Problem

The November 8 Nightly, Interop, and Cache refresh runs expose several independent tooling and feature-isolation failures.

Approach

• Select rclone's executable output explicitly. The pinned package returns both man and out by default, which makes the constructed PATH invalid in both cache roots and refresh.
• Preserve the .der and .bin crypto validation data embedded by moq-webrtc when filtering Nix package sources.
• Gate moq-tokio's task guard, forwarding helper, and listener version list on the features that use them, so isolated builds compile with warnings denied.
• Initialize the relay HTTP test's crypto provider explicitly, matching the other TLS/reqwest tests when default crate features are disabled.
• Send the fake peer's transport parameters before awaiting the QMux datagram benchmark's handshake.
• Apply the existing JS routing decision to three missed lite-07 callers: drain migration, datagram interop, and browser publisher replacement. Remove drain from the nightly matrix, record datagrams as skipped in the interop report, and quarantine default browser replacement while preserving explicit local runs and the separate Firefox flake marker. The routing quest lists each restore point. Other media lifecycle cases still run.

Impact

• No public API or wire-format change.
• Restores nightly tooling and isolated compilation. Three JS lite-07 integration cases explicitly skip until the existing route-layer port lands.

Validation

• Reproduced rclone's multiple output paths; the explicit ^out selection returns one executable directory.
• Verified all five crypto validation files are present in the filtered Nix package source after the change; all five were absent before it.
• Reproduced the QMux benchmark's handshake timeout without peer parameters; all four backlog sizes complete after the fix.
• Rust formatting, Biome, test inventory, media observation unit tests, and workflow lint pass. Local drain/datagram recipes and explicit media replacement selection remain available for route-port validation.
• just rs tokio-features --all: passed, including every isolated transport build and the transport-less TLS regression test.
• just rs test -p moq-relay --no-default-features -E 'test(serve_hosts_merged_routes_alongside_the_defaults)': passed.
• Prior head bc2f314771666d362d1983a2be790dccef5ab423: just ci passed, including 7,568 Rust tests, JS checks/tests, workflow and inventory checks, and quest validation.
• Updated head 9c96400dd5d71a6adcb730500b7166eac93a5a04: quest gate nix develop --command just ci passed all selected checks and tests; quest check --base origin/main --branch fix/nightly-ci-2026-11-08 passed (604 documents).
• macOS package build and full scheduled benchmark/media suites have not been rerun locally.

Caused by

• moq-dev/moq#8173: used all default rclone outputs as one PATH entry.
• moq-dev/moq#8229: embedded validation data without preserving it in Nix's filtered sources.
• moq-dev/moq#8139: added the Tokio task guard without excluding feature sets that have no consumer.
• moq-dev/moq#8023: switched Rust's lite-07 routing wire; the agreed JS exclusions missed these callers.
• moq-dev/moq#7256: introduced the datagram benchmark without the peer transport-parameter handshake.
• Other feature-gating and test-provider assumptions predate this audit; no single PR accounts for all of them.

Alternatives

Widening default features would hide isolated-build failures. The HTTP test now initializes its provider explicitly; production provider behavior is unchanged. Implementing the JS route wire here would duplicate the existing routing quest. Extending timeouts or loosening performance/audio budgets would not fix their causes.

Follow-ups

• Restore the three lite-07 cases in the existing JS route-layer quest, alongside the other quarantined callers.
• Recommend planning investigation of the remaining Moxygen failures (start object 3 and integer extension across the two-relay lane), session benchmark handshake timeout, and paired performance regressions. These remain unresolved by this PR.
• Browser Opus bursty playback still exceeded its stalled-share budget; coordinate with moq-dev/moq#8058. Keep the budget unchanged.
• The mutation-test output-directory failure is already fixed on main by moq-dev/moq#8174; no duplicate change here.

Review

Rewritten by quest review after each round.

• Reviewer: Claude Code, claude-opus-5-5, medium effort
• Session: 50d502f3-a020-4cac-afa6-b39435e58262, round 1
• Head: 1b786cf, named in full once a round reports no findings
• Base: origin/main at 3e458ec
• Score: 8/10, The nightly fixes and lane quarantines are correct and follow decisions already settled in the quest; the remaining findings are low-severity consistency and docs cleanup.
• Findings, open until the next round settles them:
  • Low, sh/gh/test-inventory.allow:44: `test drain` quarantine has no allowlist entry naming its quest
  • Low, test/interop/README.md:558: README still says only Firefox's replacement case is left out
  • Low, test/interop/clients/js/media.ts:136: Firefox-only replacement filter duplicates the all-engine removal
  • Low, rs/moq-tokio/src/abort.rs:9: One cfg repeated on five items instead of fixing the module gate
  • Low, nix/overlay.nix:21: Source filter special-cases one vendor directory
  • Low, .github/workflows/interop.yml:225: Datagram tracks outcome is a hard-coded "skipped" literal

Low-severity round dispositions for head 9c96400dd5 (full SHA below):

