hfCN625 final report

Written 2026-10-06T05:25:45.898432+00:00; PR snapshots refreshed at approximately 05:18 UTC. Re-verify these snapshots before acting.

Original request and outcome

Bring the large-download/web-UI handoff to LANDABLE, OUTDATED or BLOCKED, with supervisor-owned final reviews and merge decisions. BLOCKED: the one prerequisite for the central ContainerNursery download repair is a reviewed and published foundation.url:resolver:0.0.1305 carrying the oversized-reply fix. Its owning change is https://github.com/CodexCoder21Organization/UrlResolver/pull/1161, still OPEN/BEHIND at 61e5ccb3b83e40edc573166ba07210864777225f. There is no merged commit for this change yet: it is nine commits ahead and two behind main. The coordinate must be published from its eventual reviewed main merge, not from an unmerged head. Publication is forbidden in this lane.

The handoff as a whole is worthwhile and not OUTDATED. The Dashboard, ProductionHealth and Docker upgrade merge steps are already done, but the central public download regression still fails. No PR in this report is claimed LANDABLE.

Finished verification and mechanism

The mechanism is that PersistentInterleavedResponseBudget.tryReserve in resolver 0.0.1259 rejects a valid single interleaved reply larger than its entire shared budget even when no other assembly is active, and the evidence is the unchanged public facade test failing with the exact 9,437,940-byte charge versus 7,340,032-byte available-budget rejection, plus the source at https://github.com/CodexCoder21Organization/UrlResolver/commit/9553becc209e2fee9c4505c88cfd8ff01ed29297.

The existing ContainerNursery fix moves forwarded byte arrays onto binary attachments. Its rebased client still applies the smaller persistent assembly budget to each reply. The upstream oversized-reply change must be merged and published before this dependency combination can deliver the required response.

Fresh clone is under the assigned workspace. README.md and AGENTS.md were read first.
Fetched and rebased https://github.com/CodexCoder21Organization/ContainerNursery/tree/wip/l625-rebase-large-response-20261004: HEAD stays 856eba5fcd18315586c678b0f93f435abe6785b5, already based on current main dab37c7890cb8787c3ea767219ed0ad8bccb1ea5.
The large-response test is identical to the original PR; UrlFacadeProvider is identical to main, retaining its bridge guard. No source was changed.
One unchanged local target: scripts/test.bash --local --test testUrlFacadeRpc_largeByteArrayResponseReachesOutsideClient --log <lane-file>, after fetch/rebase. Build rule PASS in 543119 ms; target FAILED in 8122 ms; 0 passed / 1 failed, command exit 1. Observed failure is 1/1 in this lane. This forces a fixed 9 MiB response through the public API on an idle connection; no host-specific tuning, payload reduction or bound change was used.
One earlier remote attempt connected with health=OK but never returned a run ID or test verdict. A client thread dump showed PersistentRpcConnection.doSendRequest → UrlProtocolBuildService.rpc → RemoteBuildWorkspace.submitBuildChunked; that owned client was stopped, exit 143. It is no test verdict. No CI was re-requested.
Resolver 0.0.1305 and 0.0.1307 POMs both return HTTP 404. Maven metadata latest/release is 0.0.1302. Its published jar was inspected with static javap bytecode: tryReserve still refuses bytes above available capacity and has no oversized slot. Current resolver main 4fe061512ba91888439a2cf10608631bb99b6121 retains the same code. The required repair is neither merged nor superseded by the latest artifact.
https://buildtest.kotlin.build/api/test-results?id=9b90248d&page=1 returns complete=true, totalCount=0, results=[] for the prerequisite PR's red required run. Every available result page is covered (one empty page). No test verdict or unrelated-flake exception can be established from that record.

Review scope and remaining gate

Dedicated test and code reads checked the public transport path, fixed full payload/hash oracle, dependency alignment and preservation of main's bridge guard, against https://github.com/CodexCoder21Organization/DocumentationRepository/blob/main/architecture/TESTING.md and https://github.com/CodexCoder21Organization/DocumentationRepository/blob/main/PHILOSOPHY.md (read in full). Handoff triage rules at https://github.com/CodexCoder21Organization/PlanRepository/blob/main/handoffs/README.md were also read. The scenario has no timing-inferred success oracle or added retry/sleep. Resource ownership was recorded in the findings.

