Preserve history identity and recover durable context across storage damage - #1194
Conversation
… damage Deliver the connected history durability work for pm-96fsma, pm-m0yjtg, pm-qw1uw6, pm-e3gn0z, and pm-wlqxg3 through shared SDK primitives and thin CLI/MCP adapters. Recover unreadable text item documents from verified replay, add explicit single-stream invalid-tail salvage with byte-preserving receipts and concurrency guards, and report incomplete baselines without runtime crashes. Retain original version addresses and historical hash surfaces through compaction. Refuse pruned or unknowable legacy numeric targets instead of returning a different state. Reserve deleted item identities and report repeated genesis records through public SDK and validation contracts. Exercise lifecycle, redaction, repeated compaction, restoration, independent branch identities, and divergent merge reconciliation with real filesystem fixtures, independent state captures, and strict history-only patch folds. Include typed PM lineage, executable recurrence evidence, recovery guidance, and generated compatibility contracts in the reviewed delivery.

@greptileai please review the complete SDK/CLI history durability delivery. Focus on corruption recovery boundaries, retained version identity, and repeated-genesis refusal. This is the initial review request for head 4c80eb3. |

✅ Action performedFull review finished. |
|
Acknowledged the automatic-review restriction. A full review was explicitly requested with @coderabbitai full review; this skipped notice is not being counted as code approval. |
|
Thanks for identifying the remaining GH-1171 diagnostic requests. I am adding explicit item ID, path and zero-length evidence to the shape refusal and verifying existing health integrity diagnostics with the same real corruption fixtures. Recovery and salvage are implemented; the final update will also enforce those fixtures on Windows. The SDK surface manifest path is sdk/public-surface.json, not src/sdk/public-surface.json. |
|
Acknowledged: all 11 measured benchmarks were unchanged for 4c80eb3. This is evidence for the measured benchmark set, not a claim that every newly introduced recovery path has identical performance. |
|
Acknowledged the covered-line and successful-test report for the initial head. The independent local exact-count gate also passed 100/100/100/100; hosted coverage must pass again on the final updated head. |
|
Acknowledged the Sourcery quota limit. This review contains no code assessment and is not actionable remediation, so it is not treated as approval. No paid upgrade will be made; the separate reviewer guide is useful and its diagnostic feedback is being addressed. |
|
Follow-up to the Sourcery guide: the missing shape diagnostics are now implemented locally with item ID, exact path, byte length and empty-file evidence. The new real-filesystem health regression also proves that existing health integrity checks already report both the malformed item path and invalid history line, without mutation; no second health scanner is needed. These changes will be included with Windows enforcement and the artifact-size fix in the consolidated update. |

Acknowledging the edited CodeRabbit walkthrough, updated at 21:26:47 UTC: the three findings are accepted. The health requirement now has a real empty-item/NUL-tail regression, and explicit Windows execution is prepared. I am checking the touched-function docstrings against the local AST-based gate rather than treating either aggregate percentage as conclusive without its population. |
…ion proof Report corrupt item identity, path and byte shape through typed SDK errors and verify read-only health diagnoses simultaneous item and history damage. Execute both new recovery suites in the required Windows job and preserve its exact workflow contract. Use metadata-only identity reservation probes, reuse the verified salvage hash epoch, and align validation success with identity diagnostics. Document touched coordinate and recovery helpers and explicitly type the reanchor epoch to stabilize the public SDK signature. Keep the public manifest export and parsed data intact while distributing compact JSON below the unchanged artifact budget. Include real filesystem finalizer tests, structured PM review closeout and the regenerated pm-changelog output. Verification: 8397 tests in 605 files; exact 100/100/100/100 coverage; full static quality, typecheck, linked PM tests, temporary recovery acceptance, packed npm/npx/bunx consumers, artifact budget, security scan and zero-vulnerability dependency audit. Frozen tracker validation reports zero history drift and identity discontinuities; historical resolution warnings are unchanged.
|
@coderabbitai full review Please review final head 1e3d6fb. All three first-round findings are fixed and replied to inline. This update also adds typed corrupt-item diagnostics, a real read-only health negative control, required Windows history suites, lossless compact manifest packaging and helper documentation. Local proof: 8397 tests, exact 100/100/100/100 coverage, full static/typecheck, temporary-tracker acceptance and packed npm/npx/bunx consumers. Please report any remaining findings on the complete delivery. |
|
@greptileai please review updated head 1e3d6fb, including the complete SDK/CLI recovery and stable-history delivery and the review fixes. Focus on identity reservation, retained hash/version semantics, lock-time recovery safety and package export compatibility. The local CLI previously reported exhausted free-review quota; please report GitHub App availability separately from substantive findings. |
|
@sourcery-ai review Updated head 1e3d6fb implements the guide finding: malformed and empty item errors identify the item/path and expose typed byte diagnostics; a real health fixture detects both empty item and corrupt history tail without writes. Please review if the available quota permits and report remaining findings or an explicit availability limitation. |

