When the Socials button moved to the preview row, its 220px first column
was removed from the footer grid. The mic meter StackPanel still referenced
Grid.Column=1 which no longer exists — moved to Grid.Column=0. Build 0w.
Encoder dual-output: StreamEnabled/RecordEnabled/RecordPath options; per-output
ffmpeg block (stream ->flv, record ->mp4); throw unless at least one output.
RecordingFile: auto-name ty-<yyyymmdd>-<start hhmm>-0000.mp4, rename-on-stop to
ty-...-<len hhmmss>.mp4 with numeric-suffix on collision. LayoutStore persists
record folder. MainViewModel: REC/ON-AIR pills, status light, single Start<->End
button (replaces Start/Stop variants), StopStream no longer signs out, explicit
session timer. About overlay widened. Sign In label + spacing before Start.
Tests: 244 passed / 246 (2 pre-existing: AudioPipeline gains-mute, RoundClip).
Build 0 warnings. Scope check clean.
Memory-map correction (derived-solution rule, 2026-08-29): image-shrink recipe was
never recorded when first done, so it was re-derived. Added Derived-solution/recipes
rule to AGENTS.md; MyMistakes.md now a permanent recipes registry (records the
verified WPF-imaging shrink recipe); schema.md rows MyMistakes as registry; ai.md
points to the rule. README hero image replaced: 3.2MB screenshot -> 1400x794 ->
188KB docs/ytLlive-preview.jpg (JPEG q82).
The wrapper-excluded content-union crop measured an unsettled layout on NavigationCompleted
(async fonts/images, load animations) and produced a broken/zoomed sliver — the image was gone.
Restoring the exact confirmed-good pipeline; the bounding-box dead-space problem stays open and
will not be touched without explicit approval.
- scrollWidth/scrollHeight returns the whole 1920x1080 canvas for widgets whose body/background
spans it, so the crop kept massive transparent margins and the content floated in the Fill box.
- ContentBoundsScript now unions every visible element's getBoundingClientRect, excluding elements
that span >=98% of the viewport (bodies, full-canvas background layers); full-bleed widgets fall
back to the full rect. Crop taken AT the rect's top-left (l,t) — content pins to bitmap (0,0).
- Web Image explicitly Margin=0 + Left/Top alignment so the frame and widget coincide at the origin.
- Canvas-size render untouched.
Bundle exception (2026-08-27): this lands prior-session work plus today's
transparency fix as one commit per creator instruction.
WebView2Manager (new): off-screen WebView2 control parked at -5000/-5000 in
the window's visual tree, captures via CapturePreviewAsync every 100 ms into
a BGRA8 VideoFrame. Source Width/Height sync to the control via
PropertyChanged. JS transparent-background injection runs on every
NavigationStarting/NavigationCompleted so the page's own CSS does not paint
white over the capture.
Transparency fix: DefaultBackgroundColor = System.Drawing.Color.Transparent
set on the WPF control before EnsureCoreWebView2Async. The WPF SDK doc says
the value is forwarded to the controller on init; the IDL (ICoreWebView2-
Controller2) confirms alpha=0 makes the capture alpha-preserving. The
prior-session 'CoreWebView2.BackgroundColor' path was the wrong property
name and has been replaced.
LayoutStore: WebUri column added (idempotent ALTER TABLE) and round-tripped
on save/load (schema v11).
MainViewModel: WebView2Manager constructed on Loaded; loaded web sources
re-registered; Source.WebUri PropertyChanged forwards to manager.
MainWindow: off-screen host Canvas added to visual tree.
Tests: 3 scale-sync + WebView2_DefaultBackgroundColor_Is_Transparent +
LayoutStorePersistenceTests.WebSource_WebUri_Persists. 234/236 pass
(2 pre-existing failures unchanged).
Scale bug (DPI/physical-pixel mismatch) still open.
Same root cause as IsChatBox — SourceType binding fails on WebcamSceneConfig,
WPF defaults Visibility to Visible without calling the converter.
Added virtual bool IsCountdown on SceneElement, override in Source.
Swapped binding to BoolToVis. Removed dead SourceTypeToVisibility converters.
