unique names, but stores onlyids[oldId] = id; if two imported rows have the samevalue.id(or both fall back to the same key identity), the later key wins and every server referencing that old identity is rewritten to the later key rather than preserving the original association. The same ambiguity exists for server IDs: a duplicate non-emptyserver.idcauses the second INSERT to violate the primary key and rolls back the migration. This would be false only if the legacy KV format guarantees identity uniqueness independently of its store key, a guarantee the migration comments explicitly say was not enforced for private keys. (lib/data/store/migrations/m004_kv_to_tables.dart) — previously-reported - 🟠 High A malformed/duplicated server record can roll back every migration rather than being dropped.
_migrateServersinserts any non-empty legacyv['id']directly as the new primary key; if two KV rows have the same id (for example a corrupt row whose KV key differs from its duplicated embedded id), the secondINSERT INTO serverraises a UNIQUE constraint. Becauseapplywraps all stores in one transaction and does not catch per-record SQL errors, valid keys and servers already inserted are rolled back and the schema remains v4. This would be false only if the pre-m004 data contract guarantees embedded server IDs are unique, despite the migration explicitly handling malformed/old records and not validating that invariant. (lib/data/store/migrations/m004_kv_to_tables.dart) — previously-reported - 🟠 High Incremental merge ignores the new per-row
rev, so two edits made in the same millisecond do not have last-write-wins semantics.EntityStore.mergeskips an incoming record wheneverbakTs <= current[id]; becausetimestampscarries onlyupdated_atand notrev, equal timestamps are treated as already handled even when the incoming row has a later revision. A peer that edits twice within one millisecond can therefore lose the later edit based solely on merge arrival order. (lib/data/store/entity_store.dart) — previously-reported - 🟠 High Restoring a backup can detach or skip servers when a private key is reconciled by name to a different local id.
PrivateKeyStore.reconcilechanges an incoming key's id to the existing same-name key, butServerStorelater writes the incomingSpiunchanged, whosesshKeyIdstill points to the backup key id. The server table has a foreign key toprivate_key(id); with foreign keys enabled this update/insert fails (andEntityStore.mergeskips that record), so a valid server from the backup is omitted instead of being rewritten to the reconciled key id. (lib/data/store/private_key.dart) — previously-reported - 🟠 High Private-key reconciliation does not rewrite incoming server references, so a restore can silently drop every server that uses a same-name key with a different ID. If the local database has key
(id=K2,name=foo)and the backup has(id=K1,name=foo)plus a server whosessh_key_idis K1,PrivateKeyStore.reconcilemaps the key to K2, butBackupV2.mergepasses the server JSON unchanged;ServerStore.writethen violates theserver.ssh_key_id → private_key.idFK and EntityStore.merge catches/skips that server. (lib/data/store/private_key.dart) — previously-reported - 🟠 High An unreadable known-host JSON value is deleted even though
_migrateKnownHostsdeliberately returns without recovering it. On malformed JSON, the function logs and returns, butapplyunconditionally executes DELETE forsshKnownHostFingerprints; the migration then advances to v5, irreversibly dropping all known-host fingerprints instead of following a skip/retry policy. (lib/data/store/migrations/m004_kv_to_tables.dart) — previously-reported - 🟠 High Container settings are not represented as syncable child records and are not carried through backup merge with per-setting last-write-wins or deletion semantics.
ContainerStorestores host/runtime rows without updated_at/rev, while its restore methods only add supplied nonempty hosts and set a runtime; restoring a newer state that removed a host/runtime leaves the old row in place. Thus a restore/sync can retain deleted container configuration and cannot resolve concurrent container edits by revision. (lib/data/store/container.dart) — previously-reported - 🟡 Medium Port-forward rows accept invalid port values: the relational table constrains only
type, whilelocal_porthas default 0 and neither local nor remote port has a range check. A direct SQL insert, backup merge, orPortForwardStore.putcan therefore persist negative or >65535 ports, and the model/provider can later return them as valid configurations. (lib/data/store/db.dart) — previously-reported - 🟡 Medium A server cache can retain a deleted private-key reference.
PrivateKeyNotifier.deletedeletes the key row but only updates the key provider state; it does not drop/invalidateServerStore's cachedSpilist or reload the server provider. Any code reading the already-cached server continues to expose the oldssh.keyIduntil an unrelated server write/reload, so key deletion leaves model/cache state inconsistent with the foreign-key SET NULL result in SQLite. (lib/data/provider/private_key.dart) — previously-reported
❓ Low-evidence leads (not confirmed — verify before acting) (3)
- The v4→v5 server migration changes jump-chain meaning when legacy
jumpIdand the newerjumpIdsare both present.SshCredential.resolvedJumpIdsexplicitly usesjumpIdsfirst and falls back tojumpIdonly when that list yields nothing, but_migrateServersalways constructsorderedas[ssh['jumpId'], ...ssh['jumpIds']]. A record withjumpId = oldandjumpIds = ['preferred']is therefore migrated witholdas ordinal 0 andpreferredas ordinal 1, whereas the release model would use onlypreferred(and the connection code consumes the first candidates). This can route connections through the wrong jump host after upgrade. The claim is false only if old stored records are guaranteed never to contain both fields with differing values; the model and migration explicitly support both legacy and new fields and do not enforce that guarantee. (lib/data/store/migrations/m004_kv_to_tables.dart) - Duplicate non-empty server IDs in legacy rows cause the entire m004 migration to roll back rather than handling the malformed duplicate according to the stated skip/drop policy.
_migrateServersuses the embedded ID directly and executes a plain INSERT into the server table, whoseidis the primary key; the second row raises a constraint exception before the consumed KV stores are deleted or the schema version advances.

## Unresolved from the previous review — these block approval, fix them first (27)
In lib/core/sync.dart, address this finding:
The upload guard does not cover merge failures, so a remote payload that parses successfully but fails while being applied is still replaced by the local snapshot. `backup` only refuses when `_remoteTooNew` is set by `fromFile`; `merge()` never sets that flag, and the base lifecycle is explicitly described here as uploading after a caught merge failure. For example, a parsed backup can reach store application and throw from a transaction/SQLite write (or a legacy whole-store restore), after which the sync cycle uploads without having established that the remote state was safely incorporated. The remote data is preserved only when the failure happens to be classified as `SchemaTooNewException`; any other merge exception leaves the overwrite path open.
In lib/data/store/migrations/m004_kv_to_tables.dart, address this finding:
m004 is not tolerant of duplicate/invalid legacy server records: two `kv/server` rows can carry the same non-empty internal `id` (or a generated ID can collide), and `_migrateServers` executes a plain `INSERT INTO server` for each without deduplication or per-record recovery. SQLite raises the primary-key constraint inside the outer transaction, aborting the entire migration and leaving schema version at v4, so the app cannot complete startup on that installation. The migration's stated invalid-record policy only drops SSH/monitor-invalid rows and does not cover duplicate IDs.
In lib/data/provider/port_forward_provider.dart, address this finding:
A local or remote forwarding connection can be added after provider disposal/disconnect has already finished closing the entry, so its socket/channel is never included in the close snapshot and leaks.
In lib/data/provider/port_forward_provider.dart, address this finding:
The migration tests never exercise a legacy data box that exists only as `<name>.hive` (the pre-encryption variant). `HiveImport.runIfNeeded` explicitly promises to detect and import either `<name>_enc.hive` or `<name>.hive`, but `seedHive()` creates boxes through `HiveStore` (encrypted), and the release test copies only `_enc` fixtures; its added plain `snippet.hive` is an empty directory used to force an open failure while `snippet_enc.hive` remains the actual data source, not a plain-data import. Consequently a regression in the plain-file discovery/open path can pass all permanent tests. This is disproved only if another permanent migration test seeds real records in a plain legacy box and runs the full import.
In lib/data/store/private_key.dart, address this finding:
Newer-schema refusal happens after several writes, so a downgraded build is not read-only while it is supposed to preserve the newer data. `Stores.init` runs setting fixups (`removeRetiredKeys`, SSH mode/home-tab migrations) and can run Hive import before `_doDbMigrate`; `_doDbMigrate` itself updates feature settings before calling `SchemaVersion.migrate`. With a stored schema version above the supported version, those writes occur and only then does `SchemaTooNewException` stop the launch. The claim would be false only if all these preflight writes were proven absent for a newer-schema database, but they are unconditional/flag-driven initialization paths.
Somewhere in the code under review, address this finding:
A failed read of an encrypted remote backup can still cause the base sync cycle to overwrite that remote with this device's local backup. `fromFile` only records `_remoteTooNew` for `SchemaTooNewException`; when `Cryptor.decrypt` fails (wrong/missing password, damaged encrypted payload, or a password rotation), the broad catch retries the no-password reader, which also fails, and rethrows a non-schema exception. The inherited `SyncIface` cycle is documented here as catching merge/read failures and then uploading unconditionally, while `backup` only vetoes the schema-too-new flag. Thus an encrypted remote that this device cannot decrypt is treated as an ordinary parse failure and is replaced by the local copy. This is disproven only if the actual `SyncIface._sync` implementation aborts without calling `backup` for non-schema `fromFile` failures (contrary to the lifecycle contract relied on by this change).
Somewhere in the code under review, address this finding:
Encrypted remote parse/decryption failures are not marked as unsafe remote data, so after fromFile fails the base sync flow can still execute its unconditional upload and overwrite the unreadable encrypted payload with this device's copy.
In lib/data/model/app/bak/backup2.dart, address this finding:
BackupV2.merge is not atomic. It commits key, server, snippet, port-forward, and container changes before the separately awaited history/settings merges, and each entity merge has its own transaction. A process kill, database error, or failure while restoring a later store therefore leaves a partially restored backup (for example keys and servers from the backup but old snippets/port forwards/settings), with no rollback or marker that the restore was incomplete. This violates whole-backup restore semantics and differs from Backup.merge, which explicitly wraps the whole restore in one transaction.
In lib/data/store/migrations/m004_kv_to_tables.dart, address this finding:
m004 is not restart-safe after its SQL transaction commits but before SchemaVersion advances: a retry can erase the already-rewritten order lists. For example, if the process dies after the transaction deletes `kv/server` but before `_store(5)`, the next run has an empty `serverIds` map, yet `_rewriteOrder('serverOrder', ...)` still sees the old order and rewrites every entry to null, leaving `serverOrder` as `[]` (and similarly `snippetOrder`). Thus a crash in the documented retry window loses the user's ordering even though the entity rows survived.
In lib/data/store/migrations/m003_hive_to_sqlite.dart, address this finding:
A box containing an unreadable individual record is marked complete even though its contents were only partially copied, so that record is never retried. `_importBox` catches a per-record decode/JSON failure, continues, and still returns `opened: true`; `runIfNeeded` adds the box to `_done`, and a fully opened set then writes the global import marker. The retained Hive rollback file cannot help normal startup because the marker prevents any future read.
In lib/data/store/migrations/m004_kv_to_tables.dart, address this finding:
Duplicate legacy private-key ids are not handled safely: `_migratePrivateKeys` inserts each duplicate as a distinct row but assigns `ids[oldId] = id` repeatedly, so every server/reference using that old id is silently remapped to whichever duplicate happened to be processed last. If duplicate ids are instead duplicate names represented by different rows, the migration preserves both key blobs but loses the identity of all references to the earlier one. This is disproved only if the v4 format guarantees globally unique key ids for all historical data; the migration's own comment says uniqueness was not enforced.
In lib/data/store/container.dart, address this finding:
A newer remote snapshot cannot delete per-server container settings: `BackupV2.merge` delegates each `container` entry to `ContainerStore.restoreOne`, but `restoreOne` only upserts hosts/runtime and never removes rows absent from the incoming object. For example, device A deletes a server's Docker host (and its server timestamp advances), while device B still has the host; B merges A's newer backup, retains the host, and `put`/`setType` also stamps the server again, so the next upload can resurrect the supposedly deleted setting on A. This is introduced by the v5 table-backed container restore path; it would be disproved only if container deletion is explicitly intended to be non-synchronizable, contrary to the store comments and the parent-server timestamp design.
In lib/data/model/app/bak/backup2.dart, address this finding:
BackupV2 restores container settings without applying the backup's timestamps or force/non-force deletion semantics. `restoreOne` calls `ContainerStore.put`/`setType`, which stamps the owning server with the current local time, and it never removes host/runtime rows absent from the backup. Thus an older non-forced backup can overwrite a newer server's container host, and a forced restore can leave stale container settings that the backup deleted; the restore also makes the server look like a fresh local edit instead of preserving the incoming timestamp. This would be false only if container settings are intentionally excluded from restore conflict/deletion semantics and are guaranteed never to be changed by restore, which is contradicted by `BackupV2.loadFromStore` including them and `restoreOne` writing them.
In lib/data/store/migrations/m004_kv_to_tables.dart, address this finding:
A syntactically valid JSON object with a malformed field can brick the migration rather than be skipped or dropped. For example, a legacy server row with `"ssh":"corrupt"` reaches `v['ssh'] as Map?` and throws a cast error (similarly `tags` as a non-list, `envs` as a non-map, or `jumpIds` as a non-list). The transaction rolls back, SchemaVersion remains v4, and the same row throws on every launch; unlike `_rows`'s JSON-level catch, there is no per-record validation boundary.
In lib/data/store/migrations/m004_kv_to_tables.dart, address this finding:
Duplicate legacy server identities abort the entire migration instead of being handled. If two kv/server rows have the same non-empty `v['id']` (or a generated empty-id happens to collide), both are converted to that id and the second `INSERT INTO server` violates the primary key. Because apply is retried at v4 after rollback, the same malformed/duplicate input fails on every launch; no records are migrated and the user cannot reach v5. The same unguarded behavior exists for duplicate port-forward ids at its INSERT.
In lib/data/store/migrations/m004_kv_to_tables.dart, address this finding:
Unreadable or non-object source rows are silently made unrecoverable. `_raw` catches JSON decode errors and `_rows` skips non-map values, but apply later unconditionally deletes every row in each consumed store. For example, one truncated `server` JSON value is logged and omitted, all other servers migrate, and `DELETE FROM kv WHERE store = 'server'` erases the truncated record; a later retry or manual recovery cannot recover it. The same applies to malformed rows in keys, snippets, port forwards, docker, conn_stat, and agent_conversation.
In lib/data/store/migrations/m004_kv_to_tables.dart, address this finding:
The migration is not restart/idempotent across the commit/version-record boundary: after the transaction commits but before `SchemaVersion.migrate` stores v5, a crash leaves all consumed KV rows deleted while `serverOrder`/`snippetOrder` remains in `kv`. On the next launch `apply` rebuilds empty `serverIds` and `snippetNames`, then `_rewriteOrder` resolves every existing entry to null and overwrites both order lists with `[]`, losing the user's ordering (and any still-valid setting entries). The claim is false only if the version write is guaranteed atomic with the SQLite transaction, but it is a separate `_store(v + 1)` operation after `await step.apply()` and uses a different store path.
In lib/data/store/migrations/m003_hive_to_sqlite.dart, address this finding:
Malformed JSON-shaped records are not isolated per record in m004: unchecked casts such as `v['name'] as String?`, `v['ssh'] as Map?`, and nested field casts occur after `_rows` accepts any Map, so one malformed server/key/snippet row throws inside the single transaction, rolls back all conversions, and causes the same failure on every launch rather than dropping or recording that bad row while migrating the rest.
In lib/data/store/migrations/m003_hive_to_sqlite.dart, address this finding:
An install containing only the legacy plaintext `conn_stats_index.hive` is treated as a fresh install and the plaintext file is left behind. `runIfNeeded` builds `present` only from `_boxes` (which intentionally excludes `conn_stats_index`); when that list is empty it returns through `SchemaVersion.initFresh()` without calling `_dropPlaintextIndex`. The tests cover an entirely empty directory and an index alongside all normal boxes, but not the empty-legacy-box-list/index-only variant, so this data-protection cleanup regression is currently undetected. The claim would be false if another startup path independently deletes the index before this code runs, or if an index-only install is intentionally outside the supported legacy states.
In lib/data/store/entity_store.dart, address this finding:
Deleting a server leaves live port-forward provider state inconsistent with the relational database.
Somewhere in the code under review, address this finding:
Deleting a private key changes the referencing server (`ssh_key_id` becomes NULL) without updating that server's sync metadata or clearing/replacing its cache. The schema's ON DELETE SET NULL fires inside the raw DELETE, but no ServerStore.touch/stamp is called; the key store only tombstones the key. Thus incremental sync can miss the server's credential change, and a cached ServerStore can continue returning a Spi with the deleted key ID until another server-store write invalidates it. This is false only if every private-key deletion caller separately stamps and invalidates ServerStore, but the schema test and the key store's own delete path provide no such trigger.
In lib/data/store/tables.dart, address this finding:
Trusted SSH host fingerprints are migrated into the new `known_host` table, but that table is absent from `Tables.syncRoots` and `BackupV2` has no field or merge path for it. After an upgrade, `m004` deletes the old `setting/sshKnownHostFingerprints` copy, so the fingerprints are neither included in subsequent backups/sync nor restored on another device; `trustHost` only stamps the server and cannot make the child rows travel.
In lib/data/store/entity_store.dart, address this finding:
Entity-store sync can lose a newer edit when two edits occur in the same millisecond, despite the new schema's `rev` tie-breaker. `SyncedTable.stamp` increments `rev`, but `EntityStore.timestamps` exports only `updated_at`; `EntityStore.merge` compares only those timestamps and skips when the incoming timestamp is `<=` the local timestamp. Thus a peer backup containing the later revision with the same millisecond timestamp is treated as stale and is never written.
In lib/data/store/agent_conversation.dart, address this finding:
Saving a non-active conversation can delete the currently active conversation without selecting a replacement. With 30 conversations for a server and the active row pointing to the oldest one, `save(..., setActive: false)` upserts a 31st row and `_pruneServer` deletes the oldest row; the FK cascade removes `agent_active_conversation`, so `fetchActive` becomes null even though 29 older/newer conversations remain. This changes active-selection behavior and violates the compound-write invariant for saves that do not explicitly change selection. It would be false only if callers guarantee that the active conversation is never the row pruned by a setActive:false save, but the store API and generic rename/save path do not enforce that.
Somewhere in the code under review, address this finding:
A downgrade/future-schema install is not rejected before startup mutates its data. `_initData` completes `Stores.init()` before `_doDbMigrate()` performs the `SchemaTooNewException` check, and `_doDbMigrate` itself runs `autoAddNewCards`, `autoAddNewFuncs`, and writes `lastVer` before calling `SchemaVersion.migrate`. Thus a build supporting v5 opening a database marked v6 can rewrite settings (and, if the import marker is absent while legacy boxes remain, `HiveImport.runIfNeeded` can also copy legacy rows and reset the stored schema to v4) before eventually refusing or migrating it. A newer build can consequently lose future-build settings or have future data mixed with old imported data instead of getting a clean, recoverable downgrade failure. This is disproven only if all future-version databases are guaranteed to have the import marker and all pre-fixup settings already in exactly the shape that makes every pre-migration write a no-op; the ordering still permits those writes for a valid future database with stale/missing feature keys.
Somewhere in the code under review, address this finding:
Future-schema refusal occurs after startup has already initialized stores and run writes: Stores.init runs connectionStats.init and HiveImport.runIfNeeded, then removes retired keys and performs setting migrations before SchemaVersion.migrate checks `stored > current`; `_doDbMigrate` also applies app fixups and writes lastVer before that check. A downgrade can therefore sweep/delete data or rewrite settings (and in an incomplete Hive-import state can import/version data) before refusing the newer schema, violating fail-closed downgrade protection.
In lib/data/store/entity_store.dart, address this finding:
EntityStore.merge compares timestamps using the incoming serialized ID before applying reconcile(), so legacy name-keyed snippet backups can overwrite a newer local snippet. A pre-ID backup decodes to a fresh generated ID; `current` contains the local generated ID, `incoming[id]` has no timestamp for the fresh ID, and the loop accepts the record. `SnippetStore.reconcile()` then maps it by name onto the existing local ID and write() replaces the newer row/children. The per-record timestamp must be resolved by stable name before the LWW comparison. This is false only if all supported backups always contain stable IDs, which contradicts the explicit legacy reconciliation path and compatibility obligation.
## Findings on this change (also posted as inline comments) (4)
In lib/data/store/migrations/m004_kv_to_tables.dart around line 187, address this finding:
Legacy servers with both SSH and monitor credentials are silently dropped by the migration, violating lossless compatibility. `_migrateServers` treats `hasSsh == hasMonitor` as unrepresentable and skips the row; the prior model could store both and `Spi.toJson` can carry both. Upgrading such an installation removes the server and all of its nested data rather than preserving it or reporting a recoverable conflict.
In lib/data/model/app/bak/backup2.dart around line 81, address this finding:
Container settings are not merged losslessly: restoring a newer server state cannot remove a host/runtime child that is absent from the backup, and an older container payload is applied even when the corresponding server record is rejected by LWW. For example, device A deletes a server's Docker host (or changes its runtime), then merges a backup containing the older server/container data; `BackupV2.merge` applies `restoreOne` to every container entry unconditionally, while `restoreOne` only inserts values that are present and never deletes missing `host_*` or `runtime` rows. The deleted/changed child therefore remains locally and can continue to affect connections after the server merge. This is introduced by the new child-table backup path; it would be false only if container entries were guaranteed to be complete, timestamped, and filtered against the server merge before this method is called.
In lib/data/model/app/bak/backup2.dart around line 77, address this finding:
A BackupV2 merge is not atomic across the relational roots and dependent sections. The entity stores commit each `merge` independently, then container writes commit independently, while history/settings are launched in a separate `Future.wait`; if a later section fails (for example a malformed or constraint-invalid history/settings entry, or an interrupted process), keys/servers/snippets/port forwards and possibly container state have already been committed. This violates the restore invariant that a failed merge must not leave partial relational state; only the legacy `Backup.merge` uses one transaction for the whole restore.
In lib/data/model/app/bak/backup2.dart around line 100, address this finding:
A backup merge that changes only container settings does not notify/reload the server provider, so the UI can keep showing stale server data until an unrelated server reload. `restoreOne` mutates the child tables and calls `Stores.server.invalidate()`, but `BackupV2.merge` only explicitly reloads `serversProvider` when `serversChanged` is true; it does not use the server store change stream to reload the provider. Since container settings are deliberately represented as children of a server, this is a stale notification/cache path for exactly the settings that were moved into the relational schema. It would be false only if every consumer of server/container data independently listens to the store stream and rebuilds, but the merge code's explicit provider reload is the apparent notification boundary.
## Additional findings on this change (not posted inline) (23)
In lib/view/page/server/edit/actions.dart around line 311, address this finding:
The editor stores the selected private key as a list index, but never remaps that index when the private-key provider reloads. If a key is inserted, deleted, or the provider reloads with a changed alphabetical order while this page is open, the displayed selection and the value saved can refer to a different key (or `_onSave` can call `elementAt` with an out-of-range index and fail).
In lib/data/provider/server/all.dart, address this finding:
Deleting a server removes it from `ServersState` and the durable store but does not invalidate or dispose its `serverProvider(id)` notifier, nor clear `serverSelectionProvider`. Existing detail/dependent views keyed by that id therefore retain the old `ServerState`/client after deletion; actions such as custom commands, SFTP, process, or power controls can still read the stale notifier and attempt operations for a server that no longer exists.
In lib/data/store/migrations/m003_hive_to_sqlite.dart around line 116, address this finding:
A legacy install containing only `conn_stats_index.hive` is treated as a fresh install and the plaintext index is never removed. `_boxes` intentionally excludes the index, so `present` is empty, the fresh-install branch sets the import marker and returns before `_dropPlaintextIndex`; the next launch also returns on the marker. This leaves connection identifiers/timestamps in plaintext indefinitely, contrary to the import's stated invariant that the index is deleted. The claim would be false only if some other startup path independently deletes `conn_stats_index.hive` (none is visible in the inspected initialization path) or if such an index-only install is explicitly unsupported. Add the index to presence/cleanup handling and a regression fixture/test for an index-only legacy directory.
Somewhere in the code under review, address this finding:
Legacy servers with both SSH and monitor credentials are silently dropped by the migration, violating lossless compatibility. `_migrateServers` treats `hasSsh == hasMonitor` as unrepresentable and skips the row; the prior model could store both and `Spi.toJson` can carry both. Upgrading such an installation removes the server and all of its nested data rather than preserving it or reporting a recoverable conflict.
In lib/core/sync.dart, address this finding:
The password-fallback path can overwrite an encrypted remote after a read failure without setting the newer-schema guard. `BakSyncer.fromFile` catches every exception from the encrypted parse (including decryption/authentication failure) and then calls `MergeableUtils.fromJsonString(content)` without a password; that call still fails for encrypted content, but `_remoteTooNew` remains null. The base sync cycle then catches the read/merge failure and its unconditional upload path can replace the remote encrypted/newer payload with this device's local copy. Thus a wrong/missing password or an encrypted payload that cannot be decrypted is not fail-closed, contrary to the downgrade protection.
In lib/core/sync.dart, address this finding:
A remote backup that cannot be decrypted is still eligible for overwrite. `fromFile` only records `_remoteTooNew` for a successful decrypt followed by a version check; a wrong/changed password (or an encrypted payload that the current parser cannot decode) goes through the generic fallback and leaves the guard null. The base `SyncIface` then catches the parse/merge error and performs its unconditional upload, replacing the unreadable encrypted remote with this device's copy. This is reproducible when device A changes the backup password or has a different password from the remote and an automatic sync runs; it would be false only if `SyncIface` independently refuses uploads after every `fromFile` failure, contrary to the documented unconditional-upload behavior in this change.
In lib/data/store/migrations/m004_kv_to_tables.dart around line 581, address this finding:
m004 preserves per-server agent conversations and active rows whose server reference cannot be resolved, creating orphaned data that no server can reach.
In lib/main.dart around line 255, address this finding:
Legacy-file inheritance is not part of the sync lifecycle and can race the first versioned upload. `_doDbMigrate` launches `inheritLegacyRemote()` with `unawaited`; meanwhile startup/home/provider code can call `bakSync.sync`. If the versioned file is absent, the sync can upload the current local (pre-inheritance) state to `srvbox_bak_v3.json` before the legacy download/merge completes. `inheritLegacyRemote` only merges locally and never uploads the merged result, so the new remote history permanently omits the legacy servers/snippets/keys until a later user mutation happens to trigger another sync. The same race can also allow the legacy merge to modify stores while `BackupV2.loadFromStore` is assembling an upload. This would be false only if `SyncIface` serializes arbitrary calls against this separately-invoked method, which this class does not arrange.
In lib/data/store/db.dart around line 104, address this finding:
The schema's reachability CHECK accepts empty connection strings, contrary to the migration and model invariant that a server must have a usable SSH host or monitor address. `CHECK ((ssh_ip IS NOT NULL) <> (monitor_addr IS NOT NULL))` treats `ssh_ip = ''` (and likewise `monitor_addr = ''`) as configured, so a direct SQL/entity write can persist a server that has neither usable endpoint; the added schema tests cover only NULL versus non-NULL and would pass this invalid row.
In lib/view/page/server/edit/actions.dart around line 382, address this finding:
Saving a server with a duplicate name is not converted into the localized duplicate-name error: the editor awaits addServer/updateServer without catching DuplicateNameException, so the form does not remain in a clear editable state and the user can receive an uncaught/raw error instead of the required localized message.
In lib/view/page/server/edit/actions.dart around line 503, address this finding:
A server whose stored `ssh_key_id` no longer exists is initialized with `_keyIdx == -1`, and that sentinel is treated as an active-but-empty key-auth selection. Even when the server still has a valid password, saving the editor always rejects it with the `empty` toast instead of preserving password authentication or clearing the stale key reference. The same stale `-1` also makes the key-auth switch appear enabled.
In lib/data/store/migrations/m004_kv_to_tables.dart around line 195, address this finding:
Malformed nested server data can abort the whole atomic m004 transaction instead of dropping only the malformed record. For example, a server with `custom: 'not-a-map'` reaches `final custom = v['custom'] as Map?` and throws a type-cast error; similar unchecked casts exist for nested fields and child collections. Since `_rows` only catches JSON decoding and there is no per-row boundary around `_migrateServers`, the transaction rolls back all otherwise valid records and schema advancement cannot complete.
In lib/view/page/server/edit/edit.dart around line 83, address this finding:
The server editor still stores the selected private key as a positional list index, so a key rename/reorder or provider reload while the form is open can save a different key than the one displayed (or produce an invalid selection).
In lib/data/store/connection_stats.dart, address this finding:
Connection-stat ordering and pruning are nondeterministic for attempts in the same millisecond. History, the per-server window function, and the 100-row pruning subquery all order only by `timestamp`; two generated-ID rows with equal timestamps may swap order, changing which server name is selected as current, the recent list order, and which tied 101st record is deleted.