These are prerequisite assessment reads, not clean LANDABLE reviews. The revert/fail-first, five local successful runs per new test, full remote test gate and final code/test review have not been claimed satisfied. Test fixture observations to check at the eventual landing head: cleanup catches and ignores failures, and some setup allocations precede its finalizer. The historical four passing bridge targets were not rerun or presented as fresh evidence. The central regression failed before any source change, so no additional test batch, force push or source PR update was justified.

The resolver image-list and protocol reader-ownership PR heads have advanced since the historical handoff; their own remote checks are now SUCCESS as shown above. That does not establish their lane review gate or artifact publication. The independent WUI preparation and later fleet follow-ups remain part of the preserved handoff; this BLOCKED outcome does not silently mark them done. No production state or previously claimed deployment was freshly verified, and no deployment is authorized in this lane. Earlier production provenance remains explicitly historical/unverified.

Next steps: have the supervisor finish the owning oversized-reply PR's reviews/required checks and merge decision, publish resolver 0.0.1305 from the resulting main commit through an authorized publisher, then repin/rebase ContainerNursery and run the unchanged download/bridge tests and the complete LANDABLE gate before the supervisor makes any landing or deployment decision.

Cleanup and reporting

No subagents or delegated invocations. Landing parallelization sweep: no LANDABLE result is asserted; the publication prerequisite cannot be executed here. No source changes, commits, pushes, artifact publications, merges, queue operations, restarts or deployments. All existing checkpoints stay on their remote branches. No source worktree changes, stashes or local-only commits remain. Build outputs, downloaded jars, logs and cache were not committed. All owned test clients and build processes are terminal; a final full ps scan will confirm no owned background process remains. No status cron tool is available, no recurring job was created, and reporting stops with this terminal lane result.

Lessons

Green checks on a conflicted historical head cannot establish that its rebased dependency combination works; exercise the unchanged public contract on the actual rebase.
Verify exact missing coordinates and the latest published artifact's behavior before declaring a publication prerequisite; a newer version number alone does not prove a fix was included.
Keep submission/CI evidence separate from test evidence: health=OK, a red check with zero results, or a cancelled client is no code verdict; the local full-message regression identifies this separate code failure.

STATUS: BLOCKED needs reviewed, merged, published foundation.url:resolver:0.0.1305 from the oversized-reply change before ContainerNursery download repair can be validated

Earlier handoff body (preserved historical snapshots)

Resolve the UrlResolver large-reply prerequisite, then land and deploy the ContainerNursery change

RE-VERIFY: 2026-10-04 14:34 UTC, lane L625. This is a write-time snapshot for https://github.com/CodexCoder21Organization/ContainerNursery/pull/625. Recheck PRs using gh pr view <url> --json state,mergeStateStatus,statusCheckRollup,mergedAt,headRefOid, refs with git ls-remote, and the live jar before any deployment. Prior multi-repository work is preserved below as earlier evidence, not refreshed by this lane.

Mission and verdict

The user asked to fix and verify Docker image downloads through the URL facade. This lane was specifically asked to rebase the original ContainerNursery PR while preserving main's bridge guard, run its large-response and bridge tests, push the source PR, and stop at the orchestrator merge gate. The expectation that the original green head could land after rebase is refuted by the unchanged public regression.

Verdict (e): remaining behavior repair is in excluded UrlResolver. The rebase is durable and four bridge tests pass, but its 9 MiB response fails against main's resolver 0.0.1259. No source-PR force push occurred. The PR remains at its original head, so its old green CI cannot justify merging the rebase. No test was weakened, payload reduced, budget increased, resolver downgraded, upstream repo modified, artifact published, PR merged/enqueued, service deployed, or handoff completed/released.

