+## [6.2.1] - 2025-11-23
+
+## 🐛 Bug Fixes
+
+### Critical: Empty Project Names Breaking Context Injection
+
+**Problem:**
+- Observations and summaries created with empty project names
+- Context-hook couldn't find recent context (queries `WHERE project = 'claude-mem'`)
+- Users saw no observations or summaries in SessionStart since Nov 22
+
+**Root Causes:**
+
+1. **Sessions:** `createSDKSession()` used `INSERT OR IGNORE` for idempotency, but never updated project field when session already existed
+2. **In-Memory Cache:** `SessionManager` cached sessions with stale empty project values, even after database was updated
+
+**Fixes:**
+
+- `5d23c60` - fix: Update project name when session already exists in createSDKSession
+- `54ef149` - fix: Refresh in-memory session project when updated in database
+
+**Impact:**
+- ✅ 364 observations backfilled with correct project names
+- ✅ 13 summaries backfilled with correct project names  
+- ✅ Context injection now works (shows recent observations and summaries)
+- ✅ Future sessions will always have correct project names
+
+## 📦 Full Changelog
+
+**Commits since v6.2.0:**
+- `634033b` - chore: Bump version to 6.2.1
+- `54ef149` - fix: Refresh in-memory session project when updated in database
+- `5d23c60` - fix: Update project name when session already exists in createSDKSession
+
+## [6.2.0] - 2025-11-22
+
+## Major Features
+
+### Unified Search API (#145, #133)
+- **Vector-first search architecture**: All text queries now use ChromaDB semantic search
+- **Unified /api/search endpoint**: Single endpoint with filter parameters (type, concepts, files)
+- **ID-based fetch endpoints**: New GET /api/observation/:id, /api/session/:id, /api/prompt/:id
+- **90-day recency filter**: Automatic relevance filtering for search results
+- **Backward compatibility**: Legacy endpoints still functional, routing through unified infrastructure
+
+### Search Architecture Cleanup
+- **Removed FTS5 fallback code**: Eliminated ~300 lines of deprecated full-text search code
+- **Removed experimental contextualize endpoint**: Will be reimplemented as LLM-powered skill (see #132)
+- **Simplified mem-search skill**: Streamlined to prescriptive 3-step workflow (Search → Review IDs → Fetch by ID)
+- **Better error messages**: Clear guidance when ChromaDB/UVX unavailable
+
+## Bug Fixes
+
+### Search Improvements
+- Fixed parameter handling in searchUserPrompts method
+- Improved dual-path logic for filter-only vs text queries
+- Corrected missing debug output in search API

+
+## [6.1.0] - 2025-11-19
+
+## Viewer UI: Responsive Layout Improvements
+
+The viewer UI now handles narrow screens better with responsive breakpoints:
+
+- Community button relocates to sidebar below 600px width
+- Projects dropdown relocates to sidebar below 480px width
+- Sidebar constrained to 400px max width
+
+Makes the viewer usable on phones and narrow browser windows.
+
+## [6.0.9] - 2025-11-17
+
+## Queue Depth Indicator Feature
+
+Added a real-time queue depth indicator to the viewer UI that displays the count of active work items (queued + currently processing).
+
+### Features
+- Visual badge next to claude-mem logo
+- Shows count of pending messages + active SDK generators
+- Only displays when queueDepth > 0
+- Subtle pulse animation for visual feedback
+- Theme-aware styling
+- Real-time updates via SSE
+
+### Implementation
+- Backend: Added `getTotalActiveWork()` method to SessionManager
+- Backend: Updated worker-service to broadcast queueDepth via SSE
+- Frontend: Enhanced Header component to display queue bubble
+- Frontend: Updated useSSE hook to track queueDepth state
+- Frontend: Added CSS styling with pulse animation
+
+### Closes
+- #122 - Implement queue depth indicator feature
+- #96 - Add real-time queue depth indicator to viewer UI
+- #97 - Fix inconsistent queue depth calculation
+
+### Credit
+Original implementation by @thedotmack in PR #96
+Bug fix by @copilot-swe-agent in PR #97
+
+## [6.0.8] - 2025-11-17
+
+## Critical Fix
+
+This patch release fixes a critical bug where the PM2 worker process would start from the wrong directory (development folder instead of marketplace folder), causing the plugin to malfunction when installed via the marketplace.
+
+### What's Fixed
+
+- **Worker Startup Path Resolution** (`src/shared/worker-utils.ts:61`)  
+  Added `cwd: pluginRoot` option to `execSync` when starting PM2
+  
+  This ensures the worker always starts from the correct marketplace directory (`~/.claude/plugins/marketplaces/thedotmack/`), regardless of where the hook is invoked from.
+
+### Impact
+
+Users will no longer experience issues with the worker starting from the wrong location. The plugin now works correctly when installed via marketplace without manual intervention.
+
+### Verification
+
+Run `pm2 info claude-mem-worker` to verify:
+- **exec cwd** should be: `/Users/[username]/.claude/plugins/marketplaces/thedotmack`
+- **script path** should be: `/Users/[username]/.claude/plugins/marketplaces/thedotmack/plugin/scripts/worker-service.cjs`
+
+## [6.0.7] - 2025-11-17
+
+## Critical Hotfix: Database Migration Issue (#121)
+
+This is an emergency hotfix addressing a critical database migration bug that prevented claude-mem from loading for some users.
+
+### What was fixed
+
+**Issue**: Users were seeing `SqliteError: no such column: discovery_tokens` when starting Claude Code.
+
+**Root Cause**: The `ensureDiscoveryTokensColumn` migration was using version number 7, which was already taken by another migration (`removeSessionSummariesUniqueConstraint`). This duplicate version number caused migration tracking issues in databases that were upgraded through multiple versions.
+
+**Fix**: 
+- Changed migration version from 7 to 11 (next available)
+- Added explicit schema_versions check to prevent unnecessary re-runs
+- Improved error propagation and documentation
+
+### Upgrade Instructions
+
+**If you're experiencing the error:**
+
+Option 1 - Manual fix (preserves history):
+```bash
+sqlite3 ~/.claude-mem/claude-mem.db "ALTER TABLE observations ADD COLUMN discovery_tokens INTEGER DEFAULT 0; ALTER TABLE session_summaries ADD COLUMN discovery_tokens INTEGER DEFAULT 0;"
+```
+
+Option 2 - Delete and recreate (loses history):
+```bash
+rm ~/.claude-mem/claude-mem.db
+# Restart Claude Code - database will recreate with correct schema
+```
+
+Option 3 - Fresh install:
+Just upgrade to v6.0.7 and the migration will work correctly.
+
+### Changes
+
+- **Fixed**: Database migration version conflict (migration 7 → 11) (#121)
+- **Improved**: Migration error handling and schema_versions tracking
+
+### Full Changelog
+
+See [CHANGELOG.md](https://github.com/thedotmack/claude-mem/blob/main/CHANGELOG.md) for complete version history.

+
+**Affected Users**: @liadtigloo @notmyself - this release fixes your reported issue. Please try one of the upgrade options above and let me know if the issue persists.
+
+Thanks to everyone who reported this issue with detailed error logs! 🙏
+
+## [6.0.6] - 2025-11-17
+
+## Critical Bugfix Release
+
+### Fixed
+- **Database Migration**: Fixed critical bug where `discovery_tokens` migration logic trusted `schema_versions` table without verifying actual column existence (#121)
+- Migration now always checks if columns exist before queries, preventing "no such column" errors
+- Safe for all users - auto-migrates on next Claude Code session without data loss
+
+### Technical Details
+- Removed early return based on `schema_versions` check that could skip actual column verification
+- Migration now uses `PRAGMA table_info()` to verify column existence before every query
+- Ensures idempotent, safe schema migrations for SQLite databases
+
+### Impact
+- Users experiencing "SqliteError: no such column: discovery_tokens" will be automatically fixed
+- No manual intervention or database backup required
+- Update to v6.0.6 via marketplace or `git pull` and restart Claude Code
+
+**Affected Users**: All users who upgraded to v6.0.5 and experienced the migration error
+
+## [6.0.5] - 2025-11-17
+
+## Changes
+
+### Automatic MCP Server Cleanup
+- Automatic cleanup of orphaned MCP server processes on worker startup
+- Self-healing maintenance runs on every worker restart
+- Prevents orphaned process accumulation and resource leaks
+
+### Improvements
+- Removed manual cleanup notice from session context
+- Streamlined worker initialization process
+
+## What's Fixed
+- Memory leaks from orphaned uvx/python processes are now prevented automatically
+- Workers self-heal on every restart without manual intervention
+
+---
+
+**Release Date**: November 16, 2025
+**Plugin Version**: 6.0.5
+
+## [6.0.4] - 2025-11-17
+
+**Patch Release**

 # Claude-Mem: AI Development Instructions
 
 ## What This Project Is
 
 Claude-mem is a Claude Code plugin providing persistent memory across sessions. It captures tool usage, compresses observations using the Claude Agent SDK, and injects relevant context into future sessions.
 
-**Your Role**: You are working on the plugin itself. When users interact with Claude Code with this plugin installed, your observations get captured and become their persistent memory.
+**Current Version**: 6.3.0
 
-**Current Version**: 6.0.4
+## Architecture
 
-## IMPORTANT: Skills Are Auto-Invoked
+**5 Lifecycle Hooks**: SessionStart → UserPromptSubmit → PostToolUse → Summary → SessionEnd
 
-**There is no `/skill` command.** Skills auto-invoke based on description metadata matching user queries. Don't document manual invocation (e.g., "Run `/skill troubleshoot`"). Instead: "The troubleshoot skill auto-activates when issues are detected."
+**Hooks** (`src/hooks/*.ts`) - TypeScript → ESM, built to `plugin/scripts/*-hook.js`
 
-## Critical Architecture Knowledge
+**Worker Service** (`src/services/worker-service.ts`) - Express API on port 37777, PM2-managed, handles AI processing asynchronously
 
-### The Lifecycle Flow
+**Database** (`src/services/sqlite/`) - SQLite3 at `~/.claude-mem/claude-mem.db` with FTS5 full-text search
 
-1. **SessionStart** → smart-install.js runs first (pre-hook), then `context-hook.ts` runs
-   - Smart installer checks dependencies (cached, only runs on version changes)
-   - Starts PM2 worker if not healthy
-   - Injects context from previous sessions (configurable observation count)
+**Search Skill** (`plugin/skills/mem-search/SKILL.md`) - HTTP API for searching past work, auto-invoked when users ask about history
 
-2. **UserPromptSubmit** → `new-hook.ts` runs
-   - Creates session record in SQLite
-   - Saves raw user prompt for FTS5 search
+**Chroma** (`src/services/sync/ChromaSync.ts`) - Vector embeddings for semantic search
 
-3. **PostToolUse** → `save-hook.ts` runs
-   - Captures your tool executions
-   - Sends to worker service for AI compression
+**Viewer UI** (`src/ui/viewer/`) - React interface at http://localhost:37777, built to `plugin/ui/viewer.html`
 
-4. **Summary** → Summary hook generates session summaries
+## Build Commands
 
-5. **SessionEnd** → `cleanup-hook.ts` runs
-   - Marks session complete (graceful, not DELETE)
-   - Skips on `/clear` to preserve ongoing sessions
+**Hooks only**: `npm run build && npm run sync-marketplace`
 
-**Note**: smart-install.js is a pre-hook script (not a lifecycle hook). It's called before context-hook via command chaining in hooks.json and only runs when dependencies need updating.
+**Worker changes**: `npm run build && npm run sync-marketplace && npm run worker:restart`
 
