Campaign Prompt + +You are operating in the Maestro repository. + +Your mission is to run a full test coverage and test-quality campaign, not a quick patch. The target is 100% meaningful test coverage with a defensible assessment that the tests are comprehensive, behaviorally useful, and capable of catching regressions. + +## Operating Principles + +Follow these constraints: + +- Do not fake coverage by deleting source from coverage, excluding risky files, or adding import-only tests. +- Do not chase 100% line coverage at the expense of meaningful assertions. +- Treat uncovered critical paths as product risk, not just metric gaps. +- Preserve existing user changes. Do not revert unrelated dirty files. +- Prefer focused seams and reusable test helpers over brittle mega-tests. +- Add integration and E2E coverage where unit tests cannot prove behavior. +- Keep changes incremental and continuously validated. +- When a production module is hard to test, first evaluate whether it needs a small testability seam. Keep such refactors minimal and behavior-preserving. +- Never introduce broad refactors just to make tests easier. + +## Campaign Context + +Start from the branch or worktree provided by the user. Do not assume a fixed local path, branch name, baseline percentage, or previously completed test set. + +At the start of the campaign, capture the current state: + +- `git status --short --branch` +- `npm run test:coverage` +- current statement, branch, function, and line coverage from the generated coverage report +- the current list of low-coverage and zero-coverage files +- the current validation status for lint, ESLint, unit tests, coverage, integration tests, and E2E tests + +Record this fresh baseline in `docs/test-coverage-audit.md`. Treat any existing numbers in older notes as historical context only, not as authoritative campaign state. + +Existing unrelated dirty/untracked files may be present. Leave them alone unless explicitly needed. + +## Definition Of Done + +The campaign is complete only when all of these are true: + +1. `npm run test:coverage` reports 100% for statements, branches, functions, and lines, or every remaining uncovered item has a documented, justified, narrowly scoped exclusion approved by repo policy. +2. Coverage thresholds are enforced in `vitest.config.mts` so regressions fail CI. +3. Critical workflows have integration or E2E coverage, not just shallow unit coverage. +4. High-risk error paths are tested: failed IPC calls, malformed files, missing binaries, SSH failures, failed process spawns, storage corruption, permission errors, and network/websocket failures. +5. Existing noisy tests are cleaned up enough that CI output makes real failures visible. +6. The final audit document identifies what was tested, what risks remain, and why remaining exclusions are legitimate. +7. `npm run lint`, `npm run lint:eslint`, `npm run test`, `npm run test:coverage`, and relevant integration/E2E commands pass or have documented environmental blockers. + +## Phase 1: Establish Baseline And Policy + +Start by collecting hard data: + +1. Run `git status --short --branch`. +2. Run `npm run test:coverage`. +3. Parse `coverage/coverage-final.json` and produce ranked lists: + - Files with 0% statements + - Files with the most missed statements + - Files with the worst branch coverage + - Files with high risk and low coverage +4. Inspect `vitest.config.mts`, `vitest.integration.config.ts`, `playwright.config.ts`, and package scripts. +5. Decide a coverage policy: + - Include production code that contains behavior. + - Exclude generated files, type-only files, and pure barrel files only when they truly contain no runtime behavior. + - Document each exclusion with a reason. +6. Add or update coverage thresholds only when the suite is ready, or add staged thresholds if the campaign will be split into multiple PRs. + +Deliverable: update `docs/test-coverage-audit.md` with the current baseline, coverage policy, and ranked gap list. + +## Phase 2: Clean Test Signal + +Before adding hundreds of tests, reduce noise that hides failures. + +Address systemic issues seen during coverage runs: + +- React `act(...)` warnings in renderer tests. +- Expected-error tests that allow unsuppressed `console.error`, logger noise, or stack traces. +- Canvas mocks missing methods used by tested components, such as `ctx.scale`. +- Web config tests repeatedly logging development fallback warnings. +- Tests that assert only rendering presence without behavior. + +Do not silence logs globally unless the test explicitly expects that behavior. Prefer local spies and assertions: + +```ts +const consoleError = vi.spyOn(console, 'error').mockImplementation(() => {}); +expect(consoleError).toHaveBeenCalledWith(...); +``` + +Deliverable: CI/test output should be materially quieter without hiding unexpected failures. + +## Phase 3: High-ROI Unit Coverage + +Work module by module. For each module: + +1. Read the source. +2. Identify public behavior and failure modes. +3. Search existing tests before adding new ones. +4. Add tests using existing local patterns. +5. Run the specific test file. +6. Run affected broader test groups. +7. Re-check coverage for that module. + +Prioritize pure or semi-pure modules first, because they provide reliable coverage quickly: + +- `src/renderer/utils/*` +- `src/shared/*` +- parser modules under `src/main/parsers/*` +- process-manager utilities under `src/main/process-manager/utils/*` +- renderer service wrappers under `src/renderer/services/*` +- web hooks under `src/web/hooks/*` +- simple state stores under `src/renderer/stores/*` + +Test required cases: + +- happy path +- null/undefined or missing data +- malformed data +- empty collections +- boundary values +- concurrent or repeated calls where state/caching exists +- thrown dependencies +- cleanup/unsubscribe behavior + +Avoid meaningless tests: + +- Do not assert that a function exists. +- Do not test implementation details unless the module contract is implementation-specific. +- Do not snapshot large UI trees as primary coverage. +- Do not add tests that only import a module to mark it covered. + +## Phase 4: IPC Handler Coverage + +IPC handlers are high-risk because they connect UI intent to filesystem/process behavior. + +Prioritize handlers with low coverage and high blast radius: + +- `src/main/ipc/handlers/claude.ts` +- `src/main/ipc/handlers/agentSessions.ts` +- `src/main/ipc/handlers/context.ts` +- `src/main/ipc/handlers/documentGraph.ts` +- `src/main/ipc/handlers/symphony.ts` +- `src/main/ipc/handlers/process.ts` +- `src/main/ipc/handlers/git.ts` +- `src/main/ipc/handlers/filesystem.ts` + +For each handler: + +1. Verify registration and exported seams. +2. Mock Electron IPC and dependencies using existing helper patterns. +3. Test success payloads. +4. Test expected recoverable failures. +5. Test unexpected failures only when the code is meant to catch/report them. +6. Verify Sentry/logging behavior when relevant. +7. Verify path restrictions and SSH propagation where applicable. + +Do not swallow unexpected errors in production code just to make tests easy. This codebase prefers unexpected crashes to reach Sentry unless the failure is recoverable. + +## Phase 5: Storage And Provider Session Coverage + +High-impact missed coverage exists in storage implementations: + +- `src/main/storage/codex-session-storage.ts` +- `src/main/storage/opencode-session-storage.ts` +- `src/main/storage/claude-session-storage.ts` +- `src/main/storage/factory-droid-session-storage.ts` + +These tests must prove real behavior: + +- session listing +- pagination +- search modes +- malformed JSON/JSONL handling +- missing session files +- deletion semantics +- provider-specific path resolution +- SSH remote reads +- unsupported SSH write/delete paths +- corrupted metadata +- date directory traversal +- sorting and timestamp fallback + +Use temporary directories inside the test harness. Do not depend on the userโ€™s real provider history. + +## Phase 6: Renderer Component And Hook Coverage + +Prioritize large, central, low-coverage files: + +- `src/renderer/App.tsx` +- `src/renderer/components/FilePreview.tsx` +- `src/renderer/components/DocumentGraph/MindMap.tsx` +- `src/renderer/components/DocumentGraph/DocumentGraphView.tsx` +- `src/renderer/components/MarketplaceModal.tsx` +- `src/renderer/components/Settings/SshRemoteModal.tsx` +- `src/renderer/components/Wizard/screens/PreparingPlanScreen.tsx` +- `src/renderer/components/NewInstanceModal.tsx` +- `src/renderer/hooks/keyboard/useMainKeyboardHandler.ts` +- `src/renderer/hooks/session/useBatchedSessionUpdates.ts` +- `src/renderer/hooks/ui/useAppHandlers.ts` + +For UI tests, prefer user-visible behavior: + +- renders the correct state +- keyboard navigation +- escape/close behavior through layer stack +- async loading states +- error states +- disabled states +- persistence calls +- IPC call parameters +- cleanup/unsubscribe on unmount +- accessibility roles/names where applicable + +Use React Testing Library with `userEvent` where possible. Wrap async expectations with `await waitFor(...)` instead of relying on immediate assertions after state changes. + +## Phase 7: Electron Main And Web Server Coverage + +The main entry and server surfaces need careful seam work: + +- `src/main/index.ts` +- `src/main/web-server/WebServer.ts` +- `src/main/web-server/web-server-factory.ts` +- app lifecycle modules +- update checker +- auto updater + +If direct testing is difficult, extract minimal pure registration/build functions and test those. Keep runtime behavior unchanged. + +Required coverage: + +- IPC registration table includes expected handlers. +- app startup initializes required stores/services. +- server startup registers routes/websocket handlers. +- server handles port conflicts and shutdown. +- websocket broadcast paths handle disconnected clients. +- update checks handle success, unavailable update, network failure, and disabled update state. + +## Phase 8: Integration Tests + +Run and expand `npm run test:integration` where practical. + +Integration tests should cover: + +- group chat orchestration +- process global env vars +- provider integration boundaries +- Auto Run batch/session/list flows +- remote-control sync +- Inline Wizard flow +- Symphony runner flow + +Avoid brittle real-agent tests in normal unit suites. Gate slow or environment-dependent integration tests through the integration config. + +## Phase 9: E2E Tests + +Use Playwright/Electron E2E for critical user workflows that unit tests cannot prove. + +Critical E2E flows: + +- create agent +- send prompt +- interrupt process +- switch tabs +- file preview open/close +- settings persistence +- SSH remote configuration validation +- Auto Run document selection and execution +- history view and detail open +- web/mobile remote control connection if environment supports it + +Use screenshots/traces only for failures. Keep E2E tests deterministic and isolate app data. + +## Phase 10: Mutation/Fault-Injection Review + +Coverage does not prove comprehensiveness. For high-risk modules, manually perform fault-injection review: + +- Flip important booleans and confirm tests fail. +- Remove error handling and confirm tests fail where expected. +- Change IPC channel names and confirm tests fail. +- Change parser patterns and confirm tests fail. +- Break SSH wrapping and confirm tests fail. +- Break storage sort order or pagination and confirm tests fail. + +Document weak tests that survive obvious mutations. + +## Completion Workflow + +Repeat this loop until coverage and quality goals are met: + +1. Pick one module or feature area. +2. Read source and existing tests. +3. Write meaningful tests. +4. Run the specific test file. +5. Run relevant grouped tests. +6. Run `npm run test:coverage`. +7. Update audit doc with coverage movement and remaining risk. +8. Fix noisy or flaky tests encountered in touched areas. +9. Run `npm run lint` and `npm run lint:eslint`. + +Before final delivery, run: + +```bash +npm run format:check:all +npm run lint +npm run lint:eslint +npm run test +npm run test:coverage +npm run test:integration +npm run test:e2e +``` + +If integration or E2E tests require unavailable environment dependencies, document the exact blocker, command output summary, and what remains unverified. + +## Final Response Requirements + +Final response must include: + +- Coverage before/after table. +- List of files added/modified. +- Test commands run and results. +- Any commands not run and why. +- Remaining exclusions, if any, with justification. +- Test-quality assessment: where tests are strong, where they remain weak, and which workflows are covered only by unit tests versus integration/E2E. + +Do not claim โ€œ100% coverageโ€ unless the coverage report enforces and confirms 100% statements, branches, functions, and lines. diff --git a/docs/full-test-coverage-session-handoff.md b/docs/full-test-coverage-session-handoff.md new file mode 100644 index 0000000000..abbe2002d3 --- /dev/null +++ b/docs/full-test-coverage-session-handoff.md @@ -0,0 +1,791 @@ +# Full Test Coverage Session Handoff + +Last updated: 2026-05-21 + +## How To Resume In A New Trusted-Hooks Session + +The active goal in the old Codex thread is a compressed summary.

+- Many renderer tests emit React `act(...)` warnings, meaning some assertions may run before user-visible state has settled. +- Several tests intentionally trigger error paths but allow console

startup, SSH remote paths, and web server behavior. +- Current coverage config includes barrel, type-only, entrypoint, and app-shell files that may need explicit policy decisions instead of accidental 0% coverage. +- E2E coverage is separate from unit coverage and is not reflected in `vitest --coverage`; critical Electron workflows need both Playwright assertions and unit-level seams. + +## Phase 2

+- Missing-session and undefined-array fallbacks while creating tabs and building

+- Positioned tab creation when the target tab is missing, already adjacent, or
+  requires reordering.
+- Unread-only close behavior that selects the previous unread tab or falls back
+  to positional selection when no unread tabs remain.
+- File-tab close fallbacks when the active file tab is missing from
+  `unifiedTabOrder`, including first-file, first-AI, and no-tab outcomes.
+- Unified-history AI restore insertion in a mixed file/AI order.

+- One uncovered statement remains at `getCurrentUnifiedTabIndex` line 1375. The

+- Grooming format behavior for stripped long file reads, preserved short file
+  reads, command-output headers, summary headers, and markdown fences.
+- Token estimation and async token counting for usage stats, missing stat
+  fields, image overhead, no-image logs, and contexts without logs.
+- Duplicate-content detection for full duplicates, code-block duplicates, small
+  repeated code blocks, unique content, and contexts without logs.
+- Clipboard formatting filters and context summary counts for mixed and no-log

+- One uncovered branch remains at line 304 in the Read-tool code-block stripping

+## Phase 3 Coverage Checkpoint: File Explorer Icon Themes
+
+Added `src/__tests__/renderer/utils/fileExplorerIcons.test.tsx` for the icon
+theme helpers under `src/renderer/utils/fileExplorerIcons/`.

+- Default file-change color routing for added, deleted, modified, and unchanged
+  files.
+- Default folder icon mapping for git, docs, tests, config, assets,
+  dependencies, data, secure, infrastructure, and generic open/closed folders.
+- Rich file icon mapping for README/license/package managers, lockfiles, git
+  files, Node/Docker/schema files, test-file families, TypeScript/React/JS/JSON/
+  YAML/config/HTML/CSS/docs/image/archive/database/code/generic files.

+- Duplicate wiki-link filename resolution when partial paths match exactly one

+- Empty-index operation when neither `fileTree` nor prebuilt indices are
+  supplied.
+- First-token replacement without inserting leading empty text.
+- Absolute paths under project roots with and without trailing slashes, absolute
+  paths outside the project root, and absolute paths embedded inside wiki-link
+  display text without double conversion.
+- Inline-code wiki links, unresolved wiki links, absolute paths with unsupported
+  extensions, absolute paths outside project root, existing relative paths, and
+  missing relative paths.
+- Image embeds with project-root `file://` URLs and FilePreview-style relative
+  image paths when no `projectRoot` is supplied.
+- Standard markdown links converted to `maestro-file://`, URL-decoded relative
+  links, unresolved relative links, protocol/anchor/empty-href skips, and
+  preservation of existing `hProperties` while adding `data-maestro-file`.

+- Lines 259 and 491 are defensive `!parent || index === undefined` visitor
+  guards. Valid mdast traversal through `unist-util-visit` supplies parent/index
+  for text and inline-code children, so these were not forced with invalid trees.
+- Line 248 is the `toRelativePath` no-`projectRoot` guard. Current call sites
+  only invoke `toRelativePath` inside `projectRoot` checks, so this branch is not
+  reachable through public plugin input.

+Remaining `markdownLinkParser` risk:
+
+- Line 29 is the private `extname` empty-path guard. Public link parsing already

+- Line 66 is the private `joinPath` empty-result fallback. Public relative path
+  resolution does not currently expose an empty result without first producing a
+  valid normalized path.
+- Lines 315 and 316 are the private `resolveRelativePath` empty/non-string guard.
+  Regex extraction supplies string link paths, and empty markdown URLs are not
+  matched by the parser.
+- Lines 342 and 343 are cleanup for paths starting with `./` after joining.
+  `joinPath` removes `.` segments before this point for public inputs.
+- Line 442 is the markdown-link empty URL guard. The markdown link regex requires

+## Phase 3 Coverage Checkpoint: Inline Wizard Document Generation
+

+Behavior covered:
+
+- Streaming display extraction for Claude Code, OpenCode, Codex, malformed JSON,
+  and unsupported chunks.
+- Document marker parsing edge cases, phase splitting, filename sanitization,
+  task counting, iterate prompt defaults, existing-document prompt content, and
+  conversation-role filtering.
+- Agent availability failures, missing local agents, remote generation without a
+  local agent, spawn rejection, non-zero process exits, raw-output preservation,
+  and generation timeouts with process kill.
+- Stream-json result extraction for OpenCode, Claude Code, and Codex.
+- Agent argument construction for Claude Code, Codex, OpenCode, and custom agent
+  ids.
+- Unique Auto Run subfolder naming, list failure fallback, marker parsing,
+  plain-output phase splitting, disk fallback reads, disk fallback exceptions,
+  and no-document failures.
+- File-watcher document discovery, duplicate watcher events, watcher read retry
+  failure, watcher setup failure/rejection, SSH propagation through existing
+  tests, partial save failure, all-save failure, playbook creation, and playbook
+  creation failure.
+- Expected logger/console output in the renderer-services group is now locally
+  spied or asserted, making the group output quiet.

+- Message reads across legacy `message`, current `response_item` messages,
+  function calls, function-call output, legacy `item.completed` agent messages,
+  byte-array tool results, and reverse-window pagination.
+- Local deletion semantics for user/assistant pairs, tool-call cleanup,
+  fallback-content deletion, missing user messages, SSH delete rejection, and
+  null synchronous session paths.

+  legacy metadata fallback variants, and additional delete edge cases.
+- The current tests use mocked filesystem and SSH APIs to avoid the user's real

+- JSON session listing with assistant-preferred preview, message counts, token
+  and cache aggregation, cost aggregation, duration calculation, file-size
+  stat reads, and modified-date sorting.
+- Message reads from message/part directories, text extraction, tool part
+  attachment, pagination, and inherited search behavior.
+- JSON deletion semantics: user/assistant pair deletion until the next user,
+  associated part-file deletion, fallback-content deletion, missing-message
+  failure, orphaned tool-reference cleanup, and SSH delete rejection.

