# HANDOFF — 2026-09-10 (transparency hardening applied)

## Branch / Commit State

`main` HEAD will be = the new transparency-hardening commit (slice 14). Ahead of
origin by 19, NOT pushing (user ruling: no push until web-overlay transparency AND
audio-silence are addressed).

## ACTIVE THREAD (ONE problem at a time)

**Web-uri transparency — second hardening applied (background-image wipe), awaiting take.**
The 15:34 take: the recording's box interior is the widget's OWN full-canvas opaque paint
(bright content strips at top/bottom + right bar over a black void) — NOT desktop, NOT a
compositor blend. The real-document dumps showed blank-transparent at +1s and the page's
backdrop appears later; a background-COLOR-only `!important` wipe (b4bba4b) leaves CSS
background-IMAGE (gradient/backdrop) intact — the OBS answer is `background: none
!important`, background-image too (obsproject/obs-studio#6659).

**Slice 15 (commit target, the fix):**
- `TransparentBackgroundScript` now also wipes `background-image:none!important` on
  `html,body,html *` (gradients/backdrops die; `<img>`/DOM art survives — OBS semantics).
- `NavigateCompleted` re-arms `WidgetDumpRemaining = 5` ~30s in, so this take dumps the
  real document INSIDE the recording window (the missing evidence last time).
- Test extended (asserts `background-image:none!important` present, weak inline form absent).

## THE ONE REMAINING STEP (verify, no further analysis)

1. User records the Live scene, widget animating (pre-record ~35s so the 30s re-arm dump
   fires mid-take).
2. Verdict: element rect shows the scene backdrop behind the widget art (no black box/void)
   → transparency CLOSED, push gate #1 clears. If a black void persists BEYOND a visible
   background-image, it's not background painting and only chroma-key remains — bring the
   take and we do the compositor key, not more capture investigation.
3. Then the queued layer-order-save bug (reorder doesn't persist `SortOrder`) is next.

## Other threads (paused)

- **Audio silence** — `f3d578c` has per-5s `Audio live:` telemetry; next take with desktop
  audio ACTIVE names the stage. Push gate #2.
- **Webcam missing** — "MJPG negotiation refused (being used by another process)". Queued.
- **Web capture speed** — ~10-14Hz effective, user satisfied. Revisit only on request.

## Landmines

- testhost shares startup.log with the app — filter by time.
- App was running at commit time; `taskkill //F //IM ytLive.exe` (Windows `taskkill.exe`,
  bash-quoted `//F //IM`) before rebuilds, and re-run if `MSB3021` copy-lock appears.
- Build/tests: `/mnt/c/Program Files/dotnet/dotnet.exe build …` / vstest.
- Probing: `/mnt/c/Program Files/Krita (x64)/bin/ffmpeg.exe` / `ffprobe.exe` — Windows exes
  take Windows-style paths.
- Never re-derive the transparency story again — MyMistakes "SPIN GUARD → RESOLVED" is the
  record (wash-rinse-repeat cost the user a whole session).
