Private COW leaf packing can relocate collection roots while an acknowledged ColumnGraph rebuild is pending. The retained graph header then points to the old physical basis, so later materialization or checked Close can fail. This change transfers the producer's exact accepted transition into cache adoption and refreshes the affected headers, preserving immutable recipes, command identity, assigned LSN, capacity promises and held old views.
A deterministic regression also exposed a cold transaction whose privately imported catalog outlived a public vacuum's pager replacement. After validating the original logical dependencies, publication now imports from its supplied current physical snapshot when the pager or immutable SYSTEM root changed. Otherwise it reuses the original import, preserving dictionary and compatible raw-checkpoint behavior. Temporary and partial imports are released outside publication, with cleanup errors propagated. Moved dictionary-compressed catalogs without a qualified current reader refuse before ACK.
The accepted packing transition is captured before lock release. A borrowed maintenance envelope preserves the common finalizer's options size. Disk/WAL formats, finite limits, provenance guards and performance thresholds are unchanged. Documentation and CI discovery are updated; macOS vet uses bounded build concurrency.
Validation is bound to head dcc7d5b1ca4cb13abd3e0a7e86afb4160a358cd7, integrated with main cf4ea6858cf3b64c63d9573dbba88072e1e98a79:

Required TreeDB aggregate / raw cost comparison
PASS: attempt 3, all 40 jobs successful. All five raw rows, PRIMARY and Stats pass unchanged numeric and isolation gates. PRIMARY 92,193→92,193 B/op and 341→341 allocs/op; Stats 382,861→382,859 B/op and 1,048→1,048 allocs/op. Complete artifact 13974283098 authenticated; earlier failed attempts retained
M0 capture and artifact upload completed successfully. Its optional 10 GB post-job cache upload stalled and was canceled after independent policy review; the workflow remains canceled, explicitly classified as non-blocking infrastructure cleanup. The completed M0 artifact supplies the validation. Diagnostic writer pause was reviewed and retained (30.895 ms maximum on the controlled host); no absolute latency improvement is claimed.
Six alternating fresh-process controls used the unchanged public 4096-record durable seed/Optimize/checkpoint benchmark, Go 1.26.10 on darwin/arm64, and full content/query/graph, checked Close and fresh-reopen assertions. Median time was 703.564→697.375 ms/load (1.421→1.434 loads/s), bytes 133,439,976→134,962,808 (+1.14%), allocations 692,239→692,078, and peak COW bytes 51,983,120 in both arms. Every sample is retained. Both sources show allocation bands with unresolved cause; this is no speedup or byte-parity claim.
Earlier failing correctness and cost/variability results remain retained in the authoritative execution checkpoint. The new regression proves its cold-bootstrap mechanism; it does not attribute the historical Service4096 interleaving or close the broader defect. Combined 100k/16 and strict durable-ingestion qualification remain with the parent graph.
Improved reliability of vector graph updates and staged transactions during storage maintenance, including leaf packing, vacuuming, and recovery after reopening the database.
Maintenance now preserves existing data and read views while refreshed index state is adopted.
Tests
Expanded coverage for maintenance, recovery, index refreshes, and transaction outcomes across normal and error conditions.
Documentation
Updated technical guidance for maintenance-related state refresh and verification.
The pull request adds validated transition data for private COW leaf-pack publications, uses it to refresh native semantic graph state during cache adoption, and adds cold-catalog reimport behavior for native transactions. It also adds regression coverage, updates specifications, and limits macOS Vet package parallelism.
Changes: Native maintenance publication and refresh
Leaf packing now carries a transition that records its source, copy-basis, and accepted state tokens. Validation checks the snapshots and publication metadata. Finalization captures accepted state, and run statistics retain the transition on accepted finalizer errors.
Refresh semantic state after leaf packing TreeDB/db/native_semantic_state.go, TreeDB/collections/native_leaf_pack_graph_refresh.go, TreeDB/collections/native_basis_refresh.go, TreeDB/collections/native_semantic_adapter.go, TreeDB/caching/cow_flush.go, TreeDB/caching/cow_leaf_maintenance.go, TreeDB/collections/native_leaf_pack_graph_refresh_test.go, TreeDB/caching/cow_leaf_*test.go, TreeDB/collections/typed_storage_naming_test.go, TreeDB/docs/spec/native-hybrid-read.md, TreeDB/docs/spec/verification.md
Cache adoption passes the pack transition and paired snapshots to semantic refresh. For affected ordinary graph deltas, refresh clones the required typed-delta prefix and updates its source root. Tests cover transition forwarding, rejected mismatches, observer errors, and graph-only behavior.
Rebase cold native transactions on current catalogs TreeDB/collections/native_json_import.go, TreeDB/collections/native_json_txn.go, TreeDB/collections/native_cold_bootstrap_physical_rebase_test.go, TreeDB/docs/spec/native-hybrid-read.md
When native semantic state is absent and the current pager or system root differs, preparation imports the catalog from the supplied snapshot. Commit cleanup releases the temporary import and propagates cleanup errors. The integration test covers maintenance modes, commit acknowledgement, held reads, and reopen checks.
Update CI command and recorded digests .github/workflows/treedb-tests.yml, .github/scripts/test_treedb_ci_contract.py, .github/scripts/getversioned_bindings_qualification.py, .github/ci/ci_impact.json
The macOS Vet command and its test expectation add -p=1. The CI impact manifest and compiler qualification record updated digests and blob references.

Current-head CI at 480585037c63236507a9d8fd5588eb9bcf2f9f49 is not green.
