Remove cleanupOrphanedProcesses() method that was solving an old problem and is no longer needed. This method was platform-specific (crashes on Windows) and adds unnecessary complexity.
Changes:
- Delete cleanupOrphanedProcesses() method (28 lines)
- Remove call from initializeBackground()
- Worker starts cleanly without attempting process cleanup
Benefits:
- Simpler startup sequence
- Cross-platform compatibility (no pgrep/pkill)
- Reduced code complexity (YAGNI principle)
- No functional impact (orphaned processes indicate separate issues)

This completes the Windows console window fix by adding `windowsHide: true` to all remaining `execSync` calls:

- src/services/worker-service.ts:226 - pkill command for process cleanup
- src/services/worker/SDKAgent.ts:414 - where/which claude command for finding executable
These operations are less frequent than the user-prompt hook, but should still avoid spawning console windows on Windows for a complete fix.

- User documentation for <private> tag
- Technical architecture documentation
**Architecture:**
- Edge processing pattern (filter at hook, not worker)
- Defensive type handling with silentDebug
- Supports multiline, nested, and multiple tags
- Enables strategic orchestration for internal tools
**User-Facing:**
- <private> tag for manual privacy control (documented)
- Prevents sensitive data from persisting in observations
**Infrastructure:**
- <claude-mem-context> tag ready for real-time context feature
- Prevents recursive storage when context injection ships

* fix: Strip private tags from user prompts and skip memory ops for fully private prompts
Fixes critical privacy bug where <private> tags were not being stripped from
user prompts before storage in user_prompts table, making private content
searchable via mem-search.
Changes:
1. new-hook.ts: Skip memory operations for fully private prompts
- If cleaned prompt is empty after stripping tags, skip saveUserPrompt
- Skip worker init to avoid wasting resources on empty prompts
- Logs: "(fully private - skipped)"
2. save-hook.ts: Skip observations for fully private prompts
- Check if user prompt was entirely private before creating observations
- Respects user intent: fully private prompt = no observations at all
- Prevents "thoughts pop up" issue where private prompts create public observations
3. SessionStore.ts: Add getUserPrompt() method
- Retrieves prompt text by session_id and prompt_number
- Used by save-hook to check if prompt was private
4. Tests: Added 4 new tests for fully private prompt detection (16 total, all passing)
5. Docs: Updated private-tags.mdx to reflect correct behavior
- User prompts ARE now filtered before storage
- Private content never reaches database or search indices
Privacy Protection:
- Fully private prompts: No user_prompt saved, no worker init, no observations
- Partially private prompts: Tags stripped, content sanitized before storage
- Zero leaks: Private content never indexed or searchable
Addresses reviewer feedback on PR #153 about user prompt filtering.

**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)

- Combined get_context_timeline and get_timeline_by_query into a single interface for timeline exploration.
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

* refactor: Remove experimental contextualize endpoint
- Removed contextualize MCP tool from search-server (saves ~4KB)
- Disabled FTS5 fallback paths in SessionSearch (now vector-first)
- Cleaned up CLAUDE.md documentation
- Removed contextualize-rewrite-plan.md doc
Rationale:
- Contextualize is better suited as a skill (LLM-powered) than an endpoint
- Search API already provides vector search with configurable limits
- Created issue #132 to track future contextualize skill implementation
Changes:
- src/servers/search-server.ts: Removed contextualize tool definition
- src/services/sqlite/SessionSearch.ts: Disabled FTS5 fallback, added deprecation warnings
- CLAUDE.md: Cleaned up outdated skill documentation
- docs/: Removed contextualize plan document

* refactor: Complete FTS5 cleanup - remove all deprecated search code
This completes the FTS5 cleanup work by removing all commented-out
FTS5 search code while preserving database tables for backward compatibility.
Changes:
- Removed 200+ lines of commented FTS5 search code from SessionSearch.ts
- Removed deprecated degraded_search_query__when_uvx_unavailable method
- Updated all method documentation to clarify vector-first architecture
- Updated class documentation to reflect filter-only query support
- Updated CLAUDE.md to remove FTS5 search references
- Clarified that FTS5 tables exist for backward compatibility only
- Updated "Why SQLite FTS5" section to "Why Vector-First Search"
Database impact: NONE - FTS5 tables remain intact for existing installations
Search architecture:
- ChromaDB: All text-based vector search queries
- SQLite: Filter-only queries (date ranges, metadata, no query text)
- FTS5 tables: Maintained but unused (backward compatibility)

* refactor: Remove all FTS5 fallback execution code from search-server
Completes the FTS5 cleanup by removing all fallback execution paths
that attempted to use FTS5 when ChromaDB was unavailable.
Changes:
- Removed all FTS5 fallback code execution paths
- When ChromaDB fails or is unavailable, return empty results with helpful error messages
- Updated all deprecated tool descriptions (search_observations, search_sessions, search_user_prompts)
- Changed error messages to indicate FTS5 fallback has been removed
- Added installation instructions for UVX/Python when vector search is unavailable
- Updated comments from "hybrid search" to "vector-first search"
- Removed ~100 lines of dead FTS5 fallback code
Database impact: NONE - FTS5 tables remain intact (backward compatibility)
Search behavior when ChromaDB unavailable:
- Text queries: Return empty results with error explaining ChromaDB is required
- Filter-only queries (no text): Continue to work via direct SQLite
