method to fix abstraction leak and improve type safety.
Changes:
- Added getLatestUserPrompt() method to SessionStore with proper return type
- Replaced raw SQL query in SessionRoutes with type-safe method call
- Removed direct database access through dbManager.getSessionStore().db
- Improved separation of concerns (data layer vs HTTP layer)
Benefits:
- Type safety: Explicit return type instead of 'as any' cast
- Maintainability: SQL query logic belongs in data layer
- Testability: Can test query logic independently from HTTP layer
- Consistency: Follows existing pattern of query methods in SessionStore

* 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

**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)

- 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

- 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"

* fix: Reset paginated data arrays when filter changes
Critical fix for data mixing bug identified in PR review follow-up.
Problem:
When filter changes, usePagination correctly resets its offset to 0, but
the paginated state arrays (observations, summaries, prompts) were NOT
being reset. This caused data from different projects to mix together
because setState appends to the existing array.
Example:
- User views Project A: [A1, A2, A3]
- User switches to Project B
- API fetches [B1, B2, B3]
- setState does: [...prev, ...new] = [A1, A2, A3, B1, B2, B3] ❌
Solution:
Added a separate useEffect that resets all three paginated arrays when
currentFilter changes. This happens BEFORE handleLoadMore fetches new
data, ensuring clean state for the new filter.
Files changed:
- src/ui/viewer/App.tsx: Added useEffect to reset arrays on filter change
- plugin/ui/viewer-bundle.js: Built UI bundle
Testing:
1. Select Project A, verify data loads
2. Switch to Project B
3. Verify ONLY Project B data is shown (no mixing)
4. Switch back to "All Projects"
5. Verify all data appears correctly

* refactor: Combine filter change useEffect hooks for guaranteed order
Merged two separate useEffect hooks into one to:
1. Guarantee execution order (reset THEN load)
2. Reduce complexity (one hook instead of two)
3. Make intent clearer with single comment
Before:
- useEffect #1: handleLoadMore() on filter change
- useEffect #2: Reset arrays on filter change
- React could run these in any order
After:
- Single useEffect: Reset arrays THEN handleLoadMore()
- Execution order is now guaranteed
