RE-VERIFY (written 2026-09-30 ~22:25 UTC): this is a snapshot. Before acting, re-check BuildTestEmbedded main, the fail-first branch head, and the state of PRs 1079 and 1080.
2026-09-30 re-verification (board drain, verify-only)
Context: the user asked to "Work through all open handoffs ... decide if they should be merged or closed or if anything from them can be salvaged. Drive them to completion." BuildTestEmbedded was owned by another session on 2026-09-30, so this pass verified state and pushed nothing.
Disposition: KEEP OPEN, needs a design-first implementation effort. Not superseded by main.
Checked firsthand on 2026-09-30:
- main = f2756991458d07f2f14a772558624f18141dc4a6.
- https://github.com/CodexCoder21Organization/BuildTestEmbedded/pull/1015 is still CLOSED, unmerged, head 8073faed. The reference branch fix/terminal-run-test-rows is still at that SHA.
- The fail-first branch https://github.com/CodexCoder21Organization/BuildTestEmbedded/tree/wip/sweep3-w2-r41-terminal-row-failfirst-on-main is still 0c2e3ac5 (base ee070093, 67 commits behind main). It is one tests-only commit, and it cherry-picks cleanly onto main.
- The defect is still present on current main. With the branch's commit cherry-picked onto f2756991 (locally, not pushed),
scripts/test.bash --local on the three selectors gave 0/3:
- testTerminalCanceledRunPublishesCanonicalRowsBeforeSummary: "the feed still contains {} at sequence 3 ... Expected <{passed=PASSED, pending=CANCELED, running=CANCELED}>, actual <{}>" (6.6 s)
- testDeferredTerminalRunPublishesCanonicalRowsBeforeSummary: the same message (8.6 s)
- testTerminalRunPublishesXmlOnlyCanonicalRowsBeforeSummary: "the feed still contains {projectionTest=RUNNING} at sequence 39" (17.4 s). In the feed the row goes RUNNING at 31, TEST_STATUSES_REPLACE comes at 35, and the RUN_UPSERT terminal summary follows at 36-39 without a PASSED row. This matches production run ed55d648.
- Coordination PRs: 1089 and 1092 MERGED 2026-09-24. https://github.com/CodexCoder21Organization/BuildTestEmbedded/pull/1079 is OPEN (last updated 2026-09-30 19:11Z). https://github.com/CodexCoder21Organization/BuildTestEmbedded/pull/1080 is OPEN (last updated 2026-09-30 04:45Z). Both are still live projection work.
- No open BuildTestEmbedded PR targets terminal-row-before-summary ordering. The main commits since ee070093 that touch terminalization (for example PR 1135, which writes recovered verdict log lines before terminal status) do not cover projection test rows. The tests above show this.
Next steps (unchanged in substance):
- Coordinate with the owners of PRs 1079 and 1080 about the ordering of projection-publication changes.
- Rebase the fail-first commit onto main, and write down the mechanism before any code: why the TEST_STATUSES_REPLACE / terminal rows are not visible as canonical PASSED/CANCELED rows before the terminal RUN_UPSERT in the persisted projection.
- Fix at the cause, so that all three tests plus the invariant table below pass. No timeout raises and no weakened assertions.
2026-09-24 rescope
Remaining work (new mission): publish every canonical terminal test row before the terminal run summary, on BuildTestEmbedded main's current persisted-projection design. This is design-first work in an area another live session is actively changing. It does not fit a 90-minute slot.
Why: in production, run https://buildtest.kotlin.build/run?id=ed55d648 showed COMPLETED while its test rows still showed RUNNING or PENDING.
PR 1015 closed (unrebaseable)
https://github.com/CodexCoder21Organization/BuildTestEmbedded/pull/1015 was closed on 2026-09-24 without merging:
- It is CONFLICTING. Its base, bf119c61a, is 81 commits behind main (ee0700938 at the time of closing).
- It was evicted from the merge queue three times on 2026-09-17.
- Since its base, BuildTestEmbeddedService.kt has changed +1901/-743 on main: the persisted projection (https://github.com/CodexCoder21Organization/BuildTestEmbedded/pull/1031), the linear projection (PR 993), and completion reconciliation (PR 1072).
Its journal-level approach is kept for reference on branch https://github.com/CodexCoder21Organization/BuildTestEmbedded/tree/fix/terminal-run-test-rows (head 8073faed315b001dcccb8c1f35f020006636fb91). Use it as a reference for the design, not as something to rebase mechanically.