+- SQLite-backed OpenCode v1.2+ paths remain only lightly covered by older

+  newest-first sorting.
+- Missing local project directories returning empty results with expected
+  logging.
+- Local message reads with string content, text-array content, tool-use and
+  tool-result preservation, reverse-window pagination, and inherited search
+  behavior.
+- Local deletion by UUID and fallback content, including removal through the
+  following assistant/non-user records, preservation of malformed lines and the
+  next user turn, missing-message failures, read-failure Sentry capture, and
+  SSH delete rejection.
+- Local and remote session path resolution.

+- Local Claude JSONL listing under `~/.claude/projects`, including encoded
+  project-directory resolution, non-session file filtering, malformed-line
+  tolerance, assistant-preferred previews, message counts, token aggregation,
+  cost calculation, duration calculation, origin/session-name/starred metadata,

+- Remote SSH listing through `readDirRemote`, `statRemote`, and
+  `readFileRemote`, including directory filtering, stat failures, read
+  failures, oversized remote files, and remote cursor pagination.
+- Local and remote message reads with string content, text blocks, tool-use
+  preservation, malformed-line skipping, reverse-window pagination, and remote
+  read failure fallback.
+- Inherited search behavior across local Claude sessions.
+- Local deletion by UUID and fallback content, orphan `tool_result` cleanup
+  when deleting a corresponding assistant `tool_use`, missing-message

+- Enabled SSH remote lookup through the settings store and propagation to

+- Named-session aggregation across providers, including providers without

+- Project stats cache behavior, including reuse of unchanged cached sessions,

+  changed sessions, zero-byte filtering, cache writes, and progressive
+  `claude:projectStatsUpdate` sends.
+- Project stats missing-directory fallback to zero totals.
+- Session timestamp lookup from stats cache, null timestamp filtering, fallback
+  filesystem mtime scans, and skipped stat failures.
+- Legacy global stats behavior, including valid cache reuse, dropped stale
+  cache entries, project-directory traversal, non-directory and zero-byte
+  filtering, per-session parse failure tolerance, global cache writes, and
+  progressive `claude:globalStatsUpdate` sends.
+- Legacy global stats missing-directory fallback to complete zero totals.
+- Slash-command discovery across user commands, project commands, and enabled
+  plugin commands, including YAML frontmatter skipping, plugin prefixes,
+  disabled plugin filtering, and unreadable command description fallback.
+- Skill discovery across project and user skill folders, frontmatter
+  name/description parsing, fallback metadata, token count approximation, and
+  unreadable skill skipping.
+- Claude session origin metadata handlers for registration, session-name
+  updates, starred updates, context-usage updates, missing-session default
+  metadata creation, project origin lookup, and named-session aggregation with
+  best-effort last-activity stats.

+- Local suppression/assertion of expected registration `console.log` output so
+  the new suite does not add CI noise.
+- Stored-session retrieval through provider session storage, including missing
+  storage and read-failure fallbacks to `null`.
+- Single-call grooming delegation to the shared `groomContext` utility with SSH
+  remote config, session custom path/args/env, and agent-level config values
+  from the store.
+- Missing process-manager dependency failure for single-call grooming.
+- Cancel-all forwarding to the shared groomer utility.
+- Legacy grooming session lifecycle: available-agent lookup, spawn config,
+  active-session tracking, cleanup through IPC, unavailable-agent failure, and
+  failed-spawn failure.
+- Event-driven prompt flow: matching data collection, unrelated-session data
+  ignoring, exit completion, write failure, agent-error rejection, idle-timeout
+  completion with enough content, empty overall-timeout rejection, listener
+  cleanup, global cleanup, and kill-failure tolerance.

+- Per-root debounce batching into one `documentGraph:filesChanged` renderer
+  notification.
+- Same-file event replacement inside the debounce window.
+- No-renderer-window suppression that clears pending events without sending.
+- Replacing an existing watcher for the same root, including closing the old
+  watcher and clearing pending debounce work.
+- Idempotent unwatch behavior and pending timer cleanup.
+- App `before-quit` cleanup for multiple active watchers and pending debounce
+  timers.
+- Watcher error logging without tearing down the active watcher.

+- Fresh GitHub Search API count fetching when no cache is available.
+- Counting search results per requested repository while ignoring unrequested
+  repositories returned by GitHub.
+- Persisting fresh counts with a sorted unique repo-slug cache key.
+- Search API request headers and query construction for the Symphony label and
+  multiple `repo:` qualifiers.
+- Pagination across full 100-item pages until a partial page is returned.
+- Empty repo-list behavior without a network request.
+- Expired-cache fallback when GitHub Search fails.

+- Remote directory sizing success, remote count fallback to zero, remote size
+  failure, and missing SSH remote handling.
+- Local and remote write, rename, delete, and count operations, including

+- Remaining branch gaps are optional/default-expression branches around logging,

+- Tests mock the process manager, agent detector, settings stores, SSH command

+## Phase 4 Coverage Checkpoint: Speckit IPC Handler
+
+Added `src/__tests__/main/ipc/handlers/speckit.test.ts` for

+
+- Registration for all six Spec Kit IPC channels:
+  `speckit:getMetadata`, `speckit:getPrompts`, `speckit:getCommand`,
+  `speckit:savePrompt`, `speckit:resetPrompt`, and `speckit:refresh`.
+- Metadata and prompt-list success payloads from the Spec Kit manager.
+- Slash-command lookup for both known commands and unknown-command `null`
+  responses.
+- Prompt customization save behavior, including manager arguments and expected
+  audit logging.
+- Prompt reset behavior, including returned default prompt and expected audit
+  logging.
+- Refresh behavior, including metadata payload and source-version logging.
+- Recoverable manager failures for metadata loading, prompt loading, save,
+  reset, and refresh operations.

+## Phase 4 Coverage Checkpoint: IPC Handler Registration Table
+
+Added `src/__tests__/main/ipc/handlers/index.test.ts` for

+
+Behavior covered:
+
+- `registerAllHandlers` invokes the consolidated handler registration sequence
+  in the expected order.
+- Dependency-backed handlers receive only the dependency slice they own,
+  including git, agents, process, persistence, system, Claude, group chat,
+  debug, context, stats, document graph, SSH remote, attachments, leaderboard,
+  Symphony, tab naming, Director's Notes, and logger event forwarding.
+- Dependency-free handlers are registered without arguments: history, Speckit,
+  OpenSpec, filesystem, notifications, and agent error.
+- Lifecycle-specific handlers not owned by `registerAllHandlers` are not called
+  from this helper: agent sessions, web server handlers, and WakaTime.

+
+Remaining handler registration risk:
+
+- The test mocks every registered handler module. It proves consolidated wiring,
+  order, and dependency shaping but does not execute individual handler
+  registrations or Electron `ipcMain.handle` calls.
+- `registerAllHandlers` is not currently called by `src/main/index.ts`; the main
+  entrypoint still registers handlers directly. The test therefore covers this
+  exported helper as a registration contract, not the production boot path.
+- No production refactor or coverage exclusion was made in this checkpoint.

+## Phase 4 Coverage Checkpoint: Symphony Validation And Issue Enrichment
+
+Expanded `src/__tests__/main/ipc/handlers/symphony.test.ts` for targeted
+high-risk validation and GitHub enrichment paths in
+`src/main/ipc/handlers/symphony.ts`.
+
+Behavior covered:
+
+- Oversized issue bodies are truncated before document-path parsing and emit an
+  expected warning with the original body length and parser limit.
+- GitHub PR enrichment marks issues as `in_progress` when an open PR references
+  the issue number and records the PR number, URL, author, and draft state.
+- PR enrichment failures are non-fatal: failed PR API responses and thrown PR
+  API errors leave issues available and log the expected warning.
+- Empty issue lists skip PR enrichment and avoid an unnecessary second GitHub
+  request.
+- `symphony:start` rejects malformed `owner/repo` slugs, missing repo names,
+  and unsafe external document URLs.
+- `symphony:startContribution` rejects malformed `owner/repo` slugs and unsafe
+  external document URLs before authentication, git, branch, or file operations.

+- Tests still mock GitHub API responses, git/gh command execution, filesystem

+## Phase 4 Coverage Checkpoint: Symphony Registry And Star Counts
+
+Expanded `src/__tests__/main/ipc/handlers/symphony.test.ts` for registry fetch,
+registry fallback, and repository star-count behavior in
+`src/main/ipc/handlers/symphony.ts`.
+
+Behavior covered:
+
+- Cached registries are enriched with valid cached star counts without hitting
+  GitHub.
+- Fresh registry fetches request star counts only for active repositories,
+  attach the returned count to the registry response, and persist the star cache.
+- Star-count requests that return non-OK responses are treated as zero stars.
+- Missing `stargazers_count` fields default to zero rather than leaking
+  `undefined` into the UI payload.
+- Non-OK registry responses and malformed registry payloads fail with useful IPC
+  errors when no cache is available.
+- Expired registry cache is used as a fallback when fresh registry fetch fails,
+  including cached star enrichment and cache-age reporting.

+## Phase 4 Coverage Checkpoint: Auto Run SSH Documents
+
+Expanded `src/__tests__/main/ipc/handlers/autorun.test.ts` for SSH-backed Auto
+Run document operations in `src/main/ipc/handlers/autorun.ts`.
+
+Behavior covered:
+
+- `autorun:listDocs` recursively scans remote directories, excludes hidden
+  entries and symlinks, includes nested markdown documents, preserves folder
+  tree shape, and bypasses local `fs.stat`.
+- Remote directory-read failures return an empty document list and log the
+  expected warning instead of failing the whole listing operation.
+- `autorun:readDoc` reads nested remote markdown files through `readFileRemote`
+  and reports remote read failures.
+- `autorun:writeDoc` creates missing remote parent directories before writing
+  nested documents and does not touch local filesystem writes.
+- Remote parent directory creation failures stop the write and avoid calling
+  `writeFileRemote`.
+- Expected `writeDoc` debug `console.log` output is now suppressed locally in
+  writeDoc-related tests, making Auto Run handler output quiet without global log
+  silencing.

+
+Expanded `src/__tests__/main/ipc/handlers/agents.test.ts` for SSH-backed agent

+
+Behavior covered:
+
+- `agents:detect` returns all known agents as unavailable when a selected SSH
+  remote configuration is missing, without calling local detection or SSH.
+- Remote detection uses disabled-but-explicitly-selected remotes, matching the
+  handler contract that explicit remotes are attempted even when `enabled` is
+  false.
+- Remote detection distinguishes available binaries, missing binaries, SSH
+  stderr connection failures, and per-agent thrown SSH command failures.
+- Remote detection strips function properties and preserves per-agent
+  capabilities and error details.
+- `agents:get` returns an unavailable agent definition when remote config is
+  missing and the agent ID is known.
+- `agents:get` detects a specific agent over SSH and bypasses the local detector.
+- `agents:get` converts SSH command-builder failures into an unavailable agent
+  with a recoverable error payload.

+- Unknown remote model agent IDs return an empty model list without building or

+
+Expanded `src/__tests__/main/ipc/handlers/groupChat.test.ts` for the remaining

+
+Behavior covered:

+- `groupChat:archive` stops moderator and participant sessions before archiving,
+  and unarchives without stopping already-inactive sessions.
+- Missing-chat error paths now cover `groupChat:getMessages`,
+  `groupChat:saveImage`, and `groupChat:startModerator`.
+- `groupChat:resetParticipantContext` covers successful context summarization,
+  participant session reset, renderer participant-change notification, summary
+  generation failure fallback, missing chat, missing participant, missing process
+  manager, and missing agent detector.
+- `groupChat:getImages` now reads real temporary image files, emits correct data
+  URL MIME prefixes, ignores non-images, returns `{}` for missing image
+  directories, and warns on non-ENOENT directory read failures.
+- Renderer event emitters now verify participant changes, moderator usage,
+  history entries, participant state, moderator session IDs, Auto Run trigger and
+  completion events, and live participant output.
+- Expected Group Chat debug `console.log`/`console.warn` output is suppressed
+  locally in the tests that trigger it, removing the Group Chat stdout noise from
+  the grouped IPC handler run.

+- Non-zero command exits with captured stderr and logged process error output.
+- Child process `error` events, long text preview truncation, close events after
+  an already-resolved spawn failure, and active-process cleanup.
+- Stdin `EPIPE`, non-`EPIPE`, non-object stdin errors, write callback errors,
+  missing stdin, and missing stderr stream behavior.
+- Queue delay enforcement between back-to-back notification commands.
+- Stop semantics for active processes, missing notification IDs, and kill

+- Stats collection disabled via `settingsStore.get('statsCollectionEnabled')`

+- Sync migration records non-`Error` copy failures.
+- Power management restores persisted sleep-prevention state, persists toggles,

+
+Behavior covered:
+
+- `context:groomContext` passes an empty agent config when no saved provider
+  config exists.
+- Legacy grooming sessions spawn with empty args when an agent has no configured
+  args.
+- Prompt sending rejects unknown grooming sessions before registering process
+  listeners.
+- Stale or duplicate process events after response resolution are ignored.
+- Agent-error events support both `Error` objects and non-`Error` payloads.
+- Overall timeout returns partial output when the process produced content but
+  did not reach the idle-response threshold.
+- Sessions tracked before timeout setup completes can still be cleaned up if
+  timer setup throws.
+- `context:sendGroomingPrompt` registration failures are logged and do not
+  prevent later handler registration.

+  groomer. They prove IPC-visible stored-session reads, single-call grooming
+  argument propagation, cancellation, legacy session creation, prompt write,

+
+## Phase 4 Coverage Checkpoint: Tab Naming IPC SSH And Timeout Paths
+
+Expanded `src/__tests__/main/ipc/handlers/tabNaming.test.ts` and removed an
+unreachable truncation branch from `src/main/ipc/handlers/tabNaming.ts` because
+`extractTabName` already filters out candidate lines longer than 40 characters
+before that branch could run.
+
+Behavior covered:
+
+- Agents without a local `path` or configured `args` use their command and an
+  empty args array.
+- Session SSH config with a missing `remoteId` or unresolved remote config falls
+  back to local execution instead of wrapping the command.
+- SSH execution without stream-json stdin support uses command-line args and
+  keeps `sendPromptViaStdin` false.
+- SSH execution with stream-json stdin support appends missing
+  `--input-format stream-json` args and avoids duplicating them when already
+  present.
+- Completed tab naming requests ignore late timeout and exit events.
+- Configuration resolution failures return `null` and tolerate cleanup kill
+  failures.

+- Submit, auth polling, resend confirmation, leaderboard fetch, longest-runs

+  rejected values.
+- Auth polling falls back to `Server error: ` when an error response
+  omits a message.
+- Confirmation resend uses its default success message, message fallback,
+  server-error fallback, timeout path, and unknown-error path.
+- Sync uses default not-found, invalid-token, email-not-confirmed,
+  missing-fields, generic server-error, explicit server-error, timeout, and
+  unknown-error paths.

+debug, and slash-command fallback paths.
+
+Behavior covered:
+
+- Remote detection returns unavailable agents when no settings store is present,
+  and does not call the local detector or SSH command builder.
+- Remote detection preserves SSH connection failures, string rejection payloads,
+  summary logging for failed remotes, per-agent timeout handling, and non-SSH
+  command failures that should not count as successful connectivity.
+- Single-agent SSH lookup rejects unknown agent IDs before remote execution,
+  surfaces each supported SSH connection stderr marker, stringifies non-`Error`
+  setup failures, and returns unavailable results on timeouts.
+- Refresh debug output uses request-agent fallbacks when the detector does not
+  return the requested agent, including empty `PATH`/`HOME` and the
+  `Binary not found in PATH` fallback.
+- Agent config reads merge `configOptions` defaults with stored values, and
+  single-value reads fall back to default config options.
+- Remote model discovery covers the actual timeout race path and the default
+  `forceRefresh` value for SSH calls.
+- Slash command discovery falls back to `agent.command` when no custom path or
+  detected path is available.

+
+## Phase 4 Coverage Checkpoint: Notifications IPC Queue And Logging
+
+Expanded `src/__tests__/main/ipc/handlers/notifications.test.ts` and made a
+minimal behavior-preserving cleanup in `src/main/ipc/handlers/notifications.ts`
+for unreachable defensive branches inside the internal notification execution
+path.
+
+Behavior covered:
+
+- Command request logging truncates very long text previews at the request-log
+  boundary.
+- Late child-process `error` events after a command has already closed are
+  logged but do not override the resolved success result.
+- Existing coverage continues to prove OS notification success/failure, command
+  parsing, arbitrary command pass-through, stdin errors, stderr capture,
+  renderer completion notifications, queue delay behavior, queue capacity
+  rejection, stop/kill behavior, and state reset utilities.
+
+Production cleanup:
+
+- Removed fallback `(no text)` preview branches and optional text-length
+  handling from `executeNotificationCommand`. The public
+  `notification:speak` handler already returns before queueing empty, null, or
+  undefined text, and the internal queue item type is `string`.
+- Removed the second queue-empty check immediately after setting
+  `isNotificationProcessing`. There is no await or external interleaving point
+  between the first queue check, the processing flag assignment, and the queue
+  shift, so the branch was unreachable through the module contract.
+- No behavior was broadened and no coverage exclusion was added.

+
+## Phase 4 Coverage Checkpoint: Agent Sessions IPC SSH, Origins, And Stats Cache
+
+Expanded `src/__tests__/main/ipc/handlers/agentSessions.test.ts` and made a
+minimal behavior-preserving cleanup in `src/main/ipc/handlers/agentSessions.ts`
+for dead cache-provider fallbacks.
+
+Behavior covered:
+
+- Paginated list, read, and search handlers resolve enabled SSH remotes from the
+  settings store and pass the resulting config to provider storage.
+- Generic origins handlers no-op safely when the origins store is unavailable,
+  return empty maps for missing agent/project buckets, create missing
+  agent/project buckets for names and stars, and clean empty metadata entries
+  without deleting entries that still have origin data.
+- Global stats returns an empty complete result when Claude/Codex history roots
+  are missing.
+- Global stats discovery skips invalid Codex year/month/day folders,
+  non-directory date folders, non-JSONL files, zero-byte files, and files that
+  fail stat.
+- Codex stats parsing handles malformed JSONL, non-user/assistant message
+  roles, missing token usage, and empty token usage fields.
+- Existing cached sessions are archived when source files disappear, restored
+  when archived files reappear, and left active when active files remain
+  present.
+- Individual Claude/Codex parse failures are logged and do not stop remaining
+  global stats processing.
+
+Production cleanup:
+
+- Removed optional `?.sessions || {}` fallbacks inside global stats aggregation.
+  Provider entries are created before any aggregation or archive walk, and the
+  old fallback did not protect malformed provider entries from earlier
+  `Object.keys(provider.sessions)` access. The cleanup removes dead branches
+  without changing valid-cache behavior.
+- No coverage exclusion was added.

