L3s acceptance findings

Request: run the candidate acceptance gates alone for https://github.com/CodexCoder21Organization/kotlin-build-ci/pull/296 and push only under the registered verdict rule.

Plan:

• [done] Read prior evidence and required docs; fresh checkout, identity, rebase and isolation audit.
• [done] Focused 151 explicit-path gate once, local: requested151/151 PASS, raw152/152 PASS, 926.386 seconds.
• [done] Full local suite once:1181 PASS/3 FAIL,2677.533 seconds; exit1.
• [done] Registered verdict does not qualify; evidence checkpointed. Conditional shared push/PATCH ineligible.
• [done] Watch ineligible (no push); final RUNNING report acknowledged and process audit complete.

Standing constraints: no merge, enqueue, deploy, Maven publication or excluded-repository edits; unchanged per-test caps, data and assertions; never kill foreign processes. Start 2026-10-09 03:29 UTC; use the earlier 120-minute hard stop (05:29 UTC) because the brief also names 150 minutes. Parent handoff stays RUNNING and claimed by fable-drain-20261004.

2026-10-09T03:29:50.674941+00:00 — OBSERVED: Read L3r final audit and failure evidence. Candidate 1aa63e62 has five passing new tests; previous focused gate recorded 150/151 and full was bounded without counts during foreign L1p overlap. INFER: prior gate evidence does not qualify this candidate; new isolated runs are required. No code changed. Skills selected: github-repos, status-report, watch-build. Status scheduler tools are unavailable; report cadence will be maintained in the active tracked-command monitoring, without ending the task.

2026-10-09T03:31:45.983780+00:00 — OBSERVED: Fresh candidate rebased without conflict on main e6bdf688bc2e10cbd206ce886369efb822cafd70, head unchanged 1aa63e62d2b7752046b9976f7e16d4e5030bf64e. Required README, PHILOSOPHY.md and TESTING.md (including Never Calibrate a Reproducer to a Machine) read; repository AGENTS.md absent. rg unavailable, using grep. Foreign ContainerNursery test JVM present at first scan; beginning the registered bounded isolation wait. Full process output saved to preparation-processes.txt. INFER: exclusive execution has not yet been established; load numbers alone cannot establish it.

2026-10-09T03:33:22.615549+00:00 — OBSERVED: First milestone pushed to https://github.com/CodexCoder21Organization/kotlin-build-ci/tree/wip/l3s-evidence-20261009 at https://github.com/CodexCoder21Organization/kotlin-build-ci/commit/de131bc8 . Manifest resolved to 151 unique existing test paths. One-attempt public LocalBuildWorkspace wrapper preserves four workers and forces maxTestAttempts=1; no timeout override. Foreign runners remain in the isolation wait. INFER: strict runner prevents built-in retries from obscuring first-attempt results.

2026-10-09T03:33:56.501675+00:00 — OBSERVED: Isolation wait ended before its bound; immediate pre-focused scan contains no Java/test process. Pre-gate 03:33:56 up 35 days, 1:25, 0 user, load average: 17.42, 21.00, 25.61. Rebase before build remains main e6bdf688 / head 1aa63e62. Plan preparation DONE, focused gate IN PROGRESS; full gate and shared push pending. Exact manifest has 151 paths, max attempts 1, four workers, 1500-second outer bound.

2026-10-09T03:35:13.245749+00:00 — RUNNING status report. Original request: run the kotlin-build-ci candidate acceptance gates alone and push on the registered green decision, then observe required CI and report without merging. OBSERVED: https://github.com/CodexCoder21Organization/kotlin-build-ci/pull/296 is OPEN/DIRTY at c71d60566003ae73dccd558a092eac3546080b1e (latest live check at 03:33 UTC). Fresh candidate 1aa63e62 is unchanged after rebase onto main e6bdf688. Foreign L1p and L3r runners ended before focused execution; strict focused151 is actively preparing, and its launcher prints maxTestAttempts=1 despite the CLI requesting 3. First evidence checkpoints de131bc8 and 3f836d6a are remote. No new code change or acceptance count yet.

