1. Fix Unicode truncation panic in truncate_content: - Use char_indices() for safe multi-byte UTF-8 character handling - Add tests for emoji, CJK, and mixed Unicode content 2. Fix type inconsistency (String vs Uuid for session_id): - Change repository methods to accept &Uuid instead of &str - Update all callers to use Uuid directly - Update tests to use proper UUIDs 3. Fix silent error suppression in parsing: - Add tracing::warn() logs when turn_type/outcome parsing fails - Use and_then() instead of map().flatten() per clippy 🤖 Generated with [Claude Code](https://claude.com/claude-code) Co-Authored-By: Claude Opus 4.5 <[email protected]>