Verified mechanism and evidence

Original PR is OPEN/DIRTY at 68cc6603c59ef188e627131817d3a28d4648e1d6; all four old-head checks are SUCCESS, including https://buildtest.kotlin.build/run?id=ecc259a8. Main is dab37c7890cb8787c3ea767219ed0ad8bccb1ea5. Bridge guard https://github.com/CodexCoder21Organization/ContainerNursery/pull/634 is merged.
Faithful rebase keeps main's resolver 0.0.1259 and snapshot-27 libp2p and assigned protocol 0.0.547. Three successive conflicts were only Gradle comment/libp2p context. UrlFacadeProvider is identical to main; the large-response test is identical to the original PR. The nine historical commits, including empty historical CI-trigger commits, are preserved with the required attribution. No new rerun requested.
testUrlFacadeRpc_largeByteArrayResponseReachesOutsideClient fails 0/1 in 2.4 seconds after compilation, with exactly:

RPC request 'downloadTarball' failed: INTERNAL_ERROR - Interleaved response 'req-1' requires 9437940 bytes of reassembly budget, but the persistent response assembly budget has 7340032 of 7340032 bytes available across 0 active assemblies. The response was rejected before parsing its response envelope or allocating its attachments.

Source at resolver 0.0.1259's commit https://github.com/CodexCoder21Organization/UrlResolver/commit/9553becc209e2fee9c4505c88cfd8ff01ed29297 confirms the mechanism. PersistentInterleavedResponseBudget.byteLimit is MAX_CONCURRENT_PARSE_BYTES - 1 MiB; tryReserve rejects any reply requiring more than the available total even when no assembly is active. validateStartFrameEnvelope reserves attachment aggregate plus amplified envelope before decoding. The test's 9 MiB reply exceeds the 7 MiB budget. This is not a CI provisioning failure or a timeout.
Open upstream https://github.com/CodexCoder21Organization/UrlResolver/pull/1161 at 61e5ccb3b83e40edc573166ba07210864777225f independently documents the exact same ContainerNursery failure after https://github.com/CodexCoder21Organization/ContainerNursery/pull/632 moved main to resolver 0.0.1259. Its fix provides a separate oversized-reply slot. The branch declares resolver 0.0.1305, and both 0.0.1305 and 0.0.1307 POM endpoints returned HTTP 404 on 2026-10-04 14:30 UTC. This lane did not change, build or publish UrlResolver.
PR description refreshed using structured GitHub API PATCH, opening with the user's mission and handoff links, explaining supplied production provenance, the rebase, exact failure and passing neighbors, and ending with the required attribution line.

Targeted validation on the checkpoint

Commands: git fetch origin && git rebase origin/main before each target, followed by scripts/test.bash --local --test <name> --log <lane-local-file>. One target process at a time; outer command deadline 20 minutes, original test budgets unchanged. No whole local suite.

Target	Pass/fail
testUrlFacadeRpc_largeByteArrayResponseReachesOutsideClient	0 passed / 1 failed
testUrlFacadeRpc_applicationErrorPreservesConcurrentBridgeCalls	1 passed / 0 failed
testUrlFacadeRpc_applicationErrorContainingFailedToConnectDoesNotKillBackend	1 passed / 0 failed
testUrlFacadeRpc_applicationErrorContainingFailedToSendRequestDoesNotKillBackend	1 passed / 0 failed
testUrlFacadeRpc_transientStreamCloseDoesNotKillConformantBackend	1 passed / 0 failed

Total: 4 passed, 1 failed. Independent code/test review verified unchanged public TCP/libp2p large-response scenario, full size/hash checks, bridge sibling/witness/error/count/close coverage, and no source changes outside dependency context. No source-head push was appropriate after the public contract failed, so the source-head 20-minute CI observation step was not started; no new source-head check was requested or re-requested.

https://github.com/CodexCoder21Organization/ContainerNursery/tree/main	dab37c7890cb8787c3ea767219ed0ad8bccb1ea5	Contains merged bridge guard; still lacks large-response protocol pin

Deployed but not merged — supplied live provenance: the orchestrator's lane brief reports production ContainerNursery on shared host 198.199.106.165 runs a jar built from https://github.com/CodexCoder21Organization/ContainerNursery/commit/a2fc6415da7c9fec508ff8337f68e59ec7eff4dd, an earlier original-PR head using protocol 0.0.546 and older resolver. Git ancestry was verified: this commit is on the original remote branch and not on main. This lane did not query the live jar. Final PR uses protocol 0.0.547, a compatible conversion improvement. If the supplied provenance remains current, deploying main before reconciliation removes large-response behavior. Do not treat successful downloads with older clients as proof the newer persistent resolver accepts the same payload.

