Docs: reconcile current durable surfaces with main (#130)

[flyingrobots]

Problem and outcome

Closes #130. Current-surface documentation mixed pending #99 acceptance with implemented recovery, and the original documentation patch became stale as authenticated reads, verification and additional migration/fence evidence landed. This PR now reconciles the crate overview, README and living v2 pages against main 2efc131e8466b458088eaf5de0a5981e636d8f85.

Delivered capabilities include complete-stage retention recovery, fenced snapshots, durable authenticated whole-blob/exact-range reads and explicit subject/depth verification. Remaining gaps are named separately: incomplete retention-stage disposition (#155), general candidate-catalog preservation of all retained closures (#125), durable production ingestion (#82), GC and compaction (#21). Prepared portions of #107 are not treated as delivered.

Contract and scope

Change kind: documentation correction and mainline integration. Candidate 26c32d05038c7a3a38eda7cb2d259177013f5bf8 merges current main into the original documentation branch. Conflict resolutions preserve both CHANGELOG histories, main's expanded fence/model evidence and every runtime declaration/export; src/lib.rs changes are rustdoc only relative to main.

Incomplete retention stages remain preserved before recovery effects pending explicit disposition. Cooperating-writer authority supplies no isolation from arbitrary raw namespace mutation. Execution failures retain typed causes and distinguish known effects, uncertain effects and durability. No deletion advice or rollback claim is introduced. Current-root verification against the current catalog is not presented as the missing general candidate-catalog gate.

Alternative rejected: publishing stale absence claims or importing unmerged #107 implementations. No runtime change, signature change, format change, dependency change, benchmark impact, recovery algorithm change or new security surface.

Validation and review

The claim/source reconciliation identifies the current owning boundaries, historical baseline, merged deliveries and limitations. No runtime assertion or expectation changes. Source-string tests would not prove storage behavior and were not added, consistent with the binding documentation-only testing rule.

Exact-tree copied-Docker validation passes: formatting, source structure, all-feature and minimal-feature workspace/all-target Clippy with warnings denied, debug/release workspace doctests and rustdoc generation. Pinned Markdown lint passes. Changed inline local link targets exist; final hosted documentation integrity supplies its broader checks. Parent #165's full runtime validation is prior mainline evidence, not a new execution claim for this documentation patch.

Independent GPT-6.1-sol review with the complete checklist found one P3 documentary inconsistency: linked contracts still described delivered #109/#114 work as candidates. Successor 35f8ba0 updates those current labels and adds exact merged-candidate acceptance links while preserving historical receipts and labeling earlier pending tables historical. Its Markdown checks pass; source and rustdoc are unchanged from locally validated integration 4f68903. CodeRabbit subsequently identified a stale migration ledger row, corrected in 26c32d0 and confirmed by CodeRabbit. Final exact-head independent APPROVE incorporates the full checklist and both documentary deltas. Markdown passes on the final successor. All feedback is reconciled; the obsolete changes-requested review is dismissed as addressed. All four final-head hosted checks pass. Code Lawyer closure records acceptance. Signed normal merge 2c0f0893b854bbc9989adcabc2f3f950d90e8c84 preserves the exact reviewed tree; post-merge checks remain pending. Earlier head 100ef3b validation is historical and is not substituted for current acceptance. Landing preflight records the reconciled claims and merge obligations.

Summary by CodeRabbit

• Documentation
  • Clarified which durable storage, retention recovery, authenticated read, verification, and migration capabilities are implemented and what their limits are.
  • Documented remaining gaps, including incomplete-stage handling, catalog closure admission, ingestion, garbage collection, and compaction.
  • Updated the changelog and requirements and evidence references to distinguish delivered behavior from pending work.

Walkthrough

The documentation now records implemented retention recovery, authenticated reads, and verification alongside their evidence limits. It identifies the general candidate-catalog retained-closure gate, ingestion, garbage collection, and compaction as outstanding. No runtime behavior or public signatures changed.

Changes

Durable-surface documentation

Layer / File(s)	Summary
Document delivered surfaces and evidence README.md, src/lib.rs, docs/testing-evidence/current-durable-surfaces.md, CHANGELOG.md	The crate and README describe retention recovery, authenticated reads, verification, and their limits. The evidence record distinguishes delivered work from remaining gaps. The changelog summarizes delivered and pending work.
Clarify version-two scope and recovery evidence docs/formats/segment-store-v2/README.md, docs/formats/segment-store-v2/requirements.md	The version-two documentation records merged implementation scope and migration evidence. It specifies incomplete-stage recovery limits and deferred automatic disposition.
State the remaining closure-admission gap docs/formats/segment-store-v2/closure.md, docs/formats/segment-store-v2/retention-publication.md, README.md	The documentation states that the general candidate-catalog retained-closure gate remains unimplemented. It distinguishes that gate from existing closure checks against the current catalog.

