Current continuation — perftest5 in progress

Snapshot2026-10-08 23:35UTC. RE-VERIFY live state before resuming. No merge, enqueue, publication, deployment or Server PR change is authorized by this slice.

Source milestone752cf56 is checkpointed at https://github.com/CodexCoder21Organization/PerformanceTestEmbedded/tree/wip/sol-perftest5. Evidence is at https://github.com/CodexCoder21Organization/PerformanceTestEmbedded/tree/checkpoint/perftest5-evidence/handoff-artifacts/perftest5. Findings there distinguish observation from inference and preserve exact commands/limits.

The suggested small unbuffered index writes are refuted by exact source/JFR: each index already writes one array. Large run files used90,391writes/642,905,684bytes; encode once/direct byte write reduces these to12,914 with the same byte total. Unchanged local test and deterministic write-count guard pass. Oversized BufferedWriter used67,563writes/553,399,128bytes; byte-segment reuse correction is committed and content/count verification is in progress. Original30s timed failures have not been reliably reproduced locally: do not call either cured based solely on write counts. Oversized child profiling shows parsing dominates; no production change is justified by this evidence alone.

Previous six final-head startup/recovery gates3/3 and mutation reds remain established in the prior snapshot. New remote5/5 gates, full70/70 first-attempt proof, PR branch/body update and CI green are incomplete. Baseline https://buildtest.kotlin.build/run?id=7ee209cc is PENDING for capacity; bounded local client/watch exited without verdict. Five connected Large gate clients are tracked under deadline00:28UTC; no verdict yet. PR https://github.com/CodexCoder21Organization/PerformanceTestEmbedded/pull/24 remains OPEN at the previouseb0bd4e head with required check red. Stop/checkpoint00:35UTC, hard end00:40UTC.

All prior source/evidence/server references and later publication/server work are retained below. This slice deployed/published nothing. Its untracked generated launcher uses kompile121 while source remains pinned65, as in the previous lane; no pinned65 credit is claimed.

Prior snapshot retained

Current continuation — perftest4 checkpoint

Written 2026-10-08 23:06 UTC. RE-VERIFY all PR, branch and CI state before acting. No merge, enqueue, publication, deployment or Server PR update is authorized in this round. This continuation stops at its mandatory timebox with two full-suite first-attempt fixture timing failures unresolved.

Final source is 427b14e2b82cf0149825732d74d0e031fd199095 at https://github.com/CodexCoder21Organization/PerformanceTestEmbedded/tree/wip/sol-perftest4. All six original/new startup and recovery gates pass first attempt 3/3 each on this exact head, using remote full12cf3702 plus selectedfbe28749/a7a0aa97 settled journals. Required synchronous-startup/stale-core mutation controls fail on the intended assertion3/3; additional final repair/discovery controls do likewise. Final source changes and independent review are explained in the final report below. Mutation branches were not pushed.

Full suite: 70/70 canonical pass, 68/70 first-attempt pass, 2 retry-only, 74 attempts. testLargeMetadataFitsRouteHeap and testOversizedNonterminalRecoveryStreams both hit their unchanged30,000ms outer test limit on first attempt; Large was writing the parent fixture index atline99, Oversized waiting for its child atline172. Both subsequently passed on the same droplet, as well as another attempt elsewhere. Total setup/probe duration crossing the outer limit is observed; the reason first-run work crosses it is not established. Do not increase limits, lower data sizes/counts, accept retry green as proof, or blame hardware without evidence. Full stacks and attempt journals are durable in https://github.com/CodexCoder21Organization/PerformanceTestEmbedded/tree/checkpoint/perftest4-evidence/handoff-artifacts/perftest4. Read perftest4-full-retry-stacks.txt and perftest4-full-suite-attempts-fresh.json.

The final recovery loadSummary(runId) lost its generation-checked publisher and could repair an index after delete finished. Baseline deterministic red3/3 proven, callback now retained in loadSummary(runFile(id),publish). The move-complete harness signal preceded finally cleanup; deterministic held-cleanup red3/3 led to observing/joining the worker before all unchanged artifact assertions. Additional public tests verify close during discovery and stale inspection failure after a newer acknowledged write. Resource fixture construction now uses BuildJar/BuildMavenArtifact2 rather than compiling empty Kotlin sources. Exact list order follows documented newest-first behavior. Independent code/test review cleared these changes, not the subsequently discovered timing failures.

Existing30-regression command initially25final/24first; repaired-six pass6/6first; all30 are covered by final full70 with the two timing failures above. Remote XML lacks attempt history and includes64filtered placeholders for selected runs. Settled API journals provide proof; derived verified XML preserves provenance. Source still pins kompile65 while untracked generated121 was used; do not claim the pinned launcher passed. All own tracked test/watch commands have exited; final own-checkout cleanup is recorded in the report.

