Add the `quest` label to these issues after the PR merges.
Add the `quest` label to these issues once the PR is open, so another planner skips them.

Scope labeling to issues under Closes.

“these issues” refers to the unlabeled input set, which can include issues cited only under Related. Labeling a context-only issue makes later planning skip it. quest/AGENTS.md Lines 82–85 says Related issues get no label. Based on learnings, apply the label only to issues under Closes.

Decided for landing: the line merges to `main`, not `dev`, with a changelog
note for two behavior changes treated as fixes. `@moq/watch` `Sync` takes a
numeric delay literally instead of adding the rendition delay on top

was wrong, and both compile unchanged for existing callers. The line branch is
about 200 commits behind `main` with conflicts in `js/watch/src/sync.ts` and

P2 Badge Update the harness quests to use fresh traces

This new decision says the #3477 traces are gone, but the moved harness plan still says to upstream the released rt-audio-traces-2026-09-06 data, and browser.md explicitly requires trimming those unavailable traces into a fixture. Following the dependency therefore reaches an impossible deliverable; update the harness README and browser quest to record and consume the fresh traces described here. (Written by GPT-5.6 Sol)

ignored; the text handle registers one like audio and video. The MSF

P2 Badge Describe the undeclared-stream fallback in the outcome

Fresh evidence after the earlier jitter review is this parent entry's unconditional outcome: ts-export-jitter.md now explicitly retains a nondeterministic observed-growth fallback for variable-rate or undeclared streams, where the first B-frame at each new maximum can still reorder TS output. Saying a late B-frame “never” reorders output therefore promises more than the child quest delivers and misleads anyone dispatching work from this list; distinguish the deterministic declared-bound path from the acknowledged fallback.

# [XS] The opening-snapshot test waits for real enrollment

## Goal

`archive::tests::an_opening_snapshot_records_every_rendition` in
`rs/moq-cli/src/archive.rs` passes under load. It fails with "writer closed"
because it treats a rendition's `.info` file as proof the export enrolled
that track, then finishes the tracks and the catalog; under load the writer
can still be subscribing when the tracks end. Seen while landing
[#4169](https://github.com/moq-dev/moq/pull/4169).

## Plan

- Wait on the signal enrollment actually produces (the subscription reaching
the publisher, or an explicit event from the exporter), not a file that
appears earlier. No longer timeout and no retry.
- If the exporter can genuinely lose a rendition that ends right after it
appears in the catalog, that is a bug in the exporter, not the test; fix it
there.

Public API: none. Wire: none.

## Quests

- [Named codecs](/quest/m1/audio-codecs/named-codecs.md) - `decode::Kind::Named` keeps the published codec names and picks backends internally; must land before the line merges
- [HE-AAC refusal](/quest/m1/audio-codecs/he-aac-refusal.md) - implicit-SBR HE-AAC over TS is refused instead of half-decoded as the LC core
- [AAC PCE](/quest/m1/audio-codecs/aac-pce.md) - a channel_config of 0 parses the program config element instead of guessing stereo
- [Layout](/quest/m1/audio-codecs/layout.md) - the settled `Layout` carries up to 7.1 through decode, resample, playback, and the FFI

- Regression: a stereo and a 5.1 encode round-trip through the AudioToolbox
decoder and through symphonia (stereo only), with timestamps continuous
across the priming.
- Decided in [#4183](https://github.com/moq-dev/moq/pull/4183): the uniffi
`MoqAudioEncoderOutput::frame_duration_us` default moves from 20000 to 0
(the codec's own frame) with this quest, so `aac()` works without an
explicit 0. Changing a published binding default is a break, so that
change targets `dev`.