Before / after behavior

• observed — Modified behavior in CHANGELOG.md: Added an Unreleased changelog entry distinguishing delivered recovery, fenced authenticated reads, and explicit verification from pending ingestion, GC, compaction, and general candidate-catalog retained-closure admission.
• observed — Modified behavior in README.md: The migration-restart evidence now links to its matrix and states its limits. The section adds claims and evidence links for completed retention-stage recovery, bounded retention crash evidence, typed recovery-failure effects, writer-authority limits, authenticated whole-blob and range reads, explicit-depth verification reports, and reader-fence process-death evidence.
• observed — Modified behavior in README.md: The heading “What it does not do yet” is retained, but its content now says incomplete retention stages block publication pending explicit disposition and automatic disposal remains deferred, replacing the statement that broader retention recovery work still required corrections and acceptance review.
• observed — Modified behavior in README.md: The gap-table entries for retention recovery remediation, fenced-reader acceptance, and explicit-depth verification are replaced by a candidate-catalog preservation issue linked to #125.

Explanation

#130’s documentation changes cover retention recovery, reads, verification, the remaining #125 closure gate, and the limits on GC and compaction. The source-reconciliation table and v2 README also describe the merged migration evidence. However, docs/formats/segment-store-v2/requirements.md still labels KEEP-MIGRATION-005 “Implemented in #111 candidate” and says final review and integration are pending. That contradicts the v2 README, which says the #111/``#112 evidence is merged, and the documented current integration. The v2 pages therefore do not agree on migration status.

Code Lawyer landing preflight

PR #163 was written against main 6051abb; landing it unchanged after #164/#165 would restore stale capability claims. The branch is being integrated with current main 2efc131e8466b458088eaf5de0a5981e636d8f85 while retaining the original bounded recovery decisions and missing candidate-catalog gate.

Severity	Files	Verified issue	Acceptance check
P4	README, crate overview, v2 status, current-durable-surfaces evidence	Claims durable authenticated reads (#109), explicit verification (#114), migration evidence (#111/#112) and fence process-death evidence (#113) are absent/pending although their focused PRs are now merged.	Reconcile each claim with actual public runtime owners and merged evidence; distinguish historical baseline from current delivery.
P4	CHANGELOG, v2 requirements, crate overview merge	Integration conflicts must preserve both mainline delivery/evidence and #130's bounded-scope correction.	Both-parent diff review, no changed runtime/API/format code, documentary checks and independent exact-head review.

@codex The change remains documentation-only. No source-string runtime test will be added. Earlier green CI and provider-limit notices do not constitute final landing acceptance.

Independent review finding — current delivery labels

Independent Codex reviewer landing163_review (GPT-6.1-sol, medium) reported this verified P3 documentation finding at candidate 4f6890396f1436523d3ec37a6f95ede896a1e691:

docs/invariants/verification/README.md:3 is an unqualified current “Status: durable verification candidate … final acceptance …” and new README:88 links it while claiming delivered #165; unlike historical receipts it has no source-boundary caveat. Suggested minimal fix: update normative page status to implemented/delivered through merged #165, keeping historical acceptance ledger attribution.

Parent inspection confirms the same stale delivery status in the linked verification requirements/closure ledger and authenticated-read requirements/evidence. This is one documentary reconciliation finding. Fix the current labels and add exact merged-candidate review/check receipts; preserve historical logs and explicitly mark earlier pending tables as historical. No runtime changes or new behavior tests are indicated. The review's complete checklist and final exact-head delta verdict remain required before merge.

The recovery caller invokes admit_recovery before reopening the recovery context or executing the plan. When the root stage is complete, admit_recovery verifies its closure against the catalog loaded from HEAD. The concern that complete-root-stage recovery does not invoke this path is refuted. This does not establish closure verification for recovery paths without a complete root stage.

Independent review of Keep PR #163

Reviewer: independent Codex, GPT-6.1-sol, medium reasoning effort, agent landing163_review, applying the complete supplied agy-review protocol and repository instructions.

