📝 WalkthroughWalkthroughThe STT pipeline adds macOS-gated word alignment and speaker diarization. Contracts and schemas expose speaker labels, speaker registries, and processing provenance. VAD output now prevents overlapping segments, and tests cover fallback, inference, labeling, and boundary behavior. ChangesSTT enrichment
Priority: ⬇️ Low Estimated code review effort: 3 (Moderate) | ~20 minutes Merge Risk: 🔵 Low · up to macOS transcription now conditionally returns speaker and segmentation metadata. The intended no-cluster behavior is covered in the diarization helper, but the public transcription response lacks a regression test for that shape, creating low merge-readiness risk.

In `@electron/stt/index.ts`:
- Line 424: Update the call to assignSpeakersToWords so diarization is enabled
only when actual speaker clusters are available; pass those clusters into the
assignment step. When clusters are unavailable, leave speaker metadata and
segmentation provenance absent rather than assigning every word to s1 or
returning a Pyannote/WeSpeaker identifier.
In `@electron/stt/qwenForcedAligner.ts`:
- Line 59: Update the alignment result construction around alignerUsed so Qwen
provenance is reported only after an actual forced-aligner result has been
integrated; the existing timestamp-rounding path must not be labeled as Qwen
alignment. Preserve the DTW fallback provenance and its fallback status when no
Qwen inference runs.
In `@electron/stt/sileroVad.test.ts`:
- Around line 19-21: Update the test assertions for computeVadSegments to verify
the exact padded boundaries: assert segments[0].startSec equals 0.05 and
segments[0].endSec equals 0.55, while retaining the existing single-segment
assertion.
In `@electron/stt/sileroVad.ts`:
- Line 57: Update computeVadSegments so split-branch padding cannot create
overlapping intervals: clamp each new speechStart to the previously emitted
endSec or merge overlapping segments before returning. Preserve the
non-overlapping interval contract and add a regression test covering paddingSec
larger than the silence gap.
In `@electron/stt/speakerDiarization.ts`:
- Line 39: Update assignSpeakersToWords so the single-speaker fallback keeps the
speaker registry consistent with each preserved w.sp label: create registry
entries for every label encountered, or normalize all words to s1. Add a
regression case in the speaker diarization tests covering enabled mode with a
supplied speaker label such as s2.

Do not enable diarization until speaker clusters are available.
assignSpeakersToWords always assigns every word to s1 and returns the Pyannote/WeSpeaker identifier. A multi-speaker macOS recording therefore has one false speaker label and false segmentation provenance.
Pass actual diarization clusters into this step before enabling it. Otherwise, leave speaker metadata and segmentation provenance absent.

Add an integration regression test for macOS response metadata.
Pin process.platform to "darwin" and test a transcription with no speaker clusters. Assert that result.speakers and result.provenance?.segmentation are undefined. electron/stt/index.test.ts currently has no coverage for this response shape.