In lib/data/store/tables.dart, address this finding:
The relational schema does not constrain port numbers even though the table is now the authoritative storage and backup/restore writes can bypass UI validation. `PortForwards` only adds a CHECK on `type`; `local_port` defaults to 0 with no range check and `remote_port` is nullable with no range check. Consequently a direct `PortForwardStore.put` or a crafted backup can persist -1, 70000, or an invalid remote port, and the provider later attempts to use that invalid endpoint. This would be false only if every writer were independently guaranteed to validate both ports, which `PortForwardConfig` does not do and the store's `write` does not do.
Somewhere in the code under review, address this finding:
Deleting a private key updates `server.ssh_key_id` in SQLite via `ON DELETE SET NULL`, but does not invalidate or notify `ServerStore`, leaving cached `Spi` objects with the deleted key id. `PrivateKeyNotifier.delete` calls `Stores.key.delete` only; `PrivateKeyStore` has no dependent-server invalidation, while `ServerStore.fetch()` returns its cache until one of its own writes calls `invalidate()`. Thus an already-loaded server list can continue resolving the removed key id and attempt to use a key that no longer exists (and the UI will not reflect the reference being cleared) until an unrelated server write/reload. This is false only if every key deletion is followed by a guaranteed global server reload before any server read; the shown deletion path does not do that.
In lib/data/model/app/bak/backup2.dart, address this finding:
A v2 remote merge is not atomic across stores, so a failed/interrupted sync can leave a partial restore that is then eligible for upload. `BackupV2.merge` commits keys, servers, snippets, port forwards, containers, and only later history/settings through separate store calls; unlike the legacy `Backup.merge`, there is no enclosing transaction. For example, a process interruption or SQLite error after `Stores.key.merge`/`Stores.server.merge` but before the remaining sections leaves references and records from different sides, and the next sync serializes that partial local state. This is false only if every `Stores.*.merge` implementation participates in one shared transaction despite the absence of a transaction around these calls.
In lib/view/page/snippet/list.dart, address this finding:
The split snippet pane identifies the open record by its mutable name, so renaming a snippet through the new ID-based notifier drops the pane selection and editor on the next provider rebuild instead of continuing to edit the same record.
In lib/view/page/private_key/edit.dart, address this finding:
Private-key persistence failures other than duplicate names are shown directly with e.toString(), allowing raw SQLite/storage diagnostics to reach the user and then rethrowing from the save callback; this violates the user-facing migration/storage error contract.
In lib/view/page/private_key/edit.dart, address this finding:
Private-key save still exposes raw SQLite exception text in the editor instead of a user-facing/localized error for database failures.
In lib/data/store/schema.dart, address this finding:
The migration API documentation is now false for the new storage chain: `SchemaMigration.apply` still says every migration rewrites Hive stores in place, while `KvToTablesMigration` operates on SQLite `kv` and is the only registered migration after `HiveImport`. This misdirects future migration authors toward the wrong engine and conflicts with the architecture guidance that Hive is read-only compatibility input.
Somewhere in the code under review, address this finding:
The `SchemaMigration.apply` API documentation says migrations “rewrite the local Hive stores in place,” but the only registered migration (`KvToTablesMigration`) runs after Hive import and rewrites SQLite `kv` into SQLite entity tables. This is materially misleading for anyone implementing the next step: following the contract would target the retired source engine, and it also contradicts the architecture documentation's SQLite migration chain. The claim would be false only if another caller passed a Hive-backed migration list, which the inspected startup and tests do not do; update the interface comment to describe the current storage engine (or explicitly say the engine is migration-specific).
In test/fixtures/README.md, address this finding:
The fixture README's box counts are inconsistent with the artifacts and the release test: it labels v1.0.1466/1480 as having 8 boxes and v1.0.1491 as 9, while each directory contains those encrypted boxes plus `conn_stats_index.hive` (9 files for 1466/1480 and 10 for 1491), and the test explicitly treats the plaintext index as a box/file. A maintainer using the README to verify a regenerated fixture can therefore accept a missing legacy box or misread the expected count. This would be false only if “Boxes” is explicitly defined as “encrypted data boxes excluding the index”; the README currently calls the index a box in its contents and does not define that exclusion. Clarify the count (encrypted boxes vs total files) and update the table.
## Previously reported and still present (10)
In lib/data/store/migrations/m003_hive_to_sqlite.dart around line 225, address this finding:
A destination write failure is treated as a successfully opened/imported box. `_importBox` logs `into(...) == false` but still returns `opened: true`; the caller adds that box to `done`, and when all boxes are otherwise readable it writes the import marker. A transient SQLite/storage failure therefore permanently marks the box complete even though rows are missing, with no retry on later launches.
In lib/data/store/migrations/m004_kv_to_tables.dart around line 150, address this finding:
Duplicate legacy private-key identities overwrite the remapping entry, so servers can be attached to the wrong key. `_migratePrivateKeys` deliberately permits duplicate records by generating unique names, but stores only `ids[oldId] = id`; if two imported rows have the same `value.id` (or both fall back to the same key identity), the later key wins and every server referencing that old identity is rewritten to the later key rather than preserving the original association. The same ambiguity exists for server IDs: a duplicate non-empty `server.id` causes the second INSERT to violate the primary key and rolls back the migration. This would be false only if the legacy KV format guarantees identity uniqueness independently of its store key, a guarantee the migration comments explicitly say was not enforced for private keys.
In lib/data/store/migrations/m004_kv_to_tables.dart around line 211, address this finding:
A malformed/duplicated server record can roll back every migration rather than being dropped. `_migrateServers` inserts any non-empty legacy `v['id']` directly as the new primary key; if two KV rows have the same id (for example a corrupt row whose KV key differs from its duplicated embedded id), the second `INSERT INTO server` raises a UNIQUE constraint. Because `apply` wraps all stores in one transaction and does not catch per-record SQL errors, valid keys and servers already inserted are rolled back and the schema remains v4. This would be false only if the pre-m004 data contract guarantees embedded server IDs are unique, despite the migration explicitly handling malformed/old records and not validating that invariant.
In lib/data/store/entity_store.dart around line 330, address this finding:
Incremental merge ignores the new per-row `rev`, so two edits made in the same millisecond do not have last-write-wins semantics. `EntityStore.merge` skips an incoming record whenever `bakTs <= current[id]`; because `timestamps` carries only `updated_at` and not `rev`, equal timestamps are treated as already handled even when the incoming row has a later revision. A peer that edits twice within one millisecond can therefore lose the later edit based solely on merge arrival order.
In lib/data/store/private_key.dart around line 68, address this finding:
Restoring a backup can detach or skip servers when a private key is reconciled by name to a different local id. `PrivateKeyStore.reconcile` changes an incoming key's id to the existing same-name key, but `ServerStore` later writes the incoming `Spi` unchanged, whose `sshKeyId` still points to the backup key id. The server table has a foreign key to `private_key(id)`; with foreign keys enabled this update/insert fails (and `EntityStore.merge` skips that record), so a valid server from the backup is omitted instead of being rewritten to the reconciled key id.
In lib/data/store/private_key.dart around line 69, address this finding:
Private-key reconciliation does not rewrite incoming server references, so a restore can silently drop every server that uses a same-name key with a different ID. If the local database has key `(id=K2,name=foo)` and the backup has `(id=K1,name=foo)` plus a server whose `ssh_key_id` is K1, `PrivateKeyStore.reconcile` maps the key to K2, but `BackupV2.merge` passes the server JSON unchanged; `ServerStore.write` then violates the `server.ssh_key_id → private_key.id` FK and EntityStore.merge catches/skips that server.
In lib/data/store/migrations/m004_kv_to_tables.dart around line 80, address this finding:
An unreadable known-host JSON value is deleted even though `_migrateKnownHosts` deliberately returns without recovering it. On malformed JSON, the function logs and returns, but `apply` unconditionally executes DELETE for `sshKnownHostFingerprints`; the migration then advances to v5, irreversibly dropping all known-host fingerprints instead of following a skip/retry policy.
In lib/data/store/container.dart around line 164, address this finding:
Container settings are not represented as syncable child records and are not carried through backup merge with per-setting last-write-wins or deletion semantics. `ContainerStore` stores host/runtime rows without updated_at/rev, while its restore methods only add supplied nonempty hosts and set a runtime; restoring a newer state that removed a host/runtime leaves the old row in place. Thus a restore/sync can retain deleted container configuration and cannot resolve concurrent container edits by revision.
In lib/data/store/db.dart around line 262, address this finding:
Port-forward rows accept invalid port values: the relational table constrains only `type`, while `local_port` has default 0 and neither local nor remote port has a range check. A direct SQL insert, backup merge, or `PortForwardStore.put` can therefore persist negative or >65535 ports, and the model/provider can later return them as valid configurations.
In lib/data/provider/private_key.dart around line 43, address this finding:
A server cache can retain a deleted private-key reference. `PrivateKeyNotifier.delete` deletes the key row but only updates the key provider state; it does not drop/invalidate `ServerStore`'s cached `Spi` list or reload the server provider. Any code reading the already-cached server continues to expose the old `ssh.keyId` until an unrelated server write/reload, so key deletion leaves model/cache state inconsistent with the foreign-key SET NULL result in SQLite.

Legacy servers with both SSH and monitor credentials are silently dropped by the migration, violating lossless compatibility. `_migrateServers` treats `hasSsh == hasMonitor` as unrepresentable and skips the row; the prior model could store both and `Spi.toJson` can carry both. Upgrading such an installation removes the server and all of its nested data rather than preserving it or reporting a recoverable conflict.

In lib/data/model/app/bak/backup2.dart, address this finding:
Container settings are not merged losslessly: restoring a newer server state cannot remove a host/runtime child that is absent from the backup, and an older container payload is applied even when the corresponding server record is rejected by LWW. For example, device A deletes a server's Docker host (or changes its runtime), then merges a backup containing the older server/container data; `BackupV2.merge` applies `restoreOne` to every container entry unconditionally, while `restoreOne` only inserts values that are present and never deletes missing `host_*` or `runtime` rows. The deleted/changed child therefore remains locally and can continue to affect connections after the server merge. This is introduced by the new child-table backup path; it would be false only if container entries were guaranteed to be complete, timestamped, and filtered against the server merge before this method is called.

A BackupV2 merge is not atomic across the relational roots and dependent sections. The entity stores commit each `merge` independently, then container writes commit independently, while history/settings are launched in a separate `Future.wait`; if a later section fails (for example a malformed or constraint-invalid history/settings entry, or an interrupted process), keys/servers/snippets/port forwards and possibly container state have already been committed. This violates the restore invariant that a failed merge must not leave partial relational state; only the legacy `Backup.merge` uses one transaction for the whole restore.

A backup merge that changes only container settings does not notify/reload the server provider, so the UI can keep showing stale server data until an unrelated server reload. `restoreOne` mutates the child tables and calls `Stores.server.invalidate()`, but `BackupV2.merge` only explicitly reloads `serversProvider` when `serversChanged` is true; it does not use the server store change stream to reload the provider. Since container settings are deliberately represented as children of a server, this is a stale notification/cache path for exactly the settings that were moved into the relational schema.

* docs: bring TODOS.md back in line with what the code says
Checked every section against the tree. Three things had drifted:
- The entity tables (#1322) went past what the "Hive → SQLite" plan said would
stay key-value, and drift came back for the DDL. Both are recorded, with the
superseded reasoning kept and marked rather than rewritten.
- `sandbox_import.dart`'s `app.db` special case was listed as dead code. It is
not: both sites now key on `SqliteDb.fileName`, and the `-shm` skip matches
by exact name so a user's own file still comes across.
- "Android / Linux / Windows unverified" still holds, and for a sharper reason
than the entry gave: `build.yml` only runs on a `v*` tag, and the last such
run predates `hook/build.dart`, so no CI run has exercised the hook path on
any platform.
* fix(ios): keep Activity.request off the main thread, and stop lldb on SIGUSR1
`Activity<T>.request` is synchronous and makes a blocking XPC round trip to
`liveactivitiesd`. Running it straight from the MethodChannel handler put that
wait on the main thread, so the UI froze until the daemon answered — most
visibly on the first activity of a run, which is what starting Alpine
requests.
LiveActivityManager becomes an actor. The blocking request hops to a dedicated
serial queue rather than parking a cooperative-pool thread, and `current` is no
longer read and written by every detached Task with nothing ordering them. The
duplicated localization and ContentState construction collapse into one
`contentState(from:)`.
All three MethodChannel cases now answer from inside the Task instead of after
starting it: TermSessionManager's drain loop awaits each call, and that await
is what orders successive updates.
Separately, the iOS Linux engine interrupts its guest threads with SIGUSR1 — on
signal delivery, on task exit, and on every timer tick — and lldb stops the
whole process on each one by default, which reads as the app hanging the moment
Alpine starts. The scheme now points at a checked-in lldbinit that sources
Flutter's generated one (required, and what the tooling's migration checks for)
and passes SIGUSR1/SIGTTIN/SIGPIPE through, as iSH's own ish-lldb.lldb does.
* fix(android): compile wakelock_plus at the Kotlin 2.1 language level
Its pigeon output carries no `package` declaration, so `Wakelock.kt`
reaches the generated types with `import IsEnabledMessage` — an import
from the root package, which Kotlin 2.2 rejects. Release builds failed in
`:wakelock_plus:compileReleaseKotlin`.
Neither end moves: every published version from 1.3.2 to 1.7.0 is written
that way, and Flutter's gradle plugin refuses a KGP below 2.2.20, so
there is nothing to upgrade or downgrade to. Scoped to that one module so
the app's own Kotlin is not held back.
* fix(ui): follow the theme on the Agent tab and its history rail
Both painted `colorScheme.surface`, which `ThemeDataX.toAmoled` does not
override — it replaces `scaffoldBackgroundColor`, the dialog, sheet and
card slots, and leaves the scheme alone. So under an AMOLED theme this
was the one tab that stayed Material grey, rail included, while every
page around it went black.
The tab now shows the `Scaffold`'s background like the terminal and file
tabs do, and the rail is transparent so it shows whatever it sits in —
that background in a column, the sheet's own in a sheet.
* fix(ui): let a page pushed in a tab animate across the status bar
The shell's `Scaffold` held an empty box the height of the status bar to
push the tabs clear of it. A page pushed inside a tab lives in `body`,
under that box, so the strip stayed put while the page animated below it
and entering or leaving a page read as two pieces moving separately.