Exact reviewed head: 4f6890396f1436523d3ec37a6f95ede896a1e691; tree: 2fd6d4366f1f9f31e2d146fb8e47019387d74a2b; target main: 2efc131e8466b458088eaf5de0a5981e636d8f85. The isolated candidate checkout was clean. This is a documentary reconciliation review, not a new acceptance campaign for unchanged mainline storage code.

Verified findings

P3 — Current linked delivery ledgers still describe delivered reads and verification as candidates

Primary changed claim: docs/testing-evidence/current-durable-surfaces.md:33, which says old assertions that #109/#114 remain undelivered were removed from current status. Also README.md:86/:88 and docs/formats/segment-store-v2/README.md:106/:110 claim delivery and direct readers to the current contracts.

The linked current verification contract still opens with Status: durable verification candidate and pending final acceptance (docs/invariants/verification/README.md:3). Its authoritative requirement is Implemented on the PR branch, describes the candidate and says implementation does not imply merged delivery (docs/invariants/verification/requirements.md:7). The closure ledger retains an unqualified implementation-candidate status (docs/audits/114-durable-verification-scope.md:3), current/pending review table at :111 and integration obligations at :131 without a final landing disposition.

Likewise, authenticated read requirements still say final #109 acceptance pending for both durable laws (docs/invariants/authenticated-reconstruction/requirements.md:17/:18), and explicitly say their status describes a current candidate rather than merged delivery at :20. The linked evidence opens as an in-progress ledger, not acceptance (docs/testing-evidence/durable-authenticated-reads.md:3). These are current headers/status rows, unlike the explicitly dated historical receipts that should remain intact.

Concrete failure: a consumer follows the newly advertised delivered read/verification APIs to their normative requirements and is told they are still unaccepted, branch-only candidates. The reconciliation's claim that current status was corrected is therefore false. Production implementations and exports are present at this head (src/adapters/durable/store.rs:80, src/adapters/durable/snapshot.rs:96, src/adapters/verification_ingress.rs:29, src/verification/report.rs:64); this finding concerns contradictory documentation, not a missing runtime implementation.

Suggested fix: one bounded documentary correction updates the current contract/requirement headers and status rows to delivered mainline integrations #164/#165, adds exact landing attribution, and labels prior pending-review tables and baseline statements historical. Preserve original RED/GREEN receipts, candidate coordinates, unresolved #125/#82/#21/#155 scope, allocation limits and power-loss limitations. No runtime change or fabricated runtime regression is required.

No other demonstrated defect was found in the inspected documentary delta.

Verification Checklist

Exact change and merges

• Read the entire eight-file target-relative diff: CHANGELOG, README, version-two README/closure/requirements/retention-publication, current-durable-surfaces evidence and crate rustdoc. It is 105 insertions/34 deletions, with no test, format, dependency, configuration or implementation delta.
• Audited the only PR-history merge 4f6890396f1436523d3ec37a6f95ede896a1e691 against both parents: documentary parent 100ef3b9c25cf2b887b08518042519b60cba1a9f and mainline parent 2efc131e8466b458088eaf5de0a5981e636d8f85. First-parent integration imports 300 files; second-parent comparison establishes preservation of every mainline file outside the eight documentary paths. The complete second-parent src/lib.rs diff consists solely of crate documentation before the implementation/export section. There are no rerouted runtime callers or altered exports relative to main.
• Inspected conflict-resolution deltas in CHANGELOG, version-two requirements and lib.rs: both changelog histories survive, main's expanded reader/process and model evidence survive, and durable/verification/authenticated-core exports coexist unchanged with main. Mainline integration invariants are preserved by exact file equality, not an assumption that a textual merge is safe.
• Unchanged imported runtime is attributed to the independent exact-head feat: add explicit durable verification reports (#114) #165 report for 1f3991f86fa66783d88b9ac8dbb79ecd0d9a9554 and its validation receipts; that report's limitations and pending hosted gates remain separate. This review does not claim a new line-by-line audit of all 300 already-reviewed imported files.

