Build 730 (creator):
- Left pill while recording: solid #2ECC71 dot pulsing 1.0 <-> 0.2 on the existing one-second timer, and
"REC: hh:mm:ss" in Consolas so the digits cannot jitter the pill's width. Idle face unchanged.
- Right pill while recording: a stop square and "Stop Recording"; clicking it runs the normal stop, which
halts and resets the clock and returns the pair to "Local MP4" / "Start Recording".
- The separate reality line (dot + REC/LIVE + elapsed + End) is now LIVE-ONLY: a recording would otherwise
print the same three facts twice. RunningVisible is IsLive, and ShowOutputStage no longer hides itself
for a recording (it must be on screen to carry the clock and the stop).
Two rules collided and are now separated rather than merged: a creator's Stop on a recording restores the
Local MP4 pair (build 730), while a pipeline FAILURE still clears both pills (the 2026-09-01 zombie rule).
StopStream(afterFailure:) carries the difference, and the pump-failure path passes it.
RealAppHost.Run was rethrowing with `throw failure;`, which destroyed the original stack — a failing
assertion inside the action reported the wrapper's line instead of its own. ExceptionDispatchInfo now
preserves it; that is how the two failures above were located in one pass instead of five.
680 pass (one audio-pipe instance flake under full-suite load, passes alone), 0 warnings.
Scope justification: Assets/starting-background.jpg is outside this unit — the creator's replacement art,
still awaiting their visual check.
Build 729 (creator):
- "press <esc> to return" loses the word "press"; the label is "Record / Go-Live".
- The bar takes focus on "Build scenes" and Tab cycles between the two halves only
(KeyboardNavigation.TabNavigation="Cycle"), never off into the window.
- Entering Record / Go-Live starts with NOTHING chosen — the output switches are a fresh decision,
not a remembered one.
- Three states: nothing chosen [YouTube][Local MP4]; YouTube chosen [YouTube(red)][Live Stream][Private
Stream]; Local MP4 chosen [Local MP4(red)][Start Recording] → [End Recording] while recording. Only the
chosen output is red; the action chips never highlight. Choosing Local MP4 takes the left slot and the
YouTube chip disappears with it, which is what "slides to the left, replacing it" describes.
"Private Stream" is the private-visibility stream — the same thing this app has always called the test
stream (creator's clarification, so the wording is deliberate, not a new broadcast type).
Output chips are one style with a Tag-driven trigger (OutputChip + OutputChipIcon), so a chip's red face
and its glyph colour can't drift apart; the one-alpha hit-area colour is a token, because
DesignTokensTests rightly refuses literals in theme files.
680 pass, 0 warnings. Scope justification: Assets/starting-background.jpg is outside this unit — the
creator's replacement art, still awaiting their visual check.
Unit C (creator ruling 2026-11-12).
- Local MP4: one button, "Start Recording".
- YouTube: "Private Test Stream" beside "Review & Go Live", the latter with the primary face because it
is the default ask.
- Running: "End Live Stream" (or "End Test" for a test run, "Stop Recording" for a local one).
The behavioural change underneath: SessionStartDecision.For no longer takes `editing`. Since 2026-10-30
EDIT silently chose test-vs-real, which meant the same button did two different things depending on a
toggle three inches away. With Test as its own button that inference has no job, so For() now reads only
the armed output and ON-AIR always means the real livestream. That supersedes the 2026-10-30 ruling;
SessionStartDecisionTests is rewritten to pin the new matrix rather than the old one.
A signed-out press still starts the sign-in flow instead of sitting dead (no-dead-ends), unchanged from
before — now stated in one place, the two new commands, instead of inside a route table.
680 pass, 0 warnings. Scope justification: Assets/starting-background.jpg is outside this unit — the
creator's replacement art, still awaiting their visual check.