The box is gone and the inset lands on the tab's own content, inside
`NestedNavigator.rootBuilder`. That placement is the point: a pushed page
is a sibling route, outside the `SafeArea`, so it reaches the top of the
window. Wrapping the navigator instead would inset the pushed page too
and put the seam back.
Not in each tab either — three of them put a `Scaffold` inside a pane
splitter, and the splitter's divider is above any app bar that could have
spent the inset. Doing it per tab left that divider crossing the status
bar in the terminal tab.
The bottom bar keeps its seam and is left alone: it is chrome the tabs
share, and a page opened in a tab is meant to leave it in place.
* docs: record what Android verified, and two traps that cost a build
TODOS.md:
- Android is off the unverified list. `dart run fl_build -p android`
produces the three split-per-abi packages, and the arm64 one runs on an
Android 16 phone and an emulator. `RustLib.init()` is before `runApp`
and throws on an FRB mismatch, so a clean start is evidence the hook
built a loadable `aarch64-linux-android` dylib. Linux and Windows are
still unverified, and CI has still never run the hook path.
- The Hive to SQLite migration is verified on a device, not just in
`flutter test`: the v1466 fixture through the 1491 build gives the same
counts the unit test asserts, and the released 1466 APK upgrades in
place. Two things worth keeping: do not launch the old build first, it
rewrites the boxes; and `store.db` shares the Hive key, so a planted key
makes the result readable off the device.
- The wakelock_plus workaround, with the condition for deleting it.
CLAUDE.md: `flutter clean` deletes the iOS Linux engine, which is built
out of tree under `build/`. Nothing in the checkout looks different
afterwards and the next iOS build fails with three missing-`.a` linker
lines that name no cause.
* fix(ios): revert the custom LLDB init file, which stopped debug launches
bcc7b1a8 pointed the Runner scheme's customLLDBInitFile at a checked-in
ios/Flutter/lldbinit that sourced Flutter's generated one with
`--relative-to-command-file`. That flag only resolves when the commands are
being sourced from a file, which is not how `flutter run` feeds lldb, and
`--stop-on-error false` swallowed the failure. So flutter_lldb_helper.py never
loaded, the NOTIFY_DEBUGGER_ABOUT_RX_PAGES breakpoint was never set, and the
Dart VM could not get an executable page: debug builds stopped at the launch
screen with nothing printed.
Profile mode on the same device launched fine, which is what put the fault in
the debug-only lldb path rather than in the Live Activity change from the same
commit. That change stays — profile exercises it too, through the
`stopLiveActivity` that `_initApp` awaits before `runApp`.
Passing SIGUSR1 through for the ish engine is still worth having, but not at
the cost of the scheme. It belongs in ~/.lldbinit or an Xcode breakpoint
action, neither of which is shared.
* docs: record the SIGUSR1 trap that reads as an Alpine launch crash
`flutter run` installs a stop hook that backtraces every thread and detaches
the moment the process stops, and iSH raises SIGUSR1 constantly, so the two
together end a debug session on the first guest signal. In debug mode detaching
drops the breakpoint the Dart VM needs for an executable page, so the app goes
with it — and the `bt all` that comes attached to the report is the hook's
output, not a request.
Also records that the scheme's customLLDBInitFile is the wrong place to fix
this: `flutter run` on Xcode >= 26 never reads it.
* fix(android): run proot with --link2symlink so hard links resolve
Android refuses `link()` inside an app's own data directory, and `-0`
does not help: it makes the guest believe it is root while the uid the
kernel checks is still the app's. A package whose tar carries hard links
fails on exactly those entries and on nothing else — `apk add go` reports
`Permission denied` for `usr/bin/gcc-{ar,nm,ranlib}` and `usr/bin/ld.gold`
and leaves a gcc with no drivers, while the other 31 packages install.
termux/proot carries the extension for this, which is why the build uses
that fork rather than upstream; it was simply never passed. A hard link
becomes a symlink, which these tools are indifferent to — each dispatches
on `argv[0]`.
The rootfs test asserted a package install, but the package was curl,
which has no hard links, so it said nothing about this. It now creates one
directly: cheap next to the 357 MB `apk add go` pulls to reach the entries
that fail, and it is the capability rather than one package's use of it.
Verified both ways on an emulator, which refuses `link()` the same way a
phone does — without the flag the new assertion fails with an empty read.
* fix(ios): stop forwarding a delegate callback FlutterAppDelegate has no imp for
`application:didDiscardSceneSessions:` is an optional UIApplicationDelegate
method and FlutterAppDelegate does not implement it, so the `super` call
raised NSInvalidArgumentException and terminated the app. It fires when the
user closes the app from the switcher, which is why it took a reinstall over a
still-listed session to show up.
`applicationWillTerminate:` is the opposite case — FlutterAppDelegate does
implement it, and it is how registered plugins hear the app is going away —
and that one was missing its `super`. Both checked with `otool -oV Flutter`:
the first selector appears only in the protocol's name table, the second has
an imp.
* fix(ui): bump fl_lib for the rail row that grew a trailing button
Opening a session on the terminal or file tab moved the target's name into the
running section, where it gets a close button — and the row went from 35pt to
58pt, because a Material control takes a 48pt tap target regardless of the
constraints set on it. fl_lib now overrides that on the row itself, so the
Agent's history panel is fixed too.
* fix(ios): carry the guest console as bytes, not through a String
`IosRootfs.read` answered `String.fromCharCodes`, which reads each byte as one
code unit, and the terminal encoded that back to UTF-8 — so every byte of a
multi-byte character became two. `中` (E4 B8 AD) reached xterm as six bytes and
drew as `ä¸`. The tty echoes what is typed through the same path, so it was
visible while typing, before any command ran.
Both directions are bytes now. The terminal keeps UTF-8 decoding state across
chunks, which is more than this layer can do when each read is a separate call
and a character can straddle two of them.
`IshExec` does need text, and uses a chunked decoder for the same reason — it
holds an incomplete tail back until the rest arrives. `_SinkOf` exists because
`dart:convert`'s own sinks either buffer to `close` or want a `StringSink`.
Not verified on a device yet.
* fix(ios): stop init from fork/exec-ing a shell as fast as it can
`sbm_ish_boot` ran init as `while :; do /bin/sh; done`. Init has no tty and no
stdin — a pty is what `sbm_ish_open` gives each session, not something init
gets — so every one of those interactive shells read EOF and exited at once
and the loop started another. A fork/exec storm, inside an interpreter, for as
long as the machine was up.
It made the whole app slow from the moment Alpine was opened, and closing the
last terminal did not stop it, because the machine deliberately stays up. It
also starved hot restart badly enough to look like a hang.
Init only has to exist and never exit, so it sleeps instead, wrapped in a loop
so a signal cutting the sleep short cannot end it. Verified on device: the app
is no longer slow in debug with a terminal open, hot restart works again, and
the guest's highest pid stops climbing.
Two Dart costs on the same path, both paid per frame per session:
- `IosRootfs.read` malloc'd and freed an 8 KB buffer on every poll, including
while the shell sat at a prompt. Allocated once and kept.
- The poll ran at 16ms for the life of the session, which outlives the page —
it kept running with the terminal off screen and the app on another tab. It
now relaxes to 120ms after eight empty reads and snaps back on the first
byte.
- `IosRootfs.isAvailable` called across FFI on every read, and `tab_add.dart`
reads it three times per build. The answer is fixed when the app is built.
* refactor(l10n): trim three labels to what they name
"Edit virtual keys" is a row that opens a page; the verb belonged to the page,
not to the name of the thing. "Known host keys" names the keys when what the
page manages is the hosts they belong to. "Full screen mode" carries a word
that says nothing the other two do not.
Reworded in each of the fifteen locales rather than in English with the rest
left to follow — `Modifier les touches virtuelles` → `Touches virtuelles`,
`Полноэкранный режим` → `Полный экран`, `已信任的主机密钥` → `已信任的主机`.
The `editVirtKeys` key no longer matches its value. Renaming it means touching
every locale and every reference, so it is left as it is.
* refactor(settings): fewer rows, and seams that match the rest of the app
Four things, all in the settings page.
**A group's own settings are General, not Settings.** `app`, `server` and
`terminal` each carried a leaf named "Settings", inside a page called
Settings — three rows with the same name, and the word said nothing the parent
had not. `general` is new in fl_lib, translated in all fifteen locales.
**Backup is two pages.** Keeping data somewhere else and bringing data in are
different questions that shared a page because both move data. The page was
already built as two lists under two headings, so the split is a `BackupSection`
and no new layout. The standalone `/backup` route still shows both, side by
side, with its own headings: the DMG notice opens it directly and there is no
menu around it to say which half you are looking at.
**Three orderings are one page with tabs.** "Server order", "detail page widget
order" and "sequence" read alike as three menu rows — you had to open one to
find out which list it held. Side by side as tabs each is named by what the
other two are not. The three pages are unchanged and still routable; the server
settings page still links straight at the last of them, where three tabs would
answer a question nobody asked. Its duplicate rows for the other two are gone.
**Seams.** Two `VerticalDivider`s used Material's default colour, which is
drawn for a light background and reads as a bright line on a dark one — they
sit at the same corners as the one `AdaptivePanes` draws through `Hairline`.
And the content routes were transparent: the pages under them are `embedded`
and drop their own `Scaffold`, so during a transition each route showed the
one it was covering.
* chore(ish): move the fork's gitlink onto the merged upstream sync
lollipopkit/ShellBox#1 landed on main as 17de9b99, carrying the two
upstream commits that apply to this fork — the /proc/pid/mem show op and
the warning sweep, the latter with sigusr1_handler's signature corrected
back to (int) because kernel/init.c installs it as a sa_handler.
Its static-libs release is published, so scripts/ensure-ish-libs.sh has
something to fetch for this revision.
* feat(ios): fetch the Linux engine's static libraries for the gitlink's revision
The three .a files the Runner target links were only ever produced by
running scripts/build-ish-ios.sh by hand, and nothing in the build said
so: ios/Flutter/Ish.xcconfig hands their paths to the linker through
OTHER_LDFLAGS, and when they are absent the build stops with three
'No such file or directory' lines that name the files and not the
reason. Two ordinary ways to get there — building for the device and
then running the simulator, since each target has its own build-<arch>
directory, and 'flutter clean', which removes build/ and takes them with
it while leaving a checkout that looks untouched.
A new Runner build phase runs ahead of Flutter's own and fetches the
release the fork publishes for the submodule's checked-out HEAD, falling
back to a local build when there is no such release — the case while the
engine's own source is being worked on. The gitlink is this repository's
only statement about which revision of the engine it builds against, so
binding the download to it is what keeps the libraries and the headers
from drifting apart; the sha they were fetched for is recorded beside
them, because 'git submodule update --remote' otherwise leaves the
previous revision's libraries where they are still found.
CI opts in the same way a development machine does, by writing
IshLocal.xcconfig, rather than by moving Ish.xcconfig's SBM_ISH=0
default. It installs no toolchain: iOS CI now links the engine, and if
the download finds no release the gitlink points at an unpublished
revision and the build says exactly that.
* feat(linux): choose the guest's distribution, mirror and resolvers
The guest was Alpine in the settings' own words and in every constant
behind them. Nothing could be pointed elsewhere, which is how a device on
a network that cannot reach dl-cdn.alpinelinux.org ends up with a Linux
it cannot install packages into and no setting that says so.
Settings, under Terminal > Linux — named for Linux and not for the
distribution, since which one is installed is now a thing that changes:
- the distribution, from LinuxDistro
- its mirror, kept per distribution so switching away and back does not
drop what was typed. Empty restores the distribution's own default
- the resolvers written to /etc/resolv.conf, which are not per
distribution: that is the network the device is on
Saving either of the last two rewrites the file in a system already on
disk. Both are seeded at install and never again, so without that a
mirror changed afterwards would only take effect on the next install —
which on iOS means deleting everything apk ever put there.
LinuxDistro carries what differs between distributions: label, version,
branch, default mirror, digest, the tarball URL's shape, and the path and
format of the file the package manager reads. Its switches are
exhaustive, so a second entry is a case here and an arm in each of them.
The digest stays pinned in code while the mirror is a setting: a mirror
decides where the bytes come from and never which bytes are accepted.
What is on disk is now recorded rather than assumed. The marker holds the
distribution and the version, so switching knows what it replaces and an
update offer knows what the version on disk is a version of. Both older
formats — a bare version, and an empty file — read as Alpine, which is
what wrote them.
iOS asked whether a system was installed with bin/busybox and
etc/alpine-release, which are Alpine's. Replacing them with bin/sh and
etc/os-release needed a second change: Alpine's /bin/sh is an absolute
symlink to /bin/busybox, a path inside the guest, so File.exists()
answers false for a tree that is perfectly fine. Every existing install
would have read as absent and been offered for reinstall, taking
everything in it. looksUnpacked() does not follow links, and a test locks
that.
* feat(linux): choose the shell an interactive terminal starts
Which shell a session gets was hardcoded twice — `/bin/sh` in
`sbm_ish_open` and again in `AndroidRootfs.enterCmd`. Alpine ships no
`chsh`, which is the usual way to change it and also a red herring: the
guest has no `login` and nothing in it reads `/etc/passwd`, so the shell
is this app's choice and no other. A setting is the whole answer.
`sbm_ish_open` takes it as a parameter now, NULL or empty meaning
`/bin/sh`. A shell it cannot exec falls back to `/bin/sh` and says so to
syslog, rather than handing back a terminal that dies on sight — the
setting is checked before it is stored, so reaching that fallback means
the guest changed underneath it.
Interactive sessions only. A one-shot command keeps `/bin/sh` on both
platforms, because the app and the Agent write POSIX and parse what comes
back: fish is not a POSIX shell, and a status script or an `&&` run
through the user's choice would fail in ways that read as the remote host
being broken.
The path is checked for shape and then for being there, against the tree
that is actually installed. Neither failure is visible afterwards — the
engine answers ENOENT from inside `sbm_ish_open`, and nothing puts that
on screen. Existence is checked without following links, since Alpine's
shells are links to busybox by a guest-absolute path that does not
resolve host-side.
Also records, in TODOS.md, what was established about multiple kernels
and about background execution: iSH's kernel state is file-scope global
so a second instance means a fork that diverges structurally, real
isolation on iOS needs a second process and an App Store app has none,
and the only sanctioned way to keep running in the background is
BGContinuedProcessingTask on iOS 26 — which the verification iPad, on
18.7.8, cannot use.