+
+## Phase 4 Coverage Checkpoint: Claude IPC Sessions, Search, Stats, Commands, And Origins
+
+Expanded `src/__tests__/main/ipc/handlers/claude.test.ts` and made a minimal
+behavior-preserving cleanup in `src/main/ipc/handlers/claude.ts` for unreachable
+search preview classification.
+
+Behavior covered:
+
+- Session listing and paginated listing use assistant text as the first preview
+  when no user preview exists, ignore image/object/non-text content, preserve
+  stat mtime as the fallback timestamp, skip unreadable page files, and support
+  legacy string origin metadata.
+- Message reads skip truthy unsupported content shapes without dropping valid
+  neighboring messages.
+- Message-pair deletion handles fallback mismatch cases and cleans orphaned
+  tool results both when the entire user content is removed and when only part
+  of an array content block is removed.
+- Project stats handles no-cache scans, changed-cache reparsing, parse failures,
+  no renderer window, sessions with no counted messages, and no oldest
+  timestamp.
+- Session timestamp fallback returns an empty list when both cache and project
+  directory are unavailable.
+- Legacy global stats handles stale cache versions, unreadable caches, cache
+  save failures, uncached global scans with no renderer window, and sessions
+  with no counted messages.
+- Search sessions covers unsupported content objects, assistant preview
+  trimming, assistant-first previews that later become title matches, and
+  nonmatching title-mode searches.
+- Slash command discovery covers frontmatter-only commands, settings without
+  enabled plugins, and enabled plugin entries without install paths.
+- Skill discovery skips non-directory entries while preserving project/user
+  skill parsing.
+- Session origins cover existing project maps, object and string metadata
+  updates, newly created project buckets, unnamed registrations, missing project
+  origin lookups, and best-effort named-session activity timestamps.
+
+Production cleanup:
+
+- Removed the redundant `searchMode === 'user' || searchMode === 'all'` preview
+  block inside the user-match path. The title-match block runs first for the
+  same user-match condition and always creates the preview before the later
+  user-match block could do so.
+- Simplified all-mode match classification from
+  `title -> user -> assistant` to `title -> assistant`. In current code,
+  `titleMatch` is set for every user match before all-mode classification, so
+  the `user` arm was unreachable and did not represent observable behavior.
+- No coverage exclusion was added.

+  label filtering, PR enrichment matches, unmatched PRs, enrichment HTTP
+  failures, enrichment exceptions, and empty issue lists.
+- Issue-count fetching covers cache-key matching, deduped cache persistence,
+  pagination, empty repo lists, stale-cache fallback, and search failures.
+- Legacy `symphony:start` covers validation for trusted external documents,
+  safe internal documents, cleanup failure swallowing, fork setup failures, and
+  cross-fork draft PR creation.
+- `symphony:registerActive`, `updateStatus`, `complete`, and `cancel` cover
+  progress/token/status updates, no-window broadcasts, PR-ready failures,
+  PR comment body formatting, fork-aware comment posting, comment failures,
+  state transitions, stats aggregation, first-contribution preservation, weekly
+  streak transitions including Sundays, and cleanup failures.
+- `symphony:checkPRStatuses` covers malformed history entries, completed and

+
+Expanded `src/__tests__/main/ipc/handlers/autorun.test.ts` for

+- Local document scanning covers folder-before-file sorting, empty subfolder
+  pruning, dotfile filtering, nested documents, non-directory failures,

+  return once a markdown file is found.
+- Local document reads and writes cover extension handling, nested paths,
+  malformed URL-encoded filenames, missing files, traversal rejection,
+  resolved-path escape rejection, parent-directory creation, and parent-path
+  escape rejection.
+- Image APIs cover valid extension filtering, invalid extension rejection,
+  document-name sanitization, document names that remain invalid after
+  `basename`, local write/delete path escape checks, missing image folders,
+  missing image files, and local image deletion restrictions.
+- Folder deletion and watching cover missing folders, non-directory paths,
+  non-`ENOENT` stat failures treated as no-op, safety-folder-name failure,
+  local watcher creation, missing-folder creation, watcher replacement cleanup,
+  unwatch cleanup, renderer-unavailable debounced events, markdown-only event
+  emission, rapid-event debounce behavior, watcher error logging, app
+  `before-quit` cleanup, and watcher state reset between tests.
+- SSH-backed document and image operations cover remote document list/read/write
+  success, unreadable remote directories, empty remote subfolders, missing
+  remotes, existing and missing remote parent folders, remote mkdir fallback
+  errors, remote read/write fallback errors, remote image directory creation,
+  remote image write/delete/list failure fallbacks, directory and symlink
+  filtering, and unsupported local filesystem calls.
+- Backup and working-copy APIs cover local backup/restore, `.md` filename
+  variants, missing backup/source files, traversal rejection, local resolved-path
+  escapes, local Runs directory creation, nested working-copy paths, SSH
+  backup/restore/read/write/delete fallbacks, remote Runs mkdir/write fallbacks,

+- Windows spawn logging now covers prompt preview details, including hash and
+  newline detection.
+- Spawn logging now covers provider session extraction from `--resume` and
+  `--session`, long prompt truncation, model IDs, and YOLO mode flags.
+- Local spawns still succeed when no renderer window is available for SSH remote
+  status events.
+- SSH stream-json image spawns preserve an existing `--input-format stream-json`
+  pair without appending a duplicate.
+- SSH image resume spawns pass file-based image metadata and signal
+  `prompt-embed` resume mode.
+- `process:runCommand` falls back to local execution with a `null` SSH config
+  when a session SSH remote cannot be resolved.

+
+## Phase 4 Coverage Checkpoint: Group Chat IPC Handler Branch Completion
+
+Expanded `src/__tests__/main/ipc/handlers/groupChat.test.ts` for
+`src/main/ipc/handlers/groupChat.ts`.
+
+Behavior covered:
+
+- Group chat creation and moderator updates now cover reload-null fallbacks that
+  return the already-created or already-updated chat.
+- Archive, stop moderator, participant send/remove, and Auto Run completion
+  paths now cover unavailable process manager fallbacks.
+- Moderator message routing now covers long-message preview truncation,
+  unavailable runtime dependencies, and the default non-read-only log payload.
+- Participant creation now covers an unavailable agent detector while still
+  passing the rest of the add-participant contract through.
+- Participant context reset now covers a null reload after clearing the
+  participant session, avoiding a stale participants-changed emit.
+- Renderer event emitters now cover destroyed-window drops for state,
+  participants, usage, history, session, Auto Run, batch-complete, and live
+  output events.

+
+Simplified `src/main/ipc/handlers/autorun.ts` for the Auto Run document tree

+
+Behavior covered:
+
+- The internal Auto Run `TreeNode` shape now models the existing scanner
+  invariant directly: file nodes have paths, and folder nodes have child arrays.
+- `flattenTree` no longer carries an unreachable fallback for a folder node
+  without `children`. Local and SSH scanners only emit folder nodes when
+  recursive scans return children, so this removes a defensive branch that the
+  public IPC handlers cannot produce.
+- Existing list-docs tests continue to cover file nodes, folders with markdown
+  descendants, empty folders skipped by the scanner, dotfile filtering, sorting,
+  and SSH-backed directory traversal.

+
+Simplified unreachable defensive branches in `src/main/ipc/handlers/symphony.ts`

+
+Behavior covered:
+
+- Document reference parsing now relies on the existing bounded markdown path
+  patterns, which only capture paths ending in `.md`; the filename fallback for
+  an empty final path segment was unreachable and was removed.
+- The no-PR local-path branch now assigns the in-progress message directly. No
+  earlier reachable branch can set `message` while still leaving the
+  contribution without a draft PR number.
+- Merged and closed PR sync paths now remove the active contribution with an ID
+  filter. The contribution is already loaded from `state.active`, so the
+  previous `findIndex !== -1` guards were unreachable.

+
+Refactored the first `src/main/ipc/handlers/git.ts` branch slice and expanded

+
+Behavior covered:
+
+- Repeated SSH context setup for basic Git handlers now routes through
+  `resolveRemoteGitContext`, preserving the existing `remoteCwd || cwd`
+  behavior while removing duplicated branch instrumentation across status,
+  diff, repo checks, branch/tag/log/info/show, and commit-count handlers.
+- `git:status` now has explicit test coverage for SSH execution with a provided
+  remote CWD, proving the handler uses the remote repository path instead of the
+  local session path.
+- `git:log` now covers deletion-only shortstat output, keeping additions at `0`
+  when Git reports deletions without insertions.
+- `git:showFile` no longer carries an unreachable file-extension fallback:
+  `String.prototype.split('.').pop()` always returns a string for handler input.

+  root resolution.
+- `git:worktreeSetup` now covers existing-worktree metadata fallback behavior,
+  failed branch lookup defaults, and worktree creation failures without stderr.
+- `git:createPR` now covers empty shell PATHs and non-`Error` shell PATH
+  failures while preserving default subprocess environment behavior.
+- `git:checkGhCli` now covers missing custom `ghPath` checks without writing
+  default-path cache state.
+- `git:scanWorktreeDirectory` now covers SSH parent paths without trailing

+  custom env vars, and `~/` expansion for custom PTY env vars.
+- `buildChildProcessEnv` now covers stripping Electron/IDE/`NODE_ENV` values,

+- Added explicit coverage proving full-path misses use bare `powershell.exe`

+
+Updated `src/renderer/components/Settings/tabs/EncoreTab.tsx` and

+
+- The Director's Notes provider configuration panel stays hidden when settings

+- Custom environment variable creation chooses `NEW_VAR_1` when `NEW_VAR`
+  already exists, preserving the existing value.
+
+Implementation note:
+
+- Removed the redundant `directorNotesSettings.provider` guard around
+  `ac.saveAgentConfig(...)`. The config panel only renders when both the
+  selected detected agent and selected tile exist, so the guarded false path was
+  unreachable from the UI.

+
+## Phase 3 Coverage Checkpoint: Emoji Picker Field
+
+Updated `src/renderer/components/ui/EmojiPickerField.tsx` and

+Behavior covered:
+
+- Disabled emoji picker buttons do not open the picker, do not call `onOpen`,
+  and keep `aria-expanded="false"`.
+- The picker overlay and close button render correctly without optional
+  `data-testid` props.
+- Non-Escape overlay key presses leave the picker open and do not call
+  `onClose`.
+
+Implementation note:
+
+- Removed the redundant disabled guard inside `handleToggle`. The rendered
+  button already uses the native `disabled` attribute, so the click handler is
+  not invoked while disabled.

+## Phase 3 Coverage Checkpoint: CLI Watcher Non-Error Startup Failure
+
+Updated `src/__tests__/main/app-lifecycle/cli-watcher.test.ts`.

+## Phase 3 Coverage Checkpoint: Navigation History Stack Invariant Simplification
+
+Updated `src/renderer/hooks/session/useNavigationHistory.ts`.
+

+- Simplified the back/forward navigation stack transitions by encoding the

+## Phase 3 Coverage Checkpoint: Layer Stack Defensive Handler And Debug Label Paths
+
+Updated `src/__tests__/renderer/hooks/useLayerStack.test.ts`.
+
+Behavior covered:

+- Added coverage for the defensive `closeTopLayer` path where a malformed layer
+  has no registered Escape handler, verifying the layer is treated as closable

+
+## Phase 3 Coverage Checkpoint: Context Summarizer Empty Response And Chunk Guards
+
+Updated `src/__tests__/renderer/services/contextSummarizer.test.ts`.
+

+
+- Added coverage for an empty `groomContext` response, verifying the summarized

+
+## Phase 3 Coverage Checkpoint: Notification Store Unreachable Fallback Simplification
+
+Updated `src/renderer/stores/notificationStore.ts`.
+
+Behavior covered:
+
+- Replaced the unreachable custom-notification `unknown` logging reason with a

+- Removed the unreachable first-sentence fallback branch because the notification
+  body regex always matches the start of the message.

+
+## Phase 3 Coverage Checkpoint: Web Swipe Gesture Offset And Missing Handler Paths
+
+Updated `src/__tests__/web/hooks/useSwipeGestures.test.ts`.
+
+Behavior covered:
+
+- Added coverage for tracked movement before the direction-lock threshold is
+  reached, verifying offsets remain unchanged until a direction is locked.
+- Added coverage for a valid vertical swipe with no matching callback, verifying
+  the hook does not invoke the wrong vertical handler.

+
+Updated `src/renderer/services/wizardIntentParser.ts` and

+- Executed the removed-worktree-paths updater callback to verify it preserves
+  existing tracked paths while adding deleted worktree paths.
+- Added session rename sync coverage for missing `toolType` fallback to Claude
+  storage.
+- Added rejected provider-name-sync coverage for both Claude and non-Claude

+## Phase 3 Coverage Checkpoint: Offline Queue Retry And Resume Branches
+
+Updated `src/web/hooks/useOfflineQueue.ts` and

+- Added thrown-command retry coverage for commands that still have attempts

+- Added in-flight resume coverage, verifying a resume call during active
+  processing does not start a second processor or leave the hook paused.
+- Removed the mid-loop `isOnline` / `isConnected` recheck because those booleans
+  are captured for the active `processQueue` callback; initial connectivity is
+  already guarded before processing starts, and per-command connection loss is
+  represented by `sendCommand` returning `false` or throwing.

+- The full coverage aggregate statement/function/line covered counts shifted
+  slightly downward in this run while the targeted file reached 100%; the branch
+  count increased and the suite passed. Treat the full artifact, not memory of a
+  prior run, as the current baseline.
+- No coverage exclusion was made in this checkpoint.
+
+## Phase 3 Coverage Checkpoint: Activity Bus Listener Lifecycle
+
+Added `src/__tests__/renderer/utils/activityBus.test.ts`.
+
+Behavior covered:
+
+- First subscriber lazily attaches the five passive global activity listeners and
+  receives dispatched activity events.
+- Duplicate subscription of the same callback does not attach duplicate window
+  listeners and only invokes the Set-backed callback once per event.
+- Multiple distinct subscribers share the same listener set; removing one
+  subscriber keeps listeners attached and removing the last subscriber detaches
+  them.
+- Repeated unsubscribe cleanup exercises the defensive detach guard without
+  removing listeners twice.

+
+## Phase 3 Coverage Checkpoint: Live Overlay Tunnel Error And Reset Paths
+
+Added `src/__tests__/renderer/hooks/useLiveOverlay.test.ts`.

+- Copy flash messages set visible feedback, auto-clear after two seconds, and can
+  be explicitly cleared with `null`.
+- The click-outside callback registered by `useClickOutside` closes the live
+  overlay.
+- Tunnel start failures cover missing-error default messages, thrown `Error`
+  messages, and thrown non-`Error` fallback messages.
+- Toggling from an error state is a no-op and does not start or stop the tunnel
+  again.
+- Stop failures are logged but still clear connected tunnel state and switch the
+  active tab back to local.
+- Disabling live mode resets tunnel status, URL, error, and active tab state.

+- Stopping coverage now includes default-state initialization and aborting from
+  `PAUSED_ERROR` while clearing the stored error details.
+- Completion coverage now includes existing `COMPLETING`, `STOPPING`, and
+  missing-session finalization paths, including session ID preservation and

+## Phase 3 Coverage Checkpoint: Wizard Prompt Continuation And Fallback Parsing
+
+Updated `src/__tests__/renderer/components/Wizard/services/wizardPrompts.test.ts`.

+  system prompt.
+- Structured-output parsing now covers parsed JSON `null` as invalid structured
+  output rather than a valid response object.
+- Fallback confidence extraction now covers out-of-range values and preserves

+- Covered template-variable expansion that writes expanded document content back
+  before spawning the agent.
+- Covered cwd override selection, agent session origin registration, and
+  registration failure logging.
+- Covered successful response synopsis extraction for sentence, no-sentence,
+  long-truncation, blank, cleaned-empty, and too-short response cases.
+- Covered failed task synopsis behavior with and without an agent response.

+  behavior without depending on canvas or graph layout internals.
+- Covered successful graph loading, file watcher registration, cached external
+  link toggling, selected document stats and markdown task counts, in-graph
+  markdown preview loading with generated file tree data, preview link
+  navigation, load-more pagination, and graph load error retry.
+- Verified SSH remote IDs flow through graph loading and preview file reads.

+
+Extended `src/__tests__/renderer/hooks/useTabHandlers.test.ts` for

+
+Coverage-focused changes:
+
+- Covered stale active file-tab IDs returning `null` derived state.
+- Covered replacing the active file preview tab with `openInNewTab: false`,
+  including extension-less filenames, forward-history truncation, current-file
+  history insertion, remote ID preservation, and no-duplicate current history.
+- Covered opening new file tabs adjacent to the active file tab, and fallback
+  append behavior when the active file tab is absent from `unifiedTabOrder`.
+- Covered missing active-session and missing file-tab close no-op behavior.
+- Covered edit-mode, edit-content, search-query, and scroll-position updates
+  preserving inactive sessions and non-target file tabs, including updating the
+  current navigation-history scroll entry.

+- Covered file-tree/cwd plugin wiring by asserting the `remarkFileLinks` plugin
+  receives prebuilt file-tree indices and the current working directory.

+## Phase 3 Coverage Checkpoint: GitWorktreeSection UI Branches
+
+Added `src/__tests__/renderer/components/GitWorktreeSection.test.tsx` for

+
+Coverage-focused changes:
+
+- Covered GitHub CLI unavailable, loading, authenticated, and unauthenticated
+  states, including disabled toggles and the external GitHub CLI link.
+- Covered local worktree enablement, base directory editing, folder browsing,
+  branch-name editing, computed path display, PR creation toggling, target
+  branch selection, empty branch lists, and outside-click dropdown closing.
+- Covered SSH remote browse suppression and worktree validation states for
+  checking, existing same-branch worktrees, branch mismatch, uncommitted-change
+  blockers, and different-repository errors.

