# HANDOFF — Session State

## Branch
`main` — clean at `4b9a8e5` (Control Surface UX: pill toggle, background rename, per-scene properties).

## What shipped this session

1. **TASK 10 — Polar billing + Velopack auto-updates (steps 1–7)**
2. **TRAX meter double-attenuation fix**
3. **LAN infrastructure documented** — all servers in `ai.md` + `CREDENTIALS.md`
4. **llamavault NFS/SMB diagnosis**
5. **Control Surface UX** — all 10 phases complete (StagedScene/LiveScene, thumbnails, edit gating, transitions, brand rename)
6. **Sliding pill toggle** — green ON (#22c55e) / red OFF (#ef4444), replaces checkbox
7. **Backdrop → Background** — full C# rename, SQL column rename with migration, asset files renamed, `Source.IsBackground` `new` → `override` fix, legacy "Backdrop" display name migration
8. **Geometry mismatch error** — red text when custom background aspect ratio >5% off 16:9
9. **Per-scene background properties** — pill toggle + custom path persist per-scene via Settings table

## Background properties (fully shipped)
- `Scene.UseDefaultBackground` (bool, default true) + `Scene.CustomBackgroundPath` (string?)
- Persisted as `BackgroundUseDefault_{sceneId}` / `BackgroundPath_{sceneId}` in Settings table
- Pill toggle ON → loads default asset from DB; OFF → loads custom file path
- Custom path preserved when toggled back ON (not cleared)
- Geometry mismatch: aspect ratio check ±5% of 16:9, shows expected 1920×1080

## Next steps
1. **Visual testing** — run on Windows display, verify pill toggle, background properties per-scene
2. **Thumbnail drag-reorder** — reorder scenes via drag on thumbnail strip
3. **Real snapshot generation** — replace placeholder colors with compositor-rendered thumbnails
4. **Transition dropdown UI** — add XAML control to pick transition type + duration