* feat(linux): several systems installed at once, each in its own root
One kernel, many roots — which is what a container is, and as much as iOS
allows: an App Store app cannot fork, so a second *kernel* would need a
second process it has no way to get, and iSH keeps its state in file-scope
globals besides. So the systems share a PID space, a network and a pty
numbering, and can see each other through /proc. That is the deal, and it
is written down in the header rather than implied.
The machine's root is now a container of trees, one subdirectory per
system, and nothing runs at that level. sbm_ish_attach mounts one
system's /proc, /dev, /dev/pts and /dev/shm — idempotent, so opening a
terminal in a system that is already up costs a strcmp. sbm_ish_open
takes which one to run in and points the task at it before anything
opens a path, since attach_stdio names /dev/pts/N and that has to mean
this system's devpts. Safe because construct_task gives every task its
own fs_info (kernel/init.c:107) rather than sharing init's, so the root
of one session is not the root of another.
Init lives inside a system rather than at the container root, which holds
no /bin/sh to start it with, nor the loader that shell names.
A profile is a directory plus the marker in it, and nothing else: no
table, no setting listing what exists. So one deleted from disk cannot
linger in a list, and a list cannot promise a tree that is not there. The
id is that directory's name, generated — keying it by distribution was
the first attempt and it made two Alpines side by side impossible, which
is the case this exists for. The distribution is a field of the marker,
the label is another and is the user's.
Selecting is not switching. Nothing is deleted, sessions already running
stay where they are, and the settings page is a list with add, rename,
update and delete rather than a picker that replaces what is there.
* chore(ish): bump the engine to cdab02e2
Brings in the audit branch (ShellBox #2): the fakefs error contract, the
poll and epoll registration lifetimes, the AF_LOCAL handshake no longer
putting a struct fd * on the wire, and unit tests for the leaf logic
each of those changed.
libs-cdab02e23c0eb897d0bd89ce6c8aa04c3d8e9d8c is published with all
three archives, so ensure-ish-libs.sh fetches rather than building. The
previous revision's libraries in build/ are replaced rather than reused
— that is what the .ish-libs-sha stamp is for, and a gitlink bump is
exactly the case it was added to catch.
* feat(linux): a chsh for systems that have none, writing what the app reads
Alpine ships no `chsh` — it is in `shadow`, which a minirootfs does not
carry — and installing the real one would not have helped: it edits
/etc/passwd, and nothing in this guest reads that. There is no `login`
here. So the stand-in at /usr/local/bin/chsh writes the file that does
decide, and is a shell script.
/usr/local/bin comes before /usr/bin in the PATH the engine sets, so it
also shadows the real one for anyone who installs `shadow` later — the
outcome to want, since that one edits a file with no readers and reports
success. A chsh already there that is not ours is left alone: overwriting
a package's file would have apk reporting a modified system.
The shell moves out of the app's settings and into the guest, at
etc/serverbox/shell. One file is the answer for both sides, so there is
no rule about which store wins. It falls out per system, which is right:
a shell is a path to a file inside one tree, and /usr/bin/fish being
installed in one says nothing about another. Read when a terminal opens
rather than from anything cached, so a chsh run a second ago is in force.
The script is tested by running it. It ships to users, is edited by
nobody who can try it where it runs, and a syntax error there surfaces as
"chsh does something odd" and nothing else — test/chsh_script_test.dart
is `sh` on the host reading the same bytes, over every branch including
the ones that must refuse without writing.
* feat(linux): a terminal names the system it is in, so two can run at once
The engine has held several systems since the container root landed; the
terminal tab could not say which one it wanted. LocalSource carries a
profile id now, and that is the only thing telling two of these tabs
apart — same device, same kind of source — so it has to be in the id that
a saved set stores and a backup carries.
Null there means "whichever is selected", resolved when the shell opens
rather than when the tab is made. That is what a set saved before this
existed says, and what it meant: there was one system, and the one system
there is is the selected one. A set naming a profile this device has not
got is skipped like an unknown server — restoring a backup onto another
device is exactly how that happens.
Opening asks which, once there is more than one. Opening "the selected
one" would have made the second unreachable from the terminal tab, and
they run at once, so it is a choice and not a switch. Deleting closes the
tabs of that system and leaves the others, which is the point of them
being separate.
Both backends take the id: on iOS it reaches sbm_ish_open, on Android it
picks proot's -r. proot is a host process per session, so nothing had to
be coordinated there beyond passing it down.
* fix(ui): settings content starts at the top, and the tabs float over it
The narrow settings pane read its insets from a context above the
Scaffold, where padding.top is still the status bar the app bar already
covers. It handed that back to the page, whose own SafeArea applied it a
second time, so every embedded page began a status bar below the top —
and the home indicator was counted twice at the foot.
The floating level tabs now sit over the content rather than on a strip
taken out of it: the bar is translucent and blurs what passes behind,
and the room a list needs to bring its last row clear of it arrives as
scroll padding (context.padBottom) instead of as a shorter page. Its own
way back is gone; the title bar has one, and two on a screen was the
same move twice. The shadow goes back to an elevation — one soft shadow
at 16% read over a full page and vanished over the bare background of a
short one.
The SSH page's background moves behind the whole Scaffold, so the
virtual keys are drawn on it too. They painted the terminal theme's
background, which is not what the terminal is drawn on — TerminalView is
given backgroundOpacity: 0 — and stood out as a strip of another colour.
atLeastOneTab goes with them: nothing has used it since the home tabs
page started reporting serverTabRequired instead.
* chore(ish): bump the engine to e857383f, for chroot-aware path resolution
lollipopkit/ShellBox#3. Two places in the engine answered in the
machine's terms to a task that cannot name them, and both surface the
moment a session is rooted at a subtree — which is what this app started
doing when it began holding several Linux systems under one machine root.
An absolute symlink target restarted from the machine root, so Alpine's
`/bin/sh -> /bin/busybox` resolved to a `/bin` the task cannot see;
`getcwd` reported `/alpine` for what was that task's own `/`. Without the
first, nothing in a profile could exec at all.
Both are identity for a task rooted at the machine's own root, so nothing
on the single-root path this app shipped before changes.
* docs(todos): iOS delivers no key repeat, so a held key never repeats
Measured rather than inferred: a backspace held 4.5s produced one
KeyDownEvent and one KeyUpEvent and nothing between. The bursts that look
like repeat are discrete presses — every Down has a matching Up ~80ms
later, which auto-repeat does not do.
So `KeyRepeatEvent` never arrives on this path and the half of xterm's
guard that tests for it is dead code on iOS. The fix has to be a timer
the app runs itself; where it goes is a trade-off the note states.
* feat(ui): a line for the session, and a walkthrough for the virtual keys
The tab strip gave each tab a fixed 60-90pt on a phone, which is about
six characters once the close button and the insets have taken their
share, and a third session already overflowed a row spending 43% of its
width on a leading button, three dividers and the actions. It replaces
that with the session on screen named in full, its position among the
rest, and a sheet holding all of them — see the fl_lib commit. Both tabs
feed it what a row can now say that a tab could not: an address for a
terminal, a path for a browser.
The wrapper both pages put it in is what the Scaffold measures, so it is
told the height rather than left on kToolbarHeight. That default was
already giving the old 48pt strip 56.
The virtual keys get a walkthrough instead of the paragraph in a dialog
that nobody reads. It floats over the terminal and stops where the keys
begin, so the row it is describing stays lit while the page behind it
dims, and the keys outside the step's group fade with it. Three kinds
and not seventeen keys: which of them type, which move the cursor, and
which leave the terminal altogether.
Holding a key is what keeps paying off after that — VirtKeyX.help has
only ever been visible in the settings list, and now it is on the key
itself. snippet and tmux grew one so that all six shortcuts answer.
Two things worth naming:
- Every restored tab lays out, not only the one landed on, so the
walkthrough waits for its own page to be the visible one. Without
that it is spent on whichever tab the PageView built first and the
user meets a flag already set.
- The server list's own title button rippled across the whole row.
Flexible hands down loose constraints and the Row inside it was left
at MainAxisSize.max, so it took every point the tags had not claimed.
* feat(agent): the header names the conversation, and opens the list
It was the app's name beside a badge, with a history button and a
new-conversation button on the right — three ways of saying "Agent" and
none of saying which conversation you were in. Now it is the line the
terminal and file tabs carry: which one this is of how many, its whole
title, and a chevron.
Tapping it opens the conversation list, which is where switching,
renaming, deleting and starting one already live. So both buttons go:
the history one was a second way to that same sheet, and the plus was a
third thing on a row that never said what it was about. Refused while a
tool is running, for the reason the list's own rows are — switching away
leaves the execution appending to whichever conversation is active by
then.
Beside the history column there is nothing to open, that column being
the list, so the line is a label there. It names the conversation
regardless, which is what the terminal and file tabs' wide bars do.
The floating shell keeps its two buttons. It has neither this line nor a
column, and they are its only way to either.
* fix(ui): tighten the vertical rhythm of the card grids
The four tabs built on MasonryList — servers, the terminal and file
pickers, snippets — drew 12pt above the first card and 16 between any
two, because a Card's own 4pt margin is added to the grid's padding and
spacing rather than replacing them. Now 8 and 12; see the fl_lib commit
for the numbers and the reason they were not the ones written down.
PageColumns had the grid's spacing written out a second time, under a
comment about the two agreeing. It reads the constant now, so they do.
* feat(linux): the systems on this device, as chips over the picker
The terminal picker asked which system to enter with a dialog on the way
in, and the settings page hid what could be done to one behind a
`more_vert`. Several can run at once, so which one to open is something
to see and tap rather than a question to answer before the page will do
anything: a section pinned over the grid, one chip per system, with the
one a profile-less tab would land in marked.
Above the grid and outside it — one subject with several members, where
a card each would have put them among the servers as though each were
another machine. It is all this one.
`installRootfs` grew `another` and `label`, because its early return
meant "there has to be one to enter" and was silently answering "yes"
to the two callers that mean the opposite: adding another and replacing
one both install *although* something is there.
Settings shows the actions instead of a menu holding them. Two of them
is a tap that only ever reveals the same two, and the row no longer
keeps a long-press nothing announced.
* fix(ssh): one Cmd+V pastes once, and a key reaches one terminal
`TerminalView` already binds every clipboard chord — Cmd+C/V,
Ctrl+Shift+C/V and Ctrl+V, in `defaultTerminalShortcuts` — and its
intents call the same `onPaste`/`onCopied` this page hands it. Handling
them again in the page's own `HardwareKeyboard` handler meant two paths
each seeing the event, so one Cmd+V pasted twice. The page's copy goes,
and `clipboard_chord.dart` with it; plain Ctrl+C stays bound by neither,
which is what keeps SIGINT reaching the shell.
The handler is global and every open terminal keeps one — the pages stay
alive, that is what `wantKeepAlive` is for — so it now refuses unless
its own page is the visible session. An Escape typed in one terminal was
reaching all of them, and every key was handled once per tab.
Pasting goes through `Terminal.paste`, which brackets the text when the
program asked for that (DECSET 2004). `textInput` does not, so an editor
auto-indented every line of a paste and a shell ran the newlines.
* chore(pty): bump the fork to 8af306f, which skips non-code asset hook phases
* chore(ish): bump the engine to ccff02a0, for the task-root follow-ups
* chore(ish): bump the engine to 2c3bf993, the merged task-root fixes
The fork's PR landed, so the two commits this branch was carrying —
e857383f and ccff02a0 — are on its main, with the x86 emulation fixes
that went in with them: SSE MIN/MAX taking the source on a tie, f80_gt
answering ordered comparisons, x86's integer-indefinite value for an
out-of-range or NaN conversion, and dump_wx_stats defined for the guest
architectures that do not compile it.
The libraries follow the gitlink, not the other way round:
scripts/ensure-ish-libs.sh fetches the release tagged libs-<sha> for
whatever HEAD the submodule is at, and treats a stamp that does not
match as no libraries at all. Both local build directories were carrying
e857383f's and have been replaced.
* fix(linux): the name dialog answers, and its field outlives its controller
Three things wrong with adding a second system, found by using it.
Tapping OK did nothing. `_askProfileName` awaited
`withTextFieldController`, which returns `void` — so `Future.sync` around
it completed before the dialog was answered and the name came back null,
which reads as "cancelled" and stopped the install. It owns its
controller now, because it needs the answer and that helper cannot give
one.
Then it turned the screen red. `showRoundDialog` completes when the route
is popped, but the field is still mounted and animating for a beat after
— the input decorator's own 167ms — so disposing the controller there
left a live `TextField` holding a dead one: "tried to build dirty widget
in the wrong build scope". Disposal is deferred past the transition,
which is what the delay inside `withTextFieldController` exists for.
Renaming had the same false await. It worked only because the work ran
inside the callback, which is exactly how the next person copies it.
Renaming to an empty name is ignored rather than stored: a row with no
title is worse than the name it had.
* build(ios): resolve the engine's libraries by tag, asked of the checkout
The fork now tags its releases `vX.Y.Z` rather than `libs-<sha>`, so the
download URL is no longer derivable from the gitlink alone. It is still
derivable from the submodule: the tag is on the commit, so
`git tag --points-at HEAD` answers offline, exactly, and without an API
call. What that preserves is the point of resolving through the gitlink
at all — the libraries and the source cannot drift apart, which "the
latest release" would have allowed silently.
`libs-<sha>` is tried when no version tag points here, so a gitlink
pinned before the change resolves the way it always did. A shallow
submodule, or one cloned before the tag existed, gets one `git fetch
--tags` first — not on every run, since the usual reason to be here is a
build directory that is empty or stale rather than a checkout that is
behind.
The gitlink stays where it is. The fork's commit is a CI change and
builds the same libraries; moving it would point this script at a
revision that has no release yet.
* chore(ish): bump the engine to 7e1fdded, the first versioned release
Nothing in the libraries changed — the commit is the publishing workflow
— but the gitlink is what scripts/ensure-ish-libs.sh resolves through,
and this is the first revision whose release is tagged v1.0.0 rather
than libs-<sha>. Both local build directories were fetched through the
new path to confirm it end to end.
* fix(file): an empty directory is marked, not narrated
It said "Empty" in a row of its own. The tab already has a way of showing
nothing — the icon on the surface beside the rail — and a directory with
no files in it is the same nothing seen from inside, so it says so the
same way.
The mark moves into `EmptyMark`, which `EmptyPane` now wraps. One
definition of how large it is and how faint, so the two cannot drift.
Kept as a row rather than filling the space: the `..` above it is how an
empty directory is left, and it has to stay reachable.
The failed search a few hundred lines down keeps its words. "Nothing
matched" and "this place is empty" are different things, and only one of
them is a state of the directory — the same icon there would send someone
looking for a wrong turn they did not take.
