Fix logo-click crash (Run is not a Visual); Text tab always visible; avatar initial fallback

HANDOFF.md

@@ -26,6 +26,8 @@
 - **`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`.
+- **Text-tab crash fix (2026-08-24):** clicking any text `Run` (e.g. the LlamaCasty logo) crashed the app — `Window_PreviewMouseLeftButtonDown → IsDescendantOf` used only `VisualTreeHelper.GetParent`, which throws on non-Visuals; now falls back to `LogicalTreeHelper.GetParent`. Landmine for ANY new hit-testing code: text Runs are not Visuals.
+- **Avatar display:** connected-but-image-missing now shows the channel initial in the circle + logs to startup.log (`Avatar load failed` / `connected but no profile image URL`). If the creator reports "no avatar", first check whether the app is actually CONNECTED (green status light vs Log In button) — ending a stream clears the OAuth session by design.
 - **Dead code flagged, not touched:** `ShowWebcamCommand` / `CanShowWebcamInStagedScene` wired but unbound — audit item.

Noise suppression = a **pure-C# noise gate** (creator chose over RNNoise / a second ffmpeg `afftdn` pipe, 2026-08-14 — KISS). Always-on — no UI knobs; the mic stays the creator's single audio control
 27. ✅ **Webcam row gates on the app-wide identity (2026-08-24, TASK 26)** — the (+) menu's Webcam item greys out whenever a webcam exists **anywhere** (`CanAddWebcam` = `StagedScene != null && _webcam == null`; renamed from `CanAddWebcamToStagedScene` whose per-scene rule let a second picker run from a scene lacking the config), raised at both `_webcam` mutation sites (create / last-config removal) + scene staging + elements change. Creator's visual pass found it: minis/no-capture-rows/capture-controls all good. ONE integration test `WebcamMenuGateTests.CanAddWebcam_Gates_On_The_AppWide_Webcam_Identity` (real window + temp DB seeded with a webcam in Starting; asserts greyed while Live staged, re-enabled after `RemoveSourceCommand` clears the last config + the `Webcam` DB row). Stale map fixed in the same commit: ai.md's "empty-canvas right-click Show Webcam" claim dropped — that XAML never shipped (`ShowWebcamCommand`/`CanShowWebcamInStagedScene` are wired but unbound dead code, audit item). 224 tests (223 pass; the pre-existing AudioPipelineTests failure is unrelated)
 28. ✅ **YouTube Chat layer: one-per-layout gate + legacy label heal (2026-08-24, TASK 27)** — same rule as TASK 26 applied to the chat layer: the (+) menu's YouTube Chat item greys out while any scene carries a ChatBox source (`CanAddYouTubeChat`, raised on staging + elements change; `AddSource` refuses a second), tooltip "One chat layer at a time — it's already in your stream". Plus the creator's label fix: layers added by commit `65641d8` were named "Chat"; LoadLayout now heals exactly that un-renamed default to "YouTube Chat" so the Layers row matches the (+) picklist (creator renames untouched, idempotent). ONE integration test `ChatLayerGateTests.LegacyChatName_Heals_And_CanAddYouTubeChat_Gates_On_The_Existing_Layer` (real window + temp DB with a legacy "Chat" row: healed on load + persisted on save, greyed cross-scene and in-scene, re-enabled after remove). 225 tests (224 pass; pre-existing AudioPipelineTests failure unrelated)

White 30px tab, rotated red "Text", right edge vertically centered; click slides a dark 320px drawer left over the preview (200ms CubicEase). Every edit persists to Settings keys (`Broadcast.*`) immediately; **Update Broadcast** button calls the new `YouTubeStreamService.UpdateBroadcast` (PUT `liveBroadcasts?part=snippet,status`, echoes scheduledStartTime because update replaces the whole snippet part). Go Live prefills from the form and captures what was inserted (`CaptureGoLive`). The old un-persisted Default Stream Title/Description fields came OFF the App Settings overlay (replaced by the form); `DefaultStreamTitle/Description` VM properties deleted. **Launch geometry** (same unit): default 1920×1040, MinWidth 1366, MinHeight 768; `WindowStartupLocation=Manual` + window size/position persisted on close via `RestoreBounds` (maximized-safe), restored in ctor clamped to minimums and the primary work area (disconnected-secondary fallback).
