RE-VERIFY — cn650e partial contract qualification, 2026-10-06T03:13:52.475202+00:00

Log paging remains BLOCKED; this lane did not adopt its draft into the PR. Re-read https://github.com/CodexCoder21Organization/ContainerNursery/pull/650 with gh pr view <full URL> --json state,headRefOid,mergeStateStatus,statusCheckRollup,mergedAt and verify both recovery refs with git ls-remote before acting. This banner supersedes this lane's old speed-acceptance framing only; independent upload work and the earlier evidence below are preserved. Do not complete/archive this shared handoff.

The supervisor requested adopting the verified two-file page-cost cuts, preserving64 callers/25,000 rows/4 pages/256 retained readers/128 MiB/two processors, replacing the workload deadline with a deterministic carrier oracle and payload-derived per-page allocation guard, then ten local passes during a genuine build plus remote selectors. The original 30-second runner bound was to remain. The complete requested gate is not met.

Primary oracle proved fail-first by reusing the existing public test testRollingFileLogCapture_snapshotWhileVirtualClientsAwaitResponses. The brief's b02668fb is row ordering; the actual four-worker fix is https://github.com/CodexCoder21Organization/ContainerNursery/commit/105f8abcc8e5839b05413581d25984b9277bb3fe and the regression is https://github.com/CodexCoder21Organization/ContainerNursery/commit/67f22bea82aef6800d67db63b17b57482eb1f26f. Fixed workers PASS 6308 ms. Reverting only the four worker builders locally fails 3034 ms at the after-ready getTotalLines() call, with the existing 1000 ms lifecycle exception. Both clients hold their carriers inside synchronized socket reads, and their replies await a latch released only after snapshot/close. The mechanism is a virtual capture writer unable to execute its queued snapshot while both carriers are occupied; this forced comparison supports it without a throughput deadline. The source reversal was restored exactly and never committed. No separate 10-run carrier campaign is claimed.

Port validation: RowEncoding 14618 ms, HttpChunkBatching 20121 ms, LongRow 23886 ms PASS; SelectedRowReplacementMatrix FAIL 34923 ms at the unchanged 30000 ms runner bound. All sixteen expected cases printed and shutdown completed; its process was gone at dump collection. The revised ConcurrentClients also failed the runner bound (34808ms XML), although every exact row assertion/resource count/bulk-read guard and 256 preparation allocation intervals completed. Its phases printed startup 7743 ms/workload 20486 ms/teardown 339 ms; preparation maximum 1159152 bytes. These are observations, not successful test verdicts or a proven runner defect.

The draft guard starts after retained-reader acquisition and ends at verified snapshot acquisition on the synchronous request thread; bound is retained payload bytes + reserved page capacity×192 +256 KiB. It does not cover subsequent response encoding, and has not been demonstrated to reject every allocation-cut regression. It is therefore incomplete and must not be presented as the requested whole-response oracle. Reader/encoding implementation changes preserve full-SHA verification and existing selection/cursor behavior; no public interface or persisted contract changed.

The runner's installed bytecode shows a readiness-based per-test watchdog, separate startup admission, and dump collection after its verdict. No further server defect or exact cause of the two completed-body deadline results is established. No failing test was rerun for green. Changing only the workload clock did not establish the unchanged overall gate. The ten-run driver is preserved but never executed; local acceptance 0/10, remote selectors not submitted, no remote run id/pass counts claimed. Required PUSHED/local10of10/remote result line is absent.

Next steps: re-verify refs/state first; supervisor must scope the unresolved deadline diagnosis under the unchanged limit and complete the full-request allocation instrumentation before the draft can be adopted. Retain all counts, payloads, limits, exact row assertions and carrier ordering. Once the demonstrated mechanism is resolved, perform the originally requested ten local genuine-build cases and remote selector/API-page gate, then update only the still-open PR with the exact qualified head. Do not merge/enqueue/dequeue, deploy, restart, publish, or edit excluded repositories. Historical 7–9-second GC share is from prior cn650b reports, not a new measurement here.

No code from this lane was deployed or published; no PR was enqueued, merged, dequeued, or closed. No handoff was completed. All owned test/compile processes ended, source checkout is clean, and full local results and findings are recoverable at https://github.com/CodexCoder21Organization/ContainerNursery/tree/wip/cn650e-evidence-20261006/investigation-cn650e. Read its README and findings before repeating any experiment. The unused gate driver/wrapper are preserved as unqualified recovery tools; jars/caches/certificates were deliberately omitted.

RE-VERIFY — cn649d partial upload result, 2026-10-06 03:08 UTC

Upload qualification remains BLOCKED. This worker was assigned to finish https://github.com/CodexCoder21Organization/ContainerNursery/pull/649 by adopting the two verified fixes and replacing its host-calibrated concurrent reader test with a deterministic contract test. The actual PR stays OPEN at 26cd650666b4e87c0796d8c97427aa5626bb982a. Both Actions SUCCESS; required kotlin.build(remote) FAILURE at https://buildtest.kotlin.build/run?id=828c8a3c; informational kompile-remote-build FAILURE. Re-check the live PR and canonical test-results API; these are snapshot states, not a current-source passing gate. No accepted PR source or description was updated.

Free-port binding was already on the live branch at https://github.com/CodexCoder21Organization/ContainerNursery/commit/04435d6c959412073c478a17afb8998c571abcec, so a duplicate port commit was unnecessary. Streaming is commit https://github.com/CodexCoder21Organization/ContainerNursery/commit/2746971dfd56eec5749a75fc47f2ca90beff5873. It uses Ktor CIO multipart events and writes bodies straight to native staging, retaining native staging for injected storage; a regular-file java.io.tmpdir produces the fail-first HTTP500 on old source and HTTP201 after the port. ConfiguredDirectory13560ms and InjectedFileSystem15149ms both PASS on identical affected source. Abort-after-handler-entry still verifies native staging cleanup. Ktor's old generic parser spools larger files to default temp rather than keeping their whole payload in memory; the change removes that extra spool/copy and default-temp dependency.

The native-backed reader attempt is https://github.com/CodexCoder21Organization/ContainerNursery/commit/163e58301c7bc9caf24729df74e7fdfae2fad47f. Explicit staging-write, publication and saved-config gates replace two-processor scheduling: both readers must inspect old saved/runtime images during unfinished staging and before saved commit, then new saved/old runtime before runtime replacement, then new saved/runtime after response. All twenty uploads, two readers, 2MiB JARs, exact byte checks and ten-second socket limits remain. The test failed the existing30s scenario bound while scanning native files. The later memory-backed variant also failed upload0's socket read limit; a bounded public diagnostic additionally observed null entries in FakeFileSystem's unsynchronized mutable open-file list during concurrent source open/close. That variant is unsuitable. These findings do not prove a server switch defect or exclusively explain the earlier timing failure.

Acceptance remains 0/10 accepted consecutive local passes, no broken-switch mutation proof, no green remote selector result. The one remote submission used a fresh fixed clone at163e5830 and the100-file selector list. Its client hung in submitBuildChunked RPC and returned no runID. The local client was terminated only after that source became stale; no remote run was cancelled or resubmitted. Zero canonical results are claimed. No parameter increase, reader/count reduction, weakened assertion, retry-for-green, merge/enqueue/dequeue, service restart, deployment or Maven publication occurred. Owned local clients/helpers/JVMs exited and the final ps audit found none remaining.

Next: resume from the streaming branch and evidence; redesign and qualify the deterministic reader fixture, prove that breaking the switch fails, restore it, then complete ten consecutive local passes and the green remote selector gate before updating the actual PR and its why-first description. No precise deadline parameter change is supported by the current evidence. No deployment/publication/unmerged-live code was introduced in this lane. Paired log-paging records and blockers below remain independent and are preserved. Do not complete/archive the handoff.

Log paging remains BLOCKED; do not merge or complete this handoff. Verdict (c), salvage part. The reader-ordering fix is adopted. Performance acceptance is not met, and the lane is closing within its 150-minute bound with all partial source and evidence pushed. No timeout decision is pending. This banner supersedes older log readiness claims; independent upload-lane state below is preserved.

Reader proof: adopted-head OutputCleanupPrecedesDisconnect 7727ms, FailureCleanup HTTP+HTTPS 11699ms, BackpressureCleanup 10521ms; 3 PASS / 0 FAIL, once each. Public reader regression failed on the predecessor and passes with cleanup before Netty close. On final candidate it also passed2636ms. PR description was REST-PATCHed with actual state and cost model.

Final candidate functional gate: exact round-six54 selectors 54 PASS / 0 FAIL / zero retries, serial public test-runner execution, CPUs0,1, normal JIT without C1 cap,128MiB heap and unchanged30s limits. Complete names and durations: investigation-l2o/round6-serial-aec.json; driver review and child argv alongside it. Included OutOfOrderPayload11671ms, Levels5787ms, FailureCleanup5980ms, TailPaging5858ms, TruncateDuringOutput16316ms. This was warm build cache and is not cold-repeat acceptance.