Fail-first proof on main
Branch: https://github.com/CodexCoder21Organization/BuildTestEmbedded/tree/wip/sweep3-w2-r41-terminal-row-failfirst-on-main (0c2e3ac5). It contains tests only, with no product change.
Three of PR 1015's public-API tests were copied onto main unchanged. They fail 0/3, deterministically, in about 1.2 s each (scripts/test.bash --test <name>, 2026-09-24 06:01Z):
testTerminalCanceledRunPublishesCanonicalRowsBeforeSummary: "A canceled run summary must follow every canonical terminal test row; the feed still contains {} at sequence 3."testDeferredTerminalRunPublishesCanonicalRowsBeforeSummary: fails with the same message, "... the feed still contains {} at sequence 3."testTerminalRunPublishesXmlOnlyCanonicalRowsBeforeSummary: "... the feed still contains {projectionTest=RUNNING} at sequence 40". This is exactly the production symptom from run ed55d648.
The fix is done when all three pass on main, along with the invariant rows below re-expressed against the persisted projection.
Invariant table carried forward from PR 1015 (the spec)
| Invariant |
Public regression |
| Deferred persistence publishes each canonical terminal identity once |
testDeferredAlreadyPublishedTerminalRow |
| Startup cannot publish a summary ahead of a concurrent terminal group's rows |
testStartupSummaryOvertakesLiveTerminalGroupWithStartedScan |
| Coalescing preserves rows on their original side of a terminal summary |
testStartupRepairCoalescesRowsPastSummary |
| Legacy rows survive partial publication, archival, and a second restart |
testLegacyTerminalPrefixRestartLosesRows |
| Recounts and peer adoption publish canonical rows before the summary, using the current source fingerprint |
testRecountedTerminalRecoveryPublishesRowsBeforeSummary, testAdoptedTerminalRecoveryPublishesRowsBeforeSummary |
| Every actual written record boundary preserves the prefix, exact identity counts, summary order, and second-restart idempotence |
testTerminalProjectionRestartAtEveryWrittenRecordBoundary |
| A source that never existed stays distinct from an existing zero-byte source; restart publishes one terminal summary without invented rows or replacement markers |
testEmptyTerminalRepairDoesNotInventEventSource, testEmptyTerminalRepairInterruptedBeforeSummary; existing-file control testTerminalEmptyEventSourceKeepsItsFingerprint |
| Every accepted project/name/status identity is recognized by publication, retained lookup, coalescing and archival, including the empty legacy project name |
testLegacyBlankProjectTerminalIdentityPublishedOnce |
| Run disk/state/finalizer locks keep their owning pair and registry key reachable; idle pairs can be reclaimed only when no holder or waiting caller retains a lock |
testStartupArchiveDeleteMustNotRepublishDeletedRun pauses startup inside its disk boundary, archives reentrantly, and verifies deletion waits |
| Source selection and publication share disk and projection ownership; a deletion result never becomes a stale terminal summary |
The same archive/delete test checks the last run record is the delete tombstone; previous startup/live interleavings remain required |
| A terminal aggregation failure is selected once and published with the forensic canonical rows |
e2eAggregationInvariantFailureIsPublicAndExact |
Also carried forward from the 09-16 lane:
- A child process owns the writer until it is force-stopped.
- The parent waits for the child to exit before reopening the same directory.
- Dispatch renewal must release the run disk lock before it joins the writer that needs that lock.
Coordination requirement
BuildTestEmbedded PRs 1079, 1080, 1089 and 1092 are projection work owned by another live session. Before designing or changing projection publication:
- Check each of those PRs' state.
- Coordinate with their owners.
- Do not open a competing change to the same projection paths without agreeing on the ordering first.
Rules
- Raise no timeouts and reduce no iteration counts.
- Do not weaken the three fail-first assertions or any carried-forward invariant test.
- A test that fails is fixed in the product, never by changing the test.
Superseded
The original mission is moot. It asked for diagnosis of the restart-boundary 30 s timeout, the third-attempt retry, and historical-boundary proof, all against PR 1015's 09-16 head. Any such proof has to be redone against the re-ported code.
Original body (2026-09-16, stale)
Finish the restart timeout/retry diagnosis and historical boundary proof
Written 2026-09-16 11:18 UTC. RE-VERIFY: this is a time-boxed snapshot. Check the PR state, branch head and checks before proceeding; do not trust the prior RUNNING CI status.
