fix: Resolve syntax error in WebSocket retry logic
Peter Michael Gits+1: Claude
34964d9
- Fixed orphaned except blocks in _connect_websocket_with_retry method
- Removed duplicate exception handling left from refactoring
- Resolves SyntaxError at line 573 causing app startup failure
- Update to v0.8.5 with critical syntax fix
The error occurred when retry logic was moved to separate method
but old exception handlers weren't properly cleaned up.

- Add sophisticated exponential backoff retry mechanism (8 attempts, 3-45s delays)
- Implement detailed timing calibration for GPU cold start pattern analysis
- Add comprehensive status code analysis (503=cold start, 403=unavailable, etc.)
- Track connection timing thresholds: <8s=warm, <30s=normal, >60s=loading issues
- Add retry attempt logging with elapsed time tracking for performance debugging
- Provide calibration summaries to identify service state patterns
- Update to v0.8.4 with enhanced WebSocket resilience
This addresses the cold start timing issues where STT services need time to warm up
and provides detailed metrics to calibrate optimal retry parameters.

feat: Add STT service preload to prevent cold start delays
Peter Michael Gits+1: Claude
628e022
- Add _preload_stt_service() method to warm up STT model during VoiceCal startup
- Call /preload?model_size=base endpoint to trigger model loading
- Prevent WebSocket HTTP 503 errors caused by cold-starting STT service
- Add timeout handling and detailed logging for preload process
- Update to v0.8.3 with STT service preload warming
Resolves the timing issue where VoiceCal tries to connect before STT service is ready.

- Fixed "multiple endpoints" error by trying specific endpoint names
- Added support for transcribe_audio endpoint name and function index
- Better error handling for different Gradio result formats
- Enhanced logging for endpoint discovery debugging
- This should fix the HTTP fallback when WebSocket fails with 403

fix: Always initialize WebSocket URLs regardless of MCP status
Peter Michael Gits+1: Claude
cdc2e76
- WebSocket URLs were only initialized when MCP failed completely
- Fake MCP success prevented WebSocket fallback initialization
- Now WebSocket/HTTP services are always initialized first
- This ensures STT WebSocket connection is always available
- Fixes "hasattr(self, 'stt_websocket_urls'): False" issue

fix: Implement correct WebSocket STT protocol and SSL handling
Peter Michael Gits+1: Claude
f7f39b9
- Add SSL context with disabled certificate verification for HF Spaces
- Implement two-step WebSocket STT protocol:
1. Wait for stt_connection_confirmed message
2. Send stt_audio_chunk message
3. Receive stt_transcription response
- Enhanced connection debugging and timeout handling
- Add test script showing WebSocket STT connection working correctly
Fixes WebSocket connectivity issues with pgits-stt-gpu-service.hf.space

feat: Remove all demo simulation code - REAL STT ONLY v0.6.0
Peter Michael Gits+1: Claude
4cf4588
MAJOR CHANGE: Complete removal of demo/simulation modes
- Remove all _simulate_stt() and _simulate_stt_with_length() methods
- Remove demo_mode flags and logic throughout MCPAudioHandler
- Force voiceCal to only use real STT services (WebSocket/MCP/HTTP)
- Return clear error messages when STT services fail instead of fake responses
- Update version to 0.6.0 for this breaking change
- No more confusing demo transcriptions that mask real issues
Real Services Only:
