quest: plan follow-ups from the 2026-10-25 merge wave and Nightly - #6817
m0/nightly/windows-relay-expect.md [XS]: an unfulfilled #[expect] at relay.rs:871 breaks the Windows Nightly build.
m0/nightly/obs-audio-candidate.md [S]: the OBS failed-audio-candidate test passes under TSan and load, fixed at a reproduced cause. It absorbs main's duplicate m1/test-flakes-2/obs-audio-candidate.md, which this PR deletes.
m0/nightly/hls-poll-closed-gate.md [XS]: moq-hls Broadcaster::poll_closed, dead under --no-default-features, is gated on server, and the PR gate checks each crate's feature shapes in isolation. Workspace feature unification (moq-cli enables server) hides it from both moq-dev/moq#6703's gate and Nightly. Planned as a feature-shapes addition, but ci: check selected Rust feature shapes in the PR gate #6703 finished that quest first.
Edited quests
m2/uniffi-fork.md: the Dart negative-duration patch goes upstream, and the Go generator panic on a negative time.Duration gets fixed.

Walkthrough
This pull request adds and updates quest documentation across the m0, m1, and m2 milestones. The plans cover nightly test and build failures, feature gating, encoded-read APIs, HLS log redaction, Moxygen pinning, TS export ordering, export task ownership, timeline retirement, and UniFFI generator behavior.
Priority: Low
Merge Risk: Low · up to dd0c1
No runtime behavior changes are introduced, but several plans could direct incomplete or ineffective future fixes unless their contracts and acceptance conditions are clarified.

Pin the generator fix before removing the Go guard.
The required rust2 quest only requires a published crate and flake-input tag. It does not require that tag to contain the negative-duration generator fix. Record the fixed generator version or tag, and make the negative-duration test an acceptance condition before deleting the guard.

Update the “Negative durations” entry in the quest to identify the generator

an explicit acceptance condition before removing the Go wrapper guard.
Specify timeline-task replacement and external-cursor lifetime.
kio::Tasks cancels remaining tasks when its owner drops, so export shutdown is covered if the task set is export-owned. The current timeline watcher also aborts on reference replacement and remains alive after Broadcaster drops when an external recording cursor holds it. State how the migration preserves both rules and add tests for these transitions.

- Around line 15-18: Verify which derivation consumes moxygen-track-status.patch

stale deletion step from the Moxygen pin-bump instructions; otherwise retain the
step and identify the actual consumer.

- Around line 5-7: Update the SI export-to-import round-trip contract to define
“one PCR interval” as a valid forward PCR step within MAX_INTERVAL, and make the
test assert that the first SI section follows that step. Do not apply the
two-second catalog publication window or its variable-rate and EOF exceptions to
this SI test.

Included review availability: This review used your included allowance. Your plan provides up to 4 included reviews per hour; 2 remain after this review.
On the CodeRabbit nitpicks, all in 3e98919 except one:
hls-log-redaction.md: moved the current-state detail into Plan.
hls-export-kio.md: Plan now keeps the timeline watcher's two lifetime rules (replaced on a new reference, kept alive by a recording cursor past the Broadcaster) and tests both.
uniffi-fork.md: the Go guard goes in the PR that pins the fixed generator, with a negative-duration test through the Go binding.
moxygen-pin-bump.md Goal: kept the waiting state and the check in Goal. The quest guide has a waiting quest's Goal name its condition and how to check it, so it resurfaces at triage.
Fixed CodeRabbit's findings in 3e98919 (Moxygen patch source is the open test(ietf): moq-test conformance through a two-relay cluster #6729, SI's PCR interval is one MAX_INTERVAL step, re-init drops the recorder before Timelines::retire, plus three nitpicks); kept the Moxygen waiting state in Goal.
Merged main in 647922a. moq-dev/moq#6703 finished and deleted feature-shapes.md, so its new poll_closed item became its own XS quest, m0/nightly/hls-poll-closed.md. I confirmed the warning still reproduces on main with cargo check -p moq-hls --no-default-features --lib.
Codex reviewed 647922a with no findings; required CI passed; quest check passes (502 documents). Landing through the merge queue.
P2 — Establish the OBS failure cause before prescribing its wait (quest/m0/nightly/obs-audio-candidate.md:12–16). The audio-error callback holds ctx->mutex across both the failure log and candidate removal (cpp/obs/src/moq-source.cpp:705–713,760–766), and the assertion acquires that same mutex (cpp/obs/test/moq-source-test.cpp:1088–1089). It therefore cannot observe the proposed intermediate counter-before-clear state for that callback. The global counter can report other failures, and the assertion also requires active audio. Identify the failing conjunct and track/error, then derive the fix from that reproduction rather than assuming delayed candidate removal.
Direction: the focused follow-ups and reuse of existing redaction/read/retirement mechanisms are appropriate. The clarified PCR and watcher-lifetime contracts improve the plan; the base update preserves the remaining HLS feature-gating task separately.
Verification: static review of the plan changes and relevant source only. No tests, Nightly reruns, builds, or benchmarks run.
On the OpenAI P2 (OBS failure cause): agreed. The "Audio track error" log that bumps g_candidate_failures and the pending_audio clear both run under ctx->mutex, so the check cannot see counter-before-clear. ecbfb19 rewrites the quest to reproduce first, find the failing conjunct and the error that bumped the counter, then fix that cause. Sized up to S.
Merging main again brought in m1/test-flakes-2/obs-audio-candidate.md (from #6790) for the same test. I folded its evidence (#6711, the load reproduction from #6737) into the m0/nightly quest and removed the m1 copy, since the maintainer placed this Nightly failure in m0.
I dequeued the PR to push this; it will be re-landed after review of the new head.
The prior OBS diagnosis P2 is fixed in quest/m0/nightly/obs-audio-candidate.md:13–22: the plan now recognizes the shared mutex, requires identifying the failing conjunct and track/error, and chooses a fix only after reproduction. This corrects the plan; it does not claim the underlying flake is fixed.
No new actionable bugs found in this update. Combining the duplicate load/TSan quests is simpler and preserves both validation targets. The other substantive follow-up plans are unchanged after accounting for the base update.
Verification: static comparison with the last published review and relevant OBS source only. No tests, Nightly reruns, builds, or benchmarks run.
Since the last summary: renamed the poll_closed quest to m0/nightly/hls-poll-closed-gate.md. It now also has the gate check each crate's feature shapes in isolation, because workspace feature unification (moq-cli enables moq-hls server) hides the warning from both #6703's gate and Nightly. Codex reviewed c8063ec with no findings, the OpenAI review of ecbfb19 found nothing new, required CI passed, and quest check passes (560 documents). Re-landing through the merge queue.
No new actionable bugs found in the feature-gate plan update. Checking each selected package in a separate invocation addresses the concrete unification hole: moq-cli enables moq-hls/server, while the current feature-shapes recipe combines the selected packages. Gating the server-only poll_closed and measuring the added CI cost is a focused approach.
The prior OBS diagnosis correction remains intact; this change neither fixes nor claims to reproduce that flake.
Verification: static review of the changed quest against the feature-check recipe, selection logic, manifests, and HLS method. No builds, tests, or timing measurements run; this PR still changes plans only.

removed this pull request from the merge queue due to a conflict with the base branch
Oct 25, 2026
The queue dropped this for a conflict: #6708 finished shallow-base.md and turned the nightly epic into a sized leaf. 09edbec keeps the epic unsized with the three children from this PR. Codex reviewed 09edbec with no findings, required CI passed, and quest check passes. Re-landing.
Aligns with the quests #6707, #6790, and #6817 added: net-async-free links the poll-first async feature.
