Validation: Speaker Diarization

[ucguy4u]

Speaker Diarization Verification

Verify

• Similar voices
• Fast speaker switching
• Overlapping speech
• Unknown speakers
• Speaker rename
• Speaker merge
• Speaker persistence
• Meeting continuation

Triaged against current origin/main (732acbc6). Skipping this in the low-effort pass because the validation surface is not present yet.

Current code reality:

• the meeting slice currently carries speakerLabel through transcript entities and strict native contract parsing
• the repository tests cover typed transcript events and local meeting intelligence behavior
• I did not find implemented workflows for speaker rename, speaker merge, unknown-speaker resolution, persisted speaker identity mapping, or meeting-continuation reconciliation

Evidence in the repo:

• app/lib/features/meeting/domain/entities/transcript_chunk.dart
• app/lib/features/meeting/domain/entities/meeting_segment.dart
• app/lib/features/meeting/infrastructure/platform/native_meeting_contracts.dart
• app/test/features/meeting/native_meeting_contracts_test.dart

Why this stays open:

• most of the issue checklist is about higher-level diarization product behavior, not just payload parsing
• those behaviors need real implementation seams before a validation issue can close truthfully

Conclusion: this is too large / too incomplete for a low-effort close right now, so I am moving to the next candidate.