Production paths corresponding to the revised claims

Claim/path	Source trace and result
Migration restart under authority	src/adapters/store_migration/filesystem_migration_recovery.rs:42 → :61 acquires writer authority, admits the migrating namespace, derives root identity and opens inventory; :81 supplies observation/adoption/discard/complete admission to recovery. Complete recovery uses read-only version-two namespace admission at :86. Unlike retention, pre-effect incomplete migration intent disposal is a separate documented protocol.
Explicit retention restart	src/adapters/retention/filesystem_retention_recovery.rs:142 → pinned directories :146, fresh census/observation :150, planner :159, roots :161, live closure :163, identity-bound reopen :169, executor :174, context clear :175. Errors preserve Observe/Plan/Execute boundaries.
Publication-triggered restart	src/adapters/retention/filesystem_retention_storage.rs:25 → the same recovery entry point → protected-stage refusal :42, fresh current observation :51, current catalog/closure check :56, successor/predecessor/committed evidence :57–:89. Direct and publication paths do not silently dispose of incomplete retention evidence.
Incomplete/corrupt retention stages	src/adapters/retention/recovery_planner.rs:28 → corrupt-stage priority :33–:40 → exact incomplete disposition refusals :45/:57/:69; complete head/root/manifest transitions :89 onward. Filesystem reserved discard methods at recovery :212–:223 unconditionally refuse.
Recovery effects/errors	src/adapters/retention/recovery_execution.rs:98 → one capability per step → first-error return :114, preserving typed storage source and successful prior steps; :47 exposes separate failing-capability progress. retention_storage_progress.rs:50/:84 distinguishes known effect, uncertain effect and synchronization. Filesystem root link/manifest link/head finalize/stage removal at recovery :225/:278/:302/:316/:337 preserve effects across post-syscall failures. No rollback or atomically conditional pathname unlink is promised.
Shared live closure admission	Forward filesystem_retention_catalog.rs:28 verifies this store's selected head/catalog and calls filesystem_retention_closure_admission.rs:25; recovery calls that same verifier through admission :14. It reloads bounded selected segments and invokes verify_retention_closure at :35. Current-root verification is distinct from a candidate-catalog preservation gate.
Missing general candidate-catalog gate	src/adapters/filesystem_catalog_storage.rs:13 → filesystem_catalog_current.rs:12 checks authority/stages/current head/candidate retry; filesystem_catalog_storage.rs:102 replaces catalog HEAD. No retained-root enumeration/admission against the arbitrary candidate is present. #125 remains correctly disclosed.
Fenced retention snapshot	filesystem_retention_snapshot.rs:130 → shared load_with :142 → platform/namespace/migration/root binding :148–:157 → ReaderFence :158 → collection :174. retention_view_collector.rs:86 compares before/load/after coordinates and refuses exhausted attempts. Snapshot retains the fence and selected catalog/head/manifest; selected roots are read on demand at snapshot :218, with kind, size, identity, namespace/generation/digest checks.
Store convenience and pinned reads	src/adapters/durable/store.rs:80 fixes an absolute locator; snapshot :106, reconstruction :125, exact layout :144, range :163 delegate to the pinned snapshot. durable/snapshot.rs:96 loads the shared fenced view and verifies retained anchors at :108; reconstruct :158 and range :199 resolve the exact layout and call the shared authenticated cores :169/:211. Output errors retain typed sources; caller prefixes remain untrusted on failure.
Verification	verification_ingress.rs:29 admits raw segment evidence; catalog :59/:76/:95 loads or re-admits the owned catalog and reports requested subject evidence. filesystem_retention_verification.rs:61 uses the direct root's supported set before root/catalog access :67, then shared selected-root admission :75, decode/catalog :79/:94, report :98. Report fields/constructors are private at verification/report.rs:64/:110; report provenance grants no fence or future authority. Missing selected segments retain identity and original source at ingress :106; selected-root kinds/namespaces retain typed corruption at retention verification :162.
Process-death fence evidence	tests/reader_fence_process.rs:23 → child snapshot readiness → exact live-reader EWOULDBLOCK :43 → SIGKILL/reap :48 → exclusive acquisition and same empty inode :49–:54; collector schedule :66 → kernel queue :84 → release/admission :85–:88. Child source reader.rs:34/:119 and queue observation :92 establish actual snapshot and process boundaries. These are finite Linux schedules, not physical power-loss proof or production GC.
Undelivered APIs	Preserved crate exports and GC requirement reservation support absent production durable ingestion, GC and compaction claims. No prepared #107 implementation was introduced. #82/#21/#125/#155 retain their distinct ownership.

