- Dify LLM integration for AI summarization
- Excel export with openpyxl
- 20 unit tests (all passing)

Client (Electron):
- Login page with company auth
- Meeting list with create/delete
- Meeting detail with real-time transcription
- Editable transcript textarea (single block, easy editing)
- AI summarization with conclusions/action items
- 5-second segment recording (efficient for long meetings)

Sidecar (Python):
- faster-whisper medium model with int8 quantization
- ONNX Runtime VAD (lightweight, ~20MB vs PyTorch ~2GB)
- Chinese punctuation processing

Change: Add Meeting Assistant MVP

Why

Enterprise users spend significant time manually documenting meetings and tracking action items. This MVP delivers an end-to-end meeting knowledge management solution with offline transcription, AI-powered summarization, and structured tracking of conclusions and action items.

What Changes

  • NEW FastAPI middleware server with MySQL integration
  • NEW Authentication proxy to company Auth API with admin role detection
  • NEW Meeting CRUD operations with metadata management
  • NEW Edge-based speech-to-text using faster-whisper (int8)
  • NEW Dify LLM integration for intelligent summarization
  • NEW Excel report generation from templates

Impact

  • Affected specs: middleware, authentication, meeting-management, transcription, ai-summarization, excel-export
  • Affected code: New Python FastAPI backend, new Electron frontend
  • External dependencies: PJ-Auth API, MySQL database, Dify LLM service

Success Criteria

  • Users can login via company SSO
  • Meetings can be created with required metadata (subject, time, chairperson, location, recorder, attendees)
  • Speech-to-text works offline on i5/8GB hardware
  • AI generates structured conclusions and action items from transcripts
  • Action items have trackable status (Open/In Progress/Done/Delayed)
  • Excel reports can be exported with all meeting data