* fix(ci): satisfy the analyzer, and count the engine's exports rather than state them
Two red checks on #1329.
`flutter analyze` fails on anything it reports, `info` included, so six
directive-ordering notes and one unused import were enough. Sorted, and
the import removed.
The linkage check asserted eight `sbm_ish_*` exports. There are nine —
`sbm_ish_attach`, which entering one of several installed systems needs
— so a correct build failed. The count now comes from the header's own
`SBM_ISH_EXPORT` declarations, which makes adding one to the header the
whole of adding one.
Its failure message said "without `used`" inside a double-quoted string,
so bash ran `used` and printed "command not found" ahead of every
failure. Only reachable when the check fails, which is why it shipped.
* refactor(view): move the three page surfaces to fl_lib
None of them names anything of this app's: they are what a page looks
like with nothing on it, when it cannot get what it needed, and when it
is wider than one column deserves. Between four and seven callers each,
and nothing here that another app of ours would not want.
`PageColumns` was already half over there — `MultiList.kSpacing` names it
as the thing it shares its column arithmetic with, and both spelt that
constant out separately. Its test goes with it: a test for a widget that
does not live here any more does not either.
The imports go rather than move. Every one of these files already imports
fl_lib's barrel, which is where they come from now.
* fix(test): the symlink trap is a property of the link, not of the host
`an absolute guest symlink still counts` guarded itself by asserting
that `File('<root>/bin/sh').exists()` is false. That call follows links,
and the link points at `/bin/busybox` — a path inside the *guest*. So
the assertion was about the machine running the test: macOS has no
`/bin/busybox` and it passed, Ubuntu has one and it failed.
Both answers are wrong about the tree, which is the thing the test is
locking: absent means every existing install reads as uninstalled, and
present means it read a file in another tree entirely. `looksUnpacked`
does not follow links for exactly this reason.
So the guard states what it is really about — the target is
guest-absolute — and asks the host nothing.
* fix(linux): what a review found in the systems, and one thing above them
**A system let go of before its files do.** `sbm_ish_attach` is idempotent
by name, and nothing ever cleared the name. Deleting a system or
reinstalling one in place took the directory — including the database
behind the `/dev` mounted from it — while the engine went on believing it
was attached, so the next attach did nothing and a fresh tree was handed
the previous one's `/dev`: `attach_stdio` then failed to open
`/dev/pts/N`. Eight of those and `sbm_ish_attach` answers -EMFILE for
good. `sbm_ish_detach` unmounts innermost first and frees the slot, and
reports `EBUSY` rather than pulling a mount out from under a session.
**A scan that emptied the list it was rebuilding.** `scan()` cleared
`_profiles` and then awaited, but `profiles`, `selected` and `isReady`
are synchronous precisely because a widget being built reads them. Any
frame in that window saw nothing installed — no chips, no rail rows, and
`open` refusing for want of an id. Renaming one was enough. It is built
beside the list now and swapped in at the end.
**Deleting one closed terminals in another.** A tab that names no profile
was opened in whichever was selected, which is not necessarily the one
being deleted; closing those regardless took live terminals in a system
nobody had touched. Only tabs naming the deleted system close, and they
close whether the delete came from the terminal tab or the settings page
— `Rootfs.removed` is the one seam both go through, since only one of
those two holds the sessions.
**An empty id is not an absent one.** `_addRootfs` fell back to `''`,
which is non-null, so every `profileId ?? selected?.id` below it passed
the empty string on: the engine answers -EINVAL, and proot would have
been pointed at the container. It falls back to null and opens nothing
when there is nothing to open.
**A terminal that went silent for good.** `_drain` re-armed its one-shot
timer only on the path where the read returned. `IosRootfs.read` throws
when the engine answers -EBUSY — a guest thread died holding the output
lock, which is that read and not that session — and the throw left
`_poll` null: no more output, `done` never completing, the session never
removed. It re-arms either way.
**A comment that said the opposite of its code.** `prepare` still
explained that the directory keeps its old name because renaming it would
orphan every install, directly above the line that renames it. What it
does is now what it says, with a TODO for the tree left behind.
* fix(ios): the Live Activity says what is open, not that it is SSH
Two shells inside the Linux userland on this device were reported as
"Multiple SSH sessions active", because that string was a constant in
`LiveActivityManager` applied to whatever happened to be open. The
title said "%d connections", which is wrong for the same reason: a
local shell is not connected to anything.
The title is "%d terminals" now, and the subtitle is the sessions' own
names, sent from Dart and shown as they are. Names cannot be wrong about
what the sessions are, and they say more than a sentence that only
counts them. The widget holds them to one line. Dart's copy of the old
English string went with it — the Swift side overrode it, so it had
never been displayed.
The two targets' Localizable.strings were copies of each other, and both
are needed: `NSLocalizedString` resolves against the bundle of the
process that calls it, and the widget extension is a separate process
that cannot see the app's table. What they hold should differ, though,
and it does not overlap at all — the app formats the title, the widget
localizes the statuses. Each now carries only the keys its own target
resolves.
`Text("Loading")` in the widget is a SwiftUI literal and so a
`LocalizedStringKey`. There was no `Loading` key anywhere, so it fell
back to English in every language, silently. Added.
* chore(ish): bump the engine to 65827ef4, with everything but the engine gone
The fork dropped the iSH app, the x86 guest, the Linux kernel mode and
unicorn — about 46k lines of what this repository builds none of. What
is left is what ServerBox links: the arm64 guest, fakefs, and the shim
around them.
The libraries came through the version tag rather than the legacy
`libs-<sha>` fallback, which is the first time that path has resolved
for real: `v1.0.4`, fetched for both targets and verified against
SHA256SUMS. A release build still links the engine —
`check-ish-linkage.sh ... on` passes with 6 internals, 89 strings and
sqlite present.
That check also reports ten exports now rather than nine, and did not
have to be told: `sbm_ish_detach` arrived and the count comes from the
header. `off` is left to CI, which builds the engine from source on this
path and is the only place the local build script gets exercised.
* fix(monitor): the rest of what the review found, outside the Linux systems
**A command that filled a pipe stalled the whole cycle and was then
thrown away.** The readers stop at the cap and leave the pipe undrained,
so a child that keeps writing blocks on a full pipe and never exits:
`child.wait()` ran to the 30 s timeout and the segment was discarded as a
timeout rather than reported as too much output. The "produced more than
N bytes" error was only reachable when the child happened to stop by
itself, which is what the test does. Whichever pipe fills first now says
so and the child is ended there — a wide smartctl sweep or `nvidia-smi
-q -x` on a many-GPU host costs a signal instead of half a minute.
**A shipped migration cannot be edited, and nothing said so.**
`Migrator::run` compares the checksum in the binary against the one
`_sqlx_migrations` recorded, so touching a file that has already run —
even a comment — makes those agents refuse to start with
`VersionMismatch`, which an operator cannot fix from outside.
`migrations_apply_to_a_database_that_already_has_rows` cannot catch it:
it starts from an empty database and replays the current files, so the
checksum it records is always the new one. The checksums are pinned
instead. Nothing is restored: 006 was last edited on main and monitor has
never had a release, so no agent in the field ever recorded the old one,
and flipping the bytes back would only move who is broken.
**A panic macro on a value that arrives in a request body.** The purpose
was compared against the enum's only variant and the mismatch declared
`unreachable!()`. Dead today, and a POST that panics the worker the day a
second variant is added. It is read and dropped; everything below names
the variant outright.
**A parser on a security boundary lost its tests.** `query_param` was
copied out of the deleted tunnel endpoint and its tests were not. They
pin what a hand-rolled query parser gets wrong — `myticket=abc` matching
`ticket`, a bare key counting as a value — and without them switching
`==` to `ends_with` passes every other test in the file.
**Two lifetimes shared one flag.** `dispose` set `_clearing` to mean
"finished, start nothing", and `_clear`'s `finally` put it back. Disposing
during the clear that `delServer` awaits therefore left the guard open,
and a later `startForward` ran on a disposed notifier. `_disposed` is set
once and never unset.
**A digest check that was not one.** The engine archive was verified
against a SHA256SUMS from the same release, described as the standard
`IosRootfs.install` holds the rootfs to — but that one compares against a
constant in the source, so a replaced release fails it, while this one
brings its own sums and passes. The comment now says what the check does
and what actually stands behind it, with a TODO to pin the digest beside
the gitlink. Extraction drops the archive's owner.
* chore(ish): bump the engine to a34c1d2e, eleven fixes and an upstream merge
Brings in the applicable half of upstream's sixteen commits plus the
fork's own: `O_NOFOLLOW` honoured in `path_normalize` rather than at the
host open, `waitid`'s `si_status`/`si_code`/`si_uid`, `waitpid`'s internal
timeout treated as a retry instead of a signal, ASIMD FCVTN/FCVTL/FCVTXN
lane conversions, and regression tests for the fs and wait fixes.
`O_NOFOLLOW` lands in the same function as the task-root handling this app
needs, so both were checked afterwards rather than assumed: `root_floor`
and the root-aware cache are still in `fs/path.c`, and `getcwd` still
strips only a root longer than "/". Both engines build, and
`ios/Runner/ish/sbm_ish.c` still compiles against the new headers.
Not verified on a device. The last run there was on the previous
revision.
* fix(ui): an empty server tab shows the mark the other tabs show
It said "Empty" — a word for a list that could have held something, on
the one page a new install opens to, where what to do is the button
floating over it. The terminal, file and snippet tabs answer the same
state with a faint icon and no words, on the reasoning that a sentence
would be telling the reader what they are already looking at.
Two call sites because they are one surface at two widths: with nothing
selected there is no detail pane, so `AdaptivePanes` hands the list the
whole window, and what a wide window shows when the tab is empty is that
list rather than a rail beside something.
The fullscreen status mode in landscape.dart still says "Empty". It is a
display of its own with its own conventions and is left alone.
* style: sort rootfs.dart's imports, which the analyzer fails CI over
* chore(ish): bump the engine to 3cb7c7f2, integration tests and a uname fix
An end-to-end suite for the guest, on Ubuntu 26.04, keeping stderr when a
case fails — and the first bug it found: a host name longer than the field
`uname` copies it into killed the process.
The task-root handling this app depends on is still there — `root_floor`,
the root in the cache key, and `getcwd` stripping only a root longer than
"/" — and both engines build with `ios/Runner/ish/sbm_ish.c` against them.
Not verified on a device at this revision.
* fix(snippet): add sits in the bar, where the rest of the app keeps it
It floated over the list, which cost it two of itself — a small one for a
pane and a full-size one for a single column — and covered the last row
of the thing it adds to. Beside search in the bar it is one button, at
one size, and the page reads like every other list in the app.
The two tests that pinned the old placement now pin the new one: both
actions reachable at either width, and no floating button at all.
* fix(file): the plus in a file browser adds a file, not a server
It opened the server form. That was deliberate once — a server this app
does not know cannot be browsed — but it left the tab with the wrong
plus and no right one: new folder, new file and bringing one in from
outside were reachable only by right-click, which a phone does not have.
On mobile there was no way to add a file at all, and the only visible
plus belonged to the server list.
The browser's own create menu moves into its top actions, so the button
opens the same three the secondary tap always gave. The tab stops
offering to add a server: that is the server tab's, and this tab lists
what already exists.
Not offered while picking a file or a directory. Those are there to
choose something that exists, not to make something new.
* rm(ssh): the two ways this tab offered to add a server
It had both a plus in the bar and a floating one, and each went to the
server form — while the other thing this tab opens a terminal on, a Linux
system on this device, had neither. Adding a server belongs to the server
tab; adding a system belongs to the chip that lists them. This tab lists
what can be opened.
Editing a server is still a long press on its card, and the rail keeps
its own.
* fix(ish): a session killed by a signal said it succeeded
`code` is the raw wait(2) status word. Only a normal exit puts the code in
the high byte: `kernel/exit.c` calls `do_exit_group(sig)` for a death by
signal, which leaves the signal in the low 7 bits and nothing above them. So
`code >> 8` answered 0 for every one of them, and 0 is what
`ExecResult.exitCode` means by success.
Report 128 + signal, as a shell does, so a caller that knows what 143 means
needs no telling. It also stays positive, which the field requires:
`sbm_ish_exit_code` uses a negative value for "still running".
Restore the stub branch, which has not compiled since 5f9301fd put a second
copy of `sbm_ish_detach` in it — the real one, referencing `booted` and
`do_umount`, neither of which exists with the engine off. That is the default
(`SBM_ISH = 0`); only a checkout carrying the untracked IshLocal.xcconfig was
building the branch that works.
Set `uname_hostname_override`. Without it the guest's hostname is the host's
nodename, which on iOS is the device name: something the user typed, usually
carrying their own, and reaching the guest's prompt and whatever it writes
out. It is also not a hostname — the field is 65 bytes and `do_uname`
truncates to fit, so a multi-byte name is cut mid-codepoint.
Drop two settings that do nothing: ENGINE_ASBESTOS has had no reader since
unicorn was removed, and `ish.p` is meson's private directory for the `ish`
executable, which a cross build does not produce.
* fix(monitor): pin migration bytes to LF, and collapse the overflow guard
`shipped_migrations_keep_their_checksums` failed on windows-latest and
nowhere else. sqlx hashes each migration file's bytes, `migrate!` embeds them
at compile time, and the Windows runner checks out CRLF — migration 1 hashes
to 1ca2d91b… there against ac7a765b… everywhere else. Reproduced locally:
piping the file through `s/\n/\r\n/` gives the runner's value exactly.
The test is the thing that noticed, but the consequence is not confined to
CI. Those checksums go into the agent's `_sqlx_migrations`, so a build from a
CRLF checkout disagrees with whatever an earlier build recorded and the
migrator refuses to start. `.gitattributes` fixes the bytes at LF.
Also collapse the nested `if let` in the overflow announcement, which clippy
rejects under `-D warnings`. The crate is edition 2024 and
`terminate_process_group` a few lines down already uses a let-chain.
Still failing and not explained: `an_external_command_cannot_silently_
truncate_output` on windows-latest, which 718b03a3 introduced and which
passes on macOS and did pass on Windows before that commit.
* test(monitor): ask windows-latest what the child actually wrote
`an_external_command_cannot_silently_truncate_output` times out there and
passes on Linux and macOS, and the failure it reported — `unwrap_err()` on an
`Ok` value: None — is the timeout branch, which cannot say whether the child
produced the bytes at all. Read statically the path looks the same on both:
PowerShell writes MAX+1, the reader's `take` cap is reached, the overflow is
announced. Something in that chain is not happening and guessing at which
link would be guessing.
