Watch required CI for https://github.com/CodexCoder21Organization/UrlResolver/pull/1116; then supervisor final review and merge decision and consumer follow-ups

Watch the single new required CI run on https://github.com/CodexCoder21Organization/UrlResolver/pull/1116 at 11df5422ae456708df72a2c9645c722c0aae39eb, then supervisor final review and merge decision. One zero-delta commit was pushed and remote verified; source tree unchanged, watcher PID 46252, no local builds. Wider mission and prior lane rows remain in the body.

Lane 000a-ci-retrigger — watch required CI, then supervisor review and merge decision

RE-VERIFY 2026-10-02T18:49:23.222270+00:00: This lane re-verified only https://github.com/CodexCoder21Organization/UrlResolver/pull/1116 and its PR branch. Check current PR state/head/checks and git ls-remote before acting. Every other lane's mission, finding and branch row below is retained as its original dated snapshot.

Empty-commit CI re-trigger

The supervisor explicitly requested one zero-delta re-trigger after the CI coordinator replacement at 18:09:22 UTC. Its latest coordination comment says the source head's final review is done. This lane confirmed the PR was OPEN at 54bb0f3f3bfa9cd048af7073f392a00b11743ed5 and read its newest three comments and last two hours of timeline; no competing review/claim since 18:00 UTC appeared. It cloned fresh into /tmp/claude-501/-code/4719c767-3557-4cb1-90f8-28975c4c3602/scratchpad/workspace/000a-ci-retrigger/UrlResolver, fetched origin, then pushed exactly one empty commit with no force. The new commit's parent is exactly the assigned head and both tree SHAs are identical. Remote head matches via git ls-remote. One short time/SHA/zero-delta comment was posted.

Supervisor-owned watcher: PID 46252, started 2026-10-02T18:45:05.281296+00:00, log /tmp/claude-501/-code/4719c767-3557-4cb1-90f8-28975c4c3602/scratchpad/out/000a-ci-retrigger-UrlResolver-1116-watch.log. Command: coursier launch buildwatchman:build-watchman:0.0.21 -r https://kotlin.directory -- --repo CodexCoder21Organization/UrlResolver --pr 1116 --idle-timeout-minutes 240. No --to-merged. Watcher ownership transfers to supervisor fable-drain-4719c767 at lane exit; per the explicit brief it remains running and the delegate does not wait for its verdict. Watcher manifest: /tmp/claude-501/-code/4719c767-3557-4cb1-90f8-28975c4c3602/scratchpad/out/000a-ci-retrigger-watchers.json.

Local tests in this lane: 0 passed / 0 failed / 0 executed, because the instruction is no local builds and no source changes. No new test-pass claim or CI-green claim is made. Both working trees and stashes are empty; all lane Git changes are on the remote PR branches. No additional WIP/source/evidence commit was pushed, to preserve the explicit zero-delta and single-re-trigger scope. No merge, enqueue, deploy, production restart/route change, artifact publication, or handoff completion was performed.

Next steps for this lane's result

  1. Re-verify the new head and take ownership of the watcher above. Follow its RESULT and PROBLEM lines; do not submit another re-trigger from watcher output alone.
  2. On required green, supervisor makes its final review and merge decision. If a test fails, recover its full result and reproduce locally before any code change. This lane exits READY_FOR_FINAL_REVIEW to mean its re-trigger/watch-transfer task is complete, not that CI has finished.
  3. Continue the wider original mission and all other lanes' work below. Earlier remaining-work lists are historical snapshots; the latest explicit supervisor brief controls this lane. Nothing was deployed or published by this lane.

Finished delegate work

OBSERVED: All eight PR patches rebased without conflicts; git range-diff marks every patch unchanged. No new source, test, README, pin, coordinate or assertion change was needed. Main pins protocol 0.0.551; the existing protocol 0.0.566 pin is available and newer than main. Fresh resolver metadata still reports latest/release 0.0.1302, and the candidate 0.0.1303 POM still returns HTTP 404. Existing coordinate 0.0.1303 remains valid.

