Add a persisted global App Settings switch. Off keeps the existing per-severity
lifetimes (errors remain sticky); on makes every alert non-expiring and closes
it when its body is clicked. The NotificationService supplies the current
setting to each toast request.
StickyNotificationIntegrationTests covers persistence and both request modes.
618 tests green, clean build with 0 warnings.
Reference: Notification.Wpf exposes a CloseOnClick request option:
https://github.com/G-Stas/Notification.Wpf
App Settings now chooses one of six ToastArea positions (left/right ×
top/center/bottom), defaulting to the existing bottom-right. The setting is
persisted per profile and the toast area moves immediately; edge gutters keep
bottom notifications above the footer.
ToastPositionIntegrationTests covers live repositioning and restart persistence.
617 tests green, clean build with 0 warnings.

Slice 4. 607 green, 0 warnings. Clips remain **off by default** and, while off, the ring is never
constructed — so no reader thread and no encoder output exist until someone asks for the feature.
- **F10** (`HotkeyId.SaveClip`, default F10, remappable in the hotkey dialog) snapshots the ring, writes
the file, prunes to the retention count and toasts the name. Empty ring → "nothing to clip yet"
instead of a zero-byte file; clips off → says so and points at Settings.
- **Settings**: Enable, length (10 or 15, default 10), keep (3/4/5, default 3). Persisted in the layout
store and **coerced on load** — a bad stored value falls back to a legal one, so the ring can never be
sized for a length the UI cannot show.
- The ring is sized from length × tier bitrate × 1.25 and rebuilt if either changes; it is created at
session start and dropped at stop, so memory is only spent while a show is running.
- The drawer states the boundary in the creator's terms: "A capture, not an editor: for trimming,
captions or a library, use a video editor."
Still to come: the replay layer itself (play once then hide in Live, loop the kept clips elsewhere).
The creator's profile still showed the previous Starting art after the replacement, with
`Art.DefaultVersion = 4` recorded — so the version gate had already declared itself done. It
compared a constant against the embedded resource, and those two were compiled at different
moments (version 4 landed with the OLD image embedded; the corrected image reached the assembly
one build later). A version bump can always be raced that way.
The seed now compares BYTES: `LayoutStore.AssetMatches` hashes the bundled resource and checks the
row the background already points at. Same bytes → leave it untouched (so this is idempotent and
never churns the database). Different bytes → re-stamp. The version constant and its setting are
gone, because a heal that only runs once can silently skip the one launch it was needed for.
`SceneThumbnailTests` planted its own art on a background still flagged as default art — in the
real app that state only ever means stale bundled art, because Browse… sets the path and clears
the flag. The fixture now models a creator's own picture.
Tests: 572 green, 0 warnings. Verified the profile's Starting asset hash (167CDD3B…, the
two-category render) differs from the shipped `starting-background.jpg` (5FC6DD22…), so the next
launch re-seeds it.
Creator supplied a new 2724x1536 image; resampled to the 1920x1080 master and encoded at q3
(2.9 MB → 424 KB, so the shipped asset also got smaller).
- `Assets/starting-background.jpg` — the new art, same filename, so nothing else changes
- `Assets/archive/starting-background-pre-2026-11-06.jpg` — the previous image, kept in the repo. The
csproj lists assets explicitly, so an unreferenced file never ships.
- **Existing layouts would have kept the old art forever**: default backgrounds are hash-keyed into the
layout DB on first seed, and the seed returns early once an AssetId exists. `HealDefaultArtVersion`
bumps `Art.DefaultVersion` to 2 and clears the AssetId of backgrounds still using the DEFAULT (a
creator's custom background is skipped), so the next load re-stamps the new image.
Background tests: 44 passed.
The task asked for a `RewardEvents` table plus a backfill. That would have contradicted the published
promise that no viewer, member or donor information is retained after the session ends, and it would
have meant owning a ledger that YouTube already keeps.
So the report is DERIVED on demand instead:
- `Services/SuperChatEventService.cs` — `superChatEvents.list`, parsed for both event types (a sticker
must not be dropped), authorised by the existing `auth/youtube` scope, so no re-consent.
- `Models/SessionRewardSummary.cs` — rolls events up for the session window with **per-currency totals
that are never summed together** (a $5 and a €5 are not $10). Nothing is written down.
- The YPP drawer gains a **THIS SESSION** section: counts are neutral and always shown when there were
events; money appears only when the creator asks for it. `Show monetary metrics` is a drawer toggle,
persisted, **off by default** — a creator who never monetized is never shown a $0.00.
Also: money is labelled as estimates (removed/refunded events are excluded and totals can be restated
for weeks, not days).
Tests: `SessionRewardReportTests` — both reward types parse, the window makes it a session rather than
a channel report, currencies stay separate, an empty session shows nothing, a sticker-only session
still counts. `BackOnAirTests` moves into the serialised `MainViewModelLayoutPath` collection: it builds
a MainViewModel directly and was flaking against parallel tests that swap the static layout path.
