fix: treat recordings without audio as a non-error transcription state - #637
Conversation
getopenscreen#628) A screen-only recording with no system audio and no microphone was being reported as a failed transcription job (NoAudioTrackError) instead of a clean informational empty state. Changes: - classifyTranscriptionError() now matches the native NoAudioTrackError by error .name AND by the IPC-wrapped message format ("Error invoking remote method 'stt:transcribe': NoAudioTrackError: ..."), mapping both to the "no-audio" kind rather than "error" - TranscriptionStatusDot renders an amber dot (not red) for no-audio / unsupported-audio failures; tooltip shows only the human label, not the raw engine message - MediaStage detail panel uses amber (--warn) pill colour and noAudioTrackHint copy for silence failures, keeping red (--danger) only for genuinely transient errors - Tests added for native NoAudioTrackError, IPC-wrapped variant, no error-toast behaviour in the store, and amber-vs-red dot rendering Closes getopenscreen#628
📝 WalkthroughWalkthroughThe transcription pipeline now classifies missing or unsupported audio separately from transcription errors. The editor displays warning styling and a dedicated no-audio message. Tests cover native and remote error forms and both UI states. ChangesTranscription classification and editor display

Test the error.name classifier without a matching message.
The native test message contains "No decodable audio". The message pattern classifies it as "no-audio" even if the name === "NoAudioTrackError" check fails. Use a non-matching message in this test, or add a separate case.
Proposed test adjustment
- new Error("No decodable audio in /tmp/rec.mp4: Output file `#0` does not contain any stream"),
+ new Error("Native extraction failed"),📝 Committable suggestion
‼️ IMPORTANT
Carefully review the code before committing. Ensure that it accurately replaces the highlighted code, contains no missing lines, and has no issues with indentation. Thoroughly test & benchmark the code to ensure it meets the requirements.

Problem
A screen-only recording with no system audio and no microphone was recorded successfully, but opening the Transcription inspector showed
NoAudioTrackErroras a red transcription failure. The recording itself — cursor sidecar, editing flow, and export — all succeeded; this was purely a UX error-state bug.Closes #628
Root cause
classifyTranscriptionError()only matched the old renderer-side error strings ("no audio track","zero audio frames"). The native Windows WGC capture helper throws aNoAudioTrackErrorexception whose IPC-serialised form looks like:Neither the error
.namenor the"No decodable audio"substring was being matched, so the error fell through to the generic"error"bucket — rendered in red as a failed transcription job rather than the expected informational empty state.Changes