-### Key Components
+**Skills only**: `npm run sync-marketplace`
 
-**Hooks** (`src/hooks/*.ts`)
-- Built to `plugin/scripts/*-hook.js` (ESM format)
-- Must output valid JSON to `hookSpecificOutput` field
-- Called by Claude Code lifecycle events
-
-**Worker Service** (`src/services/worker-service.ts`)
-- Express.js API on port 37777 (configurable via `CLAUDE_MEM_WORKER_PORT`)
-- Managed by PM2 (auto-started by hooks)
-- Built to `plugin/worker-service.cjs` (CJS format)
-- Handles AI processing asynchronously to avoid hook timeouts
-
-**Database** (`src/services/sqlite/`)
-- SQLite3 with better-sqlite3 (NOT bun:sqlite - that's legacy)
-- Location: `~/.claude-mem/claude-mem.db`
-- FTS5 virtual tables for full-text search
-- `SessionStore` = CRUD, `SessionSearch` = FTS5 queries
-
-**Search Skill** (`plugin/skills/mem-search/SKILL.md`)
-- Provides access to all search functionality via HTTP API + skill
-- Auto-invoked when users ask about past work, decisions, or history
-- Uses HTTP endpoints instead of MCP tools (~2,250 token savings per session)
-- 10 search operations: observations, sessions, prompts, by-type, by-file, by-concept, timelines, etc.
-
-**Chroma Vector Database** (`src/services/sync/ChromaSync.ts`)
-- Hybrid semantic + keyword search architecture
-- Automatic vector embedding synchronization
-- 90-day recency filtering for relevant results
-- Combined with SQLite FTS5 for optimal search performance
-
-**Viewer UI** (`src/ui/viewer/`)
-- React + TypeScript web interface accessible at http://localhost:37777
-- Real-time memory stream visualization via Server-Sent Events (SSE)
-- Infinite scroll pagination for observations, sessions, and user prompts
-- Project filtering and settings persistence
-- Built to `plugin/ui/viewer.html` (self-contained bundle via esbuild)
-- Auto-reconnection and error recovery
-
-## How to Make Changes
-
-### When You Modify Hooks
-```bash
-npm run build
-npm run sync-marketplace
-```
-Changes take effect on next Claude Code session. No worker restart needed.
-
-### When You Modify Worker Service
-```bash
-npm run build
-npm run sync-marketplace
-npm run worker:restart
-```
-Must restart PM2 worker for changes to take effect.
-
-### When You Modify Search Skill
-```bash
-npm run sync-marketplace
-```
-Skill changes take effect immediately on next Claude Code session. No build or restart needed (skills are markdown).
-
-### When You Modify Viewer UI
-```bash
-npm run build
-npm run sync-marketplace
-npm run worker:restart
-```
-Changes to React components, styles, or viewer logic require rebuilding and restarting the worker. Refresh browser to see changes.
-
-### Build Pipeline
-1. `npm run build` → Compiles TypeScript, outputs to `plugin/`
-2. `npm run sync-marketplace` → Syncs to `~/.claude/plugins/marketplaces/thedotmack/`
-3. Changes are live for next session (hooks/skills) or after restart (worker)
-
-## Coding Standards
-
-**Philosophy**: Write the dumb, obvious thing first. Add complexity only when you hit the problem.
-
-**Key Principles:**
-1. **YAGNI**: Don't build it until you need it
-2. **DRY**: Extract patterns after second duplication, not before
-3. **Fail Fast**: Explicit errors beat silent failures
-4. **Simple First**: Write the obvious solution, optimize only if needed
-5. **Delete Aggressively**: Less code = fewer bugs
-
-**Common anti-patterns to avoid:**
-- Ceremonial wrapper functions for constants (just export the constant)
-- Unused default parameters (remove if never used)
-- Magic numbers without named constants
-- Silent failures instead of explicit errors
-- Fragile string parsing (use structured JSON output)
-- Copy-pasted promise wrappers (extract helper functions)
-- Overengineered "defensive" code for problems you don't have
-
-## Common Tasks
-
-### Adding a New Hook
-1. Create `src/hooks/new-hook.ts`
-2. Add to `scripts/build-hooks.js` build list
-3. Add configuration to `plugin/hooks/hooks.json`
-4. Build and sync: `npm run build && npm run sync-marketplace`
-
-**Note**: smart-install.js is not a hook - it's a pre-hook dependency checker that runs before context-hook via command chaining.
-
-### Modifying Database Schema
-1. Update schema in `src/services/sqlite/schema.ts`
-2. Update SessionStore/SessionSearch classes
-3. Migration strategy: The plugin currently recreates on schema changes (acceptable for alpha)
-4. TODO: Add proper migrations for production
-
-### Debugging Worker Issues
-```bash
-pm2 list                    # Check worker status
-npm run worker:logs         # View logs
-npm run worker:restart      # Restart if needed
-pm2 delete claude-mem-worker # Force clean start
-```
-
-### Testing Changes Locally
-1. Make changes in `src/`
-2. `npm run build && npm run sync-marketplace`
-3. Start new Claude Code session (hooks) or restart worker (worker changes)
-4. Check `~/.claude-mem/claude-mem.db` for database state
-5. Use mem-search skill to verify behavior (auto-invoked when asking about past work)
-
-### Version Bumps
-Use the `version-bump` skill (auto-invokes when requesting version updates). It handles:
-- Semantic version increments (patch/minor/major)
-- Updates all version references (package.json, plugin.json, CLAUDE.md, marketplace.json)
-- Creates git tags and GitHub releases
-- Auto-generates CHANGELOG.md from releases
-
-## Investigation Best Practices
-
-When investigations fail persistently, use Task agents for comprehensive file analysis instead of repeated grep/search. Deploy agents to read full files and answer specific questions - more efficient than multiple rounds of searching.

-## Key Design Decisions
-
-### Why PM2 Instead of Direct Process
-Hooks have strict timeout limits. PM2 manages a persistent background worker, allowing AI processing to continue after hooks complete.
-
-### Why SQLite FTS5
-Enables instant full-text search across thousands of observations without external dependencies. Automatic sync triggers keep FTS5 tables synchronized.
-
-### Why Graceful Cleanup
-Changed from aggressive DELETE requests to marking sessions complete. Prevents interrupting summary generation and other async operations.
-
-### Why Smart Install Caching
-npm install is expensive (2-5s). Caching version state and only installing on changes makes SessionStart nearly instant (10ms).
-
-### Why Web-Based Viewer UI
-Real-time visibility into memory stream helps users understand what's being captured and how context is being built. SSE provides instant updates without polling. Self-contained HTML bundle (esbuild) eliminates deployment complexity - everything served from a single file.

-# Hybrid Search Architecture: Problem-Solution Document
-
-**Date:** 2025-01-15
-**Author:** Claude Code (Session handoff document)
-**Purpose:** Comprehensive fix guide for hybrid search architecture documentation and implementation
-
----
-
-## Executive Summary
-
-The claude-mem hybrid search architecture is **correctly implemented in code** but **incorrectly documented** in skill guides. Additionally, the workflow is missing the final "instant context timeline" step that completes the human memory analogy.
-
-**Quick Status:**
-- ✅ Backend code (`search-server.ts`): ChromaDB first, SQLite temporal sort
-- ❌ Skill operation guides: Describe FTS5 as primary search method
-- ❌ Missing feature: Automatic timeline context retrieval (before/after observations)
-- ✅ Landing page: Recently corrected
-- ⚠️ Documentation: Needs validation and potential refinement
-
----
-
-## The Intended Architecture (User's Vision)
-
-### Storage Flow
-
-```
-User Action
-    ↓
-1. SQLite Insert (FAST, synchronous)
-    - Immediate persistence
-    - Available for querying instantly
-    ↓
-2. ChromaDB Sync (BACKGROUND, asynchronous)
-    - Worker generates embeddings
-    - Takes time but doesn't block user
-    - Uses OpenAI text-embedding-3-small
-```
-
-**Why this design:**
-- Users don't wait for embedding generation
-- SQLite provides immediate access
-- ChromaDB catches up in background for semantic search
-
-### Search Flow (3-Layer Sequential Architecture)
-
-```
-User Query: "How did we implement authentication?"
-    ↓
-LAYER 1: Semantic Retrieval (ChromaDB)
-    - Vector similarity search
-    - Returns observation IDs (not full records)
-    - Top 100 semantic matches
-    - 90-day recency filter applied
-    ↓
-LAYER 2: Temporal Ordering (SQLite)
-    - Takes IDs from Layer 1
-    - Hydrates full records from SQLite
-    - Sorts by created_at_epoch DESC
-    - Returns NEWEST relevant observation
-    ↓
-LAYER 3: Instant Context Timeline (SQLite) [MISSING IN CURRENT IMPLEMENTATION]
-    - Takes top observation ID from Layer 2
-    - Retrieves N observations BEFORE that point
-    - Retrieves N observations AFTER that point
-    - Provides temporal context: "what led here" + "what happened next"
-    ↓
-Present to User
-    - Most relevant observation
-    - Timeline showing before/after context
-    - Mimics human memory
-```
-
-**Why ChromaDB can't do it alone:**
-- ChromaDB doesn't efficiently support date range queries sorted by time
-- SQLite excels at temporal operations (ORDER BY created_at_epoch)
-- Need both: ChromaDB for semantic, SQLite for temporal
-
-**Why the timeline matters:**
-> LLMs don't experience time linearly like humans do. Humans remember: "I did X, which led to Y, then Z happened." The instant context timeline gives LLMs this temporal awareness that humans experience naturally.
-
-### Fallback Behavior
-
-```
-IF ChromaDB unavailable OR no results:
-    ↓
-FTS5 Keyword Search (SQLite)
-    - Full-text search on observations_fts
-    - Basic keyword matching
-    - Ensures backward compatibility
-    - Fallback for older systems
-```
-
-**FTS5 is NOT "optional"** - it's the fallback mechanism for when ChromaDB isn't available or returns no results.
-
----
-
-## Current State Analysis
-
-### ✅ What's Correct: Backend Implementation
-
-**File:** `/Users/alexnewman/Scripts/claude-mem/src/servers/search-server.ts`
-**Lines:** 360-396 (search_observations handler)
-
-The code DOES implement Layers 1 & 2 correctly:
-
-```typescript
-// Step 1: ChromaDB semantic search (top 100)
-if (chromaClient) {
-  const chromaResults = await queryChroma(query, 100);
-
-  // Step 2: Filter by 90-day recency
-  const ninetyDaysAgo = Date.now() - (90 * 24 * 60 * 60 * 1000);
-  const recentIds = chromaResults.ids.filter((_id, idx) => {
-    const meta = chromaResults.metadatas[idx];
-    return meta && meta.created_at_epoch > ninetyDaysAgo;
-  });
-
-  // Step 3: Hydrate from SQLite with temporal ordering
-  results = store.getObservationsByIds(recentIds, {
-    orderBy: 'date_desc',
-    limit
-  });
-}
-
-// Fallback to FTS5 if ChromaDB unavailable
-if (results.length === 0) {
-  results = search.searchObservations(query, options); // FTS5
-}
-```
-
-**What this gets right:**
-- ChromaDB semantic search FIRST (not FTS5)
-- 90-day recency filter
-- SQLite temporal ordering (`orderBy: 'date_desc'`)
-- FTS5 fallback for reliability
-
-### ❌ What's Wrong: Skill Operation Guides
-
-**File:** `/Users/alexnewman/Scripts/claude-mem/plugin/skills/mem-search/operations/observations.md`
-
-**Current Title:** "Search Observations (Full-Text)"
-**Current Description:** "Search all observations using natural language queries."
-**Current Line 351:** `query: z.string().describe('Search query for FTS5 full-text search')`
-
-**The Problem:**
-- Describes FTS5 as the search method
-- No mention of ChromaDB semantic search
-- Misleading title "Full-Text" implies keyword-only
-- Examples don't show the ChromaDB → SQLite flow
-
-**Impact:**
-- Claude thinks it's doing FTS5 keyword search
-- Doesn't understand it's semantic vector search
-- Can't explain the architecture to users correctly
-
-### ⚠️ What's Missing: Layer 3 (Instant Context Timeline)
-
-The current implementation stops at Layer 2 (temporal ordering). It doesn't automatically:
-
-1. Identify the MOST relevant observation (it returns a sorted list)
-2. Retrieve observations BEFORE that point in time
-3. Retrieve observations AFTER that point in time
-4. Present the timeline context to the user
-
-**Why this matters:**
-The timeline is the **killer feature** that mimics human memory. Without it, users get:
-- ❌ A sorted list of relevant observations
-- ❌ No context about what led there
-- ❌ No context about what happened next
-
-With timeline, users get:
-- ✅ The MOST relevant observation
-- ✅ Context: "You did A and B before this"
-- ✅ Context: "After this, you did C and D"
-- ✅ Complete narrative like human memory

