Creator ruling 2026-11-12, the parts that were unambiguous:
- The back chevron is gone from the left of the output line.
- "Output" gains a colon and takes the same 11 px muted style as "One output at a time".
- "press <esc> to return" sits centred under the switch pair.
- Esc actually returns from the Output world (MainWindow_PreviewKeyDown -> EnterBuildWorldCommand).
Without this the bar would have lost its only route back, since the chevron was that route.
UiShellTests guards all four: the colon, the hint, the absence of the chevron tooltip, and the muted
style class of both labels.
680 pass, 0 warnings. The switches' post-click behaviour is still awaiting the creator's mock
description, so this commit deliberately leaves the pill pair alone.
Scope justification: Assets/starting-background.jpg is outside this unit — the creator's replacement art,
still awaiting their visual check.
Reported 2026-11-05: those two tabs stayed open when clicking elsewhere, unlike Stream Settings, YPP
and TEST. All five drawers share one host (TextPullOutHost), but the window's click-outside guard only
listed the other three, so the gear and socials panels had no way to dismiss except their own tab.
The guard now closes them too, and a test pins both directions: an outside click retracts the drawer,
and a click inside it does not.
Creation holds Ctrl (Ctrl+right-click), and Windows repeats a held modifier. The repeat
tick landed after the box existed, so the dismiss handler saw an open box and closed it:
appear, then vanish ~500ms later. Guarded with e.IsRepeat, which only ever skips the
repeat events — a genuine second press still closes the box.
Two creator directives, 2026-11-01.
**Ctrl-down dismisses an open zoom box.** Window-level PreviewKeyDown, so the same hand that
opened it can put it away. It cannot cancel itself at creation: Ctrl is already held before
the right-click that makes the box, so the keydown fires while nothing is open.
**Follow mode, default Anchor.** A PillToggle in App Settings ("Follow the box"), persisted
as Zoom.FollowBox. Off — the default — keeps the 2026-10-08 model: the capture stays on the
clicked point and dragging only moves the box over it. On, UpdateZoomMove re-anchors the
capture to the box centre (half the box's size, clamped per axis), so the magnifier shows
whatever it hovers. Flipping to Follow while the box is open snaps it immediately.
Three tests: anchor drags leave CaptureX alone, follow moves it to the expected quarter-offset
centre, and the setting round-trips through LayoutStore (tested against the store, not via two
view models — two live VMs fight over the temp DB, which is a fixture problem, not a bug).
Both new test classes share a collection tag: MainViewModel.LayoutPathOverride is static, and
xUnit runs classes in parallel, so without it the two view models collided (one failure in a
combined run, clean when run apart).
Release build 0 warnings; 14 tests pass across zoom, entitlement and preview history. Debug
build is blocked by the running app (PID 47388) — close it and the exe updates.
- TopBar: EDIT ToggleButton, spaced from the REC/ON-AIR segments
- MainViewModel: explicit EditingActive drives IsEditMode; YouTube go-live turns edit off, stop turns it on
- SceneThumbnailStrip: tiles fixed 196x130 and centered; dark background fills the column so its edge does not move on resize; strip row fixed 154px
- MainWindow: left column fixed at 360px; WIDTHS diagnostic log on resize
Not pushed.
Creator ruling: open in the upper-left of the screen with ~75px padding. The
restore path was placing the window below the fold.
RestoreWindowGeometry now ignores the saved position and calls the pure
TopLeftPlacement(workArea, w, h, padding): work-area origin + LaunchPadding
(75, in DIPs so it scales with DPI), clamped so the window is never pushed
off-screen. A window that fits stays wholly visible; one too big to fit falls
back to the work-area origin.
Size and maximized state are still persisted -- only position was dropped. The
size clamp is unchanged (saved values clamp to [MinWidth, work.Width], which is
why a saved 800x500 returns as 1366x768 per the XAML minimums).
The old clamp tolerated Left as low as work.Left - width + 120 and Top up to
work.Bottom - 80, ranges wide enough to leave the window almost entirely
off-screen while still looking like a successful clamp. A clamp that permits
the window to be unreachable is worse than none: it reads as a guarantee it
does not keep.
BroadcastPullOutTests is renamed ..._Window_Launches_TopLeft_... and now asserts
the constructor applies the derived placement for both an on-screen and a -99999
saved position. Placement math is covered by WindowPlacementTests as a pure
function needing no HWND.
Suite 395/395, 0 warnings.
Creator: 'when the test slide-out is active, then any click off the div should
close the div — this behaviour applies to all tabs, not just TEST.'