+100.00% branch coverage, including `process.ts`, `marketplace.ts`, `git.ts`, and
+`groupChat.ts`.
+
+Coverage-focused changes:
+
+- Added active session-based tests without touching the pre-existing skipped
+  legacy agent-selection describes.
+- Covered closed-modal behavior, source-session and terminal-session filtering,
+  fallback target session names from `projectRoot`, and the `Unnamed Session`
+  fallback.
+- Covered search filtering by session name and project path, multi-result
+  sorting, no-match state, and no-target-session empty state.
+- Covered source-tab display fallbacks for missing tabs, `agentSessionId`
+  prefixes, unnamed new tabs, and log entries with missing text.
+- Covered target selection, preview target rows, clean-context toggling,
+  successful send payloads, failed sends, in-flight sending UI, layer-stack
+  Escape close behavior, Enter selection/send behavior, arrow navigation, numeric
+  quick selection, Space selection, and tenth-option quick-select label omission.

+
+Added `src/__tests__/renderer/components/CollapsibleJsonViewer.test.tsx` for

+
+Coverage-focused changes:
+
+- Covered primitive rendering with key punctuation and theme colors for strings,
+  numbers, booleans, `null`, and `undefined`.
+- Covered long-string escaping and truncation, compact object previews, larger
+  object previews, array previews, empty object/array rendering, and root
+  primitive rendering.
+- Covered expandable object and array toggling, child rendering, and collapsed
+  preview restoration.
+- Covered non-JSON primitive stringification through a function value.
+- Covered copy-button behavior for string values, object JSON formatting, event
+  propagation suppression, and clipboard-write failure without success feedback.

+  exercise network failure behavior through an actual server. Real websocket,

+## Phase 7 Coverage Checkpoint: Auto-Updater Events And IPC
+
+Coverage-focused changes:
+
+- Added `src/__tests__/main/auto-updater.test.ts` for the Electron
+  auto-updater orchestration module.
+- Added a minimal `_setAutoUpdaterLoaderForTesting` loader seam in
+  `src/main/auto-updater.ts` so tests can inject an updater without loading
+  Electron at module runtime. Runtime behavior still uses the default lazy
+  `require('electron-updater')` loader.
+- Covered lazy updater initialization defaults, event registration, IPC handler
+  registration idempotence, renderer status delivery, unavailable web contents,
+  update-available/not-available/progress/downloaded/error events, update-check
+  IPC success/no-update/error paths, download success/no-update/error paths,
+  install IPC, status IPC, manual checks, prerelease toggling, non-`Error`
+  catch fallbacks, and the default CommonJS loader path.

+Coverage-focused changes:

+- Covered the exported emoji-aware name helpers, group ordering, session
+  ordering within groups, ungrouped ordering, worktree child sorting under

+  bookmark ordering, intentional bookmarked duplicates in visible sessions,
+  bookmark-folder collapse behavior, collapsed group visibility, missing group
+  visibility, worktree children excluded from jump shortcuts, and empty inputs.
+- Simplified `useSortedSessions.ts` so grouped/ungrouped callers rely on the
+  existing `addSessionWithWorktrees` child guard instead of pre-filtering
+  worktree children twice. This keeps output behavior unchanged while making the
+  defensive child-skip path directly exercised by tests.

+- Covered non-Linux cache behavior, Microsoft and generic WSL proc-version
+  detection, non-WSL Linux proc versions, missing `/proc/version`, read
+  failures, Windows mount path matching and non-matches, warning behavior for
+  WSL Windows mount paths, debug behavior for WSL Linux filesystem paths, and
+  the user-facing WSL warning message.

+
+Coverage-focused changes:
+
+- Added `src/__tests__/renderer/components/Wizard/tour/TourOverlay.test.tsx`

+- Fixed tour analytics behavior so explicit skip paths report
+  `onTourSkip`/`onClose` without also reporting `onTourComplete`, and keyboard
+  Enter on the final step now follows the completion path instead of the skip
+  path.
+- Removed a redundant keydown `isOpen` guard because the handler is only
+  registered while the overlay is open.
+- Covered closed rendering, open-session start analytics, StrictMode start
+  deduping, layer-stack registration/unregistration, welcome start and skip
+  controls, keyboard navigation from welcome and active steps, skip analytics
+  for button and Escape paths, final-step keyboard completion, completion
+  without optional analytics callbacks, active-step prop forwarding, spotlight
+  clip-path/ring styles with explicit and default padding/radius, and null-step
+  rendering after leaving the welcome screen.

+- Covered provider forwarding of sessions, polling options, and
+  `activeSessionId`; focused branch/file/detail context values; legacy
+  `useGitStatus` compatibility values; missing-session fallbacks; refresh
+  delegation through detail and legacy contexts; default provider options; empty
+  status maps; and provider-required error paths for all four consumer hooks.
+- Locally suppressed expected React error output for provider-required hook
+  assertions so the test does not add stack-trace noise.

+Coverage-focused changes:

+- Added `src/__tests__/renderer/components/GroupChatModals.test.tsx` for

+  current-name initialization, close/reopen reset with a new current name,
+  rename cancel, blank and unchanged-name disabled/guard behavior, trimmed
+  rename submission, and Enter-key rename submission.
+- The test was changed to mock the shared `Modal`, `ModalFooter`, and
+  `FormInput` shells directly instead of mocking the layer-stack context, to
+  keep this checkpoint scoped to group-chat modal behavior and avoid influencing
+  layer-context coverage in neighboring files.

+- The full-suite aggregate for this checkpoint is lower than the prior recorded
+  checkpoint despite both targeted modal files moving from 0% to 100%. The full
+  coverage command was rerun after isolating the shared UI shell and stabilized
+  at the current values above. No coverage exclusions were added or widened; the
+  current values are the baseline for the next checkpoint.
+
+Remaining risk:
+
+- These tests mock the shared modal/input shell to isolate the delete and rename
+  modal contracts. Generic modal focus, layer-stack, and form-input behavior
+  remain covered by their shared component and hook suites.
+- Store-level delete/rename effects and persistence are covered by group-chat
+  handler/store tests rather than these confirmation modals.
+- No exclusions were added or widened.

+- Covered closed rendering, moderator-only empty state, resize-handle wiring,
+  collapse callback/shortcut title, resizable-panel configuration, participant
+  color-map inputs, moderator metadata and usage propagation, alphabetical
+  participant ordering, participant state fallback, live-output lookup, context
+  reset success, expected reset failure logging, and participant removal IPC
+  wiring.
+- Mocked `ParticipantCard`, `useResizablePanel`, `useGroupChatStore`, and

+  orchestration contract without duplicating already-covered child-card and color
+  utility behavior.

+- Covered completed-playbook heading and summary copy, plural and singular task

+  covered by `src/__tests__/renderer/utils/confetti.test.ts`.

+
+## Phase 6 Coverage Checkpoint: Shared Agent Selector
+
+Coverage-focused changes:
+
+- Added `src/__tests__/renderer/components/shared/AgentSelector.test.tsx` for
+  `src/renderer/components/shared/AgentSelector.tsx`.
+- Covered loading state, default and custom empty states, filter behavior,
+  available and unavailable agent status, selected-card styling, command/path
+  display fallback, beta badges, refresh handling with propagation isolation,
+  refreshing spinner state, expanded content rendering, supported-agent gating,
+  compact mode, disabled unsupported-card behavior, and the unsupported
+  no-coming-soon branch.
+- Added a local `console.error` spy only around the existing nested refresh
+  button warning and asserted the warning, keeping the focused suite quiet
+  without globally suppressing unexpected errors.

+  output, stderr failures, and fallback/generic error messages for read, stat,
+  size, write, exists, mkdir, rename, delete, and count operations.
+- Replaced two structurally unreachable branches in `remote-fs.ts`: a
+  post-loop SSH retry fallback after all reachable loop paths already return,

+## Phase 5 Coverage Checkpoint: Factory Droid Session Storage Follow-Up
+
+Coverage-focused changes:
+
+- Expanded `src/__tests__/main/storage/factory-droid-session-storage.test.ts`
+  for `src/main/storage/factory-droid-session-storage.ts`.
+- Covered local listing where an assistant message and an empty user message
+  appear before the first usable user prompt, proving the session preview skips
+  non-user and empty content before selecting the first non-empty user text.
+- Reworked Factory Droid text extraction to collect text parts explicitly
+  instead of mapping `c.text || ''` after a truthy `c.text` filter. This keeps
+  behavior unchanged while removing an unreachable defensive fallback branch.

+- Covered SQLite sessions whose preview candidate messages have no part rows,
+  proving that listing falls back to the SQLite title instead of fabricating
+  message text.
+- Added a minimal behavior-preserving part lookup seam in
+  `src/main/storage/opencode-session-storage.ts` and reused it across local,
+  remote, search, read, and delete paths. This removed repeated unreachable
+  `parts.get(id) || []` fallback branches where local/remote loaders already
+  guarantee an entry per loaded message.
+- Reworked OpenCode text extraction to collect text parts explicitly instead
+  of mapping `p.text || ''` after a truthy `p.text` filter.
+- Removed the unused private `existingDb` branch from SQLite message loading;
+  the method is only called without an existing handle and still closes its own
+  DB handle in `finally`.

+Coverage-focused changes:

+- Covered local and remote sessions with missing `cwd`, unrecognized metadata

+  deletion cleanup that preserves unrelated tool results.
+- Removed unreachable fallback branches in

+  non-positive input timeouts, GH CLI install/path/auth cache behavior, GH
+  status TTL expiry, SSH path detection/cache behavior, Windows built-in
+  OpenSSH fallback, fallback errors, and async SSH path resolution.
+- Simplified three unreachable defensive path fallbacks in

+
+- Context grooming now has focused coverage for process-manager event ordering,

+  groomed context.
+- Full-suite output remains noisy outside this touched area, including expected

+  `lucide-react` mock warning for `Briefcase`, a `--localstorage-file` warning,
+  a duplicate `vs` key warning, stale Browserslist data, and expected error

+
+Coverage-focused changes:

+  export refresh behavior, successful probes with no stdout stream, stderr and
+  no-stderr non-zero shell exits, spawn errors with retry after cache cleanup,
+  timeout kill behavior, and ignored kill failures during timeout cleanup.

+- Mocked `useAgentConfiguration`, `AgentConfigPanel`, `SshRemoteSelector`, and

+  modal's command filtering, rendered labels, callback contracts, async debug
+  package flow, and Electron shell/devtools/debug/leaderboard API calls are
+  exercised through the existing test harness.

+- Added browser-like markdown search coverage for the CSS Custom Highlight API,
+  including highlight registration, current-match updates, next-match
+  navigation, scroll coordination, and cleanup on unmount.
+- The tests use local shims for `CSS.highlights`, `window.Highlight`,

+  from the Auto Run folder with SSH context, inline data URL images, remote URL
+  images, invalid absolute-path image data, and rejected relative image reads.
+- The tests assert the filesystem read paths, SSH remote propagation, loading

+
+Coverage-focused changes:

+- Added behavior coverage for trimmed sending, staged image payloads,
+  read-only send mode, busy-state queue sending, Cmd/Ctrl+R read-only toggling,
+  Cmd/Ctrl+Y staged-image lightbox opening, Cmd/Ctrl+Enter behavior, plain
+  Enter-to-send behavior, Shift+Enter non-send behavior, prompt composer launch,
+  Enter-to-send toolbar toggling, external draft synchronization, group-chat
+  draft reset, trimmed text paste insertion, image paste/drop delegation, file
+  input validation, selected image preview creation, duplicate/invalid/oversize
+  image handling, staged image lightbox/remove behavior, and queued message
+  rendering/removal.
+- Kept the existing mention-autocomplete tests intact and extended coverage
+  around the adjacent input controls instead of asserting implementation-only
+  state.

+- Covered hidden and generating states, Austin fact typing and link handling,
+  external-link invocation and fallback, raw streaming preview, markdown
+  preview toggling, incomplete code-block and incomplete markdown-link cleanup,
+  resume auto-scroll, filename reset behavior, cancel actions, elapsed time
+  display, generated document totals, per-document expansion, checklist-only
+  document descriptions, previous auto-expanded file collapse, and exit actions.
+- Fixed `DocumentGenerationView.tsx` to capture the previous auto-expanded file
+  before scheduling the expansion state update, so adding a new generated
+  document collapses the prior auto-expanded entry as intended.
+- Mocked the Austin facts service and lucide icons only at the display boundary.

+
+## Phase 6 Coverage Checkpoint: Wizard Existing Docs Modals
+
+Coverage-focused changes:
+
+- Added `src/__tests__/renderer/components/Wizard/ExistingDocsModals.test.tsx`
+  for the previously zero-coverage Wizard existing-document choice modals:
+  `ExistingAutoRunDocsModal.tsx` and `ExistingDocsModal.tsx`.
+- Covered existing Auto Run document detection copy, project folder display,
+  plural and singular document counts, safer default focus on continue actions,
+  keyboard continue/start-fresh selection, focused start-fresh styling,
+  LayerStack Escape cancellation, continue and cancel callbacks, successful
+  existing-doc deletion before starting fresh, delete-result failures, thrown
+  non-`Error` failures, expected console error assertions, disabled deleting
+  state, and modal key propagation behavior.
+- Mocked only lucide icons and the `window.maestro.autorun.deleteFolder` bridge.
+  No production code or coverage exclusions were changed.

+  files: `src/renderer/slashCommands.ts`, `src/renderer/wdyr.dev.ts`,
+  `src/renderer/components/GroupChatPanel.tsx`, and `src/shared/stats-types.ts`.
+- Covered built-in slash command metadata and visibility rules, the stats schema
+  version constant, why-did-you-render development profiler configuration, and
+  `GroupChatPanel` composition/passthrough of header, messages, and input props.
+- Used a `forwardRef`-compatible mock for `GroupChatMessages` to avoid adding

+
+Coverage-focused changes:

+- Added `src/__tests__/main/index.test.ts` for `src/main/index.ts`, removing

+- Covered main bootstrap wiring for app readiness, single-instance locking,
+  IPC/lifecycle dependency registration, CLI watcher startup, window creation,
+  group-chat routing, process-manager wiring, provider storage construction,
+  WakaTime/stat/history startup calls, settings watchers, process signal
+  handlers, and shutdown cleanup.
+- Exercised registered dependency getter callbacks and lifecycle closures
+  through mocked Electron and service modules instead of importing the real app
+  environment.
+- Extended the harness across demo data, development data isolation,
+  `USE_PROD_DATA`, WakaTime startup and enablement, Sentry event filtering and
+  initialization failure handling, history/stats startup failure logging, and
+  macOS menu registration.
+- Added local assertions for expected startup `console.log` messages so the
+  entrypoint-focused test stays quiet without silencing logs outside this suite.
+- Cleaned a recurring UsageDashboard test-output warning by adding missing
+  `Briefcase` and `Coffee` exports to the local `lucide-react` mocks in the
+  responsive-layout and state-transition test files.

+## Phase 6 Coverage Checkpoint: Renderer App Shell
+
+Coverage-focused changes:
+
+- Added `src/__tests__/renderer/App.test.tsx` for the real `src/renderer/App.tsx`
+  shell, removing the last zero-statement production file from the coverage
+  report.
+- Rendered the app with the same provider envelope used by production
+  (`LayerStackProvider`, `WizardProvider`, and the app's own providers), rather
+  than using an import-only test.
+- Covered the no-session startup shell: empty-state rendering, splash hiding,
+  GitHub CLI status check, group-chat bridge subscriptions, stats database
+  initialization-result check, and explicit cleanup of the batch processor
+  unmount log.
+- Covered the active-session workspace shell with a busy AI tab: title
+  composition, process listener registration, history external-change
+  subscription, session restoration through the preload bridge, and cleanup.
+- Covered App-level lazy orchestration for settings, marketplace, symphony, and
+  director-notes modals plus the document graph mount path. The lazy modules are
+  mocked only in this App shell test; their behavior remains covered by their
+  component-specific suites.
+- Filled only test-local preload bridge gaps needed by the mounted hooks
+  (`power`, `updates`, `groupChat`, `history`, prompt registries, worktree
+  discovery, remote process listeners). No production code or coverage
+  exclusions were changed.

+  activation, queue removal, toast navigation, document graph read/failure

+
+Coverage-focused changes:
+
+- Expanded `src/__tests__/renderer/components/SymphonyModal.test.tsx` with

+  `AgentCreationDialog`.
+- Verified successful agent creation calls the Symphony start hook with the
+  selected repo, issue, agent type, generated session placeholder, and working
+  directory, then reports the contribution metadata back through
+  `onStartContribution`.
+- Covered closing the agent creation dialog without starting a contribution.
+- Covered in-progress issues that are already claimed by a draft PR, including
+  opening the claimed PR link without selecting the parent issue card.
+- Covered failed external document preview responses, thrown document-preview
+  IPC failures with local `console.error` assertions, and keyboard document
+  navigation invoking the preview path.
+- Kept the test at the component boundary with mocked Symphony hooks; the hook
+  suites remain the source of truth for registry/state/IPC behavior.

+  loading/error/empty states, tab keyboard cycling, top-level Escape handling,
+  category/search filtering, alternate active-contribution status labels, and
+  remaining pre-flight cancel paths.
+- The component test intentionally mocks `useSymphony`, `useContributorStats`,

+  hook IPC implementation or full agent configuration dialog behavior.
+- The global `Meta/Ctrl+Shift+[` and `Meta/Ctrl+Shift+]` tab cycling shortcut

+  preview read failures, document/external node context-menu routing, and file
+  watcher start/stop failures.
+- Extended the local `MindMap` mock so the parent view can exercise double-click,
+  open-file, and context-menu callbacks without depending on canvas behavior.
+- Cleaned expected-error output in the touched DocumentGraph area by asserting
+  the `Failed to build graph data` error locally.
+- Updated `src/__tests__/renderer/components/DocumentGraph/graphDataBuilder.test.ts`
+  to assert the expected parse-warning path instead of printing it during the
+  DocumentGraph group run.

