Complete rebrand to eliminate any Claude/Anthropic references: Directory Changes: - claude_rag/ → mini_rag/ (preserving git history) Content Changes: - Replaced 930+ Claude references across 40+ files - Updated all imports: from claude_rag → from mini_rag - Updated all file paths: .claude-rag → .mini-rag - Updated documentation and comments - Updated configuration files and examples Testing Changes: - All tests updated to use mini_rag imports - Integration tests verify new module structure This ensures complete independence from Claude/Anthropic branding while maintaining all functionality and git history.

Fast RAG Server with Enhanced Startup, Feedback, and Monitoring
|
|
===============================================================
|
|
|
|
Drop-in replacement for the original server with:
|
|
- Blazing fast startup with pre-loading optimization
|
|
- Real-time progress feedback during initialization
|
|
- Comprehensive health checks and status monitoring
|
|
- Enhanced error handling and recovery
|
|
- Better indexing progress reporting
|
|
- Mini-RAG-friendly status updates