FAST gate: 557 passed, 0 failed, 0 warnings.
Creator design (2026-11-05). A stack of red rows at the top of the left panel, above both mode grids
so it shows while editing and while live, pushing the panel's content down.
- Row 1 is the **Steam licence indicator** and nothing displaces it. It reads as status, not a
warning: "Entitlement 30 fps · Maximum 60 fps", both numbers derived from QualityOptions and
HasProOutput. While higher tiers are unavailable it shows a **pin** (standing indicator, no close
control); once ownership is verified the pin becomes a **close control** and the dismissal is
persisted (`Steam.LicenceIndicatorDismissed`), permanent while ownership holds. Losing ownership
restores it as pinned — a change of state, not a preference. Click → About.
- **Event rows stack beneath, newest first**, one row per episode (an episode advancing its state
updates its own row rather than adding another). Each is dismissible. Click → the Logs tab opens
with that event's sequence range painted red (`HighlightedLogFrom/To` + `LogInRangeConverter`; two
numbers rather than a collection because the log list is virtualised and realised rows do not
re-evaluate on membership changes).
- Replaces the old red panel under the quality picker, which is removed.
- The Steam diagnostic text loses "Contact the creator or support" for a neutral
"Steam licensing is not configured in this build."
Tests: `AttentionAlertStackTests` — pinned first with the status text; owned → closable and the close
survives a reload but ownership loss restores it pinned; pinned cannot be dismissed; event rows LIFO
with in-place episode updates; clicking an event opens Logs and sets its range. AboutHub + Entitlement
tests updated for the removed panel and the new wording. FAST gate: 532 passed, 0 failed, 0 warnings.
TASK 64 slice F — the two things left after the feature worked by hand.
- App Settings → **Video clips → Auto Green/Blue Screen** (off by default). When on, a
high-confidence detected screen is keyed as soon as the clip is added; the panel says
"Removed automatically" so an automatic change is never silent. Medium confidence still
asks, low says nothing — a wrong automatic key eats the picture.
- **A clip is a clip:** the alert box's own replacement clip keys through the same settings
block (one alert box per layout, so its settings are the ones the next alert uses), and
choosing an alert clip runs the same detector. The Green/Blue Screen panel now appears for
a video layer *or* an alert box with a custom clip (`Source.ShowsChromaKey`).
- Spill ships as the creator-facing **Fringe** switch; nothing further to tune behind it.
Test: `ChromaKeyApplyTests` gains the auto-apply case (no click, still explicit in the panel)
and an alert-clip case (its pipe asks ffmpeg for colorkey+despill with the blue screen type).

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.
The marquee now has the dial it needs. `ScoreboardPresenter.PixelsPerSecond` is the single owner of
the range (20-400, default 120), the layer's properties expose it with a live px/s readout, and the
value is persisted as Scoreboard.ScrollSpeed because it is a READABILITY choice — re-dialling it
every launch would be a tax on the creator who needs the strip to be readable.
Advance() still takes an optional override so tests can drive exact distances.
Guard: the presenter test proves speed is real (same elapsed time, twice the speed, different
window) — not a value that is stored and ignored — and the panel test pins the control, its range
and the persistence key.
Creator: "even if it's not visible, we want to avoid polling."
ScoreboardEnabled is the layer's master switch in the properties panel. Off means two things:
- the strip frame is null in every scene (per-scene eye toggles stay independent), and
- the cadence policy returns None at every phase — a scoreboard nobody can see must not spend quota.
The switch is persisted (Scoreboard.Enabled), because one that resets would quietly resume polling.
The polling gate is ScoreboardPollsEnabled: master switch AND at least one scene with a visible
scoreboard — so hiding it in all five scenes also stops the polls.
Guards: ScoreboardCadenceTests adds the switch off across live/test/recording; ScoreboardProperties
pins the checkbox and the VM surface.
Unit 9, the one that matters most for this creator.
MASTER STRIP (top, nearest the preview):
- one ladder fed by the MEASURED mix — `AudioMixer` now measures the buffer the encoder receives
(`MasterLevel`, `MasterImbalanceDb`), so the master cannot show a source instead of the output
- `-12.4 dB` readout, and ONE L/R flag that appears above a 6 dB gap instead of a second ladder
- bitrate / FPS / dropped / duration from the existing health poll
MONO OUTPUT:
- `AudioFold.ToMono` averages each stereo pair into both channels, applied after the limiter and
the sync delay, so the stream AND the recording get what was folded
- `MonoOutput` is persisted (`Audio.MonoOutput`) and restored at startup: an accessibility switch
that resets each session is an accessibility failure
- one click in the strip, remembered forever
Guard: AudioFoldTests (hard-left reaches the right at half amplitude, hard-right — the inaudible
case — reaches the left, centred material keeps its level, mono buffers untouched) and
MasterStripTests (the strip binds the measured mix + the switch, the store round-trips it, and the
fold is the tested helper rather than new arithmetic). 33 audio tests green.
