# HANDOFF — Session State

## Branch
`task25-backgrounds` @ `7dd140a` — **committed and pushed** (includes TASK 24 `b400ab5`). Working tree clean.

## Shipped: TASK 25 background consolidation (+ TASK 24 toasts beneath it)

Locked model (user directive): exactly ONE "Background" per screen at index 0, non-deletable/
non-reorderable, NOT in the (+) menu; capture context-sensitivity only on the Live screen
(Show Desktop/monitor switching kept intact); exactly five default images in the DB; stale rows cleaned.

1. **Seeders consolidated** (`ViewModels/MainViewModel.cs`): five clone seeders + `EnforceBackgroundPolicy`
   deleted. Now: `EnsureBackground` → `CreateBackground(name)` — Live = DisplayCapture row, others =
   static Background art row, all named "Background". `NormalizeBackgrounds(scenes)` heals any layout:
   correct-flavor keep (in-place Type conversion re-asserts `IsBackground` because `Source.Type`'s setter
   derives it), duplicates dropped, missing seeded + INSERTED, index 0, non-canonical stripped.
   `HealBackgrounds()` = Normalize + `StampDefaultBackgroundAsset` (pack-resource art via `AddAsset`;
   custom Browse wins). Called from LoadLayout, StagedScene setter, ReacquireScreenCaptures.
2. **Settings purge:** `LayoutStore.Save` deletes orphaned `BackgroundUseDefault_{id}`/`BackgroundPath_{id}`
   keys (ids gone from Source). Fixes the real DB's 16 stale keys.
3. **UI:** (+) menu Screen+Background items removed (`MainWindow.xaml`); `AddSource` refuses capture/background
   params. `CanChangeBackground` = staged-is-Live → gates preview CanvasGrid menu directly and the layer-row
   menu via new MultiBinding converter `Helpers/AllTrueToVisibilityConverter.cs` (row Tag carries VM bool).
4. **Mini rule:** minis never render captures. `LoadBackgroundImage` is flavor-blind (`IsBackground`) — fixes
   green mini bug (was `Type==Background`, missed Live's DisplayCapture row → placeholder twin at old :951 too);
   `RefreshSnapshotsAsync` shows green placeholder only while Live is staged, otherwise its stored art.
5. **Tests:** suite 221/218 → **223 total, 220 pass**. The ONE integration test:
   `BackgroundHealIntegrationTests.Dirty_Layout_Heals_To_One_Locked_Background_Per_Scene` (seeds dirty temp DB,
   real window, asserts heal + save purges keys). Unit: SceneCatalogTests rewritten (NormalizeBackgrounds heal +
   strip + per-scene flavor), BackgroundTests empty-scene flavor updated, SourceNamingTests filters IsBackground.
   The two stale landmine tests (#2/#3) are healed by this branch — see below.
6. **Docs same commit:** ai.md (TASK 25 model section replaces backdrop-era text), TASKS.md TASK 25 entry,
   Services/index.md (LayoutStore purge), Helpers/index.md (new converter), this file.
7. Build **0 warnings**.

## ⚠️ Landmines

- **User verdict (2026-08-23):** "The AI wrote fucked up code after repeatedly and intentionally misunderstanding instructions." Extends the ai.md 2026-08-22 audit flag — trust nothing from those sessions without manual verification.
- **Pre-existing test failure is now ONE (not caused by these branches):**
  1. `AudioPipelineTests.Mix_HonorsProviderGains_AndGameMute_KillsTheLoopback`
  - Former #2 SourceNaming / #3 SceneCatalog policy tests were repaired BY TASK 25 (expectation updates to the locked model) — not skipped, not deleted.
- **Real-MainWindow tests MUST set `LayoutPathOverride`** (ai.md) — DB pollution wiped real data once.
- **`Source.Type` setter derives `IsBackground`** (Models/Source.cs:40) — any Type change must re-set IsBackground after.
- **vstest quirk:** only one `--tests:` param allowed; plain substrings work (`--tests:BackgroundHeal`), alternation regexes silently match nothing.
- Notification.Wpf gotchas (ai.md/TASKS.md): area routing by XAML `Name`; unknown AreaName silently drops; `NeverExpires()` = `TimeSpan.MaxValue`; `ToHex()` = `#AARRGGBB`.

## Next steps
1. Commit this branch (code + docs, one commit), then merge/PR per Good Dog Rule (one integration test ✓).
2. User visual pass on Windows: minis show art when unstaged (Live included), green placeholder while staged;
   no Game Capture rows in layer lists; (+) menu trimmed; capture controls only on staged Live.
3. Then relaunch app once so the user's real `%APPDATA%` DB self-heals on load + first save purges stale keys.
