+## [v9.0.1] - 2026-01-08
+
+## Bug Fixes
+
+### Claude Code 2.1.1 Compatibility
+- Fixed hook architecture for compatibility with Claude Code 2.1.0/2.1.1
+- Context is now injected silently via SessionStart hook
+- Removed deprecated `user-message-hook` (no longer used in CC 2.1.0+)
+
+### Path Validation for CLAUDE.md Distribution
+- Added `isValidPathForClaudeMd()` to reject malformed paths:
+  - Tilde paths (`~`) that Node.js doesn't expand
+  - URLs (`http://`, `https://`)
+  - Paths with spaces (likely command text or PR references)
+  - Paths with `#` (GitHub issue/PR references)
+  - Relative paths that escape project boundary
+- Cleaned up 12 invalid CLAUDE.md files created by bug artifacts
+- Updated `.gitignore` to prevent future accidents
+
+### Log-Level Audit
+- Promoted 38+ WARN messages to ERROR level for improved debugging:
+  - Parser: observation type errors, data contamination
+  - SDK/Agents: empty init responses (Gemini, OpenRouter)
+  - Worker/Queue: session recovery, auto-recovery failures
+  - Chroma: sync failures, search failures
+  - SQLite: search failures
+  - Session/Generator: failures, missing context
+  - Infrastructure: shutdown, process management failures
+
+## Internal Changes
+- Removed hardcoded fake token counts from context injection
+- Standardized Claude Code 2.1.0 note wording across documentation
