chore(quest): plan the ten unlabeled issues - #3539
Conversation
Every open issue without the `quest` label becomes a quest, settles an existing plan quest, or is retired: - #3533 TS export stall: remove the bystander fence #3375 added, after #3529. - #3534 publisher priority survives a moq-transport hop, track-scoped. - #3492 TRACK_STATUS is refused with NOT_SUPPORTED once the error registry lands; a real implementation stays out (#3519 closed). - #3532 the connect race fails on auth only when both arms have; moq-ffi gains the WebSocket toggles. Blind subscribe stays refused. - #2388 an engine-wide WebKit gate now, and a dormant re-enable quest gated on WebKit 319818. - #2815 moq-cli lifts the one-adaptive-stage refusal the allocator obsoleted. - #2933 route cold cost: MoqRoute gains `cold`, defaulting to warm. - #2857 binding rate control: the bindings mirror Allocator and Reservation; OBS adoption is its own quest under obs-moq-video. - #3058 revalidation: tier applies in place, an alias change closes with its own reason. - #3452 is retired without a quest: transcoding is invisible to OBS.

There was a problem hiding this comment.
Deleting the epoch test in Track::admit admits the exact stale bystander guarded by rewind_flags_the_break_once_across_tracks: after audio rewinds to zero, that test queues video at 8–9 seconds and asserts that all output remains below 2 seconds and contains no video PID (export_test.rs:2264-2308). Under this plan, the queued old-generation video instead advances the reset clock, so true multi-track rewinds regress and the promised existing test cannot keep passing. Fix or distinguish the false rewind at its detection/import boundary rather than removing the stale-track protection.

There was a problem hiding this comment.
Properties::encode emits no Track Properties for Draft14–16, and Draft14/15 do not have the trailing property block in SUBSCRIBE_OK at all. Consequently, a DEFAULT_PUBLISHER_PRIORITY property cannot round-trip "per version" as required here; writing 0x21 into those older layouts would instead be interpreted under their message-specific format or rejected. Scope this property behavior to the drafts that register and carry it, while defining the older drafts' priority solely through their explicit group-header/default behavior.

For two ordinary capture stages, each audio encoder currently registers its configured rate but ignores a smaller grant, as the related #2848 quest explicitly documents. When the connection estimate drops below the combined audio ceilings, deleting this guard therefore accepts a configuration whose actual encoder targets exceed the estimate, even though the allocator's grants sum correctly. Make #2848 a prerequisite or retain a narrowed refusal until fixed-rate audio reservations fit within the estimate.

Keeping the refusal lifted. The allocator is advisory by design (#2854: a track that ignores its share still sends what it sends and the transport sheds the excess), and audio holding its configured rate below a smaller grant is the same on one capture stage as on two, so the guard never protected against it. #2848 is the fix for audio and the quest now says so rather than requiring it.

There was a problem hiding this comment.
Connection::run passes an immutable stats::Session into the request before acceptance and then only awaits session.closed() or Auth::expired(); successful Recheck::Valid results are consumed inside the revalidation loop and never reach the connection. Moreover, the origins, scopes, and meters already hold clones derived from the original session, so rebuilding a local handle would not retag subsequent bytes. The plan needs a revalidation event/handle plus dynamically retaggable accounting, or an equivalent data path, before the connection can perform the claimed swap.

The TS export fix keeps the peer fence and gives it a clock-driven exit, so the #3375 true-rewind test keeps passing. The publisher-priority property is scoped to the drafts that carry a property block. The rate-control quest defines the allocator's lifecycle across reconnects and keeps None distinct from a zero grant. The revalidation quest names the data path a tier retag needs and grows to [M].

Normalize explicit subgroup priority to the track value.
The goal says priority is track-scoped, and a subgroup value that differs from track::Info::priority must collapse to the track value. The plan only covers publisher stamping and the absent-flag fallback. GroupHeader::decode currently preserves an explicit wire priority and has no track metadata. Define subscriber-side normalization after track properties are decoded, and add a test for an explicit conflicting subgroup priority.

