Improved code formatting, line breaks, and indentation across chunking logic and multiple test modules to enhance code clarity and maintain consistent style. No functional changes made.
- Refactored database batch operations to ensure transaction atomicity and simplify nested structure.
- Added `Makefile` for `knowledge-base` and `llm-gateway` modules to streamline development workflows.
- Simplified `Dockerfile` for `llm-gateway` by removing multi-stage builds and optimizing dependencies.
- Improved code readability in `collection_manager` and `failover` modules with refined logic.
- Minor fixes in `test_server` and Redis health check handling for better diagnostics.
Security fixes from deep review:
- Add input validation patterns for project_id, agent_id, collection
- Add path traversal protection for source_path (reject .., null bytes)
- Add error codes (INTERNAL_ERROR) to generic exception handlers
- Handle FieldInfo objects in validation for test robustness
Performance fixes:
- Enable concurrent hybrid search with asyncio.gather
Health endpoint improvements:
- Check all dependencies (database, Redis, LLM Gateway)
- Return degraded/unhealthy status based on dependency health
- Updated tests for new health check response structure
All 139 tests pass.