Unit B (creator ruling 2026-11-12). Pressing Record / Go Live now changes the bar: the REC/ON-AIR pill
pair becomes two labelled switches with glyphs (the YouTube mark, the record dot), under an "Output"
label and beside "One output at a time". Build world shows nothing but its own segment.
Two things this exposed that were not cosmetic:
- **Local MP4 was not actually the default.** Both pills started unarmed, so the stage opened with no
output selected; the old screen got away with it because the primary button inferred "record" from
"nothing armed". RecordPillOn now starts true, which is what "pos = ON (default)" means in code.
- **The stage gates the whole idle cluster, not just the switch.** Gating only the switch left the start
button visible in the Build world — a Start with no output chosen. ShowOutputStage (output world, idle,
not recording) wraps the cluster, so a running session hides the stage too: its output cannot change.
Exclusivity stays in the view model (arming one drops the other); the XAML merely reflects it.
TopBarWorldTests pins the stage's visibility and the radio pair starting at Local MP4.
680 pass, 0 warnings. Next: unit C (output-dependent primary action, End labels).
Scope justification: Assets/starting-background.jpg is outside this unit — the creator's replacement art,
still awaiting their visual check.
Each finished broadcast is filed locally — tier, probed encoder, rated, settled, steps
spent — and Models/RateHistory turns that into at most a suggestion. The app never
applies one: it asks before the next stream, "Use it" sets the rate, "Keep mine"
remembers that exact number so the same question does not return until the evidence
moves. Nothing leaves the machine.
Two rules keep it from nagging. The high-water mark is the highest rate that
*finished* a session with zero steps, not the highest seen, so one easy session (a
menu screen, a quiet game) cannot set a target the machine cannot hold. And it is
asymmetric: raising needs 10% above the current rate across five clean sessions of the
same tier and encoder, lowering needs three step-downs in five — fixing damage should
not wait for a percentage, and risking it should.
The encoder key is real, not decorative: StreamHealth.VideoEncoder is now filled from
the probe (FfmpegEncoder), so history recorded against NVENC is not applied to a
machine that later runs QSV. At startup, before anything has streamed, the last
session on that tier is the honest guess.
672 pass, 0 warnings.
The tier table cannot know a creator's connection, so it should not pretend to. The
Mbps box under the picker is theirs: the tier chooses geometry and frame rate, the
box chooses bits. Stored per tier (`Video.Rate.<tier>`), so tuning 1080p60 does not
touch 720p30, and none means "the shipped default" rather than zero.
Clamped at the tier's YouTube minimum (`RateLadder`), because a target under it
cannot hold the resolution; no ceiling otherwise, because a wrong guess is exactly
what live step-down exists to catch, and a creator who types 25 on a fibre line
should be allowed to find out. The tooltip carries YouTube's number for the tier.
`MainViewModel.EffectiveQuality` is the single substitution point, and the encoder
options, the step-down policy and the clip buffer all read it — so a rated tier can
never stream at the shipped default because one call site was missed.
One ordering trap found by the test: the constructor resolves the default tier
before the layout store is open, so a read at that point must not cache, or the
shipped default shadows the creator's stored rate for the whole run.
670 pass, 0 warnings.
Every 1080 tier carried 8 Mbps, inherited from TASK 4's "mainstream ceiling,
upload headroom stays comfortable". It was never derived from anything: the same
number served 30 fps and 60 fps, landscape and vertical, which no per-tier
derivation would produce. With CBR now actually holding the rate (700c7a8) that
number becomes the picture quality, so it has to be chosen rather than inherited.
New defaults sit between YouTube's H.264 recommendation (17 at 1080p60, 14 at
1080p30, 8 at 720p — support.google.com/youtube/answer/2853702) and the rate
practitioner OBS guides converge on for YouTube (9–12 Mbps at 1080p60). Vertical
mirrors its landscape pair: 1080x1920 is the same pixel count as 1920x1080.
The free-profile fallback in OutputProfile.Resolve moves with it (8.0 -> 10.0) so
a build with no shipped tiers still emits the 1080p30 rate rather than a stale
one.