1. Refuted: sh/gh/test-inventory.py:949-982 deliberately inventories recognizable test runners, test scripts, and browser drivers. test drain is outside that inventory; its restore point is explicitly tracked in quest/m2/cluster-routing/routes/js.md:34. Adding a non-orphan allowlist entry would not enforce its restoration.
2. Fixed: test/interop/README.md now explains the route-wire quarantine on every engine and the separate Firefox audio quarantine.
3. Refuted: media.ts:136 preserves the independent Firefox audio quarantine; removing the route-wire exclusion must not enable Firefox before its audio issue is fixed. The owning quest and README describe both restoration conditions.
4. Refuted: abort.rs:40-68 contains Detached, a separate net consumer. Gating the module only on the AbortOnDrop consumers would remove Detached from net-only builds.
5. Refuted: nix/overlay.nix:16-25 retains the specific required compile-time assets. Keeping every source-tree file broadens package inputs without a current missing asset; the suggested future fixture is hypothetical.
6. Refuted: the removed workflow step and explicit skipped report outcome are intentional, with both restore points recorded in the owning quest. Retaining a syntactic CI caller for the quarantined recipe obscures its orphan status in the inventory.

Reviewed-head continuation: 9c96400dd5d71a6adcb730500b7166eac93a5a04 contains only the low-severity documentation fix above; all six findings are fixed or refuted. No further round required by next finish.

Walkthrough

The interop and nightly workflows change how Datagram tracks and test drain are handled. The JavaScript media runner excludes replacement from default selections, while the documentation describes its quarantine. The test inventory and route-porting plan also change. Rust feature gates and a relay test setup are updated. Nix build recipes and source filtering change. The datagram benchmark sends recommended transport parameters before awaiting session readiness.

Merge Risk: Low · up to 9c964

The changes are mergeable with minor follow-up: report both Firefox quarantine reasons and document the working replacement-test command.

Full details: Title check

Explanation

The title "fix(ci): repair nightly tooling and skip pending JS route lanes" matches the main change. The diff repairs the nightly and interop CI tooling (rclone output selection, Nix source filtering, Tokio feature gating, relay test crypto provider, QMux benchmark handshake) and quarantines three JS lite-07 callers that are pending route-layer work. The title is specific and concise, and it does not cover every detail, which the criteria allow.

Full details: Description check

Explanation

The description explains the failing nightly, interop, and cache refresh runs and lists each fix by file area. It covers the rclone output selection, crypto validation file preservation, feature gating, relay test provider initialization, benchmark handshake change, and JS lite-07 quarantines. It also lists validation runs, related PRs, and follow-ups. It is clearly related to the changeset.

Full details: Docstring Coverage

Explanation

Docstring coverage is 60.00% which is insufficient. The required threshold is 80.00%. Docstring coverage is scoped to functions touched by this diff with cyclomatic complexity of at least 2. Documentation-only edits and deletions within surviving functions are included; unchanged diff context and fully deleted functions are excluded. Analyzed 5 functions across 7 files. (7 skipped: 7 unsupported.)

Automated review by review (OpenAI)

Reviewed bc2f314. No actionable findings. The rclone output selection, narrowly retained crypto fixtures, feature gates, explicit test provider, and benchmark peer handshake address their stated causes. The three route-wire exclusions follow the existing recorded decision, retain local opt-in paths, and have explicit restoration points rather than loosening budgets.

Verification: GitHub-only static review of the complete diff and relevant feature graph, call sites, benchmark, media selection, and routing plan. No Nix builds, isolated Rust builds, benchmarks, or scheduled integration suites were run; the reported validation results were not independently reproduced.

✅ No new issues found.

Reviewed changes

• rclone output selection — infra/nix/justfile now builds nixpkgs#rclone^out in both roots and refresh, so the constructed PATH no longer mixes in the man output path.
• Nix source filtering — nix/overlay.nix preserves .der/.bin files under rs/moq-webrtc/src/vendor/dimpl/crypto/validation/, which moq-webrtc embeds at compile time.
• Isolated moq-tokio builds — AbortOnDrop, Forward::configured, and the Server::new versions local are gated on exactly the features that consume them, matching their callers.
• JS lite-07 datagram lane quiesced — the Datagram tracks interop step is removed and hardcoded as skipped in the report, and datagram_tracks_javascript's ignore reason plus both test-inventory entries point at the routing quest.
• JS lite-07 drain lane quiesced — test drain leaves the nightly matrix while its local recipe stays available.
• JS lite-07 media replacement quiesced — default media runs delete the replacement case and record a QUARANTINE line, while explicit --cases replacement and the separate Firefox audio-tone marker are preserved.
• QMux datagram benchmark — the fake peer sends transport_parameters before await session.ready, fixing the handshake timeout.
• Relay test provider — serve_hosts_merged_routes_alongside_the_defaults installs the crypto provider explicitly, matching the crate's other TLS/reqwest tests.

Verification performed: the QMux datagram benchmark completes all four backlog sizes locally, and cargo check -p moq-tokio --no-default-features with -D warnings passes at each isolated feature set (net, qmux, tcp, websocket, uds, quic, driver). The two render-path fixes (rclone^out, filtered crypto data) and the browser media quarantine could not be executed here (no nix, no browser), but their logic matches the failure modes described.