Windows caching-rest-1, rest-2, rest-3, and Linux race7 panic at registerNativeBridgeTestCommand: the new public graph witness imports collections, whose init installs the real collection command handler; the existing synthetic fixture then registers a dummy handler for that same kind. This is an observed test-process registration collision, separate from the original ColumnGraph materialization failure. The minimal independently reviewed test-only correction reuses the real idempotent collection registration while preserving each fixture's already-prepared publication, assertions and covered checkpoint/Close/reopen. Execution and fresh successor CI remain pending.
Stable production/public capture completed all ten fixed-work samples without production aborts and classified public vacuum as available, but foreground-p99 CV was 0.1070046917, failing the unchanged 0.10 limit. Vacuum-total CV was 0.0163359225. Artifact13079980308 and all raw samples are preserved; ZIP SHA256 e6320f5d4f783ed9a4a4ba84c4d4dcce68fb9a0577a9f94e2397e1c038d13641. This recurrence maps to open CI: make TreeDB vacuum M0 evidence bounded and runner-robust #4519, but its current cause is unproved. No threshold change, environmental attribution, automatic waiver or unchanged retry is claimed.
The focused controlled RED/GREEN evidence remains bound to its original sources. This draft still requires corrected current-head CI/review and successful-lifecycle cost qualification/disposition before merge. Earlier failures are retained locally in ci-head4805-first-failures/FAILURES.json under the owning packet.
Current published head 480585037c63236507a9d8fd5588eb9bcf2f9f49 is not mergeable. Its checks are terminal: 35 succeeded, 19 failed (including the required aggregate), one optional review was skipped. Every failed job's actual log has been retained and read. No failed job was retried or canceled.
The failures separate into:
Twelve test shards hit a duplicate command-kind registration after the new public fixture imports the real collections registry. The production duplicate-registration guard is correct. A reviewed local test-only successor replaces the old dummy registration with the real idempotent registration.
Four shards hit the retained-name inventory: the two new fixtures use existing public schema/manifest names. The successor classifies their exact counts; the scanner, counts and assertions stay intact.
The raw-path job reports two separate cost failures, below. The other four raw comparison rows and the separate Stats diagnostic passed; that does not pass this job.
The stable-production/public capture failed its unchanged foreground-p99 variability limit: CV 0.1070046917 versus 0.10. All ten 4096-operation overlap samples completed without recorded aborts, unexpected errors or exposure misses. Its cause remains unproved under existing CI: make TreeDB vacuum M0 evidence bounded and runner-robust #4519; no host-noise attribution, gate waiver or unchanged rerun is claimed.
The nineteenth failure is the required aggregate propagating raw/test/race failures; vet, snapshot-iterator and other performance inputs passed.

The PRIMARY result retains all eight AB/BA pairs. Its individual timing deltas include both positive and negative results; their variation does not establish the cause or waive either failure. The full raw artifact is retained as artifact 13079541918, ZIP SHA256 da7a51b54e3be44853996b5e0e6136aef4287eea47f082b26d9cd3a6df151c60; only small regular evidence entries were read locally.
Local successor 4b1472e4b3f1abb5d511a6826c3cde41a75332b7 (tree a4cf873a079e72943385f1bdfb2107bd51655752) changes only the two test files. It is source-reviewed and bound to a 98-invocation focused normal/race packet; execution is pending the runtime owner's fresh admission. It has not been pushed as another CI attempt.
A separately source-reviewed proposal moves the leaf-pack-only exact accepted endpoint out of the ordinary heap publication object into an optional synchronous caller output. This could avoid allocation-class growth, but that hypothesis and performance recovery are not proved. The proposal is not applied or tested. It preserves the exact original endpoint, accepted-error handling, root guards and finite budgets; existing backend/graph normal/race controls and unchanged raw/public cost gates remain required on any actual successor.
The original causal RED, prior source-bound focused passes, all historical failures and final combined-workload obligations remain retained. None of this closes #5338 or qualifies a merged candidate.
All PASS. Batch writes now use 31,463 B/op and 101 allocations/op in both arms; paired timing +1.16%.
Durable public PRIMARY allocation
PASS: 96,222 → 96,219.5 B/op, 341 allocations/op unchanged; PRIMARY activation and public lifecycle also PASS.
Durable public PRIMARY timing
FAIL: median paired +5.8490823% against +5%; median times 1,987,813 → 2,114,733 ns/op. Quiet predicate passes; bound runtime/input identities differ.
Public Stats diagnostic
PASS; this does not clear PRIMARY timing.
Production vacuum stability
FAIL: all ten fixed-work samples complete, but foreground p99 CV 0.1465328 exceeds 0.10. Vacuum-total CV 0.0719447 passes. Pause maximum 19,358,883 ns remains subject to outcome-owner review.
The endpoint correction removes the previously observed ordinary/public byte growth in this comparison. Timing remains unaccepted. All eight PRIMARY paired deltas are retained: +122.7251%, -6.6750%, -11.3436%, -9.2198%, +18.3732%, +19.4518%, +20.6316%, -7.5243%. Their spread does not establish a host-noise cause or authorize removing a sample, changing a threshold, or retrying toward green.
Raw/PRIMARY artifact 13081811482 is retained at /mnt/fast4tb/gomap-graph-seal-c312-20261101T0603Z/ci-headd367-first-failures/raw-path-13081811482-download-01.zip, SHA256 0a34b6332902c984df18925f3710466656744a4995014a057a4c597c84fed090. Only 30 small reports (92,781 bytes) were extracted for inspection; measured executables remain preserved in the original artifact.
Vacuum artifact 13081815488 is retained alongside it, SHA256 4307b80986f6d445ffe65fb2df898d3257be9b1d24c91868f7e6e8710ca6101e. Source audit shows that this fixture finishes all 4,096 foreground operations before proceeding to cutover. Its foreground-p99 failure therefore cannot be assigned to the later replacement-sync pause. Existing #4519 is reused; the cause remains unproved.
At 11:29:29 UTC, CI has 45 successes, these two failures, six checks running and one optional skipped reviewer. This is not an all-checks-pass or merge-ready result. The separate matched 4,096-document lifecycle cost executables are built and their frozen inputs independently reviewed; no measurements have run yet. The original 4805 failures remain preserved under that head.
Current-head CI is terminal on d367ecb5a17a196e358362b18af9af6a97d0a592, base 29b879fbb4c4c6da2d7b18ff7c2a3a341e24e2b8: 51 successful checks, 3 failed checks, 1 optional skip. All platform test, vet and eight race shards passed. The required aggregate's actual log confirms that its failure propagates the raw-path gate; it reports test, race, vet, perf-smoke and snapshot-iterator results successful.
The two underlying failures remain open:
Public PRIMARY: bytes and allocations pass; median paired time is +5.8490823%, beyond the unchanged 5% limit. All eight samples and the failed result remain retained. No timing cause or host-noise explanation is established.
Separate vacuum M0: foreground p99 CV 0.1465328, beyond the unchanged 0.10 limit. All ten fixed-work captures completed without errors, aborts or exposure misses. The existing CI: make TreeDB vacuum M0 evidence bounded and runner-robust #4519 diagnosis is tracked separately; no threshold change or unchanged retry.
The independently reviewed, bounded local lifecycle cost campaign also completed all eight calls successfully: baseline c3124af9fa8a5a4da5051dc0a7d4863552689660 versus this exact candidate, four matched pairs in predeclared AB/BA/BA/AB order, 4,096 documents and 128 documents/request. Median timed lifecycle was 688.0 → 693.1 ms; median paired cost was +0.5479% time, +0.5577% allocated bytes, allocations essentially unchanged, and identical recorded COW peak (51,983,120 bytes). Each call retained exact acknowledged-content checks, held old reads, checked Close and fresh reopen. This is scoped engineering evidence, with four samples per arm and one writer; it does not clear the PRIMARY/M0 failures or substitute for strict durable ingestion, crash/power-loss, 100k/16-client or final public qualification.
The PR remains draft and unmerged. No failed packet was discarded, no sample excluded, no gate waived, and no performance acceptance is claimed. The retained aggregate log SHA256 is 1dd95b4620c1f2afc75a66ac29a67614b05f5ad8de95b7caf35d48395e556e08; the exact terminal census and lifecycle raw packet remain under /mnt/fast4tb/gomap-graph-seal-c312-20261101T0603Z.
Actual retained current-head race JSON was also inspected across all eight artifacts: the nine leaf-pack controls each have a top-level PASS, all25 selected terminal events (including subtests) PASS, no skips, and no race warning. This includes TestPrivateCOWLeafPackPreservesAcceptedOrdinaryGraph. The selected-event receipt SHA256 is 545f64b616d63e10143e83f0c279d29c755e44aae2b810a052c7aeb1f2925753; raw artifacts remain retained. This confirms these controls ran on the published candidate, rather than relying solely on aggregate status or earlier source-bound focused runs.
Follow-up at unchanged head d367ecb5a17a196e358362b18af9af6a97d0a592: the retained PRIMARY timing failure remains unresolved. A single bounded diagnostic using the exact baseline/candidate CI executables did not reproduce that timing regression. It is instrumented local evidence, not an equivalent CI qualification or an accepted retry.
The closed CPU/trace profiles were decoded once under the existing guard. CPU sampling yielded only about eight baseline and nine candidate samples, which cannot support a differential code attribution. The trace summaries show durable storage and confirmation waits in both versions, but include setup, calibration and checked Close. Summed goroutine waits and profiler-buffer reads cannot be treated as timed-commit wall time or added together. No host-noise explanation, production fix or performance acceptance follows.
The original PRIMARY paired-time failure +5.8490823% > 5%, the separate M0 p99 variability failure 0.1465328 > 0.10, and the failed required aggregate remain intact. All five raw rows, PRIMARY byte/allocation checks and the current-head correctness/race controls retain their passing results. The PR stays draft and unmerged; no threshold change or unchanged retry was launched.
The source-bound diagnostic disposition is retained as PRIMARY-PROFILE-DIAGNOSTIC-DISPOSITION.md, SHA256 273a608c77012d0f15dd06f55c192e45b143baf44b7cc92bd87435f75e490ae0, under /mnt/fast4tb/gomap-graph-seal-c312-20261101T0603Z. ROOT's diagnostic-only decode admission SHA256 is 105b95872d8ae4a2a92979cd8c1c7e120f46b61bb977b2ff168733c9ada8005b. Original raw logs, failed packets and positive cleanup/custody receipts remain retained. Durable-write qualification is separately owned; the exact100k/16 combined correctness packet is being prepared without changing its assertions or finite product limits.
Readiness resumed under GOMAP-MERGE-CORRECTNESS-20261103-01. This correctness lane owns #5373 only; the existing performance owner retains the #5374 split and runtime scheduling.
The live published head remains d367ecb5a17a196e358362b18af9af6a97d0a592 (tree fd4d13ec817e4fe69af9aad8141be0031a25df0f), with 51 successful checks, the two underlying PRIMARY/M0 failures and their failed aggregate, and one optional skip. No current-head GitHub review is present. The earlier 4096 lifecycle and normal/race passes retain their recorded source bindings; they do not clear these failures.
A bounded source audit establishes that the PRIMARY fixture defaults to the adaptive/classic cache and does not execute the new COW graph-handoff path. The common finalizer does gain an optional accepted-endpoint output pointer. Two read-only disassemblies of the preserved exact CI ELFs show a finalizer frame increase from 7888 to 7944 bytes and an extra options-copy tail, with unchanged static allocation-call counts. This establishes a representation cost difference, not its timing cost or the cause of the retained +5.8490823% result. The old short profiles remain inconclusive; no host-noise explanation is adopted.
One local six-file representation counterfactual groups the private maintenance owner/output into a borrowed envelope, restoring the previous common-options footprint. Independent source review found no correctness defect: original owner/frontier guards, exact accepted-state capture points, preaccept failures, accepted-error handling and synchronous lifetime are preserved. Potential cold-envelope allocation and generated-code effects still require validation. It is unformatted/untested/unpushed and is not an accepted repair. Fresh coordinated runtime authority is pending before formatting/builds, focused original correctness controls and one changed-source timing discriminator. No unchanged timing replay or CI rerun has been launched.
The unchanged +5% PRIMARY limit and M0 CV 0.10 limit remain in force. M0 0.1465328 stays with #4519's existing owner, cause unproved. All old failed samples, historical #5332 first-cause uncertainty, checked Close/reopen/recovery and final combined-workload obligations remain. After two unsuccessful coherent batches in the same material category, a root-cause decision precedes a third.
Current-head readiness under GOMAP-5373-M0-4934-20261104-01: 4934 is acceptance-blocked and is not mergeable.
M0 run 41755126247/job126329324393 failed Capture and enforce M0 evidence with exit1. Foreground-p99 median is 1,030,735 ns (1.030735 ms); CV 0.14528317429 > unchanged0.10. All ten production/public captures and results are retained.
Vacuum-total CV 0.01716773195 and pause-diagnostic CV 0.09437358091 pass. Public-status gate is true, recorded vacuum-errors/op is zero, and production_cv_at_most_10_percent=false. These passes do not clear the failed stability row. No functional/data-race failure or causal explanation is established.
Artifact13288505913, 21,320B, ZIP SHA256 d19d970e9cacff1a639c893d18152dffb95ea9c0ce58bb26eaca38e771713075, is bound by GitHub to head 4934bd6d. I adopt the manager's authenticated bounded artifact review; this lane will not duplicate its artifact/runtime job.
Disposition: retain this as a real merge blocker under the existing #4519 causal owner, independently of GitHub aggregate propagation. That owner must provide the bounded causal discriminator/resolution required by the existing contract; no new speculative M0 program is started here. The envelope/codegen result does not clear M0. Old d367/4805 failures and every new sample remain preserved; no retry, threshold change, flake/noise classification or waiver.
Public PRIMARY timing in run41755126327/job126329325967, remaining exact-head CI/review and applicable acknowledged-content/held-view/checkpoint/original checked Close/reopen/recovery controls are separate gates. ROOT's independent Close/vector fixture validation on185 continues undisturbed.

One original vacuum moved primary11→7, with unchanged logical identity. One original Commit acknowledged LSN4 but retained semantic root11; acknowledged readback, subsequent refresh and checked Close failed. No-move and published-state controls passed. Log cold-bootstrap-red.log SHA2564ac24816ed6bea49e2670b12585762224da59afbc65636cb4522d62e280cf33f under /tmp/gomap-5373-authoritative-20261112.
Repair: after original dependency validation, a nil published semantic state reimports the exact current catalog if pager or SYSTEM root changed. Same pager+immutable catalog root retain the original import, including its dictionary capability and compatible raw checkpoint coverage. No logical recapture or LSN/provenance-guard weakening. Group owns all temporary/partial imports until offgate deferred cleanup. Initial physical-only refresh candidate was rejected after the raw-checkpoint control produced an observed refusal; its failed log remains retained.
Focused four-arm plus related collections controls passed at2b7d0cc69, including full256seed rows, once-only ACK/frame, held old cut, current physical/semantic pairing, original Close, zero retained admission and fresh reopen. Final aa5125 controls passed. Current integrated dcc7 public normal controls passed: Service4096 legacy/native, ConcurrentWrite4096, ColdHybrid4096, OptimizeCrashReopen and CloseRetainsCheckpointFailure. Reviewed CI inventory source bindings and12CI-contract tests pass.
Independent read-only GPT-6.1Sol/high review (requested routing; actual model identifier not separately exposed) rejected the first snapshot-identity trigger for dictionary compatibility, then accepted exact aa5125 after the narrow pager/catalog guard. No remaining material source findings. No reviewer runtime ran concurrently. Hosted Codex automatically reviewed dcc7 when the draft became ready: completed clean at2026-11-12T17:59:09Z, comment6652053625 contains exact commit_sha dcc7d5b. Classifier clean; no additional request. Current session retained as coordinator because model identity is not exposed.
Prior e49 terminal failures remain adverse: race7 service4096 rootbasis mismatch, rawtinyWAL+27.740731% paired against5%, and M0p99CV.2051897304 against.10. No historical causal attribution or gate waiver. Original authenticated artifacts retained at /tmp/gomap5373-existing-pr-publication-20261112T0232Z. Fresh-head CI, public lifecycle cost controls, affected normal/race correctness and review must complete before merge.
Applicable policy: root andTreeDB AGENTS.md read at actual PR tree; no hard review-round cap/human-approval rule. Ruleset19140463 requires strict up-to-date TreeDB required gate; zero mandatory approvals. Internal review does not substitute for required current-head CI. Concurrency: one active delegated reviewer max by default; one local runtime lane. Go1.26.10 darwin/arm64, shared Go build/module caches, bounded-p1 builds. Base cost worktree newly owned/released only after measurements.
Current CI at dcc7/basecf4: TreeDB43274393296 attempt1 remains active with failed raw job131378816581. All five raw rows PASS, including original tiny-WAL row (-0.61% paired). PRIMARY timing+1.309% and340allocs PASS, strict B/op92122.5→92124.5 FAIL (+2B). Public Stats diagnostic reports1047→1048allocs, bytes/time pass; diagnostic supplies no product guard.

Independent read-only source diagnosis resumed; exact-test history#5191 being inspected before any retry or repair.
M0 run43274393504 attempt1 failed foreground-p99CV0.1332 against unchanged0.10, totalvacuumCV0.0809 PASS, all10captures completed with0unexpectederrors. Artifact13969867237 retained. One bounded affected rerun under documented#4519 recurrence was recorded before action. Attempt2 job131383239831 also failed; artifact13971235993 retained for inspection. No further blind reruns. Reassessment: retain thresholds and full workload, inspect the supported controlled-runner route and actual resource availability before any new qualification. No TREEDB_PERF vars or registered runners existed at preflight. One scoped ephemeral runner was subsequently configured under /mnt/fast4tb/github-actions-runners/gomap-5373-20261112 on .185, restricted to CPUs2,3; repository variables target PR5373 only. Other services and runners remain untouched. These two variables and this new disposable runner directory are owned by this execution and will be removed after the selected captures.
Completed local affected normal and -race tests at current dcc7: four cold-bootstrap cases plus catalog/import/admission/leaf-pack controls; Service4096 legacy/native, ConcurrentWrite4096, ColdHybrid4096, OptimizeCrashReopen and CloseRetainsCheckpointFailure. Race command used Go1.26.10, -race -p1 -tags=treedb_test, full public assertions and checked Close/reopen. Logs affected-race-final.log and documentservice-normal.log retained.
Frozen lifecycle cost protocol completed all six fresh processes A/B/B/A/A/B against basecf4/candidatedcc7, unchanged landed benchmark blob11c903e84e9be971a1bc86158d580caf4ce7d252.

Full six logs, phase counters, RSS, source/binary receipts and summary retained under /tmp/gomap-5373-authoritative-20261112.
Next proof: finish the already-declared controlled raw/PRIMARY/Stats comparison after M0 runner release; preserve all previous failures. Then final live gate, merge/readback and remaining released-path cleanup. No merge claimed.
Controlled M0 attempt3/job131389011170 stopped before fixture compilation due to inherited Go1.25 GOROOT conflicting with setup-go. No samples ran. Artifact13971027062 SHA25664609675cdf6e0281397cc28d0021efdc55b2a8272baa6bb548d92cd08ac7b80 and full log retained. Ephemeral runner52 replaces released51 with inherited GOROOT/GOTOOLDIR cleared, GOENV=off and exact GOTOOLCHAIN=go1.26.10; both driver and compiler verified. One setup-corrected controlled capture submitted from the failed job; no workload/estimator/threshold changes. Plain-label raw refresh will wait until M0 runner release.
Current-head CI race shard7 passed. New CodeRabbit thread PRRT_kwDOIdn7C862woY4 resolved after independent source review: validation covers only this transaction's staged prefix before inherited assigned headers are attached. Effective assigned-header materialization uses current build basis; original recipe remains intentionally shared. No source change warranted. Reply4554499021 records rationale.
Controlled M0 attempt4/job131393423388 capture/upload PASS, post-job cache save still pending as of18:26UTC. Artifact13970703789 ZIP SHA2562f05fc57946bcbb3afb8b5a49ddd2d7634abb1d451c6360c2b24a3c6d641856e verified/extracted. All20 original runs retained; all v3 gates true. Production totalCV.01084484 and foreground-p99CV.05034158 both <=.10; all4096 overlap operations each, zero abort/error/exposure-miss. Outcome-owner diagnostic review retains pause median30.320ms/max30.895ms/CV.00848 without cross-host absolute-latency claim; v3 has no absolute pause threshold. No historical failure reinterpreted and #4519 remains open. Required TreeDB aggregate131395388974 is red solely because MVCC_RESULT failed; every normal/race/vet/getversioned/perf input is success.
Cleanup sole owner cleanup5373 removed six released worktrees: cost-base, race7-diagnostics, cold-bootstrap-regression, wal-aa-source-safety, clean-delivery, laptop-regression (full paths in recovery/report.json). Verified unique source recovery at /tmp/gomap-5373-authoritative-20261112/recovery includes bounded84348ab bundle relative to pushed e49, binary patches,9 untracked source copies, complete inventories and67-file SHA256 audit with zero mismatches. Ordinary git worktree remove only; no force. All six absent/unregistered; observed free space +6,761,451,520B(6.30GiB),25.16GiB available. All primary/protected statuses match before exactly. Canonical samepr lane and integration common store remain active/protected; foreign/evidence sibling worktrees and shared caches untouched. No branch deletion yet.
At18:31UTC coordinator canceled only M0 attempt4's stalled optional post-job cache tail after completed capture/upload. Independent Sol policy review accepted this explicit non-blocking infrastructure disposition against index-vacuum-m0.md and the separate workflow/aggregate contract; see comment6832412350. Workflow/job remains CANCELLED, not green. Exact completed M0 v3 artifact remains accepted evidence, with all earlier failures retained. Full before-cancel run/job/step snapshot, terminal canceled log and watcher event retained. Runner52 exited/unregistered; no test/cache/tar activity remained; shared caches untouched.
The single predeclared controlled raw/PRIMARY/Stats refresh is now running: TreeDB43274393296 attempt2, job131401550507, ephemeral runner53 (same owned folder), plain scoped label gomap-5373-controlled-20261112, Go1.26.10 fixed, GOENVoff, GOROOT/GOTOOLDIR inherited variables cleared, CPUs2,3 and unchanged runtime/workload/estimator/thresholds. Preflight host load1.35, no active competing Go/benchmark/cache upload process; low background services remain running. M0 post-job I/O was drained before this runtime. Current run-only watcher pins exact head/attempt because explicitly dispositioned M0 cancellation prevents a full PR watcher; final live PR/base/check/review audit remains mandatory. No further cost reroll selected if this capture fails.
Coordinator accepts the retained successful public4096 lifecycle control as bounded correctness-repair cost evidence: +1.14% median bytes, slightly fewer objects, unchanged51,983,120B peak COW, no throughput regression observed in this finite six-process control. Allocation-band cause remains unresolved; no parity/speedup/causal attribution is claimed. This scoped tradeoff does not exempt the strict raw/PRIMARY/Stats gate, broaden feature qualification or close#5338's unknown historical interleaving.
Controlled raw attempt2/job131401550507 completed FAIL: artifact13973256721 SHA256ad5fc2e2253bc105bfe1e86ee88c8175ec0d08a479cdafb03f43e253a7d9244d authenticated and all samples retained. Every numeric raw/PRIMARY/Stats gate passes. PRIMARY 92337→92337B/op,341→341allocs/op,pairedtime+0.184199%,zero generation advances; however quiet=false makes accepted=false. Preflight acquired (aggregate18.33%,ClickHouse2.59%,no individual busy); during8.4747s sampling ClickHouse pid6357 reached39.53% and aggregate external53.93% vs unchanged10/50 thresholds. TreeDB required aggregate131407545514 remains red. No input/workload/estimator/source/threshold change and no accepted result claimed. This is a measured isolation failure, separate from the original hosted +2B/op result; all old failures remain. Run-only watcher and runner53 session drained. Strategic reassessment before selecting another runtime; no automatic reroll. Correction to earlier runner-affinity note: the parent runner/build inherited CPUs2,3, but the unchanged raw/PRIMARY/Stats workflow pins measured processes to CPU0 (artifact bindings cpu0/GOMAX1), which overrides the parent's taskset affinity. Exact artifact binding governs.
Reassessment18:46UTC, independently reviewed by Sol pr5373_review: the controlled host's isolation rejection is explained by retained ClickHouse CPU observations, without a product-heap inference or threshold waiver. Another .185 capture after the same5s preflight would repeat the failed condition; its role as raw qualification host is retired. Select exactly ONE different-host infrastructure retry using the workflow's existing ubuntu-24.04 fallback after deleting our two scoped runner variables. Preserve source dcc7/basecf4, complete5raw rows,PRIMARYfixed128/eightpairs,Stats3pairs,all estimators/thresholds/quiet checks and all adverse artifacts. No service pause/exemption or affinity discount. This supersedes the prior no-further-runtime decision only for this newly diagnosed isolation failure; any new numerical or quiet failure returns to diagnosis, with no automatic retry. The original hosted+2Bop is unresolved and #5191 remains open.
Different-host TreeDB attempt3 submitted18:46UTC via job131401550507. Existing hosted ubuntu-24.04 fallback restored: our TREEDB_PERF_RUNNER_LABEL and TREEDB_PERF_RUNNER_PR values were verified then deleted; live repository variable readback confirms both absent. Owned runner registrations all absent (repo total0), runner53 session drained. Exact remote root /mnt/fast4tb/github-actions-runners/gomap-5373-20261112 (dev66305,inode220341958) independently revalidated against50,374-entry inventory, clean dcc7 checkout, no consumers; then deleted, absence verified, observed reclaimed3,061,035,008B. Shared remote cache identities preserved and all foreign services/runners untouched. One metadata mismatch stopped first removal: initial audit git status created/removed index lock, changing only .git directory mtime. Exact reinspection/updated release retained; second revalidation matched completely. All capture artifacts/job logs are retained locally and on authenticated Actions artifacts. Three released local lifecycle executables deleted after exact SHA/inode/lsof verification (157,078,566B); source/binary receipts and all six samples remain. Final canonical/integration checkouts remain active through merged-file readback. Retired read-only nested baseline is released separately to sole cleanup owner with exact inventoried directory-write restoration only, surrounding evidence protected.
Final qualification 2026-11-12 19:02 UTC: TreeDB run43274393296 attempt3 completed SUCCESS, all40jobs successful; raw job131409805055 and required aggregate131416306602 successful. Hosted ubuntu-24.04 runtime Go1.26.11 linux/amd64 was identical before/after within each comparison. Artifact13974283098 (116747B) ZIP SHA2565b09288a5988d3d124ccfc128dbc777069bd07d57183c6aa1e44d0eb02500c91 authenticated; safe extraction and full source/base/runtime/harness/sample-binding audit passed. All five raw rows pass; PRIMARY fixed128/eightpairs accepted=true,quiet=true,92193→92193B/op,341→341allocs/op,0generation advances,pairedtime+1.019100%; Stats threepairs quiet=true,382861→382859B/op,1048→1048allocs/op,pairedtime−0.139191%. No thresholds/workloads/estimators changed. All raw samples and earlier adverse attempts retained; original +2B/op/Stats attribution is unresolved and#5191 remains open. This is qualification of dcc7 against cf4, not a claimed repair of the estimator or historical interleaving.
Final readiness: live head dcc7/basecf4 unchanged; non-draft, conflict-free. Check rollup56SUCCESS/1CANCELLED, the latter solely M0 optional post-job cache tail with independently accepted completed capture as documented above. Ruleset19140463 strict required TreeDB gate green; required human approvals0. Codex exact-head classifier clean, no unresolved Codex threads; only CodeRabbit thread resolved after explicit finding withdrawal. No requested changes. Exact-head policy readback complete. M0 cancellation is not relabeled green. Normal merge selected to preserve source ancestry; expected-head SHA guard required. PR body now records final qualification and accepted bounded public-lifecycle cost.
Retired baseline cleanup complete: exact nested baseline-main78e path absent/unregistered after inventoried owner-write restoration only; observed reclaimed1129349120B. All surrounding evidence/primary/canonical/integration/shared-cache identities and protected dirty statuses retained. Original67file recovery manifest remains zero mismatches. Seven local released worktrees plus three local benchmark executables and the owned remote runner root have been deleted; final canonical/integration release waits for actual merged-file readback.

All3local source refs are merged ancestry and all18other tags match live GitHub refs. No unique source bundle required. No further Git-store consumer/writer remains.
Closeout 2026-11-12: selected deliverable PR5373 accepted and completed at merge2590d1e9e443c3f968303ce91b3c82933a714f12. Related#5338 progress published and read back at #5338 (comment); it remains OPEN for the original first-Optimize error/historical Service4096 interleaving. #5191/#4519 and#5225/#5238 parent qualifications remain OPEN. No additional graph node is adopted by this completion.
Sole cleanup owner finished and stopped I/O. Both final canonical and integration paths are absent; canonical unregistered by ordinary no-force worktree removal before exact common-store clone deletion. Only allowlisted pyc was unlinked. The expected .git/worktrees/5373 registration, now-empty .git/worktrees parent, and containing directory metadata changes were recorded; no source or ref changes occurred. Protected primary/gomap-main dirty states, foreign worktree identities/registrations, surrounding evidence and shared caches exactly match release. Original67-file recovery ledger passes with zero mismatches. Final report /tmp/gomap-5373-authoritative-20261112/recovery/final-two-release/cleanup-report.json. Free30493794304B (28.40GiB). Persisted last deletion interval measured integration clone only: +1139433472B (1.061GiB); canonical1100224KiB predelete allocation is separate, not an observed combined gain. All nine released task checkouts, three local benchmark executables and the owned remote runner root have now been removed. Remote source branch absent after GitHub automatic deletion; source ancestry preserved in merged main. Other shared-store refs remain with their protected stores as recovery metadata; no global pruning/forced branch deletion.
No active owned writer, benchmark, watcher or cleanup task remains. Retained evidence index /tmp/gomap-5373-authoritative-20261112/closeout-evidence-index.json binds complete accepted/adverse artifacts, source manifest, final required CI logs, merge/main readback and cleanup receipts. Unique prior dirty work remains in the verified bounded recovery packet, not in disposable checkouts. Final acceptance owner: coordinator under the user's lease reset and codex-issue-graph-executor execute-and-merge authorization.

Current-head M0 failure retained: head dcc7d5b1ca4cb13abd3e0a7e86afb4160a358cd7, run43274393504/job131378816058, artifact13969867237, ZIP SHA256 849b2226dbc01dd2af1e6d98bc09b6944df03c114c992ec6f08f201158aac025. All ten original captures completed. Production/public availability passes with zero unexpected errors; total-vacuum CV0.0809 passes, foreground-p99 CV0.1332 fails0.10, pause diagnostic CV0.2300 requires owner review. No samples excluded and no threshold changed.
This matches the documented timing-stability recurrence in #4519; it does not establish the historical or current environmental cause. The fixture has zero leaf-log bytes, and the new cold-import path is not part of this backend-only benchmark. Under the executor's bounded recurring-CI policy, I am allowing one affected M0 rerun on this head, preserving this original failure. It may refresh the unchanged gate, but it will not establish a repair or close #4519. No already-green checks will be rerun; a second failure will be reassessed rather than retried again.

Qualification reassessment at exact dcc7d5b / base cf4ea68:
Both hosted M0 captures remain FAIL: original p99CV0.1332 and bounded retry0.1623 against0.10. The retry's vacuum-totalCV0.0159 passes; all ten original production/public samples finish with4096foreground operations, zero aborts/unexpected errors, unchanged fixture and positive production availability. Cause is UNKNOWN. No further hosted reroll is selected.
The current raw job passed all five raw rows. PRIMARY strict allocation bytes failed92122.5→92124.5B/op with340allocs/op unchanged and paired timing+1.309% passing. Source review found no explicit added heap allocation in this ordinary nil-maintenance-envelope path; compiler/frame effects remain unproven. Both-sign paired byte deltas and process-global counters match the class investigated by#5191 but do not prove the same cause. Stats is an unchanged timed formatter with input-dependent memory/RSS fields; its one-object discrepancy remains diagnostic.
Selected next proof: use the workflow's EXISTING administrator-selected, per-PR controlled Linux runner route. This materially changes infrastructure, not product, workload, estimator or thresholds. Host192.168.0.185 is reachable; actual preflight shows no active Go tests/builds, six physical cores, writable fast NVMe mount with123GiB free and23GiB available memory. Other services/runners remain untouched. Prepare one ephemeral runner restricted to CPU2,3 and a unique M0-only label, with original Go1.26.10/GOMAXPROCS2/GOMEMLIMIT8GiB and shared user Go caches. Run exactly one complete unchanged M0 qualification, retain its whole artifact whether red or green, then drain before any other measurement. A separate one-shot raw/PRIMARY refresh may use its distinct label after M0 releases the host. No blind retry, source intervention, threshold allowance or historical-cause claim follows. If controlled qualification fails, inspect its exact cause and reassess rather than repeat it. Temporary repo variables/runner and disposable outputs will be removed at release. #4519 and#5191 remain open; their full broader acceptance is not claimed.
Controlled-capture setup correction, before measurement: M0 attempt3/job131389011170 failed before fixture compilation, with inherited GOROOT=/home/mikers/.gvm/gos/go1.25 conflicting with the setup-go driver. No measurement samples ran. Its full log and artifact13971027062 (ZIP SHA25664609675cdf6e0281397cc28d0021efdc55b2a8272baa6bb548d92cd08ac7b80) remain retained. The ephemeral runner exited and unregistered. I will relaunch this single controlled capture with inherited GOROOT/GOTOOLDIR cleared, GOENV=off and GOTOOLCHAIN=go1.26.10 pinned; preflight now confirms both go env GOVERSION and compiler report go1.26.10. Workload, estimator, thresholds, CPU affinity2,3, GOMAXPROCS2/GOMEMLIMIT8GiB and all other services are unchanged. This is a causal setup repair, not another sampled-CV reroll. Current-head race shard7 has passed. CodeRabbit thread PRRT_kwDOIdn7C862woY4 was source-reviewed independently and resolved as unreachable: private staged-prefix validation precedes inherited-chain attachment; assigned-header materialization uses its effective basis.
