Preserve both immutable v2 history writer surfaces across verification, drift detection, and repair without rewriting clean repositories. Expose loss-aware merge receipt inspection and report contracts through the public SDK, fail closed in CLI and runtime adapters, refresh compatible dependencies, and record complete PM, documentation, changelog, and test evidence.

📝 WalkthroughSummary by CodeRabbit
WalkthroughThe PR adds dual epoch-2 history hash verification and repair preservation. It adds loss-aware merge receipt evidence APIs and fail-closed reporting. It updates merge safety, tests, documentation, public-surface metadata, workflows, tooling versions, and PM records. ChangesHistory verification and merge safety
Merge receipt evidence
Tooling and release records
Estimated code review effort: 4 (Complex) | ~60 minutes Merge Risk: 🟡 Moderate · up to This PR adds loss-aware merge evidence and dual history-hash handling, but the merge path can publish merged output before its receipt is durably written; an interruption may therefore leave an artifact whose later evidence report appears complete despite missing provenance. Caller-scoped local evidence and unlinked receipt provenance add bounded integrity and security concerns, so merge should wait for this gap to be fixed or explicitly accepted.

Reviewer's GuideThe PR makes history processing and merge receipt reporting loss-aware: it preserves legacy and expanded epoch-2 hash semantics across the full lifecycle, fails closed on incomplete evidence or lossy history unions, exposes the new SDK contract through thin CLI/runtime adapters, and refreshes supporting documentation and dependencies.

Greptile SummaryThe PR makes history verification and merge evidence loss-aware while preserving compatibility with both historical epoch-2 hash surfaces.
Confidence Score: 5/5The PR appears safe to merge. No blocking failure remains.
|
| Filename | Overview |
|---|---|
| src/core/history/replay.ts | Adds paired epoch-2 hash-candidate verification and continuous-surface re-anchoring; the previous continuity defect is fixed at the current head. |
| src/core/history/history.ts | Defines canonical and legacy epoch-2 verification candidates while retaining the existing public writer hash behavior. |
| src/sdk/merge/three-way.ts | Uses continuous hash-surface synthesis for history unions and refuses output when deterministic ordering would omit patch operations. |
| src/sdk/merge/receipts.ts | Adds loss-aware receipt inspection and reports unresolved clone-local or invalid evidence as incomplete. |
| src/sdk/history-read.ts | Matches current documents against the verified historical hash variant to avoid false drift reports. |
| src/sdk/history-repair.ts | Preserves the evidenced hash variant during repair, reconciliation checks, and appended audit events. |

- Line 3: Update the managed extension metadata through the PM system-of-record
generation workflow rather than editing updated_at directly in
.managed-extensions.json; preserve the generated file’s format and values.
In `@src/sdk/merge/receipts.ts`:
- Line 141: Update the documentation for the complete property in the receipt
report type so it means every candidate receipt was read and validated
successfully, rather than implying the returned list contains all valid
receipts. Preserve the existing reconciled-receipt filtering behavior.
In `@tests/unit/cli/merge-reconcile-registration.spec.ts`:
- Around line 84-86: Update the mocked report used by the merge reconciliation
registration test so count matches receipts.length: either change count to 0 or
add a single receipt, while preserving the expected report behavior.

Keep one epoch-2 hash surface for newly synthesized union histories, compare corresponding verification candidates during repair, and cover mixed-writer suffixes and legacy candidate matches. Also align merge evidence documentation and fixtures with their filtering contract, record review evidence in PM, and retain exact 100 percent coverage and static quality gates.

Acknowledged. The walkthrough accurately captures the delivery. The reported docstring heuristic is now superseded by the exact-head repository gate: source, exported, and member docstrings are each 100%, and the full static suite passes at d738279. |
|
Acknowledged. This reviewer guide is an accurate and useful map of the SDK, CLI adapter, tests, and generated evidence in this PR. |
|
Acknowledged. The requested full review completed against the prior head; a new exact-head review is being requested after the remediation push. |
|
Acknowledged. The epoch-2 union continuity concern was valid and is fixed in d738279 with exact adjacent-endpoint regression coverage. |
|
Acknowledged as a provider limitation, not a review result: Sourcery reported quota exhaustion and supplied no findings. The existing guide was still reviewed and acknowledged separately. |
|
Acknowledged. The actionable Greptile review was carried by its inline P1 thread; that finding is fixed and regression-tested in d738279. |
|
Acknowledged. All three inline findings and the outside-diff candidate comparison were validated; the valid issues are fixed in d738279 and the generated-file false positive is documented with its authoritative pm package install provenance. |
