Starting a local recording left the idle 'Start Recording' chip on screen and never revealed 'Stop
Recording' — IsRecording raised its own notifications but not the output stage's, so the visibility
bindings were never re-evaluated. The visible chip's command then correctly refused to run (recording was
already in progress), which is the worst shape of bug: a dead button that looks live.
IsRecording and StreamStatus now call RaiseOutputStage(). The regression test asserts the NOTIFICATIONS,
not the property values — reading ShowEndRecordingAction directly passes either way, which is exactly how
this slipped through.
682 pass, 0 warnings.
Closing with a recording active called Shutdown() straight away, which disposed the frame pump and the
audio mixer underneath a running loop: ffmpeg never flushed, the file was never finalized or renamed,
and the pump was torn down mid-iteration. That is the 'app goes autistic on close' report.
MainWindow_Closing now holds the window open, runs StopBeforeShutdownAsync (the ordinary stop, bounded at
~6 s so a stuck encoder cannot make the app unclosable), then closes for real. StopStream already honours
the audio-before-video ordering, so the close path inherits it instead of inventing its own teardown.
Test: with nothing running, closing must not hold the window at all (the fast path stays fast).

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.

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.

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.

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.

Unit A of the top-bar redesign (creator ruling 2026-11-12). The standalone EDIT toggle is gone;
Build Scenes IS edit mode, so "which world am I in?" and "can I edit?" cannot disagree any more.
BarWorld (ViewModels/MainViewModel.TopBar.cs) has two values, Build and Output. Build ships
highlighted at launch and sets EditingActive on; choosing Record / Go Live turns it off. Clicking the
already-highlighted half is deliberately not a no-op: it re-enters that world, which is the only way
back to the layers during a session now that the EDIT button is gone (unit 1 made that legal).
WorldSegmentButton (Themes/Controls.xaml) is a Button, not a ToggleButton, and each half passes its
own flag through Tag to one shared DataTrigger — a ToggleButton would fight the view model and, with a
one-way IsChecked, clear its own binding on first click.
UiShellTests updated where it guarded the old EDIT markup (it now guards the segment). TopBarWorldTests
pins launch state, both transitions, and the re-enter case.

Creator ruling 2026-11-12: "we don't care if a creator wants to edit their scene: move stuff around,
shrink/grow a webcam view, etc. Why not?" Correct — the app was only ever *forcing* EDIT off at
go-live, never enforcing it, so the gun-safety was a habit rather than a rule.
App.LockEditWhileLive ships off: a show no longer takes EDIT away. Turning it on restores the old
behaviour exactly — go-live flips EDIT off and stop flips it back, and only because the lock took it,
so a creator who had already turned EDIT off does not get it handed back on stop.
MainViewModel.ApplyEditLockForSession holds the rule so it is testable without starting a broadcast;
EditWhileLiveTests covers both settings, the round trip, and the "don't hand it back" case. Settings →
Editing carries the checkbox.
This is the first slice of TASK 68 (editing while live).

Both offsets rode the debounced layout save, so a value set seconds before the app closed was lost
without a word. That is what happened to the -130 ms offset on 2026-11-12: two clips were measured
against a setting that was not in force, the numbers disagreed by ~65 ms, and the disagreement was
blamed on the audio path.
Setters now write the row immediately (two tiny rows), keeping ScheduleSave for the rest of the
layout. AudioSyncSettingsTests gains the regression: set both offsets on a view model and read them
back through a fresh store with no debounce flush.
MyMistakes records the general shape — "a setting that didn't stick" is almost always ScheduleSave —
with the check list and the two related rules: offsets never ship with a non-zero default, and
scripts/avsync.py only resolves ~50 ms, so below that the creator's judgement wins.

FfmpegEncoder resolved the encoder name into its OWN StreamHealth instance, while the view
model read CurrentHealth — a different object. So every recorded session was filed as
"unknown", and the rate history's encoder key (evidence about NVENC says nothing about QSV)
had nothing to key on. The name now travels on the encoder interface and the pump forwards
it: IFfmpegEncoder.VideoEncoderName -> FramePump.EncoderName.
Caught while adding it: reading _framePump.EncoderName from RefreshRateProposal throws,
because that call runs at MainViewModel ctor line 354 and the pump is built at line 468.
Eight tests failed with the same NullReferenceException, which took a while to see because
the harness's test output is buffered — the first honest look at per-test logging named it
in one line. Guarded; the history falls back to the last session's encoder for that tier,
which is exactly the pre-first-session case the fallback already existed for.
