HANDOFF — Session State

Branch

task26-webcam-menu-gate @ working tree — code + docs complete, NOT yet committed (commit on your word). Parent: task25-backgrounds @ 7dd140a, committed and pushed, clean.

Creator's visual pass of TASK 25 came back green except one item: the (+) menu's Webcam row wasn't greyed out when a webcam was already deployed in another scene. Root cause: CanAddWebcamToStagedScene only checked the staged scene's config; the truth is the _webcam singleton.

Renamed + regated: CanAddWebcamToStagedScene → CanAddWebcam = StagedScene != null && _webcam == null (MainViewModel.cs:308). Raised at all five sites: StagedScene setter, ReacquireWebcam (layout load), OnElementsChanged, _webcam create (AddWebcamToStagedSceneAsync), last-config removal (RemoveElement).
XAML: the Webcam MenuItem's IsEnabled binding renamed to match; tooltip verbatim.
Test (Good Dog Rule — ONE): WebcamMenuGateTests.CanAddWebcam_Gates_On_The_AppWide_Webcam_Identity — real window + temp DB seeded with a Webcam row + one config in Starting; asserts greyed while Live is staged (the old gate's false positive), greyed while Starting staged, re-enabled after RemoveSourceCommand drops the last config, and zero Webcam rows after save.
Suite: 224 total, 223 pass. The only failure is the known pre-existing AudioPipelineTests.Mix_HonorsProviderGains_AndGameMute_KillsTheLoopback (unrelated). Build 0 warnings.
Docs same commit: ai.md (gate rule + rename; dropped the stale "empty-canvas right-click Show Webcam" claim — that XAML never shipped), TASKS.md TASK 3 row 27, this file.
Dead code flagged, not touched: ShowWebcamCommand / CanShowWebcamInStagedScene are wired in the VM but bound nowhere — audit item, separate branch if wanted.

⚠️ 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 ONE (AudioPipelineTests.Mix_HonorsProviderGains_AndGameMute_KillsTheLoopback) — not caused by this branch.
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, 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 ✓).
Creator visual pass on Windows: add a webcam to any scene → the (+) menu's Webcam row greys out everywhere; remove it → row re-enables.
Then merge task25-backgrounds → main (still pending from last session), relaunch app once so the real %APPDATA% DB self-heals.
