Every other lane's latest Mission, branch/PR rows and findings below are carried forward unchanged from the immediately preceding handoff-cli get.

Lane up604 exit ? local measurement and changed PR head

Remaining for this lane's requested measurement: execute testProtocolCloseReleasesQueuedServiceAcquisition ten times after a successful source build. Also monitor the already-running checks and review the newer PR head a8e1269c596e2dfcbd01ca47ca845381577be037. No merge, enqueue, deployment, restart, publication or handoff completion was performed. This lane reports INCOMPLETE, rather than claiming a measurement that did not execute.

Resource	Verified state	Evidence / next step
https://github.com/CodexCoder21Organization/UrlProtocol/pull/604	OPEN, head a8e1269c596e2dfcbd01ca47ca845381577be037, required bld-build SUCCESS; bld-all-tests and kotlin.build (remote) IN_PROGRESS; informational kompile check NEUTRAL	The branch advanced outside this lane. Fresh test action: https://github.com/CodexCoder21Organization/UrlProtocol/actions/runs/37009844187. Supervisor monitors existing checks; old green result does not validate this newer head.
Original assigned PR head 6520853b0964280da0bb15088ed567fc88cb89a9	Required checks all SUCCESS; build-watchman GREEN exit 0	Its only failed informational check was getBuildRuleResults conversion examining 10002 host values against limit 10001 followed by overall CI deadline. No current failing fixture test appeared in these checks. Full check error saved in the evidence branch.
https://github.com/CodexCoder21Organization/UrlProtocol/tree/wip/up604-2026-10-02	f0dffd011e6fb9de17e60ad8328359db56803b52 pushed, ls-remote matches	Evidence-only checkpoint based on main. handoffs/artifacts/up604-2026-10-02 contains findings, all ten main relay logs, full fixture build failure/compiler thread dumps, original check output, watcher result and report. No source changes.

OBSERVED: Clean main 78deea8c61311e47596dad9c99b72763292e70e8 ran testRelayMaterializationBudgetNeverExceedsHalfOfSmallHeap ten times locally with unchanged test code and parameters: 9 PASS / 1 FAIL (10% observed). Run 8 ended at the unchanged 30000ms total-test runner deadline during the real chunk exchange. The first sampled stack was StringBuilderWriter.write -> JSONObject.write -> jsonWireBytes -> RelayStreamController.sendMessage -> exchange; the later sample was ProcessImpl.isAlive while forming the exchange response assertion message. Full RuntimeException stack and both thread dumps are preserved in up604-main-relay-8.log. This test's file blob is identical on main and original PR head.

INFER: Main independently exhibits the relay failure. The deadline ends the test, but these progressing samples do not establish why total time crossed it. No stuck-stream or host-load cause is claimed. This lane leaves this main test/source unchanged for the supervisor's decision; a deterministic underlying reproducer remains unproven.

OBSERVED: Fixture measurement: 0 executed tests, 0 PASS / 0 FAIL. The first original-head source build failed before test execution with BuildScriptTimeoutException: Build script timed out after 20m; full compiler/runner stacks saved. Its immediately following invocation was stopped before another build began. No deadline increased, iteration reduced, assertion weakened, test skipped or lock removed. The fixture already uses release.await() until explicit release, including finally; it is unchanged between 6520853b and a8e1269c. The historical fixed-duration hold correction is therefore already present.

INFER: There is no reproduced fixture bug justifying a new source edit. The missing ten-run measurement is recorded explicitly; it cannot be inferred from a failed source build. At the end of the ten main runs, less than eight minutes remained until the lane's 75-minute stop, so another full source compilation could not justify claiming the requested ten completed fixture runs. The PR version on original head was 0.0.591 versus main 0.0.569 and its rebase was up to date; this lane did not overwrite the branch after it advanced.

The lane's exact brief dispositions are in the pushed findings file. The original broad mission and all other lanes' latest rows follow.