+
+Coverage-focused changes:

+  passed: 5 files, 485 tests passed, 6 skipped. The run still emits
+  pre-existing React `act(...)` warnings from the Auto Run hook tests.
+- `npm run test:coverage -- --silent` passed: 665 files passed, 1 skipped;
+  25,234 tests passed, 107 skipped. The project-wide totals and target file
+  coverage above came from this run.
+
+Remaining risk:
+
+- `AutoRun.tsx` still has uncovered branches around image-cache double-check
+  timing, stale image-load cleanup, edit-mode staged-image interactions, task
+  parsing variants, search navigation boundaries, document selection fallback
+  states, and selected lightbox paths.
+- These tests prove cache and filesystem resolution behavior in JSDOM; they do
+  not verify browser image layout, pointer hover overlay quality, or Electron
+  viewport behavior.
+- The related Auto Run hook run remains noisy due to pre-existing React
+  `act(...)` warnings from asynchronous image state updates. This checkpoint did
+  not add global suppression.
+- No exclusions were added or widened.
+
+## Phase 3/6 Coverage Checkpoint: Merge Session Hook Orchestration
+
+Coverage-focused changes:
+
+- Added `src/__tests__/renderer/hooks/agent/useMergeSession.test.tsx` for
+  `src/renderer/hooks/agent/useMergeSession.ts`.
+- Covered active-tab merge state selectors plus `clearTabState`, `cancelTab`,
+  `cancelMerge`, `reset`, and the exported test reset utility for the global
+  merge flag.
+- Covered recoverable validation failures for concurrent merges, duplicate
+  source-tab merges, missing source tabs, missing target tabs, self-merges, and
+  empty source contexts.
+- Covered raw merge success paths for new sessions and existing target tabs,
+  including timestamp sorting, unsorted merge ordering, empty-target
+  informational logging, large-context warnings, completion state, and target
+  metadata in the returned result.
+- Covered AI grooming success, progress callbacks, token-saved messaging,
+  grooming failure fallback, and cancellation while grooming is in progress.
+- Covered `useMergeSessionWithSessions` wrapper behavior for missing target
+  sessions, adding newly created merged sessions, non-fatal history logging
+  failures, `onSessionCreated`, injecting source-only context into existing
+  target tabs, preserving non-target tabs, and `onMergeComplete`.

+Remaining risk:

+- The remaining uncovered statements in `useMergeSession.ts` are cancellation
+  timing windows after validation, after context extraction, and after raw merge

+  or intentionally brittle object/proxy tricks to force mid-stack cancellation.
+- The grooming service and history bridge are mocked. These tests prove hook
+  orchestration and state updates, not the external AI grooming implementation
+  or Electron history persistence.
+- The modal/UI workflow that triggers these hooks remains covered separately by
+  component and transfer-handler tests; this checkpoint does not add E2E
+  coverage for a user-driven merge operation.
+- No exclusions were added or widened.

+
+Coverage-focused changes:
+
+- Expanded `src/__tests__/main/group-chat/group-chat-router.test.ts` for

+- Covered the participant response timeout path for normal moderator
+  `@mention` handoffs, including the system timeout message, participant state
+  reset, pending-participant cleanup, timeout log entry, and moderator
+  synthesis spawn after the last pending participant is force-completed.
+- Covered the Auto Run timeout path for `!autorun` participants, including
+  renderer batch-completion emission, participant state reset, and pending
+  cleanup.
+- Added a local polling helper for the timeout tests so assertions wait for the
+  timeout callback's asynchronous file-log write before checking downstream
+  state.

+Coverage-focused changes:

+- Added asserted coverage for first-run celebration payloads, standing ovation
+  badge/record payloads, leaderboard submit payloads, missing-auth-token
+  warnings, rejected leaderboard submissions, server-total sync, group-chat
+  Auto Run completion success/failure reporting, Symphony auto-finalization
+  success/manual/failure paths, PR group fallback behavior, queue fallback when
+  a queued target tab is missing, and the quit-confirmation no-bridge guard.
+- Mocked the direct notification and Sentry side-effect modules in this test
+  file so user-visible notifications and captured failures can be asserted
+  instead of only executing silently.
+- Cleaned the focused hook test signal by keeping the asynchronous leaderboard
+  store update inside React `act`.

+
+Remaining risk:
+
+- `GroupChatList.tsx` still has a tiny uncovered branch around one context-menu
+  action/guard path. The covered behavior now includes the primary user-visible
+  group-chat list workflows.
+- These are jsdom component tests with mocked context-menu positioning. They
+  prove renderer behavior and callbacks, not full sidebar integration with
+  `SessionList` or persisted group-chat storage.
+- No exclusions were added or widened.

+## Phase 6 Coverage Checkpoint: New Instance Modal Config Carryover
+
+Coverage-focused changes:
+
+- Expanded `src/__tests__/renderer/components/NewInstanceModal.test.tsx` for
+  `src/renderer/components/NewInstanceModal.tsx`.
+- Added duplicate-session create coverage that verifies source session nudge,
+  custom path, custom args, custom environment variables, custom model, custom
+  context window, and custom provider path are passed through to `onCreate`.
+- Added saved per-agent config coverage that verifies persisted custom path,
+  arguments, and environment variables are preloaded into the agent config panel
+  and included in the create payload.

+## Phase 3 Coverage Checkpoint: Batch Time Tracking Hook
+
+Coverage-focused changes:
+
+- Added `src/__tests__/renderer/hooks/batch/useTimeTracking.test.ts` for
+  `src/renderer/hooks/batch/useTimeTracking.ts`.
+- Covered visible elapsed-time tracking, final elapsed-time calculation, cleanup
+  of stopped sessions, hidden-document start behavior, hidden pause accumulation,
+  visible resume behavior, callback updates for paused/resumed sessions, missing
+  session fallbacks, absent callback behavior, visibility listener cleanup, and

+- No exclusions were added or widened.
+
+## Phase 3 Coverage Checkpoint: Austin Facts Service
+
+Coverage-focused changes:
+
+- Added `src/__tests__/renderer/components/Wizard/services/austinFacts.test.ts`
+  for `src/renderer/components/Wizard/services/austinFacts.ts`.
+- Covered shuffled fact queue exhaustion and reset behavior, exported fact list

+- No exclusions were added or widened.
+
+## Phase 3 Coverage Checkpoint: Group Chat Store Live Output
+
+Coverage-focused changes:
+
+- Extended `src/__tests__/renderer/stores/groupChatStore.test.ts` for
+  `src/renderer/stores/groupChatStore.ts`.
+- Covered participant live-output append behavior for new and existing

+
+Remaining risk:

+- `groupChatStore.ts` is now fully covered at the store-contract level,
+  including state setters, Map-backed state, live output buffering, reset
+  behavior, and non-React accessors. This checkpoint does not prove every group
+  chat UI consumer renders live output correctly; those paths remain covered by
+  component and integration tests.
+- No exclusions were added or widened.
+
+## Phase 7 Coverage Checkpoint: Static Web Server Routes
+
+Coverage-focused changes:
+
+- Extended `src/__tests__/main/web-server/routes/staticRoutes.test.ts` for

+- Covered cached manifest and service-worker success paths, cached missing-file
+  lookups, read failures for cached files, missing and unreadable `index.html`

+
+Remaining risk:

+- `staticRoutes.ts` is now fully covered for route registration, token
+  redirects, PWA asset serving and caching, dashboard HTML serving, asset-path
+  rewriting, sanitized session config injection, and recoverable filesystem
+  failures. Broader websocket and API route behavior remains covered by the
+  separate web-server route and service tests.
+- No exclusions were added or widened.
+
+## Phase 7 Coverage Checkpoint: Web App Shell
+
+Coverage-focused changes:
+
+- Added `src/__tests__/web/App.lazy-fallback.test.tsx`.
+- Extended `src/__tests__/web/App.render.test.tsx` and
+  `src/__tests__/web/App.test.tsx` for `src/web/App.tsx`.
+- Covered dashboard and session mode context construction, `tabId` URL
+  encoding, no-op URL updates, history replacement for changed session URLs,
+  service-worker success/update/offline callbacks, offline context propagation,
+  desktop theme propagation, `AppRoot`, default hook values outside providers,

+Target-file movement:
+
+- `src/web/App.tsx` moved from remaining missed lazy-fallback statements,
+  default context callback functions, and placeholder rendering paths to full
+  coverage across all four metrics.
+- No production testability seam was required; the fallback path is exercised by
+  a test-local mocked dynamic import failure.
+
+Validation:

+- `npm run test:coverage -- --silent` passed: 677 files passed, 1 skipped;
+  25,365 tests passed, 107 skipped. The project-wide totals and target file
+  coverage above came from this run.
+
+Remaining risk:
+
+- `App.tsx` is now fully covered for shell-level behavior, provider wiring,
+  service-worker status handling, theme updates, navigation helpers, and
+  recoverable chunk-load failure. It does not prove behavior inside the mobile
+  remote-control interface itself; `src/web/mobile/App.tsx` and related mobile
+  views still need separate coverage.
+- The full suite still emits known noisy expected-error output from existing
+  error-boundary and context misuse tests, plus existing Browserslist and
+  duplicate-key warnings. These are not introduced by this checkpoint, but they
+  remain Phase 2 test-signal cleanup work.
+- No exclusions were added or widened.
+
+## Phase 6 Coverage Checkpoint: History Lookback Selector
+
+Coverage-focused changes:
+
+- Added `src/__tests__/renderer/components/History/LookbackSelector.test.tsx`
+  for `src/renderer/components/History/LookbackSelector.tsx`.
+- Covered rendering of the selected lookback label, slider value mapping,
+  gradient fill calculation, callback payloads for predefined options including
+  "All time", fallback behavior for unknown lookback values, disabled state and
+  dimmed styling, and the defensive guard for an unresolved option lookup.
+

+
+Target-file movement:
+
+- `LookbackSelector.tsx` moved from an unrendered control with uncovered
+  callbacks and branches to full coverage across all four metrics.
+- The test-local `LOOKBACK_OPTIONS` mutation is restored in a `finally` block
+  and is limited to proving the component's existing defensive guard. DOM range
+  inputs clamp out-of-range values, so a normal out-of-range slider event would
+  incorrectly exercise the valid "All time" option instead of the guard.
+
+Validation:
+
+- `npm run test -- src/__tests__/renderer/components/History/LookbackSelector.test.tsx --run`
+  passed: 1 file, 4 tests passed.
+- `npm run test:coverage -- --silent` passed: 678 files passed, 1 skipped;
+  25,369 tests passed, 107 skipped. The project-wide totals and target file
+  coverage above came from this run.
+
+Remaining risk:
+
+- `LookbackSelector.tsx` is now fully covered for its local rendering and
+  interaction contract. It does not prove the larger history panel applies the
+  selected lookback to data fetching or aggregation; those workflows remain
+  covered by the broader history component tests.
+- No exclusions were added or widened.
+
+## Phase 6 Coverage Checkpoint: Inline Wizard Exit Confirmation Dialog
+
+Coverage-focused changes:
+
+- Extended
+  `src/__tests__/renderer/components/InlineWizard/WizardExitConfirmDialog.test.tsx`
+  for
+  `src/renderer/components/InlineWizard/WizardExitConfirmDialog.tsx`.
+- Covered the no-layer-id lifecycle path, updated escape handler behavior when
+  `onCancel` changes, natural handling for `Tab` and `Enter`, and propagation
+  blocking for other keys.
+
+Coverage after this checkpoint:

+Target-file movement:
+
+- `WizardExitConfirmDialog.tsx` moved from 6 missed statements, 6 missed branch

+- The added tests assert layer-stack registration failure handling and keyboard
+  propagation behavior without changing production dialog code.

+- `WizardExitConfirmDialog.tsx` is now fully covered for its rendering, focus
+  default, layer-stack lifecycle, escape-handler refresh, button callbacks,

+  exit flow remains covered by higher-level wizard tests.
+- No exclusions were added or widened.

+## Phase 6 Coverage Checkpoint: Wizard Exit Confirmation Modal
+
+Coverage-focused changes:
+
+- Added

+  for `src/renderer/components/Wizard/WizardExitConfirmModal.tsx`.
+- Covered prompt rendering, step-progress calculation, focus behavior, confirm,

+Target-file movement:
+
+- `WizardExitConfirmModal.tsx` moved from missed layer-stack and keyboard
+  handler branches to full coverage across all four metrics.
+- The added tests keep the layer-stack mock local to the component contract and
+  do not change production modal behavior.
+
+Validation:
+
+- `npm run test -- src/__tests__/renderer/components/Wizard/WizardExitConfirmModal.test.tsx --run`
+  passed: 1 file, 7 tests passed.
+- `npm run test:coverage -- --silent` passed. The project-wide totals and
+  target file coverage above came from this run.

+Remaining risk:
+
+- `WizardExitConfirmModal.tsx` is now fully covered for its local rendering,
+  progress display, focus default, layer-stack lifecycle, escape-handler
+  refresh, button callbacks, keyboard filtering, and accessibility attributes.
+  The broader wizard exit workflow remains covered by higher-level wizard tests.
+- No exclusions were added or widened.
+
+## Phase 3 Coverage Checkpoint: Agent Error Recovery Hook
+
+Coverage-focused changes:
+
+- Extended `src/__tests__/renderer/hooks/useAgentErrorRecovery.test.ts` for
+  `src/renderer/hooks/agent/useAgentErrorRecovery.tsx`.
+- Covered the recovery action decision table for Claude and non-Claude
+  authentication errors, token exhaustion, rate limits, network errors, agent
+  crashes, permission denials, unhandled/default error types, missing optional
+  callbacks, no-current-error state, `handleRecovery` execution and no-op
+  behavior, and `clearError` with and without a callback.

+- `useAgentErrorRecovery.tsx` moved from 64.29% statements, 40.54% branches,
+  50.00% functions, and 66.67% lines to full coverage across all four metrics.
+- The added tests assert user-facing action labels, descriptions, primary-action
+  selection, callback execution, and no-op behavior for unavailable actions
+  rather than only checking that actions exist.
+
+Validation:
+
+- `npm run test -- src/__tests__/renderer/hooks/useAgentErrorRecovery.test.ts --run`

+- `npm run test:coverage -- --silent` passed: 679 files passed, 1 skipped;

+  coverage above came from this run.
+
+Remaining risk:
+
+- `useAgentErrorRecovery.tsx` is now fully covered for its local recovery
+  decision contract and handler behavior. It does not prove the higher-level
+  modal and group-chat consumers display every recovery action correctly; those
+  remain covered by their own component and hook tests.
+- No exclusions were added or widened.
+
+## Phase 3 Coverage Checkpoint: Session Viewer Hook
+
+Coverage-focused changes:
+
+- Added `src/__tests__/renderer/hooks/useSessionViewer.test.ts` for
+  `src/renderer/hooks/agent/useSessionViewer.ts`.
+- Covered initial message loading, agent/SSH IPC read parameters, loading state
+  reset, initial scroll-to-bottom and focus behavior, older-message pagination,
+  view-session state reset, explicit load-more, scroll-triggered lazy loading
+  with scroll-position preservation, no-op guards for missing `cwd`, absent
+  container, and non-threshold scroll positions, failed read logging, and
+  clearing the detail view.
+- Removed an unreachable inner `if (container)` inside the scroll-preservation
+  animation frame. The callback captures `container` only after the hook has
+  already returned for a missing container, so the false path was not reachable
+  through runtime behavior.

+
+Target-file movement:
+
+- `useSessionViewer.ts` moved from 11 missed statements, 11 missed branch paths,
+  and 2 missed functions to full coverage across all four metrics.
+- The production change reduced the target-file statement, branch, and line
+  denominator by removing an unreachable defensive branch. No coverage
+  exclusions were added or widened.

+
+Remaining risk:
+
+- `useSessionViewer.ts` is now fully covered for its local session-detail state,
+  pagination, IPC read parameters, scroll behavior, and recoverable read
+  failures. It does not prove the full `AgentSessionsBrowser` UI renders every
+  viewer state correctly; that remains covered by the browser component tests.
+- No exclusions were added or widened.

+## Phase 3 Coverage Checkpoint: Throttle And Debounce Hooks
+
+Coverage-focused changes:
+
+- Added `src/__tests__/renderer/hooks/useThrottle.test.ts` for
+  `src/renderer/hooks/utils/useThrottle.ts`.
+- Covered immediate throttle execution, trailing throttle scheduling, repeated

+  debounce cancel, and canceled timer non-execution.

+- The added tests assert timing behavior and cleanup/cancellation semantics
+  rather than only invoking the hooks for coverage.
+
+Validation:
+
+- `npm run test -- src/__tests__/renderer/hooks/useThrottle.test.ts --run`
+  passed: 1 file, 3 tests passed.
+- `npm run test:coverage -- --silent` passed. The project-wide totals and
+  target file coverage above came from this run.
+
+Remaining risk:
+
+- `useThrottle.ts` is now fully covered for its local throttle/debounce timing,
+  cancellation, flush, and unmount cleanup behavior. It does not prove every
+  consumer uses these hooks with appropriate delay values; consumer behavior
+  remains covered by the relevant component and hook tests.
+- No exclusions were added or widened.
+
+## Phase 3/8 Coverage Checkpoint: Group Chat Moderator Session Cleanup
+
+Coverage-focused changes:
+
+- Extended `src/__tests__/main/group-chat/group-chat-moderator.test.ts` for
+  `src/main/group-chat/group-chat-moderator.ts`.
+- Covered process-manager-present sends when no moderator session is active,
+  stale moderator cleanup, cleanup start idempotency, cleanup stop idempotency,
+  non-stale interval passes, cleanup logging, successful chat-log reads, and
+  missing-chat failures from `getModeratorChatLog`.
+- Added a file-local `console.log` spy so existing moderator spawn debug logs no
+  longer obscure focused test output; the cleanup log remains explicitly
+  asserted in the test that expects it.

+
+Validation:

+
+Remaining risk:
+
+- `group-chat-moderator.ts` is now fully covered for local moderator session
+  mapping, sends, kills, cleanup, and chat-log lookup behavior. End-to-end group
+  chat orchestration, participant routing, and moderator synthesis remain
+  covered by the router, IPC, process-listener, and integration-style group chat
+  tests rather than this unit file alone.
+- No exclusions were added or widened.
+
+## Phase 7 Coverage Checkpoint: Update Checker Assets And Failures
+
+Coverage-focused changes:
+
+- Extended `src/__tests__/main/update-checker.test.ts` for
+  `src/main/update-checker.ts`.
+- Covered platform-specific asset readiness for macOS `.dmg`, macOS `.zip`
+  names containing `mac` or `darwin`, Windows `.msi` and `.exe`, Linux
+  `.AppImage`, `.deb`, `.rpm`, Linux-specific `.tar.gz`, non-Linux `.tar.gz`,
+  and unknown platforms.
+- Covered latest-release-without-assets behavior and non-`Error` fetch
+  failures, while keeping existing API and network failure assertions.
+- Replaced noisy focused-test logger output with a file-local logger mock and
+  explicit assertions for expected error logging.