Read the complete second full review at 1e3d6fb. All three findings are reproduced with real filesystem negative controls and are being fixed in the same connected delivery. The broad scope is intentional: the PR already links five canonical PM items and their acceptance criteria, not only GH-1171. No split is requested or needed. |
|
The completed full review is acknowledged. Its three actionable findings have real failing regressions and fixes in progress. Retained quota notices and earlier-head badges are not used as substitute approval. |
…on mappings Use exclusive first-stream creation at the effective append destination, including extension redirects, so concurrent callers cannot append multiple create records. Preserve failed partial reservations for diagnosis. Keep unknown legacy offsets nullable through default, timestamp and no-op compaction without enabling numeric reads. Include item identity, path and byte size in encoding errors. Add real failing concurrency, legacy-maintenance and binary-diagnostic regressions; verify eight separate SDK processes admit exactly one genesis writer. Update Greptile to 3.5.0 without relaxing runtime or supply-chain constraints. Close pm-e3gn0z, pm-m0yjtg, pm-96fsma and pm-o3mczz with linked evidence and regenerate the changelog. Verification: 8404 tests, exact 100/100/100/100 coverage, static quality, typecheck, linked tests, temporary recovery, packed npm/npx/bunx consumers and zero-vulnerability audit.

@coderabbitai full review Please review the updated complete delivery at 70d7198. Both prior full-review rounds are addressed with real negative controls: exclusive effective-destination genesis writes, null legacy compaction mappings, and binary diagnostic context. All 8404 tests pass at exact 100/100/100/100, with full static/type gates and separate eight-process manual acceptance. Greptile is now 3.5.0. Use included review capacity only; quota limitations are not approval and no paid upgrade is requested. |

The edited summary still cites reviewed head 1e3d6fb; the current head is 70d7198. Its three findings are now fixed and individually acknowledged. The scope warning is declined: this intentionally connected delivery covers five linked canonical history items plus the review-tooling chore, with acceptance criteria in each linked PM record. It is not restricted to GH-1171. The summary remains useful for its technical review, but its stale head badge is not current-head approval. |

I found no remaining actionable findings. I checked the effective-destination create reservation, including extension overrides and concurrent genesis writes. I also checked legacy null version mappings, history target resolution, repeated-genesis refusal, salvage lock-time checks, restore recovery, binary diagnostic context, public SDK contracts, and package manifest export generation. I used the prior identity-reservation guidance for The static diff checks found no whitespace errors or unresolved conflict markers.

