Test button next to Start runs the real private-only go-live pipeline as a
session variant (IsTestStream): BeginTestStream -> extracted
StartStreamingSession(alsoRecord:false) shared with the dialog path — no Go
Live dialog, no 'last live' stamp, no recording. Gold top bar + TEST badge +
'End Test' button face; TEST drawer (third right-rail pull-out, three-way
exclusivity) auto-opens once the liveChatId resolves.
Chat tooling: Mock Chat Input sends a REAL liveChat/messages.insert
(YouTubeStreamService.InsertChatMessageAsync) that round-trips the real ~2s
poll and renders through the live overlay; simulated Subscriber/New
Member/Super Chat events inject through the poller's MessageReceived seam
(YouTubeChatService.InjectSimulatedMessage, ChatMessage.IsSimulated) — the
insert API only creates textMessageEvent, so non-text events are local-only
by design (ref: developers.google.com/youtube/v3/live/docs/liveChatMessages/insert).
Scopes youtube + youtube.force-ssl already cover insert; no re-consent.
Good Dog: ytLive.Tests/TestStreamTests.cs — coordinator protocol with fake
HTTP + real-window drawer exclusivity/gate. 0 warnings; 314/314 pass (clean
run; intermittent host abort is the pre-existing WinRT-webcam flake).
Docs ride in the same change: TASKS.md row 41, TASKS/task-41-test-stream-mode.md,
ai.md (YouTube Live API constraints), HANDOFF rewrite.
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.
Click-to-pin an open window as the full-bleed Live backdrop, via the existing
window:<hwnd> capture path (same render layer as game/desktop). Session-scoped:
window:/picker: keys heal to auto on reload (HWND-recycle hazard); pin wins
while the window enumerates, then auto-fallbacks (game → desktop → static); a
dead window's capture session heals to auto, no dead ends.
Fix: ScreenCaptureSourceFactory.Resolve hex-parsed "window:0x<Hwnd>" WITHOUT
stripping the 0x prefix — NumberStyles.HexNumber rejects it, so every pin
resolved null ("No capture target for this key") and the heal silently rolled
back. Same flaw in IsAliveWindowPin (pin-wins guard was dead). Both fixed.
Commit also carries an out-of-scope prerequisite: PillRadioTests.cs:105 had a
committed stray token ("...PrimaryStartButtonLabel soil;", CS1003) blocking the
whole test-project compile — token removed.
Plus the previous session's uncommitted pricing docs (one-time $29/$49) that
share TASKS.md/ai.md/HANDOFF.md.
List_PreviewMouseMove reorders StagedScene.Elements via RemoveAt/Insert,
bypassing SceneGraph's mutation surface, but never scheduled a save — the
new z-order was lost on restart. The drop now sets _dragReordered and
EndListDrag funnels it through MainViewModel.OnSceneElementsReordered()
(InvalidateBake + ScheduleSave, same background-save path as every other
mutation). Integration test (RealApp + temp DB) reproduces the exact
code-behind mutation and asserts the debounced save lands the new Source
SortOrder. Derivation reference: standard WPF ItemsControl drag-reorder
pattern (OBS layering semantics: bottom-most layer = index 0).
Chat's camera no longer greys Web Cam in Live (per-scene max, not app-wide);
TASK 26 superseded by creator directive (app-level resource model). Add Webcam
now places the existing app default without the picker; the picker runs only
for the initial selection. Removing the last placement keeps the identity
(_webcam never nulled) so Add stays offered. Startup pass adopts a solo camera
as the app default, so a clean layout offers the layer in Live/Chat at once.
Dynamic WebcamAddToolTip names the why (incl. the 'graduated to OBS' line).
Good Dog: WebcamMenuGateTests rewritten (real app + temp DB + camera seams) —
identity in Chat does not gray Live; Add in Live places same wc-1 no picker;
scene-with-placement stays gray; identity survives both removals (DB row 1).