Mission summary
Finish the terminal-row test proof for https://github.com/CodexCoder21Organization/BuildTestEmbedded/pull/1015. Production run https://buildtest.kotlin.build/run?id=ed55d648 showed COMPLETED while test rows remained RUNNING/PENDING. The implementation and behaviour reviews were already complete; this effort addresses missing mid-publication restart coverage, the bounded lock test's historical red, and a restart selector's earlier third-attempt pass. LU11 completed the historical lock proof but did not diagnose the earlier restart timeout or retry. No speculative product fix was made.
What was found and done
TEST DRAFT: CI is not green (test shards cancelled; aggregate build failed); restart timeout/retry diagnosis, historical boundary red and any post-fix gate remain incomplete.
Updated 2026-09-16 11:18 UTC. Reviewed lock baseline: 40b000c2fc27813bc64b1e2146519e07a18ef038. Verified product head: 88e23284b4e8238e2f1c6232b91382e27a92a732. LU11 made no product change; the inherited two-test draft remains on the remote branch.
| Finding |
Mechanism |
Runtime evidence |
| Bounded lock test |
The old terminal refresh joins a dispatch writer while retaining the per-run disk lock; the writer needs that same lock in appendTestEvent. Existing asynchronous retirement removes that cycle. |
testTerminalRefreshDoesNotJoinDispatchWriterUnderRunLock: historical runtime FAILED in 10931 ms with both named stacks; current head PASSED 1/1 first attempt in 6447 ms. |
| Restart at written-record boundaries |
No mechanism established for the prior 30000 ms failure. Per-record callback precedes batch force/public commit, so coverage concerns stopped-process recovery. |
testTerminalProjectionRestartAtEveryWrittenRecordBoundary: temporary phase-traced version PASSED 1/1 first attempt in 8634 ms, exercising first row, final row and summary plus repeated restart. Tracing removed. Historical runtime red still missing. |
| Original restart selector retry |
No mechanism established for the earlier third-attempt pass. |
testTerminalProjectionRecoveryPublishesRowsBeforeSummaryExactlyOnce: 20/20 baseline samples clean on first attempt (5 inherited from LU10, 15 from LU11 on the verified head). No fix or post-fix 20/20 claim. |
The exact historical runtime failure begins: java.lang.AssertionError: Terminal refresh formed the old lock cycle: the renewal held the per-run disk lock while joining the dispatch writer, and that writer needed the same lock inside appendTestEvent. Renewal stack:
The historical experiment removed only the second duplicate afterLiveTestCountsRead constructor property and its one-line comment at the old source lines 1398?1399, retained the first property and sole call, and copied the current lock test unchanged. This is a documented compilation correction, not an untouched-baseline claim. A requested rebase conflicted and was aborted to preserve the historical locking behavior. Both experimental edits were restored afterward. No historical experimental branch or lane-only coordinate was pushed.

The prior boundary failure remains Test 'testTerminalProjectionRestartAtEveryWrittenRecordBoundary' timed out after 30000ms; its console contained no boundary marker or useful child stack, only (jstack capture exceeded 1000ms; continuing with bounded child termination). The passing traced run did not reproduce it and the runner suppresses successful test console output. Read-only review did not establish a fixture or product lock cycle.
The original retry evidence remains WARNING: Flaky test: passed on attempt 3 of 3 after failing on attempt(s) 1, 2. The old raw log lacks both failed-attempt assertions. A conditional filename-sort problem was examined, but the cached build-rule result listed exactly one embedded JAR and neither bootstrap JAR supplied the service class; substitution is not established. Capture the failing attempt's child classpath and parent/child service code-source URLs if this candidate is revisited.
All test invocations used JAVA_TOOL_OPTIONS=-Xmx768m scripts/test.bash --test <selector> without local/remote override; a retry warning counts as failure. One invocation ran at a time. No timeout, iteration, assertion or production setting changed. No merge, enqueue, publication or deployment occurred.
CI snapshot re-verified at 11:18 UTC: OPEN/BLOCKED, four test shards CANCELLED after approximately 60 minutes (the workflow job limit), aggregate bld-build FAILURE because its prerequisite was cancelled. Exact aggregate error: The bld-build check requires all four test shards to succeed, but their combined result was 'cancelled'. Shard 1 ended during preparation without a test result file. The underlying preparation delay remains unexamined; no rerun was requested. CI run.