So: report what the call returned instead of `unwrap_err`, which is worth
keeping either way, and run the same PowerShell command plainly first. cargo
prints a failing test's output, so the probe is only read on the run that
needs it.
The probe goes once the answer is in.
* fix: what the review found, verified against the code first
Each of these was checked against the current file rather than taken from the
report; the ones left undone are listed at the end.
Reachable from outside:
- `sbm_ish_attach`/`_detach` refused a profile containing `/` but took `..`,
which every path here builds as `/<profile>/...` and normalizes straight
back to the machine root. One `check_profile` for both.
- `make_dev` returned void and gave up silently when its database failed, and
`sbm_ish_attach` recorded the profile anyway. Attaching is idempotent by
name, so that is a half-built system nothing ever retries: every later
attach sees the name and returns 0, and the session opens onto a `/dev`
that was never mounted.
- `LiveActivityManager.start` is on an actor, which is not a lock across a
suspension. A second call arriving while `request` awaited found no
activity to update and asked for another — two Live Activities for one
terminal, only the later one reachable. Single-flight through a `Task`.
- `IosRootfs.install` picks its id from the scan that opens it, so two
overlapping calls were handed the same id and the same directory.
- `seedChsh` read `usr/local/bin/chsh` with `readAsString`. The comment two
lines down anticipates `apk add shadow` putting a compiled binary there —
decoding one throws, out of a function that runs while the app starts,
before the check that would have said to leave it alone. Bounded prefix,
decoded loosely, empty on failure, which reads as somebody else's file.
- `IshExec`'s console decoder was strict, so a session hung up mid-character
answered `close()` with a `FormatException` instead of returning output.
- `stopForward` wrote to a disposed notifier: `close()` is awaited and
`dispose` can run underneath it. Every other path there already checks.
- `removeProfile` and `AndroidRootfs.enter` built paths from an unvalidated
id. `rootOf` only joins, so anything a caller passes becomes a path — one
of them a recursive delete.
- `AndroidRootfs.prepare` returned before `scan()` when the native library
directory was missing, leaving every installed system invisible. Whether
proot is present decides what can run, not what is installed.
- `chmodGuestFile` looked `chmod` up as taking a `uint16_t`, which is
`mode_t` on Darwin only. `ios_rootfs.dart`'s private copy is gone.
- A profile label reached the marker unescaped, and a newline in one writes a
fourth line that `decode` reads as a truncated name.
- Poll rearms at the idle interval after a read error rather than 60 times a
second at the busy one.
Tests that were not testing what they say:
- `chsh_script_test` rewrote the conf path into the temp tree but left
`/etc/shells` absolute, so `-l` read the host's while the test wrote a
fixture nothing opened — and then asserted only the exit code. Both paths
are redirected now and the output is compared.
- Four integration tests called `install` unconditionally, which adds a
system rather than reusing one, or removed a single profile using a
distribution id where a generated profile id belongs.
- `shipped_migrations_keep_their_checksums` asserted over the pinned list, so
a migration added tomorrow would be pinned by nothing.
Scripts:
- `ensure-ish-libs.sh` unpacked a replacement over the previous revision's
libraries. `have_libs` only asks whether the three are present, so one the
archive did not carry survived and linked into a build it was not built
for.
- `version_tag` piped into `head -1` under `pipefail`.
- `check-ish-linkage.sh` reached for the single-quote escape idiom inside a
double-quoted string, where a single quote is already literal.
Left undone, deliberately:
- Reinstalling deletes the tree before downloading its replacement, so a
download that fails takes the user's system with it. Real, and reachable
through the update row on Android. The fix is to stage and swap, which
reshapes the whole install path and wants device verification.
- The pre-container `alpine/` tree: still a TODO, still nothing has shipped
that needs migrating.
- Hardcoded `'Linux'` in the terminal tab. `'DNS'` in the same feature is
hardcoded for the same reason, and there is no such l10n key.
- `Rootfs.rename` returning a result, and the Kotlin block in
`android/build.gradle`: shape, not behaviour.
* test(monitor): stop the overflow test measuring the runner's process startup
The probe answered what it was for. On an idle Windows box the child starts,
writes its megabyte and exits in 179 ms, status 0, nothing on stderr — so the
command was never the problem, and neither was a cold PowerShell.
It also did not reproduce. 70 runs on real Windows hardware, twelve of them
concurrent, never failed; windows-latest failed three of five. The runner is
roughly ten times slower and shared, and a five-second budget for a 179 ms
operation is the kind of margin that holds until it does not.
Which also means the earlier attribution does not survive its own evidence.
Two passes before 718b03a3 and three failures in five after is not a sample
that separates "introduced a race" from "a flake that had not landed yet",
and I stated it more firmly than that.
So: raise the budget to 30 seconds, because how long a machine takes to move
four megabytes is not what this asserts. Detection that is genuinely broken
still fails, only later.
And write comfortably over the cap rather than one byte over it. At exactly
`MAX + 1` the reader reaches its `take` limit in the same moment the child
finishes and exits, so the overflow and the wait become ready together and the
test stops being about either. Well over, the reader hits the cap while the
child is still writing and then blocks on a full pipe — the case the
announcement was added for.
Not verified against the failure: it never reproduced here, so what this
removes is the sensitivity, not a mechanism anyone has seen.
* fix: three things the last round left, two of them mine
`sbm_ish_attach` mounted `/proc` and then returned when `make_dev` failed,
without taking it back. `do_mount` does not ask whether the point already
carries a mount, so the next attempt stacked a second procfs on the same path
— one per failed attach, and only the innermost reachable to unmount. That
one arrived with the make_dev error propagation in 8d2ba9e2.
`sbm_ish_detach` unmounted outside `attached_lock` and took it only to clear
the slot. `sbm_ish_attach` holds it across its own mounts and answers 0 for
any name it finds in the table, so an attach running alongside a detach read
the name as still attached, returned without mounting anything, and handed
back a system whose filesystems were being pulled out underneath it. The
whole unmount-and-clear is under the lock now. On the failure path the name
stays in the table, which is correct: its mounts are still there. No nesting
to deadlock on — `is_attached` does not lock, and nothing reached from either
function takes this mutex.
`LiveActivityManager` had two, and the single-flight in 8d2ba9e2 only closed
the first half. A second `start` waited for the request in flight and then
took *its* result, so the newer payload was dropped; it applies its own
content to the activity that comes back instead. And a `stop` arriving while
a request was in flight could not end an activity that did not exist yet, so
the request finished afterwards and put it in `current` — a Live Activity
appearing for a terminal the user had just closed. A generation counter, and
the request ends what it built rather than recording it.
Not done: tests for those two. There is no XCTest target in the project, and
adding one is `project.pbxproj` surgery I cannot build to verify from here.
Verified: both branches of sbm_ish.c under `clang -fsyntax-only`, and the
Swift file type-checks against the iOS SDK down to `TerminalAttributes`, which
lives in the widget extension and is out of scope for a single file.
* fix(ish): the exemption for an unmounted point never applied
Found while checking the review's two mount findings, and larger than either.
`kernel/errno.h` defines its constants already negative — `_ENOENT` is -2 —
and `sbm_ish_detach` tested `one != -_ENOENT`, which is `+2`, a value no error
equals. So the "not mounted is not a failure" exemption was dead code.
`do_umount` also answers `_EINVAL` rather than `_ENOENT` for a point that
carries nothing, so it would not have applied even negated correctly. Every
detach of a profile whose four mounts were not all present reported failure —
including one that had never been attached at all, which is what
`removeProfile` does when no terminal opened the system this run.
The two findings and that bug are one shape, so one helper:
- `unmount_profile` takes a profile's filesystems down, exempting `_EINVAL`
and keeping `_EBUSY`, which are `do_umount`'s only two errors.
- `sbm_ish_attach` calls it before mounting anything. Whatever is there is

…he schema (lollipopkit#1322) * feat(store): the entity schema, with the rules in it Sixteen tables for the seven entities, replacing JSON blobs in `kv`. Two conventions the old layout could not express: A primary key is an id, never something the user typed. Snippets were keyed by name and private keys by a name-used-as-id, so renaming either broke every reference — `Spi.ssh.keyId` pointed at a private key's *name*. Names are ordinary `UNIQUE` columns now and a rename is one `UPDATE`. A list or map field is a child table. `server_tag`, `server_env`, `server_jump`, `server_disabled_cmd`, `server_custom_cmd`, `snippet_tag`, `snippet_auto_run_on`, and `known_host` — which was a JSON map in `setting` keyed `<serverId>::<keyType>`, so a deleted server left its fingerprints behind for ever. Rules that lived in one call site now live in the schema. SSH-or-monitor exclusivity was `Spix.validate()` alone, so a record could be written with both and fail later at connect time; it is a CHECK. Orphan cleanup was six hand-written calls in `delServer` that missed four more (agent conversations, port forwards, container hosts, known hosts); it is ON DELETE CASCADE. Deleting a private key sets its servers' key to null rather than deleting them. `setting` and `history` stay in `kv`: 103 unrelated preferences with no relations and nothing that queries by field, where a new one should stay a one-line change rather than a migration. `agent_conversation.data` stays JSON — an ordered log of heterogeneous items, only ever read whole. Columns would buy nothing and cost a migration per new item kind. Nothing writes to these yet; the stores and the m004 migration come next. * feat(store): carry the metadata an incremental sync needs Sync uploads the whole backup every time, so the cost grows with the data rather than with the change. Fixing that needs per-row change tracking, and adding it after the m004 migration has run would be a second migration — so the columns go in before anything writes to these tables. `updated_at` is what an incremental pull selects on; `rev` separates two edits inside one millisecond, which a clock cannot. Both live on the six sync roots only. A server and its tags, envs and jump hosts are one logical record: the children cascade with the parent and have no meaning without it, so syncing them separately would let a tag arrive before its server. `tombstone` makes a deletion a fact that can travel. Without one the peer that still holds the row reads its absence as an addition and puts it back, which is how a deleted server returns on the next sync. `sync_state` holds this device's id and its per-peer watermarks, and is never itself uploaded. The remote is a whole-file interface — `upload`/`download`/`list`, no range requests, no ETag — so the protocol on top of this has to be an immutable base plus append-only change files, named per device and sequence, with the peers pulling only what they have not seen. That comes next; this is what it will read. * feat(store): m004, entities out of kv and into tables One transaction: a migration that stops half way leaves the records in two shapes with nothing to say which is authoritative. Snippets and private keys get real ids. Both were keyed by a name the user typed — a private key's `id` *was* its name — so `Spi.ssh.keyId` pointed at a name and renaming a key detached every server using it. The old ids are mapped to generated ones and the references rewritten as they are copied. Rows that point at nothing are dropped rather than carried: `conn_stat` has a foreign key now, and the hand-written cleanup in `delServer` missed cases, so an upgrading install holds statistics for servers deleted long ago. Same for a jump host, a port forward or an auto-run target naming a server that no longer exists. Each is logged. A server that could be reached neither way, or both, cannot be represented under the new CHECK. It could not be connected to before either — `genClient` had nothing to dial — so it is dropped with a warning rather than failing the migration for every other record. `updated_at` is carried across instead of stamped as now, so the first sync after upgrading does not read as "everything changed today". `conn_stat`, `agent_conversation` and `agent_active` already exist under those names and `createAll` is `IF NOT EXISTS`, so they are renamed aside, recreated and copied through. Also fixes the ordering this exposed. `HiveImport` recorded `current`, which after adding v5 meant an upgrading install was marked done while its records sat in the v4 kv shape — `migrate` would have skipped m004 and stranded them. It now records `hiveImportProduces`, the layout it actually writes, and the two tests that asserted otherwise say so. * test(store): cover every released build as a migration source The SQLite layout has not shipped, so every install in the field is on Hive and 1466, 1480 and 1491 are all upgrade sources. The suite ran against one. `hive_adapters.g.dart` is byte-identical across the three, so they share one set of assertions — but that is a fact worth checking rather than assuming, so 1480 gets a fixture generated from its own tag even though the generator ran against it unchanged. 1491 shipped an `agent_conversation` box the others do not have, which is the case that needed its own data. The test is now parameterised over the three. `Paths.doc` is `late final` and cannot be set per group, so one temp directory is refilled from the fixture under test in `setUp`. Building the 1491 conversations by hand first is what caught the reason these fixtures exist: written as JSON with camelCase keys and a `type` discriminator they were silently dropped on import, because the release writes snake_case and `kind`. They are built through 1491's own model and serialiser now, and the README says why. * feat(store): the base an entity store sits on Deliberately not a `KvStore`: there is no key-addressed `get`/`set` here, because the records have columns, relations and constraints now. What it keeps is the shape the app already talks to — `fetch`, `fetchOneRaw`, `put`, `delete`, `watch` — so the call sites go on passing models around without learning which storage backs them, and this change stays in the storage layer instead of spreading through the app. `deleteById` is one statement: every child table declares ON DELETE CASCADE, replacing the six hand-written cleanups in `delServer` and the four it missed. It writes a tombstone as it goes, because a peer that still holds the row reads its absence as an addition and puts it back. `put` stamps `updated_at` and increments `rev` in the same transaction as the write, and `touch` does it for a parent whose child rows changed — an edit to a tag is a change to the server that owns it. Both clear any tombstone for the id: a record that comes back has stopped being deleted. * feat(store): ServerStore over the server tables A Spi is six tables now, read with six statements total rather than six per server: each child table is read once and grouped in Dart. `upsert` exists because the test caught `INSERT OR REPLACE` resetting `rev` to its default on every write — that statement deletes the row and inserts a new one, so every column absent from it goes back to the default, and `rev` is the one column that must not. It is an `ON CONFLICT DO UPDATE` naming only the data columns, leaving `updated_at` and `rev` to `_stamp`. Child rows are replaced wholesale rather than diffed: the record arrives as one object, so what it no longer carries is what was removed. A jump host that no longer exists is dropped instead of written as a dangling reference, which the old JSON array could hold and this cannot. Tags come back as a set rather than in the order the JSON array kept: the child table has no ordering column and the UI filters by membership. Noted in the test rather than left to be discovered. `idsWithTag` and `allTags` are what the server list used to get by decoding every record. * build: add drift, on the connection the app already opens The storage layer is hand-written SQL strings and hand-written row mapping, which is what an ORM generates. `INSERT