Status report — 2026-10-09 04:40 UTC (RUNNING)

Original request: "Work through all open handoffs, delegating to codex/gpt for the heavy lifting, skip any handoffs which are already claimed. Make sure you (fable) do the final review before merging. Use your best judgement to decide how to proceed (handoffs and PRs may be obsolete or low quality or whatever) decide if they should be merged or closed or if anything from them can be salvaged. Drive them to completion. Parallelize with 6 workers who grab work off the queue (not waves). The work on one of the 6 parallel handoffs should be driven to completion before another is started."

🟡 Status: RUNNING. Six handoffs are claimed by this session (agent fable-hq-20261004), each with a codex lane on it, plus one Opus lane closing review findings on the handoff-service fix. Nothing on the path to DONE depends on the user. The three deploy recommendations at the end are for your decision only.

Progress since the 04:22 report

• Handoff-service fix https://github.com/CodexCoder21Organization/HandoffServiceServer/pull/30: the independent review (lane RV30b) finished at 04:33 with no blocking findings, four should-fix items and six nits. It verified from the protocol and ContainerNursery sources that the streamed reply is turned back into the same base64 shape by the facade's raw forwarding path and by the resolver's relay translation, so the command-line tool and the web UI see an unchanged reply; and it confirmed from the implementing lane's run logs that the storm test fails on both the old production code and the encode-once head (7 of 16 clients refused at the 32 MiB outbox ceiling) and passes on the streamed head. I routed all findings to the implementing lane, which has already implemented every one of them locally: a shared-array identity assertion for both request spellings, a new end-to-end test that drives a sandboxed client through a forwarding proxy with no jar of its own (the production path), a descriptive error instead of a silent wrong answer from the peer-to-peer request path, the compatibility check now run by the lazy-start bind, a cleared child environment, cleanup inside the try, and a health result assertion. Its three re-run tests are queued on the box's JVM slots; the five neighbour tests already passed first attempt on the current head. The required remote check on f7baaf34 is running (buildtest run af43a3f9), after its first attempt failed on relay infrastructure. My final review of f7baaf34 is void until the new head lands and will be redone against it.
• Lane L40 picked up my on-disk ruling: its selector controller now takes native thread snapshots before each held scenario's unchanged 30 s bound, and it has been waiting on a JVM-slot admission for 30 minutes to run them. It also assembled the production recurrence records for the description.
• Lane L47 has its repaired fixture executing under the original bound (first execution running; diagnostic variant and deliberate negative still without verdict). Nothing pushed to the PR yet.
• Lane L43 completed a source review of its candidate's metadata operations (no locks around callbacks, detached unions returned to callers) while its runtime gates wait on admission.
• Lane L49 ruled out an "interruption rollback" story and an equally unsupported "clock" story for a cancellation failure; its next step is a first-attempt run of the saved cancellation ordering probe, then forcing the retry-backoff boundary through the service's injected clock on old and new code rather than by host load.
• Lane L28 found that an existing callback test deliberately throws an interruption and continues on the same thread, which rules out a broad interrupt-flag restoration; its planned fix narrows to actual blocking-primitive interruptions. No source change yet; it stops test execution at 05:15 for its box.
• Lane L44 hardened its runner (stops only its own idle launcher, resumes it if a selector already acquired, optionally reuses a finished selector's staging workspace); no candidate code changed.
• Merge queues: https://github.com/CodexCoder21Organization/UrlProtocol/pull/647 holds at position 5, https://github.com/CodexCoder21Organization/UrlResolver/pull/1169 at 17; the re-requested check on https://github.com/CodexCoder21Organization/UrlProtocol/pull/649 has been in progress for an hour (full-suite scale). Pool: 19 active, 0 pending.
• Handoff mirror: the 04:22 report reached all six handoffs.

Fixture proofs done; source review of the metadata operations written; runtime selector gates waiting on admission. Next checkpoint: first selector results.

⏳ Running - GPT 6.1-sol high - 52 minutes total time - 4 minutes since last update - Lane L47 run 6 on https://github.com/CodexCoder21Organization/kompile-buildscript/pull/87. Repaired fixture's first execution running under the original bound; diagnostic and deliberate-negative variants queued. Next checkpoint: the repaired and negative first-attempt verdicts.

⏳ Running - GPT 6-astra high - 1 hour 44 minutes total time - 2 minutes since last update - Lane L44 run 11 on https://github.com/CodexCoder21Organization/BuildTestEmbedded/pull/1130. Fail-first proof in hand; runner hardened; waiting on admission for the candidate selectors. Next checkpoint: the fix behind the proof, rebased onto current main.

⏳ Running - GPT 6.1-sol high - 1 hour 42 minutes total time - 1 minute since last update - Lane L49 run B on https://github.com/CodexCoder21Organization/BuildTestEmbedded/pull/1207. Two unsupported failure stories rejected; cancellation ordering probe next, then clock-driven boundary forcing. CHECKPOINT box 05:25. Next checkpoint: the probe's first-attempt result.

