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 specced 'End stream -> transition(complete)' call never existed: stopping relied
entirely on enableAutoStop (viewers sat on a frozen stream-offline for ~a minute, VOD
finalized late). Found during the 2026-09-01 recording-verification pass while the
creator asked 'if there's proper close-out info yt needs, we'll provide it?'
EndBroadcastAsync POSTs liveBroadcasts/transition?broadcastStatus=complete&id=..&part=status,
called after the pump stops (RTMP EOF first) and only when a live session had a broadcast —
record-only stops stay offline. invalidTransition/410 (autoStop already ended it) is logged
and returned as an error string, never thrown: a stop must never fail over close-out.
ONE integration test (URL shape + never-throws on 403). ai.md/TASKS.md design lines marked
SHIPPED with the map-lie note.

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.

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.