Tests: FramePumpTests gains the encoder-name assertion (null before start, h264_nvenc
after), and the three fake encoders implement the new member.
675 pass, 0 warnings.
The webcam's frames reach the compositor later than the mic's samples reach the audio
pipe, so the voice runs ahead of the lips. The existing lip-sync offset could not fix
that: it delays the WHOLE mix, which drags desktop and alert audio — neither of which
has a camera to follow — out of sync in the process.
So the delay line learned channels (mono for a source, stereo for the mix, offset always
in milliseconds so the frame count is what stays constant), and FillAndMix runs a second
line over micChunk before the mix. Slider-side: presets off / 150 / 200 in the LIP-SYNC
bay under the whole-mix control, persisted as Audio.MicSyncOffsetMs.
Default 175 ms is the creator's own number for a C920 pipeline (they asked for
+150..+200). It is a setting, not a constant, because the right figure belongs to the
camera and the machine — a faster camera wants less, no camera wants none.
Both delay lines are reconfigured every tick, so the 2026-09-12 trap still applies and is
documented at both sites: a Configure that reallocates discards the buffered voice every
10 ms.
673 pass, 0 warnings. Ear check pending: this is an audio change.
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.
Step-down used a flat 3 Mbps (4 for vertical) as its floor — a number that had
nothing to do with the tier being streamed. With CBR holding the target, that
floor is a real picture-quality floor, so it has to follow YouTube's published
H.264 table (support.google.com/youtube/answer/2853702): 6 at 1080p60, 5 at
1080p30, 3 at 720p.
Models/RateLadder is that table as pure policy. Vertical is not a separate row:
1080x1920 and 1920x1080 are the same pixel count, so the frame rate alone picks
the band. StepDownPolicy takes the floor as an optional constructor argument and
refuses one above the starting rate, so an unusual start cannot begin under its
own floor. Omitted, the historical 3/4 floor still applies, which keeps the
existing policy tests meaningful and lets a caller opt in.
One consequence worth knowing: the three-step budget can stop above the floor
(12 → 9.6 → 7.7 → 6.2 from a 20% loss), so the floor is a limit, not a target.
669 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 frame-rate boundary is correct as a product rule, but it only bites in a
Release build, where DevBuild.IsDevelopment is false and DeveloperMode cannot
unlock anything — exactly the build whose performance numbers are worth reading
(see docs/ai/environment.md: Debug pixel paths are several times slower). 60 fps
could not be tested at all.
OutputProfile.EntitlementEnforced is false: every shipped tier is selectable by
any build, and HasProOutput — the one property the tier setter, the dropdown's
strikethrough and the locked-item style all read — answers yes regardless of
ownership. static readonly rather than const, so the consumed `||` does not fold
into unreachable operand code (same reason as DevBuild.IsDevelopment).
The licence indicator row is suppressed while the switch is off: it exists to
explain what the boundary costs, and claiming "Steam ID Limit: 60fps" to an
unowned build would be a false statement. Docs corrected in place — the enforced
rule is unchanged, only its state is recorded.
Tests: one integration case covers both switch states (unowned build reaches
1080p60 with the switch off, 1080p30 with it on), so flipping at launch leaves no
red test behind. The two suites that anchor on the pinned licence row early-return
while it is absent; EntitlementTests covers that state meanwhile.

Add a persisted global App Settings switch. Off keeps the existing per-severity

608 green, 0 warnings. Completes the layer half of TASK 65.
- **(+) → Replay Clip** adds an ordinary media layer with an app-owned path, one per scene, silent by
default (`MediaMuted`) and looping only outside Live — the compositor needs no special case.
- **F10 saves → the Live layer plays it once, then hides** (`SessionCompleted` → invisible, guard
cleared). Every other scene with a replay layer keeps looping the kept set, advancing on each clip's
completion, wrapping at the end.
- **The guard the creator asked for:** while that Live replay is playing, **F10 is inert** with a plain
explanation. That is what replaces the impossible "exclude the layer from its own clip" — with one
encoder and two muxes the clip *is* the program, so the fix is to not clip a clip.
`ReplayLayerTests` drives the real VM: one layer per scene, muted by default, once-through in Live,
looping in BRB, and a stray F10 with clips off writes nothing.
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).
595 green, 0 warnings. Completes TASK 55 (slice 1, log rotation, shipped 2026-10-22).