Remaining steps

Re-verify live PR/ref/artifact state. Have the owner of excluded UrlResolver finish its oversized-response fix and make a reviewed compatible artifact available; this lane cannot modify or publish that repository.
Resume the preserved ContainerNursery checkpoint, rebase on then-current main, use the reviewed published resolver while preserving protocol/bridge behavior, run unchanged large-response and four bridge tests, and confirm the original source PR is still open before any lease push.
Obtain new-head required kotlin.build (remote) evidence. The separate buildtest provisioning problem reported by the orchestrator is not diagnosed by this local regression; do not repeatedly request CI to hide either failure.
Orchestrator review and merge decision. No CI/branch-protection bypass.
Only after user authorization, deploy ContainerNursery from reconciled main and verify Docker image downloads with the deployed caller versions.
Continue the separately owned web UI work preserved below; this lane did not touch those branches or the replacement branch.

Operational notes and cleanup

The report-challenge skill automatically enqueues and merges, conflicting with this lane's hard no-merge/no-enqueue rule; friction is recorded here for the orchestrator rather than running it. No cron tool exists in this session; progress was appended/uploaded during the active turn. Compile emitted duplicate-class and old-pin warnings, but the runtime failure is the explicit resolver budget rejection, not a missing-class claim. No warning-driven dependency sweep was made. Lane-local logs/XML/jars/cache are excluded from source commits; actionable failure and recovery state are recorded here. Both clones are clean; no stash or local-only commit remains. All owned test commands have terminated normally.

Earlier multi-repository record (preserved; re-verify independently)

Finish ContainerNursery repin and web UI CI after dependency publication

RE-VERIFY: 2026-10-04T12:28:20.112954+00:00, lane L9. Historical deploy and root-cause claims below are write-time context. No merge, enqueue, deployment, artifact publication or handoff completion was performed.

Verdict (c): salvage part. The merged Dashboard task is obsolete; the independently fixable WUI harness and runtime dependency changes are durably pushed. The lane is BLOCKED rather than at a merge gate: resolver 0.0.1305/0.0.1307 and GithubProxy client 0.9.1 are unpublished, and no full remote suite verdict or new green required CI check was obtained. No PR source head was updated from the WIP checkpoints.

OBSERVED: Final source PR state was refreshed at 12:21 UTC, all WIP/replacement refs were checked by git ls-remote, and final Photo checkpoint 9121d3228f95a1c7f39b40efd8eef0b6ffdcaece was rechecked after its passing target. Exact unpublished POMs were rechecked at 12:13 UTC, all HTTP 404. Production deployment state remains unverified.

All four properly selected full remote suite attempts ended exit 124 at their 15-minute command guards without run IDs or test verdicts. Performance additionally logged two complete RelayException stacks. These are no-verdict commands, not passing suites or proven test failures. No suite was rerun hoping for green. No full local suite was launched. The Photo full suite snapshot predates its final cleanup/heading correction; the final head has targeted evidence only. Existing test budgets and iterations were retained.