Exact-head boundary verification: after restoring the unmodified remote test, testTerminalProjectionRestartAtEveryWrittenRecordBoundary PASSED first attempt in 12941 ms alongside the canceled and deferred terminal-row selectors (3/3 total, no retry warning). This confirms current execution but does not explain the old failure.

The reviewed pre-lock commit is https://github.com/CodexCoder21Organization/BuildTestEmbedded/commit/40b000c2fc27813bc64b1e2146519e07a18ef038. The pending pre-ordering boundary candidate is https://github.com/CodexCoder21Organization/BuildTestEmbedded/commit/b8fc543ff7c2a56b29a06f2c9f4f16472a4e1be1; no historical boundary verdict was obtained. The earlier baseline selector samples 1?5 were at https://github.com/CodexCoder21Organization/BuildTestEmbedded/commit/bc024fa14345adddea223dbf4f7068a0f657cc0c with the same original selector; new samples 6 onward use the verified current head.
Evidence comments: https://github.com/CodexCoder21Organization/BuildTestEmbedded/pull/1015#issuecomment-5683859248 and https://github.com/CodexCoder21Organization/BuildTestEmbedded/pull/1015#issuecomment-5696354388. Prior LU10 checkpoint: https://github.com/CodexCoder21Organization/BuildTestEmbedded/pull/1015#issuecomment-5695545698. Earlier lane evidence remains at https://github.com/CodexCoder21Organization/PlanRepository/tree/lane/lu9-buildtest-embedded-pr1015-evidence-2026-09-16/handoffs/artifacts/buildtest-embedded-pr1015-lane-evidence-2026-09-16; LU11 did not alter that branch.
No code was deployed or published during LU11; all executed mutation commands concerned temporary local diagnostics, GitHub PR text and this handoff. The published artifact pin remains buildtest.embedded:buildtest-embedded:0.0.68290272. No merge or enqueue occurred. No lane logs, journals, diagnostic scripts, artifact outputs or lane-local coordinates were added to the product branch.
Next steps
- Preserve the completed lock result; do not spend another lane re-deriving it. Reproduction recipe: fresh checkout of the exact pre-lock commit above, apply the two-line correction below, copy
tests/testTerminalRefreshDoesNotJoinDispatchWriterUnderRunLock.kts from current remote head, then run the standard selector. The correction only removes a duplicate constructor declaration. Rebase of this historical tree was attempted and aborted due to conflicts, preserving the explicitly requested old locking behaviour.
- Diagnose the inherited boundary 30000 ms timeout using phase evidence and thread stacks from an actual failing execution. Temporary tracing passed once; that does not establish which boundary previously failed. The original failed output has no child marker or usable stack. The traced patch below is for investigation only and was restored before the final state.
- Obtain a runtime result from the pre-ordering boundary candidate. Keep all three stop points: first canonical row, last row before summary, summary; preserve public prefix sequences and exactly-once canonical rows before exactly one summary after restart, plus second-restart idempotence. If an old case legitimately passes, explain with evidence rather than altering it to manufacture a failure. The callback is after physical record write but before batch force/public commit: do not claim power-loss durability.
- Explain the original restart selector's observed third-attempt pass. The old log contains the warning but not either failed-attempt assertion. Baseline sampling results above are not a fix or refutation. A genuine restart-ordering defect gets a product fix; a fixture gap gets a public-seam correction. Write the mechanism and reproducer before editing. After a demonstrated fix obtain 20/20 first-attempt passes (a runner retry is failure), then the named neighbours.
- Address the final CI state without blind reruns. All four shards hit approximately 60 minutes; the aggregate check failed because the shards were cancelled. The inspected shard was still reporting preparation and produced no test result file. This is not evidence of a terminal-row test failure. No timeout increase or runner-size change is authorized.
- Fetch/rebase, check the PR is OPEN before any push, integrate any concurrent remote work, update the PR body and the existing evidence comment. Stop at final CI running as requested if that state can honestly be reached. Never merge, enqueue, publish or deploy.
Operational knowledge
Use a fresh checkout in the lane's own directory; do not reuse another lane's checkout. Read README, scripts/test.bash and https://github.com/CodexCoder21Organization/DocumentationRepository/blob/main/architecture/TESTING.md. Use JAVA_TOOL_OPTIONS=-Xmx768m scripts/test.bash --test <selector> --log /tmp/<evidence> with no local/remote flag. One invocation at a time; small named groups are permitted, never the full local suite. Record /proc/loadavg beside timings. The runner may retry internally; inspect both summary and per-test warning text. Do not add sleeps, retries, timeout increases, weakened assertions, mocks or reflection.