Performance gate not met,0/6 complete. On850fa8f95998391529f4b5abe161f30c8e23d712 the cold five-run Concurrent sequence was18707,18735,17508,18465,21094ms. The fifth missed20s. Earlieradd5 sequence18450,21875ms stopped at its first miss. Finalaec Concurrent measured19038ms and explicit-file-selector20005ms with warm build cache. No failed result discarded, no rerun for green. The six requested5/5 cold sequences remain incomplete.

Cost model:64clients×4pages×25000rows=6.4M scanned rows/339.08MiB,1.6M selected rows/84.77MiB copied and full-SHA checked, and complete client field assertions. Payload remains1000×192KiB=187.5MiB. Candidate extracts parser/copy/file-set loops and avoids repeated fixture encoding/capture setup, redundant parse after identity equality, and temporary strings for exact expected values. Full SHA identities, snapshot verification and Netty termination remain. Minimal profiles show scanner, SHA, client parsing and late compilation; extracting the1392-byte copy lambda removed its long late C2 events. GC pauses were below1s; prior63EOF gates all released. Neither a permanent pipe hang nor one cause for every original victim is proven. These improvements do not establish the required margin.

Remote CI https://buildtest.kotlin.build/run?id=8ae8355c failed during chunked upload with one chunk and no assembled archive, separately from the original genuine paging failures. The only full-suite request https://buildtest.kotlin.build/run?id=95c5b335 submitted691tests on earlier850fa8f9. Client exited1 after its existing30-minute polling bound, last live statusBUILDING; watchman saw stalePENDING. No terminal result, zero-retry success or final-head qualification is claimed. The remote job may continue; it was not cancelled or resubmitted. Local client/watcher/test processes ended and reviewer completed.

Next concrete work: resume fromaec and the durable drivers; measure remaining Concurrent costs using minimal.jfc before a source-backed change, then prove all six cold5/5<20s gates. Resolve the existing remote run outcome, run the full suite once on the qualified final source, adopt only qualified changes into the PR, and obtain green required CI. No timeout/payload/count/assertion relaxation is authorized. No excluded repository edit, merge, enqueue, deployment, artifact publication, completion or release was performed. The challenge CLI's automatic merge conflicts with this lane, so tooling friction is recorded in investigation-l2o/challenge-report.md for the orchestrator.

Log paging is still IN PROGRESS; do not merge or complete this handoff. Reader fix is adopted at OPEN https://github.com/CodexCoder21Organization/ContainerNursery/pull/650 head 04deb39ba14c6061cfa207d4f1dc5a5cafb95bc6. Three cleanup tests passed once each. Required https://buildtest.kotlin.build/run?id=8ae8355c failed before tests because chunked upload stopped with one chunk and no assembled archive. Both Actions checks passed. This does not explain away the older genuine paging failures.

Performance checkpoint https://github.com/CodexCoder21Organization/ContainerNursery/tree/wip/l2o-paging-costs-20261005 is add5fe529b5f16d847c71f4c297cfc94301f4b13. Concurrent improved from 33.029s on initial combined production changes to 23.830s with the bounded retained-log fixture, 20.027s with separated known-string decoding, and 19.388s with the snapshot-copy loop extracted from its 1392-byte setup lambda. Intermediate expected-string reuse measured21.061s and cold20.416s; no isolated speedup claimed. Copy loop C2 compilation was observed at18.107–19.421s and19.665–20.782s on its predecessor. Full identity checks and every test assertion remain; independent source reviews found no correctness issue. First true cold-cache repeated acceptance is now running; none of the six5/5 gates is complete, and54-selector/full-suite gates remain pending. No performance source has been adopted into the PR.

Reader mechanism: producer catch closed the Netty context before outer page.use finally closed the snapshot and retained readers. The public HTTP test injects a read fault after actual client body bytes, holds protectedClose, and observes premature EOF on unchanged source. Closing page first flips it to passing, independently of every performance change. Context termination and suppressed cleanup failures remain.

IMPORTANT cache correction: scripts/test.bash injects its HOME-derived cache argument before caller args; the extra requested cache path was ignored. Earlier profiles used fresh JVM/JIT/fixtures but warm build caches. Repeated exact8b47 profiles in fresh clone paths confirm actual caches initially absent: ConcurrentClients FAIL33812ms, OutOfOrderPayload FAIL34414ms, taskset0,1, normal JIT,128MiB heap.

This upload snapshot supersedes the older upload readiness sections; separately owned log paging records are preserved below. Re-read https://github.com/CodexCoder21Organization/ContainerNursery/pull/649 and git ls-remote before acting. The lane made no production changes, merge, enqueue, deployment, artifact publication, completion or release.

The user's lane request was to reproduce an apparent remaining UDP failure on upload head26cd6506 before fixing it. That premise is refuted. Source metadata and extracted archive names identify the three cited runs as older informational evidence branches:

Run	Verified source commit	UDP listener source
https://buildtest.kotlin.build/run?id=f9961d93	https://github.com/CodexCoder21Organization/ContainerNursery/commit/5fecf0356f4432d13a0da4d3256e99840d31750f	`GlobalScope.launch` on Default

The current upload head is26cd650666b4e87c0796d8c97427aa5626bb982a, whose listener uses GlobalScope.launch(Dispatchers.IO). All four commits have the identical UDP test blob e3a42be3b35086589de38d6ac59960fc23195ea8. f996's actual selected result is SocketTimeoutException: Receive timed out at generated249/447, the first old-image request, duration17213ms. The other two selected rows currently remain RUNNING/error empty in incomplete projection; their alleged final failures are unverified.

Current head verification: 10/10 unchanged UDP selector attempts passed,0failed; body times11392,18079,20944,19878,22158,15972,14092,14437,15275,19236ms.

Every child confirmed2CPUs, tier4,128MiB and affinity0–1. First build cache cold; subsequent builds reuse artifacts, with fresh JVM/JIT/marker compilation/children/fixtures each time. Local JDK Temurin21.0.12.1 differs from CI OpenJDK21.0.11; shared6GiB cgroup differs from dedicated4GiB droplet. These passes are investigation evidence, not a new repair or full-suite/CI acceptance.

The actual required check targets current26cd and https://buildtest.kotlin.build/run?id=d0358012. Github check111726630304 is FAILURE:0passed/727failed, all unstarted tests marked Test did not complete during build execution, caused by the provisioning watchdog. Its output says last provisioning progress10:55:20.812 while quoting last log11:05:31 (droplet active); raw log later reaches SSH/guest readiness11:05:36. No test body executed. This contradiction needs investigation in the BuildTest provisioning/watchdog path, not a guessed UDP change. The watchdog owner is excluded BuildTestEmbedded (src/buildtest/embedded/BuildWatchdog.kt).

Read source audit, run identities and 10-test ledger.

Remaining upload action: excluded-repo scope. Orchestrator must route the required BuildTest watchdog/provisioning issue to an authorized lane and obtain canonical full-suite green CI on actual26cd before its merge decision. No ContainerNursery bugfix, timeout change, retry, assertion weakening, full local suite or production branch push is justified by these older failures. Lane stopped per the excluded-repository rule; no CI rerequest was issued.

Operational findings: initial500 HTML rows falsely claim all failures are included while projectionIncomplete/reconciliationPending; they omit the selected test. page=2&limit=500 API warming503 persisted; page=7&limit=100 recovered f996 exact row. Full raw log eventually recovered, but no selected failure output was in it. 0521/707 raw logs contained megabytes of ordinary dependency warnings; durable evidence retains their source-identity excerpts, not redundant raw warnings. Hardware Fabric certificates absent; no SSH fallback used. No production deploy or publish occurred.

RE-VERIFY — 2026-10-05T08:01:20.576756+00:00, round 7: deadline acceptance still fails

This replaces older PR650 readiness claims. Independent PR649/upload state below is preserved.

Both GitHub Actions checks were SUCCESS, required remote checks IN_PROGRESS at the final read. No CI watching/re-request, merge/enqueue, deploy or artifact publication occurred.

Measured mechanism: software SHA-256 twice over selected rows consumes 481/632 pre-output producer JFR samples and approximately 9 seconds before output. CRC32C plus exact row length removes that sampled cost (approximately 2.5 seconds preparation); cursor SHA-256 remains unchanged. However checksum-only payload durations were 27184, 14440, 19538, 15699, FAIL32483 ms; expanded output candidate FAIL33406 ms. Both preserve 192 MiB and the unchanged 30-second cap. The final deadline stack is a filesystem read during output; this does not identify the remaining walltime mechanism. No third speculative fix was made.