Separate publication proof: the existing immutable 2026.9.4 release passed fresh npm metadata, GitHub Release, npx/bunx CLI and MCP stdio/HTTP discovery, Skills/Apps journeys, and missing-bin negative controls. Fresh npm and Bun installs each completed all 11 bounded agent-session steps. These artifacts predate this PR and do not contain its changes. Current PR packed acceptance and the smaller 19,717,410-byte artifact were independently verified. |

Read the full code-backed response: it explicitly reports no remaining actionable findings at 70d7198 after inspecting the affected paths. Its separate formal-review rate-limit notice remains a limitation; the response did not execute tests. Hosted tests passed but static found missing defect evidence on the new dependency chore, now traced to its overly broad security tag. Correcting that PM classification without weakening policy or fabricating a vulnerability. |
Remove the generic security defect marker from the Greptile dependency chore: this update addressed no known vulnerability. Preserve the original metadata and correction rationale in immutable PM history rather than fabricating escape-class evidence. The unchanged terminal defect-evidence gate now passes all 122 governed defects, while its negative control still fails with both required diagnostics. Regenerate and verify the changelog after terminal closure. Runtime source, tests, dependencies and gate policy are unchanged.

@coderabbitai full review Final updated head f432fa0 only corrects PM classification and generated changelog metadata. Runtime source, tests, dependencies and gate policy are identical to the reviewed 70d7198 head. The routine Greptile chore was mistakenly tagged as a security defect despite zero known vulnerabilities. The unchanged terminal evidence gate now passes all 122 governed defects; its incomplete-defect negative control still fails. Please verify this correction and the full connected delivery using included review capacity only; do not use paid upgrades. |

Edited-report acknowledgement for 70d7198: the CodeRabbit summary added an included-review limit notice and retained older reviewed-head coverage; this is not a new full-review approval. Its separate code-backed response was read and acknowledged. The edited CodSpeed report measures stableStringify at 312.8 us versus 324.5 us, with ten unchanged benchmarks; this narrow 3.73% result is not a claim about whole-CLI speed. Existing useful-feedback reactions remain attached to both edited comments. |

Read the full final-head response and both inspection traces. Your code-backed review of f432fa0 reports no remaining actionable findings, including the append-only PM classification correction and connected history durability paths. Repository tests were not run in your sandbox; our independent 8,404-test exact-100% coverage run and all final-head hosted checks provide that evidence. The separate formal-review rate-limit footer is recorded as a limitation, not an approval. No code changes were needed from this response. |
|
Final-head edited-report acknowledgment: I read the CodeRabbit summary update at 23:10:58 UTC and retain its useful-summary thumbs-up, while recording its seven-minute formal-review limit separately from the substantive clean response. I also read the CodSpeed update at 23:11:43 UTC: one stableStringify benchmark improves 3.77% (324.5 to 312.7 microseconds), ten unchanged; the cross-runtime warning prevents treating that as a repository-wide performance claim. Its existing thumbs-up remains appropriate. |

Read the complete formal review. Its sole actionable cache finding is disproved by the current chain verifier, mandatory re-verification of chain_ok:false cache rows, cache-version invalidation, and the existing repeated metadata-scan regression. Detailed source paths and fresh 67-test proof are in the actual inline thread. No implementation change is justified. The edited summary also suggests schema parsing may fail: a fresh build and all 19 tests in action-schema-parity.spec.ts pass, in addition to the completed full typecheck and 8,404-test coverage run. Please correct those two unsupported merge-risk claims. The explicitly requested connected six-PM-item delivery is linked in the PR body; scope is not limited to GitHub issue 1171 alone. |
|
Acknowledged: the formal full review finished on exact final head f432fa0. I read its complete review and new inline finding, assessed the evidence, reran the three relevant suites, and posted the detailed false-positive rationale on the actual inline thread. The completed formal review is distinguished from the earlier rate-limited action notices. |
|
Read this empty submitted review container and its associated inline follow-up. CodeRabbit explicitly retracted the sole cache finding, confirmed the existing regression and cache-version protection, and resolved the thread. Acknowledged as retraction/resolution evidence, not a separate new full review. |
|
Final edited-summary acknowledgment: the updated report now correctly passes the connected-delivery scope check, and I retain its existing thumbs-up for the useful summary. Its older merge-risk paragraph is superseded by the explicit inline retraction at #1194 (comment). The schema-parsing suggestion is independently disproved by the fresh build and 19 passing schema-parity tests (67 focused tests total), as well as full typecheck and exact-100% coverage. All seven inline threads are resolved; the final formal review has no remaining valid actionable findings. No source or tracker changes followed final head f432fa0. |

