**Problem:**
- Summaries created with empty project names even after database fix
- 13 summaries had empty project, couldn't appear in context-hook
- In-memory sessions cached stale empty project value
**Root Cause:**
SessionManager caches ActiveSession objects in memory. When reusing
an existing session, it never refreshed the project field from the
database. Even though createSDKSession() now updates the DB with the
correct project, the in-memory session.project remained empty, causing
summaries to be stored with empty project.
**Flow:**
1. Session created with empty project (cached in memory)
2. new-hook UPDATE fixes project in database
3. SessionManager reuses cached session (stale project="")
4. Summary stored with session.project (empty)
5. Context-hook can't find summary (WHERE project = 'claude-mem')
**Solution:**
When SessionManager.initializeSession() reuses an existing session,
refresh the project field from the database. This ensures summaries
and observations always use the latest project value.
**Impact:**
- Future summaries will have correct project name
- Backfilled 13 historical summaries with project='claude-mem'
- Context injection will now show recent summaries
- Both observations AND summaries fixed

**Problem:**
- Sessions created with empty project names couldn't be updated
- INSERT OR IGNORE skipped updates when session already existed
- Context-hook couldn't find observations (WHERE project = 'claude-mem')
- 364 observations had empty project names
**Root Cause:**
createSDKSession() used INSERT OR IGNORE for idempotency, but never
updated project/prompt fields when session already existed. If SAVE hook
created session first (with empty project), NEW hook couldn't fix it.
**Solution:**
When INSERT is ignored (session exists), UPDATE project and user_prompt
if we have non-empty values. This ensures project name gets set even
when session was created by SAVE hook or with incomplete data.
**Impact:**
- New sessions will always have correct project name
- Backfilled 364 historical observations with project='claude-mem'
- Context injection will now work (finds observations by project)

- Each test result file captures specific search failures or outcomes, including issues with undefined properties and successful execution of search queries.
- Enhanced documentation of search architecture and testing strategies, ensuring compliance with established guidelines and improving overall search functionality.
* feat: Enhance unified search API with catch-all parameters and backward compatibility
- Implemented a unified search API at /api/search that accepts catch-all parameters for filtering by type, observation type, concepts, and files.
- Maintained backward compatibility by keeping granular endpoints functional while routing through the same infrastructure.
- Completed comprehensive testing of search capabilities with real-world query scenarios.
fix: Address missing debug output in search API query tests
- Flushed PM2 logs and executed search queries to verify functionality.
- Diagnosed absence of "Raw Chroma" debug messages in worker logs, indicating potential issues with logging or query processing.
refactor: Improve build and deployment pipeline for claude-mem plugin
- Successfully built and synced all hooks and services to the marketplace directory.
- Ensured all dependencies are installed and up-to-date in the deployment location.
feat: Implement hybrid search filters with 90-day recency window
- Enhanced search server to apply a 90-day recency filter to Chroma results before categorizing by document type.
fix: Correct parameter handling in searchUserPrompts method
- Added support for filter-only queries and improved dual-path logic for clarity.
refactor: Rename FTS5 method to clarify fallback status
- Renamed escapeFTS5 to escapeFTS5_fallback_when_chroma_unavailable to indicate its temporary usage.
feat: Introduce contextualize tool for comprehensive project overview
- Added a new tool to fetch recent observations, sessions, and user prompts, providing a quick project overview.

feat: Unified search tool added to MCP server
- New tool queries all memory types simultaneously, providing combined chronological results for improved search efficiency.
* Refactor search functionality to clarify FTS5 fallback usage
- Updated `worker-service.cjs` to replace FTS5 fallback function with a more descriptive name and improved error handling.
- Enhanced documentation in `SKILL.md` to specify the unified API endpoint and clarify the behavior of the search engine, including the conditions under which FTS5 is used.
- Modified `search-server.ts` to provide clearer logging and descriptions regarding the fallback to FTS5 when UVX/Python is unavailable.
- Renamed and updated the `SessionSearch.ts` methods to reflect the conditions for using FTS5, emphasizing the lack of semantic understanding in fallback scenarios.
* feat: Add ID-based fetch endpoints and simplify mem-search skill
**Problem:**
- Search returns IDs but no way to fetch by ID
- Skill documentation was bloated with too many options
- Claude wasn't using IDs because we didn't tell it how
**Solution:**
1. Added three new HTTP endpoints:
- GET /api/observation/:id
- GET /api/session/:id
- GET /api/prompt/:id
2. Completely rewrote SKILL.md:
- Stripped complexity down to essentials
- Clear 3-step prescriptive workflow: Search → Review IDs → Fetch by ID
- Emphasized ID usage: "The IDs are there for a reason - USE THEM"
- Removed confusing multi-endpoint documentation
- Kept only unified search with filters
**Impact:**
- Token efficiency: Claude can now fetch full details only for relevant IDs
- Clarity: One clear workflow instead of 10+ options to choose from
- Usability: IDs are no longer wasted context - they're actionable

* fix: Use dynamic project name detection instead of hardcoded values
Fixes#140
Previously, the worker process used hardcoded "claude-mem" for:
- ChromaSync instantiation in DatabaseManager
- ChromaDB collection naming in search-server
This caused all observations to be tagged with "claude-mem" regardless
of the actual project being worked on.
Now both services use getCurrentProjectName() to dynamically detect the
project based on the worker's current working directory.

Critical hotfix for PM2 worker startup issue. The worker now correctly

Co-Authored-By: Claude <noreply@anthropic.com>
- Updated `new-hook.js` and `save-hook.js` to enhance logging functionality, including better error messages and structured logging.
- Improved the handling of worker startup in `summary-hook.js` and `worker-utils.ts`, ensuring proper directory context for PM2.
- Added checks for worker health and streamlined session management across hooks.
- Added a new script to simulate token savings from Endless Mode using real observation data.
- Introduced functions to calculate token costs with and without Endless Mode, showcasing the differences in context handling.
- Enhanced output to display detailed token usage statistics and potential savings at scale.
- Integrated assumptions for user activity to estimate weekly and annual token savings.
- Updated worker-utils to automatically start the worker using PM2 if not running, improving service reliability.
Root cause: The ensureDiscoveryTokensColumn migration was using version 7,
which was already taken by removeSessionSummariesUniqueConstraint. This
duplicate version number caused migration tracking issues in some databases.
Changes:
- Updated migration version from 7 to 11 (next available)
- Added schema_versions check to prevent unnecessary re-runs
- Updated comments to clarify the version number conflict
- Added error propagation (already present, but now more reliable)
This resolves issue #121 where users were seeing "no such column: discovery_tokens"
errors after upgrading to v6.0.6.
Affected users can manually add the columns:
ALTER TABLE observations ADD COLUMN discovery_tokens INTEGER DEFAULT 0;
ALTER TABLE session_summaries ADD COLUMN discovery_tokens INTEGER DEFAULT 0;
Or wait for v6.0.7 release which includes this fix.