668 tests (1 audio-pipe flake under full-suite load, passes alone), 0 warnings.
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.
The last resilience slice. When a drop ends the broadcast, YouTube cannot resume it, so the only way
back is a new one — and that is what the app now offers, in one click.
- `Services/BroadcastTitle.cs` — the resume marker is applied to the title the show was using, and any
existing marker is REPLACED rather than stacked ("Show (resumed)" → "Show (resumed 2)"), with the base
truncated so the whole title fits YouTube's 100-character limit. Otherwise a channel grows two
identically named videos and the creator has to explain it.
- `MainViewModel.BackOnAirCommand` — reuses the ordinary go-live path with the saved details and the
cached stream: new broadcast, new VOD, no dialog. It appears only after a drop ended the session and
the ordinary start button steps aside, so there is exactly one way forward.
- The running line goes red OFF AIR (not amber) in that state; the button reads "● Back on air".
Tests: `BackOnAirTests` — first re-air marks the title, a second drop counts instead of stacking, the
100-character limit holds, an empty title still works, and the post-drop state exposes exactly one
start affordance. FAST gate: 552 passed, 0 failed, 0 warnings.
TASK 32 is now complete: fragmented MP4, blip retry, poll-driven RECONNECTING, ingest pre-flight, Back
on air.
Creator challenge (2026-11-05): "I really don't think that's going to be a constant — it's going to
depend on so many variables, some that are dark to us." Correct, so the measured-grace constant and
the countdown are dropped from the spec. YouTube's cutoff is server-side and depends on ingest health,
prior stream quality, region and load; a pinned number would be a guess wearing a timer, and it would
be wrong exactly when the creator is staring at it.
What ships instead:
- **Amber RECONNECTING** in the top bar with measured facts only: elapsed seconds and the attempt
number ("0:12 · attempt 2 of 4"). The seconds come from a stopwatch started at the drop.
- **The status poll speeds up while recovering** (30 s → 4 s) and drives the sign; it restores 30 s
when recovery ends.
- **`chatEndedEvent`** — already in the chat feed we poll and previously skipped — now raises a signal
that prompts an immediate status check. It never decides anything: `liveBroadcasts.list`
`lifeCycleStatus` stays authoritative, with `liveStreams.list` health as the push-received signal.
- At `complete`: red OFF AIR (the existing stop path) rather than a pretend-live sign.
Tests: `ChatEndedSignalTests` (the marker is not a chat row, the service raises the signal, and a
complete broadcast ends recovery with the honest message). FAST gate: 543 passed, 0 warnings.
Keep non-owner resolution choices visible but muted. Selecting one preserves the free tier and opens About; external navigation is only the explicit llamacasty.com link. Ref: https://streamlabs.com/desktop
Reported: EDIT on + ON-AIR on, signed out → the button reads "Test Stream" and cannot be pressed.
Cause: the primary button bound straight to StartTestCommand, whose CanExecute needs a connection.
StartSession already routed signed-out ON-AIR to the sign-in flow; the test path bypassed it.
The route is now explicit and pure: RouteFor(kind, connected) → SignIn | Record | Live | Test. The
primary command calls SignInAsync for the SignIn route, BeginTestStream for Test, StartSession
otherwise — so the label, the action and the sign-in fallback cannot drift apart. Pinned in
SessionStartDecisionTests for both live and test, connected and not.
Creator ruling (2026-10-30):
- EDIT off + ON-AIR armed → the primary button reads "Go Live" and runs the livestream.
- EDIT on + ON-AIR armed → the same button reads "Test Stream" and runs the test broadcast.
- REC armed (or nothing armed) → "Start Recording", whatever EDIT says; there is no test
recording, and an unarmed start records locally rather than doing nothing.
So the fifth button was redundant: `ShowTestButton` no longer feeds any control. The decision is a
pure function (`Models/SessionStartDecision`) so the whole matrix is testable without a window;
`PrimaryStartCommand` follows the same kind, so label and action cannot disagree.
