The creator couldn't add a webcam to Live (grayed app-wide) and nothing in the app explained why. Ground truth from the live DB: one Webcam identity AND one WebcamSceneConfig in the Chat scene — so the gray was the single-identity rule working, but the reason was unobservable. This slice makes the webcam a resource the app validates and locks, mirroring how OBS reserves its devices. At startup we enumerate the OS once (ValidateWebcamResourceStartupAsync, fired after LoadLayout, stored as WebcamStartupValidationTask for tests to await): - 0 webcams -> app runs on, layer inactive, no alarm - exactly 1 -> attempt CameraManager.AcquireAsync as an app-wide lock; on failure show a persistent red alert at the bottom of the Layers panel (WebcamLockAlert + Retry) that re-polls every 5s and clears itself the moment the camera locks, or on any first real frame - >=2 -> deliberately no auto-lock; camera selection belongs to the App Settings dialog (gear) — next slice CameraManager.IsRunning(deviceId) tells the pass a session already exists (started OR still starting) so loaded identity configs count as the lock and the pass never double-acquires. Test seams mirror LayoutPathOverride: CameraEnumeratorOverride / CameraFrameSourceFactoryOverride so the startup probe never touches real hardware under test. Good Dog test: WebcamStartupResourceTests x3 — single-cam locked + app runs on, zero-cams no-alarm/no-lock, lock-fails -> red alert -> Retry -> clears. Full suite 304/304, build 0 warnings, scope-check passed. Docs in-commit: TASKS Open items + ai.md Webcam section + HANDOFF rewrite. Also corrects the record: 'NVIDIA Broadcast opens the webcam exclusively' was a suspect-list claim (CameraConflictProbe reads process names only, no handles) — not restated as fact.

ytLlive — Task List
Catalog: task files live in
TASKS/(one file per task). This file is the index. Memory-map conventions:schema.md; architecture/decisions:ai.md.
Checklist markers — every task's Status line uses the same states:
- ✅ — completed / shipped
- 🔶 — in progress
- ⏳ — blocked / waiting
- ☐ — not started / queued
- ❌ — exception (known-issue, deliberately excluded, or merged)
2026-09-01 — v1 = feature-complete ruling: there is no v1.x. Everything queues to v1 or to "Out of product — permanently" (file end). Read those two sections before adding or reviving anything here.

Out of product — permanently
These were explicitly ruled out:
- D3D11 swap compositor (superseded by software compositor; TASK 3 item 16)
- Background removal (ONNX/DirectML; TASK 3 item 19)
- OBS-style source expansion (game capture, browser source, media playlist, VLC, color-key, MIDI — the minimal source set is deliberate; creators who need more have graduated to OBS)
- Multi-layout (auto-save, single layout; multi-layout = OBS territory)
- Cross-process stream resume (API makes it impossible; creator ruling 2026-09-01)