- **`AlertClipCleanup`**: the default alert clip is materialised into `%TEMP%` for ffmpeg to read, and
nothing ever deleted it — one orphan per profile that ever played an alert. Now: delete this session's
file in `Shutdown`, and sweep `ytLive-alert-*.mp4` at startup for anything a crash left behind. Only
the prefix we own is touched; a directory is never deleted.
- **`DiskSpaceGuard`**: a recording that dies of a full disk is a trust breach, so the numbers are a
pure policy — refuse to start under **1 GB** (toast; the stream still starts, recording does not),
warn under **5 GB** at start ("about eighty minutes" at 8 Mbps ≈ 3.6 GB/h), and one mid-show warning
under **2 GB** — the last useful moment before the encoder fails for a reason it won't explain.
Unreadable drives (a USB stick that just left) return null and never block a running recording.
Tests are policy-level on purpose: filling a real drive is not a test. `DiskHygieneTests` proves the
sweep only removes our own files and that the thresholds behave at both ends.
591 green, 0 warnings.
- `Scene.SceneMutesMic` / `SceneMutesDesktop` are **nullable booleans**: null = leave the mix alone, so
a scene is passive until the creator says otherwise. Schema columns added, NULL for every existing
layout except one deliberate default.
- **Applied once when the scene takes the PROGRAM output** (`TransitionToScene`, only when live or
recording). Staging a scene offline is auditioning, not a stream edit — the test asserts that.
- **The creator is boss:** a manual mute survives any transition into a scene with no opinion; a scene
that does have one wins on its next entry. `SetMicMuted`/`SetGameMuted` are idempotent so a repeated
"mute" cannot clobber the level that unmute would restore.
- **BRB ships muted** (creator spec) for new layouts *and* via a one-time migration for existing rows
where the creator has never expressed an opinion.
- UI: two three-state checkboxes under the layers list ("When this scene goes live"), styled with
`PropertyPillCheck` so the theme test holds.
`SceneAudioTests` covers the whole rule in one integration test: default state, offline staging does
nothing, live entry mutes, manual unmute survives a passive scene, an opinionated scene wins, desktop
untouched, and all three states roundtrip through save/reload.
Needs the creator's eye: the checkboxes are new chrome in the left panel (indeterminate = passive).
Last slice. 590 green, 0 warnings.
- **Shed before you charge the viewer.** On machine evidence the policy's first act is
`ShedCaptureCadence`: `ScreenCaptureFrameSource` widens its conversion interval 10 ms → 33 ms (≈100
→ 30 conversions/s) through a new `ScreenCaptureManager.ShedLoad`. The output tier, the declared fps
and the viewer's picture are untouched — we stop paying for readbacks we were throwing away. It
costs no step budget; if the starvation persists, the fps ladder runs on the next clean window.
- The shed is reset on every stop path, so a cheap session cannot leave a later one capped.
- **The session line is a Logs-tab line, not a session-report line.** The session report is the money
summary (Super Chats, per currency); quality chatter there would bury the numbers it exists for. The
cause-tagged line already lands in the log at the moment of the step.
TASK 33 is complete: two ladders, budgets, floors, ambiguity, one-way with recovery behind a flag, the
relaunch, the copy, and the cost shed. 18 tests pin the ladders, the copy and the restart.
Slice 3. 589 green, 0 warnings.
- **`FramePump.ChangeEncoderAsync`** is a full pump stop/start, not an encoder swap. A swap leaves an
in-flight submit pointing at a disposed process, and that faults the loop — which ends the
broadcast, the one thing a quality step-down must never do. `StopAsync` already awaits the loop and
flushes, so this reuses the tested path and costs one short freeze, which the ladder accepts.
- **`MainViewModel.StepDown`**: one planner per broadcast, subscribed to `StatsReported`, unsubscribed on
every stop path. The pump thread only decides; the restart is posted to the dispatcher, because the
act stops the loop that raised the event.
- **The creator's choice is not rewritten**: `_encoderTierOverride` changes what the encoder emits while
the dropdown keeps showing what they picked, and the badge adds `· lowered` so the two never disagree
silently.
- Copy comes from `StepDownPlanner.Describe` (machine cause owns it, upload cause blames the upload);
the log gets the cause-tagged line for support.
Test: `EncoderRestartTests` runs a real pump with a fake encoder, changes the tier, and asserts a NEW
encoder started at the new fps/bitrate and produced a frame — the regression that would otherwise ship
as "it lowered the badge and the stream died".