Guard: SessionStartDecisionTests pins the four cases, including the no-dead-ends fallback that my
first version got wrong (unarmed returned Live instead of Record — the test caught it).
Note for the v1 gate: the "hide TEST at v1" item is now satisfied by construction — the test path
is a mode of the primary button, not a separate control.
The state colours the view-models hand to bindings — top bar, REC/ON-AIR dots, health banner,
meter bands, toast tints — were hex literals in C#. They now resolve from Themes/Tokens.xaml
through `Helpers/ThemeBrush`, so the values live in one place. Without an Application (unit tests)
the helper returns a neutral grey: visibly wrong rather than silently plausible.
Four tokens the code needed and the document lacked, added to DESIGN.md (so the doc-is-the-contract
guard demanded their brushes): info-container #3a3b52, success-container #1d5c38,
warning-container #b8860b, test-container #9c6f1c (the test-stream gold bar).
Also fixed by this: the top bar still painted the RETIRED brand red #e94560 when live — the
standard's #ff5451 now, and `OnAirSignTests` (which pinned the old value) says so. BarOn/BarOff
became properties rather than static fields, because a static field would resolve tokens before
the Application exists.
Verified: DesignTokensTests, GameMeterHonestyTests, NotificationAreaIntegrationTests,
OnAirSignTests, SessionTeardownTests — 38 tests green.
Last inconsistency from the sweep: several VM-side state colours are still literals, and after
the palette moved they disagreed with everything around them — the top bar's LIVE state would
have painted the retired pink-red while the tile beside it used the standard red.
Values aligned (tokenisation of these sites is its own unit — they are strings bound to
Background/Foreground, so the fix is a VM->Brush refactor, not a find/replace):
- live / on-air / recorder dot: #e94560 -> #ff5451 (the standard red)
- error banner: #8f1f1f -> #93000a (error-container)
- audio meter bands follow the doc's stated thresholds: nominal cyan #38bdf8, caution amber
#ffb95f, peak #ff5451 — they were green/yellow/red, which contradicted DESIGN.md's own table
GameMeterHonestyTests pinned the old band colours; its intent (the meter scales by volume) is
unchanged, so the two colour expectations now name the new bands.
- Socials: the dialog is a right-rail drawer (same pattern as Stream Info/YPP/TEST); the live-screen button is removed
- Right rail: Stream Info (was Stream Settings) and YPP show the YouTube logo; Socials and TEST get icons; tab colors and label colors per spec
- Top bar: EDIT toggle beside REC (orange when on, blue when off); going live on YouTube turns it off
- Stream readouts (bitrate, FPS, dropped n (x.y%), Live hh:mm:ss, health) and the resolution dropdown moved to the top-left cell; bottom bar emptied at the same height
- Webcam border drawing restored (it was removed with the CRT bezel change)
- YouTube chat layer: border color, thickness, and opacity controls
- Vertical 1080p30 tier added
Not related to the fps gate yet; no gating is enforced.
The creator's locked table (2026-10-17) gives the Chat scene its own rules in
the 9:16 tier: RECT ONLY - the circle option is not offered - and a size that
is either the normal small tile or ENLARGED to fill one whole 607x540 area
(top or bottom). Unit 1 shipped the per-scene placement; this unit is the Chat
scene's own variant of it.
The rule lives on the MODEL, not on the button:
- Models/SceneElement.cs: ClipShape and ToggleClipShape() are now virtual.
- Models/WebcamSceneConfig.cs: VerticalShapeLocked (set per scene by the VM)
OVERRIDES the ClipShape property, so no writer can slip a circle in - the
toggle, the Shape button and the placement swap all go through it. The lock
is cleared BEFORE the 16:9 layout comes back, so the desktop shape returns.