Correctness on the expanded candidate: RowEncoding PASS6252 ms; 16-cell replacement matrix PASS14780 ms; 24-cell truncation matrix PASS12820 and7811 ms; FailureCleanup PASS9252 ms; CursorGone PASS8565 ms; strict PASS10227 ms (workload6759.263404/startup1247.307576/teardown45.353341 ms). Total observed round-seven scenarios13PASS/2FAIL. Five-repeat focus sequence and full54 confirmation are incomplete; inherited53/54 is not candidate verification. Independent source/test reviews found no implementation issue; exact closing-tag wire assertion was added and passed.

Remaining work: diagnose residual output walltime with test-owned JFR file-read/GC/scheduling events and exact phase boundaries under the same restriction, fix the demonstrated mechanism, then satisfy five-consecutive payload, prescribed focus-five and54-selector acceptance; rebase and safely push reviewed source to PR650; orchestrator owns required remote CI and merge decision. Apply round-seven's evidence-only exit: do not treat these recovery branches as accepted fixes. No excluded repository changed. Read current refs before using either candidate.

RE-VERIFY — Upload round 7 at the orchestrator merge gate, 2026-10-05T06:03:36.031934+00:00

RE-VERIFY: this is a write-time snapshot, superseding all earlier upload state below. Re-read https://github.com/CodexCoder21Organization/ContainerNursery/pull/649 with gh pr view <url> --json state,headRefOid,mergeStateStatus,statusCheckRollup,mergedAt and verify git ls-remote before acting. Separately owned log work and its blocked reason are preserved unchanged.

The user asked for complete JAR uploads at fresh paths that switch only the selected route image. The upload lane has finished round-7 findings 1–8: native dangling/relative/chained/cyclic/ancestor backslash identity; drive-like target/parent/missing-file identity; upload/socket/acquisition cleanup ownership; real RPC listener port-zero ownership; TCP/UDP public server-receipt proof before held replacement release; and real-child termination with ten-stage primary-plus-suppressed/actual-reader-failure coverage. The cleanup-matrix timing failure came from repeatedly launching separate javac JVMs for later fault stages. Those stages still compile real source through the owned executor and scoped JDK compiler/file manager, while blocked-start and external-exit process stages remain; no bound, count or assertion changed.

Verified: 86/86 selectors passed, zero failures, at fe3fd5eae3436aef23a38c1ae179e2efd205f585; the continuation checked the exact81+5 ledger and every successful scenario/build-rule XML. Final fetch/rebase was a no-op. 4/4 final selectors passed, zero failures, at b5e942a1e0bd75e3d3c4347ebd9dd232a0b1a862: testDanglingBackslashSymlinkUsesNativeIdentity, testJarListingPreservesDriveLikeParentSegments, testVersionedUploadKeepsTcpRuntimeRouteVisibleDuringReplacement, testVersionedUploadKeepsUdpRuntimeRouteVisibleDuringReplacement. Final production/build/script objects match the accepted86 head; delta is one explanatory comment and two whitespace-only test lines. Historical18/18 Gradle methods at 88f1d7d80ed528712dc247b609e910240e11e094 were not rerun under the overriding targeted-only continuation. The prior independent reviews and their addressed findings are preserved in the evidence.

The binding continuation ruling places Okio FakeFileSystem3.4.0's drive-like-symlink NullPointerException (lookupPath:518, recursive call :554) outside this round. Production native cases pass; injected cases use inputs the fake can represent. Both extra untracked probes were deleted and the native-only case-list comment cites that limitation. No dependency patch, fork, shading or symlink-resolution wrapper was added; no Okio work remains assigned to this lane.

Complete86-selector ledger and final4-selector ledger name all tests, heads and outcomes. Latest single post-push PR read saw Gradle and release-package checks IN_PROGRESS; kotlin.build (remote) was absent from that rollup, so this lane makes no CI-green claim and starts no watcher or rerun.

Remaining upload action: orchestrator re-verifies the final head, completes its own review and required remote CI, then makes the merge decision. No lane enqueue, merge, deploy, Maven publication, handoff completion/release or excluded-repository changes occurred. No production code was deployed or published by this continuation.

RE-VERIFY — Upload round 6 merge gate, 2026-10-05T02:34:25.975252+00:00

This section supersedes historical upload rows only. The separately owned log lane and all historical evidence below are preserved. Live upload PR is OPEN/unmerged at 88f1d7d80ed528712dc247b609e910240e11e094. This lane owns only https://github.com/CodexCoder21Organization/ContainerNursery/pull/649.

Findings 1–10 are implemented and independently reviewed: unchanged-transport URL registration is retained with current per-request push generation; resolved native backslash target identity is preserved; config replacement preserves original POSIX bits including read-only modes; native/Fake cyclic/dangling/non-directory target listing agrees; real HTTP/HTTPS/TCP/UDP/URL dispatch and explicit intermediate snapshots cover complete route replacement; component restart restores persisted authentication/configuration/notes/arguments and unrelated routes; guarded setup and independently reachable teardown cover all opened fixture resources; ordinary Okio listing avoids redundant native enumeration.

Three unchanged adopted probes fail at the previous candidate and pass after fixes. Additional fail-first evidence covers cycles/directories, backslash image history, umask loss, read-only staging-open failure and non-directory ancestors. All original scenario names and core assertions are retained. Coverage additions that test already-correct existing behavior were not made artificially red.

Verification: 81/81 targeted kompile selectors accepted, comprising all 69 previous selectors plus nine new/adopted scenarios and three URL bridge neighbors. 18/18 selected Gradle methods passed, zero failures/errors/skips. Only targeted local commands, one at a time; no full suite. No timeout increase, stress reduction, excluded-repository edit, CI request/watch, merge/enqueue, deployment or artifact publication.

Fixture adaptations: the real UDP child binds UDP before a TCP readiness listener on the same PORT, so its JAR launch uses the actual TCP readiness seam while dispatch uses the real UDP facade. Restart uses public persisted ConfigManager route reads and full component rehydration; the CLI rejects the deliberately ephemeral configured port zero and was not changed. Cleanup uses small ordered actions to preserve primary and suppressed failures without exceeding the JVM method-size limit. Full failed fixture attempts remain in the evidence.

Remaining: Required remote CI, orchestrator review and merge decision.

All five round-four findings closed within this lane: (1) selected provider pruning now preserves the original-view page, then gives complete410 on gone continuation; (2) every valid native severity is included for each single/multiple public level; (3) warm-up/startup/workload/teardown are separated, workload retains30000ms and all counts/heap/guards, strict20 maximum below15000ms; (4) global timestamp-group occurrence/prefix proofs avoid rebinding disjoint identical rows; (5) real writer rotation is positively observed while a public page holds an opened read view. Provider proofs retain bounded selected-group state; file opened/byte-bounded view and interchangeable-identical-content contract remain.

Tests:46targeted PASS/0FAIL (inherited42 plus testCloudRunProviderSeverityFilters, testAdminLogsCaptureRotationDuringTraversal, testAdminLogsProviderPruneDuringProof, testAdminLogsProviderDisjointIdenticalRows), then20strict PASS/0FAIL, all at the verified source head. Baselines failed before fixes: prune500, disjoint expectedafter/actualmiddle, INFO expected3/actual1.

Phase	Min ms	Median ms	Max ms
warmup_ms	62.337	97.927	193.447
startup_ms	825.873	1200.676	2920.612

teardown_ms	32.138	60.537	141.970
reported_scenario_ms	6630.000	9713.500	13750.000

The workload maximum9333.621ms is3.21x below the unchanged30000ms deadline; reported whole-scenario maximum13750ms is also below15000ms. The original runner function guard remains unchanged; setup/teardown are not claimed to be excluded from that general guard. Timing measurements/new workload bound isolate concurrent paging work. No timeout, iteration, client, row or heap change.

Prominent fixture workaround: SDK3.22.0 local-host construction closes its transport before the first request. The test uses the supported SDK RPC factory, real local gRPC server/channel, complete request filters and14fresh/closed clients; no live Google call and no external SDK fix/publish. Two helper-layout validation failures and two SDK setup failures preceded the actual native-filter baseline; these are not counted as behavioral proof. Full stacks are in the evidence snapshot.

Remaining only: orchestrator-owned kotlin.build (remote) green check, final review and merge decision. This lane stops at that gate; do not infer permission to enqueue/merge/deploy. No excluded repository was modified. Older snapshots below are historical, not current source/readiness.

RE-VERIFY — L2h round-four checkpoint 2026-10-05 00:04 UTC. This section supersedes older PR650 readiness claims; PR649 remains independently owned.

