HANDOFF — Session State

Branch

task25-backgrounds (from task24-notifications @ b400ab5, committed) — dirty, uncommitted, TASK 25 complete and green.

Uncommitted work: TASK 25 background consolidation — COMPLETE, ready to commit

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.

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.
Settings purge: LayoutStore.Save deletes orphaned BackgroundUseDefault_{id}/BackgroundPath_{id} keys (ids gone from Source). Fixes the real DB's 16 stale keys.
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).
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.
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.
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.

⚠️ 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

Commit this branch (code + docs, one commit), then merge/PR per Good Dog Rule (one integration test ✓).
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.
Then relaunch app once so the user's real %APPDATA% DB self-heals on load + first save purges stale keys.
