Slice 5a, scaffolding only. 607 green.
- `Source.IsReplayLayer` + schema column + roundtrip: a media layer that shows saved clips instead of a
chosen file. The compositor needs to know nothing — it is a media layer whose path the VM owns.
- **Two spec corrections from the creator (2026-11-10), recorded in the task:**
1. The immediate replay of a fresh clip happens **only in the Live scene**. While it plays, **F10 is
inert** ("replay in progress").
2. That guard replaces the "layer excluded from its own clip" idea, which is **impossible** with one
encoder and two muxes: the clip is a second mux of the same frames, so it necessarily contains what
viewers saw. No second encode, no fiction about a clean feed.
Remaining for 65: the add-layer menu entry, `ClipSaved` → play (Live: once then hide; elsewhere: loop the
kept set), `SessionCompleted` → advance or hide, and silent-by-default audio.
Creator ruling 2026-11-09: finish the queue before the new features, gold pass always last.
**Retired (platform's surface, not ours):**
- 34 scheduled streams — YouTube owns scheduling *and* the reminder that makes it worth anything.
- 50 publish recording — Studio owns upload (resumable, quota-aware, explains rejections), and an
in-app uploader would widen the OAuth consent to whole-channel video management for one convenience.
The app adds "Show in folder" instead.
**New tasks:** 65 replay clips (the creator-side buffer YouTube does not give you), 66 timed ticker
messages, 67 per-event alert videos, 68 edit-while-live + first-run On-Air.
**TASK 65 spec** is the interesting one: 15 s is a clip (10/15/20, default 15); the ring holds encrypted
*encoded* fragments in RAM — raw 1080p frames would be ~7.4 GB for 15 s — so there is no steady disk
write and no crash debris; F10 saves; the replay layer plays once then hides in Live and loops the last
1–3 elsewhere; silent by default; three kept; the layer is excluded from its own clip (hall of mirrors).
**TASK 14 gains Branch 3:** mic input gain ahead of the gate (table boom mics fall under it), webcam
blank hotkey, opacity/geometry parity with a collapsed Geometry disclosure, Show-in-folder.
**Decisions recorded:** the replay-buffer reversal (it was retired in 2022-era reasoning as "different
product"; the case for it won), the platform-surface rule, and voice triggering deferred — always-
listening in a streaming app hears the game, so the content is its own false-positive source.
Queue refactored to 56 lines by archiving completed rows and the superseded surge plan; HANDOFF at 40.