MainWindow.Window_PreviewMouseLeftButtonDown already closed the Stream Settings
and YPP drawers on any click outside TextPullOutHost, but its close list skipped
TestSession — so the TEST drawer never dismissed on an outside click.
Fix: run TestSession.CloseDrawerCommand in the same outside-click branch.
All three drawers share the rail host, so the containment check is unchanged.
Good Dog: ONE integration test — the existing TestStream window section now
raises a window-root PreviewMouseLeftButtonDown (source = window => outside the
rail; deterministic, no OS mouse) and asserts the TEST and Stream Settings
drawers both close. Gate: clean build 0 warnings, full vstest 318/318.
Current-OAuth-scope data, no re-consent: subscriber bars for both tiers (500 fan-funding /
1,000 ad-revenue; the 2027-02-01 doubling is versioned date-aware data in YppThresholds),
3-uploads/90d, live standing from channels.list auditDetails, self-reported 2FA/AdSense
checkboxes + deep links (Google 2-Step / youtube.com/earn), and the "what counts" education.
Every refresh appends a YppSnapshot (SQLite v10) so the analytics slice has history from day one.
- ChannelStatsService (channels.list statistics,auditDetails,contentDetails + playlistItems.list,
virtual CaptureCurrentAsync = test seam); YppTrackerViewModel mirrors LiveBroadcastFormViewModel.
- MainViewModel.Ypp.cs: Ypp property, ChannelStatsFactoryOverride seam, one-open-at-a-time drawer
exclusivity (both directions); account sign-in/out/restore hooks in Account.cs.
- PreviewPane.xaml: TextPullOutHost is now a drawer bank [broadcast][ypp][stacked white tabs];
outside-click collapse covers both drawers. MainWindow.xaml.cs updated.
- Wait - watchers: the whole feature already reviewed against YouTube's own docs (YPP Earn tab +
API availability) before building — see TASKS/task-39-ypp-journey-tracker.md.
- ONE integration test: YppPullOutTests (snapshot capture/persist + checklist round-trip +
drawer exclusivity). 313/313 pass, 0 warnings.
- Memory in same commit: TASKS.md row, ai.md Journey-tracker bullet (roadmap→reality), HANDOFF.md.
Slice 2 (Analytics yt-analytics.readonly re-consent → watch-hours/Shorts + velocity/ETA +
sparkline) is queued behind this, not merged.
The ~30Hz CapturePreviewAsync PNG poll capped real cadence at ~20Hz
(35–165ms full-HD encode+decode), so a 60fps widget still juddered at ~1/6
speed. Replaced polling with frame-driven capture of the composition
controller's root visual — the mechanism WebView2CompositionControl and
Flutter's webview_windows use (graphics_context.cc captures the root
surface_ visual via CreateGraphicsCaptureItemFromVisual; reference:
github.com/microsoft/Windows.UI.Composition.WinUI / flutter-internal
webview_windows). Frames now arrive at the renderer's own pace; capture
memory is epoch'd ring reuse + one crop-sized shared WriteableBitmap.
New Services/WebCaptureFrameSource.cs owns GraphicsCaptureItem + free-
threaded Direct3D11CaptureFramePool + session (Straight alpha readback,
per-frame FindContentBounds → CropBounds). WebView2Manager reworked around
per-session composition controllers + one UI-thread Compositor created via
the CoreMessaging CreateDispatcherQueueController P/Invoke (the 19041
projection lacks CreateOnCurrentThread); internal seam ctor
(Dispatcher, Func<string,IScreenCaptureSource>?) for hermetic tests.
CaptureScheduler.cs deleted; the three SetCaptureInterval cadence hooks
removed; InitWebView2() moved from MainWindow ctor to Loaded (a parent
HWND must exist for the composition controller); the hidden WebViewHostPanel
overlay deleted. TransparentBackgroundScript unchanged.
Tests: WebView2ManagerTests reworked — 4 control-size + scheduler tests
dropped, FindContentBounds tests moved to WebCaptureFrameSource, ONE
integration test (Frames_PublishCroppedPreview_And_CoalesceToLatest_CarryingCropBounds)
drives the seam with a FakeWebSource + background-STA DispatcherPump.
Suite 293/293, 0 warnings.
NOTE: composition path NOT yet verified on a device — the take is the
next step. Web work committed locally only (no push per standing rule).
Docs same-commit: ai.md Slice 14 + supersede marker on Slice 11, HANDOFF,
MyMistakes (CoreMessaging DQ + namespace-landmine recipe), TASK 17,
Controls/ViewModels/Services indexes.