⏳ Running - GPT 6.1-sol high - 1 hour 41 minutes total time - 1 minute since last update - Lane L28 run 4 on interrupted projection snapshot readers. Source evidence narrowed the fix to blocking-primitive interruptions; remaining fail-first bodies run until 05:15. Next checkpoint: body results file and CHECKPOINT.

⏳ Running - GPT 6.1-sol high - 1 hour 39 minutes total time - 0 minutes since last update (log; findings file 20 minutes old) - Lane L40 run 12 on https://github.com/CodexCoder21Organization/BuildTestEmbedded/pull/1213. Adopted the ruling: controller takes native thread snapshots before the unchanged bound; 30 minutes in JVM-slot admission for the first held scenario. Next checkpoint: the first diagnostic execution's snapshots and verdict.

⏳ Running - Opus medium - 1 hour 46 minutes total time - 2 minutes since last update - Agent lane HSVC3 on https://github.com/CodexCoder21Organization/HandoffServiceServer/pull/30. Implemented all review items locally; three re-run tests queued on JVM slots; required check running on f7baaf34. Next checkpoint: new head pushed with per-test first-attempt results.

⚪ Not running (finished) - Opus medium - 12 minutes total time - 7 minutes since last update - Agent lane RV30b reviewed https://github.com/CodexCoder21Organization/HandoffServiceServer/pull/30 at f7baaf34: no blocking findings, four should-fix, six nits, compatibility verified from source. It skipped the base-run reproduction because the JVM-slot queue exceeded its 20-minute limit and relied on the implementing lane's logs for the fail-first evidence. Its findings were routed to HSVC3; nothing further is expected from it, and a fresh review runs on the new head.

Changes since last report: RV30b finished and its findings were routed; no lane died; L40 confirmed alive by its log after a quiet findings file.

How the fixes work

Handoff service: The service crashed in a loop because each client connection asked for its bytecode and the handler base64-encoded a 2 MB jar plus a 0.7 MB stdlib jar fresh every time, about 10 MB of garbage per request in a 128 MB heap, while a slow consumer left several replies queued unsent. The fix drops the base64 path entirely: the protocol answers the bytecode request itself with a small header plus the jar as one binary attachment that is the same array for every reply, so sixteen queued replies hold one copy and fit both the heap and the outbox ceiling. The deciding test launches the real server entry point in a child JVM with production heap flags, seeds 20 MB of handoff bodies through the public API, and has 16 raw wire clients hold their replies unread until the server has answered all of them; it fails on the old code and on encode-once, and passes on streamed.

BuildTestEmbedded lanes: Each lane repairs a fixture or production defect only after a first-attempt failing proof on the exact code path, through public setup rather than new test-only seams, then shows the fix passes while a deliberately broken variant still fails. No timeouts raised, no iterations lowered; each red check is classified caused-by-PR, pre-existing-on-main, or infrastructure before any re-request. Lanes never merge, enqueue, publish, or deploy.

Blockers

🟡 None requiring the user. Infrastructure friction only: seven lanes contend for the box's two JVM slots (admission waits now reach 30 minutes), the buildtest relay refused one upload session earlier, and the handoff service flaps. Standing deploy recommendations, your decision only: (1) deploy kotlin-build-ci 0.0.109; (2) deploy the buildtest coordinator after https://github.com/CodexCoder21Organization/BuildTestEmbedded/pull/1213 lands; (3) deploy the handoff service once https://github.com/CodexCoder21Organization/HandoffServiceServer/pull/30 lands and 0.0.28 is published.

Plan changes and self-check

No plan change. Progress is real: an independent review completed and its findings are already implemented, two more rulings took effect in lanes, and the queued PRs are moving. The JVM-slot contention is the throughput limit; the two slots are the correct bound for a 6 GiB container, so I am not raising it. Landing parallelization sweep: on https://github.com/CodexCoder21Organization/HandoffServiceServer/pull/30 CI runs on the current head while the next head is being prepared; the re-review and my final review are staged to start the moment it is pushed; the two queued PRs and the re-checked PR have only their runs left; the kompile-buildscript PR has no candidate head yet. No idle runnable gate.

Next steps: land the handoff-service fix after its new head passes CI, the re-review and my final review, publish 0.0.28, watch the three queued or re-checked PRs through to merge, drive the six lanes to READY_FOR_REVIEW, review and enqueue each green head, complete each handoff, then pull the next unclaimed handoffs onto free slots.

Top-three lessons learned

1. Reproduce the condition in the dump, not the traffic you imagine. A heap dump showing replies queued unsent names a slow consumer as the trigger; fast loopback clients can never create that state, so a storm test built from them passes on broken code. Read the dump for the condition and force it deterministically (clients that hold their reads); here that test rejected a fix that had passed every softer test.
2. Let the test choose between two fixes. When a cheaper fix (cache once) and a structural fix (stream a shared attachment) both look plausible, pre-register the deciding test and run both heads through it before writing the description; the cheaper fix failed on the outbox ceiling, which no code reading had flagged.
3. Judge a quiet lane by its log and its children, not by one file. A findings file 20 minutes stale looked like a stall, but the lane's transcript log was written seconds earlier and a 30-minute-old child controller was parked in admission doing exactly what the brief asked. Check the last-write time of every output the job owns before killing it.
