When `> 0`, the + ctx's block header height is set to this value during replay, which + makes the ante handler treat the tx as non-genesis (full sig + verification, real account numbers, sequences). +- **`ChainID`** (`string`) — originating chain ID. Used for per-tx + chain-ID override during replay if `ChainID ∈ GnoGenesisState.PastChainIDs`. +- **`Failed`** (`bool`) — true if the tx had a non-zero return code on + the source chain. Failed txs are included in the genesis for + sequence-tracking purposes but are NOT re-executed during replay + (re-executing could double-spend or succeed unexpectedly if a VM fix + makes them now pass). The replay emits a non-empty `ResponseDeliverTx` + with an error marker so indexers don't mistake the skip for success. +- **`SignerInfo`** (`[]SignerAccountInfo`) — per-signer `(Address, + AccountNum, Sequence)`. Before each historical tx is delivered, the + replay loop force-sets each signer's account number and pre-tx + sequence from this. If the account doesn't exist yet, + `auth.NewAccountWithUncheckedNumber` creates it with the specified + number, bypassing the auto-increment counter. Uniqueness of the + `(Address, AccountNum)` pair across all SignerInfo entries and + balance-init accounts is enforced by `validateSignerInfo` as a + pre-flight check in `loadAppState` (the keeper primitive does not + re-check; its name now telegraphs the precondition). +- **`GasUsed`**, **`GasWanted`** (`int64`) — source-chain gas; used by + `GasReplayMode="source"` and the replay report. + +### `GnoGenesisState` — genesis-level replay configuration + +- **`PastChainIDs`** (`[]string`) — allowlist of chain IDs from which + historical transactions originated. Only chain IDs in this slice can + override the context chain ID during replay. `PastChainIDs[0]` is + also used for sig verification of genesis-mode txs (no metadata or + `BlockHeight == 0`) when a hardfork is in progress, since those txs + were signed against the source chain. Empty = no overrides. + `PastChainIDs` MAY contain the current chain ID — this is valid for + same-chain-ID hardforks (e.g. minor fork with no external identity + change). Do NOT add validation that rejects this. +- **`InitialHeight`** (`int64`) — new chain's starting block height. + Cross-checked against `GenesisDoc.InitialHeight` via + `RequestInitChain.InitialHeight`; `loadAppState` rejects the genesis + on divergence. +- **`GasReplayMode`** (`string`) — historical-tx gas metering: + - `""` or `"strict"` (default) — new VM's gas meter is authoritative. + Historical txs may fail if gas requirements changed between chains. + - `"source"` — historical txs (`BlockHeight > 0`) bypass the new VM's + gas meter via `auth.SkipGasMeteringKey`, preserving source-chain + outcomes even when gas metering changed. Response records + `metadata.GasUsed` for audit. + +### Sequence recovery algorithm (`gnogenesis fork generate`) + +Account numbers come from one RPC call per address at halt height — +they're stable, never change once assigned. + +Sequences are harder: they advance through both genesis-mode txs and +successful historical txs, but failed txs sometimes consume a sequence +(msg-fail) and sometimes don't (ante-fail). We can't tell the two apart +without re-verifying the signature, and the tx bytes don't carry a +"sequence used" field. + +The tool uses a single-pass algorithm with buffered brute-force: + +1. **Initialisation**: for each signer, query their current sequence + at halt height (`finalSeq`). Brute-force their first successful + historical tx's signature against `[0, finalSeq]` — the matching + value is the signer's starting counter (typically `0`, or `N` if + they had `N` genesis-mode txs). + +2. **Forward pass**, block-ordered: + - **Successful tx, no pending failures**: assign current counter as + pre-tx sequence, increment counter. + - **Failed tx**: buffer it. + - **Successful tx after failed txs from same signer**: brute-force + the successful tx's signature against `[counter, counter + len(buffer)]`. + The matching value is this tx's pre-tx sequence; work backwards to + assign sequences to each buffered failed tx (ante-fails keep the + counter, msg-fails consume one). + +3. **Trailing failures** (no subsequent success): query sequence at + halt height and diff against the last known counter. + +Signature verification is offline — `GetSignBytes` only needs +`chain_id`, `account_number`, `sequence`, fee, msgs, memo, all of +which are available from the tx bytes + metadata. + +### Genesis replay flow + +1. `InitChain` → `loadAppState` validates + `state.InitialHeight == req.InitialHeight` (if set) and that + `GasReplayMode` is recognised. +2. Genesis-mode txs (no metadata or `BlockHeight == 0`) → current + genesis behaviour: package deploys, infinite gas, auto-account + creation. Sig-verify against `PastChainIDs[0]` when a hardfork is + in progress (these txs were signed with the source chain ID). +3. Historical txs (`BlockHeight > 0`) → full ante handler. For each: + a. Ctx's block header height is overridden to `metadata.BlockHeight`. + b. If `metadata.ChainID ∈ PastChainIDs`, ctx's chain ID is + overridden for sig verification. + c. If `metadata.Timestamp != 0`, ctx's time is overridden. + d. If `SignerInfo` is present, each signer's account number and + pre-tx sequence are force-set. + e. If `GasReplayMode == "source"`, ctx carries + `auth.SkipGasMeteringKey` so `auth.SetGasMeter` installs an + infinite gas meter for this tx. + f. If `Failed`, skip `Deliver` and emit an error-marker response. + Otherwise `Deliver` normally. +4. At end of loop, the replay report is emitted via logger: summary + counts (`ok` / `ok_gas_differs` / `failed` / `skipped_failed`) and + per-failure detail. +5. Consensus advances `state.LastBlockHeight` to + `GenesisDoc.InitialHeight - 1` so the next block is produced at + `InitialHeight`. + +### Replay report + +`replayReport` accumulates per-tx outcomes and emits via the `slog` +logger at the end of `InitChain`. Categories: +- `ok` — succeeded, gas matched source (or no source gas recorded). +- `ok_gas_differs` — succeeded but gas consumption differs from source. +- `failed` — delivery failed (detail logged per-failure). +- `skipped_failed` — marked `Failed` in metadata, correctly skipped. + +Summary counts at info level; each failure gets its own warn line with +source height, gas delta, and error. `replayReport.Outcomes()` exposes +the data for tooling that wants to write a structured +`replay-report.json`. + +### Tooling — `gnogenesis fork` + +Integrated into the existing `gnogenesis` CLI as a subcommand group +(`contribs/gnogenesis/internal/fork/`): + +- **`gnogenesis fork generate`** — reads the source (RPC URL / local + dir / tarball), runs sequence recovery, emits a ready-to-replay + genesis with `PastChainIDs`, `InitialHeight`, and per-tx metadata. +- **`--patch-realm PKGPATH=SRCDIR`** (repeatable, on `generate`) — + rewrites the genesis-mode `addpkg` tx for `PKGPATH` in-place with + files from `SRCDIR` before writing.