OR REPLACE` silently resetting `rev` — caught by a test, not by the compiler — is the kind of thing typed queries prevent. Verified before committing to it, because encryption is the constraint that would have ruled it out: `NativeDatabase.opened` takes the `sqlite3` `Database` this app opens and keys itself, so sqlite3mc and the build-hook bundling are untouched. A spike confirmed the SSH-xor-monitor CHECK still fires and a dangling foreign key is still refused through Drift's executor — `foreign_keys` is per-connection, so that also confirms Drift is on the same connection rather than opening its own. drift_dev is pinned to 2.34.0 rather than 2.34.5: `hive_ce_generator` wants analyzer ^12 and 2.34.1+ wants ^13. That generator only exists to rebuild the frozen Hive adapters `HiveImport` reads, so it goes when that does. * feat(store): Drift owns the schema The 18 tables are Drift table definitions now, and `tables_schema_test.dart` was the acceptance gate: all 17 guarantees pass against what Drift creates — the SSH-xor-monitor CHECK, the cascades, ON DELETE SET NULL for a deleted private key, the unique names, the sync columns, the tag queries. With that shown, the hand-written DDL is a second source for one schema and is gone; `Tables` keeps only the name lists. `schemaVersion` is 1 and stays there. Version stays with `SchemaVersion`, because the steps that matter are outside what a Drift migration can express: m003 reads Hive boxes, m004 remaps ids and rewrites the references between them. Two mechanisms advancing one number is the ambiguity this change exists to remove. Drift cannot reference a column inside its own `check()`, which the analyzer caught as a recursive getter three times; those are table constraints instead. m003 no longer writes through the store objects. It produces the v4 key-value shape and those stores have moved on to tables — a migration that calls today's code changes meaning every time that code does. It writes into `kv` directly, with `updated_at` 0 so m004 can carry the real timestamps forward and the first sync after upgrading does not read as "everything changed". drift_dev is 2.34.0: `hive_ce_generator` wants analyzer ^12 and 2.34.1+ wants ^13. That generator goes when `HiveImport` does. The tree does not compile past the store layer yet — the six remaining stores and their call sites are the next step. * feat(store): the entity stores over their own tables Every store that holds records now reads and writes columns rather than a JSON blob in `kv`: private keys, snippets, port forwards and the container settings join the servers that moved first. Three things that were data loss, found while porting: - A private key's id *was* its name, and a snippet's key was its name. Both are generated ids with the name as an ordinary unique column now, so a rename is an UPDATE rather than a delete and an insert that leaves every reference behind. - m004 mapped `ssh.keyId` through the old-id table and wrote null when it matched nothing — which is exactly what an `IdentityFile` path put there by the ssh-config import looks like. It lands in `ssh_key_path` now, which is what `ServerStore.migrateIdentityFilePaths` used to recover it into. - The `docker` store's bare `<serverId>` keys, the Docker host from before per-runtime hosts, were dropped along with `providerConfig`. Both are carried across. `migrateIds` and `migrateIdentityFilePaths` are gone from the launch path. They scanned every server on every launch to repair a shape only an upgrading install can hold, and neither could have run after m004 anyway: an empty `Spi.id` has nowhere to live once the id is a primary key. m003 now writes one shape — rows in `kv` — instead of three. It no longer reaches through today's store objects for connection stats and agent conversations, so m004 owns every table and the rename-aside dance goes with it. The schema is created when the database is opened, which is what lets m004 stay one synchronous transaction. Also: container hosts and the chosen runtime are children of `server` rather than records of their own, so they cascade and travel with it; port forwards are in the backup for the first time; `conn_stat` rows get generated ids, so two attempts in the same millisecond no longer collide. The tests do not compile yet. * test(store): the whole upgrade path, and the adapters it broke `hive_release_migration_test` now runs HiveImport *and* KvToTablesMigration against each release fixture, so what it asserts is the shape the app reads rather than an intermediate no build ships. 42 assertions across 1466/1480/ 1491; it found five real bugs on the first run: - The generated Hive adapters no longer read any released box. Adding `id` to `Snippet` and `name` to `PrivateKeyInfo` made the generator emit `fields[n] as String` for a field those bytes do not carry, so both boxes failed to open and every snippet and key was silently left behind. They are frozen types in `lib/hive/legacy_adapters.dart` now, like `LegacySpiV2` already was, and out of `@GenerateAdapters`. - m004 read `ssh['keyId']`, but `SshCredential.toJson` writes `pubKeyId` — kept from the flat pre-v3 layout. Every server lost its key. - It read `key['key']`, but the released `PrivateKeyInfo.toJson` writes `private_key`. Every key was dropped. - It read `conversation['serverId']`, but `AgentConversation.toJson` is hand-written and snake_case. Every conversation was dropped. - `_toSpi` built a `ServerCustom` unconditionally, since the columns are NOT NULL with defaults, giving every server a non-null `custom` it never had. `hive_import_test` keeps its own scope — retry, idempotency, per-box progress — and asserts against `kv`, which is all the import produces now. It seeds through the released layouts rather than today's models. Two behaviour changes the tests pin down: deleting an agent conversation now cascades to the active row, so which one was active is read before the delete; and two connection attempts in the same millisecond are two rows, which is what generated ids were for. 1036/1036 tests pass. * feat(store): the call sites, and a unique name the user is told about A rename is an UPDATE of one column now, so the providers stop deleting and reinserting: that wrote a tombstone for a record that is still there and took its tags and auto-run targets with it by cascade. Renaming a snippet tag is one statement over `snippet_tag` rather than rewriting every snippet holding it, and the second copy of that loop in the provider is gone. Names are unique in the schema rather than in whichever dialog last checked, so a collision surfaces as `DuplicateNameException` and both editors turn it into a message and stay open on the field the user has to change. One new string, `nameAlreadyExistsFmt`, in en and zh. * docs: the storage layout as it is, not as Hive was `docs/development/architecture.md` still described hive_ce in both locales. Replaced with what is there: one encrypted SQLite file, two shapes in it and the rule for choosing between them, Drift owning the DDL and nothing else, ids that are not names, children that travel with their parent, and the two migration steps. CLAUDE.md gets the parts that steer future work — `INSERT OR REPLACE` being wrong on any row with sync columns or children, and that changing a model `lib/hive/` still has a generated adapter for makes every box written before it unreadable. * build(fl_lib): follow the KvStore rename onto current main The submodule pointer was a local commit based on fl_lib before lollipopkit#40, which made `clear` asynchronous and `SyncIface` non-const. Rebasing onto main brings both: - `BakSyncer` stops being a const singleton, since `SyncIface` no longer has a const constructor. - Three `store.clear()` calls did not await, so the settings page reported success before anything was cleared and two tests asserted on a store that had not been cleared yet. - `CachedSqliteStore` is deleted. Every store that extended it — server, private key, snippet — owns a table now, so it had no subclasses left. Blocked on lollipopkit/fl_lib#42; CI here cannot resolve the submodule until that lands. * fix(store): review follow-ups on lollipopkit#1322 Restore ordering, two silent losses, and a generated id shown to the user. - **A jump host is a server**, so during a restore the row it names may be written later. `write` inserted the link inline and dropped any forward reference; `writeLinks` is a second pass `replaceAll` and `merge` run once every row exists. - **The key picker rendered `item.id`.** With ids generated, that chip showed the user a `ShortId` instead of the name they typed. - **`_toEncodable` did not know `PortForwardConfig`**, so a backup carrying a typed one threw. Covered by a round trip through `fromJsonString`. - **`merge` stamped `updated_at = 0`** for a record the backup carried no timestamp for, leaving it older than anything — the next sync would take it straight back out. Absent means now. - **m004 collapsed duplicate snippet names.** Two snippets sharing a stored name produced two records but one `renamed` entry, so both `snippetOrder` entries resolved to whichever was de-duplicated last. - `SnippetNotifier.update` refuses a changed id, which `EntityStore.update` already did and going straight to `put` bypassed. - Deleting an agent conversation and promoting its replacement are one transaction: the delete cascades the active row away. - `resetTables()` for a caller that closes the handle itself, and the previous `AppDb.close` is best-effort. - The private key editor only touches `_loading` while mounted — `decryptPem` runs on another isolate. - Docs, the fixture README's destination path, an assertion no byte could satisfy, two unused temp dirs, and a key fixture whose id and name differ. Not taken: fl_lib's `set`/`setAll`/`remove` are synchronous — only `clear` returns a Future, and both call sites await it. `Stores.x` already resolves through GetIt. 1041/1041 passing. * fix(store): second review round, and the new string in every language l10n: `nameAlreadyExistsFmt` was only in en and zh. All 15 locales now, with each one's own quotation marks rather than a copy of the English. - **`merge` dropped every record from a backup that carries no timestamps.** It compared timestamps before asking whether the record exists here, so an addition read as `0 <= 0` — a tie — and was skipped. Every older envelope is like that. A record this device has never seen is an addition; only one the backup knew about and no longer holds is a delete. - **m004 left agent conversations pointing at a pre-migration server id.** A server whose id was regenerated took its conversations' scope with it now, while a scope that names no server — the global agent's — is kept as it is. - m004's `INSERT OR REPLACE` on `agent_conversation` would delete the active row by cascade; `ON CONFLICT DO UPDATE` instead. - `PrivateKeyNotifier.update` refuses a changed id, like the snippet one. - The private key editor's catch no longer clears `_loading` unguarded — the `finally` does it, and only while mounted. Three tests for the restore fixes: a jump host named before it arrives, a backup with no timestamps, and a record the backup never knew about. Not taken, all pre-existing on main and untouched here: the auto-refresh timer dropped without cancelling, two unawaited `connectionStats` clears, and `SandboxImport.run()` ordering — all from lollipopkit#1318. Reverted my own edit to `sshHostKeyFingerprintMd5Hex`: the key has no call site anywhere in `lib`, so whether it should say MD5 or SHA256 is not something this diff can answer. 1044/1044 passing. * fix(store): a migrated conversation kept the old server id in its payload m004 remapped `agent_conversation.server_id` when a server's id was regenerated, but re-encoded the original JSON beside it. The store rebuilds a conversation from `data` and then compares `conversation.serverId` against the server it was asked about — `fetchActive`, `setActive` and `deleteConversation` all do — so the column found the record and every one of those three rejected it. The conversation existed and nothing could reach it. `test/m004_id_remap_test.dart` covers the rule the bug broke: a server stored before 1155 has an empty id and lives under `user@ip:port`, so the migration generates one, and everything naming the old key has to follow in the same pass. Six cases — the id itself, agent conversations in both places, snippet auto-run targets, port forwards, container hosts and `serverOrder`. Checked against a reverted fix: the conversation case fails without it. 1050/1050 passing. * test(store): pin the hand-written m004 seed to what a release wrote The seed in `m004_id_remap_test` was a claim from memory about what `HiveImport` leaves for a pre-1155 server. Four such claims in this branch turned out wrong, each silently dropping a whole store, so it should not be one. Not by feeding that test release bytes: m004 does not consume any. Its input is what m003 leaves in `kv`, which is this repo's own intermediate — release bytes are m003's input, and `hive_release_migration_test` already runs all three fixtures through both steps. Instead the one fact the seed rests on is asserted there, against 1466/1480/1491: a server from before 1155 reaches `kv` with `id == ''` and an `ssh` map, and it is the only record that does. The seed cannot drift from a real upgrade without that failing. Verified by probe before writing it, rather than assumed again. 1053/1053 passing. * docs(test): say only what the fixture assertion covers The header claimed the `kv` key was "the form such an install used" and that the seed was "written the way 1466 wrote it". The release-backed assertion covers two things and neither is the key: `id == ''` and `ssh` nested under one key. So the comments now name those two, and say plainly that the key is an arbitrary legacy reference whose shape nothing asserts and nothing depends on. A comment claiming fixture backing it does not have is worse than none — it is the kind of thing a later reader trusts instead of checking.

Moves every record with relations out of a JSON blob in
kvand into tableswith columns, foreign keys,
CHECKconstraints and indexes.PRAGMA foreign_keys = ONwas already set and was a no-op: there were zeroREFERENCESin the codebase, because servers lived as JSON.Depends on lollipopkit/fl_lib#42 and #43, both merged; the submodule points at
fl_lib main.
What moves, and what does not
settingandhistorystay rows inkv— a hundred unrelated preferenceswith nothing that queries by field, where adding one should stay a one-line
change. Everything else owns a table:
server,private_key,snippet,port_forward,conn_stat,agent_conversation, plus the child tableshanging off them.
Drift owns the DDL and only the DDL (
lib/data/store/db.dart). Queries stayhand-written and synchronous, because the UI reads a store while building —
converting ~100 call sites to
awaitwould have been the change, not theschema. Drift never opens the connection either:
SqliteDbdoes, applies thesqlite3mc cipher and the
foreign_keyspragma, and hands the live handle over.AppDb.schemaVersionis pinned at 1 forever; version staysSchemaVersion,because the steps that matter read Hive boxes and remap ids.
Two conventions the old layout could not hold
A primary key is an id, never something the user typed. A private key's
idwas its name, so renaming one silently detached every server pointing atit —
Spi.ssh.keyIdheld a name. Snippets were keyed by name the same way.Both have generated ids and a
UNIQUEname column now, so a rename is anUPDATEof one column, and a collision surfaces asDuplicateNameExceptionwhere the schema finds it rather than in whichever dialog last remembered to
check.
A list or map field is a child table. "Every server with this tag" is an
index lookup instead of a decode of every row, and
ON DELETE CASCADEcleansup after a deleted server instead of the six hand-written calls in
delServer— and the four it forgot.

HiveImport(m003) now produces exactly one shape — rows inkv— instead ofthree, and no longer reaches through today's store objects. That decoupling is
what lets
KvToTablesMigration(m004) own every table, and it drops therename-aside dance entirely. The schema is created when the database is
opened, which is what keeps m004 inside one synchronous transaction: creating
it means opening Drift, which is async, and a sync transaction block cannot
await.
m004 also absorbs the two per-launch fixups.
migrateIdsandmigrateIdentityFilePathsscanned every server on every launch to repair ashape only an upgrading install can hold, and neither could have run after m004
anyway — an empty
Spi.idhas nowhere to live once the id is a primary key.Tests

test/hive_release_migration_test.dart— the whole upgrade against1466/1480/1491 fixtures,
HiveImportand m004. Asserting between the twowould only prove the data reached a shape no build ships. This is what found
the four field-name bugs above.
test/hive_import_test.dart— the import's own mechanics, seeded through thereleased layouts rather than today's models.
Not in this PR
Incremental sync and the password-wrapped DEK, both discussed and deliberately
separate — one changes the sync protocol and the remote file format, the other
changes the launch path.