LU11 checkouts were fresh siblings .../scratchpad/workspace/LU11-BuildTestEmbedded and .../scratchpad/workspace/LU11-lock-baseline; final sweep details are in the findings appendix. Findings were maintained at .../scratchpad/out/LU11-findings.md; the complete useful content is copied below so continuation does not depend on that file surviving. Diagnostic patch and full runtime lock stacks are preserved in this handoff and PR comment, not the product repository. Raw console logs and dependency/build outputs are omitted from git by explicit brief; all results, timing/load metadata and relevant errors are retained here.
The working Coursier wrapper is in .../scratchpad/bin; /usr/local/bin/coursier is the wrong architecture. Java 21 is /opt/java/bin/java; gh is authenticated. gh pr edit failed on the Projects classic GraphQL field; REST PATCH with a JSON body preserves multiline text. rg is unavailable here. The report-challenge CLI is prohibited because it auto-merges records.
Local cold preparation consumed much of LU11: the first build-script attempt hit its existing 20-minute timeout under measured cgroup pressure; later product compilation completed, an accidental diagnostic insertion caused a test compilation error, the insertion was corrected, and the traced test passed. These preparation events are not runtime red proof or an explanation for the historical restart retry. Do not repeat the mistaken inference that load alone establishes a root cause.
A read-only independent reviewer found no concrete boundary-fixture cycle. Cancellation queues the later finalization without draining; getBuildRun does not drain; restart priming is demand-driven. The writer acknowledgement in the lock test is important because it proves the writer left its interruptible fixture wait before renewal proceeds into the old uninterruptible join.
The conditional child classpath hypothesis is unsupported: the old qualified embedded JAR fails the original filename-promoting regex, but R1015e's cached build result contains only one embedded JAR and neither bootstrap JAR contains BuildTestEmbeddedService. If revisiting, capture both code-source URLs and assembled child classpath in an actual failure; do not change the sorter and claim the retry is explained.

Incremental LU11 findings and exact historical lock failure
LU11 findings
OBSERVED: Started 2026-09-16. Brief: finish terminal-row proof for https://github.com/CodexCoder21Organization/BuildTestEmbedded/pull/1015. No merge, enqueue, publish, or deploy. One selector at a time with JAVA_TOOL_OPTIONS=-Xmx768m; no timeout increases, sleeps, or retries.
Plan:
- IN PROGRESS: Read handoff, prior findings, repository instructions and testing guidance; inspect restart-boundary failure.
- TODO: Explain and repair the restart-boundary test or demonstrated product defect, obtaining runtime red/green proof.
- TODO: Obtain lock test historical runtime red and finish restart-selector single-attempt samples and required neighbours.
- TODO: Review changes, checkpoint each milestone, update PR body and evidence comment; stop with final CI running.
OBSERVED: Findings and raw evidence will remain outside the product repository. At 75 minutes, checkpoint and record exact remaining work if the gate is unfinished.
OBSERVED (10:13 UTC): Fresh recursive checkout LU11-BuildTestEmbedded is at 88e23284b4e8238e2f1c6232b91382e27a92a732 after fetch/rebase. PR is OPEN/BLOCKED. Read handoff and claimed it as LU11; read README, runner and relevant testing guidance. Diagnostic phase prints are temporarily added to the boundary test (not a proposed product fix). Standard selector started 10:10:18 with loadavg 10.21 7.02 13.03; still in preparation. At 10:12 loadavg 12.64 8.84 12.98 and memory pressure full avg10 73.74. These are measurements, not a restart-failure mechanism.
OBSERVED: appendCommittedLines invokes the callback after newline write but before force and public commit. getBuildRun does not directly drain that writer. Independent read-only historical review is active; it will not build, mutate the tree, or run tests. No historical runtime red or new head verdict yet.
Invariant table retained from prior lane: child process owns the writer until forced stop; parent waits for exit before reopening the same directory. Every canonical terminal row appears once before one summary; a second restart adds nothing. Dispatch renewal must release the run disk lock before joining the writer that needs it. The three record-boundary cases and bounded lock test exercise these obligations without extending waits.