PR650 is still open at original head9bdabe0ff334116f64848bed5d62cb0689061dac until the final campaign completes. Recovery source https://github.com/CodexCoder21Organization/ContainerNursery/tree/wip/l2h-round4-20261004 is now550d489c2fb1aec93b5ec9a2ee5bed8250f66c34. Provider prune/disjoint probes failed first and pass after original-view bounded proof retention; active writer rotation passes both transports; native severity baseline INFO expected3/actual1 now passes complete inverse mappings at5227ms.

Remaining: final46-targeted and strict20 phase campaign, final rebase/push/PR body, orchestrator required remote CI and final review. Timed workload alone keeps30000ms; startup/warm-up/teardown are measured separately, original runner guard remains unchanged. If workload max>15000ms, report evidence for the orchestrator decision rather than optimize or alter limits. SDK local-host constructor closes its channel before reading; test fixture uses supported RPC factory with a real local server/channel, no live Google call. Recovery/evidence preserve work; no merge/queue/deploy/publish/CI rerequest.

RE-VERIFY — Round-four log paging, 2026-10-04 23:35 UTC

Write-time snapshot: re-check https://github.com/CodexCoder21Organization/ContainerNursery/pull/650 using gh pr view <url> --json state,headRefOid,statusCheckRollup,mergeStateStatus and re-read remote branch SHAs. This section supersedes earlier log readiness claims only; all independently owned upload records below are preserved.

The fourth-round brief requires provider selected-content pruning, disjoint identical-row occurrence proofs, complete native Cloud Run severity filtering, active-traversal rotation coverage and separated strict-workload phase accounting. Baseline probes at9bdabe0f failed deterministically: HTTP500 after provider pruning; forward continuation returned middle instead of after for disjoint identical rows. Full raw stacks are on the evidence branch below. Provider pages now retain bounded selected-timestamp proof state from their original traversal rather than refreshing it. Expanded HTTP/HTTPS forward/tail prune first/continuation scenario passes1/0(4995ms); expanded disjoint unchanged/appended/pruned scenarios pass1/0(3402ms). Source checkpoint is371f4525. Severity fixture/fix, active rotation scenario and42+new+strict20 final campaign remain in progress; no final readiness claim.

The orchestrator owns required remote CI, final review and any merge decision. No CI watch/request, enqueue, merge, deploy or publication; no excluded-repo edits.

RE-VERIFY — Upload round 6 checkpoint, 2026-10-04T23:34:48.837580+00:00

This section supersedes earlier upload rows only. Preserve separately owned log and CI records below. The upload PR was live-read OPEN/unmerged at c2d780692ab09722f3d2c7ec7d09f97b196fa358; it has not been pushed by this lane yet. Required remote CI and merging are orchestrator-owned.

Round-6 baseline probes fail on the prior implementation: URL advertisement withdrawal, native backslash-target metadata/history, config 0600 replacement and native/Fake cyclic-link parity. The first fixed owner-only permission, URL and backslash probes plus listing/cyclic/history matrix pass. Broader permission testing additionally proves creation attributes lose group-write bits under umask 022; that correction is being tested. Started HTTP/HTTPS/TCP/UDP/URL dispatch and complete persisted-config restart/hostile cleanup fixtures are under review. No timeout or stress count change, excluded-repository edit, CI action, merge/enqueue or deploy.

RE-VERIFY — Log paging round-3 verification, 2026-10-04T22:26:45.971198+00:00

This is a write-time snapshot. Re-check https://github.com/CodexCoder21Organization/ContainerNursery/pull/650 with gh pr view <url> --json state,headRefOid,statusCheckRollup,mergeStateStatus and re-read remote branch SHAs before acting. This section supersedes earlier log-paging rows and readiness claims only; separately owned upload records below remain preserved.

The latest brief assigned one verification of the existing candidate, with no further optimization. Candidate 9bdabe0ff334116f64848bed5d62cb0689061dac rebased unchanged on origin/main (dab37c7890cb8787c3ea767219ed0ad8bccb1ea5). All 42 targeted scenarios passed / 0 failed, each once, followed by 20 strict runs passed / 0 failed, serially on that exact head. No source changes were made in the verification lane. A normal fast-forward push updated the actual PR branch, and the WHY-first round-3 PR body was applied and read back.

Cursor proof uses one consistent content view rather than an index from another traversal. Append-between-traversals, file append/physical rotation, provider forward/tail continuation, identical replacements and exact HTTP/HTTPS 410 for vanished content all passed. Positive-first real-socket backpressure, bounded-row/parser/allocation/cleanup/provider cases and corrected public docs are included. This does not claim every request performs only one traversal: nonmonotonic timestamp ordering can require a fresh outgoing content proof, as documented.

Strict workload remains64 virtual clients × 4 requests × 25000 rows, default 128MiB,2 processors and original 30s deadline. Durations in ms: [18262, 15196, 15957, 12708, 18732, 23304, 20516, 18157, 12703, 16103, 17268, 14993, 11332, 11834, 12851, 14781, 15694, 19803, 14349, 16585]. Min 11332, median 15825.5, max 23304; reported headroom 6696ms (22.32%). Prior 9f candidate20/20: min8362 / median13906.5 / max20425ms. The current median and maximum are higher than that predecessor and exceed the earlier 15s goal; no timing-improvement claim against it. The latest brief accepts current margin as review input and prohibits further optimization. Large-payload case passed 18934ms against inherited 32780ms failure. FailureCleanup was runner SUCCESS with XML 30507ms, retained prominently rather than omitted.

At the final current-head snapshot, Gradle and release checks were IN_PROGRESS; kotlin.build (remote) was absent from the rollup. CI is not claimed green. The orchestrator owns required CI, final independent review and merge decisions. No CI watch, request or rerun, full suite, merge, enqueue, deploy, Maven publication, excluded-repository edit, handoff completion or release occurred.

Next: re-verify current refs, run orchestrator-owned remote CI and final reviews, then let the orchestrator decide whether to merge. No further verification-lane optimization is pending. Raw proof: https://github.com/CodexCoder21Organization/ContainerNursery/tree/investigation/l2g-round3-verification-20261004/investigation/l2g . Reproduce a selected case with JAVA_TOOL_OPTIONS=-XX:ActiveProcessorCount=2 scripts/test.bash --local --test <name> --log <path.xml> under its unchanged deadline; do not start another campaign just to obtain different timing numbers.

Operational note: the predecessor-established structured REST PATCH route avoided the installed gh pr edit projectCards issue. Its immediate response reported the old PR head despite the new git ref, but a fresh final snapshot confirmed 9bdabe0ff334116f64848bed5d62cb0689061dac and the exact intended body. No source or test workaround was introduced. No production state was changed or newly published by this lane.

Upload fifth-round source checkpoint — 2026-10-04T22:17:00.788341+00:00

RE-VERIFY: https://github.com/CodexCoder21Organization/ContainerNursery/pull/649 was re-read before the fast-forward push. Latest upload source is c2d780692ab09722f3d2c7ec7d09f97b196fa358 on https://github.com/CodexCoder21Organization/ContainerNursery/tree/wip/upload-versioned-switch. This section supersedes earlier upload checkpoint rows; earlier round records below are historical. Preserve every separate log-lane/CI record. No merge, enqueue, deployment, publication, completion or release is authorized by this checkpoint.

Both assigned findings are addressed: configured routes stay visible during image replacement, and ordinary native/injected storage shares the Okio path. The adopted snapshot, real HTTP reader and persisted-config restart pass, with additional real-provider TCP/UDP/URL snapshots. Native/Fake linked-image metadata/deletion is covered. A shared-clock retention fixture found during the requested gate was deterministically reproduced and repaired without changing production retention code or weakening any existing assertion/deadline.

Final source verification: 69 targeted scenarios passed / 0 failed, 18 selected Gradle tests passed / 0 failed / 0 skipped, and the repaired retention fixture 20/20 passed after 10/10 baseline failures. The first 49 selectors ran at 7e8f6a31 and the remaining 20 plus Gradle ran at the final head after two explicit fixture imports; production and the first 49 test files are unchanged. Independent test/code reviews and the separate retention review are resolved. Evidence with full names, counts, logs and review: https://github.com/CodexCoder21Organization/ContainerNursery/blob/55434aa5824660294ff31cab8f09865d8d8447e4/round5-candidate-evidence/findings.md .

Unconditional native-branch deletion is narrowly refuted: Okio changes legal native backslash filenames and does not expose exclusive hard links/directory sync. Only these identity/publication operations remain native; ordinary configuration and upload I/O uses the same supplied Okio implementation on both stores. No excluded repository changed.

Remaining: orchestrator final review, required kotlin.build (remote) verification, and merge decision. This lane did not watch or request CI. Current CI snapshot is recorded separately in the lane's final report; this checkpoint does not claim remote CI green. Separate log-lane work below remains owned by its lane.