- ViewModels/MainViewModel.Webcam.cs: CanToggleClipShape (the circle is NOT
offered in the vertical Chat layout - the Shape button disappears, it is not
merely greyed out), IsChatSceneCamera, ResizeWebcamInVerticalTier.
- Models/VerticalCameraLayout.cs: FillsArea (the "enlarged" state, derived -
no new column) and SizeFor - the Chat camera's TWO sizes, the tile or the
whole area, whichever is nearer the requested width, so the resize handle
has two detents instead of any size in between.
- An enlarged camera FILLS the area its centre is in (top or bottom), so
dragging it up/down swaps the areas.
- The Chat camera is auto-tiled like the Live one when the vertical tier is
picked - otherwise the vertical chat stream has no camera at all.
- Controls/PreviewPane.xaml.cs: the resize routes through the VM; the drag
assigns, lets the model clamp into the band, then snaps (so the enlarged
camera can be dragged from the top area to the bottom one).
Test: ytLive.Tests/VerticalChatCameraLayoutTests.cs - the ONE Good Dog test for
the unit: the vertical tier is picked -> the Chat camera comes into the band as
a small RECT tile -> the circle option is not offered and cannot be set even on
the model -> dragged up and enlarged it fills the TOP area exactly -> back to
16:9 the desktop layout is restored exactly and the circle option is offered
again. 430/430 tests pass, 0 warnings.
Research (the creator's table is the established practice, not our invention):
- Streamlabs' vertical guide: "splitting the screen in half horizontally,
placing the camera feed in the top half and the main content on the bottom
(or vice versa) may be the bet", and a just-chatting vertical wants the
camera "to take up most of the screen"
(streamlabs.com/content-hub/post/overlays-vertical-and-horizontal-streaming)
- Bloopbot's vertical overlay docs describe the same per-layer model we use at
scene granularity: "move or resize a layer on Vertical and it stops being
Auto-placed. It keeps the place you gave it, and the horizontal layout is not
touched" (bloopbot.com/docs/vertical-overlays-twitch-dual-format) - our
swap-at-tier-change, stored per scene.
- Landmine recorded: "about the bottom 560 px of the vertical video can be
covered by Twitch's chat and player controls on phones" (Bloopbot) - the Chat
camera's enlarged BOTTOM area may be half-hidden by the platform chrome;
TASK 53's safe-zone work decides that.
Memory in the same commit: ai.md (the Chat rules, the shape lock, the tests),
TASKS.md + TASKS/task-57-vertical-camera-layout.md (TASK 57 complete), HANDOFF.md,

for a discrete size set; the edit tool cannot match an oldString with an em
dash), Models/ViewModels/Controls index rows.
The vertical tier is a centred band crop of the SAME 1920x1080 master (band x
656.25, w 607.5, h 1080), so the 16:9 camera placement (x~1408) falls outside the
cropped window and the creator is simply not in the vertical stream. Each scene
now keeps its own vertical position, size and shape; switching back to 16:9
restores the desktop layout exactly (the creator's locked table, 2026-10-17).
Geometry only - NO render-path change. The preview and the compositor both read
the element's own X/Y/W/H + ClipShape, so the tier switch swaps the LIVE geometry:
- Models/VerticalCameraLayout.cs (new): the pure math - the band, its two 607x540
areas, the six spots (top/bottom x left/centre/right), the 32px inset and the
270x152 default tile (480x270 in the 1080x1920 output) in the bottom-right spot,
the corner the 16:9 default webcam uses.
- Models/WebcamSceneConfig.cs: the vertical placement lives in seven additive
columns (VerticalX/Y/Width/Height/ClipShape/RectWidth/RectHeight; NULL = "this
scene has no vertical placement yet"). The 16:9 layout stays in the old columns
and is parked in the transient Landscape* fields while the vertical tier is
live; Begin/EndVerticalLayout + CommitLiveLayoutToVertical do the swap. The
X/Y/W/H overrides clamp every write into the band - outside it the camera is
invisible in the vertical output.