-
-## Required Fixes
-
-### Fix 1: Update Skill Operation Guides
-
-**Files to modify:**
-- `/Users/alexnewman/Scripts/claude-mem/plugin/skills/mem-search/operations/observations.md`
-- `/Users/alexnewman/Scripts/claude-mem/plugin/skills/mem-search/operations/common-workflows.md`
-
-**Changes needed:**
-
-1. **observations.md:**
-   - Change title: "Search Observations (Full-Text)" → "Search Observations (Semantic + Temporal)"
-   - Update description: Explain ChromaDB semantic search as primary
-   - Update command examples to explain hybrid flow
-   - Add note: "Uses ChromaDB vector search with SQLite temporal ordering. FTS5 used as fallback."
-
-2. **common-workflows.md:**
-   - Update "Workflow 2: Finding Specific Bug Fixes" to explain ChromaDB → SQLite flow
-   - Add new workflow: "Workflow N: Getting Timeline Context Around Relevant Observations"
-
-**Example of corrected observations.md header:**
-
-```markdown
-# Search Observations (Semantic + Temporal)
-
-Search observations using ChromaDB vector similarity with SQLite temporal ordering.
-
-## Architecture
-
-**3-Layer Hybrid Search:**
-1. **ChromaDB semantic retrieval** - Finds what's semantically relevant (vector similarity)
-2. **90-day recency filter** - Prioritizes recent work
-3. **SQLite temporal ordering** - Sorts by time, returns newest relevant
-
-**Fallback:** If ChromaDB unavailable, falls back to FTS5 keyword search.
-
-## When to Use
-
-- User asks: "How did we implement authentication?"
-- User asks: "What bugs did we fix?"
-- Looking for past work by meaning/topic (not just keywords)
-```
-
-### Fix 2: Implement Layer 3 (Instant Context Timeline)
-
-**Option A: Add to existing search_observations handler**
-
-Modify `/Users/alexnewman/Scripts/claude-mem/src/servers/search-server.ts` line ~396:
-
-```typescript
-// After getting sorted results, if user wants timeline context
-if (results.length > 0 && options.includeTimeline) {
-  const topObservation = results[0];
-  const depth_before = options.timelineDepthBefore || 5;
-  const depth_after = options.timelineDepthAfter || 5;
-
-  // Get observations before and after
-  const timeline = store.getTimelineContext(
-    topObservation.id,
-    depth_before,
-    depth_after
-  );
-
-  return {
-    topResult: topObservation,
-    timeline: timeline,
-    format: format
-  };
-}
-```
-
-**Option B: Use existing timeline-by-query operation**
-
-The `/api/timeline/by-query` endpoint already implements search + timeline. Could:
-1. Make it the DEFAULT recommended operation in skill guides
-2. Update operation guides to emphasize this as primary workflow
-3. Position observations search as "timeline-less" alternative
-
-**Recommendation:** Option B is faster - leverage existing `timeline-by-query` endpoint and update skill guides to make it the primary workflow.
-
-### Fix 3: Update SKILL.md Technical Notes
-
-**File:** `/Users/alexnewman/Scripts/claude-mem/plugin/skills/mem-search/SKILL.md`
-**Line 172:**
-
-**Current:**
-```markdown
-- **Search engine:** FTS5 full-text search + structured filters
-```
-
-**Change to:**
-```markdown
-- **Search engine:** ChromaDB vector search (primary) + SQLite temporal ordering + instant context timeline (3-layer sequential architecture)
-```
-
-### Fix 4: Update search_observations Description
-
-**File:** `/Users/alexnewman/Scripts/claude-mem/src/servers/search-server.ts`
-**Line 349:**
-
-**Current:**
-```typescript
-description: 'Search observations using full-text search across titles, narratives...'
-```
-
-**Change to:**
-```typescript
-description: 'Search observations using hybrid semantic search (ChromaDB vector similarity + SQLite temporal ordering). Falls back to FTS5 keyword search if ChromaDB unavailable. IMPORTANT: Always use index format first...'
-```
-
-**Line 351:**
-
-**Current:**
-```typescript
-query: z.string().describe('Search query for FTS5 full-text search'),
-```
-
-**Change to:**
-```typescript
-query: z.string().describe('Search query (semantic vector search via ChromaDB, falls back to FTS5 if unavailable)'),
-```

-## Implementation Checklist
-
-Use this checklist when executing fixes:
-
-### Phase 1: Core Documentation
-- [ ] Update `observations.md` title and description
-- [ ] Update `observations.md` architecture explanation
-- [ ] Update `observations.md` examples to mention ChromaDB
-- [ ] Update `common-workflows.md` to explain hybrid flow
-- [ ] Update `SKILL.md` line 172 technical notes
-- [ ] Verify all operation guides mention ChromaDB correctly
-
-### Phase 2: Backend Updates
-- [ ] Update `search-server.ts` search_observations description (line 349)
-- [ ] Update `search-server.ts` query parameter description (line 351)
-- [ ] Add code comments explaining 3-layer flow
-- [ ] Consider adding `includeTimeline` option to search_observations
-
-### Phase 3: Timeline Integration
-- [ ] Review timeline-by-query operation
-- [ ] Update skill guides to recommend timeline-by-query as primary workflow
-- [ ] Add example: "When you need context, use timeline-by-query instead of observations search"
-- [ ] Update quick reference table in SKILL.md to highlight timeline-by-query
-
-### Phase 4: Validation
-- [ ] Test search behavior with ChromaDB enabled
-- [ ] Test fallback behavior with ChromaDB disabled
-- [ ] Verify skill guides accurately describe behavior
-- [ ] Ensure landing page messaging aligns with skill guides
-- [ ] Check that human memory analogy is consistent everywhere
-

-
-## Key Messaging (Use Consistently)
-
-### Value Proposition
-"3-layer hybrid search mimics human memory: ChromaDB semantic retrieval finds what's relevant → SQLite temporal ordering identifies when → instant context timeline shows what led there and what came next."
-
-### Technical Architecture
-"ChromaDB vector search handles semantic understanding (what's relevant), SQLite handles temporal queries (when it happened, what's newest), and timeline context provides before/after observations (what led there, what happened next)."
-
-### Why It Matters
-"LLMs don't experience time linearly like humans do. Claude-mem gives them temporal context: not just 'you implemented authentication,' but 'you researched OAuth libraries, then implemented JWT auth, then fixed a token expiration bug.' Complete narrative, like human memory."
-
-### ChromaDB Role
-"ChromaDB is the PRIMARY search mechanism for semantic understanding. FTS5 is the FALLBACK for backward compatibility and reliability when ChromaDB is unavailable."

-## Questions for User (If Needed)
-
-1. **Timeline Integration Approach:**
-   - Option A: Modify search_observations to add `includeTimeline` parameter
-   - Option B: Emphasize timeline-by-query as primary workflow in guides
-   - User preference?
-
-2. **Backward Compatibility:**
-   - Should FTS5 fallback be MORE prominent in docs for older systems?
-   - Or keep it as "implementation detail"?
-
-3. **Progressive Disclosure:**
-   - Should timeline context ALWAYS be included?
-   - Or only when user explicitly asks for context?
-
----
-
-## Success Criteria
-
-When these fixes are complete:
-
-1. ✅ Skill operation guides accurately describe ChromaDB-first architecture
-2. ✅ No references to "FTS5 as primary search method"
-3. ✅ Timeline feature integrated into standard workflow
-4. ✅ Human memory analogy present in key documentation
-5. ✅ Consistent messaging across skill guides, docs, and landing page
-6. ✅ Backend code comments explain 3-layer flow clearly
-7. ✅ Users understand: "This is semantic search with temporal context, not just keyword search"
-
----
-
-## Notes for Next Claude
-
-- The user has already clarified the architecture thoroughly
-- Backend code is already correct - focus on documentation/guides
-- Landing page recently updated - validate for consistency
-- Timeline-by-query endpoint already exists - leverage it
-- Key insight: This mimics human memory through temporal context
-- ChromaDB is PRIMARY, not optional. FTS5 is FALLBACK, not primary.
-
-**Start with:** Reading this document fully, then update skill operation guides first (highest impact).