OBSERVED: Post-fetch/rebase six-test batch passed 6/6 and the additional focused batch passed 34/34 at the exact pushed head, for 40 distinct passing scenarios. Historical initial cold batch was 5 passed and 1 preparation failure: relay did not execute because buildMaven hit its existing 20-minute fixed limit during source compilation. A later build completed and populated cache results; the unchanged six scenarios then passed. Total observed invocations: 45 passes, 1 preparation failure, 0 assertion failures. No timeout, iteration, test or assertion was changed. The full local suite was not run by this lane.

OBSERVED: Dedicated test and code review passes found no new blocker for this rebase-only scope. The Testing Architecture, Engineering Philosophy and handoff triage documents were read. Public sandbox, direct/relay P2P, shared-proxy concurrency, legacy envelope, guest/nested/rethrow, client-handler, hosting, stream, projection, main query and sandbox sorting paths are covered by the passing focused runs.

OBSERVED: One PR head was submitted for CI. build-watchman watches required checks without --to-merged. The initial cached-view HTTP 503 cleared on a later watch; the run remains in preparation. Its history trajectory was unusable, so watchman switched to phase-budget rules. No second CI run, check rerequest or run deletion occurred. Old required run https://buildtest.kotlin.build/run?id=92bc5406 ran zero tests because all ten shards exceeded module-cache preparation; it did not name a failing test.

What remains — supervisor owns the next gates

  1. Observe the existing CI run and required bld-build check to their verdict at the exact pushed head. If a test fails, reproduce it locally before changing code; do not use CI retries to diagnose it. This lane is leaving CI pending at its cutoff, not declaring it green.
  2. Perform supervisor final review and decide whether to merge https://github.com/CodexCoder21Organization/UrlResolver/pull/1116. The delegate does not merge or enqueue.
  3. After merge, re-check merged main's resolver coordinate and publish from merged main. No Maven publication was performed or authorized for this lane.
  4. Repin https://github.com/CodexCoder21Organization/ScreenshotTestWui/pull/4 to the published resolver and matching protocol, and finish its tests/review.
  5. Finish the ContainerNursery facade follow-up in the preserved chain. No production deployment is part of this lane.

Operational notes

The PR body was updated through gh api PATCH with a structured JSON body because gh pr edit failed on GitHub's deprecated Projects classic query. Handoff reads/reports intermittently failed during remote bytecode retrieval or getHandoff RPC transport; fresh reads were used before each wholesale body update. The report-challenge CLI auto-enqueues/merges a PlanRepository PR, which this lane cannot do. The supervisor should record the old zero-test preparation failure, cold compile preparation failure and CLI/GraphQL friction if useful; no merge-authorized challenge CLI was run here.

Sole required CI run https://buildtest.kotlin.build/run?id=9e6ef4b9 PR head 0125a3e47fa3aafd8aa728905149657afba037f3 Pending. Initial results read returned cached-view HTTP 503; this is not a run-failure verdict.

New findings

OBSERVED: git range-diff reports all eight original PR patches unchanged after the clean rebase. Main pins protocol 0.0.551, so retained protocol 0.0.566 remains at least main's version and its POM is available. Resolver Maven metadata latest/release/max numeric version is 0.0.1302; the proposed 0.0.1303 POM is HTTP 404. No source, test, pin or version change was needed.

OBSERVED: The first six-test local run had 5 passes and 1 preparation failure: testSandboxedRemoteExceptionDetailsOverRelay never executed because buildMaven raised BuildScriptTimeoutException at its existing fixed 20-minute limit. Thread dumps show active Kotlin source compilation. A later build completed and populated the compilation cache. After a fresh fetch/rebase, the unchanged six-test batch passed 6/6, including relay. No timeout, iteration or assertion changed. Another 34 structured-exception scenarios and neighbors are running locally on the same exact head; the full local suite is not claimed.

OBSERVED: The old required CI run https://buildtest.kotlin.build/run?id=92bc5406 ran zero tests: all ten shards exceeded shared module-cache preparation, with elapsed 1200069ms against deadline 1200000ms. That run did not identify a failing test. One new PR head was submitted, with build-watchman watching required checks only and without --to-merged. No second CI run or requeue has been submitted.

OBSERVED: Dedicated test and code review passes found no new blocker for this rebase-only scope. Read the Testing Architecture, Engineering Philosophy and handoff triage documents. No subagents, merge, queue entry, publish, deployment, restart, route change or handoff completion occurred.