The candidate saves rerun admission before outbound creation and keeps saved completion ownership during callbacks. It protects retained receipts and tracker snapshots across concurrency and restart. Its tracker cache shares byte storage and uses bounded writes, while the shadow Java probe compiles before timed test execution.

Source analysis verification correction: /tmp/l3q-coverage-review.md says prepublication release and separate-process peer-cache tests passed on the old baseline; replacement receipt coverage also passed via an existing guard. Thus the literal request to describe all six rows as fail-first fixes is refuted by the prior evidence. The PR description will state six rows with public-API tests and distinguish demonstrated fail-first defects from baseline-passing coverage; no failure will be invented.

Delegated work at a glance: no delegated work active or recently finished in L3s. Landing parallelization sweep: gates must run sequentially and alone under this brief; no permitted uncovered parallel gate. Blockers: none at this point. Remaining steps: focused verdict, full local verdict, registered decision, conditional shared push/PATCH and required-check watch, final RUNNING parent handoff report and cleanup. Lessons: capture process identities before claiming isolation; preserve first-attempt results by disabling runner retries; separate baseline-passing coverage from fail-first defect evidence. Parent handoff claim, completion and release are untouched.

2026-10-09T03:38:00.967920+00:00 — OBSERVED: Initial RUNNING handoff report acknowledged, exit 0 after 60.290 seconds; no retry. Full source-analysis coverage review read at /tmp/l3q-coverage-review.md; it records baseline-passing coverage items alongside actual fail-first defects. Gate still preparing, CLI wrapper confirmed maxTestAttempts=1 requestedAttempts=3. No code changed.

2026-10-09T03:38:57.061118+00:00 — OBSERVED: focused tracked process still running at 300 seconds; log 25547 bytes. Process identities captured in focused-processes.txt. Counts not yet published. INFER: no verdict until tracked exit and complete test results.

2026-10-09T03:43:57.476464+00:00 — OBSERVED: focused tracked process still running at 601 seconds; log 29979 bytes. Process identities captured in focused-processes.txt. Counts not yet published. INFER: no verdict until tracked exit and complete test results.

2026-10-09T03:48:51.372707+00:00 — OBSERVED: Focused gate entered runtime by the 781-second snapshot; preparation thread dump at 688 seconds shows prepareTests waiting for an actively compiling Kotlin worker. Current test JVMs all have L3s cwd. Raw log includes TerminalMemoryWarningEffect: expected the record to be the final stdout line, but received later output. Full warning stacks retained in focused.log; no test-count verdict yet. INFER: warning alone is not assigned a test failure or cause here. Toolchain repository edits and automatic report-challenge merges are prohibited; report this warning to the orchestrator through findings without changing those repositories.

2026-10-09T03:48:57.700939+00:00 — OBSERVED: focused tracked process still running at 901 seconds; log 262012 bytes. Process identities captured in focused-processes.txt. Counts not yet published. INFER: no verdict until tracked exit and complete test results.

2026-10-09T03:50:21.297512+00:00 — OBSERVED: Focused gate exit 0 after 926.386 seconds, 152 PASS / 0 FAIL. All 151 requested manifest functions appear exactly once and pass. Explicit file-path selection also discovers exerciseParkedDirectRepairReverificationMatrix in testBuildWatchmanParkedDirectRepairReverifiesSuite.kts; that additional function passes. This explains the difference from L3r function-selector total, with no missing/duplicate manifest result. Known parked reconciliation test PASS 4930ms; five new tests PASS: point write 5901ms, record writer 7495ms, retained snapshot 9866ms, short record 10198ms, shadow backlog 14917ms. 03:50:21 up 35 days, 1:42, 0 user, load average: 17.02, 21.36, 24.48. Plan focused DONE; full next. INFER: requested focused151/151 condition met; raw total152/152 transparently recorded.

2026-10-09T03:50:25.742573+00:00 — OBSERVED: Immediate pre-full audit has no foreign Java/test work. 03:50:25 up 35 days, 1:42, 0 user, load average: 17.10, 21.30, 24.45. Rebase before build remains main e6bdf688 / candidate1aa63e62. Full local suite IN PROGRESS once: scripts/test.bash --local --test ., maxTestAttempts=1, four workers, unchanged per-test caps, 3600-second outer bound.