+- The added tests exercise update-check behavior through the exported

+
+Validation:

+- `npm run test -- src/__tests__/main/update-checker.test.ts --run` passed:

+
+Remaining risk:

+- `update-checker.ts` is now fully covered for filtering, sorting,
+  update-available/no-update outcomes, platform asset readiness, empty release
+  lists, GitHub API failures, thrown network errors, and non-`Error` failures.
+  It still uses mocked `fetch`; live GitHub availability and rate-limit behavior
+  remain outside the unit suite and should stay covered by operational handling
+  rather than deterministic tests.
+- No exclusions were added or widened.
+
+## Phase 7 Coverage Checkpoint: Tunnel Manager Lifecycle
+
+Coverage-focused changes:
+
+- Extended `src/__tests__/main/tunnel-manager.test.ts` for
+  `src/main/tunnel-manager.ts`.
+- Covered tunnel startup success from `cloudflared` stderr output, startup
+  process errors, early process exits, startup timeout cleanup, late post-resolve
+  events, current-status transitions, graceful stop, and forced stop when the
+  process does not exit after `SIGTERM`.
+- Removed an unreachable timeout guard in `src/main/tunnel-manager.ts` after the
+  tests showed the false branch could not be reached through public behavior:
+  successful startup, process error, and early exit paths all clear the timeout
+  before resolving.

+
+Remaining risk:

+- `tunnel-manager.ts` is now fully covered for local tunnel lifecycle behavior,

+## Phase 3/6 Coverage Checkpoint: Document Graph Data Builder
+
+Coverage-focused changes:
+
+- Extended `src/__tests__/renderer/components/DocumentGraph/graphDataBuilder.test.ts`

+- Covered directory scan filtering for hidden files, non-markdown files, skipped
+  dependency/build folders, root scan failures, non-`Error` scan failures, and
+  nested directory read failures that should warn and continue.
+- Covered graph-building edge cases for focus-file self links, duplicate
+  external domains across documents, large-file truncation, the large-graph
+  performance threshold, batch yielding, missing stat metadata defaults, null
+  reads, and cache reuse.
+- Covered lazy backlink behavior for remaining-batch updates, link-only stat
+  failures, link-only read nulls, link-only thrown reads, large backlink files,
+  full-parse failures after link-only success, expected scan failures, and abort
+  timing before completion callbacks.
+- Covered expansion behavior for max-depth skips, missing outgoing targets,
+  second-depth node discovery, `allMarkdownFiles` parse options, duplicate edge
+  suppression, external domain grouping across source and expanded nodes, and
+  defensive duplicate parser output.

+
+Coverage-focused changes:
+
+- Extended `src/__tests__/renderer/hooks/useMergeTransferHandlers.test.ts` for
+  `src/renderer/hooks/agent/useMergeTransferHandlers.ts`.
+- Fixed the test helper so `createMockSession(overrides)` actually applies
+  overrides. Before this, several transfer tests could pass through guarded
+  assertions while exercising only the "target session not found" path.
+- Covered merge and send-to-agent no-active-session failures, the default merge
+  failure toast, missing source tabs, missing target sessions, and modal close
+  side effects.
+- Covered transfer context formatting for user, assistant, and stdout logs;
+  filtering of system/blank logs; source-name fallbacks from session name to
+  project folder to `Unknown`; groomed-transfer notices; and target session tab
+  creation/state updates.
+- Covered async spawn behavior for agent command/path fallback, missing args,
+  empty Maestro system prompt, git branch substitution, git status failure
+  capture, missing agent definitions, spawn failure error logs, SSH remote
+  config propagation, and custom session spawn parameters.
+- Covered merge callback fallbacks for missing source/target display names,
+  merge completion without a target tab, delayed merge-state cleanup, and
+  tab-switch handlers that must update only the active session.
+- Simplified the transfer token estimate after the existing filter guarantees a
+  non-empty `log.text`, removing an unreachable optional-length fallback without
+  changing valid `LogEntry` behavior.

+
+Coverage-focused changes:

+- Covered prompt generation for new and iterate modes, including loaded and
+  unloaded existing documents, empty existing-doc fallback text, explicit and
+  default iterate goals, project-name fallback behavior, and structured output
+  readiness thresholds.
+- Covered session lifecycle behavior for generated wizard session IDs, enabled
+  versus disabled SSH remote config propagation, session-level path/args/env/model
+  overrides, inactive session shutdown, process kill on shutdown, and swallowed
+  kill failures.
+- Covered send failure paths for inactive sessions, missing local agents,
+  unavailable local agents, thrown agent lookup errors, non-`Error` lookup
+  failures, spawn failures, nonzero process exits with and without extracted
+  agent session IDs, and response timeout cleanup.
+- Covered remote-session behavior where a local agent definition is absent but
+  SSH config is enabled, ensuring the spawn command falls back to the agent type
+  and SSH config is passed through.
+- Covered streamed output parsing for OpenCode text parts, Codex agent messages
+  and legacy message events, Claude/result output fallbacks, malformed JSONL
+  lines, blank lines, missing text blocks, parser fallback responses, parser
+  failure when no structured fallback exists, and extraction of `session_id`.
+- Covered callback behavior for `onSending`, `onReceiving`, `onChunk`,
+  `onComplete`, `onError`, `onThinkingChunk`, and `onToolExecution`, including
+  unrelated session IDs, empty thinking chunks, callback exceptions, listener
+  cleanup, and repeated exit cleanup.
+- Covered argument building for Claude Code without duplicating existing stream
+  args, Codex base args, OpenCode read-only args, OpenCode with no args, and
+  unknown agent fallback args.

+- Covered `isLikelyConcatenatedToolNames` for concatenated built-in Claude Code
+  tool names, whitespace trimming, concatenated MCP tool names, normal prose,
+  partial/unknown tool names, too-few tool names, and the core known-tool list
+  used by the parser guard.
+- Covered `getSlashCommandDescription` for built-in commands with and without a
+  leading slash, plugin command formatting, unknown command fallback, and empty
+  input fallback.
+- Fixed MCP tool detection so `mcp__provider__tool` matches stop before the next
+  concatenated `mcp__` token instead of greedily consuming the entire string as a
+  single tool.
+- Fixed known-tool matching to prefer longer tool names first, so
+  `TaskOutputReadWrite` is treated as three concatenated tool names instead of
+  incorrectly consuming `Task` and rejecting the remaining `Output...` text.

+## Phase 6 Coverage Checkpoint: Markdown Renderer
+
+Coverage-focused changes:

+- Extended `src/__tests__/renderer/components/MarkdownRenderer.test.tsx` for

+- Covered basic markdown, inline code, fenced code with and without languages,
+  copy-button behavior, and raw `
` fallback rendering.
+- Covered link routing for external HTTP(S) links, `file://` paths,
+  `git@host:owner/repo.git` conversion, direct `maestro-file://` links,
+  `data-maestro-file` fallbacks, relative links with no shell action, file-tree
+  markdown links, project-root absolute path links, and unsafe
+  `javascript:` scheme stripping.
+- Covered local image behavior for HTTP and `data:image/*` URLs, decoded
+  `file://` paths, SSH remote propagation, IPC loading state, module cache reuse,
+  same-render cache races, invalid image data, rejected image reads, stale
+  resolve/reject cleanup after unmount, width attributes, and missing image
+  sources.
+- Covered table wrappers/cell styling and raw `
` rendering with event
+  handler attributes stripped.
+- Added a narrow `urlTransform` so ReactMarkdown preserves protocols the
+  component already handles (`http`, `https`, `mailto`, `file`,
+  `maestro-file`, `git@`, and `data:image/*` for image sources) while continuing
+  to collapse unsafe URL schemes such as `javascript:`.

+- `MarkdownRenderer.tsx` moved from 51.38% statements, 36.36% branches, and

+- `MarkdownRenderer.tsx` is now covered for user-visible rendering behavior,

+- These tests mock Electron shell and filesystem IPC. They verify renderer
+  callback/API usage, but they do not prove that OS-level `openExternal`,

+
+Coverage-focused changes:
+
+- Added `src/__tests__/web/mobile/MobileMarkdownRenderer.test.tsx` for

+- Covered themed mobile markdown rendering with custom font size, headings,
+  strong/emphasis, links, unordered/ordered lists, list items, blockquotes,
+  horizontal rules, images with and without alt text, tables, strikethrough, and
+  GFM task-list checkboxes.
+- Covered fenced code blocks with language labels, language-less code fences
+  that display as `code`, inline code styling, dark versus light syntax style
+  selection, long-line wrapping flags, copy-to-clipboard success state, delayed
+  reset from `Copied` back to `Copy`, success haptics, rejected clipboard writes,
+  and error haptics.
+- Mocked the mobile theme hooks, syntax highlighter, clipboard, and haptics so
+  the tests assert the renderer's behavior without depending on the full mobile
+  app shell.

+
+- `MobileMarkdownRenderer.tsx` moved from 39.62% statements, 51.72% branches,
+  and no direct unit test file to high coverage over the mobile markdown behavior
+  used by `MessageHistory`.
+- The remaining target-file misses are the `
` fallback for a pre node
+  without a child code element and the non-checkbox `` fallback. The
+  component does not enable raw HTML, and ReactMarkdown/GFM do not emit those
+  branches for normal mobile AI-response markdown. They are retained as defensive

+- Mobile markdown rendering is now covered for the user-visible mobile response
+  paths: headings, text formatting, lists, tables, images, links, task lists,
+  code rendering, clipboard copy, and haptic feedback.
+- The tests mock `navigator.clipboard` and haptics. They prove that the renderer
+  calls those browser/mobile seams correctly, but not that every mobile browser
+  grants clipboard access or vibration feedback in a real device session.
+  Browser/device behavior remains an E2E/manual-mobile validation concern.
+- No exclusions were added or widened.

+## Phase 7 Coverage Checkpoint: Main Window Manager Lifecycle
+
+Coverage-focused changes:

+- Covered production `DEBUG=true` DevTools opening, fullscreen-state persistence,
+  swallowed window-state persistence errors, window closed/responsive/
+  unresponsive lifecycle logging, and Sentry reporting from unresponsive windows.
+- Covered renderer crash detection for crashed, killed, clean-exit, and destroyed
+  window cases, including delayed reload behavior only when the renderer crashed
+  unexpectedly and the window is still alive.
+- Covered webContents crash reporting for killed and non-killed crashes, page load
+  failure logging/reporting while ignoring `ERR_ABORTED`, preload script error
+  logging/reporting, renderer console error forwarding, and Sentry reporting only
+  for critical console messages.
+- Covered development auto-updater stub handler return values, install warning
+  behavior, duplicate stub registration skipping, React DevTools install failure,
+  and React DevTools installer module-load failure.

+
+Coverage-focused changes:
+
+- Extended `src/__tests__/renderer/hooks/useInterruptHandler.test.ts` for
+  `src/renderer/hooks/agent/useInterruptHandler.ts`.
+- Covered synopsis cancellation failure continuing to interrupt, default AI
+  interrupt targets when no active tab exists, idle-tab preservation during
+  normal interrupts, queue processing when no target tab exists, terminal-mode
+  queued cleanup without canceled logs, and queued item processing failures after
+  interrupt.
+- Covered force-kill fallback behavior with queued items after kill, target tab
+  state transitions, message log insertion with images, thinking/tool log
+  cleanup, queued item processing failures after kill, missing target tabs after
+  kill, successful kill preserving unrelated sessions, and successful kill
+  preserving idle tabs.
+- Covered non-`Error` kill failures, error log formatting, busy non-active tab
+  cleanup on kill failure, and preservation of unrelated sessions.

+- These are mocked component tests for renderer behavior. They do not verify real

+  listing.
+- Covered failed reporting back to the moderator when
+  `groupChat.reportAutoRunComplete` rejects, including the local `console.error`
+  path.
+- Covered the successful startup handoff for a targeted Auto Run document:
+  `listDocs` receives the configured folder and SSH remote ID, the target

+- Covered SSH create-session remote path validation when the remote filesystem
+  stat call rejects, keeping the failure visible in the create modal instead of
+  calling `onCreate`.
+- Covered create-modal agent configuration plumbing for edited custom args,
+  environment variables, model, context window, provider path, and the hook docs
+  link that opens the environment-variable documentation.
+- Covered edit-modal behavior for copying the session ID, refreshing detected
+  agent metadata, refreshing selectable models, editing args/env/config fields,
+  and saving with the keyboard shortcut.

+
+Coverage-focused changes:

+- Extended `src/__tests__/renderer/components/DocumentGraph/DocumentGraphView.test.tsx`

+- Covered file-watcher change handling for matching and non-matching roots:
+  matching changes invalidate the changed file paths and trigger a debounced
+  graph rebuild, while unrelated roots do not invalidate or rebuild.
+- Covered in-graph markdown preview navigation through linked documents,
+  back/forward history, opening the current preview file through
+  `onDocumentOpen`, and closing the preview panel.
+- Added local `console.log` spies around the new cases so expected component
+  debug logging does not add new CI noise.

+- Added a reusable MindMap fixture for document and external nodes.
+- Covered canvas open-icon hit testing for document nodes, double-click
+  recentering, background deselection followed by keyboard refocus, and opening
+  a focused external URL with Enter.
+- Derived the open-icon click target from the same layout calculation used by
+  the component so the test tracks center-node scaling instead of relying on an
+  unscaled hard-coded coordinate.

+- `npm run test -- src/__tests__/renderer/components/DocumentsPanel.test.tsx --run --silent`
+  passed: 1 file, 4 tests passed.
+- `npm run test -- src/__tests__/renderer/components/DocumentsPanel.test.tsx --run --coverage --silent`
+  passed and covered the file in isolation at 68.94% statements, 67.38%
+  branches, 69.32% functions, and 70.04% lines. The isolated number is lower
+  than the full-suite result because other component/integration suites already
+  exercise shared panel paths.
+- `npm run test:coverage -- --silent` passed and confirmed
+  `DocumentsPanel.tsx` at 89.77% statements, 81.54% branches, 92.05%
+  functions, and 91.14% lines, with the project-wide totals above.
+
+Remaining risk:
+
+- `DocumentsPanel.tsx` still has uncovered branches around drag/drop move and
+  copy indicator positioning, drag-end fallback drops, selector close paths,
+  no-document selector states, singular/plural refresh removal messages,
+  loading task-count badges, and some single-document/missing-document summary
+  variants.
+- The new tests validate the selector and queue UI contracts with local state.
+  They do not prove browser-native drag/drop fidelity beyond the non-drag
+  controls covered here.
+- No exclusions were added or widened.
+
+## Phase 4/8 Coverage Checkpoint: Group Chat Router Failure And SSH Paths
+
+Coverage-focused changes:
+
+- Extended `src/__tests__/main/group-chat/group-chat-router.test.ts` for
+  `src/main/group-chat/group-chat-router.ts`.
+- Added a focused Vitest seam around `group-chat-agent.addParticipant` so
+  `routeUserMessage` can exercise the recoverable auto-add failure branch
+  without changing production behavior.
+- Covered user-message routing when an auto-add participant write fails: the
+  failed participant is not persisted, the available session remains visible in
+  moderator context, and the moderator batch still receives the user request.
+- Covered moderator `!autorun` handling when the mentioned participant has no
+  Auto Run folder configured.
+- Covered participant spawn failure cleanup so pending participant state returns
+  to idle.
+- Covered moderator synthesis SSH wrapping from moderator remote configuration.

+- Covered selected-document metadata when file content is empty, failed
+  load-more recovery, external-domain search matching, and external-node
+  double-click no-op behavior.
+- Covered keyboard flows: Cmd/Ctrl+F search focus, Escape clearing and

+  origins lookup, and absence of Claude progressive stats subscriptions.
+- Covered generic non-Claude session starring and session naming persistence
+  through `window.maestro.agentSessions.setSessionStarred` and
+  `window.maestro.agentSessions.setSessionName`, including `projectRoot`
+  propagation when `cwd` differs.
+- Covered failed backend content search recovery with local `console.error`
+  assertion, empty search results, and no backend call when no project path is
+  available.
+- Covered opening the search panel from the activity graph with the global

+  active/history/status UI, help links, keyboard controls, and local failure
+  states.
+- Tests still mock `useSymphony`, `useContributorStats`, Electron bridge APIs,
+  and markdown rendering. They prove rendered UI behavior and bridge call
+  parameters, but not real GitHub CLI authentication, real cloning, real draft PR
+  creation, real Auto Run execution, or persisted contribution sync.
+- The remaining five uncovered statements should not be excluded without user
+  approval. Reaching 100% for those lines likely requires either small exported
+  test seams for internal callbacks or a behavior-preserving UI refactor that
+  removes unreachable callback paths.
+- Current largest missed-statement gaps after this checkpoint include `App.tsx`,

+
+Coverage-focused changes:
+
+- Extended `src/__tests__/renderer/components/LeaderboardRegistrationModal.test.tsx`
+  for `src/renderer/components/LeaderboardRegistrationModal.tsx`.
+- Covered opening the public leaderboard link through the Electron shell bridge.
+- Covered Enter-key form submission and leading-`@` normalization for GitHub, X,
+  LinkedIn, and Discord handles.
+- Covered direct submission failures from rejected API responses and thrown
+  submission errors.
+- Covered email-confirmation polling for confirmed, expired, transient-error, and
+  thrown poll states, including interval cleanup on unmount.
+- Covered recovered-auth-token retry failure, mount-time recovery rejection,
+  manual auth-token response failures, and thrown manual-token submission errors.
+- Covered resend-confirmation response failures and thrown resend failures.
+- Covered server-sync states for server ahead, already synced, local ahead, no
+  server record, unconfirmed email, invalid token, generic server error, and
+  thrown sync failure.
+- Covered layer-stack Escape routing through the registered modal layer callback.
+- No production code was changed.

+- Covered participant pending-state behavior for multiple participants, repeated
+  handoffs replacing existing response timeouts, stale timeouts, timeout log
+  write failures, and synthesis failure after timeout.

+Coverage-focused changes:
+
+- Extended `src/__tests__/renderer/components/ProcessMonitor.test.tsx` for
+  `src/renderer/components/ProcessMonitor.tsx`.
+- Covered keyboard boundary navigation: selecting the first visible node,
+  selecting the last node from an empty selection, moving between parent and
+  child nodes, opening process details with Enter, refreshing with `R`, and
+  tolerating stale selected process IDs after a refresh.
+- Covered detail-view layer Escape behavior returning to the process tree
+  without closing the modal.
+- Covered malformed process detail handling when a process has no usable PID.
+- Covered refresh spinner feedback through the 500 ms minimum display timer.
+- Covered session row click selection/toggle behavior.
+- Covered hover feedback on session rows, process rows, kill buttons,
+  group-chat rows, list header controls, and detail header controls.
+- Added centralized test cleanup for restored spies so failed assertions do not
+  leak console, DOM, or timer state into later tests.
+- No production code was changed.

