 ### Recent Highlights
 
+#### v4.3.1 (2025-10-26)
+**Breaking Changes**: None (patch version)
+
+**Fixes**:
+- Fixed SessionStart hook context injection by silencing npm install output (plugin/hooks/hooks.json:25)
+- Changed npm loglevel from `--loglevel=error` to `--loglevel=silent` to ensure clean JSON output
+- Consolidated hooks architecture by removing bin/hooks wrapper layer (src/hooks/*-hook.ts)
+- Fixed double shebang issues in hook executables (esbuild now adds shebang during build)
+
+**Technical Details**:
+- Modified: plugin/hooks/hooks.json (npm install verbosity)
+- Removed: src/bin/hooks/* (wrapper layer no longer needed)
+- Consolidated: Hook logic moved directly into src/hooks/*-hook.ts files
+- Root cause: npm install stderr/stdout was polluting hook JSON output, preventing context injection
+
 #### v4.3.0 (2025-10-25)
 - Progressive Disclosure Context: Enhanced context hook with observation timeline and token cost visibility
 - Session observations now display in table format showing ID, timestamp, type indicators, title, and token counts