2026-10-09T03:51:02.389805+00:00 — RUNNING status report, 20-minute cycle. Original request: run the candidate gates alone, push only under the registered verdict, observe required CI once and report without merging. OBSERVED: https://github.com/CodexCoder21Organization/kotlin-build-ci/pull/296 freshly OPEN/DIRTY at c71d6056, not merged. Candidate remains 1aa63e62 based on main e6bdf688. Focused151/151 requested functions PASS; explicit paths also run one matrix helper, raw152 PASS/0 FAIL, exit0, 926.386s wall. Full local once is now preparing, with maxAttempts1 and four workers. Pre-full audit includes only lightweight parent handoff uploads; no foreign workspace test runner or test JVM. Current logs and process evidence have progressed, not a presumed count. Evidence checkpoint404b2d96 includes the complete focused verdict.

Rerun admissions are saved before outbound work and saved completion ownership remains authoritative during callbacks. Receipt reads and terminal retention stay correct through concurrency and restart. Tracker cached byte ownership and bounded writes retain memory limits, while the shadow probe compiles in preparation.

Delegated work at a glance: none active or recently finished in L3s. Landing parallelization sweep: this lane must run acceptance gates sequentially and alone; no permitted uncovered parallel gate. Blockers: none. Next steps: finish the full local verdict, apply the registered decision, conditionally push/PATCH, observe required checks once, upload the final RUNNING handoff report and stop. Lessons: identify owning processes instead of inferring isolation from load; report file-selector extra functions explicitly; retain baseline-passing coverage as refutation rather than inventing fail-first results. Parent claim/completion/release untouched.

2026-10-09T03:52:47.955697+00:00 — OBSERVED: 20-minute RUNNING upload exits1 after30.502s; no acknowledgement. Exact error and full stack follow. One permitted retry starts; initial report remains acknowledged. INFER: no presumed service-side outcome or rollback.

Sandboxed code threw an exception: java.lang.InternalError: Exception encountered in implementation of foundation/url/sjvm/intrinsics/ServiceBridge:rpc(Ljava/lang/String;Ljava/util/Map;)Ljava/util/Map; :
foundation.url.resolver.PersistentRpcConnection$AmbiguousRpcRequestException: RPC request 'submitStatusReport' to service 'handoff' has an ambiguous outcome because its transport failed after the request write began. The request was not replayed because the remote handler may already have run. Original transport failure: Persistent RPC connection to service 'handoff' was closed while requests were still pending. Reader transport failure: java.io.EOFException: Stream closed while reading message data (read 0 of 4 bytes). cause: foundation.url.resolver.UrlResolutionException: Persistent RPC connection to service 'handoff' was closed while requests were still pending. Reader transport failure: java.io.EOFException: Stream closed while reading message data (read 0 of 4 bytes).

2026-10-09T03:54:51.851631+00:00 — OBSERVED: One permitted 20-minute report retry acknowledged, exit0 after35.798s. First report20 outcome remains ambiguous; its CLI printed no fuller stack than the captured transport-error text. Full suite remains in preparation with only L3s Java/test work. No service cause inferred or excluded repository changed.

2026-10-09T03:55:26.264762+00:00 — OBSERVED: full tracked process still running at 300 seconds; log 464239 bytes. Process identities captured in full-processes.txt. Counts not yet published. INFER: no verdict until tracked exit and complete test results.

2026-10-09T04:00:26.514508+00:00 — OBSERVED: full tracked process still running at 601 seconds; log 468507 bytes. Process identities captured in full-processes.txt. Counts not yet published. INFER: no verdict until tracked exit and complete test results.

2026-10-09T04:05:26.763983+00:00 — OBSERVED: full tracked process still running at 901 seconds; log 468507 bytes. Process identities captured in full-processes.txt. Counts not yet published. INFER: no verdict until tracked exit and complete test results.

2026-10-09T04:06:47.648248+00:00 — OBSERVED: Full suite entered runtime by the 961-second snapshot; live test JVMs ['2245611', '2245784', '2245842'], foreign workspace Java processes []. Preparation worker snapshot at725s showed four active Kotlin compiler workers. Test counts still unpublished. No code changed.