Numbers, bounds and evidence

• No runtime constant changed. Numeric references in the changed documentation are issue/PR identifiers, version coordinates, source SHAs and existing crash/phase counts; no timing, rate, throughput or benchmark improvement is claimed.
• Migration 21 phases: src/adapters/store_migration/migration_phase.rs:57; retention 17 phases: src/adapters/retention/publication_phase.rs:49. Crash identities cover 053–073 and 036–052 respectively. xtask/src/durability_crash_case.rs:55/:68 enumerates before/during/after; crash-point :420 adds six namespace-prefix during positions instead of one. Migration total is 21 × 3 + 5 = 68. The unchanged 001–052 figure is 52 × 3 = 156. Counts describe declared coordinates, not absence of all faults.
• Retention recovered-reader receipt retention-crash-reader-oracle.md:9/:29 scopes generation one and exact root bytes to initial publication. Raw owning oracle is xtask/src/durability_crash_matrix/restart/retention_snapshot.rs:17–:54: independent snapshot generation and returned root bytes, with 1,048,576-byte selected-segment policy and no expected value taken from the recovery receipt. Calibration coordinate 046 after is historical, not a fresh Docs: reconcile current durable surfaces with main (#130) #163 run.
• Main's 343 three-operation model histories supersede the first-parent 125 count; seven operations over three positions give 7³ = 343. Main's byte-identical model/tests and expanded changelog/requirements survive integration. This figure is exploration accounting, not correctness proof.
• Linked migration fuzz envelope: fuzz/fuzz_targets/migration_format/recovery.rs:9 onward uses 256-byte intent, two presence bytes, six little-endian u16 length prefixes, each payload ≤513 bytes. Payload bound 6 × 513 = 3,078; complete selector envelope 1 + 256 + 2 + 12 + 3,078 = 3,349. These are fuzz exploration bounds, not new durable limits.
• Historical fuzz receipt migration-compatibility-fuzz/restored-fuzz-green.txt:40 pins 20,000 executions, seed 112, max length 4,096, timeout 5 seconds and RSS cap 1,024 MiB; :251/:271 records actual completion. It proves a bounded parser/planner campaign, not filesystem execution or exhaustive hostile input coverage.
• Reader-fence receipt correctly limits twenty-second watchdogs to failure detection; observed queue/readiness/errno supplies success evidence. reader_fence_process/reader.rs has no sleep-based exclusion oracle. Restored/continuous-authority GREEN receipts record both laws in debug/release; former hosted Busy and RED receipts remain historical failures rather than relabeled passes.
• Durable segment-byte policy is not a whole-snapshot cap: durable/snapshot.rs:26–:36 and :85–:88 distinguish protocol-bounded catalog, indexes/retention records and caller output. Whole and range receipts remain separate proofs. The linked verification memory claim remains scoped to 1,048,576 entries and 1,073,741,824 bytes of incremental tracked allocations, excluding encoded buffers and RSS; its original measurement/calibration attribution remains in the feat: add explicit durable verification reports (#114) #165 independent report, not a new Docs: reconcile current durable surfaces with main (#130) #163 measurement.
• Read historical accepted retention landing, recovered-reader, migration restart/compatibility, fence-process and durable read/verification evidence with their named source coordinates and limits. New prose does not enlarge physical power-loss, arbitrary namespace-race, total-memory or whole-store verification claims. The stale current-status exception is the finding above.

Standards, discussion and validation boundaries

• Read AGENTS.md, Keep Testing Standards, enforcement profile and full agy-review skill. Documentation-only exception explicitly permits static document outcome and validation without artificial runtime tests. Change kind and source-correspondence oracle are declared at current-durable-surfaces :3/:25; no runtime assertion changed, so new RED/mutation/property/fault/resource-budget campaigns are inapplicable. Repository prose has existing wrapped paragraphs; no unrelated one-physical-line-per-paragraph rule was imposed.
• Inspected the fully paginated initial queue: two global provider quota/rate-limit notices, no reviews or threads. Notices are not review approval. Parent owns final discussion/protection refresh and hosted status; this report is not READY FOR MERGE.
• Reviewer executed read-only Git status/history/diff, source/log inspections, and Docker read-only tree query. The Docker archive's tree is independently confirmed 2fd6d4366f1f9f31e2d146fb8e47019387d74a2b. No host/container tests, mutations, source changes, publication, configuration changes or subagents were executed by this reviewer. This report is the sole write.
• Inspected Docs: reconcile current durable surfaces with main (#130) #163 exact-tree validation log: formatting/source-structure, both feature-mode all-target warnings-denied Clippy, workspace debug/release doctests and rustdoc completed successfully; parent owns exit-status/script receipt. Markdown log records pinned markdownlint-cli2 0.23.2/markdownlint 0.41.1, 168 files, zero issues. These are inspected executions, not reviewer-executed tests or storage behavior evidence.
• Parent reports Docs: reconcile current durable surfaces with main (#130) #163 hosted documentation/dependency checks green; final hosted/protection gates remain parent-owned. feat: add explicit durable verification reports (#114) #165 full runtime validation and independent review are separate historical/exact-tree evidence; Docs: reconcile current durable surfaces with main (#130) #163 did not newly execute that runtime acceptance campaign.
• No unavailable mandatory documentary/source area prevented this scoped review. Unchanged imported runtime was verified by equality with reviewed mainline and attributed prior evidence, not re-audited as 300 new feature files. Finite receipts are not proof of all crashes, all races, all malformed bytes or physical power loss.