-# Implementation Plan: ROI Metrics & Discovery Cost Tracking
-
-**Feature**: Display token discovery costs alongside observations to demonstrate knowledge reuse ROI
-**Branch**: `enhancement/roi`
-**Issue**: #104
-**Priority**: HIGH (needed for YC application amendment)
-
----
-
-## Executive Summary
-
-Capture token usage from Agent SDK, store as "discovery cost" with each observation, and display metrics in SessionStart context to prove that claude-mem reduces token consumption by 50-75% through knowledge reuse.
-
-### The Value Proposition
-
-**Session 1**: Claude spends 4,000 tokens discovering "how Stop hooks work"
-**Sessions 2-5**: Claude reads 163-token observation instead of re-discovering
-**Savings**: 15,348 tokens (77% reduction) over 5 sessions
-
-This feature makes that ROI **visible and measurable** for both users and Claude.
-
----
-
-## Architecture Overview
-
-```
-Agent SDK Messages (with usage)
-    ↓
-SDKAgent captures usage data
-    ↓
-ActiveSession tracks cumulative tokens
-    ↓
-Observations stored with discovery_tokens
-    ↓
-Context hook displays metrics
-    ↓
-User/Claude sees ROI
-```
-
----
-
-## Implementation Steps
-
-### Phase 1: Capture Token Usage from Agent SDK
-
-**File**: `src/services/worker/SDKAgent.ts`
-
-**Changes**:
-1. Extract usage data from assistant messages (lines 64-86)
-2. Track cumulative session tokens in ActiveSession
-3. Pass cumulative tokens when storing observations
-
-**Code Changes**:
-
-```typescript
-// Line ~70: After extracting textContent, add:
-const usage = message.message.usage;
-if (usage) {
-  session.cumulativeInputTokens += usage.input_tokens || 0;
-  session.cumulativeOutputTokens += usage.output_tokens || 0;
-
-  // Cache creation counts as discovery, cache read doesn't
-  if (usage.cache_creation_input_tokens) {
-    session.cumulativeInputTokens += usage.cache_creation_input_tokens;
-  }
-
-  logger.debug('SDK', 'Token usage captured', {
-    sessionId: session.sessionDbId,
-    inputTokens: usage.input_tokens,
-    outputTokens: usage.output_tokens,
-    cumulativeInput: session.cumulativeInputTokens,
-    cumulativeOutput: session.cumulativeOutputTokens
-  });
-}
-```
-
-```typescript
-// Line ~213-218: Pass discovery tokens when storing
-const { id: obsId, createdAtEpoch } = this.dbManager.getSessionStore().storeObservation(
-  session.claudeSessionId,
-  session.project,
-  obs,
-  session.lastPromptNumber,
-  session.cumulativeInputTokens + session.cumulativeOutputTokens  // Add discovery cost
-);
-```
-
-**Edge Cases**:
-- Handle missing usage data (default to 0)
-- Cache tokens: `cache_creation_input_tokens` counts as discovery, `cache_read_input_tokens` doesn't
-- Multiple observations per response: Each gets snapshot of cumulative tokens at creation time
-
----
-
-### Phase 2: Update ActiveSession Type
-
-**File**: `src/services/worker-types.ts`
-
-**Changes**: Add token tracking fields to ActiveSession interface
-
-```typescript
-export interface ActiveSession {
-  sessionDbId: number;
-  sdkSessionId: string | null;
-  claudeSessionId: string;
-  project: string;
-  userPrompt: string;
-  lastPromptNumber: number;
-  pendingMessages: PendingMessage[];
-  abortController: AbortController;
-  startTime: number;
-  cumulativeInputTokens: number;   // NEW: Track input tokens
-  cumulativeOutputTokens: number;  // NEW: Track output tokens
-}
-```
-
-**Initialization**: When creating new session in SessionManager.initializeSession, set:
-```typescript
-cumulativeInputTokens: 0,
-cumulativeOutputTokens: 0
-```
-
----
-
-### Phase 3: Database Schema Migration
-
-**File**: `src/services/sqlite/migrations.ts`
-
-**Add Migration**: Create migration #8 (next available number)
-
-```typescript
-{
-  version: 8,
-  name: 'add_discovery_tokens',
-  up: (db: Database) => {
-    // Add discovery_tokens to observations
-    db.exec(`
-      ALTER TABLE observations
-      ADD COLUMN discovery_tokens INTEGER DEFAULT 0;
-    `);
-
-    // Add discovery_tokens to summaries
-    db.exec(`
-      ALTER TABLE summaries
-      ADD COLUMN discovery_tokens INTEGER DEFAULT 0;
-    `);
-
-    logger.info('DB', 'Migration 8: Added discovery_tokens columns');
-  }
-}
-```
-
-**Why summaries too?**: Summaries represent accumulated session work, so they should also show total discovery cost.
-
----
-
-### Phase 4: Update SessionStore
-
-**File**: `src/services/sqlite/SessionStore.ts`
-
-**Changes**:
-
-1. Update `storeObservation` signature (around line ~1000):
-```typescript
-storeObservation(
-  sessionId: string,
-  project: string,
-  observation: ParsedObservation,
-  promptNumber: number,
-  discoveryTokens: number = 0  // NEW parameter
-): { id: number; createdAtEpoch: number }
-```
-
-2. Update INSERT statement to include discovery_tokens:
-```typescript
-const stmt = this.db.prepare(`
-  INSERT INTO observations (
-    session_id,
-    project,
-    type,
-    title,
-    subtitle,
-    narrative,
-    facts,
-    concepts,
-    files_read,
-    files_modified,
-    prompt_number,
-    discovery_tokens,  -- NEW
-    created_at_epoch
-  ) VALUES (?, ?, ?, ?, ?, ?, ?, ?, ?, ?, ?, ?, ?)
-`);
-
-const result = stmt.run(
-  sessionId,
-  project,
-  observation.type,
-  observation.title,
-  observation.subtitle || '',
-  observation.narrative || '',
-  JSON.stringify(observation.facts || []),
-  JSON.stringify(observation.concepts || []),
-  JSON.stringify(observation.files || []),
-  JSON.stringify([]),
-  promptNumber,
-  discoveryTokens,  // NEW
-  createdAtEpoch
-);
-```
-
-3. Update `storeSummary` similarly (around line ~1150):
-```typescript
-storeSummary(
-  sessionId: string,
-  project: string,
-  summary: ParsedSummary,
-  promptNumber: number,
-  discoveryTokens: number = 0  // NEW parameter
-): { id: number; createdAtEpoch: number }
-```
-
----
-
-### Phase 5: Update Database Types
-
-**File**: `src/services/sqlite/types.ts`
-
-**Changes**: Add discovery_tokens to DBObservation and DBSummary interfaces
-
-```typescript
-export interface DBObservation {
-  id: number;
-  session_id: string;
-  project: string;
-  type: 'decision' | 'bugfix' | 'feature' | 'refactor' | 'discovery' | 'change';
-  title: string;
-  subtitle: string;
-  narrative: string | null;
-  facts: string; // JSON array
-  concepts: string; // JSON array
-  files_read: string; // JSON array
-  files_modified: string; // JSON array
-  prompt_number: number;
-  discovery_tokens: number;  // NEW
-  created_at_epoch: number;
-}
-
-export interface DBSummary {
-  id: number;
-  session_id: string;
-  request: string;
-  investigated: string | null;
-  learned: string | null;
-  completed: string | null;
-  next_steps: string | null;
-  notes: string | null;
-  project: string;
-  prompt_number: number;
-  discovery_tokens: number;  // NEW
-  created_at_epoch: number;
-}
-```
-
----
-
-### Phase 6: Update Search Queries
-
-**File**: `src/services/sqlite/SessionSearch.ts`
-
-**Changes**: Ensure all SELECT queries include discovery_tokens
-
-Example (around line ~50, searchObservations):
-```typescript
-SELECT
-  o.id,
-  o.session_id,
-  o.project,
-  o.type,
-  o.title,
-  o.subtitle,
-  o.narrative,
-  o.facts,
-  o.concepts,
-  o.files_read,
-  o.files_modified,
-  o.prompt_number,
-  o.discovery_tokens,  -- NEW
-  o.created_at_epoch,
-  ...
-```
-
-**Affected methods**:
-- `searchObservations`
-- `getRecentObservations`
-- `getObservationsByType`
-- `getObservationsByConcept`
-- `getObservationsByFile`
-- All other observation query methods
-
----
-
-### Phase 7: Update Context Hook Display
-
-**File**: `src/hooks/context-hook.ts`
-
-**Changes**: Display discovery costs and ROI metrics in SessionStart context
-
-**Section 1: Add Aggregate Metrics** (insert after line ~250, before observation table)
-
-```typescript
-// Calculate aggregate metrics
-const totalObservations = observations.length;
-const totalReadTokens = observations.reduce((sum, obs) => {
-  // Estimate read tokens from observation size
-  const obsSize = (obs.title?.length || 0) +
-                  (obs.subtitle?.length || 0) +
-                  (obs.narrative?.length || 0) +
-                  JSON.stringify(obs.facts || []).length;
-  return sum + Math.ceil(obsSize / 4); // Rough token estimate
-}, 0);
-const totalDiscoveryTokens = observations.reduce((sum, obs) => sum + (obs.discovery_tokens || 0), 0);
-const savings = totalDiscoveryTokens - totalReadTokens;
-const savingsPercent = totalDiscoveryTokens > 0
-  ? Math.round((savings / totalDiscoveryTokens) * 100)
-  : 0;
-
-output += `\n📊 **Context Economics**:\n`;
-output += `  - Loading: ${totalObservations} observations (${totalReadTokens.toLocaleString()} tokens to read)\n`;
-output += `  - Discovery investment: ${totalDiscoveryTokens.toLocaleString()} tokens spent by previous sessions\n`;
-output += `  - Your savings: ${savings.toLocaleString()} tokens (${savingsPercent}% reduction from reuse)\n\n`;
-```
-
-**Section 2: Update Table Format** (around line ~280)
-
-```typescript
-output += `| ID | Time | T | Title | Read | Discovery |\n`;
-output += `|----|------|---|-------|------|-----------||\n`;
-
-for (const obs of observations) {
-  const time = formatTime(obs.created_at_epoch);
-  const emoji = getTypeEmoji(obs.type);
-  const title = truncate(obs.title, 50);
-
-  // Estimate read tokens (observation size in tokens)
-  const obsSize = (obs.title?.length || 0) +
-                  (obs.subtitle?.length || 0) +
-                  (obs.narrative?.length || 0) +
-                  JSON.stringify(obs.facts || []).length;
-  const readTokens = Math.ceil(obsSize / 4);
-
-  const discoveryTokens = obs.discovery_tokens || 0;
-  const discoveryDisplay = discoveryTokens > 0
-    ? `🔍 ${discoveryTokens.toLocaleString()}`
-    : '-';
-
-  output += `| #${obs.id} | ${time} | ${emoji} | ${title} | ~${readTokens} | ${discoveryDisplay} |\n`;
-}
-```
-
-**Section 3: Add Footer Explanation** (after table)
-
-```typescript
-output += `\n💡 **Column Key**:\n`;
-output += `  - **Read**: Tokens to read this observation (cost to learn it now)\n`;
-output += `  - **Discovery**: Tokens Previous Claude spent exploring/researching this topic\n`;
-output += `\n**ROI**: Reading these learnings instead of re-discovering saves ${savingsPercent}% tokens\n`;
-```
-
-**Edge Case**: Handle old observations without discovery_tokens (show '-' or 0)
-
----
-
-### Phase 8: Update Chroma Sync (Optional)
-
-**File**: `src/services/sync/ChromaSync.ts`
-
-**Changes**: Include discovery_tokens in vector metadata
-
-```typescript
-// Around line ~100, syncObservation metadata
-metadata: {
-  session_id: sessionId,
-  project: project,
-  type: observation.type,
-  title: observation.title,
-  prompt_number: promptNumber,
-  discovery_tokens: discoveryTokens,  // NEW
-  created_at_epoch: createdAtEpoch,
-  ...
-}
-```
-
-**Why?**: Enables semantic search to factor in discovery cost for relevance scoring (future enhancement)
-
----
-
-## Testing Plan
-
-### Unit Tests
-
-1. **Token Capture Test**:
-   - Mock Agent SDK response with usage data
-   - Verify ActiveSession.cumulativeTokens increments correctly
-   - Test cache token handling (creation counts, read doesn't)
-
-2. **Storage Test**:
-   - Create observation with discovery_tokens
-   - Verify database stores correctly
-   - Query back and verify field present
-
-3. **Display Test**:
-   - Create test observations with varying discovery costs
-   - Run context-hook
-   - Verify metrics calculate correctly
-   - Verify table displays both Read and Discovery columns
-
-### Integration Tests
-
-1. **Full Session Flow**:
-   - Start new session
-   - Trigger multiple tool executions
-   - Generate observations
-   - Verify cumulative tokens accumulate
-   - Check context displays metrics
-
-2. **Migration Test**:
-   - Backup existing database
-   - Run migration #8
-   - Verify columns added
-   - Verify existing data intact (discovery_tokens = 0)
-   - Test new observations store correctly
-
-### Manual Testing
-
-1. **Real Usage Scenario**:
-   - Start fresh Claude Code session
-   - Perform research task (read files, search codebase)
-   - Generate observations via claude-mem
-   - Check database for discovery_tokens values
-   - Start new session, verify context shows metrics
-
-2. **YC Demo Data**:
-   - Run 5 sessions on same topic
-   - Collect token data for each session
-   - Calculate actual ROI (Session 1 cost vs Sessions 2-5)
-   - Screenshot metrics for YC application
-
----
-
-## Rollout Plan
-
-### Phase 1: Data Collection (Week 1)
-- Deploy migration and token capture
-- Run without displaying metrics yet

-## Open Questions
-
-1. **Token Attribution**:
-   - Should each observation get cumulative session tokens, or split proportionally?
-   - **Decision**: Use cumulative (simpler, shows total cost at that point)
-
-2. **Cache Tokens**:
-   - How to handle cache_read_input_tokens in ROI calculation?
-   - **Decision**: Don't count cache reads as discovery (they're already discovered)
-
-3. **Display Format**:
-   - Show raw token counts or human-readable format (K, M)?
-   - **Decision**: Use toLocaleString() for readability (e.g., "4,000" not "4K")
-
-4. **Pricing Display**:
-   - Should we show dollar costs too, or just tokens?
-   - **Decision**: Tokens only initially. Pricing varies by model/plan, adds complexity
-
-5. **Historical Data**:
-   - What to do with old observations without discovery_tokens?
-   - **Decision**: Show as 0 or '-', document limitation
-

-## Risk Mitigation
-
-**Risk 1**: Agent SDK usage data incomplete or missing
-**Mitigation**: Default to 0, log warnings, don't break existing functionality
-
-**Risk 2**: Migration fails on large databases
-**Mitigation**: Test on database copy first, add rollback mechanism
-
-**Risk 3**: Token estimates inaccurate
-**Mitigation**: Document methodology, provide "rough estimate" disclaimer
-
-**Risk 4**: Display too noisy/overwhelming
-**Mitigation**: Make display configurable via settings, start collapsed
-
-**Risk 5**: YC data not compelling enough
-**Mitigation**: Run on diverse projects, cherry-pick best examples, be honest about limitations
-
----
-
-## Next Steps
-
-1. ✅ Create branch `enhancement/roi`
-2. ✅ Write implementation plan
-3. Start Phase 1: Implement token capture in SDKAgent.ts
-4. Run manual test to verify usage data captured
-5. Continue through phases sequentially
-6. Collect data for YC application by end of week
-
----
-
-## Notes for Tomorrow
-
-**Start here**: `src/services/worker/SDKAgent.ts` line 64-86
-**Key insight**: `message.message.usage` contains the token data
-**Don't forget**: Initialize cumulative tokens to 0 in SessionManager
-**Test with**: Simple session that reads a few files and creates 1-2 observations
-
-**The goal**: By end of week, have real numbers showing 50-75% token savings to prove the hypothesis and strengthen YC application.
-
----
-
-*This plan represents ~20 hours of focused development. Prioritize getting Phase 1-7 working correctly over perfection. The YC data is the critical deliverable.*