2026-10-09T04:10:03.053364+00:00 — RUNNING status report, 40-minute cycle. Original request: run candidate acceptance gates alone and push under the registered verdict, then observe required CI once and stop without merging. OBSERVED: https://github.com/CodexCoder21Organization/kotlin-build-ci/pull/296 freshly OPEN/DIRTY at oldc71d6056, not merged. Candidate remains1aa63e62 based on e6bdf688. Requested focused151/151 PASS (raw152/152 including the additional path-selected matrix helper), 926.386s wall, one attempt. Full suite moved from preparation to runtime by961s and continues with rotating L3s test JVMs and growing log; counts remain unpublished. Thread snapshot at725s showed active compiler workers. Runtime checkpointd48f5bb4 is pushed. No other workspace test JVM observed during either gate. The last 20-minute RUNNING upload was acknowledged on its one retry; its first request remains ambiguous.

Rerun admission is committed before outbound work; saved completion ownership survives cancellation callbacks. Receipt ownership and expiry protect live work through concurrency and restart. Tracker cached encodings share the immutable snapshot and writes stay bounded, while the shadow Java probe compiles before timed execution.

Delegated work at a glance: none active or recently finished in L3s. Landing parallelization sweep: acceptance gates must run sequentially and alone; there is no permitted uncovered parallel gate. Blockers: none at this point. Next steps: obtain the full verdict, apply the registered rule, conditionally update the shared branch and description, observe required checks once, upload the final RUNNING handoff report and stop. Lessons: preserve process identity evidence throughout a gate; count every path-discovered execution while checking all requested selectors; distinguish a quiet preparation log from a compiler stall with actual thread evidence. Parent handoff claim/completion/release remain unchanged.

2026-10-09T04:10:27.089113+00:00 — OBSERVED: full tracked process still running at 1201 seconds; log 1104311 bytes. Process identities captured in full-processes.txt. Counts not yet published. INFER: no verdict until tracked exit and complete test results.

2026-10-09T04:13:05.028900+00:00 — OBSERVED: 40-minute RUNNING handoff report acknowledged, exit0 after60.932s; no retry. Full suite remains in runtime with rotating L3s bootstrap test JVMs; result file not yet created at21-minute check. All acceptance data and assertions unchanged. No aggregate count inferred from current JVMs.

2026-10-09T04:30:43.698013+00:00 — RUNNING status report, 60-minute cycle. Original request: run candidate gates alone, conditionally push and observe required CI once, then report without merging. OBSERVED: https://github.com/CodexCoder21Organization/kotlin-build-ci/pull/296 freshly OPEN/DIRTY at c71d6056, not merged. Focused151 requested functions all passed, raw152/152, 926.386s wall. Full once remains active at roughly40minutes, with rotating L3s test JVMs; testBuildRunner_mixedGateTrafficAdmitsEachClassInArrivalOrder is currently running under its existing300000ms annotation. Existing annotated limits remain unchanged, and new shadow test/default cap remain30000ms; no timeout override was applied. No aggregate count yet. All observed gate test processes belong to L3s. Source1aa63e62 unchanged on e6bdf688; evidence checkpoint45aefe20 is remote. Previous40-minute RUNNING report acknowledged. This isolated full attempt has already exceeded the rough25–35-minute estimate; no cause is inferred from elapsed time alone.

Admission is durably committed before outbound creation, and saved completion ownership handles cancellation callbacks. Receipt reads and retention keep live work safe through concurrent delivery and restart. Tracker encodings share immutable bytes with bounded writes; the shadow probe compiles before timed test execution.

Delegated work at a glance: none active or recently finished in L3s. Landing parallelization sweep: gates must run sequentially and alone; no permitted uncovered parallel gate. Blockers: none at this point; no failing verdict published. Next steps: obtain full counts, apply the registered decision, conditionally push/PATCH and watch required CI once, then upload the final RUNNING report and stop. Lessons: preserve raw gate totals alongside manifest totals; keep existing test annotations distinct from driver bounds; verify process ownership throughout the run. Parent handoff claim/completion/release are untouched.

