Finishes quest/m0/app-macos.md.

Problem

Capture had never run in the studio on a Mac. The quest had an agent on the maintainer's Mac exercise camera, display, window, microphone, and system audio through preview, program, the broadcast, and the Devices panel, and fix what only shows up there.

Approach

Two runs on the maintainer's MacBook Air (Apple Silicon): moq-studio --features capture (release) and the pinned moq's moq-relay and moq CLI, a local relay, and scene files holding each source. Each broadcast was recorded with moq export mp4 and checked with ffprobe, a frame pulled with ffmpeg, and volumedetect for loudness. The second run (2026-11-08, main at bfc823b, moq 079a6460f) had the maintainer clicking along in the Devices panel while the agent watched the log and the screen.

Source	Result
Display	Works: ScreenCaptureKit at 1710x1106; the broadcast carries 1280x720 and 640x360 H.264 at 30 fps with the screen's picture
Window	Works: added from the Devices panel (Ghostty, Chrome), drawn in preview and, after Cut, on the broadcast at its place
System audio	Works: Opus 48 kHz stereo, mean -34 dB / max -14 dB while system sounds played
Microphone	Works (first run): Opus 48 kHz, mean -43 dB / max -29 dB room sound. The second run, launched over SSH, got the typed microphone access denied error naming the System Settings pane, as expected without the grant
Camera	Needs moq's fix: AVFoundation delivers 2vuy, which the CPU download refuses (expected NV12). A local patch asking for 420v brought it to program and the broadcast; the fix is moq's quest/m1/camera-nv12-macos.md, in review as moq-dev/moq#8251
Devices panel	Works: lists cameras, displays, windows, and audio inputs, and adds each. The list is a snapshot until Refresh (follow-up below)
Preview, Program, Health	Work: drag, Cut, and each failed source's reason in red in Health and Sources

Along the way, a release build of the studio failed to link on the Mac: two versions of the rind crypto crate, whose assembly fat LTO cannot link twice. #70's branch predates the drift; the fix is its own PR (see Decisions).

This PR deletes the quest and the links to it, which unblocks quest/m0/packaging/macos.md and quest/m0/vcam/macos.md from it (and drops it from quest/m0/browser-source/macos.md). The Mac camera wait now lives in quest/m0/packaging/macos.md, which owns the app bundle since moq-dev/studio#123.

Decisions

Settled with the maintainer on 2026-11-08 (/quest-iterate):

• What quest(m0/app-macos): record what the Mac capture run found and waits on #70 does with the quest: ✅ finish it, since the camera's fix lives in moq's own quest with its test and the patch already proved the path on this Mac (rejected: keep the quest open for the camera, which holds these findings unmerged until moq#8251 and a gitlink bump land).
• Where the release-link fix goes: ✅ its own PR off main (rejected: merge main into quest(m0/app-macos): record what the Mac capture run found and waits on #70 and fold it in).
• Guarding against the drift: ✅ just upgrade-moq moves every crate both lockfiles hold to moq's tested version (rejected: pin only, which the next bump can undo; a CI release build, a long fat-LTO build on every PR).
• Follow-ups: ✅ plan Devices auto-refresh (rejected: a clearer locked-screen error in moq-video, rare; listing windows on other Spaces, which OBS also omits and Refresh covers).

Impact

None for users; quest files only. No public API or wire change.

• CodeRabbit's camera findings: ✅ the macOS app (quest/m0/packaging/macos.md) waits on fix(video): request NV12 from the macOS camera moq#8251 and the gitlink bump under ## Waiting, so no release ships a Mac camera that lists but shows no picture, while the quest itself still finishes as decided above (rejected: a separate pin quest in m0's Required, a second home for the same wait).

Follow-ups

• Studio: refresh the Devices list when its tab is shown. Today a window opened after launch is missing and an added device vanishes until Refresh. Plan via /quest-plan.
• moq-dev/moq: AVFoundation camera asks for NV12, moq-dev/moq#8251, then a moq gitlink bump here.
• moq-dev/moq: keyframes by time, already planned in moq-dev/moq#8249. Displays hit it too: a track's groups are longer than the declared join interval ... interval=2.066s declared=2s.
• moq-dev/moq: system audio's permission failure is a generic capture error, while video's is a typed PermissionDenied. Already planned as moq's quest/m3/audio-system-denied-hint.md.
• Studio: each source that stops logs track::Producer dropped without finish() or abort() for catalog.json and catalog. Drop unless it shows up beyond the log: the tracks end either way.

Validation

• quest check and quest check --base origin/main --branch quest/m0/app-macos: pass.
• just ci: not run; quest files only.
• Merged main after moq-dev/studio#123: packaging.md deleted with its Waiting item moved to packaging/macos.md, browser-source/README.md taken from main, quest check --fix dropped the app-macos.md links; quest check --base origin/main --branch quest/m0/app-macos passes.

No actionable findings in this documentation-only change.

The patch removes the completed macOS capture-validation quest and its references from the milestone, browser-source, packaging and virtual-camera plans. It preserves the remaining signing and Windows prerequisites. The recorded decision to finish this validation quest while keeping the NV12 camera fix and release-link repair separate is consistent with the repository's upstream boundary; this patch does not claim to ship those fixes.

Direction: keep the upstream camera fix and subsequent studio pin update, the release-link repair, and Devices refresh follow-up separate as recorded.

Verification limits: GitHub-only review of all changed documents, base guidance, relevant dependencies, history and the linked camera PR. I did not run quest context, quest check, builds, tests, or any macOS hardware validation. The capture results and local checks reported in the PR were not independently reproduced.

Walkthrough

The milestone documentation no longer lists macOS camera, screen, and audio capture as a requirement. The standalone macOS capture-validation page and links to it were removed.

Merge Risk: Moderate · previous review af64a

Restore explicit prerequisites for pinning and verifying the macOS camera fix before merging. Otherwise packaging and m0 can complete while the tested Mac camera still cannot produce a picture.

Explanation

The title names the quest and the Mac capture run, which is the main change: the PR completes quest/m0/app-macos.md by recording the Mac capture findings and what remains blocked. The title is specific, concise, and matches the objectives and description. It does not describe the rind link fix or the deletion of the quest, but it refers to the real main content.

- Line 29: Add an open packaging prerequisite in the Studio on Windows checklist
for the camera-rendering fix: keep it unresolved until a `moq` version
containing the fix is pinned, rather than treating successful device listing as
sufficient. Preserve the existing checklist structure.

Review comments at @quest/m0/README.md:
- Line 91: Keep macOS camera capture as an m0 requirement by adding a required
pin quest to the m0 quest list that tracks the upstream moq fix and verifies
camera capture after the moq gitlink is bumped; do not let the existing
Windows-host quest replace this requirement.

Incremental review since af64a45d1b2d2180217be72e267f23e7ea6f9fb0.

No actionable findings in the four-line packaging update. quest/m0/packaging.md now explicitly waits for the NV12 fix, the studio gitlink bump, and a Mac camera rendering in program. Since packaging remains Required by m0, this preserves the camera completion gate without reopening the completed capture quest.

Direction: retain this gate until the pin and hardware verification are complete. Upstream moq-dev/moq#8251 has now merged; its merge alone does not satisfy the remaining criteria.

Verification limits: GitHub-only inspection of the incremental comparison, full PR patch, packaging/milestone context, repository guidance, prior reviews, and upstream PR status. No quest context, quest check, builds, tests, or Mac hardware validation were run; reported capture results were not independently reproduced.