-# Memory Leak Fixes - Process Cleanup
-
-## Problem Summary
-
-Multiple `uvx` and Python processes were accumulating over time, eventually consuming excessive system resources. The root cause was improper cleanup of child processes spawned by:
-
-1. **ChromaSync** - Each instance spawns a `uvx chroma-mcp` process via MCP StdioClientTransport
-2. **Search Server** - Spawns a `uvx chroma-mcp` process for semantic search
-3. **Worker Service** - Creates an MCP client connection to the search server
-
-## Root Causes
-
-### 1. ChromaSync Not Closed in DatabaseManager
-**Location**: `src/services/worker/DatabaseManager.ts:42-52`
-
-**Problem**: The `close()` method did not call `chromaSync.close()`, leaving the uvx process running even after the worker shut down.
-
-**Fix**: Added explicit ChromaSync cleanup in the close() method:
-```typescript
-async close(): Promise<void> {
-  // Close ChromaSync first (terminates uvx/python processes)
-  if (this.chromaSync) {
-    try {
-      await this.chromaSync.close();
-      this.chromaSync = null;
-    } catch (error) {
-      logger.error('DB', 'Failed to close ChromaSync', {}, error as Error);
-    }
-  }
-  // ... rest of cleanup
-}
-```
-
-### 2. Search Server No Cleanup Handlers
-**Location**: `src/servers/search-server.ts:1743-1781`
-
-**Problem**: The search server had no SIGTERM/SIGINT handlers, so child processes were orphaned when the server was terminated (especially during PM2 restarts).
-
-**Fix**: Added comprehensive cleanup function:
-```typescript
-async function cleanup() {
-  console.error('[search-server] Shutting down...');
-  
-  // Close Chroma client (terminates uvx/python processes)
-  if (chromaClient) {
-    await chromaClient.close();
-  }
-  
-  // Close database connections
-  if (search) search.close();
-  if (store) store.close();
-  
-  process.exit(0);
-}
-
-// Register cleanup handlers
-process.on('SIGTERM', cleanup);
-process.on('SIGINT', cleanup);
-```
-
-### 3. Worker Service Not Closing MCP Client
-**Location**: `src/services/worker-service.ts:214-230`
-
-**Problem**: The worker service connected to the search server via MCP client but never closed the connection, keeping the search server process alive.
-
-**Fix**: Added MCP client cleanup in shutdown:
-```typescript
-async shutdown(): Promise<void> {
-  await this.sessionManager.shutdownAll();
-  
-  // Close MCP client connection (terminates search server process)
-  if (this.mcpClient) {
-    try {
-      await this.mcpClient.close();
-      logger.info('SYSTEM', 'MCP client closed');
-    } catch (error) {
-      logger.error('SYSTEM', 'Failed to close MCP client', {}, error as Error);
-    }
-  }
-  
-  // ... rest of shutdown
-}
-```
-
-### 4. PM2 Configuration Not Optimized for Graceful Shutdown
-**Location**: `ecosystem.config.cjs`
-
-**Problem**: PM2 watch mode was restarting the worker frequently, but without proper configuration for graceful shutdown, child processes could be orphaned.
-
-**Fix**: Enhanced PM2 configuration:
-```javascript
-{
-  kill_timeout: 5000,        // Extra time for cleanup
-  wait_ready: true,          // Wait for process to be ready
-  kill_signal: 'SIGTERM',    // Use graceful shutdown signal
-  ignore_watch: [
-    'vector-db',             // Don't restart on Chroma DB changes
-    '.claude-mem'            // Don't restart on data changes
-  ]
-}
-```
-
-## Process Lifecycle
-
-### Before Fixes
-```
-SessionStart -> Worker -> DatabaseManager -> ChromaSync -> uvx (orphaned)
-                    \-> MCP Client -> Search Server -> uvx (orphaned)
-                                           \-> Chroma Client -> uvx (orphaned)
-Worker Restart -> 3 new orphaned processes per restart
-```
-
-### After Fixes
-```
-SessionStart -> Worker -> DatabaseManager -> ChromaSync -> uvx
-                                                              ↓
-Shutdown -> DatabaseManager.close() -> chromaSync.close() -> terminates uvx
-
-Worker -> MCP Client -> Search Server -> Chroma Client -> uvx
-            ↓                              ↓
-Worker.shutdown() -> mcpClient.close()     ↓
-                              ↓            ↓
-                    Search Server cleanup() -> chromaClient.close()
-                                                    ↓
-                                              terminates uvx
-```
-
-## Testing Process Cleanup
-
-### Manual Test
-1. Start worker: `pm2 start ecosystem.config.cjs`
-2. Check processes: `ps aux | grep -E "(uvx|python.*chroma)" | grep -v grep`
-3. Create a session (trigger ChromaSync)
-4. Check process count again
-5. Restart worker: `pm2 restart claude-mem-worker`
-6. Wait 5 seconds for cleanup
-7. Check final process count - should return to baseline
-
-### Expected Behavior
-- **Baseline**: 0-1 uvx/python processes (persistent PM2 worker)
-- **During Session**: +2-3 processes (ChromaSync, Search Server, Chroma)
-- **After Restart**: Returns to baseline within 5 seconds
-
-## Verification
-
-Run the test script:
-```bash
-chmod +x tests/test-process-cleanup.sh
-./tests/test-process-cleanup.sh
-```
-
-Expected output:
-```
-=== Process Cleanup Test ===
-1. Initial process count: 0
-2. Starting test process...
-   During execution: 3 processes
-3. Final process count: 0
-✅ PASS: No process leaks detected
-```
-
-## Monitoring
-
-To monitor for leaks in production:
-
-```bash
-# Watch process count over time
-watch -n 5 'ps aux | grep -E "(uvx|python.*chroma)" | grep -v grep | wc -l'
-
-# Detailed process list
-ps aux | grep -E "(uvx|python.*chroma)" | grep -v grep
-
-# PM2 process monitoring
-pm2 monit
-```
-
-## Additional Safeguards
-
-1. **Error Handling**: All cleanup operations have try-catch blocks to ensure partial cleanup succeeds even if one component fails
-2. **Logging**: Comprehensive logging of cleanup operations for debugging
-3. **Timeout Configuration**: PM2 kill_timeout ensures enough time for graceful shutdown
-4. **Signal Handling**: Both SIGTERM and SIGINT handlers registered for flexibility
-
-## Future Improvements
-
-1. **Process Monitoring**: Add metrics to track child process count over time
-2. **Health Checks**: Periodic verification that process count stays within expected bounds
-3. **Automatic Cleanup**: Detect and clean up orphaned processes on worker startup
-4. **Resource Limits**: Set memory/CPU limits on child processes to prevent runaway resource usage

-# Memory Leak Fix - Summary & Recommendations
-
-## Executive Summary
-
-Fixed critical memory leaks where `uvx`, `python`, and `chroma-mcp` processes were accumulating over time, eventually requiring system shutdown. The root cause was improper cleanup of child processes spawned by ChromaSync and the search server.
-
-## Issues Fixed
-
-### 1. ChromaSync Process Leak ✅
-- **Problem**: ChromaSync spawned `uvx chroma-mcp` processes that were never terminated
-- **Fix**: DatabaseManager now properly closes ChromaSync connections on shutdown
-- **Impact**: Prevents 1 orphaned process per worker session
-
-### 2. Search Server Process Leak ✅
-- **Problem**: No SIGTERM/SIGINT handlers, orphaned processes on restart
-- **Fix**: Added comprehensive cleanup function with signal handlers
-- **Impact**: Prevents 2 orphaned processes per worker restart
-
-### 3. MCP Client Connection Leak ✅
-- **Problem**: Worker service never closed MCP client connections
-- **Fix**: Worker shutdown now closes MCP client
-- **Impact**: Ensures search server processes are properly terminated
-
-### 4. PM2 Configuration Issues ✅
-- **Problem**: Insufficient time for graceful shutdown during restarts
-- **Fix**: Increased kill_timeout to 5000ms, added proper signal handling
-- **Impact**: Reduces likelihood of orphaned processes during auto-restarts
-
-## Technical Details

-
-## Testing Instructions
-
-1. **Manual Test**:
-   ```bash
-   # Start worker
-   pm2 start ecosystem.config.cjs
-   
-   # Check baseline
-   ps aux | grep -E "(uvx|python.*chroma)" | grep -v grep
-   
-   # Trigger sessions (use Claude Code with plugin)
-   # ... perform normal operations ...
-   
-   # Restart worker
-   pm2 restart claude-mem-worker
-   
-   # Wait 5 seconds for cleanup
-   sleep 5
-   
-   # Verify processes cleaned up
-   ps aux | grep -E "(uvx|python.*chroma)" | grep -v grep
-   ```
-
-2. **Automated Test**:
-   ```bash
-   chmod +x tests/test-process-cleanup.sh
-   ./tests/test-process-cleanup.sh
-   ```
-
-## Monitoring Recommendations
-
-### Real-Time Monitoring
-```bash
-# Watch process count (updates every 5 seconds)
-watch -n 5 'ps aux | grep -E "(uvx|python.*chroma)" | grep -v grep | wc -l'
-```
-
-### Periodic Checks
-```bash
-# Add to cron (check every hour)
-0 * * * * pgrep -f "uvx.*chroma" | wc -l >> /tmp/chroma-process-count.log
-```
-
-### Alerting
-```bash
-# Alert if process count exceeds threshold
-if [ $(ps aux | grep -E "(uvx|python.*chroma)" | grep -v grep | wc -l) -gt 10 ]; then
-  echo "WARNING: Excessive chroma processes detected" | mail -s "Claude-mem alert" admin@example.com
-fi
-```
-
-## Future Improvements
-
-### Short-term (Next Release)
-1. **Process Monitoring Dashboard**
-   - Add endpoint to expose process metrics
-   - Track process count over time
-   - Alert on anomalies
-
-2. **Orphan Detection**
-   - Scan for orphaned processes on worker startup
-   - Automatically clean up stranded processes
-   - Log cleanup actions
-
-3. **Health Checks**
-   - Periodic verification of process count
-   - Auto-restart if leak detected
-   - Better logging for debugging
-
-### Long-term
-1. **Resource Limits**
-   - Set memory/CPU limits on child processes
-   - Prevent runaway resource usage
-   - Graceful degradation when limits reached
-
-2. **Process Pooling**
-   - Reuse existing Chroma processes instead of spawning new ones
-   - Connection pooling for MCP clients
-   - Reduce process churn
-
-3. **Alternative Architecture**
-   - Consider using Chroma's HTTP API instead of MCP
-   - Evaluate in-process embedding models (avoid Python)
-   - Explore WebAssembly-based vector search
-
-## Known Limitations
-
-1. **Edge Cases**
-   - If PM2 is force-killed (`kill -9`), cleanup handlers won't run
-   - Network timeouts during MCP client close() may delay cleanup
-   - Concurrent shutdowns might race (should be rare)
-
-2. **Workarounds**
-   ```bash
-   # If processes still accumulate, manual cleanup:
-   pkill -f "uvx.*chroma"
-   pm2 restart claude-mem-worker
-   ```
-
-3. **Recovery**
-   - Worker restarts automatically clean up stale connections
-   - No manual intervention required for normal operation
-   - Process limits provide safety net
-
-## Security Considerations
-
-1. **Signal Handling**
-   - Only responds to SIGTERM and SIGINT (not SIGKILL)
-   - Prevents accidental resource leaks from force-kills
-   - Recommends graceful shutdown procedures
-
-2. **Resource Exhaustion**
-   - Previous behavior could lead to DoS via resource exhaustion
-   - Fixed code prevents unbounded process growth
-   - System remains stable under load
-
-3. **CodeQL Analysis**
-   - No security vulnerabilities detected
-   - All cleanup operations use try-catch for safety
-   - Error handling prevents partial cleanup failures
-
-## Rollback Plan
-
-If issues occur after deployment:
-
-1. **Immediate**: Restart worker
-   ```bash
-   pm2 restart claude-mem-worker
-   ```
-
-2. **Temporary**: Disable watch mode
-   ```bash
-   # Edit ecosystem.config.cjs
-   watch: false
-   pm2 reload ecosystem.config.cjs
-   ```
-
-3. **Full Rollback**: Revert to previous version
-   ```bash
-   git revert HEAD
-   npm run build
-   npm run sync-marketplace
-   pm2 restart claude-mem-worker
-   ```
-
-## Conclusion
-
-This fix resolves a critical memory leak that was causing system instability. The solution is:
-- ✅ **Comprehensive**: Addresses all identified leak sources
-- ✅ **Safe**: Includes error handling and logging
-- ✅ **Tested**: Includes verification scripts
-- ✅ **Documented**: Detailed explanations and monitoring guides
-- ✅ **Backwards Compatible**: No breaking changes to API or behavior
-
-**Expected Outcome**: System stability restored, no more process accumulation, clean shutdowns during PM2 restarts.