2026-10-09T04:33:24.151248+00:00 — OBSERVED: 60-minute RUNNING handoff upload acknowledged, exit0 after45.328s; no retry. Full gate remains active with counts pending; this attempt remains unchanged and within3600s.

2026-10-09T04:35:16.152704+00:00 — OBSERVED: Full gate terminal exit1 after2677.533s, 1181 PASS / 3 FAIL. Failed records [('testBuildRunner_restartTwiceAcrossPrimaryUploadBoundaries', '33035'), ('testStress_watchdogCronDeletionVisibleAfterCleanup', '9800'), ('testBuildRunner_mixedGateTrafficAdmitsEachClassInArrivalOrder', '302541')]. 04:35:16 up 35 days, 2:27, 0 user, load average: 23.64, 26.75, 25.70. Registered push rule does not qualify if any failure differs from the known parked reconciliation test. Full first-attempt results and stacks preserved. Plan full attempt DONE; cause assessment IN PROGRESS; shared push and required-check watch not eligible yet. No unchanged acceptance rerun.

2026-10-09T04:39:58.832049+00:00 — FINAL STATE OF PLAY (gate decision, no source fix). OBSERVED: Candidate1aa63e62 on maine6bdf688 completed both registered local gates with maxTestAttempts1 and four workers. Requested focused151/151 PASS; raw152/152 including the additional path-discovered matrix helper, exit0,926.386s. Full1181 PASS/3 FAIL, exit1,2677.533s. The allowed parked reconciliation exception passed. No foreign test JVM was observed during gate execution. At the post-gate04:40 snapshot L3t Java work is now present; it was not present in the captured gate-time observations and is not owned or killed by L3s. Live PR https://github.com/CodexCoder21Organization/kotlin-build-ci/pull/296 remains OPEN/DIRTY at c71d60566003ae73dccd558a092eac3546080b1e, mergedAt null. INFER: focused condition is satisfied, but full condition is refuted by three non-exempt failures. The shared branch push, description PATCH and post-push required-check watch therefore are not authorized by the registered green condition. No source code, test, payload, iteration count or timeout changed. No acceptance rerun, deployment, publication, merge or enqueue occurred.

Failure assessment (OBSERVED, not proposed root causes):

• testBuildRunner_restartTwiceAcrossPrimaryUploadBoundaries:33035ms, test runner reports30000ms cap. Its sampled main thread is RUNNABLE at withCheckRunCancellationLock(BuildRunner.kt:12054); a second dump shows main awaiting boundary latch at test line226. Console completed the first boundary, started the zero-chunk boundary, and resumed upload through finalization. The observed location does not establish lock deadlock; no causal diagnosis or reliable fail-first fix is claimed. Full record: restart failure.
• testStress_watchdogCronDeletionVisibleAfterCleanup:9800ms, webcronapi.WebCronApiException: Internal server error: null from HttpWebCronService.executeRequest305/listJobs56 at test232, the immediate listJobs read while the real WebCron projection subscription and webhook deletion are active. Iteration8 logs show both builds cleaned up and the watchdog deletion finishing during teardown. The captured record contains the client exception and its full stack but no underlying server-side exception. HTTP500 contradicts the listJobs contract; the record does not establish whether the server projection, event-log interaction or another dependency caused it. No consumer workaround added. Full record: WebCron failure.
• testBuildRunner_mixedGateTrafficAdmitsEachClassInArrivalOrder:302541ms, existing300000ms annotation. Main awaited completed at test226. Runtime and terminal dumps show many gate waiters, one tracker snapshot comparison in the publication path, and continued rounds (pool36 at the terminal dump). These snapshots establish ongoing work and where callers wait, not a verified deadlock or specific expensive operation causing the aggregate deadline. No ordering assertion failure was recorded before termination. Full record: mixed traffic failure.

INFER: None of these three failures can be excused under the one named exception. A passing focused gate cannot support a100% full-suite verdict. The premise that isolation would make this candidate qualify is refuted for this attempt; whether these failures predate the candidate remains unproved. At04:41 about48minutes remain under the earlier120-minute bound. The observed full gate alone took44.6minutes, leaving about3minutes for diagnosis, deterministic reproductions, cause fixes and affected-neighbor verification before starting another full gate. I cannot honestly provide three cause fixes, deterministic failing reproducers, affected-neighbor passing results and another full gate within that bound. Per step4's explicit “if you cannot, stop and report,” the lane stops on this failed decision with evidence preserved. No speculative fix, parameter change or unchanged rerun is substituted for proof.