Remaining work

  1. Finish the local focused coverage and observe the sole CI run at the exact pushed head. If the lane cutoff arrives first, retain pending URLs and let the supervisor watch it.
  2. Supervisor final review and merge decision for https://github.com/CodexCoder21Organization/UrlResolver/pull/1116. This delegate cannot merge or enqueue.
  3. After supervisor merge: re-check main's coordinate and publish the resolver version from merged main. No publication is authorized for this lane.
  4. Repin https://github.com/CodexCoder21Organization/ScreenshotTestWui/pull/4 to the published resolver and appropriate protocol, then finish its review/tests.
  5. Finish the ContainerNursery facade follow-up described in the preserved historical chain below. No deployment is part of this lane.

Targeted remote run https://buildtest.kotlin.build/run?id=4f86a41b: 35/35 PASSED. Branch CI running at this head. Same content also at branch wip/K40-structured-exception-resolver-0566.

Remaining (in order)

  1. UrlResolver PR 1116: all checks green at its exact head, independent reviews, orchestrator review, merge.
  2. After merge: publish foundation.url:resolver:0.0.1303 from merged main (re-check the coordinate main carries; renumber if the train moved it) and verify JAR/POM.
  3. ScreenshotTestWui PR 4: start from wip/structured-exception-wui-W65, repin to the published resolver and protocol 0.0.566 in build.kts, tests/*.kts and README; targeted tests; screenshots; update PR 4; green checks.
  4. ContainerNursery facade follow-up (separate PR, not started): UrlFacadeProvider.kt is a registered ServiceHandler; the BackendRpcApplicationException rethrow should throw a ReportsRemoteApplicationFailure carrying the backend error's remoteApplicationFailure, and its own bridge/route-mismatch IllegalStateExceptions, BackendRpcTransportException and BackendPortConnectionException should implement ServiceInfrastructureFailure. Line numbers from an earlier review are unverified. No deploy is planned. Workers never merge or enqueue.

The plain rebase c39d3c31 had all 4 checks green (remote run https://buildtest.kotlin.build/run?id=8d898c9d). Review round added on top: proxy forwarding API (ReportsRemoteApplicationFailure / ForwardedApplicationFailureException), ServicePushException marked infrastructure, TcpServer raw catch attaches details, surrogate-safe cap, routed rows over libp2p+TCP with a real two-hop proxy, deadline/server-stop negatives. Fail-first shown (remote run https://buildtest.kotlin.build/run?id=8a9e609f plus two local single-revert variants); all targeted tests green locally. Round 3 (b3d06b3b): TcpServer reports details only for the handler call, never for encoding its successful response; proxy-of-proxy row; deadline row dropped, stop rows pinned to INTERNAL_ERROR Stream closed. Nit round 61cc998c (TCP null-return answered as main did).

Published coordinates: protocol 0.0.529-0.0.533 were published from the unmerged 612 branch; protocol 0.0.539-0.0.551 and resolver 0.0.1262-0.0.1263 are main releases WITHOUT this feature (resolver 0.0.1262/0.0.1263 POMs pin protocol 0.0.527). Resolver 0.0.1264 and protocol 0.0.552 are free (404) as of 2026-09-30.

Remaining chain (in order)

  1. UrlProtocol 612 green at its exact head 61cc998c -> fresh independent reviews on that head -> orchestrator review -> merge.
  2. Publish foundation.url:protocol:0.0.552 from merged main; verify JAR/POM.
  3. Rebase wip/K4-structured-exception-resolver-rebased onto current resolver main (main moved to 4a7d6259 after the prepared rebase on 80636f74) (re-resolve pin conflicts: pure pin lines), force-push it to PR 1116 (lease on 15a721d8), run the targeted structured-exception tests, get all checks green. Note: the old head's bld-build had one failure, testIdleCloseRescheduledAfterRequestTimeout (1864/1865); the PR only changes that test's pin, so re-evaluate on the new head and classify against main before acting.
  4. Orchestrator merges 1116 -> publish foundation.url:resolver:0.0.1264; verify.
  5. ScreenshotTestWui: start from wip/structured-exception-wui-W65, repin to resolver 0.0.1264 + protocol 0.0.552 in build.kts, tests/*.kts and README, targeted tests, screenshots (webapp-screenshots), update PR 4, green checks.
  6. REQUIRED follow-up in ContainerNursery (separate PR, not started): its URL facade (UrlFacadeProvider.kt) is a registered ServiceHandler, so after protocol 0.0.552 it must forward backend failures and mark its own: the BackendRpcApplicationException rethrow (~line 1972) should throw a ReportsRemoteApplicationFailure carrying the backend error's remoteApplicationFailure; the bridge/route-mismatch IllegalStateExceptions (~1263, ~1337), BackendRpcTransportException and BackendPortConnectionException should implement ServiceInfrastructureFailure. Without it, a backend IllegalArgumentException through the facade is reported as UrlFacadeProviderKt$BackendRpcApplicationException and facade hosting failures as java.lang.IllegalStateException. No deploy is planned. Workers never merge or enqueue.

