Every in-flight branch is pushed and listed in the body; briefs, continuation notes, review ledger and queue order are archived at PlanRepository branch handoffs/artifacts/board-drain-2026-09-27. Four user decisions (ContainerNursery deploy, NetLab manager deploy, AiCliSupervisorManager journal migration, kotlin-build-ci 0.0.107 deploy) remain open. created: 2026-09-13T00:38:25.518Z completed: null dependencies:
Board drain, 2026-09-27 session (paused 18:30 UTC with lanes stopped)
RE-VERIFY BEFORE ACTING. Everything below is a snapshot at 2026-09-27 18:30 UTC. Re-check every PR with gh pr view <n> --repo CodexCoder21Organization/<repo> --json state,mergeStateStatus,headRefOid,statusCheckRollup, merge queues with the GraphQL pullRequest{isInMergeQueue mergeQueueEntry{position state}} query, the board with handoff-cli list, and buildtest runs at https://buildtest.kotlin.build/api/runs?limit=50.
Original request (verbatim, the active /goal)
"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). Parallelize with 6 workers. The work on one of the 6 parallel handoffs should be driven to completion before another is started." Follow-up: "Ensure you claim the handoffs that you are working on, skip handoffs that are already claimed in progress."
Why paused
All six delegate lanes stopped at 18:24 UTC and no new lane can be started at the moment; the orchestrator swept every lane checkout onto remote branches (table below), archived the session ledger, and paused. Nothing below is lost: every brief, continuation note, lane findings file, report and the queue order are on the archive branch https://github.com/CodexCoder21Organization/PlanRepository/tree/handoffs/artifacts/board-drain-2026-09-27 (handoffs/artifacts/board-drain-2026-09-27/: p*.md briefs, notes/<handoff-id>.md continuation notes, final-reviews.md review ledger, queue.txt queue order, lanes/<lane>/findings.md|final.md|report.md, dispatch.sh/pr-green-enqueue.sh/capacity-batch.sh scripts). Resume by reading final-reviews.md (chronological decisions) and queue.txt there, not by re-deriving.
Operating model that worked (keep it)
Six concurrent lanes pulled from queue.txt (one handoff each, driven to a terminal decision, notes/<id>.md appended to the brief); manual F-lanes handled one-question chunks (classify a single failing test on PR head vs main; rebase; coordinate fix). Orchestrator did every final review (ledger), enqueued via GraphQL only after a clean final review, and armed pr-green-enqueue.sh REPO NUM HEADSHA watchers. Constraints for lanes: never merge/enqueue/deploy/publish; one remote client + one local JVM per lane (6 GiB cgroup; remote clients cost ~900 MB); no local full suite; all PRs target main; evidence on evidence branches.
Decisions open for the user (asked in every report since 15:00 UTC, unanswered)
- Deploy ContainerNursery from main (https://github.com/CodexCoder21Organization/ContainerNursery/pull/634 merged 15:56 UTC; production still pre-fix; remote runs keep dying in droplet allocation with "listDroplets stalled for 30000ms"). Recommended yes.
- Deploy the NetLab manager from main (https://github.com/CodexCoder21Organization/NetLabManagerServer/pull/150 and https://github.com/CodexCoder21Organization/NetLabManagerServer/pull/151 merged). Recommended yes; the NetLab long-exec handoff then needs one NAT acceptance run.
- Migrate the two AiCliSupervisorManager tests that read state.json before close to an incremental journal (recommended yes with a post-close durability assertion).
- Deploy kotlin-build-ci 0.0.107 (merged). Recommended yes.

Then complete the W54/W57 journal-ownership handoff. |
| https://github.com/CodexCoder21Organization/ContainerNursery/pull/642 | 0867910e | all four checks GREEN at 18:45 UTC; final review CLEAN (test-harness fix, W94); enqueue REFUSED: merge conflicts with main (629 landed at coordinate 0.0.166 on the same build.kts lines) | mechanical rebase onto main keeping coordinate 0.0.167 (or the next unpublished), verify the range-diff is empty apart from build.kts, re-run the required check, enqueue. 641 then takes 0.0.168. |
| https://github.com/CodexCoder21Organization/ContainerNursery/pull/641 | 6832a2c8 | final review CLEAN except coordinate (0.0.151-f14-reaper-20260927 is below main's line) | apply https://github.com/CodexCoder21Organization/ContainerNursery/tree/wip/641-coordinate-F24 (0b1409a7, coordinate 0.0.167) onto the PR branch after rebasing on main (629 landed at 0.0.166); if 642 has taken 0.0.167 use 0.0.168; re-run required check; enqueue. |
| https://github.com/CodexCoder21Organization/ContainerNursery/pull/625 | 68cc6603 | required run green; CONFLICTING with main | rebase, re-run required check, enqueue (final review was clean at 68cc6603; re-check the range-diff after rebase). |
| https://github.com/CodexCoder21Organization/BuildTestRunner/pull/122 | aaefd0cb | REGRESSION confirmed by F22: testE2EWarmMemoryGateDeniesFourthAggregateReservation passes 4/4 on main, fails on the PR head; mechanism: closing a prepared lane interrupts its worker while a real warm child is parked and the launcher reports that close-origin InterruptedException as a failed test result |
F22's candidate fix is one commit on https://github.com/CodexCoder21Organization/BuildTestRunner/tree/wip/122-close-interrupt-F22 (b76d800f, "Treat parked warm child closure as cancellation", NOT gated). Needs a red-first public test for the close-origin interruption, the 40-selector gate, both reviews, then push to the PR branch. F22's invariant table is in lanes/F22/findings.md. |
| https://github.com/CodexCoder21Organization/ContainerNursery/pull/635 | 4b064886 | HELD: an actor outside this session pushed three commits 15:52–17:40 UTC (227-line server change); approval at 8c27fae4 void | do not touch until the branch is stable and green for 30 min; then full review round (both delegate reviews + final review) on the new head. |
| https://github.com/CodexCoder21Organization/BuildTestEmbedded/pull/1073 | db0c1ab6 (stale) | approval void; repaired source on https://github.com/CodexCoder21Organization/BuildTestEmbedded/tree/wip/1073-W92 (c2c10b5f) with a newly fixed ownership defect and two red-first regressions; broad batch on the pre-fix head 272/280 | continuation note notes/hf-2026-09-27-finish-tokened-ownership...md: classify the 8 failures on untouched main first (7 preparation/follower tests likely belong to the preparation-deadline work; 1 ambiguous-write cleanup), then the 128 gate + 943-selector inventory on c2c10b5f, then update the PR branch. |
| https://github.com/CodexCoder21Organization/BuildTestRunner/pull/123 (draft) and https://github.com/CodexCoder21Organization/BuildTestEmbedded/pull/1115 (draft) | 6aadfb82 / 809d49f3 | the preparation-deadline fix (root cause: BuildTestEmbedded prepares the shared module cache serially per rule; red test on wip/shared-preparation-cold-rule-budget-W85 @02d1bb8c) |
W93 found the runner tests spent their budget compiling unrelated fixtures and wrote per-scenario prepared fixtures (two test files on https://github.com/CodexCoder21Organization/BuildTestRunner/tree/wip/prepared-fixtures-W93 @a8ca2412, not gated). Finish runner-first (gate 6/6), then the coordinator PR, then un-draft both. |

final reviews clean; required runs die on "Shared workspace module cache preparation exceeded its deadline" | after the preparation fix lands and is deployed to buildtest: re-request kotlin.build (remote) and enqueue each on green (606/613 reviewed; 612/585 noenqueue flags in the file mean re-review first). |
| https://github.com/CodexCoder21Organization/kompile.executionenvironment.bridge.interface/pull/29 | d576333e | final review clean; required run fails on an upstream kompile-core defect (manager's published-rule lookup ignores the buildscript's embedded builtin build-kotlin-jvm facade; red-first reproducer at kompile-core repro/f17-builtin-jar-dispatch @cdaad936) |
F25's uncommitted fix-in-progress is snapshotted on https://github.com/CodexCoder21Organization/kompile-core/tree/wip/builtin-rule-lookup-F25 (9f7bd769: PublishedBuildRuleArtifacts.kt, Workspace.kt, three new tests; NOT built or run). Brief: pF25-kompile-core-builtin-rule-lookup.md. Then republish kompile-core, bump the pin in bridge 29, re-run.

queue.txt(20 more). Skipped:hf-2026-09-21-finish-the-final-consumer-gate-for-typed-rpc-transport-failures(claimed by sweep4-U606; re-triage if stale). Staged one-question briefs not yet launched:pF20(1078 supersede),pF26(BuildTestEmbedded replay dedup race behind 1109's shard-1 flake: a shutdown between the durable completion append and the spool-cursor advance lets restart replay a shard completion, and the fixture's attempt-less event defeats dedup),pF16(UrlResolver relay-teardown stress flake, full-suite-only, low priority). Claims: several handoffs still show claims by dead lane agent names (codex-W9x etc.); they cannot be released from another conversation and go stale after 60 minutes; claim over them.
Root causes established this session (verify, do not re-derive)
- buildtest "Shared workspace module cache preparation exceeded its deadline" on large workspaces = BuildTestEmbedded prepares the shared module cache serially per rule (red test above; challenge filed https://github.com/CodexCoder21Organization/PlanRepository/blob/main/challenges/2026-09-27-1558-buildtest-required-runs-for-large-workspaces-die-on-shared.md).
- bridge 29's "no build.kts declares package build.kotlin.jvm" = kompile-core manager 0.0.176's published-rule lookup ignores buildscript 0.0.43's embedded builtin build-kotlin-jvm 0.0.35 facade (reproducer above).
- ContainerNursery droplet-allocation deaths ("listDroplets stalled 30000ms", closed instance proxies) = the URL facade closing the shared backend bridge on any decoded application error; fixed by 634 (merged, NOT deployed: decision 1).
- 1109 shard-1 flake = pre-existing replay race (pF26). 635's slow-startup-deadline flake and 629's superseded-waiter behavior = both already implemented/fixed by ContainerNursery 636 (merged 12:21 UTC).
- 122's warm-memory-gate failure = a genuine regression of the PR (mechanism above).
Infrastructure notes
handoff-cli uploads intermittently fail at the transport ("ClosedChannel", "Stream closed"): retry with 45–90 s pacing. GitHub REST budget is shared across lanes (use GraphQL for PR state). gh pr edit fails on a projectCards GraphQL deprecation; PATCH repos/O/R/pulls/N with --input instead. Sandbox cgroup throttles at 6 GiB: gate lane launches on memory.pressure and kill waiting remote clients (server-side runs continue; read /api/test-results). Never edit a running bash script in place. Only one kotlin.build re-request per PR head; classify a single in-territory failure (PR head vs main) before any re-run.
