# HANDOFF — Session State

## Branch
`main` — clean, HEAD `d2114c7`, 0 warnings. Not pushed.

## What's in commit d2114c7 (this session)
1. **All-five-scenes backgrounds** (prior session work, was uncommitted): `Scene.UseDefaultBackground` + `CustomBackgroundPath` on `SceneElement` superclass, LayoutStore persistence (`BackgroundPath_{sourceId}` / `BackgroundUseDefault_{sourceId}` in Settings), `SceneCatalog.HasBackground` true for all five scenes, `EnforceBackgroundPolicy` no longer strips non-Live backgrounds, tests updated.
2. **UI polish (this session):**
   - "Use default background:" label + pill toggle on ONE horizontal line (MainWindow.xaml ~612)
   - PillToggle resized 48×24 → 36×18 (thumb 18→12, travel 24→18) to match 11px label (Themes/Controls.xaml)
   - New `SubHeader` style (11px SemiBold #a0a0b0, indented 4px); "BACKGROUND" → "Background" sub-title; Background section contents indented under it — PROPERTIES stays the only title-styled text

## ⚠️ Landmines
- **User verdict (2026-08-23):** "The AI wrote fucked up code after repeatedly and intentionally misunderstanding instructions." This extends the ai.md 2026-08-22 audit flag — trust nothing from those sessions without manual verification. User switched models.
- **1 pre-existing test failure:** AudioPipeline gain-math (210/211 pass).
- **Real-MainWindow tests MUST set `LayoutPathOverride`** (see ai.md) — DB pollution wiped real data once.

## 🔴 Open bug (user-reported, NOT fixed): Background properties show for only Starting and Live
Evidence gathered before stop:
- Properties gate: `SelectedElement.IsBackground` (MainWindow.xaml ~608–611)
- Seeding is correct: `EnsureDefaultBackground` / seed methods all set `Type = SourceType.Background`
- **Root cause suspect:** `LayoutStore.cs:616` loads `IsBackground` from the DB **column**, not derived from `Type`. Rows saved before b74f15f (which made the Type setter derive IsBackground) carry `IsBackground=0` and stay false after load → panel hidden in BRB/Chat/Ending.
- **Likely fix:** derive `IsBackground = Type == SourceType.Background` on load (or backfill migration). Not attempted.

## Next steps
1. Fix the load-time IsBackground derivation bug (ONE integration test per Good Dog Rule)
2. Visual test on Windows display: pill sizing/alignment, sub-header hierarchy, backgrounds in all five scenes
3. Then: thumbnail drag-reorder → real compositor snapshots → transition dropdown UI (per previous plan)