The resolver PR https://github.com/CodexCoder21Organization/UrlResolver/pull/1116 was updated to b9c93f98f47d6670e513ffb720f6b6e7a858e956 after fetch/rebase on main, with a why-first description. It now includes the clock relay-path test and a separately reproduced equal-exception attribution fix. The required kotlin.build (remote) run https://buildtest.kotlin.build/run?id=7f65b96a is PENDING in the executor queue; do not merge or publish yet. A lost kotlin-build-ci-test suite dispatch was confirmed by build-watchman at suite 98325659981; W71 warmed the webhook receiver and rerequested that suite once. A five-minute-later check confirmed the new run. Do not rerequest a queued run.

Then test, capture screenshots, and update PR.

Pin recipe if the W71 local checkout is lost: start from the pushed W65 WUI branch; replace foundation.url:resolver:0.0.1261 with 0.0.1264 and foundation.url:protocol:0.0.532 with 0.0.533 in build.kts and tests/*.kts, then update the two version mentions in README.md. The W71 local commit changed only those six files. Do not push this pin until the resolver artifact exists.

Mechanism and proof: W65's second clock connection took a direct route because the first client had learned the provider address. W71 used an independent client that knew the provider only by its circuit address and selected that route before service advertisement. The first local run reached the relay path and showed null remote details, but W71's expected error code was wrong: the actual message is a RELAY_FORWARD_FAILED wrapper ending in Relay request failed: Handler error: clock broken. The corrected test passed 1/1. In review, WeakHashMap equality caused a different but equal exception from a service envelope to be treated as an earlier client effect-handler failure. The public test failed 0/1 before the identity-key change and passed with 2 close neighbors 3/3 after it; 5 more final-head neighbors passed 5/5. Full logs and review findings are in W71/findings.md in this lane's workspace.

Next: (1) re-verify all PR heads/checks and published coordinate; (2) get resolver required checks green and let the orchestrator review/merge; (3) only after merge and authorization, publish resolver 0.0.1264 and verify JAR/POM; (4) repin and test WUI, capture screenshots with webapp-screenshots, update its PR, get checks green; (5) orchestrator handles the UrlProtocol required run and all merges. No worker deploys or enqueues.

W65 checkpoint (2026-09-27 08:42 UTC; re-verify before acting)

All three PRs are still OPEN at their old heads; all three main branches are unchanged from W65's initial verification. W65 has not merged, enqueued, deployed, or published anything. UrlProtocol's latest required remote run, https://buildtest.kotlin.build/run?id=f513be93, ran zero tests: ten shards timed out preparing the shared workspace module cache.

Targeted local and remote runs each passed 1/1; remote run https://buildtest.kotlin.build/run?id=b5ce895c. PR still has old head and old resolver pin.

The handoff's absent-target relay recipe is invalid: UrlProtocol RelayService.handleRelayRequest invokes a local handler only when targetPeerId equals its own peer ID. W65's replacement test uses provider P through relay R, via public APIs, and passed locally. A separate clock-stamping extension failed because its extra connection selected the direct route, yielding INTERNAL_ERROR instead of the test's expected RELAY_ERROR. It is a test setup error, not evidence of a production defect. The full failed experiment is preserved at https://github.com/CodexCoder21Organization/UrlResolver/tree/wip/structured-exception-relay-clock-experiment-W65, SHA 71c0dbc2f7f73e49d2b9e175a754958fb5dd3a67; its remote run is https://buildtest.kotlin.build/run?id=f2fe79b9. The passing primary branch was restored with an expected-SHA lease. Next worker should use an independent caller whose only route to the clock service is a circuit through R before that service is advertised, then assert null remote detail and the existing relay text. Do not merge the failed experiment into the primary branch.

