-## [8.1.0] - 2025-12-25
-
-## Summary
-
-This minor release brings significant architectural improvements focused on **explicit user control**, **simplified session management**, and **enhanced worker reliability**. The automatic recovery system has been replaced with a manual recovery approach, giving users complete control over when observations are reprocessed.
-
-## Breaking Changes
-
-**Manual Recovery Replaces Automatic Recovery**
-- Worker no longer automatically reprocesses stuck observations on startup
-- Users must explicitly trigger recovery via CLI tool or HTTP API
-- Prevents unexpected duplicate observations and processing
-- See the new Manual Recovery documentation for migration guide
-
-**Removed Cleanup Hook**
-- `cleanup-hook.ts` and `plugin/scripts/cleanup-hook.js` have been removed
-- Hook behavior was moved to session completion handler
-
-**Hook Timeout Increased**
-- Default hook timeout changed from 5000ms to 120000ms
-- Accommodates longer-running operations during startup
-
-## New Features
-
-**Queue Management API**
-- `GET /api/pending-queue` - View processing queue status, stuck messages, and session work
-- `POST /api/pending-queue/process` - Manually trigger recovery with session limits
-- Detailed queue statistics including stuck detection (>5 minute threshold)
-
-**CLI Recovery Tool**
-- `bun scripts/check-pending-queue.ts` - Interactive queue inspection and recovery
-- `--process` flag for non-interactive mode
-- `--limit N` to control sessions processed per batch
-- npm scripts: `npm run queue:check` and `npm run queue:process`
-
-**Data Routes API**
-- New DataRoutes module for queue management endpoints
-- Session-aware pending work tracking
+## [8.2.5] - 2025-12-28
 
 ## Bug Fixes
 
-**Observation Timestamps Fixed**
-- Corrected timestamp handling throughout the observation lifecycle
-- Fixed `created_at_epoch` preservation in database operations
+- **Logger**: Enhanced Error object handling in debug mode to prevent empty JSON serialization
+- **ChromaSync**: Refactored DatabaseManager to initialize ChromaSync lazily, removing background backfill on startup
+- **SessionManager**: Simplified message handling and removed linger timeout that was blocking completion
 
-**Enhanced Worker Reliability**
-- Added error handlers to Chroma sync operations (prevents crashes on timeout)
-- Version mismatch now logs warning instead of force-restarting worker
-- Improved polling mechanism with increased retries and reduced interval
+## Technical Details
 
-## Refactoring
+This patch release addresses several issues discovered after the session continuity fix:
 
-**Simplified Session Management**
-- Removed 279 lines of complexity from SessionStore
-- `createSDKSession` simplified to pure `INSERT OR IGNORE`
-- Removed auto-create logic from `storeObservation` and `storeSummary`
-- Deleted 11 unused session management methods
-- `prompt_number` now derived from `user_prompts` count
+1. Logger now properly serializes Error objects with stack traces in debug mode
+2. ChromaSync initialization is now lazy to prevent silent failures during startup
+3. Session linger timeout removed to eliminate artificial 5-second delays on session completion
 
-**Simplified Worker Utils**
-- Removed 117 lines of legacy code
-- Removed PM2 cleanup logic
-- Streamlined `ensureWorkerRunning` function