Upload fourth-round correction checkpoint — 2026-10-04 18:53 UTC

RE-VERIFY: https://github.com/CodexCoder21Organization/ContainerNursery/pull/649 is OPEN/unmerged at a5da1c2fa1d6ee082708c7aff122878e68ccc2c4, fast-forward pushed after re-reading the live old head and a no-op rebase on current main. This section supersedes earlier upload-source checkpoint rows. It preserves the separate CI investigation and every log-lane record below. Do not mark the broader handoff complete or merge from this checkpoint.

The six assigned fourth-round findings are addressed: native path identity, supplied filesystem use, exact accepted filename preservation, exclusive legacy/admin rollback ownership, bound-port fixture ownership and complete HTTPS409Conflict response. Six adopted public probes failed first, together with additional baseline scenarios0passed/14failed. Final exact-head targeted gate60passed/0failed includes all38prior selectors,19new scenarios and3neighbors. Only the three changed Gradle fixture classes executed:18passed/0failed/0skipped. Independent test-comprehensiveness and separate adversarial reviews of this round's changes are clean. README/API contract docs are updated; no test deadline/count/assertion was weakened.

Still pending: required kotlin.build (remote) is absent in the18:50UTC current-head rollup; Gradle/release checks are IN_PROGRESS. CI is not claimed green; the orchestrator owns its watcher. A separate investigation newly reported a runtime route-mapping visibility defect at the old5acb05e5head,5/5 deterministic failures. Its probe was outside this lane's six listed findings and was not run here on the new head. Preserve and assign that concern before merge: https://github.com/CodexCoder21Organization/ContainerNursery/blob/9ee11c0703642676ebc21f007d049c2e229d343e/investigation/r649ci-20261004/findings.md . This checkpoint is completion of the assigned round4corrections, not a claim that the PR is merge-ready.

RE-VERIFY 2026-10-04 18:08 UTC (R649ci investigation only): classification at exact upload head 5acb05e52cb5832c7979b2747069bc399b084283 is complete; upload source corrections remain with their owner. The broader handoff is not completed. This section adds investigation evidence and preserves all other active lanes' latest records below.

Upload required-check failure investigation

Upload PR was verified OPEN/BLOCKED at 5acb05e52cb5832c7979b2747069bc399b084283 at 18:02 UTC. Required remote run f3eee93f remains FAILURE; Gradle/release SUCCESS, informational kompile check NEUTRAL. This lane performed no fixes, PR changes, CI requests, merges, deployments or publications.

The requested 17 raw final-failure rows differ from authoritative check accounting: five are authoritative PASSED, and zombie repeated-crash restart is authoritative FAILED despite its last canceled attempt. Authoritative total remains 675 passed / 13 failed / 688. The complete 17-row classification and final report preserves paths, history, counts, full failure output, and limitations.

One PR defect is reliably reproduced: upload saves the new image, then runtime replacement removes the old facade mapping before adding the new one. A public getRoutes reader/re-entrant dependency callback can observe the configured application route missing. The original HTTP reader exposed this once in five isolated attempts. The deterministic real HTTP/ConfigManager/facade scenario fails at that exact assertion 5/5, at 12.2/6.9/9.3/6.4/5.3 seconds, with unchanged default 30s. Both upload endpoints use the same runtime replacement, but this is not proof the mapping gap caused their original CI gate/cleanup waits. Adopt the scenario only, not the investigation artifacts.

Original-script isolation: 37 pass / 3 fail over 40 runs (HTTP readers 4/1, HTTPS readers 3/2 cleanup waits; rollback, management, cold-start, stdout, idle-TLS, passthrough each 5/0). Genuine two-instance pairs: 11 pass / 1 fail over 12 runs. The paired failure is the same idle-TLS 10-connection control assertion at 1081ms, observed on unrelated prior branches. Every pass confirms 1/1 selected test executed. No test timeout, iteration count, assertion or payload was weakened.

Remaining upload-owner work: address the public runtime mapping visibility contract, run this fail-first scenario against the correction, then obtain current required CI and orchestrator review. Investigation lane is stopped at the requested handover, with final RUNNING report for the orchestrator's gate; it did not complete/release the handoff.

Qualifications: exact-test recurrence was verified from 54 recent CN runs; three unchanged tests have no earlier exact failure and remain unproven starvation candidates (request-target, URL EOF, concurrent log rotations). CPU admission's OBSERVE mode explicitly admits estimated demand above declared 2000-millicore capacity, with high aggregate runqueue waits and fixture/startup stacks. Those counters are not literal main-thread pauses. Scheduler/resolver mechanisms require their owners; BuildTest*, kompile*, UrlResolver and UrlProtocol modifications are excluded here. No guessed downstream mitigation is proposed.

Tooling findings: a fresh CLI body read hit its 60-second client bound; bounded JSON retrieval then succeeded. The latest body was preserved for this prepend. A paused supervisor inflated management run-1 command-wall accounting; actual test outcomes, not that wall value, are used. Full details are in the report. Both checkouts are clean; all test/probe background processes were audited terminated.

Log lane third-review checkpoint — 2026-10-04 18:00 UTC

RE-VERIFY: Actual https://github.com/CodexCoder21Organization/ContainerNursery/pull/650 was OPEN at76c272a8a49392ef041c86297118e5b918a8991c at lane start; this lane has not changed its branch. Orchestrator owns required remote CI; no watching/rerequest here. This section supersedes earlier log-lane readiness claims, while upload remains separately owned.

Third reviews require a provider append cursor fix, strict20 maximum under15seconds with unchanged64×4×25000/128MiB/two processors/30second limits, positive proof of backpressure in its regression, and correct archive work docs. Append defect is verified by reviewer's exact-head0passed/1failed first200/continuation400; local adopted baseline compilation ended at launcher300s before scenarios, so no own verdict claimed yet.

The universal exact-row continuation requirement needs a record-identity decision: current LogLine exposes only timestamp, level, message and CloudRun mapping discards entry identity. Retained boundary row plus append and pruned boundary plus identical replacements can expose exactly identical current rows and cursor, while the mandated responses differ200vs410. A public two-world regression is checkpointed; no guessed fingerprint relocation or generic400 fix has been written. Decision pending: persist/expose stable IDs in capture/provider record contracts, or expressly revise legacy identity-less semantics. This is independent of the known absolute-index drift, which remains real.

The WHY-first PR description contains all twelve review findings, exact counts/durations, preserved baselines and qualifications. gh pr edit's Projects classic query failed; structured REST PATCH applied the same body and readback verified its footer. No product artifacts are committed.

Remaining log work: required kotlin.build(remote) on this current head, then orchestrator final review/merge decision. The current suite100810928168 is queued with zero check runs (created16:52:21UTC on recovery ref); actual PR synchronized17:12:26UTC. No current-head remote run id/full-suite pass. Old-head provisioning failure and direct full remote upload failure are historical, distinct evidence. A bounded read-only watcher is active; no CI rerequest/warm/delete/comment or bypass. Stop at the owner gate if missing45minutes after actual PR push.

Traversal qualification for review: nondecreasing chronological histories use one full selection scan plus selected reads. Other ordering uses an additional scalar outgoing prefix/count proof. The literal universal one-pass ruling is refuted for arbitrary repeated unordered timestamps under the existing cursor contract without adding an index or changing the cursor; exact provider traversal counts expose it. Retained memory is bounded by page plus one row. Do not silently claim all orderings are one-pass or that the preferred half-deadline timing target was met.

No merge, enqueue, deployment, Maven publication, excluded edit, handoff completion or release. Final report will remain RUNNING at the orchestrator gate as instructed.

Pure in-memory config and sequential admin/legacy ownership scenarios added. Three Gradle listener fixtures now own bound ports; TLS status assertion added. No production fixes in this checkpoint. Plan: finish baseline proof, repair native/injected path identity, exact accepted filename and admin legacy ownership (copy movable legacy bytes to a fresh image under legacy/config lock order), run previous 38 selectors plus new cases, push actual PR after re-reading its head, park at orchestrator review. No CI rerun or watcher started.

Current log-lane checkpoint

Six production review fixes and five coverage additions have public fail-first/fixed evidence. Additional deterministic allocation guards remove row-filter iterators, selected singleton metadata and canonical row decoding during zero-match metadata scans. Provider fetches are bounded and errors propagate; all archives are scanned, physical rows are bounded, output suspends under backpressure, and request cleanup is tested on failure/disconnect. The strict client retains all four row fields, duplicate/order checks, full EOF and all256read guards.