Remaining for 33: shed our own capture cost before the fps step, and the session-report line.
Creator went live on the Debug build while the Release build was recording and got an empty
title/description, with the Stream Info tab filled in on screen. Both processes write to the same
profile: `BroadcastForm` is loaded ONCE at startup and each keystroke persists straight to the store,
so the instance that opened the dialog was holding the form as it was when it launched — before the
other instance saved those fields. The dialog copied from that stale copy.
`CreateGoLiveDialog` (new, extracted so it can be tested without showing a window) calls
`BroadcastForm.Load()` before composing the dialog. That is what the form's own doc comment always
claimed ("startup / Go Live refresh") but the refresh was never wired. It cannot lose an edit: every
keystroke is already persisted.
The dialog also logs `Go Live dialog: title='…' description=N chars`, so the next report of "the
dialog was blank" says immediately whether the values reached the dialog or never left the store.
Test: `BroadcastPullOutTests` writes metadata through a second `LayoutStore` handle (the other
instance) after the VM has loaded and asserts the dialog carries it. 572 green, 0 warnings.
Creator was recording on the Release build and hit "Couldn't start the audio — another copy of
LlamaCasty is already using the audio pipe" when going live on Debug. The guard did its job (no
crash), but the collision should not have been possible: the pipe name only suffixed when
`YTLIVE_INSTANCE` was set, and a Debug launched straight from the IDE has no id — so it asked for
the same `ytllive_audio` the Release build was serving.
DEBUG now always suffixes: the claimed instance id when there is one, otherwise the process id. Any
number of dev builds can run beside the Release app, and each Debug process is distinct from every
other. Release is unchanged — it resolves to the plain name, and the whole mechanism disappears in
`#if DEBUG` as before.
`TryStartAudioPipe` now logs the resolved name (`Audio pipe: …`), so the next report of this kind is
one grep instead of a code hunt.
Tests: AudioPipeInstanceTests pins that an id-less DEBUG process never resolves to the bare name;
572 green, 0 warnings.
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.
The creator's corrected Starting artwork (the in-app onboarding screen: sign in → stream details →
go live) replaces yesterday's version. 2724x1536 resampled to the 1920x1080 master, q3 (432 KB).
The previous Gemini render is archived beside the original art.
Also fixes the two reasons the replacement would not have appeared on an existing profile:
- **The first heal iterated `AllBackgrounds()`**, which returns only the LIVE scene's capture rows, so it
cleared nothing and then saved the version anyway — permanently skipping the heal. It now walks every
scene's background. Version bumped to 4 so profiles stamped 2 or 3 heal.
- **The pack URI was unqualified**, so it resolved against the ENTRY assembly: LlamaCasty.exe in
production, the test host under `dotnet test`, where the seed silently did nothing. It is now
`/LlamaCasty;component/Assets/…`, which works in both.
Test: `BackgroundDefaultArtTests` seeds a profile, plants an "old art" asset on the Starting background,
marks the layout as an older art vintage, relaunches and asserts the shipped art is re-stamped. 45
background tests pass.
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.
Reported 2026-11-06: a Release instance crashed when clicking Go Live in test mode, while a Debug
instance was recording its window. The Windows event log gave the cause:
System.IO.IOException: All pipe instances are busy.
at System.IO.Pipes.NamedPipeServerStream.Create(...)
at ytLive.Services.Audio.NamedPipeAudioWriter.Start(...)
at ytLive.Services.Audio.AudioMixer.StartLive(...)
at MainViewModel.StartStreamingSession(...)
at MainViewModel.BeginTestStream(...)
at MainViewModel.StartFromPrimaryButton(...)
at System.Windows.Controls.Button.OnClick()
Two defects, both fixed:
1. **A button click could end the process.** `StartLive` throws when the pipe name is taken, and nothing
on the go-live path caught it. `TryStartAudioPipe` now catches, logs, toasts ("Another copy of
LlamaCasty is already using the audio pipe") and rolls the session back. Recording-only takes the same
path.
2. **The pipe name was a shared constant**, so a second instance could never go live on the same machine.
`InstanceProfile.AudioPipeName` appends the dev instance id (DEBUG only); Release keeps the plain name
so the normal single-instance case is unchanged. The encoder reads the same derived name, so mixer and
ffmpeg cannot disagree.