OverlayHost.xaml(.cs) takes the window-root overlay dialog grid (settings/
bug/feature/about panels); BackToAbout_Click moved in via inherited DataContext.
WebViewHostPanel + ToastArea stay as thin window-root stubs so the WebView2 ctor
init and NotificationService InArea('ToastArea') name lookups are untouched.
This completes Phase 2: MainWindow.xaml is now a 123-line shell.
Zero behavior change; build 0 warnings; 246 pass, only the 2 known failures.
Docs: ViewModels/index.md Phase 2 tracker updated in same commit.
LeftPanel.xaml(.cs) takes the Row 1 Col 0 panel (layers + properties editor and
the live chat list). All property-editor/chat handlers moved into the control
(SourceNameBox edit, AddSourceButton menu, chat autoscroll self-subscribed on
Loaded, mirror/clip-shape, remove-source, background capture change/refresh,
opacity slider label, list drag-to-reorder, snapshot revert/accept family).
Window keeps only shell + routing: ctor wiring (_leftPanel), geometry, hotkeys,
taskbar overlay, BackToAbout, Window_PreviewMouseLeftButtonDown (uses
_leftPanel.IsClickInside), UpdateSelectionOverlay (calls _leftPanel.OnSelectionChanged).
Zero behavior change; build 0 warnings; 246 pass, only the 2 known failures.
Docs: ViewModels/index.md Phase 2 tracker updated in same commit.
SceneThumbnailStrip.xaml(.cs) takes the Row 0 scene-picker strip (ItemsControl
over Scenes with staged/live border highlight); Thumbnail_MouseLeftButtonDown
moved into the control, transitioning via DataContext.TransitionToScene.
Zero behavior change; build 0 warnings; 246 pass, only the 2 known failures.
Docs: ViewModels/index.md Phase 2 tracker updated in the same commit.
PreviewPane.xaml(.cs) takes the center preview (Row 1 Col 1): the 1920x1080
canvas (OverlayCanvas/SelectionOverlay/BrandFlashLayer/SocialBarElement),
the text pull-out drawer, and the live-controls row (TRAX / game / mic meters,
volume sliders, speaker toggles, socials button) inside the preserved
glow/background Border.
Code-behind moved into the control (drive by DataContext==MainViewModel):
preview drag/select/resize/hit-test (Preview_Mouse{Down,Move,Up},
EndPreviewDrag, HitHandle, HitElement), webcam context-menu handlers
(WebcamMenu_ChangeWebcam/SetBorderAnimation/StopBorderAnimation/
FindBorderShape/CreateBorderAnimation/AddDoubleAnimation/SetBorderColor/
HideInScene/Remove), social-bar glow (SocialBar_MouseLeftButtonDown,
SocialsButton_Mouse{Enter,Leave}, SocialGlowTick), audio controls
(VolumeSlider_*, GameVolumeSlider_*, MicSpeaker_*, GameSpeaker_*,
SetSliderValueFromClick, FindParent), and TraxButton_*.
Window keeps the left source/property/chat panel + thumbnail strip + overlay
host, and routes the selection overlay and preview hit-testing through the
control's public surface (_previewPane.UpdateSelectionOverlay(bool),
IsClickInsidePreview/Drawer, PreviewPane.IsDraggableElement). BackgroundMenu_*
stayed in the window because the left-panel source context menu uses them
(the preview's own desktop/refresh menu binds RefreshCaptureCommand instead).
Preserved the outer preview Border (background/glow/margin) that was initially
dropped in the cut — caught and restored before commit. Pruned now-unused usings
(System.Net.Http, Media.Effects, Media.Animation, Media.Imaging, Shapes,
Threading) from MainWindow.xaml.cs.
Zero behavior change; build 0 warnings; 246 pass, only the 2 known failures.
Docs: ViewModels/index.md Phase 2 tracker updated in the same commit.
TopBar.xaml(.cs) takes the Row 0 top controls: logo/About button, REC/ON-AIR
pills + status signs, avatar, Sign In/Start/End buttons. The avatar fetch
(AvatarHttp/_loadedAvatarUrl/LoadAvatarImage/ShowAvatarFallback) moved into the
control with async semantics preserved; the window grabs the control via
FindName in its ctor and calls _topBar.RefreshAvatar() when IsConnected or
AccountAvatarUrl changes (previously OnViewModelPropertyChanged -> LoadAvatarImage).
AccountLight is pure binding (never touched by code-behind) so it moved with the XAML.
Zero behavior change; build 0 warnings; 246 pass, only the 2 known failures.
Also dropped the now-unused System.IO using from MainWindow.xaml.cs.