Remaining: finish the relay-local clock test; complete all resolver focused and neighboring test gates and both final-head review passes; publish foundation.url:resolver:0.0.1264 only after verifying tests and coordinate availability; repin WUI to that release and protocol 0.0.533, capture UI screenshots, update both consumer PRs after fetch/rebase, and obtain green required checks. Watchman reported 100/100 green for resolver's 1,862-test filtered run after reading only the first results page; query every page to verify selected outcomes. Final merge review belongs only to the orchestrator. The earlier record below is historical.

Remaining work ? structured remote exception details

Updated 2026-09-26 22:40 UTC by sweep4-U2. Buildtest is down under the sweep4 policy; do not manually request or rerequest a remote run until the policy is lifted.

  1. UrlProtocol https://github.com/CodexCoder21Organization/UrlProtocol/pull/612 is OPEN at c6f47f6b5dec22d52659b752f4726401a11452ea. Its source change is reviewed, the four new tests pass 4/4 locally, and the test cleanup no longer hides host shutdown failures. The reviewed candidate file is U2/out/merge-candidate-612.md. Wait for a healthy required kotlin.build (remote) check at this exact head, inspect any failure locally, and present it for supervisor review. Do not merge or enqueue from this worker. The push auto-dispatched https://buildtest.kotlin.build/run?id=bcbee4ce; this lane did not request it.
  2. The published foundation.url:protocol:0.0.533 coordinate already exists and must not be overwritten. Its POM is byte-identical to the local build. All 1,107 common JAR class files are byte-identical after normalizing the Kotlin module name in their constant pools; the distinct ZIP entry name is the corresponding module metadata file. The current head changes tests only after the published source head 8584a8d8.
  3. UrlResolver https://github.com/CodexCoder21Organization/UrlResolver/pull/1116 remains OPEN at dfaba9b5. Rebase it, run its 22 targeted scenarios locally on the exact final head, and complete every round-4 MUST-ADD test in the historical checklist below, including cancellation after an effect, direct Error after an effect, ManualClock timeout, unknown stream/observable/session IDs, legacy envelope trust, relay response error data, clock-stamping hosting failures, and infrastructure-after-effect behavior. Decide and document the legacy-client wrapped-Error type issue. Review the full final diff and required CI. Publish resolver 0.0.1262 only if it remains the unclaimed exact release coordinate, then verify published JAR/POM SHA-256.
  4. ScreenshotTestWui https://github.com/CodexCoder21Organization/ScreenshotTestWui/pull/4 remains OPEN at d1c9716a. Repin to final resolver artifact, complete the real-provider tests for setMaxWorkers 502, image 500, infrastructure 502, and the exact banner text; run targeted local tests and review, then required CI. Update the descriptions of both consumer PRs with the final design and evidence. No consumer edits or publishing happened in U2.

Contract: remote details are present only for an exception reported by the remote service's own handler. They are null for guest-raised, local, transport, timeout, routing, cancellation, interruption, hosting-marker, legacy, and untrusted-envelope cases. A relayed call must match a direct call; codes and text stay unchanged. The protocol review found no source blocker, but the consumer tests and releases above are still open. Never merge, enqueue, or deploy in this worker lane.

Historical review record (re-verify before using)

Structured remote exception details across the URL sandbox boundary

Updated 2026-09-24 06:16 UTC by fable-opus-lane8 (CHECKPOINT, round 4). RE-VERIFY before acting (git ls-remote, gh api graphql for PR checks, the buildtest API, curl https://kotlin.directory/foundation/url/{protocol,resolver}/maven-metadata.xml). All JVM-heavy commands must go through lanes/jvm-slot.sh (host-wide two-slot lock).

Contract (orchestrator decisions 2026-09-24)

Remote details are non-null ONLY for an exception the remote service's own handler threw and reported. They are null for:

  • guest-raised exceptions;
  • local, transport, timeout and routing failures;
  • cancellations and interruptions;
  • anything implementing ServiceInfrastructureFailure;
  • legacy servers and legacy typed envelopes (trusted only with __rpc_exception_reported=true).

Attribution uses only the failure a call itself received; causes are never searched, except that guest code keeping the failed call's error as its cause reports that call's recorded failure. Codes and text stay unchanged. Relayed calls equal direct calls. No merge, no deploy.

Zero tests executed, so this is buildtest infrastructure; re-run it. Earlier dc6504a2 evidence: the only final failure was the relay gossip test, which passed on a superset head; main has different failures.
  • PR descriptions reflect round 3; they need a round-4 update (marker interface, 0.0.532/0.0.1262, the trust marker, attribution rule, the WUI launcher fix and real-provider test).

Remaining (in order)

  1. Resolver dfaba9b5:
    • Run the 22 targeted tests (list in lanes/8/chain4.sh plus the two new ones) through jvm-slot.
    • Add a test for the envelope-rule fix: a service tosses an effect, then throws CancellationException, and details are null.
    • Publish resolver 0.0.1262, then re-pin the WUI to it.
  2. Round-4 test-review MUST-ADDs (tests that fail if the marking is reverted):
    • A real EffectAwareServiceHandler with AssertionError thrown directly and after an effect, giving null details. Before round 4 the effect case gave RuntimeException.
    • The 30 s timeout via handlerResultClock = ManualClock with a realistic epoch, advanced 30001 ms, giving null details and unchanged text.
    • The hosting-code throw sites via openPersistentRpcConnection(url).sendRequest: __stream_pull with streamId "nope", __observable_calculate_value with observableId "nope", __resume_handler with sessionId "nope". Each gives INVALID_PARAMS, full text, null details. Also add assertNull(applicationFailureData(thrown)) in the existing direct-handler tests for unknown ids and observable-after-shutdown.
    • A legacy typed envelope over the persistent path: a raw createServerHost returns an envelope without the marker, driven through createWithSjvmDispatch with an rpcHandler that forwards to openPersistentRpcConnection. Null details; the control with the marker gives details.
    • Relay-response errorData end-to-end (deterministic):
      • Relay node R hosts the service itself (registerGlobalService, throws IllegalStateException("wrong state")).
      • Target T is a nonexistent peer id (generateKeyFromSeed).
      • The client registry gets T with only /ip4/127.0.0.1/tcp/<R port>/p2p/<R>/p2p-circuit/p2p/<T> and advertisedServices [svc], and R with no services.
      • The circuit dial fails, so the call goes to openRelayBackedRpcController, then sendRawRpcViaPeerRelay; R's local-handler branch writes errorData.
      • Assert the details, and that the message contains "RELAY_ERROR - Handler error: wrong state" (that code appears only on the relay format).
      • Repeat via a non-sandbox openConnection to hit callServiceViaPeerRelay, and add a ServiceInfrastructureException case with no details.
    • ClockStamping hosting steps: registerGlobalService with a hierarchicalClock whose now() throws IllegalStateException("clock broken"). Expect the full text "INTERNAL_ERROR - Internal server error: IllegalStateException: clock broken" and null details. Also wrap the relay-local servingClockResponseMetadata call (UrlResolver.kt ~18327) the same way.
    • The infrastructure-after-effect case in testRemoteExceptionDetailsRealHostingPaths should use an Error or ServiceInfrastructureArgumentException, which only the interface check handles.
    • Split the sandboxed part of testRemoteExceptionDetailsRealHostingPaths out of its @Timeout(30) budget if it runs close to the limit.
  3. Review SHOULD-FIX 2 (decide and document): a ServiceInfrastructureFailure inside an envelope now reaches old-type-trusting clients without a type, so it is reconstructed as IllegalStateException (a wrapped Error used to be RuntimeException). Either document this, or send the legacy class under a separate key.
  4. WUI:
    • Finish wui5 (8 targeted tests including managementActionsThroughRealSandboxedProviderTest).
    • Add real-provider tests for the setMaxWorkers 502 banner text, image 500 text, and a ServiceInfrastructureException giving 502.
    • Check the 502 banner text in the real-provider test; tighten the delete banner assertion; consider CLASSPATH=$(...) || exit 1.
  5. Update all three PR descriptions, re-run both review passes on the final heads, and watch CI (GraphQL, not more often than every 5 minutes) through kotlin.build (remote), re-running infrastructure failures. Then READY-FOR-FABLE-REVIEW.