The complete successor diff changes seven linked documentary files, 17 insertions and nine deletions. Current verification contract/requirement status now says implemented on main through #165. Authenticated reconstruction requirements 009/010 and their footer now say delivered through #164, preserving managed-namespace cooperation and independent allocation bounds. The read and verification evidence introductions give exact reviewed candidate/merge coordinates and linked acceptance receipts. The verification scope ledger marks its former open tables and pending integration obligations historical and supplies final delivery attribution. Original chronological evidence and failure records remain intact.

The changed claim/source correspondence has a concrete before/after witness: baseline current headers explicitly called the APIs unaccepted branch candidates despite the new landing-page delivery claims; current headers describe their merged implementations and bound historical pending statements to their named intermediate heads. No runtime regression is invented for this prose correction.

Mandatory Verification Checklist

This report explicitly incorporates the entire Verification Checklist in the full baseline review linked above: all production paths with file/line coordinates, parallel forward/recovery and ordinary/verification boundaries, first-class both-parent merge audit, numeric/constant evidence reconciliation, repository standards, discussion coverage, inspected executions and coverage limitations. Those source coordinates describe unchanged runtime code at the current head. This successor report supplies a fresh resulting-head verdict; it does not transfer the old REQUEST CHANGES verdict as approval.

1. Every changed path and commit. Read the full seven-file diff from 4f6890396f1436523d3ec37a6f95ede896a1e691 to 35f8ba09c38640e31045ff2b4f8fe3eff7d0d876. The only new commit directly parents the baseline; there is no new merge. Read the contract headers, authoritative status rows/footers and historical caveats against every part of the consolidated finding. All identified current-status mismatches are corrected.

2. Runtime and integration preservation. Git equality confirms no successor changes in src, tests, Cargo manifest/lockfile, .github, xtask or fuzz. All baseline runtime paths, exports, constants, formats, assertions and merge-preservation conclusions remain applicable. The sole existing merge 4f68903 remains audited against both 100ef3b and target 2efc131 as recorded in the full checklist. No caller is rerouted and no mainline invariant is relaxed by this successor.

3. Feat: add fenced durable authenticated reads (#109) #164 exact delivery coordinates. Local Git gives the same tree 8dcbb1ca6d5ad39cad1ccbcae233cc51252e40a7 for reviewed candidate 9d19e2e0c3184efd5bc08c1f8cc12edd15421a93 and integration 1079551bc6b331eb9847823e7d22b22ea4c47b62. Live GitHub commit verification reports that integration's signature valid and the same tree. The linked independent review comment 5974246110 names that candidate/tree and ends APPROVE. Closure comment 5974261856 records the final exact-head review/check gate and scoped limits. Both citations support the revised attribution without claiming a packaged release or new storage behavior.

4. feat: add explicit durable verification reports (#114) #165 exact delivery coordinates. Candidate 1f3991f86fa66783d88b9ac8dbb79ecd0d9a9554 and integration 2efc131e8466b458088eaf5de0a5981e636d8f85 both have tree cd3db0105b4a6ca6daa7e7cc9e28e98d8c665544. GitHub reports the integration signature valid and the same tree. Linked independent review 5974504658 names that exact head/tree and ends APPROVE; closure 5974510981 records all four passing final jobs and the bounded merge gate. Earlier review statuses in the immutable historical review comments are not mistaken for final hosted outcomes; the closure and live runs establish completion.

5. Every new check-count/status claim. Independently queried each linked run and its paginated job list. Feat: add fenced durable authenticated reads (#109) #164 candidate run 37158962636 is completed/success at 9d19e2e; post-merge run 37159373928 is completed/success at 1079551. feat: add explicit durable verification reports (#114) #165 candidate run 37160522753 is completed/success at 1f3991f. Each has exactly four successful jobs: Rust quality gates, documentation/workflow integrity, dependency policy and runtime fuzz smoke. Also independently confirmed feat: add explicit durable verification reports (#114) #165 post-merge run 37161239415 completed/success at 2efc131 with the same four green jobs. The new documentation's count and attribution are correct.