- Models/SceneElement.cs: X/Y/Width/Height became virtual so the derived element
constrains every writer (drag, resize handle, typed fields) in ONE choke point
instead of three writers each re-implementing the rule.
- ViewModels/MainViewModel.Webcam.cs + .Streaming.cs: IsVerticalTier/VerticalBand,
ResolveVerticalCameraLayout(s) (the tier swap), MoveWebcamInVerticalTier /
SnapWebcamInVerticalTier (the six-spot snap, by the tile's centre),
EnsureVerticalCameraLayout; ApplyStreamQuality is the tier-change hook. The
Live scene gets its small tile automatically on the first vertical switch (the
vertical stream would otherwise have no camera at all); the other scenes keep
their 16:9 placement until the creator drags them into the band.
- Controls/PreviewPane.xaml.cs: the drag/resize route through the VM snap under
the vertical tier instead of free-floating over the master.
Controls/LeftPanel.xaml: the webcam properties gained a Geometry section
(X/Y/W/H) for the manual entry the creator asked for, bound to the LIVE
placement, gated on the VM's IsWebcamSelected (NOT SelectedElement.IsWebcam -
the TASK 51 test finds that panel by binding text and would match twice).
- The store: seven guarded ADD COLUMNs, the INSERT/SELECT extended, and the
X/Y/W/H/ClipShape columns stay the 16:9 layout - while the vertical tier is
live the save writes the parked values there and the live ones into Vertical*.
Test: ytLive.Tests/VerticalWebcamLayoutTests.cs - the ONE Good Dog test. The
vertical tier brings the Live camera INTO the band as a small tile; dragging it to
the top-right lands it top-right inside the band; back to 16:9 the desktop layout
is restored exactly (1408/778/480x270); both placements survive a save + reload.

Derivative work: OBS has no built-in per-aspect-ratio layout storage - the
maintainers' answer is "create a second scene and add the scene you want to send
as source" (obsproject.com/forum/threads/161307) - and Streamyard's dual-aspect
guide says the same ("no built-in way to store separate layouts per aspect ratio",
so you rely on manual workarounds and plugins):
https://streamyard.com/blog/dual-aspect-ratio-streaming-tool
Our per-scene, per-tier stored placement, resolved on the tier change, is the

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.

The logs answered the question and closed off a whole branch of investigation.
The long run: broadcast inserted 14:17:04.577, ffmpeg to
rtmp://a.rtmp.youtube.com/live2/5f6z-... at 14:17:05.686, and ffmpeg's own
muxing summary at 14:18:56.473 reads
video:101229KiB audio:1419KiB muxing overhead: 0.202949%
~99MB of real video plus audio over 112s, which is what 8000+128 kb/s is
supposed to produce. No socket error, no 4xx from ingest, no reconnect. And the
broadcast still never left `ready`; close-out 403'd invalidTransition again. The
8s run behaved the same way, so "YouTube needed longer" is disproven — 112s is
longer.
So the RTMP path is provably healthy. That is the finding worth keeping: it
kills the entire "the push is broken" theory, which is where this had been
heading for a week. The break is between ingest being accepted and the broadcast
being told to start.
Which puts the binding in frame, and the app was structurally blind to it.
Google documents contentDetails.boundStreamId and says enableAutoStart fires
"when you start streaming video on the bound live stream" — both valid on
insert, neither restricted against reusable streams. But the migration guide
also says a broadcast "is not bound to any streams at the time that it's
created", and the failure that produces is invisible from the RTMP side
precisely because a reusable stream will happily accept bytes for an unbound
broadcast. Ingest succeeding proves nothing.
Hence LogBroadcastDiagnosticsAsync, riding the existing health poll rather than
adding a timer. One greppable line: lifecycle status, privacy, recording,
boundStreamId *compared against the stream id we are actually pushing*
(BoundMatches: yes / MISMATCH / NO-BINDING / unknown), boundStreamLastUpdate-
TimeMs, autoStart/Stop, liveChatId presence, the stream's own streamStatus and
activeLiveChatId, and the CDN settings we declared.