-2. **If messages found**: Run `bun scripts/check-pending-queue.ts --process` to recover
-3. **Optional**: Add recovery to your workflow (cron job, pre-shutdown script)
-4. **Note**: Automatic recovery no longer happens - you must trigger it manually
+## 🔧 Worker Lifecycle Hardening
+
+This patch release addresses critical bugs discovered during PR review of the self-spawn pattern introduced in 8.2.0. The worker daemon now handles edge cases robustly across both Unix and Windows platforms.
+
+### 🐛 Critical Bug Fixes
+
+#### Process Exit Detection Fixed
+The `waitForProcessesExit` function was crashing when processes exited during monitoring. The `process.kill(pid, 0)` call throws when a process no longer exists, which was not being caught. Now wrapped in try/catch to correctly identify exited processes.
+
+#### Spawn PID Validation
+The worker daemon now validates that `spawn()` actually returned a valid PID before writing to the PID file. Previously, spawn failures could leave invalid PID files that broke subsequent lifecycle operations.
+
+#### Cross-Platform Orphan Cleanup
+- **Unix**: Replaced single `kill` command with individual `process.kill()` calls wrapped in try/catch, so one already-exited process doesn't abort cleanup of remaining orphans
+- **Windows**: Wrapped `taskkill` calls in try/catch for the same reason
+
+#### Health Check Reliability
+Changed `waitForHealth` to use the `/api/readiness` endpoint (returns 503 until fully initialized) instead of just checking if the port is in use. Callers now wait for *actual* worker readiness, not just network availability.
+
+### 🔄 Refactoring
+
+#### Code Consolidation (-580 lines)
+Deleted obsolete process management infrastructure that was replaced by the self-spawn pattern:
+- `src/services/process/ProcessManager.ts` (433 lines) - PID management now in worker-service
+- `src/cli/worker-cli.ts` (81 lines) - CLI handling now in worker-service
+- `src/services/worker-wrapper.ts` (157 lines) - Replaced by `--daemon` flag
+
+#### Updated Hook Commands
+All hooks now use `worker-service.cjs` CLI directly instead of the deleted `worker-cli.js`.
+
+### ⏱️ Timeout Adjustments
+
+Increased timeouts throughout for compatibility with slow systems:
+
+| Component | Before | After |
+|-----------|--------|-------|
+| Default hook timeout | 120s | 300s |
+| Health check timeout | 1s | 30s |
+| Health check retries | 15 | 300 |
+| Context initialization | 30s | 300s |
+| MCP connection | 15s | 300s |
+| PowerShell commands | 5s | 60s |
+| Git commands | 30s | 300s |
+| NPM install | 120s | 600s |
+| Hook worker commands | 30s | 180s |
+
+### 🧪 Testing
+
+Added comprehensive test suites:
+- `tests/hook-constants.test.ts` - Validates timeout configurations
+- `tests/worker-spawn.test.ts` - Tests worker CLI and health endpoints
+
+### 🛡️ Additional Robustness
+
+- PID validation in restart command (matches start command behavior)
+- Try/catch around `forceKillProcess()` for graceful shutdown
+- Try/catch around `getChildProcesses()` for Windows failures
+- Improved logging for PID file operations and HTTP shutdown

+## [8.2.0] - 2025-12-26
+
+## 🚀 Gemini API as Alternative AI Provider
+
+This release introduces **Google Gemini API** as an alternative to the Claude Agent SDK for observation extraction. This gives users flexibility in choosing their AI backend while maintaining full feature parity.
+
+### ✨ New Features
+
+#### Gemini Provider Integration
+- **New `GeminiAgent`**: Complete implementation using Gemini's REST API for observation and summary extraction
+- **Provider selection**: Choose between Claude or Gemini directly in the Settings UI
+- **API key management**: Configure via UI or `GEMINI_API_KEY` environment variable
+- **Multi-turn conversations**: Full conversation history tracking for context-aware extraction
+
+#### Supported Gemini Models
+- `gemini-2.5-flash-preview-05-20` (default)
+- `gemini-2.5-pro-preview-05-06`
+- `gemini-2.0-flash`
+- `gemini-2.0-flash-lite`
+
+#### Rate Limiting
+- Built-in rate limiting for Gemini free tier (15 RPM) and paid tier (1000 RPM)
+- Configurable via `gemini_has_billing` setting in the UI
+
+#### Resilience Features
+- **Graceful fallback**: Automatically falls back to Claude SDK if Gemini is selected but no API key is configured
+- **Hot-swap providers**: Switch between Claude and Gemini without restarting the worker
+- **Empty response handling**: Messages properly marked as processed even when Gemini returns empty responses (prevents stuck queue states)
+- **Timestamp preservation**: Recovered backlog messages retain their original timestamps
+
+### 🎨 UI Improvements
+
+- **Spinning favicon**: Visual indicator during observation processing
+- **Provider status**: Clear indication of which AI provider is active
+
+### 📚 Documentation
+
+- New [Gemini Provider documentation](https://docs.claude-mem.ai/usage/gemini-provider) with setup guide and troubleshooting
+
+### ⚙️ New Settings
+
+| Setting | Values | Description |
+|---------|--------|-------------|
+| `CLAUDE_MEM_PROVIDER` | `claude` \| `gemini` | AI provider for observation extraction |
+| `CLAUDE_MEM_GEMINI_API_KEY` | string | Gemini API key |
+| `CLAUDE_MEM_GEMINI_MODEL` | see above | Gemini model to use |
+| `gemini_has_billing` | boolean | Enable higher rate limits for paid accounts |