WebcamStartupResourceTests single-lock fact asserts CanAddWebcam after adoption.
Docs same commit (ai.md supersession, TASKS.md, HANDOFF.md). 304/304, 0 warnings.
The creator couldn't add a webcam to Live (grayed app-wide) and nothing in the
app explained why. Ground truth from the live DB: one Webcam identity AND one
WebcamSceneConfig in the Chat scene — so the gray was the single-identity rule
working, but the reason was unobservable. This slice makes the webcam a
resource the app validates and locks, mirroring how OBS reserves its devices.
At startup we enumerate the OS once (ValidateWebcamResourceStartupAsync, fired
after LoadLayout, stored as WebcamStartupValidationTask for tests to await):
- 0 webcams -> app runs on, layer inactive, no alarm
- exactly 1 -> attempt CameraManager.AcquireAsync as an app-wide lock; on
failure show a persistent red alert at the bottom of the Layers panel
(WebcamLockAlert + Retry) that re-polls every 5s and clears itself the
moment the camera locks, or on any first real frame
- >=2 -> deliberately no auto-lock; camera selection belongs to the App
Settings dialog (gear) — next slice
CameraManager.IsRunning(deviceId) tells the pass a session already exists
(started OR still starting) so loaded identity configs count as the lock and
the pass never double-acquires. Test seams mirror LayoutPathOverride:
CameraEnumeratorOverride / CameraFrameSourceFactoryOverride so the startup
probe never touches real hardware under test.
Good Dog test: WebcamStartupResourceTests x3 — single-cam locked + app runs on,
zero-cams no-alarm/no-lock, lock-fails -> red alert -> Retry -> clears. Full
suite 304/304, build 0 warnings, scope-check passed.
Docs in-commit: TASKS Open items + ai.md Webcam section + HANDOFF rewrite.
Also corrects the record: 'NVIDIA Broadcast opens the webcam exclusively' was a
suspect-list claim (CameraConflictProbe reads process names only, no handles)
— not restated as fact.
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).

Positive offsets still delay the whole mix via the delay line (lip-sync fix);
negative offsets now ARM once at StartLive and drop |N| ms off the pipe's write
head so audio events land earlier when audio runs BEHIND video. Slider relabeled
AUDIO SYNC, Min −500, locked while live/recording (IsEditMode). LayoutStore and
VM clamp to −500..500.
OBS reference for eat-the-head negative sync: https://obsproject.com/kb/obs-studio/buffering-time (negative sync values pull audio earlier by discarding buffered player audio).
Test: StartLive_NegativeOffset_AdvancesAudio_ByDroppingTheStreamHead (6x0.9 head
must be eaten before 0.2 bed reaches the wire).
Roll-forward of today-slices 6fd1d9c onto the slice-8 base, two-loop hunk dropped.
Release counter (per-build GUID read as noise; +1 per commit from git rev-list,
baseline 241 -> #13, generated by GenerateBuildStamp; GUID demotes to startup.log).
Tests pinned to Label/#N >= 13; wordmark display test asserts the Label.
Flash fix (take 14 finding): consumer holds must never outlive depth x source
period — 4 slots at high refresh lap ~27ms vs a <=50ms compositor read, so a
recycled slot flashed its new frame over the lagged old one. All shared rings 4->8
(OBS/overlay precedent for ring discipline).
Camera producer now rotates an 8-deep ring + Epoch instead of a fresh ~3.7MB
array per device frame (110-220MB/s LOH churn); WebView2 capture reuses a canvas
scratch + 8-deep output ring + a reused WriteableBitmap instead of two fresh
arrays + a fresh bitmap per 10Hz tick. Paste cache stays identity-keyed (Epoch).
Take 6 measured render 35-41ms — WORSE than take 5's 25.5 — and the run could
not be attributed to a binary: exe mtime != build contents (incremental builds
serve stale exes; a source edit without rebuild is a silent old binary). Three
takes of a perf saga had been judged against builds nobody could prove.