Deliberately self-limiting: _broadcastSeenLive latches on live/liveStarting so
the diagnostic shouts only while the broadcast is stuck and goes quiet once it
is healthy. A permanent per-tick log line would be noise; this is the opposite.
One test, per the Good Dog rule: BroadcastBindingTests pins the matrix and
specifically pins `unknown` when there is no stream id to compare against, so a
missing expectation can never be misreported as a match — that is the failure
that would make this diagnostic lie.

Creator on the live build: 'why do you make the youtube user icon go away?'
The TASK 42 one-surface bar had scoped the account zone to Stream only
('Record world has no YouTube identity at all'), so arming REC dropped the
avatar and the bar height bounced with it ('really fucking annoying').
Fix: ShowSignInButton / ShowAvatarButton are now plain !IsConnected /
IsConnected — app-level identity, present in both worlds, so the right
column never pops in/out and the bar height stays pinned. Test remains a
child of Stream (still stream-armed AND signed-in).
TopBarModeTests updated to the new contract: signed-out Record world shows
Sign In; flipping back to REC keeps the avatar. PillRadioTests untouched
(it only exercises the ON-AIR face). Docs corrected in-place (ai.md state
model, TASK 42 scope). Gate: clean build 0-warnings, 316/316, scope passed.
The bar now renders ONE surface from the FIRST decision the creator makes —
Record or Stream — with each world being the whole bar. Creator directive:
"I wrote the fucking thing and I still can't figure-out how to do stuff",
"forget this one dog plan bullshit". OBS/streaming-tool reference for the
one-surface paradigm: https://obsproject.com (single mode toggle + context
actions) — cited per spin-guard habit; the go-live/test pattern follows
CEV (https://cev-desktop.aSean.xyz) precedent.
- Mode: single segmented REC|ON-AIR switch (SegmentToggle/SegmentLabel in
Themes/Controls.xaml); radio-exclusive world selection, one tap to flip.
- Record world: switch + Start Recording, zero YouTube identity.
- Stream world: switch + Go Live + Test + account zone right (Sign In until
connected, then avatar with Change Account/Logout context menu).
- Test is a child of Stream: procs only stream-armed AND signed-in.
- Running: one reality line "dot word elapsed" (REC/LIVE/TEST; green/red/
gold) + End; worlds + switch retire.
- Gear moved up from bottom bar, ~3 wordmark letters past the brand, single
click opens Settings/Bug/Feature/About menu (TASK 40 Unit B shipped early).
- Fix folded in: BeginTestStream now arms OnAirPillOn explicitly (unarmed
pump booted with zero encoder outputs -> "At least one output is required"
forced-stop cascade from TASK 41's pipeline).
- VM: world/reality props + RaiseTopBarModes() wired into StreamStatus,
pill, IsRecording, IsTestStream, IsConnected setters.

Tests: TopBarModeTests.cs (new Good Dog), PillRadioTests + TestStreamTests
gates updated. Build 0 warnings; full suite 314/315 — single abort is the
pre-existing env-dependent RealMouseDrag test (Path of Exile 2 running)
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.
The record-OR-live ruling (2026-09-01) was documented in ai.md but the
'pills = radios' UI constraint never landed — both pills could be armed and
StartSession/BuildEncoderOptions would dual-encode to the YouTube ingest AND
a local file at once, streaming a concurrent disk write off the same ingested
Kbps (cripples the stream on mid-range chassis; 'the VOD is already the copy').
The pill setters now clear one another (silent mutual clear); the dual-block
ffmpeg machinery stays generic and unreachable from the UI by design.
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.
Creator ruling 2026-09-01 (stuck REC pill after the failed first recording):
- StopStream clears RecordPillOn + OnAirPillOn — intent resets with reality.
