Summary

Plans the follow-ups raised on #3, #4, #5, #6, #8, #9, and #10. All join m0, the studio's only milestone.

New quests:

• [S] Outside edits to the scene file (outside-edits.md)
• [XS] Worker threads fail loud at startup (thread-start.md)
• [S] Health grades source tracks (health-sources.md)
• [S] Audio sources report stalls (audio-stall.md), which waits on pin-audio-capture.md from feat(scene): publish each picture source as its own track #3
• [S] Browser sources keep a profile (browser-profile.md)
• [S] Browser source popups (browser-popups.md)
• [M] Guest return feed (guest-return.md), which waits on mixes
• [M] Guest token refresh (guest-refresh.md)
• [XS] moq-video's program readback is pinned (pin-readback.md), which now blocks vcam/linux.md
• [XS] The program encoder drains (program-drain.md), from #3

Edits:

• compose/layout.md: clones and filters travel in the layout. The Required on source tracks becomes Related, so layout can start on the picture tracks.
• scene-editing.md: adds undoable transition settings to the Goal.
• vcam/linux.md: the Devices panel leaves out the studio's own camera, and the quest waits on the readback pin.
• The macOS --features capture build failure moved to #13, which splits app.md.

#3 has landed, and its layout note on clones and filters is merged with this one.

Decisions (2026-11-02, maintainer, /quest-plan)

• Which studio quests to plan:
  • ✅ Outside edits
  • ✅ Threads fail loud
  • ✅ Health grades sources
  • ✅ Audio stall detection
• Browser follow-ups:
  • ✅ Shared profile + refresh
  • ✅ Draw popups
  • Program-clock frames (dropped: no consumer yet)
• Guest follow-ups:
  • ✅ Return feed
  • ✅ Token refresh
  • Guest names + waiting room (dropped)
  • Hosted issuer waiting quest (dropped: no API to build against)
• Fold-ins:
  • ✅ Encode burst into feat(studio): guided setup on first launch #7, which feat(studio): guided setup on first launch #7's /quest-iterate is implementing
  • ✅ Layout plan notes
  • ✅ Transition UI into scene-editing
  • ✅ Hide own vcam in vcam/linux
• Program encoder drain (from feat(scene): publish each picture source as its own track #3):
  • ✅ An [XS] quest here
  • Fold into encode-control
  • Drop
• Guest return feed audio:
  • ✅ Wait for mix-minus
  • Program video now
  • Program audio now
• Settled earlier the same day: one shared CEF profile; autosave reloads silently when nothing is unsaved and otherwise pauses and asks keep-mine or take-theirs; clones and filters travel in the layout track; the readback goes upstream first.
• moq-side quests (the readback Exporter, a track's bandwidth grant, test_relay stats, epoch following): ✅ none yet. The maintainer asked to hold them, so pin-readback.md names the upstream change itself.
• Dropped as already covered: @moq/watch .echo feedback, since moq main has js/watch/src/echo.ts.

Review

Codex (quest review), gpt-6.1-sol, medium effort, against origin/main (7ce05db).

• Round 1 on 7a7b550: no findings.
• Online reviewers on 7a7b550, all fixed in 27d092c:
  • OpenAI P2 and CodeRabbit (layout.md): the layout and source-track plans disagreed on audio filters. Video filters travel in the layout; audio tracks publish after their filters, so the layout carries only gain and mute for audio.
  • CodeRabbit (guest-refresh.md): the plan now says the studio signs renewals and delivers them over the room before exp.
  • CodeRabbit (thread-start.md): the plan now covers a failed source thread spawn, shown as that source's failure.
• Round 2 on 27d092c, with those responses: no findings.
• CodeRabbit (review body, outside-edits.md): the conflict check and the rename were separate steps. Fixed in ab88dd2: check again right before the rename, and close or document the remaining window.
• Round 3 on ab88dd2: no findings.
• OpenAI (review body, outside-edits.md): no lock binds an arbitrary editor, so the guarantee was unenforceable. Fixed in 0b57207: the Goal states a best-effort contract with the check-to-rename window named in README.md.
• Round 4 on 0b57207e8fc92087c8bfae704eacf523607e703f: no findings.

Reviewed commit: 7a7b550

P2 — Align the audio filter contract (quest/m0/compose/layout.md:25–30). The layout plan says every source track is captured before filters and carries source filters for the viewer to apply, while quest/m0/compose/sources.md says audio tracks are published after source filters. Applying the layout filters again would double-process audio; skipping them contradicts this contract. Specify which tracks are prefiltered or change the source-track plan, and test program/viewer parity.

The follow-up split and linked dependencies are otherwise coherent. Verification: static GitHub inspection only; no tests run.

Walkthrough

The M0 quest index now links to requirements for worker startup, encoder draining, external scene-file edits, source health and audio stalls, guest features, browser sources, and Linux virtual-camera readback. New quest documents describe these goals and plans. The composition-layout document now distinguishes video and audio filter handling. The scene-editing goal now includes transition-setting edits as undoable steps.

Merge Risk: Minimal · previous review 0b572

The documentation changes have no established merge-blocking issue. Guest renewal follows the documented studio-held signing-key model; hosted issuer support is not a requirement of this quest.

Full details: Title check

Explanation

The title "quest: plan follow-ups of the 2026-11-02 quest-complete merges" matches the main change. The PR adds and edits planning documents under quest/m0 for follow-ups raised on earlier PRs (#3 through #10), including outside edits, thread startup, source health, browser profiles and popups, guest return and token refresh, readback pinning, and encoder draining. The title is specific and concise, and it names the core change, which is planning the follow-up quests.

Full details: Description check

Explanation

The description states the purpose of the PR: planning follow-ups raised on PRs #3, #4, #5, #6, #8, #9, and #10. It lists the new quests and the edits to compose/layout.md, scene-editing.md, and vcam/linux.md, all of which match the raw summary. It also records maintainer decisions and review rounds for the outside-edits and layout documents, so it is directly related to the changeset.

Specify a conflict check that covers the rename.

18-19: 🗄️ Data Integrity & Integration | 🟡 Minor | 🏗️ Heavy lift

Specify a conflict check that covers the rename.

The plan detects outside edits by comparing the file with the last value read or written. That check and the rename in write are separate steps. write performs no content comparison before persist, and it does not lock the file. Another studio can write during the fsync interval. The plan should require a final comparison immediately before the rename, and it should state how a cross-studio lock or a residual race is handled.

Reviewed commit: 27d092c

The earlier audio-filter contradiction is fixed: audio tracks are post-filter and the layout no longer asks viewers to apply those filters again. The thread-startup and guest-renewal plans also clarify prior independent findings. No new actionable issue found in the update. CodeRabbit's outside-edit race remains separately tracked at #12 (review).

Reviewed commit: ab88dd2

The update adds a final comparison and documents the residual race, but the outside-edit guarantee remains unresolved as already reported in #12 (review). Advisory locks coordinate cooperating Studio instances, not arbitrary editors, and a check/rename window remains. Either specify an enforceable cross-writer guarantee or state a best-effort contract rather than promising that external edits are never silently overwritten.

Verification: static GitHub review only; no tests run.

Addressed in 0b57207: the Goal now states a best-effort contract with the check-to-rename window named in README, and the Plan says no lock binds an arbitrary editor.

Reviewed commit: 0b57207

No new actionable issue found. The previous outside-edit finding is addressed: the goal now names the residual check-to-rename race and requires documenting it, rather than promising protection against uncooperative writers. The final comparison remains required.