OBSERVED (10:23 UTC): The traced boundary selector remains in preparation, without test-body output, after about thirteen minutes. Its build-script child PID 1503855 is alive; a thread dump was requested to distinguish dependency preparation from test execution. The independent reviewer confirmed that removing one duplicate afterLiveTestCountsRead constructor property from exact historical 40b000 leaves its single callback call untouched. That narrow unrelated compile correction is the planned lock baseline, rather than counting the prior compilation error as runtime red. No additional compile has been launched.
INFER: The sampling and neighbour gate is at risk within this box because the first diagnostic run has not reached execution. This is not evidence about the failure's cause. Next concrete evidence remains the traced boundary phases and actual waiting stacks.
OBSERVED (10:31 UTC): Historical checkout LU11-lock-baseline was cloned fresh. Rebase onto latest main conflicts at f54e349e5 (README/build/source); aborted to preserve the exact requested old behavior. Removed only the duplicate callback doc/property pair at historical lines 1398?1399, retaining its first declaration and call. Copied current bounded lock test. No historical build has started. This experiment will explicitly be 40b000 plus the unrelated two-line compile correction, not a claim about an unmodified historical tree.
OBSERVED: PR body now begins TEST DRAFT and names the unresolved 30,000 ms failure and incomplete proof gates. Status report uploaded to the existing handoff. No product fix is proposed without the runtime phase evidence.
OBSERVED (10:32 UTC): First traced selector failed before test execution: BuildScriptTimeoutException: Build script timed out after 20m. Build rule elapsed 1250985 ms. Preparation thread dump at 10:29 was dependency class hashing; runner timeout dump later reached Kotlin analysis. No test-body phase ran, so this is neither boundary runtime evidence nor a selector sample. Complete runner failure text:

OBSERVED: Re-fetched/rebased unchanged product head and started a second diagnostic invocation after preparation completed its dependency work and host counters changed; no test was retried for a green result. Same timeout, heap, selector, and phase diagnostics.
OBSERVED (10:37 UTC): Second diagnostic invocation is still compiling. Original review log /tmp/R1015e-head-terminal-recovery.log was read: its only attempt evidence is the known third-attempt pass warning, with no failed-attempt assertion. The historical source reviewer finished: old refresh invokes synchronous orchestrator.close at line 14987; no static blocker was found in current bounded interleaving. I read the fix-flakey-test skill; the user brief's single-selector, no-merge and time-box rules continue to control. No speculation has been adopted as a fix.
OBSERVED (10:41 UTC): Second preparation remains active (build child 1510126: ~6m38 elapsed, 1m14 CPU at the last sample). memory.high is 6442450944 bytes. The test still has no runtime phase output. Independent reviewer is checking the boundary fixture's cancellation/startup wait paths read-only while the same one selector continues. No baseline samples have been added, no historical test executed, and no tested product change exists yet. This extends the stated gate risk; it is not a flake mechanism or a claim of completion.
OBSERVED (10:46 UTC): Independent boundary review completed without a concrete fixture cycle. cancelBuildRun's second finalization takes run/disk/projection locks and queues, but does not drain the held writer. The physical callback runs under publication and append-persistence locks, outside the journal lock; startup reconciliation drains child writes outside the disk lock. Thus the specific hypothesized second-finalization/getBuildRun cycle is unsupported by inspected source. The callback precedes FileChannel.force(false), so proof is process-stop survival of written records, not force-completed storage durability. Runtime phase/stack evidence remains necessary.
OBSERVED: Second preparation thread dump at 10:44:10 was in Kotlin FileBasedKotlinClass.create (dependency class loading), with main CPU46.9s over668.65s elapsed. By10:45:37 process-wide CPU had advanced to5m35s at12m36 elapsed; there is observable preparation progress, still no test verdict.
OBSERVED (10:49 UTC): Product compilation completed and cached on the second invocation. Test compilation then failed because my temporary phase-insertion script inserted a println inside JSONObject(assertNotNull(...)). This is my diagnostic edit error, not a product/test failure. Corrected that exact insertion, reviewed the diff, fetched/rebased again and launched the corrected trace. No runtime sample was counted. Full test compilation failure:

No retry warning. All three boundaries and second restarts are in this one function. The success log does not emit captured phase stdout, so it does not identify the inherited failure phase. Temporary tracing was removed, returning the product checkout to the inherited head. This does not explain or refute the previous intermittent30-second failure; no bug fix is claimed.
OBSERVED: Started the prepared historical lock selector at40b000 plus exactly the duplicate-property compile correction. This is the only active compile. The current head has no product edits to checkpoint; verified evidence will be preserved in PR/handoff instead of a lane-only repository commit.

