# HANDOFF — 2026-11-05 (alert stack + media/chroma fixes)

## State

- `main`. TASK 21 (video layer + soundtrack), TASK 64 (green/blue screen) and TASK 32·4 (fragmented MP4)
  are complete; TASK 49 is retired (YouTube owns chat moderation — we just don't paint tombstones).
- **Left panel alert stack** shipped: Steam licence indicator pinned at row 1 (`Entitlement 30 fps ·
  Maximum 60 fps`, pin → close once owned, permanent while owned), event rows LIFO beneath, click →
  About or the Logs tab with that event's lines painted. Detail: `docs/ai/ui-surface.md`.
- Video layer fixes this session: the preview-pane trigger whitelist (a video layer was invisible), a
  quadratic frame copy that capped 1080p playback at 2 fps, and deadline pacing for video *and* audio.
- Tests: 575 green, 1m50s; `FAST=1 ./scripts/verify.sh` = 527 in ~62s.

## Next action

- **32·1 + 32·2 shipped**: blip retry (immediate/+1/+2/+3 s), and the RECONNECTING sign driven by the
  status poll (4 s cadence while recovering) with **measured** elapsed/attempt only — the countdown was
  dropped after the creator pointed out YouTube's cutoff depends on variables we cannot see. The
  `chatEndedEvent` in the chat feed now prompts an immediate status check.
- **32·5 shipped**: ingest pre-flight (TCP, 2 s) aborts go-live before any API call, so a dead
  network leaves no ghost broadcast.
- Next:
  then 32·2/32·3 (countdown + Back on air) which need YOUR measurement take: pull the network on a
  private stream and time how long YouTube holds the broadcast.
- Open loop: `32·4` is proven by construction only — kill ffmpeg mid-recording and play the file.
- Do not push absent a checkpoint request.

- **Steam is a wait, not a task:** partner account exists, identity verification pending, tax review in
  Valve's queue (up to 30 business days). No app IDs, no store page, Release entitlement still fails
  closed. Earliest realistic launch early-to-mid February 2027 — see `Distribution.md` §2.

## Landmines

- **The preview pane draws frame-source layers from a whitelist of DataTriggers.** A layer type with no
  trigger is invisible in the preview while its decode looks healthy (alert box 2026-09-26, scoreboard,
  video layer 2026-11-05). Add the trigger with the layer type; pin it with `MediaPreviewDisplayTests`.
- Nothing in the suite drives the real cursor any more; the drag arithmetic is pure (`DragReorderMathTests`).
- Integration tests constructing `MainWindow` must set a temporary `LayoutPathOverride` and clear it in `finally`.
- Media sessions are keyed by **path + look** (`MainViewModel.MediaSessionKey`); never acquire by raw path.
- Bundled FFmpeg stays outside the single-file exe (`ExcludeFromSingleFile="true"`).