RE-VERIFY BEFORE ACTING ? lane 000b-rev-up621 checked 2026-10-02 13:09 UTC. Only the assigned PR and review evidence branch were re-verified in this lane. All other shared lane rows and findings below remain their owners' write-time snapshots.

Lane 000b-rev-up621 review checkpoint ? 2026-10-02 13:14 UTC

Review of https://github.com/CodexCoder21Organization/UrlProtocol/pull/621 is in progress at 557f1fbe1b984501a65a638f791f06b921f3a61f. It is OPEN, and required bld-build, bld-all-tests and kotlin.build (remote) checks are SUCCESS. The informational kompile-remote-build failure is not being pursued. Latest commit and comment are October 1, older than two hours; no new concurrent session activity found.

The older snapshot-28 premise is superseded: this head pins snapshot-29, keeps plain child pauses, excludes Mplex lenders on the borrower's own physical connection, and suspends the minimum-progress stall clock during a borrow. The absolute deadline remains running. Current PR comments contain the owner's decisions on these behaviors.

The test-comprehensiveness pass has mapped fifteen behavioral/runtime-pin tests to the changed behavior. A first local batch is waiting for the shared compile lock using flock -w 1500; 0 tests executed so far. Three passing repetitions and independent fail-first verification remain. No CI/remote run submitted, and no source change made. Neighbor coverage inspection and then the implementation pass are next.

Lane 000a-rev-up618 review in progress (2026-10-02 13:04 UTC)

Mission: independent test-comprehensiveness review followed by adversarial code review at 25b29e542df44fac43068caf9eee362f0302fd5e. Delegate may prove/fix defects but never merge, enqueue, deploy, publish or complete this handoff.

Observed: OPEN at expected head, three required checks SUCCESS, newest commit October 1 04:09 UTC, no PR comments. Fresh clone/rebase unchanged. Fifteen added tests read; first all-fifteen local batch is compiling under shared flock. No remote run launched. Static review confirms exceptional root-stalled handoff still retains original buffers whose opaque direct NIO roots cannot be discovered by retained-capacity traversal. A real Yamux public-path draft reproducer is checkpointed; no production fix made and no behavioral failure yet claimed.

Tool friction: first submitStatusReport upload returned ambiguous outcome after EOF (read 0 of 4 bytes); local report retained. report-challenge CLI was not used because it automatically enqueues/merges, expressly forbidden for this lane.

Lane up604 milestone ? 2026-10-02 12:44 UTC

The September 30 remaining-work premise for the assigned PR is stale. The PR is OPEN at 6520853b0964280da0bb15088ed567fc88cb89a9. All required checks, bld-build, bld-all-tests and kotlin.build (remote), are SUCCESS; build-watchman exited 0 with RESULT: GREEN. The only red check is informational kotlin.build (kompile-remote-build): its getBuildRuleResults status read examined 10002 host values against limit 10001, then the build reached its overall deadline. The full error and stack trace are in the evidence branch. The old required run https://buildtest.kotlin.build/run?id=fe81020e now says Build run not found; its GitHub check still records success.

The held-dial fixture is already corrected on this head: release.await() keeps the dial held until the test releases it after close, or in finally. No source fix was added. Main is 78deea8c61311e47596dad9c99b72763292e70e8 (0.0.569); fetch/rebase was up to date, and the PR's 0.0.591 coordinate is already above main.

Fresh local measurement is incomplete. The first scripts/test.bash --local --test testProtocolCloseReleasesQueuedServiceAcquisition invocation failed while compiling buildMaven, before any test ran, with BuildScriptTimeoutException: Build script timed out after 20m (build rule failed in 1420812ms). Compiler thread dumps show parsing, type checking and bytecode generation. The remaining fixture iterations were stopped rather than repeating the same failed preparation. Counts: 0 tests passed, 0 tests failed, 1 failed build invocation; no fixture failure rate is available. The separate clean-main relay invocation is now running: scripts/test.bash --local --test testRelayMaterializationBudgetNeverExceedsHalfOfSmallHeap, targeting 10 runs, stopping on a preparation failure. Its verdict is pending.

A RUNNING progress report was uploaded with handoff-cli under fable-drain-4719c767. Initial get calls intermittently returned zero service peers, but health and the report upload succeeded, followed by this current get. No WUI mutation was used. No source assertions, iteration counts, timeouts or deadlines changed. No CI was submitted or re-requested; no PR merged/enqueued, artifact published, production service restarted/deployed, or route changed. Report-challenge's automatic enqueue/merge conflicts with this lane's explicit prohibition, so this tool friction is recorded in the findings instead.

Remaining for this lane: finish or explicitly record the main relay measurement, preserve its evidence, then return the unchanged required-green PR with the fixture-measurement gap named. The supervisor owns final review and the merge decision; the wider Mission below remains intact.

UrlProtocol main moved to 36977191 (0.0.551: #619, #623, #620, #625), so every PR in this family was DIRTY. 604, 611 and 605 were rebased onto 36977191 as one commit each (round history stays on their reviewed wip/*-ckpt-2026-09-27 branches).

Decision still open (for the orchestrator/user): whether a service send racing close should ALWAYS report the single closed message. Today several transport outcomes are pinned by 604's own tests; the 604 stress tests accept exactly those outcomes, only after a close has started.

Nothing deployed. No artifact published this session.

Re-check every pull request with gh pr view <n> --repo CodexCoder21Organization/<repo> --json state,mergeStateStatus,statusCheckRollup,headRefOid,mergedAt, every branch head with git ls-remote, and every build-service run by id (https://buildtest.kotlin.build/api/runs?limit=100, https://buildtest.kotlin.build/api/test-results?id=<run>&page=N&limit=100, raw log https://buildtest.kotlin.build/log/raw?id=<run>). The results API often serves stale snapshots; count only the exact selectors you asked for and never FILTERED_OUT rows.

Mission

Original request (2026-09-07): url:// bytecode fetches through the shared production host fail with Bytecode request for service '<name>' failed: Connection was closed by the remote peer ... Stream closed while reading message data (read N of M bytes). The user asked for a systemic fix, driven to completion: land every pull request and verify with the pre-registered production check (8 rounds ? 6 concurrent namecheapproxy.cli.MainKt list-domains calls to url://namecheap/; script repro_amplified.bash on PlanRepository branch wip/url-bytecode-stream-loss-handoff-2026-09-07 under handoffs/artifacts/2026-09-07-url-bytecode-stream-loss/; baseline 16/48 failures, pass gate 0/48). Deploy to production only if the user explicitly asks. Standing user instructions: "quota restored, finish this." (merge after the orchestrator's own final review; never ask for merge approval) and "We should fully understand [OUTBOX_FULL] before blindly changing this behavior" (answered ? see Decisions).