6. Bounds, refusal and historical scope. No changed timing, size, allocation or rate constant exists. No numeric performance claim is introduced. Earlier source SHAs and measurement/crash coordinates remain unchanged; the baseline constants/figures checklist remains binding. Current status correction does not expand the finite crash/fuzz/process schedules, physical power-loss evidence, total snapshot-memory guarantees, future SnapshotBinding, production GC, candidate-catalog gate or retention authority. Enforce retained-closure admission for low-level version-two catalog publication #125/Integrate bounded CDC deduplication with durable publication #82/Implement deterministic GC planning and identity-preserving compaction #21/Design explicit disposition for incomplete retention stages #155 gaps remain unaffected.

7. Standards and evidence. This is the same documentation correction outcome declared in current-durable-surfaces. Keep's enforcement profile explicitly permits document correspondence/static validation without artificial runtime tests. git diff --check passes. Existing RED/GREEN receipts were preserved, not relabeled or transferred to a new runtime implementation. No assertion, generated test, parser or fault protocol changed.

8. Executed versus inspected versus pending. This reviewer executed read-only Git head/tree/status/diff/equality checks and GitHub comment/commit/run/job queries. Inspected 163-status-markdown.log: pinned markdownlint-cli2 0.23.2/markdownlint 0.41.1, 168 files, zero issues. The previous Docs: reconcile current durable surfaces with main (#130) #163 archive/tree validation log covers Rust source, crate rustdoc and compiling examples unchanged by this successor; it remains attributed to tree 2fd6d4366f1f9f31e2d146fb8e47019387d74a2b, not falsely renamed as a fresh successor Rust execution. The current Markdown check is successor evidence. Mainline runtime acceptance remains separately attributed to Feat: add fenced durable authenticated reads (#109) #164/feat: add explicit durable verification reports (#114) #165 receipts. Reviewer ran no host/container tests, mutations, source edits, publication, commits, configuration changes or subagents; this report is the sole write.

9. Final gate boundary. Docs: reconcile current durable surfaces with main (#130) #163's final hosted checks, paginated discussion refresh, protections and integration matching remain parent-owned. Live verification of historical Feat: add fenced durable authenticated reads (#109) #164/feat: add explicit durable verification reports (#114) #165 runs supports their new citations; it is not a substitute for Docs: reconcile current durable surfaces with main (#130) #163's resulting-head checks. This review approves the exact documentary successor, not READY FOR MERGE or an unfinished-roadmap/power-loss certification. No unavailable mandatory delta/source/evidence area blocks this scoped review.

APPROVE — exact head 35f8ba09c38640e31045ff2b4f8fe3eff7d0d876, tree f373a0cf6cc614944700ac617137da8539f7ce85.

Independent final exact-head confirmation of Keep PR #163

Reviewer: independent Codex, GPT-6.1-sol, medium reasoning effort, agent landing163_review, applying the full supplied agy-review protocol.

Reviewed head 26c32d05038c7a3a38eda7cb2d259177013f5bf8, tree 09a1cd6c830a0d4bef9a9227519def2d84a8e730, targeting main 2efc131e8466b458088eaf5de0a5981e636d8f85. Checkout was clean on entry and final confirmation.

No remaining verified finding. The later migration-status concern is closed by the single-row documentary successor.

Verification Checklist

This report explicitly incorporates the entire complete baseline Verification Checklist in the published full review and 163-independent-review.md, together with every successor check, verified landing citation and closure in 163-independent-delta-review.md for 35f8ba09c38640e31045ff2b4f8fe3eff7d0d876. Those unchanged production-path, merge, constant/numeric, standards and evidence limits remain binding. This is a fresh exact-head verdict after the additional correction.