The assertion captures renewal parked in DynamicDispatchOrchestrator.joinUninterruptibly and dispatch writer parked at BuildTestEmbeddedService.appendTestEvent. This is the required named lock cycle, not compilation failure or generic timeout. Current-head same selector now running.
The mechanism is synchronous orchestrator.close while terminal refresh still owns the run disk lock, and the evidence that demonstrates it is the two parked runtime stacks below.

OBSERVED (11:05 UTC): The independent historical classpath review found exactly one embedded service JAR in the R1015e cached build-rule result and no service class in either bootstrap JAR. The filename sorter would prefer a second plain-version JAR if one were present, but no such second JAR was found. INFER: this conditional issue does not establish the mechanism of the earlier third-attempt pass. The missing evidence remains the failing attempt's full error and assembled child classpath/code-source identities; no speculative change is justified.

RUNNING ? 2026-09-16 11:09 UTC. Original request: finish the terminal-row test proof for https://github.com/CodexCoder21Organization/BuildTestEmbedded/pull/1015, diagnose the restart timeout, obtain historical lock red, explain restart retries and complete the sampling and neighbour gates.
The PR is OPEN/BLOCKED at 88e23284b4e8238e2f1c6232b91382e27a92a732. Historical lock proof is now complete: the old synchronous close produced the named two-thread lock cycle in 10931 ms, and the current test passed first attempt in 6447 ms. The traced boundary matrix passed all three boundaries in 8634 ms; the earlier timeout is still unexplained. Fifteen of twenty baseline restart samples are clean first-attempt passes; sampling continues sequentially.
The existing implementation publishes canonical terminal rows before the terminal summary. It retires dispatch writers asynchronously so terminal adoption does not join a writer under the run lock. The boundary test checks a retained written prefix and exactly-once continuation across a stopped process and two restarts; no product fix was made in LU11.
CI is no longer running: all four shards were cancelled after about 60 minutes, matching the workflow's 60-minute job limit. The aggregate build check failed with: "The bld-build check requires all four test shards to succeed, but their combined result was 'cancelled'." Shard 1's final activity was buildscript preparation; no test result file was produced. The underlying preparation delay is not diagnosed, so no blind rerun was requested. Run: https://github.com/CodexCoder21Organization/BuildTestEmbedded/actions/runs/35081836092.
Delegated work at a glance: one read-only historical-review agent completed its review. It confirmed the old lock mechanism and reviewed the boundary fixture; its classpath investigation found only one embedded JAR in the earlier cached result, so it did not explain the retry. No delegate is running a build or editing files.
No user decision blocks local progress. Landing parallelization sweep: execution is deliberately sequential by the brief; remaining baseline samples own the one-runner gate, followed by small neighbour groups. Next steps are to finish the baseline, run the named neighbours within the box, update PR evidence and the existing handoff, and stop with every unresolved requirement stated explicitly.
Lessons: keep compilation corrections separate from historical runtime evidence; a clean sample does not refute a recorded retry; inspect the aggregate check's prerequisite before treating its failure as a product test failure.

OBSERVED (11:12 UTC): Baseline sampling is complete: 20/20 clean first-attempt invocations, consisting of five LU10 samples and fifteen LU11 samples (6?20). None had an internal runner retry warning. This is unchanged-code baseline evidence; no restart mechanism or post-fix proof is claimed. The same checkpoint comment was updated at https://github.com/CodexCoder21Organization/BuildTestEmbedded/pull/1015#issuecomment-5696354388. Small named neighbour groups are now running sequentially; the first includes the exact unmodified boundary test.
OBSERVED: Neighbour group 1: ['testTerminalProjectionRestartAtEveryWrittenRecordBoundary', 'testTerminalCanceledRunPublishesCanonicalRowsBeforeSummary', 'testDeferredTerminalRunPublishesCanonicalRowsBeforeSummary']; start 2026-09-16T11:11:46.577206+00:00; load 11.56 10.22 12.14 9/1467 1547840; wall 81.7s; exit 0; retry warning False; clean first-attempt pass True. Evidence /tmp/LU11-neighbours-1.log.
OBSERVED (11:13 UTC): Group 1 passed all 3 tests with no retry warning. The outside-repository driver initially stopped because its success-summary parser expected a closing parenthesis immediately after 3/3, while the runner prints ALL TESTS PASSED (3/3 tests completed successfully). The parser was corrected against the actual summary and per-test log; no test was rerun or changed. Remaining groups resume at group 2.
