v4.7.1-fix-buffering-messages: Fix streaming buffer status messages
- Return None from transcribe_audio_stream() when buffering instead of status text - Modify WebSocket handler to only send transcription messages when result is not None - Eliminate buffering status messages appearing as transcription text - Clean streaming experience: only send actual transcription results to client 🤖 Generated with [Claude Code](https://claude.ai/code) Co-Authored-By: Claude <noreply@anthropic.com>9dffff0

CRITICAL: Implement official chunk-based processing from Colab
Complete rewrite to match official Moshi implementation: - Use streaming_forever() setup instead of context managers - Process complete audio chunks instead of individual frames - Implement proper first_frame special handling - Use official chunk splitting: chunks with exact frame_size - Apply official token extraction and decoding pattern - Version 4.1.0-chunk-based-processing This matches the exact pattern from working Colab notebook: chunks = [c for c in in_pcms.split(frame_size) if c.shape[-1] == frame_size] Should finally produce accurate transcription instead of random tokens. 🤖 Generated with [Claude Code](https://claude.ai/code) Co-Authored-By: Claude <noreply@anthropic.com>bdfd367

Use official HuggingFace documentation approach to override model detection
Peter Michael Gits +1: Claudev2.0.3 - DOCUMENTED APPROACH: Based on official HF Spaces config reference 1. Added models: [] to explicitly override automatic model detection 2. Added app_file: app.py to specify our Docker entrypoint 3. Removed unofficial .hf_config.json (not in HF docs) 4. Cleaned up .space_config.yaml to use only documented parameters 5. Per HF docs: 'Models will be parsed automatically from code if not specified' 6. Empty models: [] should prevent auto-detection of Moshi models Following official HuggingFace Spaces documentation instead of guessing! 🤖 Generated with [Claude Code](https://claude.ai/code) Co-Authored-By: Claude <noreply@anthropic.com>2a50bb0 -
Aggressive Docker enforcement - prevent HuggingFace Rust moshi-server override
Peter Michael Gits +1: Claudev2.0.2 - FORCE DOCKER MODE: HF keeps running Rust moshi-server despite config 1. Added .hf_config.json with explicit Docker enforcement 2. Added custom_headers to .space_config.yaml 3. Created .dockerignore to hide files that trigger HF auto-detection 4. Added disable_auto_inference and force_docker flags 5. Prevents: 'Starting Python frontend and official moshi-server' error Multiple approaches to force our Python Docker container! 🤖 Generated with [Claude Code](https://claude.ai/code) Co-Authored-By: Claude <noreply@anthropic.com>d4effe0 -
Fix HuggingFace configuration - force Docker mode over Rust moshi-server
Peter Michael Gits +1: Claudev2.0.1 - CRITICAL CONFIG FIX: HF was running Rust moshi-server instead of our Docker 1. Updated .space_config.yaml hardware: t4-small → l4 (was inconsistent with README) 2. Added disable_embedding: true to prevent HF auto-detection overrides 3. Ensure HuggingFace uses our custom Docker container, not built-in Rust server 4. Fixes: 'Starting Python frontend and official moshi-server' issue 5. Should now run our Python FastAPI app with full Moshi model Force Docker execution over HF defaults! 🤖 Generated with [Claude Code](https://claude.ai/code) Co-Authored-By: Claude <noreply@anthropic.com>6558d32 -
Major: Revert to full Moshi model with L4 GPU upgrade
Peter Michael Gits +1: Claudev2.0.0 - MAJOR: Back to full Moshi model with proper GPU 1. Reverted from Moshiko small model back to full Moshi (DEFAULT_REPO) 2. Upgraded HuggingFace Space hardware from t4-small to l4 (30GB VRAM) 3. Full Moshi model should fit comfortably in 30GB vs 14.74GB 4. Updated all references from Moshiko back to Moshi 5. Major version bump reflects significant architecture change 6.