Strict margin remains OPEN. The previous integer-reader gate ended6passes/1deadlinefailure (34539ms reported total), and earlier gates were also unsuccessful. Current exact-head gate at1db98273c71b967a065226dac9e00be5045ec0fe is 13/20 passing so far; durations(ms)=[16836, 11190, 11709, 12994, 10260, 18771, 9748, 9867, 16832, 10110, 22672, 16355, 20391]. Never call it20/20 until complete. Setup still writes25000rows and drains every200writes through the same public writer snapshot; zero-row reads avoid125growing history recounts, with the final full count retained. Query counts64×4, row counts25000,128MiB and30s are unchanged.

Required old-head remote failed during provisioning before tests; direct full-suite remote upload failed before dispatch. No full-suite pass or green CI is claimed; zero CI rerequests. Literal one-traversal proof for arbitrary unordered history is refuted under the existing cursor prefix/count contract: a second scalar edge proof is needed without retaining every timestamp or adding an index. This interpretation is explicitly awaiting final review. No excluded-repo edit, merge, enqueue, deploy, artifact publication, completion or release.

Both independent reviews required twelve findings to be addressed. All remain pending except the archive bug now has a confirmed public fail-first baseline: testAdminLogsRetainedArchiveRange, 0 passed / 1 failed, expected retained middle row but endpoint returned empty while storage getLines finds it. No production fix has been applied yet. Sparse-level, backpressure/disconnect and reader-failure public scenarios are checkpointed for baseline testing.

ContainerNursery log paging: source and strict gate complete; required remote CI still missing

Written 2026-10-04 12:35 UTC. RE-VERIFY: This update is authoritative only for https://github.com/CodexCoder21Organization/ContainerNursery/pull/650. Recheck its live head, remote refs and check runs before acting. The upload PR is owned by another lane; its older states below are historical, not this lane's verification. No merge, enqueue, deployment, Maven publication or handoff completion occurred.

Verified log-paging state

PR https://github.com/CodexCoder21Organization/ContainerNursery/pull/650 is OPEN at 0c5ed55a1bd0eef0f685fc8df653ff5bd8a4f809, fast-forward pushed from b02668fb6625fbd2d432456a00a90fac46c18a5f after checking the live head and rebasing main. The unchanged strict public scenario now passes 20/20 standard local-script runs, with 64 virtual clients, 25,000 rows, four pages per client, 256 exact file-reader opens/closes, 128MiB, two processors and original 1000ms snapshot / 30000ms test bounds. Reported scenario times are 11184–28995ms. One run remains close to the bound; no universal timing margin is claimed.

The JDK chunk allocation experiment in the earlier snapshot is context only. No JDK repository/runtime was modified by this continuation and no runtime patch is required. The ContainerNursery test harness previously drove actual chunked HTTP inputs through readiness probes, and JSON parsing locked the decoder once per character. A real public-endpoint 1,336,368-byte response fails first with179 readiness probes; a second fail-first assertion observes1,315,889 single-character decoder reads. Fixed byte refills remove readiness probes and single-byte body reads; request-owned character blocks preserve parser lookahead without per-character decoder calls. Every row, UTF8/escaped content, metadata, allocation bound and EOF are verified. The existing server writer is already buffered, and a separate real public raw-HTTP chunk batching test passes; no speculative server buffer change was needed.

Independent test-comprehensiveness and source review passes are recorded in the evidence findings. Final PR source contains only the public tests/readers added in this continuation; diagnostic logs and profiles are preserved on separate evidence branches.

Remaining log-paging gate and concrete next step

At12:29UTC, required kotlin.build (remote) has no check run on the final head. GitHub suite100765497229, app kotlin-build-ci-test, is queued with latest_check_runs_count0, last update12:15:21UTC. Build-watchman confirms sampled main suites did dispatch, making this a missing-dispatch signal; the receiver's exact failure mechanism is not yet established. bld-build-release is SUCCESS; Gradle was in progress. A direct final-head full-suite remote client returned no result/run id in roughly18minutes; its main stack at RemoteBuildWorkspace.execute:166 is preserved. The local client and watcher are stopped at this orchestrator action gate; no remote run was deleted. No full-suite pass is claimed.

The orchestrator, as single CI rerequest owner, must inspect/re-drive the missing suite once per watch-build's dispatch procedure and verify a new run/check exists, then get the required remote check green and review the PR before its merge decision. This lane has not rerequested, rerun, deleted a run or bypassed any check. The brief permits a documented /rerun only for provisioning/upload failures, and no applicable documented convention was found. No source change in an excluded repository is established as necessary. PR649 remains entirely with its upload lane.

The new writer/platform-thread and lower-allocation paging product is on PR650, but the prior20-run gate failed9passes then30s termination. L2's unchanged-time diagnostic copy also fails30s. It proves the64-party EOF barrier releases at2.88s, all64 first responses arrive by1.289s, and later pages remain in progress at cancellation. Paired20s/27s failure-time platform/virtual dumps are saved remotely.

A JFR public-scenario profile now identifies a large client allocation path: JDK ChunkedInputStream.processRaw line364 repeatedly allocates exact-size decoded buffers. A separate public HttpURLConnection/real loopback HTTP probe demonstrates the nonlinear growth,25.69MB allocation for8KiB already-arrived payload and126.96MB for16KiB. Its allocation assertion fails first. A diagnostic java.base patch using geometric growth flips it to passing with450.8KB/909.6KB and identical bytes/count/EOF. The unchanged original CN scenario also passes1/1 in15.537s with that patch. This is not a20-run verdict and does not yet prove every historical deadline cause. No runtime was changed globally and no consuming source was altered to avoid the upstream defect. The user's existing JDK fork has been located for an upstream source/test fix; remaining runtime adoption and CI ownership may need orchestrator coordination.

Exact Ktor 2.3.7 and Netty 4.2.10 source was inspected from official Maven source jars.

Evidence and ruled-out hypotheses

The mechanism is not completely established, and the evidence is the full platform/coroutine failure-time stacks plus public channel/executor counters: they identify active phases and a temporary buffer wait, but not one demonstrated sustained owner/queue explaining all failed requests. No allocation-cost or host-slowness explanation is claimed.

The previous remote run c9b53217 failed on its first upload; first app-route remapping appeared after HTTP teardown started. Fresh baseline isolated test passed 16199ms. Five simultaneous standard invocations failed the outer 30-second scenario limit after many uploads, a distinct verdict from a single 10-second socket read failure.

Twenty genuine simultaneous public scenario calls with original production and original 128MiB/C1/ActiveProcessorCount=2 flags yielded 17/20 first-upload SocketTimeoutException failures, receiving zero response bytes. All 17 later reported multipart Unexpected EOF: expected 4096 more bytes during teardown. This error after client close does not establish wrong byte accounting. Full getAllStackTraces was captured before cleanup. The older direct screens bounded whole-JVM runtime at 30s, stricter than the runner; outer-deadline exits in those screens are diagnostic, not phase gates.

Public kotlinx-coroutines-debug captures show RequestBodyHandler.copy suspended in ByteBufferChannel.writeFullySuspend waiting for request-body capacity while AdminContainer.handleUploadJar was in Reflection.typeOf metadata initialization from receiveMultipart. Other failures had already reached multipart/body parsing or publication. Replacing receiveMultipart with explicit non-generic TypeInfo removed the metadata path but still failed 14/20 without agent and 19/20 with agent; this experiment is rejected as a complete fix and original production was restored.

Latest drivers start Future.get(30000ms) at public scenario invocation, matching the standard scenario deadline. Ten concurrent original-production invocations with public progress observation produced SEVEN socket failures (runs 1,4,5,6,7,9,10) and THREE full passes (2,3,8). The earlier eight-of-ten note was corrected. Counters advanced near the deadline; run7 read 33158 ->377222 ->708998 ->1237390 ->2081166 ->2097550 bytes, run9 167 ->397710 ->643470 ->962950 ->1569158 ->1573254. Runs1/5/6/10 had consumed the full2098054-byte body before or at failure. This contradicts a permanently stopped multipart drain in those fresh samples. The observer logs affect timing and these are not post-fix gates.

Most public Netty executor pendingTasks counts were zero, some transient1/2. Failure stacks often show event loops in EPoll.select, without a sustained upload/configuration lock owner. Incoming-channel read/write/capacity snapshots are non-atomic and must not be used to assert an invariant from sampled mismatches.

The pipeline has two RequestBodyHandler and two NettyApplicationCallHandler instances. Exact Ktor source manually fires channelActive during initialization and adds these handlers in NettyHttp1Handler.channelActive. The first application handler consumes ApplicationCall without forwarding it, so duplicate handlers are an anomaly, not proof of double dispatch or the stall. Single-call-thread diagnostic passed isolated, contradicting a simple one-dispatcher deadlock claim. asStream overrides bulk reads, refuting byte-at-a-time copying. Publication fsync/native writes were observed transiently, not as sustained owners. Ktor respondText uses OutgoingContent and does not repeat generic type metadata; do not pursue that unsupported hypothesis.