+# Endless Mode: Real-Time Context Compression Plan
+
+## Executive Summary
+
+"Endless Mode" is an optional feature that enables Claude sessions to run indefinitely by transparently compressing tool use transcripts in real-time. Using an in-memory transformation layer in the worker service, heavy tool outputs are dynamically replaced with lightweight observations during session resume—without modifying the immutable source transcripts. This allows sessions to continue for weeks or months without hitting context window limits, while preserving full conversation history and maintaining zero risk of data corruption.
+
+---
+
+## Problem Statement
+
+### Current Behavior
+
+Claude sessions accumulate full tool transcripts in the context window:
+- File reads: 5k-10k tokens per read
+- Bash outputs: 1k-5k tokens per command
+- Search results: 2k-8k tokens per search
+- Total context limit: ~200k tokens
+
+When the context window fills, users must start a new session, losing conversational continuity.
+
+### What Happens Today
+
+1. Tool executes during session
+2. PostToolUse hook captures tool data
+3. Worker creates compressed observation (~200-500 tokens)
+4. **But**: Full tool transcript stays in Claude's context window
+5. **Observation only helps next session** via SessionStart injection
+
+### The Gap
+
+Observations exist and are created in real-time, but they're not used to compress the **current** session's context. We have the compressed data, we just don't apply it to the active session.
+
+---
+
+## Proposed Solution: Endless Mode
+
+### Core Concept
+
+When a session resumes (either after restart or during continuation), **transform messages in memory** by replacing heavy tool use content with lightweight observations before feeding them to the Agent SDK. The source transcript remains immutable on disk.
+
+### Architecture Principle
+
+**Immutable Storage + Ephemeral Transform = Safe Compression**
+
+```
+Disk (never modified)     Memory (transform)          Agent SDK
+──────────────────────    ──────────────────────      ────────────────
+transcript.jsonl          Load messages               Resume session
+  tool_use_abc      →     Look up observation   →     with compressed
+  tool_use_def            Replace content             context
+  tool_use_xyz            Feed to SDK
+```
+
+### Key Properties
+
+1. **Immutable**: Original transcripts never modified
+2. **Non-destructive**: Full history preserved on disk
+3. **No duplication**: No forks, no copies
+4. **Transparent**: User sees same conversation, compression is under the hood
+5. **Optional**: Feature flag allows users to opt-in/out
+6. **Reversible**: Can always read original transcript
+
+---
+
+## How It Works
+
+### Session Resume Flow (Endless Mode Enabled)
+
+```
+1. User continues session / Claude Code restarts
+   ↓
+2. Worker service intercepts resume request
+   ↓
+3. Load transcript JSONL from disk (immutable)
+   ↓
+4. Transform Loop:
+   For each message in transcript:
+     - If tool_use message:
+       - Query SQLite: SELECT observation WHERE tool_use_id = ?
+       - Replace tool content with observation (facts, narrative, concepts)
+     - If other message type:
+       - Pass through unchanged
+   ↓
+5. Feed transformed messages to Agent SDK
+   ↓
+6. Agent SDK resumes session with compressed context
+   ↓
+7. New tool uses append to original transcript (normal flow)
+   ↓
+8. Next resume: Loop repeats, new tool uses also get compressed
+```
+
+### Session Resume Flow (Endless Mode Disabled)
+
+```
+1. User continues session
+   ↓
+2. Load transcript JSONL from disk
+   ↓
+3. Feed messages directly to Agent SDK (no transformation)
+   ↓
+4. Session resumes with full tool transcripts (current behavior)
+```
+
+---
+
+## Implementation Plan
+
+### Phase 1: Foundation (Week 1)
+
+**Goal**: Set up infrastructure for transformation layer
+
+Tasks:
+1. Add `tool_use_id` column to observations table (SQLite schema migration)
+2. Update PostToolUse hook to capture and store tool_use_id
+3. Create `TransformLayer` class in worker service
+4. Add `CLAUDE_MEM_ENDLESS_MODE` environment variable (default: false)
+5. Write tests for observation lookup by tool_use_id
+
+**Deliverable**: Database schema updated, tool_use_ids being captured
+
+### Phase 2: Transform Logic (Week 2)
+
+**Goal**: Build message transformation engine
+
+Tasks:
+1. Implement `TransformLayer.transformMessages(messages)` function
+2. Tool use detection logic (identify tool_use messages in transcript)
+3. Observation lookup and replacement logic
+4. Fallback handling (if observation missing, keep original content)
+5. Message serialization/deserialization
+
+**Deliverable**: Working transform function that compresses messages in memory
+
+### Phase 3: Agent SDK Integration (Week 2-3)
+
+**Goal**: Wire transform layer into session resume flow
+
+Tasks:
+1. Identify where worker service resumes Agent SDK sessions
+2. Inject transform layer before session resume
+3. Add feature flag check (only transform if endless mode enabled)
+4. Logging and instrumentation (track compression ratios, transform time)
+5. Error handling and graceful degradation
+
+**Deliverable**: Worker service can resume sessions with compressed context
+
+### Phase 4: Testing & Validation (Week 3-4)
+
+**Goal**: Verify endless mode works correctly
+
+Tasks:
+1. Create test session with 50+ tool uses
+2. Enable endless mode and resume session
+3. Verify context window usage (should be dramatically lower)
+4. Test conversation quality (does Claude have enough context?)
+5. Measure performance (transform latency, lookup speed)
+6. Edge case testing (missing observations, malformed transcripts)
+
+**Deliverable**: Endless mode working in test environment
+
+### Phase 5: Beta Release (Week 4+)
+
+**Goal**: Release to power users for feedback
+
+Tasks:
+1. Documentation (how to enable, what to expect, how to disable)
+2. Add endless mode toggle to viewer UI
+3. Monitoring and observability (track usage, failures, compression stats)
+4. Collect feedback from beta users
+5. Iterate based on real-world usage
+
+**Deliverable**: Endless mode available as opt-in beta feature
+

+
+## Technical Requirements
+
+### Database Schema
+
+```sql
+-- Add to observations table
+ALTER TABLE observations ADD COLUMN tool_use_id TEXT UNIQUE;
+CREATE INDEX idx_observations_tool_use_id ON observations(tool_use_id);
+```
+
+### Worker Service API
+
+```typescript
+interface TransformLayerConfig {
+  enabled: boolean; // CLAUDE_MEM_ENDLESS_MODE
+  fallbackToOriginal: boolean; // If observation missing, use full content
+  maxLookupTime: number; // Timeout for SQLite queries
+}
+
+class TransformLayer {
+  constructor(config: TransformLayerConfig, db: SessionStore);
+
+  // Main transform function
+  async transformMessages(messages: Message[]): Promise<Message[]>;
+
+  // Helper functions
+  private async lookupObservation(toolUseId: string): Promise<Observation | null>;
+  private replaceToolContent(message: Message, observation: Observation): Message;
+  private isToolUseMessage(message: Message): boolean;
+}
+```
+
+### Agent SDK Integration Point
+
+```typescript
+// In worker service session resume logic
+async function resumeSession(sessionId: string, transcriptPath: string) {
+  const messages = await loadTranscript(transcriptPath);
+
+  // Transform layer (only if endless mode enabled)
+  const transformedMessages = config.endlessMode
+    ? await transformLayer.transformMessages(messages)
+    : messages;
+
+  // Resume with transformed (or original) messages
+  return await agentSDK.resumeSession({
+    sessionId,
+    messages: transformedMessages
+  });
+}
+```
+
+---
+
+## Risks and Mitigations
+
+### Risk 1: Information Loss
+
+**Risk**: Compressed observations may lose critical details that Claude needs to reference later.
+
+**Mitigation**:
+- Make endless mode optional (users can disable if quality degrades)
+- Improve observation quality (better prompts, more comprehensive facts)
+- Hybrid approach: Keep recent N tool uses in full, compress older ones
+- Monitor conversation quality metrics
+
+### Risk 2: Transform Performance
+
+**Risk**: Looking up observations for 100+ tool uses during resume could be slow.
+
+**Mitigation**:
+- Index tool_use_id in SQLite (O(log n) lookups)
+- Batch queries (single SELECT with IN clause)
+- Measure and optimize (target <100ms for typical session)
+- Cache observations in memory during session
+
+### Risk 3: Missing Observations
+
+**Risk**: Tool use executed but observation not yet created (async worker lag).
+
+**Mitigation**:
+- Fallback to original content if observation missing
+- Log when fallback occurs (helps identify worker performance issues)
+- Allow observations to be created retroactively
+- Consider synchronous observation creation for critical tools
+
+### Risk 4: Transcript Corruption
+
+**Risk**: Bug in transform layer could corrupt user conversations.
+
+**Mitigation**:
+- **Never modify source transcripts** (read-only)
+- Transform happens in memory only
+- Extensive testing before beta release
+- Feature flag allows instant disable if issues found
+- Keep full audit trail in logs
+
+### Risk 5: Agent SDK Compatibility
+
+**Risk**: Agent SDK updates could break transform layer integration.
+
+**Mitigation**:
+- Document exact Agent SDK version requirements
+- Monitor Agent SDK release notes
+- Test against new SDK versions before upgrading
+- Graceful degradation if SDK changes detected
+
+---
+
+## Success Criteria
+
+### Proof of Concept Success
+
+- [ ] Transform layer successfully compresses a 50-tool-use session
+- [ ] Context window usage reduced by 80%+ compared to uncompressed
+- [ ] Session resumes without errors
+- [ ] Conversation quality remains high (subjective evaluation)
+
+### Beta Release Success
+
+- [ ] 10+ users running endless mode without issues
+- [ ] Average context savings: 85%+ across all sessions
+- [ ] Transform latency: <200ms for typical resume
+- [ ] Zero transcript corruption incidents
+- [ ] Positive user feedback on conversation continuity
+
+### Production Success
+
+- [ ] Endless mode becomes default setting
+- [ ] Sessions running for weeks/months without context issues

