Settles CodeRabbit threads left unresolved when three PRs merged.

• #8304 r4508952357: spawn audit lists moq-video capture::open (PipeWire portal session task outlives the call).
• #8304 r4508952360: Client::connect/attach document that the end POST needs the runtime after the lease drops; await Consumer::reported().
• #8304 r4508952367: Server::broadcaster documents that a driver lasts while its Broadcaster is held.
• #8304 r4508952378: moq-webrtc runtime docs say routers spawn drivers and accept callers run Response::run.
• #8321 r4509107188: the session-close datagram test cleans up with onTestFinished, which runs on timeout, unlike finally.
• #8290 r4509395452: routes/js.md names just test media --media-cases replacement.
• #8290 r4509395464: the route-wire quarantine notice prints for default Firefox player runs too.

Public API: docs only. Wire: none.

Review

Rewritten by quest review after each round.

• Reviewer: Codex, gpt-6.1-sol, medium effort

• Head: 56dbb25
• Base: origin/main at 88fad4f
• Score: 9/10, No actionable regressions were found; the cleanup and quarantine-reporting changes are narrowly scoped and consistent with surrounding code, though builds and tests were not run as instructed.
• Findings: none

Automated review by review (OpenAI)

Reviewed head 56dbb25. No actionable findings in the seven-file change. Checked the timeout cleanup registration, default browser versus explicit/native media-case selection, and the runtime/driver lifetime documentation against the relevant implementations. The quarantine notice now covers default Firefox runs without changing explicit replacement runs.

Static source review only; no tests, builds, browser runs, or rustdoc checks executed.

✅ No new issues found.

Reviewed changes

• Interop quarantine notice (test/interop/clients/js/media.ts): reports the lite-07 route-wire quarantine on every default non-native run, including Firefox where replacement was already filtered out of selected; removal of the case stays a separate statement.
• Datagram track test cleanup (js/net/src/lite/datagram-tracks.test.ts): replaces the inline try/finally with onTestFinished, so the budget spy and the sessions are torn down even when the test times out with a wait still pending.
• Spawn audit (quest/m3/spawn-audit.md): adds moq-video capture::open for the Linux PipeWire portal session and drops the now-covered private SessionGuard example.
• Runtime and lease docs (rs/moq-auth/src/client.rs, rs/moq-hls/src/server/mod.rs, rs/moq-webrtc/src/lib.rs): records that the auth end POST runs after the lease drops, that an HLS driver lives while its Broadcaster or renditions are held, and that the bundled routers spawn WebRTC drivers while accept callers run Response::run.
• Routing quest doc (quest/m2/cluster-routing/routes/js.md): names the real just test media --media-cases replacement recipe.

Verified the two behavioral edits directly: a standalone Bun 1.4.4 probe confirms onTestFinished callbacks run on timeout (unlike finally), and bun test js/net/src/lite/datagram-tracks.test.ts passes 40/40. The doc-only claims also match the code (SessionGuard in rs/moq-video/src/capture/pipewire.rs, the Driver module docs in rs/moq-hls/src/export/driver.rs, Response::run call sites in rs/moq-webrtc/src/server/), and --media-cases is a real test/interop/interop.sh flag.

Walkthrough

The changes update JavaScript test cleanup and default fixture-backed media-case selection. They also revise documentation for media validation and Rust runtime, session, lease, broadcaster, and spawning lifetimes.

Merge Risk: Low · up to 56dbb

The changes are mergeable with a small documentation follow-up: portal-session cleanup requires Tokio to remain running after the stream drops. The remaining changes have no established behavioral regression.

Full details: Description check

Explanation

The description is related to the changeset. It lists each addressed CodeRabbit thread and the file it touches. It also states that the public API changes are docs only, that no wire changes exist, and that the checks pass. It has some noise, such as the generated-by footer and an embedded review block, but the content matches the changes in the summary.

Full details: Docstring Coverage

Explanation

Docstring coverage is 100.00% which is sufficient. 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 3 functions across 5 files. (2 skipped: 2 unsupported.)

Full details: Title check

Explanation

The title "fix: settle CodeRabbit findings left on merged PRs" is vague. It names the activity (settling review threads) but not the concrete changes, which are documentation and small test/script fixes across moq-video, moq-webrtc, moq-auth, moq-hls, and the JS and media test tooling. A teammate scanning history learns that review feedback was addressed but not what changed.

Resolution

Name the primary change in the title. For example: "docs: clarify runtime and task lifetimes; fix media replacement test handling". Keep the title to one short sentence.

Qualify the portal close task’s runtime requirement.

If the Tokio runtime shuts down before the close task runs, the task cannot call session.close(). The audit should state that the runtime must remain active for the close attempt.