- Source.IsBrandLogo persisted (additive migration); layer healed on load, removal blocked
- Image stored as an asset; settings keep the asset id and file name
- App Settings: Brand Logo file field with Browse
- Default placement top-left; per-scene eye uses the existing element visibility
Test: BrandLogoTests; layout/background tests pass (34). Not pushed.
Right-click in the live preview now procs a box that is actually visible and
populated with the zoomed region, and each Zoom View Shape sculpts the box per
spec. OBS-style derivative: magnifier box shows the composited region and dims
the surroundings (same pattern as OBS "zoom" / preview region highlights).
Root causes of the invisible box (two WPF traps, recorded in MyMistakes.md):
- Empty <VisualBrush Stretch="None"/> used as an OpacityMask paints nothing,
so the mask alpha is 0 and the WHOLE box (border included) went transparent.
- ZoomBox lived inside CanvasGrid while its VisualBrush sampled CanvasGrid — a
circular reference WPF renders as nothing. Hoisted ZoomBox to a sibling of
CanvasGrid inside a new PreviewCanvas wrapper (same 1920x1080 space).
Shape semantics (MainViewModel.ActivateZoom):
- Circle: square, click point = center.
- VerticalRectangle (phone): tall 9:16, click point = top-left corner.
- HorizontalRectangle (tablet): wide 16:9, click point = top-left corner.
- Boxes stay fully inside 1920x1080 via Math.Clamp.
UI: ZoomRectOutline/ZoomCircleOutline shapes replace the square Border;
circle clips the box to an EllipseGeometry; brush Visual released when inactive.
Zoom View Shape dropdown now uses the standard YtComboBox style.
Test (Good Dog rule, one integration test): ZoomBoxInteractionTests verifies
aspect/anchoring/clamp per shape and the matching outline+clip in the real
MainWindow. Full suite 404 passed, 0 warnings.
Memory: HANDOFF.md zoom state updated; WPF VisualBrush traps appended to
MyMistakes.md.
TASK 43's alert box grows a real video celebration. Per-alert IAlertClipDecoder
(ffmpeg bgra + f32le pipes, real-time paced, disposed at drain) plays the shipped
Assets/alert-default.mp4 (stamped into the Asset table at startup) unless the
creator picks their own file — path reference only, never stored in the DB; the
six AlertRenderer animations stay the fallback. ~0.3s fade rides the alpha
envelope on straight-source copies (EOF freeze-frames then fades out); audio
forwards to a new AudioMixer alert ring (8s, 48k stereo) drained at unity — no
duck, creator ruling — scaled by volume × fade. An auto-composed marquee ticker
('Funder — Super Chat · $10.00', 140px/s) scrolls top-of-frame via a
FramePump._alertTicker seam through Render/CompositeLayers, mixed into the cache
signature (dynamic overlay, never baked). New Stream Alerts section in LeftPanel.
Derivative-work references (how OBS/Streamlabs alert boxes do per-alert video):
- https://support.streamlabs.com/hc/en-us/articles/217741147-Setting-Up-Your-Streamlabs-Alerts (custom image/video per alert type + variations)
- https://obsproject.com/kb/stream-tutorial-2-alerts (alert overlay as an on-screen zone)
- https://streamlabs.com/content-hub/widgets/alert-box (per-event alert playback)
Good Dog: AlertLayerVideoTests drives a fake IAlertClipDecoder through the whole
lifecycle in one pass (custom path wins, decoder spawns/disposes, fade envelope
0→127→255, audio volume×fade, ticker scrolls, EOF fade-drain to idle). It caught
the clip branch of Advance not clearing _current before AdvanceToNext — the layer
stayed IsPlaying after drain (MyMistakes post-mortem).
Full vstest 319/319; clean build 0 warnings; scope check green.
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).
LayoutStore.cs 1402 -> 47-line shell + 5 partials, grouped by functionality
(line count is a consequence, not the goal):
- LayoutStore.Migrations.cs: all DB schema migration (EnsureSchema, GetUserVersion,
MigrateSourceTable/WebcamConfigTable/ToV3/SceneTable/SceneSocialBarColumn/
SocialsTable/SocialEntryTable)
- LayoutStore.Load.cs: Load() scene/source read-back
- LayoutStore.Save.cs: Save() full scene tree write
- LayoutStore.Settings.cs: key/value settings + mic/record-folder/reusable-stream
+ license/transition/broadcast/hotkey/window-state GetSetting/UpsertSetting
- LayoutStore.Assets.cs: GetAssetBytes/UpsertAsset blob IO
- LayoutStore.cs: shell — Instance, fields, ctor, Dispose
Converted to public partial class LayoutStore : IDisposable. Pruned per-file
dead usings. Phase 3 DOWN: no production .cs exceeds 500 lines.
Zero behavior change; build 0 warnings; 246 pass, only the 2 known failures.
Docs: ViewModels/index.md Phase 3 tracker updated in same commit.