• Read the entire delta 35f8ba0..26c32d0: one row at docs/formats/segment-store-v2/requirements.md:35. The ordinary commit directly parents 35f8ba0; no new merge or runtime path exists. Git equality confirms unchanged source, tests, manifests/lockfile, workflows, xtask and fuzz code. git diff --check passes.
• The current KEEP-MIGRATION-005 status now attributes evidence to merged Fix: validate completed migration namespaces and restart evidence (#111) #161/Complete migration restart corruption and ambiguity matrix #111 rather than saying candidate/integration pending. It explicitly includes complete-state namespace refusal and points to bounded matrix coverage and separate diagnostics. It does not weaken the normative ambiguity law, claim universal hostile-input exploration, or imply that ordinary finite test limitations make the requirement unimplemented.
• Live GitHub confirms PR #161 is MERGED, candidate 2f22d0d9097820503d2a81085bb748273de9f56d, merge 80d23f51897085bac34bb5c4db067d0627748e13. Git ancestry confirms that integration is included in the reviewed head.
• Rechecked the named complete-state path: src/adapters/store_migration/migration_recovery_execution.rs:147 calls verify_complete after accepted Complete planning and before returning a receipt; filesystem implementation filesystem_migration_recovery.rs:86 admits the version-two namespace and preserves typed NamespacePreflight cause. Linked restart matrix :52 attributes exact refusal/preservation laws and lawful published-retention success to the focused GREEN receipt. Its :22 keeps the separate Finish typed refusal audit across durable boundaries #110 diagnostic limitations explicit. Historical counterexample and correction/calibration chronology remain intact.
• No new number, performance threshold, resource cap, assertion or format change exists. The previous complete numerical/evidence reconciliation remains applicable. The original source law and bounded crash/fuzz/process evidence were not expanded.
• Reviewer executed only read-only Git/source/diff/ancestry checks and a live read-only PR-state query. Inspected 163-migration-status-markdown.log: pinned markdownlint-cli2 0.23.2/markdownlint 0.41.1, 168 files, zero issues. Prior exact-tree Rust/doctest validation remains attributed to its original tree and unchanged Rust/rustdoc sources; it is not falsely described as a new final-head execution. No host/container tests, mutations, source edits, publication, configuration changes or subagents were performed. This report is the sole write for this confirmation.
• Final Docs: reconcile current durable surfaces with main (#130) #163 hosted jobs, full queue/protection refresh and merge matching remain parent-owned gates. No unavailable mandatory delta/source area prevents this bounded review. Approval does not certify physical power loss, arbitrary raw namespace races, production GC or unfinished roadmap work.

APPROVE — exact head 26c32d05038c7a3a38eda7cb2d259177013f5bf8, tree 09a1cd6c830a0d4bef9a9227519def2d84a8e730.

APPROVE

The sole finding is fixed at 26c32d0. CodeRabbit explicitly verified the correction and resolved its thread: #163 (comment) . Independent exact-head APPROVE with verification checklist: #163 (comment) . Dismissed as addressed under the maintainer-authorized independent review workflow; final hosted CI remains mandatory.

Code Lawyer closure — final candidate 26c32d0

Candidate 26c32d05038c7a3a38eda7cb2d259177013f5bf8, tree 09a1cd6c830a0d4bef9a9227519def2d84a8e730, targets main 2efc131e8466b458088eaf5de0a5981e636d8f85. Documentation correction only; no runtime behavior, public signature, durable format or dependency change.

Item	Severity / source	Fix	Evidence / outcome
Current docs lag delivered mainline surfaces	P4 / #130	4f68903 main integration	Claims traced to current production boundaries; gaps #155/#125/#82/#21 remain explicit. Runtime declarations and exports preserved.
Linked read and verification ledgers still say candidate	P3 / independent review	35f8ba0	Current labels corrected with exact landing references; historical receipts preserved and caveated.
Migration ledger still says integration pending	P4 / CodeRabbit	26c32d0	Merged #161 evidence attributed without expanding coverage; CodeRabbit verified and resolved the thread.

Full independent checklist, first delta approval and final exact-head APPROVE reconcile all findings. Reviewer: independent Codex GPT-6.1-sol, medium effort, using the complete agy-review prompt. All review bodies, top-level discussion and inline comments were refreshed; no actionable finding remains. CodeRabbit's obsolete changes request was dismissed only after its own explicit fix confirmation and independent exact-head approval. Its rate-limited status is not counted as an approval.

Copied-Docker formatting, source structure, both Clippy feature configurations, debug/release doctests and rustdoc pass at integration 4f68903; Rust and rustdoc sources are unchanged in its documentary successors. Pinned Markdown passes on final 26c32d0. No runtime tests or mutation controls were invented for prose changes. All four final-head hosted CI jobs pass: documentation/workflow integrity, dependency policy, fuzz smoke and Rust quality gates. Repository protection retains signed commits and non-destructive history rules; no bypass requested.

Merge eligible under the maintainer's standing authorization. Deferred runtime obligations remain deferred; this PR reconciles their documentation and does not claim their completion.