Resume using the remote candidate and evidence, not this local checkout. Candidate: https://github.com/CodexCoder21Organization/kotlin-build-ci/tree/wip/l3r-invariants-20261009 (remote1aa63e62). All new lane evidence: https://github.com/CodexCoder21Organization/kotlin-build-ci/tree/wip/l3s-evidence-20261009/diagnostics/L3s (checkpoint8e4703ad already remote; final snapshot follows). Shared PR stays on c71d6056. No deployed or published code from L3s exists. Both local worktrees have no stashes or source changes.

Reproduction driver and exact commands are in run-gate.py, L3sStrictCli.java, bin/java, focused151-paths.txt, focused-time.json (full argument vector) and full-time.json. Launcher source enforces one attempt via the public LocalBuildWorkspace factory; official scripts/test.bash is unchanged. Preserve that one-attempt seam when confirming failures; default CLI requested three attempts. Full suite command is scripts/test.bash --local --test . under the recorded PATH prefix,3600s driver bound. Complete raw logs/results and process identities are remote; no stack discarded. Preparation costs~16minutes in this run and is included in gate wall time. Do not presume a short targeted run or expand deadlines. The next permitted work is causal investigation of the three records with deterministic public-API reproducers, then cause fixes, affected tests plus neighbors, then one full gate, retaining all constraints. Upstream BuildTest/kompile/resolver/protocol edits and publication remain orchestrator decisions.

2026-10-09T04:40:23.151658+00:00 — OBSERVED: Source git status is clean; removed the three generated ignored jars/coursier launchers and compiled strict-runner class files. ps -eo pid,args -ww audit saved to cleanup-processes.txt; no L3s-owned test JVM, gate driver, isolation loop or watcher remains. All tracked commands ended; no process needed additional termination. Foreign L3t compiler is untouched. No build artifact is committed. Final handoff upload next.

2026-10-09T04:40:42.986648+00:00 — FINAL lane status report; parent handoff remains RUNNING. Original request: acceptance gates alone and shared push only on the registered green decision. Lane outcome: gates completed and decision does not qualify, three non-exempt full-suite failures remain without a verified cause fix. Requested focused151/151 PASS (raw152/152),926.386s; full1181 PASS/3 FAIL,2677.533s. Final verdict/stack/process evidence checkpoint8c890a20 verified on remote: https://github.com/CodexCoder21Organization/kotlin-build-ci/commit/8c890a20f328f73023ce7de9e0184ee437dadbe6 . Shared PR https://github.com/CodexCoder21Organization/kotlin-build-ci/pull/296 remains OPEN/DIRTY atc71d6056. Candidate source remains1aa63e62; no changed code or new source PR exists. All partial diagnostic work is remote. No delegated work or remaining owned background process. Remaining parent work: diagnose the three full-suite failures with reliable public-API reproducers, verify cause fixes and gates, then decide shared push and CI; L3s does not claim those fixes done. No landing parallelization is allowed during these isolated gates. Lessons: explicit paths can discover extra helper functions; sole-lane process identity does not guarantee green; timeout snapshots are observations, not root causes; the existing whole-suite preparation/runtime together exceeded the rough estimate. Final report upload below does not complete, release or change the orchestrator's handoff claim.

2026-10-09T04:41:28.912392+00:00 — OBSERVED: Final RUNNING upload acknowledged, exit0,17.266s,90s bound. Correction to earlier prose estimate: clock is04:41UTC, about48minutes remain to05:29; the full gate took44.6minutes, leaving about3minutes for all three diagnoses/fail-first fixes/neighbor gates before a repeat full gate. Earlier04:47/~42minutes wording was an estimate error and is corrected above. INFER: unknown mechanisms still prevent a verified causal fix; the registered failed verdict remains unchanged. A corrected final report is uploaded to preserve the accurate record. No retry of the acceptance tests or shared push.