Remaining work, in order:

1. Fresh-clone this wip4 source under workspace; read repository README/AGENTS and linked Testing/SlowServices documentation and this round's https://github.com/CodexCoder21Organization/PerformanceTestEmbedded/tree/checkpoint/perftest4-evidence/handoff-artifacts/perftest4/perftest4-final.md plus findings/review. Re-verify source/PR/ref state and fetch/rebase before builds.
2. Identify and reliably reproduce the mechanism behind the two30s fixture lifetime failures. Preserve every limit, data size, iteration and assertion. Diagnosis stays with the root agent. Do not blindly re-run CI; local or hermetic deterministic reproduction must establish the cause before a fix.
3. Correct at the responsible layer, prove previously failing test turns first-attempt green, complete relevant reviews, rerun required exact-head gates and full suite with the common remote-first policy. Record canonical, first-attempt and retry counts separately.
4. Only after validation, verify existing PR OPEN, fetch/rebase and run required tests, push its wip/sol-perftest2 branch with force-with-lease if needed. PATCH body only through gh api -X PATCH ... -F body=@file, re-read it, include why-first restart/60s production context, I1–I6 evidence and final gate table. Watch bounded tracked plain build-watchman --all-checks, never --to-merged. Stop at CI green; do not merge/enqueue/publish/deploy or touch Server PR.

Final report and findings contain all item states and links. No requested item is described as complete while its prerequisite remains unproven. Every prior source/evidence/server branch and later publication/server work is retained below; current no-publication rule supersedes earlier permissions.

Prior snapshot retained for provenance and all refs

Handoff: Validate incremental migration, finish Embedded CI, then publish after approval and merge

Written2026-10-08 21:25UTC. RE-VERIFY: This is a write-time snapshot. Check both linked PRs with gh pr view --json state,headRefOid,headRefName,statusCheckRollup; verify all remote branches with git ls-remote; check the0.0.20 POM before acting. No green claim applies to an untested later head.

Mission summary

Finish the cold-start fix for url://performancetest/. The provider previously scanned12,901 legacy runs / about1.7GB before binding and ContainerNursery stopped it at60seconds. This lane adds I6: production construction returns before directory discovery or body reads; indexes are built individually in the background; already-indexed runs remain served, progress is honest, and completed index units survive restart.

The current brief supersedes the earlier handoff's publication permission: do not merge/enqueue/deploy; do not publish0.0.20 until the orchestrator approves the Embedded PR and it has merged. Server preparation is checkpoint-only until that artifact exists. Keep both existing PRs. The mandatory80-minute stop is21:30UTC; this lane cannot declare completion while gates remain unrun.

What was found and done

1. Original upstream required remote run https://buildtest.kotlin.build/run?id=168ec2df has56passes/3failures. The three new fixtures each fail3/3 with 'Could not find the repository root from /root', before child launch. This excludes the proposed child-heap, repository-network, disk, and timeout explanations for those exact failures. A separate test-only artifact now packages each helper and the old0.0.15 runtime classpath; tests load resources and deliberately use an unrelated user.dir. This correction is prepared, but its green fixture gates are not yet run.
2. Existing I1–I5 and four earlier review fixes passed59/59 locally at eb0bd4e in perftest2. That evidence is preserved; it is not a pass for this lane's changed head. I4's demanded old-reader failure was correctly refuted previously because compatibility already worked.
3. I6 initial deterministic test failed: constructor performed32 forbidden legacy body reads. Fixed test passed1/1 at783456e, holding directory enumeration until construction returned, then holding a legacy read while the page served1of33 indexed files with incomplete progress, and finally verifying33 complete notes/log values. An index-before-bind mutation failed1/1 with the exact constructor-enumeration assertion. No timeout, heap, run count, or iteration limit was raised.
4. Added public SummaryMigrationProgress and SummaryIndexedRunPage for hosting JSON. Production constructors own discovery/migration; fake-runner disk constructors keep their synchronous compatibility contract. A named get can complete only its pending unit. Listing waits for bounded header discovery and does not force all bodies. ORCHESTRATOR nonterminal rows stay hidden until FAILED persistence completes. Reload retries through the coordinator.
5. Added isolated lifecycle tests for partial restart with no reread of completed legacy-a, complete notes/log/paged iteration values, delete during an open read, callback list/progress/close, malformed-first progress and repair/reload, indexed nonterminal recovery and one cleanup across restart, production READ_ONLY refresh, and delete during recovery.
6. The first new refresh gate failed at Kompile script validation before behavior: private returning helpers are still constrained. Corrected every helper to live inside its scenario, with local lambdas for returned values. That harness error is not target-red evidence.
7. Review regression gates then reached the actual defects: stale-core mutation failed Expected2 actual1; existing recovery failed because its per-run lock covered the held FAILED body rewrite, so public delete returned only after the5s read latch expired. Both are RED1/1. Checked draft applied at108d1d7: generation-checked atomic commit callbacks cover authority/dirty/projection writes and metadata repair; no run lock spans the recovery body. Close cancels discovery waiters, and post-I/O discovery mutations respect stop/generation checks. Missing/vanished/delete clear stale signatures. The corrected recovery green command exited124 while waiting admission; its empty console log confirms no test ran. No green credit.
8. Independent review verdict is NOT GREEN until the applied code and lifecycle cases pass. The latest draft semantics addressed its listed findings, but static review is not behavioral proof. The source branch still requires full local suite and the requested CI gate.
9. Server prep has all18 Embedded declarations at0.0.20, B1 public-constructor byte counting, S3 12,901-run512MiBSerialGC RPC heap check, I6 health/discovery/body latch, and indexed/total/failed/discovering/complete/stopped JSON on both paged RPCs. S1's fixed4MiB guard remains. Server source is untested, with no existing PR branch push.