Reproduce and continue

From a fresh clone of the diagnostic branch, rebase on origin/main first. Run JAVA_TOOL_OPTIONS=-XX:ActiveProcessorCount=2 scripts/test.bash --local --test testVersionedUploadReadersSeeCompletePaths --log /tmp/reader.log for the current diagnostic test. For the exact genuine-concurrency amplifiers, follow investigation/cn649/README.md and its saved launch collector, compile Cn649Run.java against the captured public test classpath, then use cn649-progress-ten.py. Cn649Probes.java adds public coroutine dumps at failure. No reflection or mocks are used. Current production behavior is original; normal progress logging is diagnostic only.

Full failure/coroutine stacks, raw counters and reusable drivers are durable in the directory above. JFR binaries, build/dependency jars and absolute resolved classpaths were deliberately excluded; recreate classpath with the saved collector after building. No service is required by the test beyond its own real local HTTP/config/container instances.

Still required: establish a named complete mechanism with a reliable failing public-API reproducer; implement and prove the root fix; 20 consecutive post-fix reproducer passes; PR changed tests3x; one full suite with API counts; rebase/update actual OPEN PR branch, why-first review-round description, final-head test/code review and plain build-watchman0.0.18 --pr (never --to-merged). None of those post-fix gates was met or skipped by calling isolated diagnostic passes equivalent. No CI watch was started because there is no verified final PR head. Lane ends BLOCKED near its90-minute time box; supervisor can assign continuation from this checkpoint.

STATUS: BLOCKED Complete upload-stall mechanism and verified fix not established; diagnostic evidence saved, actual PR untouched and all post-fix gates unmet.

Unverified experiments: compatible common-record decoder, persisted-row public test, fixture-owned platform HTTP decoding workers. Combined candidate failed 9/10 amplifying runs. Do NOT merge or call this a fix. History includes a reverted client-executor-only experiment.

All three refs were pushed and their exact heads verified with git ls-remote. Original evidence refs listed in the historical snapshot below were also re-verified and preserved. The rejected stateful branch and older stateless SingleScan leftover have no open PR; current stateless tests supersede them. Nothing needed closing.

Upload findings and evidence

The mechanism is an absent missing/blank-image guard in jarUploadAdminResponse, and the evidence is the existing HTTP test returning 201 instead of the required full 400 error on original head 1eff6fe7: https://buildtest.kotlin.build/run?id=a7f5f7a2 (one failure, 661 filtered, every result page read). The saved guard was installed only after this fail-first run. Exact candidate 2cc00b99 passes all four affected HTTP/HTTPS/URL tests: https://buildtest.kotlin.build/run?id=60e082d7 (4 passed, 658 filtered, every page read). URL fixtures now use the actual JAR provider and assert original bytes, complete replacement bytes, canonical persisted/runtime images, legacy port/transport aliases and resource closure; old startup sleeps were removed.

Full remote https://buildtest.kotlin.build/run?id=c9b53217 reports 662 canonical passes, but automatically repeated two tests after failed first attempts. API pagination covers all seven materialized pages: 654 unique PASSED rows, totalCount=654, complete=false, reconciliationPending=true; eight results are not yet reconciled. Do not report this as a clean 662-test API verdict.

Added test blocker: testVersionedUploadReadersSeeCompletePaths first failed with java.net.SocketTimeoutException: Read timed out at request readBytes(), then upload(), then test line 182, before later automatic passes. Local reproduction at the exact candidate is 4/5 failures with five independent genuine end-to-end invocations at once, each with -XX:ActiveProcessorCount=2 and existing test JVM limits. Each still does 20 sequential uploads and two genuine readers checking complete files. The test's socket deadline, stress counts and assertions were unchanged. A prior isolated run passed, proving isolated green is insufficient. The underlying request/config-update stall mechanism is not yet identified. Server shutdown logging occurs from test cleanup; it does NOT prove that route removal stopped its own listener.

Reproduce after fetch/rebase using JAVA_TOOL_OPTIONS=-XX:ActiveProcessorCount=2 scripts/test.bash --local --test testVersionedUploadReadersSeeCompletePaths --log <log>; run five independent invocations simultaneously to exercise the observed path. Then capture request/config-update thread state BEFORE its existing 10-second socket-read deadline. Replace host-sensitive amplification with deterministic public-API ordering once the exact mechanism is understood. No guessed timeout/retry change is permitted.

Untouched intermittent failure recorded for its owner, not chased: testUrlFacadeActiveQueryReturnsEveryMatchingProvider in https://buildtest.kotlin.build/run?id=c9b53217, first line "The active query has room for both providers and must not stop after its first non-empty candidate response ... Expected <2>, actual <1>." Later automatic attempts passed; this lane did not rerequest it.

Full candidate Gradle run: 925 tests, 924 passed, one failed, zero errors/skips. Untouched SingletonLockProcessE2ETest.secondRealContainerNurseryExitsOneAndLeavesIncumbentServingWithStateUntouched failed "ContainerNursery did not serve /health/live: Connection refused." The child emitted an unhandled OomScoreAdjustmentFailedWarning at OomProtection.kt:146 caused by java.io.IOException: Permission denied writing oom_score_adj. Complete stack is in the uploaded lane findings. This was not chased or rerun.

Log findings and evidence

Original a33aa8e3 full direct run https://buildtest.kotlin.build/run?id=618306b5 and required CI https://buildtest.kotlin.build/run?id=ff48f956 both report 650 passed / 2 failed. Failures: added testAdminLogsConcurrentClients reaches its unchanged 30000ms deadline while waiting on a client Future; old testHttpsAdminApi_queryParametersAreHonored expects returned_lines for invalid lines=2?1 although the new parser correctly returns a descriptive 400. The latter is a deterministic old expectation of the changed public contract, not an unrelated intermittent failure.

The query migration at 55a8405d asserts full status and the complete error "Invalid lines '2?1': page size must be a positive integer" and preserves valid-query checks. Its local target and remote https://buildtest.kotlin.build/run?id=9f5b6302 pass (1 passed, 651 filtered, every page read). No production change was needed for that mismatch.

The original concurrency test fails 10/10 local baseline invocations with -XX:ActiveProcessorCount=2 and the existing 128MB/JIT-tier-1 JVM limits: nine capture snapshot deadlines (1000ms) and one overall deadline (30000ms). All 64 clients, 25,000 rows, EOF barriers, scan/reader exact counts and content assertions remain. Existing HTTP code already dispatches work to Dispatchers.IO, refuting the idea that missing offload alone is the cause. Moving client decoding to separate platform threads alone also fails; that experiment was reverted.

JFR measured 294 GC pauses totaling 4.247 seconds in 15 seconds, peak heap 127.83MiB, and several GiB of weighted allocation dominated by JSONTokener strings, JSONObject maps/numeric parsing, and full log-row scans/serialization. Thread dumps also show clients decoding response JSON while capture snapshots wait. These are OBSERVED contributors, not a complete verified mechanism. JDK 21 blocking-reader code uses ReentrantLocks; virtual-thread pinning was NOT established and must not be claimed.

The fast canonical three-field decoder falls back to org.json for escaped strings, legacy extra fields, whitespace and other formats. A new public RollingFileLogCapture persisted-row test covers every field order, escaping/control Unicode, quoted timestamp plus extra object, empty levels/Unicode messages, and invalid/duplicate/missing/null rows; it passes. Fast decoding alone still fails concurrency. Combining fast decoding and separate client workers at 765c497b passed one isolated two-test run (concurrency 22246ms), but failed 9/10 follow-up genuine concurrent invocations (three independent instances at a time), all at the same 30000ms deadline. Therefore the candidate is not a verified fix. Root cause remains open.

Reproduce with JAVA_TOOL_OPTIONS=-XX:ActiveProcessorCount=2 scripts/test.bash --local --test testAdminLogsConcurrentClients --log <log> on original a33aa8e3, then use the same exact scenario on the candidate. No artificial CPU load, timeout increases, reduced counts or weakened assertions. The candidate full remote attempt is https://buildtest.kotlin.build/run?id=df3ada07 (ContainerNurseryLogs, 653 tests, submitted 2026-10-04 06:17:17 UTC), uploading at the latest snapshot. Its client is still active; no full-suite verdict is claimed. Watchman reports result-view HTTP 503 during materialization, which does not establish executor failure. It must be judged from fully paginated result API and failure attempts, not client exit status.

Historical provisioning failure https://buildtest.kotlin.build/run?id=57f6afe7 was an infrastructure verdict: addSshKeyToDroplet timed out after 30s after sandbox connection invalidation; zero completed tests. Exactly one check-suite rerequest was made in this lane. The subsequent required CI failed actual tests as recorded above; no further rerequest was made.