Remaining items and exact blockers

Dashboard: already merged, required remote SUCCESS. No branch repair remains; deployment/version was not proven by the read returning interim 103 and zero body through its guard. Deployment is outside lane authorization.
CN: stopped exactly as instructed. Required resolver 0.0.1305 and 0.0.1307 remain unpublished; original PR is DIRTY, older source head has a green required check. Replacement branch is preserved, not rebased/repinned against absent artifacts.
Performance: compile mechanism reproduced and fixed; same target passes, independent review found no blocking issue. WIP only because full-suite/required-check gate is unresolved.
Fabric: existing sandbox scenario and no-javaslang claim verified; no source repair needed for that path. Required CI remains red; remote transport/provisioning mechanism not established in this excluded infrastructure scope.
Photo: copied-local-class and unwanted browser-download mechanisms reproduced and fixed. Final browser/RPC scenario and driver target pass. The newly added h1 assumption is refuted by source history: renderer h2 since https://github.com/CodexCoder21Organization/PhotoGenerationManagerWui/commit/d2f999d015d81e4047e4c524d22d2bf7d0666006, assertion h1 added in https://github.com/CodexCoder21Organization/PhotoGenerationManagerWui/commit/451900279bebd24e3a40686f057d259fffb5bd5d. Only that exact expected tag was corrected; no production visual change. Independent resource/cleanup review addressed failure paths.
Github: packaged runtime dependencies fixed and public-constructor regression passes. The sandbox constructor adaptation is pushed, but compatible client 0.9.1 must be published from GithubProxyServerService source that already uses API 0.12.0. No downstream API/assertion change was made to hide the mismatch.
ProductionHealth and Docker named upgrade PRs: already merged; no merge work remains. Historical deploy claims were not treated as fresh evidence.

The next authorized owner must publish the compatible resolver/client artifacts, then repin/rebase and verify CN and Github. Resolve the remote execution/check mechanism in its owning scope before relying on another full suite or required CI verdict. Adopt the WIP fixes only after full-suite verification, then leave any merge/deployment decision to the orchestrator. Dashboard, ProductionHealth and Docker merge tasks are obsolete.

Scope and tool findings

Deliberately left out: all writes to UrlResolver, UrlProtocol, BuildTest* and kompile* repositories; publication of resolver/client artifacts; merging, queueing, production deployment and handoff completion/release. Unstarted fleet upgrades mentioned in the historical body are outside this lane’s specifically named PR preparation scope. No timeout, stress iteration or assertion coverage was reduced. The Photo heading expectation was corrected to the equally exact established markup, with the erroneous premise refuted above.

Workarounds/findings: installed gh pr edit fails with deprecated GraphQL repository.pullRequest.projectCards; structured JSON through gh api PATCH successfully updated four PR descriptions. Remote clients printed health=OK but no run IDs/verdicts; stale fleet projection membership could not establish accepted/submitted status. Playwright initially lacked Chromium shared libraries; 27 Debian packages were extracted to lane-local storage and used through LD_LIBRARY_PATH, without a system install. Scenario top-level helper artifacts are a narrow exception to TESTING.md's inline-helper rule because they must compile into isolated child JVMs; they follow the explicit harness task and existing Fabric pattern. report-challenge automatically merges, which conflicts with the lane’s hard no-merge rule; this friction is preserved in the handoff/reports for the orchestrator to record centrally.

All modified repo worktrees are clean. Diffs contain source/build scripts and scenario tests only; no logs, XML, browser archives, Debian packages or build outputs were committed. Owned test/remote processes are terminal, prior owned Photo child JVMs were ended by exact PID, and the final ps check shows no owned lane JVMs. No check rerun, merge, enqueue, deploy, publication, hcli complete or release was performed.

Historical snapshot (2026-10-02, superseded by above)

Land the url:// large-download fix and finish the url:// web UI stack cleanup

RE-VERIFY before acting: everything below is a write-time snapshot (2026-10-02 21:40 UTC). Re-check each PR with gh pr view <n> --repo <owner>/<repo> --json state,mergeStateStatus,headRefOid,statusCheckRollup,mergedAt, each branch with git ls-remote, and the buildtest fleet with curl -s 'https://buildtest.kotlin.build/api/runs?limit=100' (judge by each run's own completedAt/status; the dashboard projection's upToDateAsOfEpochMs has been stale since 13:03 UTC).

Mission

The user reported that url:// web UI pages (for example https://screenshottest.nursery.wasmserver.com/session?id=sess-0e7a76ce-d8cc-423f-a3a5-f1664b893546) were very slow or failed to load and asked that the underlying cause be fixed, merged and deployed, then: "Fix all the problems, merge, deploy, verify everything is working before moving on to the next service/fix" (services needing a newer SJVM may simply be upgraded). Standing operating rule from the user: delegate heavy lifting to coding workers; the orchestrator keeps briefs, steering, final review and merge decisions.