- OnFramePumpFailed: dispatcher-marshalled FULL rollback via StopStream (was:
toast + Error-status only when live — record-only sessions zombied with
IsRecording=true over a dead encoder; the 20:34 attempt proved it). Toast copy
says 'Recording stopped' vs 'stream pipeline stopped'.
- Same zombie class in the three go-live prep failure branches: StreamStatus.Error
limbo replaced by StopStream() (audio loop + recording + pills unwind; a created
broadcast still gets the close-out).
- AudioMixer.StopLive made explicitly idempotent (Stop() twice, rollback paths that
never reached StartLive).
- Seams: OnFramePumpFailed + IsRecording setter internal (InternalsVisibleTo; test
pattern mirrors LayoutPathOverride).
ONE integration test: SessionTeardownTests (real window + temp DB: pump death with
lit pill -> no zombie, no End button, Offline). AudioPipelineTests confirmed to hang
STANDALONE (pre-existing, the declared-known audio class) — ai.md test-count
paragraph corrected to stop claiming a suite total that cannot currently be measured.
The original premise (extract FFmpegEncoder / StreamHealthMonitor / FramePump
classes) was a no-op — those already exist as Services/Encoder/FfmpegEncoder.cs
and Services/Encoder/FramePump.cs. The honest functional seam was the local
recording-output concern, which was interleaved with live-stream orchestration:
- New MainViewModel.Recording.cs (121): StartRecordFile, FinalizeRecordingAsync,
UniquePath, ChooseRecordFolder, ResetRecordFolder, DefaultRecordFolder + the
recording fields (_recordFolder, RecordFolderDisplay, _activeRecordPath,
_recordStartTime, _recordLength).
- MainViewModel.Streaming.Operations.cs 475 -> 377 (keeps live session lifecycle,
health, visuals).
- MainViewModel.Streaming.cs 328 -> 323 (keeps pills/state/properties intact).
Same partial class — all MVVM bound-property glue untouched, no behavior change.
Build 0 warnings; 246 pass, only the 2 known failures.
Docs: ViewModels/index.md tracker updated in same commit.
Streaming.cs 789 -> 330. Moved the go-live/record/health operation bodies into a
new MainViewModel.Streaming.Operations.cs partial (459 lines: StartSession,
BeginRecordOnly, BeginGoLive, StartRecordFile, PrepareAndStartLiveAsync,
PollHealthAsync/OnHealthPollTick/ApplyHealthIssue, StopStream,
FinalizeRecordingAsync, UniquePath, Choose/ResetRecordFolder, DefaultRecordFolder,
OnFramePumpFailed/HealthUpdated, ApplyHealth, ResetHealth, BuildEncoderOptions).
Streaming.cs keeps state, quality/resolution tiers, session timer, command
declarations. Pruned dead usings in both files.
Zero behavior change; build 0 warnings; 246 pass, only the 2 known failures.
Docs: ViewModels/index.md Phase 3 tracker updated in same commit.
MainViewModel.Streaming.cs (787 lines) takes the full go-live/record flow
(StartSession/BeginRecordOnly/BeginGoLive/PrepareAndStartLiveAsync/StopStream,
record-file naming + rename-on-stop), health pipeline (FramePump.Handle +
poll, report-by-exception banner), session timer, REC/ON-AIR start/end UI,
the resolution quality dropdown over the 1920x1080 master, live window
visual tokens (UpdateLiveVisuals), record-folder commands, broadcast
pull-out (CurrentBroadcastId/BroadcastForm) and the stream-state setters
(StreamStatus/StreamVisibility) + their fields. Core drops 1890 -> 1119
lines. Cross-partial references (IsConnected, IsEditMode, BrandFlash*,
_audioMixer, ctor wiring) are safe on one partial class.
Zero behavior change; build 0 warnings; 246 pass, only the 2 known
pre-existing failures (audio-mix gain + round-clip grab). Docs: index.md
Streaming row added + core row trimmed in the same commit.