Tests: `AudioPipeInstanceTests` — a second server on one name throws (the collision is real), dev names
derive per instance, and a writer on a taken name throws rather than silently reusing the pipe.
Debug and Release both build clean.
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.
YouTube moves the goalposts, so the app stops modelling them as its own truth and shows progress against
a threshold table that carries the date it was read.
- `Models/YppProgress.cs` — pure: three metrics, per-criterion met, and `MeetsPublishedRule`, which
encodes the real shape of the rule (subscribers AND either view route). The drawer says "x of 3 criteria
met — YouTube reviews eligibility" and spells out the either/or, so "2 of 3" can't be misread.
- `Services/YouTubeAnalyticsService.cs` — the two numbers only Analytics publishes: long-form watch hours
(trailing 12 months, `creatorContentType==video`) and Shorts-feed views (90 days, `==shorts`). No rows
means NO DATA, not zero.
- **Thresholds are data with a publication date** (`YppThresholds.AsOfUtc`, shown in the drawer) and a
test fails once that reading is more than 180 days old. The 2027-02-01 doubling (4,000h → 8,000h,
10M → 20M Shorts views) resolves from the date, not from an edit.
- **No Analytics scope → no invented numbers:** the drawer explains the missing consent instead of drawing
two empty bars as zero. Money stays behind 3·20's "Show monetary metrics" toggle.
- Fan-funding tier (500 subs) demoted to a single muted line, since the three bars are the ad-revenue path.
Tests: `YppProgressTests` — either/or eligibility, subscribers alone insufficient, Shorts as a qualifying
route, bars clamp at 100%, the doubling date, the staleness guard, Analytics parsing (no rows = no data),
and compact value formatting. FAST gate: 567 passed, 0 failed, 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 promo read 'until April 1, 2027', which is a public promise tied to a review queue outside our
control: identity verification and the tax interview are in Valve's hands (they quote up to 30 business
days), and the store page and build reviews follow. If any of that slips, the date becomes untrue.
It now reads '30 days after the store page goes live — after that $99, locked for life', in the About
box and in commercial.md, so the claim cannot be wrong however long Valve takes.
Also recorded: the $100 Steam Direct fee is PAID (creator, 2026-11-05); a store page can be configured
once identity clears. The launch-price deadline no longer depends on Valve's calendar.
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.
"I forgot the VPN" used to create a broadcast on YouTube that nothing ever pushed to: the app looked
live, YouTube held an empty broadcast, and the creator had to work out what happened. Prevention beats
recovery here, so go-live now asks one question first.
- `Services/IngestProbe.cs` — `IIngestProbe` + `TcpIngestProbe`: parse the RTMP URL, connect to the host
(rtmp → 1935, rtmps → 443) with a 2 s timeout. Any failure answers "not reachable"; the point is a
fast unambiguous answer, not a diagnosis.
- `MainViewModel.IngestPreflightAsync` runs **before the first API call** whenever a cached ingest URL
exists; on a first run it probes once the stream is resolved, still before any broadcast is created.
A false answer logs, tells the creator ("Nothing was created on YouTube…"), and rolls the session
back — nothing to clean up on YouTube.
- The probe is a test seam (`IngestProbeOverride`) like the camera and chroma ones.
Tests: `IngestPreflightTests` — unreachable aborts, reachable continues, URL parsing (rtmp/rtmps,
garbage), and the probe against **real sockets**: a listening port answers true, the same port closed
answers false and does so fast. FAST gate: 547 passed, 0 failed, 0 warnings.
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.
Derived from the clock rather than a literal, so a build shipped next year does not display a stale
date. The About test asserts the rendered string, year included.
Creator: system messages are limited to two lines; the label above the message ('STEAM ID NOT
PRESENT', 'STREAM') was repeating what the row already said and pushing the stack past its budget.
AttentionAlert loses Label; rows render Text only. The licence row is now exactly:
Steam ID Limit: 30fps
Click for More Info
(60fps with a close control once owned). Rows are identified by Id internally, so nothing in the UI
depends on the removed text. Tests updated to assert position/text rather than the heading.
A dead encoder used to run the whole stop path, so a one-second blip ended the broadcast. Now a dropped
push is relaunched against the same ingest while the broadcast is still alive.
- `Services/StreamRetryPolicy.cs` — immediate, +1 s, +2 s, +3 s. Minimum waits on purpose (creator
ruling): YouTube's grace is short, so every second not pushing is grace spent.