Outcome
Make historical context recoverable without silently changing either item identity or version identity. This is one connected SDK-first delivery across five canonical history work items plus a review-tooling dependency update, with CLI/MCP contracts, recovery documentation, and real-filesystem regression coverage.
Changes
history-repair --salvage-tail/ SDKsalvageTail: preview a verified-prefix recovery, preserve prefix bytes, and append an audit receipt containing discarded-byte count and suffix digest. Refuse interior corruption, parseable discarded records, conflicting modes, invalid UTF-8, and competing writes.Canonical work
Closes #1171.
Compatibility and safety
Legacy checkpoints without a recorded original offset cannot prove a numeric version mapping. Numeric reads refuse; timestamp reads return
as_of_version: null. SDK consumers must handle that nullable value. New checkpoints record their original offset and last-compacted timestamp. MCP action schema advances to 4.11.0 and provider schema to 1.5.0.Default and timestamp compaction of legacy checkpoints remain supported and preserve unknown offsets as
null. Eight-process manual SDK acceptance proves only one concurrent genesis writer succeeds; the permanent regression suite additionally covers string and redirected extension destinations.Incompatible major upgrades remain separately owned, not silently installed: TypeScript 7 / parser compatibility, Vitest 5 / CodSpeed compatibility, and npm-package-arg 14 / supported Node floor.
Recovery is not permission to rewrite ambiguous evidence: binary corruption, unresolved merge conflicts, and identity discontinuities remain explicit refusals. Independent-branch collision prevention remains separate from the shared repeated-genesis detector.
Verification
Local verification passed:
pnpm quality:static, typecheck, and all five items' linked PM tests.pm-changelog2026.9.2 generated the six completed items under Unreleased; regeneration check passed.f432fa0b10c9f8f0359db7dd35390628dd637857: exact-commit CodeFactor/DeepScan evidence, build, typecheck, static/context gates, exact-100% coverage, version/security checks, packed smoke, package-first dogfood, and compatibility. Required-mode Sentry/telemetry passed with zero critical/high Sentry issues, 1.15% telemetry error rate, and zero missing-error-code rows. Greptile explicitly skipped for exhausted free quota; that is not an approval.Both CodeRabbit full-review rounds are addressed. The first introduced reuse of salvage's verified hash epoch and an identity-aware validation
okflag. The second replaced check-then-append identity reservation with exclusive creation and fixed unknown-offset compaction plus encoding-error context. Seven real negative controls failed before those fixes; they now pass. Added documentation for the touched helpers. An explicit existing hash-version parameter type also stabilizes the public SDK signature against equivalent inferred-union printer ordering. Fresh final-head reviews are requested after this update; unavailable/quota-limited providers are reported separately from approval.No coverage, lint, documentation, security, or analyzer threshold is weakened. PM closure records implementation and local proof, not publication; hosted checks and bot reviews must complete before merge. The existing review-loop script inventories comments, submitted reviews, inline threads, edited timestamps, and reactions after watching checks to terminal state.
Hosted static caught the dependency chore's incorrect generic
securitytag after closure: that tag declares a defect to the existing gate, but this routine minor upgrade remediated no known vulnerability. Corrected the PM tag through immutable history without changing code or gate policy. The final terminal-state gate passes all 122 governed defects, and its deliberately incomplete negative control still fails with both required diagnostics. Full exact-head preflight passed after this metadata correction.The existing published 2026.9.4 artifact predates this PR; it is not evidence that this change is already published. Automatic daily release and exact-tag recovery are verified separately from this merge.