What was found (root causes, with confidence)

Sandboxed url:// client slowness (fixed, deployed for two UIs): SJVM ≤0.0.46 serialized every class lookup on a mutex, so concurrent requests queued for tens of seconds. Remedy: move each web UI to SJVM 0.0.50 with resolver 0.0.1171 / protocol 0.0.503 (non-transitive) + jvm-libp2p 1.3.0-codexcoder21-snapshot-26 + clocks-simple 0.0.11 / clocks-hierarchical 0.0.6 + observable core-jvm 0.3.21 + slf4j-simple 2.0.9, pin the coursier launcher in scripts, align test-script pins, add one child-JVM sandboxed-connection test. Deployed and verified: ProductionHealthServiceWui (the ProductionHealthServiceWui change) and DockerBuildImageServiceWui 0.0.13. High confidence.
Large url:// downloads (deployed, unmerged): ContainerNursery's URL facade forwarded byte arrays as one JSON frame exceeding the 4 MiB awaited-response outbox; with protocol 0.0.546+ byte arrays travel as binary attachments. ContainerNursery the ContainerNursery change is deployed in production but DIRTY against main; replacement branch wip/K53-625-repin-protocol-568. Companion UrlResolver the UrlResolver change (single-slot oversized-reply lane). High confidence.
Image-list 503 in the Docker web UI (fix in progress, UrlResolver the UrlResolver change): the sandbox's bulk collection capture invoked every zero-argument method on returned handles, including downloadTarball(), so listing 47 images downloaded 47 tarballs. First round (lazy operations, live guest proxies instead of host reconstruction) is pushed and verified locally; measured cost of the all-lazy design on the production list is 37.7 s cold / 20.8 s warm (329 crossings), so the required next round captures the getter subset in one batched loop and keeps only operations lazy (target under 2 s warm). A further defect found: nested getter-only lists on the recursive path lose their close tracking (guard written, unverified). High confidence on mechanism; the partial-capture design is decided, not implemented.
Two readers on one RPC connection (fixed upstream in UrlProtocol, resolver side unstarted): UrlProtocol2 built with the overload taking an explicit Libp2pNetworkProvider starts the protocol's automatic reply reader and the resolver's reader on the same input; frames split and one reader reads {"re (0x7b227265) as length 2065855077. Reproduced 10/10 on UrlResolver main (protocol 0.0.551). UrlProtocol the UrlProtocol change adds RpcResponseReader.CALLER, an ownership guard and close-once; published as protocol 0.0.603. Deployed web UIs use the simple constructors and are not affected; only the new test harnesses were (they now use a scenario-owned Kotlin helper UrlProtocol2(bootstrapPeers = listOf(testPeer))). High confidence.
Dependency closure gap: resolver/protocol pinned non-transitively miss three declared runtime deps (VpnUrlRegistrarApiClient:vpn-url-registrar-client:0.0.1, VpnUrlRegistrarApi:vpn-url-registrar-api:0.0.1, com.squareup.okhttp3:okhttp:4.11.0; NoClassDefFoundError reproduced on the VPN namespace path); the deployed ProductionHealthServiceWui has the same gap (follow-up). io.javaslang 2.0.6 pair is declared but unreferenced (leave unpinned, record the scan). High confidence.
buildtest fleet provisioning outage 18:10–21:11+ UTC: coordinator ↔ droplet-service url:// transport failures (addSshKeyToDroplet timed out 30 s; createDropletAsync stalled 30 s; EOF "read 0 of 4 bytes"; "inbound admission has made it terminal"; all 10 shards "Shared workspace module cache preparation exceeded its deadline"). Five of our runs died with zero test failures. Mechanism NOT established (diagnosis lane was killed at stop). Challenge filed: https://github.com/CodexCoder21Organization/PlanRepository/blob/main/challenges/2026-10-02-1830-buildtest-required-check-fails-with-provisioning-deadline.md. Do not re-trigger blind; gate on measured fleet health.
Other recorded findings: GithubProxyWui home page is slow on both old and new stacks (27 s vs 32 s), a backend-data problem, not the sandbox; PrDashboardServiceServer's published client-resources 0.0.3 lacks the home-page pagination methods its server source (0.0.11) provides; PerformanceTest trend page 500; url://prdashboard container was not running earlier today.