+- `ProcessMonitor.tsx` moved from 86.78% statements, 82.52% branches, and
+  75.96% functions to 99.04% statements, 88.43% branches, and 99.04%
+  functions in the full suite.
+- Missed statements dropped from 55 to 4.
+- Remaining missed statements are lines 686, 688, 1167, and 1175. Lines 686
+  and 688 are a dead `ArrowDown` else-if because the preceding
+  `currentIndex < visibleNodes.length - 1` branch already handles
+  `currentIndex === -1` for non-empty trees. Line 1167 is the exhaustive
+  `renderNode` fallback after all typed node variants. Line 1175 is a null
+  guard inside `renderDetailView`, but the function is only invoked behind a
+  truthy `detailView` conditional. These should not be excluded without user
+  approval; reaching 100% for this component would require a small
+  behavior-preserving cleanup of unreachable defensive branches.
+- No coverage exclusion was added or widened.

+  passed: 1 file, 95 tests passed.
+- `npm run test:coverage -- src/__tests__/renderer/components/ProcessMonitor.test.tsx --run --silent`
+  passed and confirmed the focused file at 99.04% statements, 88.43% branches,

+- `npm run test:coverage -- --silent` passed according to
+  `/tmp/maestro-process-monitor-full-coverage.log`: 686 files passed, 1
+  skipped; 25,835 tests passed, 107 skipped. The project-wide totals are shown
+  above.
+
+Remaining risk:
+
+- The component now has strong unit coverage for tree construction from active
+  processes, grouped and ungrouped sessions, group-chat and wizard process
+  rendering, keyboard navigation, stale selection recovery, refresh polling and
+  feedback, detail-view rendering, process kill confirmation/error paths, and
+  user-visible hover/selection state.
+- Tests still mock Electron process APIs and assert component-level behavior.
+  They do not prove that the real process manager returns all expected active
+  process shapes or that process termination succeeds outside the mocked IPC
+  contract.
+- Current largest missed-statement gaps after this checkpoint include
+  `App.tsx`, `web/mobile/App.tsx`, `AutoRun.tsx`,

+
+Coverage-focused changes:
+
+- Extended
+  `src/__tests__/renderer/components/Wizard/screens/AgentSelectionScreen.test.tsx`
+  for `src/renderer/components/Wizard/screens/AgentSelectionScreen.tsx`.
+- Covered rejected SSH remote config loading and rejected remote agent detection,
+  including local console error assertions and user-visible connection errors.
+- Covered rejected existing-session lookup while keeping the screen usable.
+- Covered single-agent focus behavior, name-field blur styling, name-field
+  Enter continue behavior, tile keyboard navigation, focused-tile Enter
+  selection/continue behavior, mouse tile selection, and disabled unavailable
+  tiles.
+- Covered config-panel opening from the customize keyboard shortcut.
+- Covered config-panel remote host option rendering, remote/local dropdown
+  changes, remote detection propagation, and returning to the grid.
+- Covered initial model-load failure, model-refresh failure, and duplicate env
+  var key generation when `NEW_VAR` already exists with a value.
+- Added test cleanup for restored spies so expected console-error tests do not
+  leak mocks into later tests.
+- No production code was changed.

+- Missed statements dropped from 54 to 4.
+- Remaining missed statements are lines 550, 795, 808, and 1025. Line 550 is

+  supported tile" path because unsupported tiles come after all supported tiles
+  and the branch only runs when multiple supported agents are already detected.
+  Lines 795 and 808 are guards for refresh callbacks that are only exposed by

+  blur guard with the same constraint. These should not be excluded without user

+
+Remaining risk:
+
+- The screen now has strong unit coverage for local and remote detection,
+  user-facing SSH failure states, keyboard and mouse agent selection, wizard
+  continuation, config-panel entry/exit, model refresh failures, custom path and
+  environment variable state, and disabled/coming-soon agent states.
+- Tests still mock wizard persistence, Electron agent APIs, SSH remote config
+  loading, and the shared `AgentConfigPanel`. They prove screen wiring and
+  callback payload behavior, but not real remote detection, real model
+  discovery, or provider binary validation beyond the mocked IPC contract.
+- Current largest missed-statement gaps after this checkpoint include

+
+Coverage-focused changes:
+
+- Extended `src/__tests__/renderer/components/TerminalOutput.test.tsx` for

+- Covered terminal command echo stripping for CRLF, bare newline, and bare
+  carriage-return command output.
+- Covered older log timestamp calendar-date rendering.
+- Covered output-search layer Escape behavior through both the registered layer
+  handler and the updated layer handler, including clearing search text and
+  returning focus to the output region.
+- Covered copy notification dismissal after its timeout.
+- Covered expanded long terminal output scroll adjustment, nested wheel
+  propagation containment, and collapse back to the truncated view.
+- Covered delete confirmation scroll positioning from the returned deletion
+  index.
+- Covered local terminal output filters clearing query and mode through Escape.
+- Covered elapsed-time formatting after an hour of terminal work.
+- Covered auto-scroll distinctions between programmatic scrolls and genuine
+  user scroll-away behavior, same-tab read-state updates, tab read-state
+  restoration, scroll-position debounce replacement, scroll timer cleanup on
+  unmount, and restoring an initial scroll position.
+- No production code was changed.

+- Remaining missed statements are lines 247, 1376, 1502, and 1510. Line 247 is

+  production call sites guard on a truthy `outputSearchQuery` before calling the
+  helper. Line 1376 is the scroll handler's null-ref guard; line 1502 is the
+  MutationObserver setup null-ref guard; line 1510 is the nested auto-scroll
+  null-ref guard. These are defensive ref guards that are not reachable through

+- The component now has strong unit coverage for terminal/AI rendering,

+  positioning, expanded output scrolling, elapsed-time display, auto-scroll
+  pause/resume decisions, tab read-state decisions, scroll persistence, and
+  several terminal parsing edge cases.
+- Tests still mock clipboard, markdown rendering, ANSI conversion, layer stack,
+  and DOM scroll geometry. They prove component decisions and user-visible
+  output, but not real browser scroll physics, real clipboard permissions, or
+  markdown/ANSI rendering beyond the mocked contracts.
+- Current largest missed-statement gaps after this checkpoint include

+
+Coverage-focused changes:
+
+- Extended `src/__tests__/renderer/hooks/useBatchProcessor.test.ts` for

+- Covered missing-session diagnostics with available session IDs.
+- Covered the synchronous `useSessionStore` fallback for sessions that exist in
+  Zustand before the hook's `sessions` prop refreshes.
+- Covered reset-on-completion loop behavior when a document has only checked
+  tasks and must be reset back to unchecked work.
+- Covered pre-task error-pause skip behavior, force-kill behavior while an error
+  pause is pending, and early stop requests made before the processing loop
+  starts.
+- Covered loop continuation summaries when non-reset documents discover new
+  tasks, mixed reset/non-reset document continuation checks, reset working-copy
+  cleanup when no checkbox completion occurs, and final "completed with stalls"
+  status when only some documents stall.
+- Added a local `console.log` spy in this test file to suppress expected debug
+  output from the hook while preserving explicit `console.error`/`console.warn`
+  assertions.
+- No production code was changed.

+  430, and 432 are inside the old debounced update callback returned by
+  `useSessionDebounce`; the active `updateBatchStateAndBroadcast` path now
+  bypasses that callback with a direct update path, so these lines are not
+  reachable through current hook behavior. Lines 442-449 are callbacks passed to
+  `useTimeTracking`; the current `useTimeTracking` implementation tracks its
+  own active session set and does not call `getActiveSessionIds`, leaving that
+  callback unreachable from the parent hook. Lines 933, 1433, and 1434 are
+  narrow stop-request timing guards that require the stop flag to flip between

+
+Coverage-focused changes:

+- Extended `src/__tests__/renderer/components/NewInstanceModal.test.tsx` for

+- Covered create-modal directory conflict warnings, acknowledgement gating, and
+  nudge-message truncation before creation.
+- Covered create-side SSH path validation for stat results that are files,
+  missing/inaccessible paths, rejected stat calls, and pending SSH config
+  transfer when selecting an unavailable supported agent.
+- Covered create-side agent config panel behavior for cached model loading,
+  forced model refresh, agent re-detection, environment variable key collision,
+  removal of the final environment variable, and local config persistence
+  failures.
+- Covered edit-modal model and SSH config load failures, model refresh failure,
+  agent refresh failure, copy-session-id success feedback and timeout reset,
+  SSH validation success/missing/rejected paths, missing project-root guard,
+  nudge-message truncation, custom path/argument clears, environment variable
+  key collisions, and config persistence failure logging.
+- Added per-test default mock implementations for agent config/model/setConfig
+  and `fs.stat` in this test file so failure-path tests do not leak mock
+  behavior across cases.
+- No production code was changed.

+- The modal now has strong unit coverage for create/edit submission payloads,
+  SSH validation state, local config panel interaction, model/agent refresh
+  failures, copy feedback, conflict warnings, nudge limits, and persistence
+  error reporting.
+- Tests still mock Electron IPC, clipboard, agent detection, SSH remote config,
+  and remote filesystem stat calls. They prove UI decisions and IPC payloads,
+  but not real Electron clipboard permissions, real SSH connectivity, or real
+  provider binary discovery.
+- Current largest missed-statement gaps after this checkpoint include

+## Phase 6 Coverage Checkpoint: Auto Run Editor, Preview, And Image Race Paths
+
+Coverage-focused changes:
+
+- Extended `src/__tests__/renderer/components/AutoRun.test.tsx` for
+  `src/renderer/components/AutoRun.tsx`.
+- Covered manual save failure behavior: the editor logs the expected failure,
+  keeps the dirty content, and leaves the save affordance visible.
+- Covered uncontrolled edit/preview mode switching when no external mode
+  callback is supplied, including scroll-percentage preservation in both
+  directions.
+- Covered textarea keyboard delegation when template autocomplete consumes a
+  key before Auto Run editor shortcuts.
+- Covered command-save behavior for dirty content.
+- Covered preview-mode markdown behavior for mermaid blocks, internal
+  `maestro-file://` links, external links through `window.maestro.shell`, image
+  lightbox opening, highlighted preview search components, preview search close
+  focus restoration, and debounced match-count reset when the query changes.
+- Covered Auto Run attachment image cache fast paths, cache-populated-after-
+  render races, filesystem success/error paths for folder images, absolute
+  paths, and relative attachment paths, and stale successful/failed reads after
+  preview source changes.
+- Covered preview scroll restoration and replacement of pending preview scroll
+  notifications.
+- Covered focus restoration after document changes in edit and preview modes.
+- Covered imperative-handle guards for dirty state, no-op mode switching, and
+  no-op save when content is not dirty.
+- Covered reset-tasks guard behavior when the selected document has no backing
+  Auto Run folder.
+- No production code was changed.

+- Covered help popover close behavior, the list-level submit-to-GitHub action,
+  error-state retry, and Escape focus return from the search input.

+
+Coverage-focused changes:
+
+- Extended `src/__tests__/renderer/hooks/useGitStatusPolling.test.ts` for
+  `src/renderer/hooks/git/useGitStatusPolling.ts`.
+- Mocked the shared activity bus locally so activity debounce, unsubscribe, and
+  restart behavior can be tested deterministically.
+- Covered hidden-document polling skips with `pauseWhenHidden` enabled.
+- Covered active-session polling through `window.maestro.git.info`,
+  `gitService.getStatus`, and `gitService.getNumstat`, including terminal
+  `shellCwd`, per-session SSH remote fallback, branch/remote/ahead/behind
+  mapping, porcelain status trimming, modification detection, numstat merging,
+  total addition/deletion aggregation, and missing-numstat defaults.
+- Covered per-session git fetch failures so a broken session is dropped without
+  losing successful session status data.
+- Covered same-size status map replacement when the git session ID changes.
+- Covered polling interval stop on inactivity, continued polling while active,
+  activity debounce timer replacement, activity restart after inactivity,
+  pending debounce cleanup on unmount, visibility-change stop/start behavior,
+  and interval restart when git session count crosses the dynamic scaling
+  threshold.
+- No production code was changed.

+- Covered move-to-group submenu opening by hover and keyboard, disabled current
+  group and ungrouped states, ungrouping, moving to another group, creating a

+- The remaining `onData` fallback for AI output without a target tab appears
+  unreachable through the current `^(.+)-ai-(.+)$` parser path because AI output
+  is only classified as AI when a tab ID is present. This should be handled as a
+  future seam/policy decision rather than faked with an impossible test input.

+- Covered task failure fallback when an agent returns no error text.
+- Covered synopsis fallback when the synopsis agent returns no response.
+- Replaced the skipped max-loop test with a bounded two-loop scenario that
+  proves loop completion, max-loop exit, loop-summary history, final-loop
+  history, total Auto Run history, usage aggregation, and pluralized summaries.
+- Covered mixed reset and non-reset documents through a real loop continuation
+  without debug/history output.
+- Tightened the document-template expansion test so it verifies write-back of
+  expanded `{{CWD}}` content.
+- Covered blank git branch handling and quiet loop exits for completed
+  non-reset docs, all-reset docs, and the no-work safety check.

+- Covered duplicate handling in `extractAllMentions` after markdown formatting

+- Covered terminal-session filtering for user-mention auto-add and
+  moderator-mention auto-add, proving terminal tabs are not promoted to group
+  chat participants.
+- Attempted to cover Gemini moderator no-sandbox branches, but current
+  `createGroupChat` validation rejects `gemini-cli` as a moderator because it
+  does not advertise `supportsGroupChatModeration`. Those branches should not
+  be forced through invalid stored state without an explicit testability or

+  file directly passed: 1 file, 85 tests passed.
+- The second `npm run test:coverage` attempt passed according to

+## Phase 3 Coverage Checkpoint: Renderer Tab Helpers Unified Edge Cases
+
+Coverage-focused changes:
+
+- Expanded `src/__tests__/renderer/utils/tabHelpers.test.ts` for
+  `src/renderer/utils/tabHelpers.ts`.
+- Covered rename fallback values, closing AI tabs when legacy closed history or
+  unified tab order is missing, preserving mixed unified order entries while
+  closing AI tabs, reopening duplicate and restored AI tabs when unified order
+  is missing, creating unified closed history for file and AI tabs, and
+  restoring unified AI tabs with `null` agent session IDs.
+- Removed unreachable private fallback logic in `getCurrentUnifiedTabIndex`.
+  Both callers already pass a repaired unified order after checking it has at
+  least two entries, so the optional-order and empty-order fallback could not be
+  exercised through public behavior.

+  payload, and stopped Auto Run state notifications.
+- Removed the unreachable streaming-log fallback from

+The branch denominator dropped by two because the unreachable fallback branch was

+
+Coverage-focused changes:

+  final and interim transcription updates; disabled and unsupported start
+  no-ops; constructor disappearance between support detection and start; default
+  language fallback; speech-recognition start failures; benign and actionable
+  recognition errors; stop without active recognition; stop failure swallowing;
+  toggle start/stop behavior; and abort failure swallowing on unmount.
+- Exported the existing `triggerHapticFeedback` helper as a narrow testability

+
+Coverage-focused changes:

+  closed before the timer fires, and reconnect-limit failure reporting.
+- Removed the unreachable mount-id cleanup guard from `useWebSocket.ts`. The
+  effect has an empty dependency array, and React's dev StrictMode cleanup for

+
+## Phase 6 Coverage Checkpoint: File Preview
+
+Coverage-focused changes:
+
+- Expanded `src/__tests__/renderer/components/FilePreview.test.tsx` for
+  `src/renderer/components/FilePreview.tsx`.
+- Covered trailing-empty extensions, C1 control-character binary detection,
+  markdown image cache expiry, URL-decoded local image paths, file-tree image
+  fallback outside the cwd, unsupported markdown link protocols, full-node
+  markdown and code search matches, disabled navigation popups, repeated scroll
+  restoration for the same file, edit-to-preview scroll synchronization,
+  tab-mode escape/click-outside no-op behavior, Ctrl shortcut variants, search
+  input fall-through keys, selection-direction anchors, and textarea page
+  movement boundaries.
+- Added `_clearExpiredImageCacheForTesting` as a narrow cache-expiry seam used
+  by the production cleanup interval.
+- Removed unreachable or redundant defensive branches where rendering already
+  guarantees the DOM node or file context, and fixed edit-to-preview scroll
+  synchronization by retaining the last mounted textarea element long enough to
+  transfer its scroll percentage.

+  and unread markers for missing tabs, cycle counters without existing values,
+  and interval ticks with no pending work.
+- Removed unreachable defensive branches in
+  `src/renderer/hooks/session/useBatchedSessionUpdates.ts`: empty accumulated

+  branches, 100.00% functions, and 100.00% lines.
+
+Remaining risk:
+
+- These tests prove the rendered document graph control surface in jsdom:
+  loading, watcher rebuilds, cached external toggles, selection metadata,
+  markdown preview routing/history, context-menu routing, load-more behavior,
+  sparse node fallbacks, backlink progress updates, and local error states.
+  They do not prove canvas hit testing, real graph layout fidelity, large
+  repository rendering performance, or user-visible behavior inside Electron.
+- Residual `DocumentGraphView.tsx` branch gaps are mostly presentational
+  ternaries for hover/active styles, disabled preview-history button guards, and
+  footer label variants. Additional tests here would mostly assert styling
+  implementation details rather than higher-value behavior.
+- Document graph remains an E2E candidate because unit tests cannot prove real
+  file-system scans, markdown preview integration, or graph interaction inside
+  the packaged Electron shell.
+- Full coverage output still contains pre-existing noisy stderr from unrelated
+  Wizard integration suites.
+- No exclusions were added or widened.

+## Phase 6 Coverage Checkpoint: Mind Map Canvas Completion
+
+Coverage-focused changes:
+
+- Expanded `src/__tests__/renderer/components/DocumentGraph/MindMap.test.ts`
+  for `src/renderer/components/DocumentGraph/MindMap.tsx`.
+- Covered missing canvas drawing context, missing canvas geometry fallbacks,
+  wheel events without geometry, background context menus, keyboard focus misses,
+  external-node keyboard no-ops when no URL is available, same-column keyboard
+  sorting, and panning to offscreen keyboard navigation targets.
+- Removed redundant internal branches in
+  `src/renderer/components/DocumentGraph/MindMap.tsx`: open-icon hit testing is
+  now called only after the caller has already verified a document node,
+  rendered layout links are trusted to have already been filtered by the local
+  layout pipeline, and the wheel listener effect relies on the mounted canvas
+  ref that React has already assigned before effects run.