Plan checkpoint (11:14 UTC)
- DONE: read handoff, brief, repository instructions and testing guidance; fresh isolated checkouts.
- INCOMPLETE: diagnose previous boundary 30000 ms failure. Temporary traced test passed in 8634 ms; exact unmodified head passed in 12941 ms, but neither establishes the previous mechanism. Historical boundary red remains missing.
- DONE: bounded lock historical runtime red with both named stacks, same test first-attempt head green.
- DONE: original selector baseline 20/20 first-attempt samples. INCOMPLETE: explain old third-attempt pass and obtain deterministic reproducer/fix/post-fix20/20.
- IN PROGRESS: named neighbours; first group 3/3 clean.
- IN PROGRESS: final PR evidence and handoff update. CI has stopped with cancelled shards and prerequisite build failure; do not report it as running.

OBSERVED (11:18 UTC): All named neighbour groups completed: exact boundary matrix plus 13 neighbours, 14/14 first-attempt passes, no retry warning. The sample driver and neighbour driver have exited. Final fetch/rebase reports current branch up to date; PR is OPEN/BLOCKED on exact 88e23284b; push --force-with-lease reports Everything up-to-date and ls-remote confirms the same head. No new product commit was created because all diagnostic edits were restored. CI still has four CANCELLED shards and aggregate FAILURE. No extra test runs were started after this gate.
Where I stopped / what remains
PAUSED within the requested time box ? 2026-09-16 11:18 UTC. The task remains incomplete. Original request: finish terminal-row test proof, diagnose restart timeout/retry, obtain historical lock red, complete sampling and neighbour gates for https://github.com/CodexCoder21Organization/BuildTestEmbedded/pull/1015.
Verified progress: historical bounded lock test failed at the named lock cycle in 10931 ms; the same test passed first attempt on the head in 6447 ms. The exact unmodified boundary matrix passed first attempt in 12941 ms (the earlier temporary traced run passed in 8634 ms). The unchanged restart baseline reached 20/20 first-attempt passes: five inherited and fifteen new; no retry warning occurred. Completed neighbour selector results: 14 passed, detailed below.
The existing implementation publishes canonical terminal rows before the terminal summary. It retires dispatch writers asynchronously so a terminal mutation does not join a writer while holding the run lock. The draft restart test checks written-prefix retention and exactly-once continuation at three record boundaries; LU11 made no product change.
Still unresolved: the prior boundary 30000 ms failure's mechanism and historical boundary runtime red; the original third-attempt pass's mechanism and deterministic reproducer; any resulting fix and twenty post-fix first-attempt passes. A clean baseline is not a flake fix. Final CI-running stop condition is unmet: CI shards were cancelled at roughly the workflow's 60-minute limit, and the aggregate check failed on that cancellation. No blind rerun was requested and no test failure was inferred from the aggregate check.
PR state: OPEN/BLOCKED at https://github.com/CodexCoder21Organization/BuildTestEmbedded/commit/88e23284b4e8238e2f1c6232b91382e27a92a732. Branch remains the inherited remote head, with no new local product commit. Both checkouts were swept for uncommitted files, stashes and unpushed commits; none remain. No merge, enqueue, artifact publication or deployment occurred. The first line of the PR body identifies the incomplete proof.
Delegated work at a glance: one read-only historical review agent completed; no active delegates remain. It confirmed the historical lock mechanism and found no demonstrated boundary-fixture cycle or explanation for the original retry. Landing parallelization sweep: all local invocations were sequential; the named verification gate is complete, with no build left unattended.
Next steps: diagnose the two recorded restart failures, obtain historical boundary runtime evidence, prove the demonstrated fix with twenty clean first attempts and remaining neighbours, and resolve the stopped CI gate. No user decision was requested; continuation requires engineering work.
Handoff: https://www.handoff.wasmserver.com/handoffs/hf-2026-09-16-finish-the-terminal-row-test-proof-and-diagnose-restart-retries. Evidence: https://github.com/CodexCoder21Organization/BuildTestEmbedded/pull/1015#issuecomment-5696354388. Existing evidence comment and PR body updated. The handoff preserves the exact historical correction, full failure stacks, temporary trace patch, timings/load and remaining requirements.
Lessons: preserve the old runtime mechanism while isolating unrelated compilation repairs; first-attempt baseline passes cannot explain a recorded retry; distinguish preparation/CI prerequisite failures from product test failures.