Decisions taken (with rationale) ? all still in force

1. OUTBOX_FULL stays as designed. The 4 MiB/connection, 8 MiB/process awaited-response budget and its refusal were added deliberately by https://github.com/CodexCoder21Organization/UrlProtocol/pull/430 to prevent a repeat of the 2026-04-27 ContainerNursery heap exhaustion. Server-side "wait instead of refuse" was refuted with evidence (a refused response cannot be retained inside the same budget; a separate waiting pool still refuses the 5th/6th 3 MB reader). The fix is client-side: the resolver replays a request marked idempotent (RPC_REQUEST_IDEMPOTENT_METADATA_KEY) when it receives the awaited-response OUTBOX_FULL error, from a frozen byte-identical frame, bounded by the request's own deadline. That is https://github.com/CodexCoder21Organization/UrlResolver/pull/1123.
2. 611's executor-termination finding is an upstream Netty lifecycle defect, not a 611 defect (SingleThreadIoEventLoop .cleanup destroys the I/O handler without closing registered channels; same on 4.2.18; present on main). Documented in 611's README with tests; upstream issue text drafted in the artifacts (out/F611r8-upstream-netty-issue.md), not filed.
3. Build-service outage fix design: keep the rule ordering that https://github.com/CodexCoder21Organization/BuildTestEmbedded/pull/1082 introduced (an existing test requires last-writer semantics and no dependency graph exists) and remove the per-rule workspace copy/snapshot/merge for sequential dependents. Implemented on wip/FBTE2-ckpt-2026-09-27 but NOT opened as a PR: the lane's own review found that skipping the merge also skips required entry-type validation, and a regression test for that had no verdict when the lane hit its wall. Two competing fixes from another session exist: https://github.com/CodexCoder21Organization/BuildTestEmbedded/pull/1115 (one ordered workspace per runner; needs a BuildTestRunner publication) and https://github.com/CodexCoder21Organization/BuildTestEmbedded/pull/1116 (in-place preparation for sole rules). Whoever resumes picks one; the service was scheduling again at 17:49 UTC without any fix deployed, so this is no longer the critical path unless the 20-minute preparation deadline is hit again.
4. 1123's four full-suite failures are round-4 fixture mechanisms, not a deadline defect (lane X2u: 12/12 fail on head, 12/12 pass on main). The retirement test pins Thread.State.BLOCKED (intrinsic monitor) while the PR now uses a ReentrantLock (contention parks as WAITING); three deadline tests advance a manual clock by counting currentTimeMillis() reads, which the PR's added before-dispatch deadline checks consume earlier. The orchestrator authorised repairing the fixture MECHANISMS only (wait condition + state assertion move together to WAITING; virtual time driven from the observable transport event) while keeping every asserted contract ? error texts, budgets, counts, timeouts ? byte-for-byte; NOT authorised: removing any deadline check, resetting the deadline, restoring monitor contention. The user has been told and may veto before 1123 is enqueued.
5. Delegate briefs must never list process command lines (ps with an args column, pgrep -a, /proc/*/cmdline): on a shared box that dumps every other lane's brief into the transcript and three review lanes were ended by the delegate content filter that way. The rule is in briefs/common.md in the artifacts.

Where every pull request stands (live-verified 18:08 UTC; all OPEN, none merged this session)

Merge gate for each: delegate adversarial + test-comprehensiveness reviews at the FINAL head (void if the head changes), the orchestrator's final review (out/FINALREVIEW-<PR>-<sha>.md in the artifacts), kotlin.build (remote) green, then enqueue. Coordinates: foundation.url:protocol 0.0.534 is claimed by every UrlProtocol PR (lowest POM 404 at push ? re-probe); foundation.url:resolver 0.0.1262; kompile.executionenvironment:kompile-executionenvironment 0.0.41 is published (POM 200).

PlanRepository	wip/url-bytecode-stream-loss-handoff-2026-09-07	531dc36f	?	repro_amplified.bash; handoffs/artifacts/2026-09-07-url-bytecode-stream-loss/lanes-2026-09-27/ = every lane's findings, final message, review verdicts, the orchestrator's final reviews, all status reports, the orchestrator action log, and every brief (briefs/)	complete except the multi-MB transcript logs, deliberately omitted

Local-only leftovers on the /code box (scratchpad/workspace/lane-G2-598, lane-G2-604 with unresolved build.kts conflicts; probe test files in lane-RBfix10-baseline, lane-T2k-main-baseline; a jvm-libp2p clone in lane-RBfix3) are superseded probes from earlier rounds and were intentionally not pushed.

Deployed or published but not merged

kompile.executionenvironment:kompile-executionenvironment:0.0.41 is published on kotlin.directory from PR 72's head 375511d1, which is NOT on main; anyone re-publishing from main would regress it. Nothing was deployed to any service this session (verified: no deploy or upload command ran in any lane; the shared BuildTest service still runs its pre-existing bundle).