+- These tests prove canvas rendering setup, graph interaction callbacks,

+
+Remaining risk:
+
+- These tests prove the modal's main create/edit workflows in jsdom, including
+  validation, keyboard shortcuts, SSH remote selection, remote path validation,
+  provider refresh, clipboard fallback, custom config editing, and save/create
+  callback payloads.
+- Residual missed statements are defensive guards that are not reachable through

+  persistence, delete-agent confirmation and erase flows, group chat prompt
+  composer routing, group chat markdown/edit flash-notification callbacks, and

+- Residual `App.tsx` gaps include the cycle-position proxy, debug toast helper

+- The app shell remains an E2E candidate because unit tests cannot prove real

+- Full coverage output still contains pre-existing noisy stderr from unrelated

+- The lone missed line is the offline queue `sendCommand` false fallback before

+  effects.
+- Remaining branch gaps are mostly optional/fallback prop branches in the mobile

+- The lone missed statement is the defensive delete fallback guard

+  progress/back navigation, and child-screen callback contracts.
+- The remaining missed statements are the fade transition timer callbacks
+  (`setDisplayedStep` and fade-in cleanup), null-modal guard returns, and the
+  empty-focusable focus-trap return. In the current component, the open-state
+  sync effect immediately aligns `displayedStep` to `state.currentStep`, and
+  the rendered modal always includes header controls, so those paths are not
+  straightforward user-observable paths without a small testability seam or a
+  transition-state refactor.

+- Covered App shell callback routing for multi-session execution queue removal,
+  clear-agent-error success and no-op paths, summarize eligibility with no
+  active tab, named session selection focus restoration, create-group modal
+  open/close, Symphony close routing, right-panel tab switching, and group-chat

+  coverage.
+
+Remaining risk:
+
+- The App shell tests now prove broad jsdom-observable orchestration through
+  mocked child surfaces: startup subscriptions, empty-state actions, core
+  modal routing, notification/debug helpers, log viewer wiring, document graph
+  file-open callbacks, Gist publish callbacks, session/tab navigation, right
+  panel/toast callbacks, and group-chat view callbacks.
+- `cyclePositionRef` proxy statements remain uncovered. The underlying
+  `useSessionNavigation` behavior has direct hook tests, but App's proxy bridge
+  is not directly observable through the current mocked shell without driving
+  the full global keyboard/sidebar navigation path.
+- The `autoSendOnActivate` delayed send effect remains uncovered. This path
+  coordinates tab flags, delayed active-session validation, and `processInput`;
+  it should be covered either with a narrow seam around the delayed send or a
+  higher-level integration test that exercises the real input pipeline.
+- The Auto Run no-folder setup branch and no-active auto-refresh guard remain
+  uncovered. Attempts through the current mocked `RightPanel` path only prove
+  tab-state updates, not the App-specific setup-modal branch, so forcing these
+  would require a less-mocked panel test or a small extracted helper.
+- The `canSummarizeActiveTab` getter passed to the main keyboard handler remains
+  uncovered at the App boundary. The keyboard hook itself is tested; this App
+  getter would need a keyboard-level integration path to prove the lazy getter
+  contract end to end.
+- Full coverage output still contains pre-existing noisy expected-error stack
+  traces from unrelated suites, including `MessageHistory`, `ErrorBoundary`,
+  `ChartErrorBoundary`, missing-provider context tests, the Browserslist stale
+  data warning, the Node `--localstorage-file` warning, and the duplicate

+  mock reset between tests, loaded document content passed into iterate-mode
+  conversations, unsuccessful and thrown document-listing paths, local history
+  path `null` conversion, unsupported wizard agents, and initialization
+  failures.
+- Covered conversation cleanup on `endWizard` and `reset`, duplicate-send
+  protection, send failure fallbacks, thrown send failures, image-bearing user
+  messages, retry after failed sends, retry after cleared history, and direct
+  document-generation state setters.
+- Covered generation configuration defaults, iterate-mode generation, successful
+  empty generation results, default generation failure messages, generation
+  completion/error callback wrappers, progress messages with and without numeric
+  counts, ignored non-display chunks, thrown generation failures, and non-Error
+  generation failures.
+- No production code changed and no coverage exclusion was added or widened.

+  naming, filtered unified-tab rendering, AI overlay command callbacks, file
+  overlay hover/click lifecycle, file copy feedback, and optional file-tab
+  handler fallbacks.
+- Remaining `TabBar.tsx` branch gaps are concentrated in UI display variants
+  and optional/default branches: accessibility titles and platform labels,
+  disabled/hide combinations for drag and close controls, color/extension
+  conditional styling, overflow-scroll edge handling, missing optional parent

+
+Coverage-focused changes:
+
+- Expanded `src/__tests__/renderer/components/SettingsModal.test.tsx` for
+  `src/renderer/components/Settings/SettingsModal.tsx`.
+- Added a minimal, default-off `featureFlags.llmSettings` prop seam so the
+  dormant LLM settings panel remains disabled in production by default while
+  being reachable in tests.
+- Extracted the LLM connection check into `testSettingsLlmConnection`, a small
+  pure helper used by the modal. This preserves modal behavior while making
+  provider network success, provider API failures, malformed provider responses,
+  and missing API-key guards independently testable.
+- Covered LLM panel tab rendering, provider selection, model slug edits, API key
+  edits, OpenRouter success/API error/invalid response, Anthropic
+  success/API error/invalid response, Ollama success/API error/invalid response,
+  and missing API-key guards that normally sit behind a disabled button.
+- Covered reachable tab-button switching for Display, Themes, and General.
+- No coverage exclusion was added or widened.

+- The new tests prove the modal's jsdom-observable behavior for dormant LLM
+  settings UI, provider configuration inputs, provider connectivity checks,
+  provider-specific error handling, and tab-button navigation.
+- The testability seam is intentionally narrow: production callers do not pass
+  `featureFlags.llmSettings`, so the LLM settings panel remains disabled by
+  default. The extracted helper contains the network behavior that was already
+  inside the component.
+- Remaining `SettingsModal.tsx` branch gaps are branch-only optional/default

+
+Coverage-focused changes:

+  hidden-files toolbar title.
+- Covered header double-click root path copy feedback and the last document
+  graph shortcut callback.
+- Covered remote loading progress counters, current-folder progress text, and
+  zero-byte singular status-bar values.
+- Covered file and folder rename selection behavior, including filename stem
+  selection, full folder-name selection, and filesystem failure keeping the
+  modal open with an error.
+- Covered file delete success and failure paths, including file-tree refresh,
+  preserved expanded folders, success notification, error notification, and busy
+  state cleanup.
+- Covered terminal error directory reselection, retry countdown clearing,
+  click-outside context menu closure, filtered file mouse-down prevention, and
+  the default migrated auto-refresh interval.
+- No production code changed and no coverage exclusion was added or widened.

+
+Coverage-focused changes:

+- Expanded `src/__tests__/renderer/hooks/useWizardHandlers.test.ts` for

+- Covered slash-command discovery merging custom and agent commands only into

+- Covered stale async slash-command discovery resolving after hook unmount, so
+  late command results do not mutate session state.
+- Covered wizard state sync writing only to the active session and active tab
+  while preserving inactive wizard tab/session state.
+- Covered thinking and tool callbacks for sessions with no active tab so
+  callback delivery from the inline wizard service is ignored safely.
+- Covered history synopsis success with group metadata and verified only the
+  active tab receives `lastSynopsisTime`.
+- Covered the "nothing to report" synopsis path across multiple sessions/tabs,
+  proving only the active pending log is replaced and no history entry is saved.
+- Covered `/wizard`, launch-tab, complete, and thinking-toggle handlers across
+  multiple sessions/tabs so inactive tabs and sessions remain unchanged.
+- Covered `handleWizardComplete` and `handleToggleWizardShowThinking` no-active
+  session guards.
+- No production code changed and no coverage exclusion was added or widened.

+
+Coverage-focused changes:
+
+- Expanded `src/__tests__/renderer/hooks/useTabHandlers.test.ts` for
+  `src/renderer/hooks/tabs/useTabHandlers.ts`.
+- Covered inactive-session preservation across mapped tab close, file-tab close,
+  unified tab reorder, show-log, clear-log, toggle read-only, toggle
+  save-to-history, and toggle thinking handlers.
+- Covered replacing the active file tab without dropping sibling file-preview
+  tabs.
+- Covered reload, delete-log, clear-file-preview-history, current-tab close, and
+  stale tab close guards when the active session or active entity is missing.
+- Covered close-left and close-right confirmation race paths where the active
+  tab moves to the relevant edge before the user confirms the draft-warning
+  modal.
+- No production code changed and no coverage exclusion was added or widened.

+Remaining risk:
+
+- The tests now prove hook-level behavior for inactive-session preservation,

+- The only remaining missed statements in `useTabHandlers.ts` are the defensive

+  flow, `createTab` is called only with an existing active session and the
+  helper returns `null` only for a missing session, so forcing those lines would
+  require mocking internal helper behavior rather than exercising product
+  behavior. They are not excluded.

+  agent-session capture, reasoning-token accumulation, usage-stat aggregation,
+  and local `console.warn` handling when query-stat recording fails.
+- Covered queued message processing, queued command processing without adding a
+  user log, missing target-tab fallback, empty-tab idle transitions,
+  non-target-session preservation, and non-worktree queue-drain polling before
+  batch resolution.
+- Covered `spawnAgentWithPrompt` delegation and empty agent-args fallback.
+- Covered background synopsis resume spawning, missing synopsis agents, lookup
+  exceptions, failed synopsis process spawns, listener cleanup, main-session SSH
+  fallback, explicit session SSH override, custom session config propagation,
+  unrelated synopsis listener isolation, and empty args fallback.
+- Covered synopsis cancellation no-ops, successful kill, failed kill warning,
+  tracking cleanup, and multiple pending synopsis sessions for one Maestro
+  session.
+- No production code changed and no coverage exclusion was added or widened.

+- These are hook-level tests with mocked summarizer and tab-helper seams. They
+  prove renderer orchestration and state transitions, but not real agent
+  summarization quality or provider process behavior; those remain covered by
+  the context summarizer/service and process-manager suites.
+- Full coverage still prints pre-existing expected-error noise from unrelated
+  error-boundary/context tests. This checkpoint uses local spies for newly
+  exercised expected errors and does not broaden global log suppression.
+- The next largest missed-statement targets after this checkpoint are
+  `App.tsx` (36), `AchievementCard.tsx` (22), `PlaygroundPanel.tsx` (22),

+## Phase 6 Coverage Checkpoint: Achievement Card Share Image And Menu Fallbacks
+
+Coverage-focused changes:
+
+- Expanded `src/__tests__/renderer/components/AchievementCard.test.tsx` for
+  `src/renderer/components/AchievementCard.tsx`.
+- Covered tooltip click containment and switching between badge tooltips after
+  the outside-click listener is registered.
+- Covered share-menu click containment so menu-internal clicks do not close the
+  menu through the document listener.
+- Covered copy success state, delayed share-menu close, and delayed reset from
+  `Copied!` back to `Copy to Clipboard`.
+- Covered clipboard edge cases where canvas generation returns no blob and
+  where `navigator.clipboard.write` rejects without showing a false success
+  state.
+- Covered share-image generation with image element failures, GitHub initials
+  fallback drawing, IPC image fetch failures, and local console assertions for
+  expected image-load errors.
+- Covered share-image hands-on time formatting for subsecond and minute-only
+  values.
+- Covered copy/download image-generation failures with local `console.error`
+  assertions.
+- Covered malformed badge history records so invalid levels are omitted while
+  valid history still renders.
+- No production code changed and no coverage exclusion was added or widened.

+- The component now has strong behavior coverage around tooltip/menu
+  containment, share-image generation, image fetch/error fallbacks, clipboard
+  failure handling, download failure logging, copy-success timers, hands-on
+  time formatting, and malformed badge history.
+- The remaining missed statement is the internal `onClose` callback passed to
+  `BadgeTooltip` at line 1208. The tooltip currently destructures that prop as
+  `_onClose` and never invokes it, so this is dead internal callback wiring
+  rather than a user-reachable path. It is not excluded. If it blocks final
+  100%, prefer a tiny behavior-preserving cleanup of the unused prop over adding
+  a brittle test-only seam.
+- Remaining branch gaps are branch-only fallbacks in text wrapping, optional
+  wand/social icon drawing, and high-level badge history coloring. They are not
+  excluded.
+- Full coverage still prints pre-existing expected-error noise from unrelated
+  error-boundary/context tests. This checkpoint locally spies on expected
+  console errors and removes one jsdom navigation warning by spying on the
+  download anchor click path.

+  after unmount.
+- Covered paste events with missing clipboard items, whitespace-only text
+  trimming with cursor restoration, image clipboard items that return no file,
+  and FileReader image loads that return no data.
+- Covered pasted image insertion when both prefix and suffix newlines are
+  required, including URL-encoded markdown path generation, undo snapshots,

+## Phase 3 Coverage Checkpoint: Main Logger File Output And Platform Paths
+
+Coverage-focused changes:
+
+- Expanded `src/__tests__/main/utils/logger.test.ts` for
+  `src/main/utils/logger.ts`.
+- Added a hoisted `fs` mock for logger tests so file logging behavior is tested
+  without writing to the user's real config directory.
+- Covered file logging enable/disable, directory creation, existing directory
+  reuse, setup failure handling, file writes with and without structured data,
+  and write failure resilience.
+- Covered Windows `APPDATA` path handling, Windows fallback path handling,
+  default Windows file logging, Linux `XDG_CONFIG_HOME`, and Linux fallback
+  config paths.
+- Covered defensive disabling when the stream is already absent and runtime
+  invalid log-level filtering.
+- No production code changed and no coverage exclusion was added or widened.

+  run.
+- The remaining missed statement is line 322, the internal
+  `selectedOrigins.size === 0` guard in `firePlaygroundConfetti()`. The public
+  UI disables the fire button when no origins are selected, so this guard is not
+  normally user-reachable; it is documented here and not excluded.
+- Remaining branch gaps are mostly defensive layer/style cleanup paths and
+  keyboard shortcut alternate branches. They are not excluded.
+
+Validation:
+
+- `npx vitest run src/__tests__/renderer/components/PlaygroundPanel.test.tsx`
+  passed: 1 file, 140 tests passed.
+- `npx vitest run --coverage src/__tests__/renderer/components/PlaygroundPanel.test.tsx`
+  passed and confirmed the focused target file at 99.62% statements, 94.44%
+  branches, 100.00% functions, and 100.00% lines.
+- `npm run test:coverage` passed and confirmed the project-wide totals shown

+- The developer playground is now covered for tab navigation, layer lifecycle,
+  close behavior, achievement controls, standing ovation, keyboard mastery,
+  confetti origins/settings/copy/reset, baton preview/settings/copy/reset, style
+  injection, clipboard failures, and themed rendering.
+- Remaining risk is limited to defensive/unreachable UI guards and browser
+  behavior around disabled controls; those should not be forced through broad

+## Phase 6/9 Coverage Checkpoint: Mobile Command Input Bar
+
+Coverage-focused changes:
+
+- Expanded `src/__tests__/web/mobile/CommandInputBar.test.tsx` for
+  `src/web/mobile/CommandInputBar.tsx`.
+- Covered uncontrolled terminal input changes, Enter submission, empty-value
+  guards, and disabled terminal submission guards.
+- Covered AI keyboard submission behavior for Cmd+Enter and blocked Ctrl+Enter.
+- Covered swipe-up history wiring through the mocked `useSwipeUp` hook.
+- Covered desktop AI blur styling/callback behavior, mobile focus expansion,
+  outside-pointer collapse, delayed blur collapse when focus leaves the
+  composer, and desktop submit focus retention.
+- Tightened temporary DOM and viewport cleanup so failed assertions cannot leak
+  an outside focus target or desktop viewport setting into later tests.
+- No production code changed and no coverage exclusion was added or widened.

+  statements, 92.51% branches, and 100.00% functions in the full-suite
+  coverage run.
+- The remaining missed statements are line 286, a defensive missing-ref guard in
+  the textarea resize effect, and lines 369-371, the terminal branch inside the
+  shared `handleKeyDown` callback. Terminal mode renders a single-line ``
+  with its own inline Enter handler, so the shared textarea `handleKeyDown`
+  branch is not user-reachable through the current DOM.
+- Remaining branch gaps include disabled/empty alternate guards, defensive ref
+  and focus checks, and terminal input branches already exercised through the
+  rendered input path. These are documented and not excluded.

+Remaining risk:
+
+- The mobile command composer is now covered for terminal submission, AI
+  submission shortcuts, busy/disabled guards, history gestures, focus/blur
+  behavior, mobile expansion/collapse, and callback wiring.
+- The remaining statement gap is intentionally not hidden. Closing it would
+  likely require either a narrow event-handler seam for the shared keydown
+  callback or removing the unreachable terminal branch from that callback after
+  confirming it is not part of the public contract.

+
+Coverage-focused changes:

+- Covered layer-stack escape handling, updated layer close handlers, and the
+  no-layer-id cleanup branch.
+- Covered repeated close attempts after the closing state has rendered.
+- Covered share image generation for transparent, empty, valid rgba, and
+  invalid rgba theme colors.
+- Covered share image record-stat rendering for both new records and existing
+  records, including wrapped flavor text.
+- Covered copy outcomes for successful clipboard writes, null canvas blobs,
+  clipboard write rejection, and canvas generation failures.
+- Covered download image generation failures and leaderboard registration
+  callbacks/visibility.
+- No production code changed and no coverage exclusion was added or widened.

+
+Coverage-focused changes:

+- Covered generic provider origin loading and generic starred-session
+  persistence for non-Claude agents.
+- Covered updated layer Escape handling in list view and defensive layer
+  registration behavior when no layer id is returned.
+- Covered the guard where an active agent loses `cwd` before a provider session
+  is opened.
+- Covered scroll-triggered message pagination and no-cursor session pagination.
+- Reset shared Maestro window mocks per test so negative assertions are not
+  polluted by previous test calls.
+- Made two minimal behavior-preserving production cleanups: the initial layer
+  Escape handler now performs only its reachable list-view close behavior while
+  current session-view Escape behavior remains in the already-tested
+  `updateLayerHandler`, and scroll handlers now use the scroll event's
+  `currentTarget` instead of mutable refs.
+- No coverage exclusion was added or widened.