Relevant PRs and remote branches

Published or deployed code

Nothing was published, merged, enqueued, or deployed by this lane. The0.0.20 POM returnedHTTP404 at21:26UTC. All current source is unmerged; there is no current binary to reuse. Earlier handoff language permitting publication before merge is superseded by the current explicit brief.

Exact remaining gates and steps

1. Read current final report and review ledger. Fresh-clone Embedded wip/sol-perftest3 under workspace, read README/AGENTS and Testing documentation, fetch/rebase latest main before each build. Verify the recorded recovery green result; do not count a slot-admission timeout as a test failure or a pass.
2. Run the targeted corrected refresh/recovery pair, then all lifecycle cases. Add any missing deterministic stop-during-discovery / per-file generation cases required by the independent review. Verify source authority digests and public iteration metadata after migration. I1–I5 values and bounds remain unchanged.
3. Complete the required first-attempt gate (20/20 where common-flake applies) and the three unrelated-cwd fixture gates. Run the entire Embedded suite locally at the exact committed head under a build slot and machine-wide full-suite.lock, as the latest perftest3 brief explicitly requires. Record counts. No reflection/mocks, skipped tests, larger heaps/timeouts, or smaller iteration counts.
4. Check the existing Embedded PR remains OPEN. Immediately fetch/rebase, rerun affected tests/full suite as required, then push the verified head to wip/sol-perftest2. Update its why-first body only via gh api -X PATCH ... -F body=@file, add I6/mutation/digest/restart and remote-cwd evidence, re-read body. End with the prescribed Claude Code attribution. Run tracked finite build-watchman --pr24 --repo CodexCoder21Organization/PerformanceTestEmbedded --all-checks, NEVER --to-merged. Stop at green for orchestrator review; no merge/enqueue.
5. Only after orchestrator approval AND its merge, use publish-maven-artifact skill to build/publish0.0.20 from the merged source and verify provenance/digest. This is not authorized merely by a green branch.
6. Once20 exists, fresh-clone server wip/sol-perftest3, fetch/rebase, run B1/S1/S3/I6 targeted cases and full suite with unchanged caps/counts. Verify existing server PR OPEN, then push tested head to its wip/sol-perftest1 branch and PATCH/re-read why-first body with rr24 evidence. Watch CI; no merge/enqueue/deploy.
7. Update this handoff in place and complete only when every remaining item is done or refuted with evidence. Always checkpoint remote source plus findings before stopping.

Operational knowledge

Shared build slots repeatedly delayed this lane; take mkdir build-slot-{1,2,3}, release only your slot in a trap,20min maximum admission, never hold a slot idle. The brief's explicit local-suite requirement supersedes the generic common remote-suite guidance here. One full local suite machine-wide.

The source scripts pin kompile-cli65; that launcher raises the inherited uncaught DiagnosticEffect locally. An untracked generated121 launcher was used, as in perftest2. Source pins were not changed; do not report the pinned launcher as passing. The common112 rule targets BuildTest, while this repository remains65. scripts/test.bash requires an explicit selector; --log alone exits without tests. Full suite uses --local --test . --log output.xml.

No public interface method was added merely for a test: native migration progress/page types are consumed by ServerService. Compiled test scripts prohibit top-level properties and declared return types/expression bodies on named functions; keep all helpers inside their scenario.

report-challenge CLI automatically merges its record, so it was not invoked under this lane's absolute no-merge rule. The known workaround and coordination delays are recorded here instead. Temporary mutation commits were never pushed and were restored with finite tracked scripts. Own checkouts are deleted after final remote verification; resume solely from linked branches.