Next steps (in order of leverage)

1. 604: check run ee47a4f5; green ? enqueue (it is fully review-complete).
2. 611: read run 7d79f890's raw log; outage ? re-request; test ? root-cause; then enqueue.
3. 605: resume from wip/F5v-ckpt-2026-09-27: 3 more remote repetitions, one PR push, both reviews at the new head, final review, remote green, enqueue.
4. 618 round 9 from briefs/pT2t.head.md; 621 round 4 from briefs/pC621b.head.md; 1123 round 7 from briefs/pX2v.head.md ? each: fail-first tests, fix, gate, one push, both reviews, final review, remote green, enqueue.
5. Lease PR 72 + 1112: re-reviews from briefs/pRLEASEadv3d.head.md (and a test re-review), final review, enqueue 72; then re-gate and push 1112's pin.
6. Build service: only if the preparation deadline recurs ? choose among wip/FBTE2-ckpt-2026-09-27, PR 1115 and PR 1116; ask the user before deploying.
7. 603 / 598: rebase after 618, one green required run each, enqueue.
8. Release: publish the protocol release containing the landed PRs, bump the resolver and namecheap-proxy-cli, declare the registrar's idempotent calls, ask before any deploy, re-run the 48-call check (gate 0/48).

Reusable / operational knowledge

• Lane tooling (all in the artifacts briefs/ + the notes): briefs = p<LANE>.head.md + common.md; one lane = one question; checkpoint to a non-PR wip/ branch at every milestone; push the PR branch exactly once per round; remote gates in batches of ?12 selectors, ?2 concurrent, collected by run id; a remote client with 0 executed tests after 15 minutes is terminated (run kept) and the batch runs locally under a memory slot then a global flock.
• Reviews are void the moment the head changes; a docs+tests-only delta needs only a test review.
• Bisect a deterministic head-fails/main-passes suite failure across the PR's own rounds before blaming the latest round (1123's four came from round 4; two of 605's predate round 15).
• The build-service results API lags the run list; the raw log is ground truth; "0 passed, 0 failed" after ~15 minutes means the run never executed tests (preparation deadline or droplet allocation failure), not a test verdict.
• Codex content filter: never dump process argument lists; describe crashes as "the process exited"; avoid "kill".

Lane 000a-rev-up618 proven ownership finding ? 2026-10-02T13:30:23.710052+00:00

RE-VERIFY: Snapshot 2026-10-02T13:30:23.710052+00:00; PR https://github.com/CodexCoder21Organization/UrlProtocol/pull/618 was verified OPEN at 25b29e542df44fac43068caf9eee362f0302fd5e with required checks green. No lane PR push yet.

OBSERVED: All fifteen original added tests passed locally once (15/15). New test testYamuxRootHandoffCopiesHiddenDirectBufferRoots fails on that production source: plain and read-only tiny NIO slices hiding 8 MiB direct roots remain retained while the real root loop is held and normal child allowance is full (expected refCnt [0,0], actual [1,1]). RootHandoffAcquired excludes copying, and visible ByteBuf capacity cannot discover the backing root.

Reproducer is durably pushed: https://github.com/CodexCoder21Organization/UrlProtocol/tree/wip/000a-rev-up618-2026-10-02 at e3f8b7d15ce8637c837ec7e0380076fd0e673241, git ls-remote verified. Proposed source/README fix copies all compact admissions while preserving captured permit counts, local commit 5605a10e pending shared-lock targeted verification before push. No source change to PR branch.

Next: verify fix, three repetitions and historical fail-first checks within budget, correct PR ownership text/add handoff links, one CI watch if pushed. Supervisor alone makes final review and merge decisions.

Note 2026-10-02 21:45 UTC from fable-drain-4719c767 (user stop request)

A lane on this handoff was stopped mid-work by a user stop request; it held no claim. Its findings are under https://github.com/CodexCoder21Organization/PlanRepository/tree/wip/fable-drain-4719c767-artifacts-2026-10-02/handoffs/artifacts/fable-drain-4719c767-2026-10-02/findings (kee72: kompile-executionenvironment PR 72 scoped verification complete, remote verdict was being watched; rev-bte1041: delegate review of https://github.com/CodexCoder21Organization/BuildTestEmbedded/pull/1041 at d2f274f8 had just started).
