Critical Bugfix:
- Fixed overly defensive observation validation blocking observations from being saved
- Parser now NEVER skips observations - always saves them
- Invalid or missing type defaults to "change" (generic catch-all type)
- Removed validation requiring title, subtitle, and narrative fields
- Prevents critical data loss - partial observations better than no observations
Impact:
- Before: Missing title, subtitle, OR narrative caused entire observation to be discarded
- After: ALL observations preserved regardless of field completeness
- Even partial observations contain valuable data: concepts, files_read, files_modified, facts
- LLMs make mistakes - system must be resilient and save everything
- Consistent with v4.2.5 summary fix
Technical changes:
- Updated src/sdk/parser.ts:52-67 to never skip observations
- Uses "change" as fallback type for invalid/missing types (no schema change)
- Updated ParsedObservation interface to allow null for title, subtitle, narrative
- Updated SessionStore.storeObservation signature to accept nullable fields
- Updated built worker-service.cjs
- Bumped version to 4.2.6 in all metadata files

- Updated contextHook to query session_summaries directly instead of using sdk_sessions table.
- Removed unnecessary complexity in output formatting, focusing on recent summaries for the project.
- Enhanced file reading and modification tracking by parsing observations directly.
- Made the database connection public in SessionStore for easier access.
- Added functionality to automatically create a session record in the database if it does not exist when storing observations or session summaries.
- Updated `storeObservation` and `storeSummary` methods to include checks for existing session records and insert new records as needed.
- Added logging for auto-created session records for better traceability.
- Added functionality to save raw user prompts for full-text search in the newHook function.
- Introduced new search endpoint 'search_user_prompts' to retrieve user prompts using FTS5.
- Created UserPromptRow and UserPromptSearchResult types for handling user prompt data.
- Implemented searchUserPrompts method in SessionSearch class to perform FTS5 queries.
- Created user_prompts table with FTS5 support and necessary triggers for data synchronization.
- Updated SessionStore to include methods for saving user prompts and managing the new table.
Root cause: Hooks provide session_id as the source of truth. We were adding
unnecessary validation (checking if sessions exist, checking status, etc.)
which caused 409 conflicts when continuing sessions after /exit.
Changes:
1. worker-service.ts: Removed 409 "Session already exists" check in handleInit
2. SessionStore.ts: Made createSDKSession idempotent using INSERT OR IGNORE
3. new-hook.ts: Simplified to just call createSDKSession - no findActiveSDKSession,
no reactivateSession logic, no status management
4. save-hook.ts: Removed session validation, use fixed port instead of session.worker_port
5. summary-hook.ts: Removed session validation, use fixed port instead of session.worker_port
Philosophy: Hooks manage lifecycle, we just save data with whatever session_id
they give us. No validation, no status checks, no guessing.

- Deleted the advanced_search tool from the search-server.ts file, which combined full-text search with structured filters for observations and sessions.
- Removed the advancedSearch method from the SessionSearch class, which handled the logic for performing advanced searches using FTS5 and structured filters.
- Filter out observation type from concepts array in parseObservations function to ensure types and concepts are treated as separate dimensions. Added logging for removed types.
- Update prompts documentation to clarify that the observation type must not be included in the concepts array.
- Modify search-server to provide clearer guidance on result limits, emphasizing starting with smaller limits to avoid exceeding token limits.
- Refactor SessionSearch methods to accept options for limit, offset, and orderBy parameters, improving flexibility in querying observations by concept and type.
- Updated contextHook to support colorized output for terminal and JSON format for hooks.
- Introduced ANSI color codes for improved readability in terminal output.
- Modified the output structure to include session details with color formatting.
- Added a new method in SessionStore to aggregate files read and modified from observations for a session.
- Improved error handling for JSON parsing of file data in the new method.
Fixed better-sqlite3 distribution by implementing self-bootstrapping hooks
that auto-install dependencies on first run. This eliminates the need for
users to have native compilation tools or manually install dependencies.
## Solution
Instead of bundling 25MB of better-sqlite3 binaries in git or requiring
manual npm install, hooks now bootstrap themselves on first execution:
1. Created `src/shared/bootstrap.ts` with `ensureDependencies()` function
2. Added bootstrap calls to all hook entry points (context, new, save, summary, cleanup)
3. Created `plugin/scripts/package.json` declaring better-sqlite3 dependency
4. Bootstrap checks if `node_modules` exists, runs `npm install` if missing
5. npm automatically downloads prebuilt better-sqlite3 binary for user's platform
## Changes
**Core Bootstrap System:**
- Added src/shared/bootstrap.ts: Auto-install dependencies using npm
- Modified all hooks (context, new, save, summary, cleanup) to call ensureDependencies()
- Created plugin/scripts/package.json with better-sqlite3 dependency
**Build & Distribution:**
- Removed node_modules copying logic from build script
- Build output is now compact (hooks + package.json, no binaries)
- Updated marketplace.json to point to GitHub for direct installation
**Documentation:**
- Updated README: GitHub Marketplace installation is now recommended method
- Installation instructions emphasize no compilation needed
- Version bumped to 4.0.5 throughout
## Benefits
- ✅ No git bloat (repo stays small, no 25MB binaries committed)
- ✅ No compilation needed (npm downloads prebuilt binaries)
- ✅ Works on all platforms (npm handles platform-specific binaries)
- ✅ Zero manual steps (hooks bootstrap themselves automatically)
- ✅ Idempotent (skips install if dependencies already exist)
Installation now works via simple:
```
/plugin marketplace add https://github.com/thedotmack/claude-mem
/plugin install claude-mem
```