Deployed or published but not merged

ContainerNursery production (host 198.199.106.165, launched by the root cron one-shot watchdog, CN_JAR in /root/cn-watchdog.sh) runs the the ContainerNursery change content (protocol 0.0.546+ binary attachments). Anyone deploying CN from main rolls the large-download fix back. Reconcile by landing the repinned the ContainerNursery change and redeploying from main.
foundation.url:protocol:0.0.603 is published (from UrlProtocol the UrlProtocol change, unmerged). foundation.url:resolver 0.0.1305 and 0.0.1307 are reserved by open PRs 1161/1169 and NOT published.
DockerBuildImageServiceWui 0.0.13 and ProductionHealthServiceWui (the ProductionHealthServiceWui change content) are deployed from merged main.

Next steps (in order)

Watch https://github.com/CodexCoder21Organization/PrDashboardServiceWui/pull/44 land (it is in the merge queue); then deploy it via the ContainerNursery CLI with a baseline capture and first-screen verification.
Establish fleet health (completed runs with no provisioning failures in a 15-minute window) before any re-trigger; diagnose the coordinator ↔ droplet-service transport failure (no restarts before the mechanism is verified; see memory notes buildtest-cleanup-verification-cancellation-fails-run-hides-droplet-service-stall, buildtest-provisioning-deadline-is-url-transport-response-loss, url-stack-root-causes-index).
Re-trigger the UrlResolver change (last allowed) and the PerformanceTestWui change once healthy; enqueue the UrlResolver change on green; publish resolver from main; repin and land CN the ContainerNursery change; redeploy CN from main; verify tarball download (8,736,768 bytes) through the Docker web UI.
Finish the UrlResolver change: verify the nested-owner guard (branch wip/r66-nested-owner-checkpoint-20261002, plus the stop snapshot wip/r74-stop-handoff-2026-10-02), implement getter-subset capture with the measured acceptance, re-review, final review, land, publish, repin Docker web UI and redeploy.
Resolver side of the single-reader fix (pin protocol 0.0.603, request the caller-owned reader before any read, per-rule fail-first tests from wip/rpc-stream-single-reader), review and land with UrlProtocol the UrlProtocol change.
Land and deploy PerformanceTestWui the PerformanceTestWui change, HardwareControlFabricWui the HardwareControlFabricWui change (after the rerun-failure question), PhotoGenerationManagerWui the PhotoGenerationManagerWui change; align GithubProxyWui the GithubProxyWui change's harness and investigate its home-page cost; then MyLittleAgiWui, SnipdDownloaderWui, WebCronWui from the template at /tmp/claude-501/-code/acdecdda-adf8-425f-9efd-a7e4090e860a/scratchpad/p20-wui-upgrade-template.md (briefs p26–p28 v3 there; the scratchpad is session-local and may be wiped, the rules are also in the PR descriptions of Performance and Dashboard).
Follow-ups: ProductionHealthServiceWui closure pins; PrDashboardServiceServer client-resources publish; base64 review items (BuildTestServerService, BuildTestRunnerAgent, CivitDownloader, LambdaStore).

Reusable knowledge

Child-JVM sandboxed-client harness: locate the fat jar by content (remote places it as an extensionless qtbuild… file; the hashed .jar beside it is compiled test bytecode); build the protocol with UrlProtocol2(bootstrapPeers = listOf(testPeer)) via a scenario-owned Kotlin helper (the no-argument constructor loads production bootstrap peers; the 11-argument overload is not callable from Java; the provider overload triggers the two-reader bug on 0.0.1171/0.0.503); assert getKnownPeers() equals the test peer.
Six concurrent lanes compiling on this 16-core box saturate it; a shared flock on local-build.lock serializes tests (20-minute waits observed); budget lanes by lock demand and give each a push-anyway fallback.
The codex content filter stopped two launches of the reader-ownership brief; plain protocol vocabulary (no "inject/intercept/trace") passed.
A delegate's "full suite 18/22" on a loaded host is not evidence of a defect; the clean droplet is the arbiter, but never raise a bound.

Resolve the UrlResolver large-reply prerequisite, then land ContainerNursery and finish web UI checks