When the WebSocket endpoint returns the unconditional 403 described above and QUIC fails transiently, reporting an auth error because either arm produced one makes Reconnect::run exit immediately on err.is_auth(). The client then never retries QUIC even though that transport did not reject its credentials, and the proposed “QUIC failure after a WebSocket 403 reports Forbidden” test locks in this failure mode. Preserve a retryable aggregate unless both transports reject authentication, or distinguish the fallback's unsupported-route 403 at its source.

There was a problem hiding this comment.
For the built-in video and audio encoders, the track demand is obtainable only from the MoqVideoProducer or MoqAudioProducer returned by the publish call, but this plan requires MoqBandwidth::reserve(track, max_bps) before passing that reservation into the same publish call's options. No caller can construct that sequence, so the new surface would work for a pre-existing raw track but not for the built-in encoders promised by the goal. Bind a reservation after producer creation or let the publish operation create and return it.

There was a problem hiding this comment.
If this quest starts before #2848, moq_audio::encode::Options has no bandwidth consumer and the audio encoder explicitly reserves but ignores its grant, so passing a reservation through unchanged cannot make the built-in audio encoder follow congestion as the goal requires. A Related entry does not block execution, and this quest has no Required section, so make #2848 a prerequisite or remove audio adaptation from this quest's promised outcome. quest/CLAUDE.mdL75-L82
Useful? React with 👍 / 👎.
An auth error ends the connect race only when both arms rejected authentication, so a fallback 403 cannot stop QUIC retries. The rate-control publish calls take the bandwidth handle and reserve themselves, since a reservation needs the track the call creates; audio holds its rate until #2848. The revalidation re-check compares the alias explicitly and swaps the live tier in shared state as a no-op when unchanged. The subgroup header priority never overrides the track's, and the fence exit is defined against the watermark. Co-Authored-By: Claude Fable 5.1 <noreply@anthropic.com>

When one origin is published through sessions A and B, or a caller simply pairs B's track with A's MoqBandwidth, the proposed API has no relationship between the allocator and the connection carrying that track. The built-in encoder will therefore follow A's estimate even while its bytes are sent through B, and a single shared encoder cannot follow both sessions as promised. Define the multi-session aggregation/ownership policy or bind reservation construction to the actual sending session instead of accepting an arbitrary handle/track pair.

When the alias changes, adding Expired::Alias only distinguishes the relay's internal result and log: Connection::run still maps every result from auth.expired() to session.abort(moq_net::Error::Unauthorized) in rs/moq-relay/src/connection.rs, so the peer receives the same code as an ordinary revocation. The planned internal Expired::Alias test will not catch that the Goal's client-visible distinction is absent; add a distinct close code plus client-facing decoding/tests and the required wire/draft synchronization.

Summary
Grooming pass over every open issue without the
questlabel (/plan-issues). Each one now either has a quest, settles a plan quest that was waiting on this session, or is retired with a reason. Quest-tree only; no code, no wire or API impact.New quests
moq export ts: a continuous timeline whose content restarts permanently stalls video and primary audio since #3375 #3533 TS restart stall [S]: the peer fence fix(moq-mux): recover buffered TS output after a rewind #3375 added leaves bystander tracks in the old generation with no way back once a sub-frame audio resync is read as a rewind. The fence stays (it is what the fix(moq-mux): recover buffered TS output after a rewind #3375 true-rewind test asserts) and gets a clock-driven exit: a fenced track re-joins when the program clock passes its pending frame, so a false rewind costs one frame instead of a permanent stall. A regression arm covers a continuous transport timeline whose content restarts. Required after fix(mux): preserve a signalled MPEG-TS timebase discontinuity #3529, which edits the same functions. The inferred rewind itself is retired by the existing monotonic-timeline quest.track::Info::priority, absent flag resolves to the declared default. Track-scoped, as moq-lite already defines it. js/net mirrored.set_websocket_enabled/set_websocket_delay(libmoq already has them). Blind subscribe stays refused, stated in the Goal.Closes.Plan quests settled into implementing quests

A bare "follow the estimate" flag was ruled out becauseMoqBroadcastProducerhas no session.