Docs: ViewModels/index.md Phase 2 tracker updated in the same commit.
New Controls/ folder + namespace ytLive.Controls. BottomBar takes the
Grid.Row=3 footer: gear menu button (with its GearButton_Click handler moved to
the control's code-behind), centered stream-stats (bitrate/FPS/dropped/
duration/health), and the quality dropdown. All bindings inherit the window
DataContext; app-level styles resolve from Themes/Controls.xaml as before.
Zero behavior change; build 0 warnings; 246 pass, only the 2 known failures.
Docs: ViewModels/index.md tracker gains a Phase 2 section in the same commit.
Mic button/sound bar/slider moved from footer into the preview pane
(vertically below the Socials+TRAX row). Bottom bar reduced to a single
row: gear icon left, stream stats centered under preview, resolution
dropdown right. Avatar image only loads when IsConnected fires true — no
stale image from a previous session on startup. Build 0w, 247 tests.
- FindContentBounds already trimmed the bitmap; the grid/box still rendered at the uncropped user
size, so Fill stretched the tight widget into a bigger frame = dead-between-content-and-border.
- ContentCanvasSize maps the crop rect to canvas units (1920/pixW per axis, DPI-correct) and the
preview event now carries (bitmap, canvasW, canvasH).
- OnWebView2PreviewBitmapChanged sets the element Width/Height to that size; the grid and the
SelectionOverlay (both bound to the element's Width/Height) now equal the widget exactly.
- IsPreviewDragging (set in MainWindow drag/resize) suppresses auto-fit mid-gesture.
- Tests 10/10 (alpha bounds, canvas-size mapping incl. DPI, control size); 0 warnings.
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.
- 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
- 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
Skip Thumb clicks (let drag work normally), set value + e.Handled on
track clicks so the RepeatButton's IncreaseLarge/DecreaseLarge can't
override the jumped-to position.
207 tests, 0 warnings.
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 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
- 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
IFfmpegLocator seam that resolves ffmpeg.exe (PATH -> cache -> pinned download),
plus the licensing compliance that makes a paid GA product defensible.
NOTE FOR USERS: this change shows NO difference in the app's behavior except a
new top-bar "About" button (opens THIRD-PARTY-NOTICES.txt). It is scaffolding
for the encoder/streaming work.
- Services/Encoder/: IFfmpegLocator + FfmpegLocator. Pin is BtbN lgpl-shared
autobuild-2026-08-09-13-03 (NOT gyan.dev/GPL or static: LGPLv2.1 §6 static
relink material avoided by dynamic linking); extracts ffmpeg.exe + libav*.dll
via a staging dir so a crash never leaves a partial cache
- THIRD-PARTY-NOTICES.txt: LGPL/BSD/MIT notices + source offer, copied to the
build output, surfaced by the About button; v1 gate = bundle full license
texts (TASK 4 requirement 9)
- ai.md "Licensing - do not violate" guardrails (never GPL/nonfree/static/latest-
tag, never link FFmpeg in, never drop notices); TASKS.md + Services/index.md
updated
- Tests: FfmpegLocatorTests - hermetic decision-ladder integration test + shared-
build DLL extraction + edge cases; docs updated (78 tests passing, 0 warnings)
- Meter is a READ-ONLY realtime level display: fill = Math.Min(1, AudioLevel * MicVolume) (AudioLevel = live input from the future mixer, 0 with no input; MicVolume is gain on ambient noise). While the slider is dragged the bar previews the slider position (PreviewMouseLeftButtonDown/Up + LostMouseCapture -> SetVolumeAdjusting); on release it returns to the live level (bounces to 0 with no input). Clicking the meter does nothing.
- MicVolume drives MicMuted (read-only, muted <=> volume 0): sliding to 0 flips the speaker to the red slashed mute icon, sliding up from 0 clears it; speaker button runs volume to 0 or restores the prior level (_volumeBeforeMute, default 0.8) and flashes the meter to the restored position for ~300ms (BeginVolumeFlash/EndVolumeFlash DispatcherTimer, cancelled if the slider is grabbed).
- MIC label opens MicPickerDialog (WinRT audio-capture device enumeration, mirrors camera picker, no new packages); the chosen voice source name shows left-justified INSIDE the meter bar (fill at 75% opacity so text + ruler markings show through).
- New files: Services/IMicrophoneEnumerator, MicrophoneDeviceInfo, WinRtMicrophoneEnumerator; ViewModels/MicPickerViewModel; MicPickerDialog.
- Docs updated (ai.md, TASKS.md, Services/index.md, ViewModels/index.md); build 0 warnings, 65 tests passing
