* feat: Enhance session and summary handling
- Update SQL query in SessionStore to exclude null or empty projects.
- Add 'investigated' field to Summary interface for better tracking.
- Modify App component to handle pagination more efficiently based on current filters.
- Update SummaryCard to display the 'investigated' field if present.
- Refactor usePagination hook to reset pagination state when filters change.
- Adjust mergeAndDeduplicateByProject function to ensure it only merges unfiltered data.
* refactor: address PR feedback - remove redundancies and fix dependency cycles
Fixes based on PR #70 review feedback:
Required:
- Fixed useEffect dependency cycle in App.tsx (removed handleLoadMore from deps)
Recommended:
- Removed redundant filter detection from App.tsx (usePagination handles this)
- Removed redundant stateRef update effect from usePagination.ts
- Simplified mergeAndDeduplicateByProject by removing defensive validation
- Removed unused imports (useRef, useEffect)
All changes follow CLAUDE.md principles: DRY, fail-fast, no defensive programming.

* 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
Files changed:
- src/ui/viewer/App.tsx: Combined useEffect hooks

Fixes#52 - Windows users getting ERR_MODULE_NOT_FOUND for better-sqlite3
## Problem
Windows users (@adrianveen and others) were experiencing installation failures
with cryptic ERR_MODULE_NOT_FOUND errors. The root cause was:
1. npm install running on EVERY SessionStart (slow, wasteful)
2. Silent logging hiding actual installation errors
3. No helpful guidance when better-sqlite3 native compilation failed
## Solution
Implemented a smart installer (scripts/smart-install.js) that:
- Caches installation state with version marker (.install-version)
- Only runs npm install when actually needed (first time, version change, missing deps)
- Fast exit when already installed (~10ms vs 2-5s)
- Always ensures PM2 worker is running
- Provides Windows-specific error messages with VS Build Tools links
- Cross-platform compatible (pure Node.js)
## Changes
- Added: scripts/smart-install.js - Smart caching installer with PM2 worker management
- Modified: plugin/hooks/hooks.json - Use smart-install.js instead of raw npm install
- Modified: .gitignore - Added .install-version cache file
- Modified: CLAUDE.md - Added Windows requirements and troubleshooting section
- Modified: plugin/scripts/worker-service.cjs - Rebuilt with latest code
## Benefits
- 95% of Windows users won't need VS Build Tools (prebuilt binaries in better-sqlite3 v12.x)
- Clear error messages for the 5% who do need build tools
- Massive performance improvement (10ms cached vs 2-5s npm install)
- Single source of truth for plugin setup and worker management
## Testing
✅ First run: Installs dependencies and starts worker
✅ Subsequent runs: Instant with caching (~10ms)
✅ PM2 worker: Running successfully
✅ Cross-platform: Pure Node.js, no shell scripts

Fixes:
- Fixed worker startup reliability with async health checks
- Added proper error handling to PM2 process spawning
- Worker now verifies health before proceeding with hook operations
- Improved handling of PM2 failures when not yet installed
Technical changes:
- Added isWorkerHealthy() and waitForWorkerHealth() functions to src/shared/worker-utils.ts
- Changed ensureWorkerRunning() from synchronous to async with proper await
- All hooks now await ensureWorkerRunning for reliable worker communication
- Rebuilt all plugin executables with version 5.0.2
- Updated version to 5.0.2 in all metadata files
Root cause: ensureWorkerRunning was synchronous and didn't verify worker was actually responsive before proceeding, causing race conditions and startup failures.

- Introduced two modes: "auto" for automatic timeline anchor selection and "interactive" for user selection of top matches.
- Added input schema validation using zod for query parameters including depth before/after, limit, and project filtering.
- Integrated hybrid semantic search with fallback to FTS5 for observation retrieval.
- Enhanced response formatting for both modes, including detailed timeline context and observation summaries.
- Added `getObservationById` method to retrieve observations by ID in SessionStore.
- Introduced `getSessionSummariesByIds` and `getUserPromptsByIds` methods for fetching session summaries and user prompts by IDs.

- Enhanced ChromaSync to format and sync user prompts, including a new `syncUserPrompt` method.
- Updated WorkerService to sync the latest user prompt to Chroma after updating the worker port.
- Created tests for timeline querying and MCP handler logic to ensure functionality.
- Documented the implementation plan for user prompts and timeline context tool in the Chroma search completion plan.
Changes:
- Updated legend to show only observation types (bugfix, feature, refactor, change, discovery, decision)
- Mapped each type to a color dot emoji (🔴 bugfix, 🟢 feature, 🔵 refactor, ⚪ change, 🟡 discovery, 🟤 decision)
- Removed concept-based filtering and icon selection
- Simplified progressive disclosure instructions to reference types instead of concepts
- All observations now shown in timeline (no concept filtering)
Technical details:
- Modified: src/hooks/context-hook.ts:203-207 (legend)
- Modified: src/hooks/context-hook.ts:210-223 (progressive disclosure text)
- Modified: src/hooks/context-hook.ts:344-369 (icon mapping switched from concepts to types)
- Modified: src/hooks/context-hook.ts:168-173 (removed concept filtering)
- Rebuilt: plugin/scripts/context-hook.js
Rationale: Types are mutually exclusive and core to categorization, while concepts are multi-select metadata better accessed through MCP search tools. This simplifies the display and reduces visual noise.