- Source.ShowDesktop bool persisted in DB (schema migration + LayoutStore)
- ClearBackdropCaptureAsync clears CaptureKey + VideoImageSource for static fallback
- Top bar: red/green/pulsing status light, avatar via BitmapImage, Log In button
- ShowStartStream now requires IsConnected
- RunMockChatPreviewAsync: simple async loop, ChatPreviewEnabled property on Source
- EnsureDefaultBackdrop called on every scene switch, seeds all 5 scenes
- SeedEndingBackdrop replaces existing, SeedChatBackdrop added
- SceneCatalog: Chat scene display name corrected (layer = 'YouTube Chat')
- Left panel spacing consistency, context menu reordered
- Border animation rendering via code-behind Storyboard approach
- 3 new backdrop assets (ending-backdrop.jpg, chat-backdrop.jpg, live-backdrop.jpg)
- Build 0 warnings, 178 tests passing
- Elements panel config UI for ChatBox source (font size slider,
font/member/super-chat/background color inputs, max messages slider,
timestamp/badge toggles)
- Schema migration: 8 new ChatBox columns on Source table (ChatFontSize,
ChatFontColor, ChatBackgroundColor, ChatMaxMessages, ChatShowTimestamps,
ChatShowBadges, ChatMemberColor, ChatSuperChatColor)
- Load/save: Source SELECT and INSERT now include all ChatBox fields
- IsElementsPanelEmpty excludes ChatBox so hint doesn't cover config
- ChatBoxRenderer.cs created: WPF FormattedText + RenderTargetBitmap
renderer for on-stream chat overlay
- Slider bindings set to TwoWay for live propagation
- Assets/llamacasty-icon.png: new brand llama figure (no text)
- Assets/llamacasty-icon.ico: converted from PNG for executable
- Assets/llamacasty-logo.jpg: full logo with text
- ytLive.csproj: updated ApplicationIcon and Resource references
- All XAML windows: updated Icon references to new file
- YouTubeStreamService: added GetBroadcastLiveChatIdAsync to fetch liveChatId from broadcast contentDetails
- YouTubeChatService.Poll(): parse snippet.type to handle textMessageEvent, superChatEvent, newSponsorEvent
- MainViewModel: wire _youtubeChat.Start(liveChatId) in PrepareAndStartLiveAsync after broadcast creation
- MainViewModel: wire _youtubeChat.Stop() in StopStream before encoder stop
- MainViewModel: wire _youtubeChat.Dispose() in Shutdown
- MainWindow.xaml: updated chat DataTemplate with member badge (⭐), Super Chat highlight (💰 + gold border), timestamps (HH:mm)
- MainWindow.xaml.cs: auto-scroll ChatListBox on new messages via CollectionChanged
- Chat lifecycle is non-fatal: failures log and the stream continues without on-panel chat
1. Error text shows in red inside the desktop audio meter bar (scrollable)
when TRAX load or playback fails — user gets feedback, not just a
silent red dot.
2. LoadTrax no longer nulls _music on error — the track path is retained
so the user sees what failed and can retry.
3. OnTraxPlaybackEnded now receives the NAudio exception and surfaces it.
4. TRAX dot is green (playing) or gray (idle/no track) — no more yellow
or red states.

All three element sections (webcam border, countdown, web URI) now use
consistent [✕][✓] button order. Green check buttons enabled with click
handlers that save current values as snapshot baseline — revert undoes
to last accepted state, not initial selection.
Countdown section buttons were swapped (had [✓][✕], now [✕][✓]).
Webcam and web sections already had correct visual order.
1e of 7-issue polish batch. 207 tests, 0 warnings.
The web source section's visibility was bound to SelectedElement.Type
via a converter, but WebcamSceneConfig has no Type property — the WPF
binding path didn't resolve correctly and the section leaked through.
Added IsWebSource virtual property to SceneElement (mirrors existing
IsWebcam pattern), overridden in Source to return
Type == SourceType.WebSource. Section visibility now binds directly to
SelectedElement.IsWebSource via BoolToVis.
1c of 7-issue polish batch. 207 tests, 0 warnings.
Merged the URI TextBox and check/revert buttons into one DockPanel.
TextBox fills remaining space, buttons dock right (✓ rightmost, ✕ left).
No more line-wrapping in the web source config.
1b of 7-issue polish batch. 207 tests, 0 warnings.
The scrollbar lives inside the ScrollViewer, not the StackPanel
(ElementsPanel). Window_PreviewMouseLeftButtonDown was checking
IsDescendantOf against ElementsPanel, so scrollbar clicks fell through
and nulled SelectedElement. Now checks ElementsScrollViewer instead.
1a of 7-issue polish batch. 207 tests, 0 warnings.
- Elements scrollbar no longer deselects element on click (check ScrollViewer, not StackPanel)
- Web source: URI + check/revert buttons merged into single DockPanel row, consistent order (✓ rightmost)
- Countdown timer moved from Elements panel to inline in source list row, range clamped to 1-30 min
- Volume slider click-to-position restored: e.Handled prevents IncreaseLarge from overriding position, Thumb drag still works
- Desktop audio meter: asymmetric smoothing (attack 0.2, decay 0.08) for faster response to silence
- 207 tests passing, 0 warnings
1. About box bg → #0A0C1A (matches icon bg)
2. Elements panel collapses when no element selected / scene changes
3. OpacityChip moved from preview overlay into Elements panel
4. Color picker fix: cast to SceneElement not Source (WebcamSceneConfig was silently blocked)
5. Red left accent bar on selected items in Scene/Source lists
6. ✓ character replaced with Path checkmark icon in Elements panel
7. Removed ToolTip='Applied' from green check buttons
8. Created bugs.md with first entry (iTunes audio on mic meter)
9. Full logo in README + About box uses ytLlive-logo.png
- Removed llama-logo.ico, llama-logo.png, llama-logo-icon.png
- Added tyllive-icon.png (340x318, app icon for all windows + About overlay)
- Added tyllive-icon.ico (multi-size 16/32/48/256, Windows app icon)
- Updated ytLlive-logo.png to new 524x220 branded version with tagline
- Updated ytLive.csproj + all 6 XAML window references
- TRAX: LocalGain now applies 0.2× factor so music is quieter relative to desktop audio slider
- TRAX tooltip: switched to ToolTipService with Placement=Top to fix z-order in Viewbox overlay
- Mic meter: MeterLevel multiplied by 1.2× before clamping for ~20% higher visual readout
- Volume sliders: click anywhere on track to jump thumb to that position before dragging
- Backdrop: Image Visibility now binds to BackdropVisible; compositor checks IsVisible before blit
- Renamed 'Backdrop' to 'Game Capture' in EnsureBackdrop + test assertions