- ytLive.csproj GenerateBuildStamp target: fresh GUID per compile (writes
obj/BuildStamp.g.cs -> Helpers/BuildStamp.Id/BuiltLocal). Deliberately defeats
incremental lies: every 'dotnet build' recompiles the app project.
- Wordmark shows the id as a superscript (TopBar.xaml, x:Static, 9px grey
BaselineAlignment=Superscript); startup.log records 'Build <id> (compiled
<time>)' so every take is cross-readable with the visible UI.
- FramePump stats split the tick: 'avg render Xms (resolve Y), avg submit Z' —
the resolver is timed separately (wrapper resolver on per-tick paths; bake
keeps the raw one) so take 7 names the hot half of 'render' with data.
- Fixed a latent transition-clock bug found on the way: lastTick now restarts
every frame (the branch rework had restarted it only during transitions,
letting a transition begun after idle complete instantly on its first Tick).
ONE integration test family: BuildStampTests (unit: shape) +
BuildStampDisplayTests (RealApp, namescoped FindName on TopBar proves the
wordmark SHOWS the id). 47/47 per-class green, clean build 0 warnings. Docs
same commit. User's top-bar/session spec (re-sent twice) + settled Q&A
decisions folded into HANDOFF Unit B — next work unit after take 7 verdict.
Take two (2026-09-01) three confirmed defects, all from creator feedback + the
new resolver logging:
1. NO WEBCAM IN OUTPUT: WebcamSceneConfig.WebcamId carries the identity GUID;
CameraManager keys sessions by DEVICE id — GetLatestFrame(guid) returned null
forever, the compositor silently dropped the layer while the preview (bitmap
path) looked fine. The resolver logging added in 8dcaee0 caught it red-handed.
DeviceKeyForWebcam maps identity->device through the _webcam singleton (identity
mismatch / unknown ids pass through). Test: WebcamOutputKeyTests.
2. START BUTTON VANISHED AFTER STOP: my pills-clear ruling met the old
ShowPrimaryStartButton gate (needed IsConnected or a lit REC pill) — signed-out,
pills-off = blank top bar, no session reachable. Start is now ALWAYS the idle
face; unarmed Start records (local needs no account — no dead-end no-op); the
Sign In button folds into Start's context menu ('Sign in to YouTube', shown while
disconnected) with a dedicated SignInCommand. SessionTeardownTests extended:
stopped session must leave a reachable Start.
3. TOP BAR ORDER (creator spec): [sign light] REC [pill] [sign light] ON-AIR [pill]
— each reality lamp now sits in front of its own intent switch (was: two pills,
then two orphaned dots). Sign labels keep the shared StatusSignText style.
Tests: WebcamOutputKey, SessionTeardown, FramePump, WebcamMenuGate, GlobalHotkey,
BroadcastPullOut — 14/14 across the six classes, clean build 0 warnings.
Phase 2 (refactor-commit-12..18) created Controls/ with 6 UserControls that
split MainWindow.xaml, but no index.md existed — a gap against the schema.md
rule (one index.md per code directory). Documents each control, the window↔
control contract, and the Phase-2 landmines (window-resources converter rule,
control xmlns, name-looked-up host stubs, dropped-Border).
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.
HealthBanner.xaml takes the Row 1 YouTube-health banner (report-by-exception).
Converters: promoted the 7 value<->visibility converters (BoolToVis, Inverse,
NotNull, Null, Hidden, EnumToBool, AllTrueToVis) from MainWindow.Window.Resources
into Themes/Controls.xaml so extracted UserControls can resolve them. AGENTS rule:
controls cannot reach into a window's own named resources; they resolve from the
app-level merged theme instead. Promoted all of them (not just NotNullToVis) so
every pending extraction keeps working without window-level references.
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.
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.
