Problem

A /quest-audit of moq-dev/studio found its quests waiting on moq quests that
sat in the deferred milestone, described a layer layout missing two of the
studio's four strip settings, and relied on two moq changes that had no quest.
The maintainer settled each in a /quest-plan interview on 2026-11-09. This
PR applies those decisions to moq's quest tree. It edits only quest/.

Approach

Each decision, with its reason:

1. Three quests move from m5 to m3, with quest mv:
   quest/m3/audio-encode-audiotoolbox.md,
   quest/m3/audio-encode-mediafoundation.md, and
   quest/m3/audio-filters.md. The studio's m0 quests wait on them through
   its pin quests (quest/m0/pin-aac-encode.md and
   quest/m0/pin-audio-filters.md in moq-dev/studio), and m3 is where work a
   named consumer waits on belongs. Each Plan records it, and the m3 and m5
   READMEs' lists follow.
2. An audio layer carries pan and delay as well as gain and mute
   (quest/m3/layers/spec.md). The studio's strip has all four
   (rs/moq-scene/src/collection.rs there; pan shipped in
   moq-dev/studio#116), and a
   source's own track is taken before them, so a delayed microphone published
   on its own track would play out of sync for viewers without it.
3. moq play toggles layers and maps their priorities
   (quest/m3/layers/play.md): a viewer switches off any layer the layout
   marks toggleable, which unsubscribes its track, and each layer's priority
   maps onto moq-lite's subscription priorities. The studio decided on
   2026-11-08 (its quest/m2/compose/controls.md) that viewer controls land
   in the native player, and its prototype player is deleted once hang
   specifies layers, so this quest is their home.
4. New quest quest/m3/rtmp-rtmps-tcurl.md (S): moq-rtmp dials
   rtmps:// itself and advertises a URL-derived tcUrl. Today the only TLS
   route, Client::with_stream, passes tc_url: None
   (rs/moq-rtmp/src/dial.rs:107), and several ingest servers reject a
   connect without one. Consumer: the studio's quest/m0/destinations.md.
5. New quest quest/m3/webrtc-dial-policy.md (M): moq-webrtc's WHIP and
   WHEP client dials through a caller-supplied policy, so a server-side host
   can refuse private and loopback addresses. Today moq_webrtc::Client
   builds its own reqwest::Client and dials whatever URL it is handed
   (rs/moq-webrtc/src/client/mod.rs:48). Consumer: the same studio quest,
   whose egress library a hosted service reuses.
6. The browser quests stay deferred (quest/m5/video-web.md,
   quest/m5/audio-web.md). video-web.md asked whether the web studio
   still wants it: the maintainer moved the studio's web build to the
   studio's m2, so both stay in m5. Their links follow the studio quests from
   quest/m0/ to quest/m2/ there (web.md, pin-browser-video.md,
   pin-browser-audio.md).

Choices this PR made beyond those decisions, for review:

• quest/m3/audio-decode-mediafoundation.md moved too. The Media
  Foundation encoder requires it for its round-trip regression, and the m3
  README says a quest joins m3 "when an m0 to m3 quest requires it". No quest
  in m0 to m3 otherwise requires an m5 quest. The alternative is to leave it
  in m5 and let an m3 quest wait on a deferred one.
• The players mix at all four settings. layers/README.md, play.md,
  and watch.md said "gain and mute"; they now say gain, mute, pan, and
  delay, since a layout field no player applies would not fix the sync
  problem. watch.md changes in that phrase only.
• play.md carries the studio's per-track rule: a track several layers
  show stays subscribed while any of them is on, at the highest priority
  among them. It is from the studio's controls.md, which goes away with its
  prototype.
• The RTMP quest's tcUrl comes from the URL as written, on both
  schemes. The studio's quest describes plaintext Client::connect as
  already URL-derived. It takes a resolved SocketAddr and advertises
  rtmp://<ip:port>/<app> (rs/moq-rtmp/src/dial.rs:90), which loses the
  host name. So the quest has the client dial a URL for both schemes. It also
  includes rtmps:// in the moq CLI, which refuses every scheme but rtmp
  today and has to change with the entry point anyway.
• The dial-policy quest covers more than the WHIP POST: HTTP redirects,
  which reqwest follows by default; the answer's remote ICE candidates, which
  the session sends UDP to (rs/moq-webrtc/src/ice/agent.rs:314); a host
  name checked on the address actually dialed; and WHEP, which shares the
  client.
• moq-rtmp has the same gap only after quest 4. It never resolves a name
  today, since the caller hands it a SocketAddr or a finished stream. Once
  it dials a URL it does, so the dial-policy quest covers moq-rtmp and
  requires the RTMP quest. moq-srt also takes a SocketAddr and is not a
  studio destination, so it is left out.