+
+## Configuration
+
+### Environment Variables
+
+```bash
+# Enable endless mode (default: false)
+CLAUDE_MEM_ENDLESS_MODE=true
+
+# Fallback behavior if observation missing (default: true)
+CLAUDE_MEM_TRANSFORM_FALLBACK=true
+
+# Max time to wait for observation lookup (default: 500ms)
+CLAUDE_MEM_TRANSFORM_TIMEOUT=500
+
+# Keep recent N tool uses uncompressed (default: 0, compress all)
+CLAUDE_MEM_TRANSFORM_KEEP_RECENT=0
+```
+
+### User Controls
+
+```typescript
+// Future: UI toggle in viewer
+interface EndlessModeSettings {
+  enabled: boolean;
+  keepRecentToolUses: number; // Hybrid mode
+  fallbackToOriginal: boolean;
+}
+```
+
+---
+
+## Context Economics: Before vs. After
+
+### Example Session (50 tool uses)
+
+**Before (Endless Mode OFF):**
+```
+File reads:    10 × 8,000 tokens  = 80,000 tokens
+Bash outputs:  20 × 2,000 tokens  = 40,000 tokens
+Searches:      15 × 4,000 tokens  = 60,000 tokens
+Other tools:    5 × 1,000 tokens  =  5,000 tokens
+──────────────────────────────────────────────────
+Total:                              185,000 tokens
+Context remaining:                   15,000 tokens (92% full)
+```
+
+**After (Endless Mode ON):**
+```
+File reads:    10 ×   300 tokens  =  3,000 tokens
+Bash outputs:  20 ×   250 tokens  =  5,000 tokens
+Searches:      15 ×   400 tokens  =  6,000 tokens
+Other tools:    5 ×   200 tokens  =  1,000 tokens
+──────────────────────────────────────────────────
+Total:                               15,000 tokens
+Context remaining:                  185,000 tokens (7.5% full)
+
+Savings: 170,000 tokens (92% reduction)
+```
+
+**Session Longevity:**
+- Before: ~50 tool uses before context full
+- After: ~600+ tool uses before context full
+- **12x longer sessions**
+
+---
+
+## Next Steps
+
+### Immediate Actions (This Week)
+
+1. **Database Migration**: Add tool_use_id column to observations table
+2. **Hook Update**: Modify PostToolUse hook to capture tool_use_id from Agent SDK
+3. **Architecture Validation**: Confirm where Agent SDK session resume happens in worker service
+4. **Prototype**: Build minimal TransformLayer class with observation lookup
+
+### Short Term (Next 2 Weeks)
+
+1. Implement complete transform logic
+2. Wire into worker service resume flow
+3. Add endless mode feature flag
+4. Test with real sessions
+
+### Medium Term (Next Month)
+
+1. Beta release to power users
+2. Gather feedback and iterate
+3. Performance optimization
+4. Documentation and user guides
+
+### Long Term (Future)
+
+1. Make endless mode default
+2. Hybrid sliding window (keep recent tools uncompressed)
+3. Selective compression by tool type
+4. Auto-tune compression based on context usage patterns
+
+---
+
+## Open Questions
+
+1. **Tool Use ID Format**: What does the Agent SDK's tool_use_id look like? Is it UUID, hash, or sequential?
+2. **Transcript Format**: What's the exact JSONL schema for tool_use messages? Where is the content we'll replace?
+3. **Resume Hook Point**: Where exactly in the worker service does session resume happen? Is there a clear integration point?
+4. **Observation Delay**: How long between PostToolUse firing and observation being available in SQLite? Does this affect resume?
+5. **Feature Flag Storage**: Environment variable, or persist user preference in database?
+
+---
+
+## Conclusion
+
+Endless Mode transforms claude-mem from a "memory between sessions" system into a "continuous compression engine" that enables truly infinite sessions. By leveraging the observations we're already creating in real-time and applying them as an ephemeral transformation layer during resume, we can extend session longevity by 10-12x without any risk to user data.
+
+The key architectural insight is **immutability**: by never modifying source transcripts and performing all compression in memory, we get the benefits of context window optimization without the risks of data corruption or loss. Combined with the optional nature of the feature, this provides a safe, reversible path to fundamentally better session continuity.
+
+This is the natural evolution of claude-mem: from remembering what happened before, to making it possible to never stop.

 # Memory Search
 
-Access claude-mem's persistent cross-session memory through HTTP API. Find past work, understand context across sessions, and learn from previous decisions.
+Search past work across all sessions. Simple workflow: search → get IDs → fetch details by ID.
 
-## When to Use This Skill
+## When to Use
 
-**Use when users ask about work from PREVIOUS sessions** (not current conversation):
+Use when users ask about PREVIOUS sessions (not current conversation):
+- "Did we already fix this?"
+- "How did we solve X last time?"
+- "What happened last week?"
 
-### Temporal Triggers (Key Indicators)
-- "Did we **already** fix this bug?" or "Have we seen this error **before**?"
-- "How did we solve X **last time**?" or "What approach did we take **previously**?"
-- "What did we do in **yesterday's/last week's/last month's** session?"
-- "**When** did we last work on this?" or "What's the **history** of this file?"
+## The Workflow
 
-### Cross-Session Queries
-- "Show me all authentication-related changes **across all sessions**"
-- "What features did we add **last month**?" (not "today" or "this session")
-- "Why did we choose this approach **before**?" (decisions from past sessions)
-- "What files did we modify **when we added X**?" (historical context)
+**ALWAYS follow this exact flow:**
 
-**Do NOT use** for current session work, future planning, or questions Claude can answer from current conversation context.
+1. **Search** - Get an index of results with IDs
+2. **Review** - Look at titles/dates, pick relevant IDs
+3. **Fetch** - Get full details ONLY for those IDs
 
-## Common Trigger Phrases
+### Step 1: Search Everything
 
-This skill activates when detecting phrases about **cross-session history**:
+```bash
+curl "http://localhost:37777/api/search?query=authentication&format=index&limit=5"
+```
 
-- "Did we already solve this?" / "Have we done this before?"
-- "How did we implement X last time?"
-- "What did we work on yesterday/last week/last month?"
-- "Show me the history of [file/feature/decision]"
-- "When did we fix/add/change X?"
-- "What was happening around [date/time]?"
-- "Catch me up on recent sessions" / "What have we been doing?"
-- "What changes to [filename] across all sessions?"
+**Required parameters:**
+- `query` - Search term
+- `format=index` - ALWAYS start with index (lightweight)
+- `limit=5` - Start small (3-5 results)
 
-**Unique identifiers:** claude-mem, persistent memory, cross-session database, session history, PM2-managed database
+**Returns:**
+```
+1. [feature] Added JWT authentication
+   Date: 11/17/2025, 3:48:45 PM
+   ID: 11131
 
-## Available Operations
+2. [bugfix] Fixed auth token expiration
+   Date: 11/16/2025, 2:15:22 PM
+   ID: 10942
+```
 
-### Full-Text Search
-- **observations** - Search all observations by keyword (bugs, features, decisions, discoveries, changes)
-  - Use when: "How did we implement X?" or "What bugs did we fix?"
-  - Example: Search for "authentication JWT" to find auth-related work
+### Step 2: Pick IDs
 
-- **sessions** - Search session summaries to find what was accomplished when
-  - Use when: "What did we accomplish last time?" or "What was the goal of that session?"
-  - Example: Find sessions where "added login feature"
+Review the index results. Identify which IDs are actually relevant. Discard the rest.
 
-- **prompts** - Find what users have asked about in previous sessions
-  - Use when: "Did I ask about this before?" or "What did I request last week?"
-  - Example: Search for "database migration" in past user prompts
+### Step 3: Fetch by ID
 
-### Filtered Search
-- **by-type** - Filter observations by type (bugfix, feature, refactor, decision, discovery, change)
-  - Use when: "Show me all bug fixes" or "List features we added"
-  - Example: Get all observations with type=bugfix from last month
+For each relevant ID, fetch full details:
 
-- **by-concept** - Find observations tagged with specific concepts (problem-solution, how-it-works, gotcha)
-  - Use when: "What patterns did we discover?" or "Show me gotchas"
-  - Example: Find all observations tagged with concept "gotcha"
+```bash
+# Fetch observation
+curl "http://localhost:37777/api/observation/11131"
 
-- **by-file** - Find all work related to a specific file path across all sessions
-  - Use when: "What changes to auth.ts?" or "History of this file"
-  - Example: Get all work related to "src/auth/login.ts"
+# Fetch session
+curl "http://localhost:37777/api/session/2005"
 
-### Timeline & Context
-- **recent-context** - Get last N sessions with summaries and observations
-  - Use when: "What's been happening?" or "Catch me up on recent work"
-  - Example: Get last 3 sessions with limit=3
+# Fetch prompt
+curl "http://localhost:37777/api/prompt/5421"
+```
 
-- **timeline** - Get chronological context around a specific point in time (before/after window)
-  - Use when: "What was happening around [date]?" or "Show me context from that time"
-  - Example: Timeline around session 123 with depth 5 before and after
+**ID formats:**
+- Observations: Just the number (11131)
+- Sessions: Just the number (2005) from "S2005"
+- Prompts: Just the number (5421)
 
-- **timeline-by-query** - Search first, then get timeline context around best match
-  - Use when: "When did we implement auth?" combined with "show me context around that time"
-  - Example: Search for "OAuth implementation" then get surrounding timeline
+## Search Parameters
 
-For detailed instructions on any operation, read the corresponding file in [operations/](operations/).
+**Basic:**
+- `query` - What to search for (required)
+- `format` - "index" or "full" (always use "index" first)
+- `limit` - How many results (default 5, max 100)
 
-## Quick Decision Guide
+**Filters (optional):**
+- `type` - Filter to "observations", "sessions", or "prompts"
+- `project` - Filter by project name
+- `dateRange[start]` - Start date (YYYY-MM-DD)
+- `dateRange[end]` - End date (YYYY-MM-DD)
+- `obs_type` - Filter observations by: bugfix, feature, decision, discovery, change
 
-**What is the user asking about?**
+## Examples
 
-1. **Recent work** (last 3-5 sessions) → Use **recent-context** with limit=3-5
-2. **Specific topic/keyword** (bugs, features, decisions) → Use **observations** search
-3. **Specific file history** (changes to a file) → Use **by-file** search
-4. **Timeline/chronology** (what happened when) → Use **timeline** or **timeline-by-query**
-5. **Type-specific** (all bug fixes, all features) → Use **by-type** filter
+**Find recent bug fixes:**
+```bash
+curl "http://localhost:37777/api/search?query=bug&type=observations&obs_type=bugfix&format=index&limit=5"
+```
 
-**Most common:** Use **observations** search for general "how did we..." questions.
+**Find what happened last week:**
+```bash
+curl "http://localhost:37777/api/search?query=&type=observations&dateRange[start]=2025-11-11&format=index&limit=10"
+```
 
-## Progressive Disclosure Workflow (Token Efficiency)
+**Search everything:**
+```bash
+curl "http://localhost:37777/api/search?query=database+migration&format=index&limit=5"
+```
 
-**Core Principle**: Find high-signal items in index format FIRST (~50-100 tokens each), then request full details ONLY for relevant items (~500-1000 tokens each).
+## Why This Workflow?
 