- `Services/StreamRecovery.cs` — the loop, with the audio pipe recreated before every attempt (its
server is single-instance and unusable after the old client dies, so a naive relaunch fails on a
missing input). After a push comes up it asks the API whether the broadcast survived: "complete"
ends recovery as `BroadcastComplete` instead of showing a live sign over a dead stream; an API
hiccup counts as recovered rather than ending a healthy session.
- `FramePump.EncoderFailed` — a dead push is recoverable; a compositor fault still goes through
`Failed` and ends the session, because retrying it would loop.
- `MainViewModel.Recovery.cs` — wires the steps, reports each episode into the left panel alert stack
(one row per episode, updated in place, log range painted), and cancels on Stop.
- Alert stack polish: a rule and a gap now separate the stack from the scene layers (they read as one
list before), and the licence indicator uses the creator's wording — `STEAM ID NOT PRESENT` /
`Steam ID Limit: 30fps` / `Click for More Info`, becoming `STEAM ID PRESENT` / `60fps` with a close
control once owned.
Tests: `StreamRecoveryTests` (schedule, recover on attempt 2 with the pipe restarted each time,
complete-broadcast honesty, unknown liveness, give-up, cancel, audio-restart fault),
`FramePumpTests` now pin that process death raises `EncoderFailed` and not `Failed`.
FAST gate: 538 passed (one documented pre-existing audio failure), 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.
Reported 2026-11-05: "when I click Loop, the video doesn't play in the preview pane". Two
causes, both real:
- `VideoClipPipe.StartAsync` bailed out once it had run once (`_run != null`), so a clip that
reached EOF could never be started again — it held its last frame forever.
- Loop is only consulted at end-of-file by a LIVE decoder, so flipping it on a finished clip
did nothing at all.
Now: the pipe reports running state and is restartable after a natural end; the manager marks a
session finished (keeping its last frame) and exposes `IsRunning`/`RestartAsync`; the layer shows
`IsMediaRunning`/`IsMediaFinished`; flipping Loop on a finished clip restarts it.
UI: `▶ Play` sits to the right of the **Video File** label and is enabled only while Loop is off
(creator ruling: with Loop on the clip already runs continuously, so there is nothing to start).
The panel says "Clip finished — holding the last frame." so a frozen picture explains itself.
Also: verify.sh no longer runs physical-input tests by default. That test moves the real cursor
(SetCursorPos + mouse_event); running it mid-gate hijacks the machine someone is using, which is
exactly how it felt. Opt in with PHYSICAL_TESTS=1 when the desktop is idle; the header documents
the scoped-run command for working hours.
Test: `MediaPlaybackRestartTests` (pipe restart, finished state, Play again, Loop-on-finished).
8 scoped tests green. FULL SUITE NOT RUN — the machine was in use; run scripts/verify.sh in a
quiet window before the next milestone.
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).
Docs: TASK 64 complete in TASKS.md, known limits recorded in the task file, HANDOFF rewritten.
verify.sh: 546 passed, 0 failed, 0 warnings.
TASK 64 slices D and E: the feature is usable end to end.
- Add a video file → one frame is probed (new `IChromaProbe`/`FfmpegChromaProbe`, one ffmpeg
pass at 160x90, off the UI thread) and the layer gets an offer: "Looks like a green screen —
Remove it", with the measured colour as a swatch.
- Accepting it turns the offer into settings (Amount / Softness / Fringe) that reach ffmpeg as
`colorkey` + `despill` + `format=bgra`, so the key is computed in the pipe and both consumers
(the shared preview bitmap and the compositor's frame) carry the same alpha.
- Media sessions are now keyed by **path + look** (`MainViewModel.MediaSessionKey`), so two
layers with the same settings still share one decoder, and changing the look releases the old
session and starts the new one. Removal, load reconciliation, loop and audio settings all move
to the same key.
- Settings persist on the `Source` row (six ALTER TABLE guards + SELECT/INSERT), so a keyed layer
comes back keyed.
- Panel section is plain creator words: Green/Blue Screen, Amount, Softness, Fringe.
Test: `ChromaKeyApplyTests` — the pipe asks ffmpeg to key (and does not when off); a green-screen
clip is offered, accepting it starts a keyed session, the layer's resolver then reads that session
rather than the old one; the setting survives a save.
Docs: TASK 64 D/E ticked with slice F (auto-apply setting + alert clips) left open; frame-pipeline
records the decode-option design; HANDOFF rewritten. verify.sh: 544 passed, 0 failed, 0 warnings.