Reviews, limits, and next actions

Separate test-comprehensiveness and source review passes examined the original public contract before these blockers surfaced. New candidate source remains unverified; final supervisor review is still required. Upload publication deliberately uses atomic no-replacement hard-link publication of fsynced bytes because JDK ATOMIC_MOVE can replace targets; non-hardlink filesystems reject. This differs from literal rename wording and is recorded, not silently ignored. Stateless log retention can omit survivors within an altered equal-timestamp cursor boundary to avoid duplicates; other groups continue. Exact total_lines needs count-only archive scans; provider totals count provider-delivered records.

Remaining necessary work is specific: identify and deterministically reproduce the upload added-test stall; identify and fix the log added-test mechanism; prove both original failing scenarios now pass reliably without changed budgets; review the final tests/source independently; run exact-head shared-contract full gates; only then update the still-open PR branches and watch required checks. Passing query migration can be extracted from its clean branch without taking failed performance experiments. The supervisor alone may decide merging or completing this handoff. No BuildTest*/kompile* changes, deployment, restart or publication steps were worked; challenge-report automation was not called because it automatically enqueues/merges and this lane prohibits those actions.

A full incremental lane findings report is uploaded with this handoff, including commands, failure stacks, measured evidence and plan disposition. It is the durable report; local /tmp logs and checkouts are supplementary and may disappear.

Historical 2026-10-02 snapshot (preserved evidence, not live truth)

Finish ContainerNursery PRs 649 (versioned JAR upload) and 650 (stateless log paging): final heads, green checks, reviews, enqueue

RE-VERIFY before acting. Everything below is a write-time snapshot taken 2026-10-02 ~21:50 UTC when the session was stopped on request. Re-check with gh pr view 649 --repo CodexCoder21Organization/ContainerNursery --json state,mergeStateStatus,statusCheckRollup,headRefOid (and 650), and git ls-remote every branch in the table. No merge, enqueue, or production deploy has happened; none is authorized without a clean final review. Nothing from this effort is deployed to the production ContainerNursery.

Mission

The user asked: "Fix ContainerNursery's live-update and log behavior. Make jar uploads switch versions atomically so an upload cannot overwrite the running route in place. Make log time and level filters work on the server, then apply line limits and pagination to the filtered results. The latest log report says the command returned lines outside the requested time window and ignored the level filter." Challenge reports: https://github.com/CodexCoder21Organization/PlanRepository/blob/main/challenges/2026-09-26-2247-containernursery-cli-upload-jar-route-overwrites-the-live.md and https://github.com/CodexCoder21Organization/PlanRepository/blob/main/challenges/2026-10-02-1143-containernursery-cli-container-logs-caps-at-10-000-lines.md.

This handoff covers the server side (repository https://github.com/CodexCoder21Organization/ContainerNursery). The client side (ContainerNurseryApi PR 48, ContainerNurseryCli PR 44) is the handoff hf-2026-10-02-finish-api-publication-and-verify-containernursery-cli-paging-and-upload-behavior. All three repositories implement one binding wire contract, preserved at https://github.com/CodexCoder21Organization/PlanRepository/blob/wip/cn-liveupdate-evidence-2026-10-02/handoffs/artifacts/2026-10-02-cn-liveupdate/contract.md — read it first.

What was found and done (the chain)

Diagnosis (verified with fail-first tests on main):

Logs: the HTTPS admin dispatcher (src/main/kotlin/org/example/facade/HttpsFacadeProvider.kt, the path production uses at https://api.nursery.wasmserver.com) parsed only lines and since for /logs/container/{key} and /provider, dropping until and level; the HTTP admin provider forwarded all four. The capture (RollingFileLogCapture) applied a newest-10 000 cap (MAX_READ_COUNT) before any window. A second real bug was found: after the capture reopens, generation zero listed its archives twice (in both inheritedHistory and archives), so records were counted and served twice.
Upload: after https://github.com/CodexCoder21Organization/ContainerNursery/pull/621, a route upload still ignored filename and renamed the new bytes over the route's current image path, so the live path's content changed under the running route and a two-step deploy was impossible.

PR 650 — log filtering then paging (branch wip/log-filter-then-page, head a33aa8e3): both admin paths call one shared parse+page function; filters (since, until, level comma list) apply over the whole retained history before the page; the cursor is a stateless base64 token carrying mode, filter and (timestamp, ordinal) position, validated against the request filter (400 with both filters named on mismatch); window mode pages oldest-first from since, tail mode pages newest-first backward; each request reads only archives overlapping its window in one sequential pass with one reader per file and closes its own readers; matched_lines, truncated, next_cursor added; provider logs filtered server-side when the provider cannot. A first design that kept per-cursor server-side snapshot copies (with a 32-snapshot cap, expiry, byte budget) was rejected and removed; a cross-request row-count cache that could publish a stale count after a writer replaced the file was also removed after a fail-first test. 12+ scenarios under tests/testAdminLogs*.kts including 64 concurrent clients × 25 000 rows, byte/read-count proofs of single-pass reads, admin-path parity, validation, and provider/request endpoints. The continuation lane reported all of its assigned items DONE with the candidate passing 7/7 locally; its remote full suite had not returned a run id when stopped. CI on a33aa8e3 (pushed at stop time) was just starting.

PR 649 — versioned JAR upload (branch wip/upload-versioned-switch, head 1eff6fe7): every upload lands at a new path (filename honored; collisions get a derived versioned name), staged + fsync + atomic rename; with a route, the route's image is switched to the new path (preserving ?args=) through the same atomic config write route updates use, then the container restarts; the previous jar stays on disk; rollback (/jars/versions, /jars/rollback) walks route image history ordered by successful-switch order (a wall-clock-backward Clock test proved timestamp sorting was wrong); legacy <name>.prev-<version> files from PR 621 still listed/rollback-able; invalid filenames → 400 naming value and rule; failed switch removes the uploaded file. 28 new scenarios (tests/testVersioned*.kts, tests/testHttp*VersionedRouteUpload.kts, etc.), all 15 pre-existing retention scenarios migrated to the new contract, and the Gradle/JUnit upload tests (src/test/kotlin, 29 scenarios) rewritten to the new contract by a separate lane (full Gradle 923 passed / 2 failed; the 2 were a real regression — a route upload with no configured image returned 201 instead of 400 — which head 1eff6fe7 "Cover rejected uploads for routes without an image" addresses). The implementing lane's full remote suite on an earlier head: 660 passed / 2 failed, the 2 being "URL fixture" scenarios still being migrated when stopped; its in-progress working tree is pushed (branch below).

Deployed/published: nothing. No ContainerNursery artifact was published and the production instance was not touched (verified: no publish or deploy command in any lane's findings; kotlin.directory has no new containernursery version from this effort).

Next steps

PR 649: continue from wip/upload-versioned-switch-handoff-2026-10-02 (or from 1eff6fe7): finish migrating the two remaining URL-fixture scenarios (named in r1-findings.md under "two URL fixture migrations"), run the touched scenarios locally, one scripts/test.bash --remote full suite, push to the PR branch, update the PR body (REST PATCH), get Gradle + kotlin.build (remote) green. Then test-comprehensiveness and adversarial reviews against the final head (reuse the review-brief pattern in the evidence branch briefs/review-common.md), final review, enqueue.
PR 650: check CI on a33aa8e3; obtain one remote full suite (or local fallback of every touched file after 10 minutes without progress); update the PR body to describe the stateless cursor design (it must say the snapshot-expiry test was removed deliberately with the rejected design); reviews; final review; enqueue. Both PRs touch HttpsFacadeProvider.kt and AdminContainerProvider.kt in different regions; whichever lands second takes a mechanical rebase.
After both land: the client handoff's CLI work can then be verified end-to-end against a server build, and a ContainerNursery version bump/publish + production deploy is a separate, user-authorized step.
File the three challenge reports listed in the client handoff (gh pr edit GraphQL failure, build-service congestion/provisioning-deadline, kompile coordinate substitution) if not already filed.

Reusable / operational knowledge

Two admin code paths exist (HTTP admin provider and HTTPS facade dispatcher) and had diverged; production uses the HTTPS one. Any admin endpoint change must be made in a shared function and covered by a parity test.
The repository has two test trees: kompile tests/*.kts (run by kotlin.build (remote)) and Gradle JUnit src/test/kotlin (run by the Gradle check). A behavior change must update both; the Gradle tree was the one the implementing lane missed.
Local kompile runs across lanes must be serialized under one flock; the lock queue was the throughput limit with 4-5 lanes.
gh pr edit fails on this host (classic-projects GraphQL field); use gh api -X PATCH repos/OWNER/REPO/pulls/N --input body.json.
The stateless cursor design was chosen over server-side snapshots deliberately: a read-only admin endpoint must not own per-request resources with caps and expiry; retention shortening the tail while paging is acceptable and honest.