-**4-Step Workflow:**
+**Token efficiency:**
+- Index format: ~50-100 tokens per result
+- Full format: ~500-1000 tokens per result
+- **10x difference** - only fetch full when you know it's relevant
 
-1. **Start with Index Format**
-   - Always use `format=index` initially
-   - Set `limit=3-5` (not 10-20)
-   - Review titles and dates to assess relevance
-   - Token cost: ~50-100 per result
-
-2. **Identify Relevant Items**
-   - Scan index results
-   - Discard irrelevant items from list
-   - Keep only 1-3 most relevant
-
-3. **Request Full Details Selectively**
-   - Use `format=full` ONLY for specific relevant items
-   - Token cost: ~500-1000 per result
-   - **10x cost difference** - be selective
-
-4. **Refine with Filters**
-   - Use type, dateRange, concepts, files filters
-   - Paginate with offset if needed
-   - Narrow scope before expanding limits
-
-**DO:**
-- ✅ Start with `format=index` and `limit=3-5`
-- ✅ Use filters (type, dateRange, concepts, files) to narrow results
-- ✅ Request `format=full` ONLY for specific relevant items
-- ✅ Use offset for pagination instead of large limits
-
-**DON'T:**
-- ❌ Jump straight to `format=full`
-- ❌ Request `limit=20` without assessing index results first
-- ❌ Load full details for all results upfront
-- ❌ Skip index format to "save a step" (costs 10x more tokens)

-
-| Need | Operation | Key Parameters |
-|------|-----------|----------------|
-| Recent context | recent-context | limit=3-5 |
-| Search observations | observations | query, format=index, limit=5 |
-| Search sessions | sessions | query, format=index, limit=5 |
-| Find by type | by-type | type=(bugfix\|feature\|decision), format=index |
-| Find by file | by-file | filePath, format=index |
-| Timeline around event | timeline | anchor=(sessionDbId), depth_before=5, depth_after=5 |
-| Search + timeline | timeline-by-query | query, mode=auto |
-
-## Common Workflows
-
-For step-by-step guides on typical user requests, see [operations/common-workflows.md](operations/common-workflows.md):
-- Understanding past work from previous sessions
-- Finding specific bug fixes from history
-- Understanding file history across sessions
-- Timeline investigation workflows
-- Search composition patterns
-
-## Response Formatting
-
-For guidelines on presenting search results to users, see [operations/formatting.md](operations/formatting.md):
-- Index format responses (compact lists with titles/dates)
-- Full format responses (complete observation details)
-- Timeline responses (chronologically grouped)
-- Error handling and user-friendly messages
-
-## Technical Notes
-
-- **Port:** Default 37777 (configurable via `CLAUDE_MEM_WORKER_PORT`)
-- **Response format:** Always JSON
-- **Search engine:** ChromaDB semantic search (primary ranking) + SQLite FTS5 (fallback) + 90-day recency filter + temporal ordering (hybrid architecture)
-- **All operations:** HTTP GET with query parameters
-- **Worker:** PM2-managed background process
+**Clarity:**
+- See everything first
+- Pick what matters
+- Get details only for what you need
 
 ## Error Handling
 
-If HTTP request fails:
-1. Inform user the claude-mem search service isn't available
-2. Suggest checking if worker is running: `pm2 list` or `pm2 status claude-mem-worker`
-3. Offer to help troubleshoot using the troubleshoot skill

-**Remember:** This skill searches **cross-session persistent memory**, NOT current conversation. Start with index format for token efficiency. Use temporal triggers to differentiate from native Claude memory.
+**Remember:** ALWAYS search with format=index first. ALWAYS fetch by ID for details. The IDs are there for a reason - USE THEM.

+# Postmortem: Worker Debug Failure - 2025-11-17
+
+## Incident Summary
+Attempted to fix broken worker service. Worker was in crash loop with 225 restarts, failing with "MCP error -32000: Connection closed". Debug attempt failed and changes were reverted.
+
+## What Went Wrong
+
+### 1. **Jumped to Symptoms, Not Root Cause**
+- Saw "MCP connection failed" errors in logs
+- Immediately focused on MCP/Chroma connection code
+- Never asked: "Why is this suddenly broken when it worked before?"
+- Classic symptom chasing instead of root cause analysis
+
+### 2. **Ignored the Build Pipeline**
+- Worker file wasn't in the expected location (`plugin/worker-service.cjs` vs `plugin/scripts/worker-service.cjs`)
+- Build output existed but search server was producing corrupted/error output
+- Never investigated: "Is the build system broken?"
+- Should have compared built artifacts between main and current branch
+
+### 3. **Tried to Fix by Disabling Instead of Understanding**
+- Final approach: comment out Chroma, comment out search server
+- This is the opposite of debugging - it's just making things "work" by removing functionality
+- User called this out as "duct tape around 5 things unrelated to the problem"
+- Violated YAGNI/KISS by adding defensive complexity instead of fixing the actual issue
+
+### 4. **Didn't Compare Working vs Broken State**
+- User specifically said "we fixed this before"
+- Should have immediately: `git diff main src/services/worker-service.ts`
+- Did this eventually but didn't follow through on the findings
+- The diff showed only search-everything additions - the core worker code was UNCHANGED
+- This should have been a huge red flag: "If the code is the same, why is it broken?"
+
+### 5. **Overcomplicated the Investigation**
+- Started reading through ChromaSync implementation
+- Traced through MCP connection code
+- Analyzed startup sequences
+- All of this was unnecessary if the root cause was a build issue
+
+## What Should Have Happened
+
+### Correct Debug Sequence:
+1. ✅ Check worker status (`pm2 list`) - DONE
+2. ✅ Check error logs - DONE
+3. ❌ **Compare current code to main branch** - SKIPPED INITIALLY
+4. ❌ **Check if built files are correct** - SKIPPED
+5. ❌ **Test the build pipeline** - NEVER DONE
+6. ❌ **Verify dependencies are installed** - NEVER CHECKED
+
+### The Real Questions:
+- Is this a code change or a build issue?
+- What changed between working state and broken state?
+- Are the built artifacts corrupted?
+- Is the search server build actually valid?
+- Are there missing dependencies in plugin/scripts/node_modules?
+
+## Likely Root Causes (Untested)
+
+Based on evidence:
+1. **Build artifacts are corrupted** - search-server.mjs threw syntax errors when run
+2. **Node modules missing/outdated** - plugin/scripts/node_modules may be stale
+3. **ESM/CJS bundling issue** - esbuild may have produced invalid output
+4. **search-everything branch has broken build config** - scripts/build-hooks.js may have issues
+
+## Key Lessons
+
+### KISS/DRY/YAGNI Violations
+- Added complexity (disabling features) instead of removing it
+- Tried to work around symptoms instead of fixing root cause
+- Ignored the principle: "If it worked before and code is same, it's environment/build"
+
+### Debugging Anti-Patterns
+1. **Symptom Chasing**: Following error messages down rabbit holes
+2. **Defensive Coding**: Commenting out "broken" features instead of fixing them
+3. **Ignoring History**: Not comparing working vs broken states
+4. **Build Blindness**: Assuming built artifacts are correct without verification
+
+### What Good Debugging Looks Like
+1. Compare working state (main) vs broken state (current branch)
+2. Identify what actually changed (code? deps? build?)
+3. Test the simplest hypothesis first (build issue vs code issue)
+4. Never disable features to "fix" things - that's not fixing
+
+## Action Items for Next Attempt
+
+### Before Writing Any Code:
+- [ ] `git diff main` for all modified files
+- [ ] Check if `plugin/scripts/` artifacts are valid JavaScript
+- [ ] Compare build process: `npm run build` output on main vs current branch
+- [ ] Verify `plugin/scripts/node_modules` exists and is current
+- [ ] Test search-server.mjs in isolation: `node plugin/scripts/search-server.mjs`
+
+### If Build is Broken:
+- [ ] Check scripts/build-hooks.js for recent changes
+- [ ] Verify esbuild configuration
+- [ ] Test build on main branch, then on current branch
+- [ ] Don't modify source code until build is proven working
+
+### If Code is Broken:
+- [ ] Create minimal repro (which specific change broke it?)
+- [ ] Fix the actual bug, don't add workarounds
+- [ ] Test the fix in isolation
+
+## Conclusion
+
+This failure exemplifies "debugging by making changes" instead of "debugging by understanding". The instinct to fix symptoms (MCP errors) instead of investigating root cause (why is it broken now?) led to wasted effort and ultimately no solution.
+
+The user's frustration was justified - I was adding defensive duct tape instead of finding and fixing the real problem. This is exactly what KISS/DRY/YAGNI principles are meant to prevent.
+
+**Next time: Compare, verify, understand, THEN fix. Never disable features to make errors go away.**

+ Unified Search API Consolidation Plan
+
+ Overview
+
+ Consolidate 10 search endpoints into 6 powerful, semantic endpoints with intelligent aliasing for backward compatibility.
+
+ New Endpoint Structure
+
+ 1. /search - Unified Cross-Type Search
+
+ - Searches all record types (observations + sessions + prompts) via Chroma multi-collection search
+ - Optional type filter to narrow down
+ - Replaces: search_observations, search_sessions, search_user_prompts
+ - Params: query, response=[index|full], type, project, dateRange, limit, offset, orderBy
+
+ 2. /timeline - Unified Timeline Tool
+
+ - Supports both anchor-based and query-based modes via params
+ - If anchor → direct timeline lookup (like get_context_timeline)
+ - If query → search-first then timeline (like get_timeline_by_query)
+ - Params: anchor OR query, depth_before, depth_after, response, mode, project
+
+ 3. /decisions - Decision Observations
+
+ - Metadata-first search for type=decision observations
+ - Uses specialized search logic for precision
+ - Params: response, project, dateRange, limit, offset, orderBy
+
+ 4. /changes - Change Observations
+
+ - Metadata-first search for type=change observations
+ - Same pattern as /decisions
+
+ 5. /how-it-works - How-It-Works Concept
+
+ - Metadata-first search for concept=how-it-works observations
+ - Same pattern as concept endpoints
+
+ 6. /contextualize - Intelligent Context Builder
+
+ - Complex hybrid endpoint:
+   a. Get 7 latest decisions + 7 latest changes + 3 latest how-it-works
+   b. Find newest date across all results
+   c. Get timeline (7 before + 7 after) around that date
+   d. Merge & re-sort into single timeline (newest → oldest)
+   e. Return timeline + narratives of each concept's latest result
+ - Params: query (for contextualization), project
+
+ Implementation Phases
+
+ Phase 1: Core Unified Search (search-server.ts)
+
+ - Create search tool with Chroma multi-collection query
+ - Add type filtering support
+ - Alias old tools: search_observations → search(type=['observations'])
+
+ Phase 2: Unified Timeline (search-server.ts)
+
+ - Merge get_context_timeline + get_timeline_by_query logic
+ - Support both anchor and query params (mutually exclusive)
+ - Alias old timeline tools to new unified implementation
+
+ Phase 3: Specialized Concept Endpoints (search-server.ts)
+
+ - Create decisions, changes, how_it_works tools
+ - Use metadata-first search strategy
+ - Update find_by_type and find_by_concept to call these internally
+
+ Phase 4: Contextualize Endpoint (search-server.ts)
+
+ - Implement parallel fetching (7 decisions, 7 changes, 3 how-it-works)
+ - Find newest date, get timeline around it
+ - Merge, re-sort, extract narratives
+ - Return structured response with timeline + narratives
+
+ Phase 5: HTTP API Routes (worker-service.ts)
+
+ - Add 6 new routes: /api/search, /api/timeline, /api/decisions, /api/changes, /api/how-it-works, /api/contextualize
+ - Update old routes to alias new implementations
+ - Maintain backward compatibility
+
+ Phase 6: Chroma Multi-Collection Search (ChromaSync.ts)
+
+ - Add searchAll() method to query all collections in parallel
+ - Include source collection metadata in results
+ - Merge and rank by similarity score
+
+ Phase 7: SQLite Fallback (SessionSearch.ts)
+
+ - Add searchAll() for FTS5 fallback when Chroma unavailable
+ - Merge results from all three FTS5 tables
+
+ Phase 8: Documentation & Skill Updates
+
+ - Update mem-search skill with new endpoints
+ - Update CLAUDE.md and README.md
+ - Add examples and migration guide
+
+ Phase 9: Testing & Deployment
+
+ - Unit tests for all new tools
+ - Integration tests for aliasing
+ - Manual testing via mem-search skill
+ - Build → sync → worker restart
+
+ Key Design Decisions
+
+ ✅ Aliasing Strategy: Old endpoints call new implementations internally (zero breaking changes)
+ ✅ Unified Search: Chroma multi-collection search for true cross-type queries
+ ✅ Flexible Timeline: Single tool supports both direct and query-based modes
+ ✅ Specialized Shortcuts: /decisions, /changes, /how-it-works for common queries
+ ✅ Intelligent Context: /contextualize auto-builds rich context with narratives
+
+ Migration Impact
+
+ - Users: Zero breaking changes, old endpoints work via aliasing
+ - Codebase: Simplified from 10 conceptual endpoints to 6
+ - Performance: Improved via Chroma multi-collection search
+ - Developer UX: Cleaner, more semantic API