Merge with main

moq-dev/moq#8423 pruned m5 after checking only moq.pro for consumers, deleting the four audio quests this PR moves. The merge keeps them in m3, since moq-dev/studio consumes them, and drops their Related links to pruned m5 quests (MediaCodec encode and decode, OBS Windows decode).

Impact

None. No code, public API, or wire change.

Alternatives

• Folding the dial policy into the RTMP quest: rejected, since the policy
  spans two crates and the RTMPS dial is useful to the CLI without it.

Follow-ups

• moq-dev/studio: its pin quests (quest/m0/pin-aac-encode.md, pin-audio-filters.md, audio-filters.md) link to the m5 paths; switch them to m3 once this merges.

Validation

• quest check: 578 documents ok.
• just ci: passed (biome, markdown, gh, quest, shell, large_files, text, toml,
  nix, and justfile checks, and the gh tests, which is what a quest-only diff
  selects).

No actionable findings in this planning-only change. Moving the Windows decoder with its encoder preserves the stated test prerequisite. The layer plans carry pan/delay into both players, and the native player's per-track subscription rule matches the studio plan. The RTMP and WebRTC source confirms the tcUrl and dial-policy gaps described here; including redirects, resolved addresses, and remote ICE destinations avoids limiting the policy to the initial HTTP URL.

Direction: retain the separation between URL/TLS dialing and the shared host policy. The new studio m2 browser links depend on companion moq-dev/studio#123, where those moves are present but not yet merged; the repository-local links all resolve.

Verification limits: GitHub-only inspection of the changed plans, relevant source, and companion plans. No quest validation, tests, or TLS/ICE integration runs were executed. GitHub Check was still running when inspected.

Reviewed changes

• Four quests move from m5 to m3 (audio-encode-audiotoolbox, audio-encode-mediafoundation, audio-filters, and audio-decode-mediafoundation), each with a dated Plan entry, retargeted cross-quest links, and both milestone README lists updated.
• Audio layers carry pan and delay in layers/spec.md, layers/README.md, layers/play.md, and layers/watch.md, matching the studio strip's four settings.
• moq play gains the viewer toggle and the per-track priority rule in layers/play.md.
• Two new m3 quests: rtmp-rtmps-tcurl.md [S] for a URL-dialing RTMP/RTMPS client with a URL-derived tcUrl, and webrtc-dial-policy.md [M] for a caller-supplied address policy across WHIP, WHEP, redirects, ICE candidates, and RTMP.
• Browser quests stay deferred in m5, with their studio links following the companion move to studio m2.

I checked every code citation against this base (dial.rs, moq-cli/src/rtmp.rs, server.rs's tc_url/tls_fixture, moq-webrtc/src/client/mod.rs, ice/agent.rs), and they hold. No /quest/m5/... reference to a moved slug remains, every root-absolute link in the changed files resolves, and the 578-doc count matches the tree. The new studio m2 links currently 404 on studio main but resolve in the open companion moq-dev/studio#123, which also retargets its pins at the new m3 paths and adds the egress-dial pin for these two quests — so the paired PRs just need to land together.

Walkthrough

The pull request updates quest documentation across m3 and m5. It moves audio codec and filter-chain entries to m3, expands the layer playback goals and plans, and adds documentation for RTMP/RTMPS URL dialing and caller-supplied dial policy. It also updates browser audio and video links and plans. These changes document goals, dependencies, decisions, and test expectations; they do not implement the described features.

Merge Risk: Low · up to 793c1

This is a documentation-only change with no code, API, or wire effects. Cross-repository links in the studio docs will point to removed paths unless studio updates them, so coordinate that before or right after merging.

✅ No new issues found.

Reviewed changes

• Merged origin/main's quest pruning (cd560bde5, #8423) into the branch, keeping the four moved audio quests at m3 rather than restoring their deleted m5 copies.
• Dropped the pruned Related links from the moved quests: MediaCodec decode in audio-decode-audiotoolbox, MediaCodec encode in audio-encode-audiotoolbox, and OBS Windows decode in audio-decode-mediafoundation.
• Let the m5/README.md edit go: main's rewritten README already omits the moved quests, so the PR no longer needs to change it.
• Re-checked the merged tree: every root-absolute link in the 16 changed files resolves, no /quest/m5/... reference to a moved slug survives, and each moved quest appears once in quest/m3/README.md.

No rs/ or doc/ changes landed between the two bases, so the new quests' code citations still hold at cd560bde5. CI Check passed on 5837b64.