Controlled M0 evidence audit at exact head dcc7d5b: attempt4/job131393423388 completed its capture and upload successfully; post-job cache save is still pending. Authenticated artifact13970703789 is retained and SHA256-verified: 2f05fc57946bcbb3afb8b5a49ddd2d7634abb1d451c6360c2b24a3c6d641856e. All ten original production/public runs and fixture digest42a8a8ef… are present, Go1.26.10/linux-amd64, CPU2,3/GOMAXPROCS2/GOMEMLIMIT8GiB, clean source. Unchanged v3 gates all pass: total-vacuum CV0.01084484 and foreground-p99 CV0.05034158, each against0.10. Every production sample completed4096 overlap operations with zero aborts, vacuum errors or exposure misses; public status is explicitly available with zero unexpected errors/exposure misses. No sample dropped.
Outcome-owner review of the diagnostic writer pause: median30.320ms/max30.895ms/CV0.00848 on this ext4/NVMe host. This differs from hosted latency, remains retained, and makes no cross-host absolute-latency improvement claim. The v3 contract has no absolute pause threshold and explicitly treats this metric as diagnostic; broader pause/runner qualification remains#4519. The earlier two hosted CV failures remain failures with unknown cause.
TreeDB's completed current-head aggregate job131395388974 confirms all normal/race/vet/getversioned/perf inputs succeeded; only MVCC_RESULT is failure. The one predeclared controlled raw/PRIMARY/Stats comparison will begin after this M0 runner and all post-job I/O release. No aggregate rerun or merge is authorized by this comment. Six retired local worktrees have been removed after verified unique-source recovery, reclaiming6.30GiB; primary and active checkout statuses are unchanged.
Explicit non-blocking infrastructure disposition, reviewed before cancellation: exact-head M0 attempt4/job131393423388 has successfully completed both Capture and enforce M0 evidence and Upload complete evidence packet. Artifact13970703789 and its SHA2562f05fc57946bcbb3afb8b5a49ddd2d7634abb1d451c6360c2b24a3c6d641856e are independently verified; all unchanged v3 predicates and required pause review are recorded above. The only unfinished activity is setup-go's optional post-job cache save of10,338,102,361 bytes, stalled at536,870,912 bytes for over6minutes. No test, benchmark or tar process remains.
Independent GPT-6.1Sol/high source/policy review confirms index-vacuum-m0.md requires completed samples/predicates and pause review, not cache persistence; TreeDB required gate has no M0 dependency. Under github-pr-mergeable's explicit non-blocking-CI disposition, I will cancel this owned cache-only workflow tail and drain its ephemeral runner. The workflow cancellation remains a cancellation, never a green result. Completed M0 validation is accepted from its authenticated artifact; no new capture or threshold waiver is selected. Earlier failures remain retained. The controlled raw/PRIMARY/Stats comparison and green full TreeDB required gate remain mandatory before merge. Shared caches and other services/runners will not be modified.

Private COW leaf packing can relocate collection roots while an acknowledged ColumnGraph rebuild is pending. The retained graph header then points to the old physical basis, so later materialization or checked Close can fail. This change transfers the producer's exact accepted transition into cache adoption and refreshes the affected headers, preserving immutable recipes, command identity, assigned LSN, capacity promises and held old views.
A deterministic regression also exposed a cold transaction whose privately imported catalog outlived a public vacuum's pager replacement. After validating the original logical dependencies, publication now imports from its supplied current physical snapshot when the pager or immutable SYSTEM root changed. Otherwise it reuses the original import, preserving dictionary and compatible raw-checkpoint behavior. Temporary and partial imports are released outside publication, with cleanup errors propagated. Moved dictionary-compressed catalogs without a qualified current reader refuse before ACK.
The accepted packing transition is captured before lock release. A borrowed maintenance envelope preserves the common finalizer's options size. Disk/WAL formats, finite limits, provenance guards and performance thresholds are unchanged. Documentation and CI discovery are updated; macOS vet uses bounded build concurrency.
Validation is bound to head
dcc7d5b1ca4cb13abd3e0a7e86afb4160a358cd7, integrated with maincf4ea6858cf3b64c63d9573dbba88072e1e98a79:84348ab32M0 capture and artifact upload completed successfully. Its optional 10 GB post-job cache upload stalled and was canceled after independent policy review; the workflow remains canceled, explicitly classified as non-blocking infrastructure cleanup. The completed M0 artifact supplies the validation. Diagnostic writer pause was reviewed and retained (30.895 ms maximum on the controlled host); no absolute latency improvement is claimed.
Six alternating fresh-process controls used the unchanged public 4096-record durable seed/Optimize/checkpoint benchmark, Go 1.26.10 on darwin/arm64, and full content/query/graph, checked Close and fresh-reopen assertions. Median time was 703.564→697.375 ms/load (1.421→1.434 loads/s), bytes 133,439,976→134,962,808 (+1.14%), allocations 692,239→692,078, and peak COW bytes 51,983,120 in both arms. Every sample is retained. Both sources show allocation bands with unresolved cause; this is no speedup or byte-parity claim.
Earlier failing correctness and cost/variability results remain retained in the authoritative execution checkpoint. The new regression proves its cold-bootstrap mechanism; it does not attribute the historical Service4096 interleaving or close the broader defect. Combined 100k/16 and strict durable-ingestion qualification remain with the parent graph.