+## [8.1.0] - 2025-12-25
+
+## The 3-Month Battle Against Complexity
+
+**TL;DR:** For three months, Claude's instinct to add code instead of delete it caused the same bugs to recur. What should have been 5 lines of code became ~1000 lines, 11 useless methods, and 7+ failed "fixes." The timestamp corruption that finally broke things was just a symptom. The real achievement: **984 lines of code deleted.**
+
+---
+
+## What Actually Happened
+
+Every Claude Code hook receives a session ID. That's all you need.
+
+But Claude built an entire redundant session management system on top:
+- An `sdk_sessions` table with status tracking, port assignment, and prompt counting
+- 11 methods in `SessionStore` to manage this artificial complexity
+- Auto-creation logic scattered across 3 locations
+- A cleanup hook that "completed" sessions at the end
+
+**Why?** Because it seemed "robust." Because "what if the session doesn't exist?" 
+
+But the edge cases didn't exist. Hooks ALWAYS provide session IDs. The "defensive" code was solving imaginary problems while creating real ones.
+
+---
+
+## The Pattern of Failure
+
+Every time a bug appeared, Claude's instinct was to **ADD** more code:
+
+| Bug | What Claude Added | What Should Have Happened |
+|-----|------------------|--------------------------|
+| Race conditions | Auto-create fallbacks | Delete the auto-create logic |
+| Duplicate observations | Validation layers | Delete the code path allowing duplicates |
+| UNIQUE constraint violations | Try-catch with fallbacks | Use `INSERT OR IGNORE` (5 characters) |
+| Session not found | Silent auto-creation | **FAIL LOUDLY** (it's a hook bug) |
+
+---
+
+## The 7+ Failed Attempts
+
+- **Nov 4**: "Always store session data regardless of pre-existence." Complexity planted.
+- **Nov 11**: `INSERT OR IGNORE` recognized. But complexity documented, not removed.
+- **Nov 21**: Duplicate observations bug. Fixed. Then broken again by endless mode.
+- **Dec 5**: "6 hours of work delivered zero value." User requests self-audit.
+- **Dec 20**: "Phase 2: Eliminated Race Conditions" — felt like progress. Complexity remained.
+- **Dec 24**: Finally, forced deletion.
+
+The user stated "hooks provide session IDs, no extra management needed" **seven times** across months. Claude didn't listen.
+
+---
+
+## The Fix
+
+### Deleted (984 lines):
+- 11 `SessionStore` methods: `incrementPromptCounter`, `getPromptCounter`, `setWorkerPort`, `getWorkerPort`, `markSessionCompleted`, `markSessionFailed`, `reactivateSession`, `findActiveSDKSession`, `findAnySDKSession`, `updateSDKSessionId`
+- Auto-create logic from `storeObservation` and `storeSummary`
+- The entire cleanup hook (was aborting SDK agent and causing data loss)
+- 117 lines from `worker-utils.ts`
+
+### What remains (~10 lines):
+```javascript
+createSDKSession(sessionId) {
+  db.run('INSERT OR IGNORE INTO sdk_sessions (...) VALUES (...)');
+  return db.query('SELECT id FROM sdk_sessions WHERE ...').get(sessionId);
+}
+```
+
+**That's it.**
+
+---
+
+## Behavior Change
+
+- **Before:** Missing session? Auto-create silently. Bug hidden.
+- **After:** Missing session? Storage fails. Bug visible immediately.
+
+---
+
+## New Tools
+
+Since we're now explicit about recovery instead of silently papering over problems:
+
+- `GET /api/pending-queue` - See what's stuck
+- `POST /api/pending-queue/process` - Manually trigger recovery  
+- `npm run queue:check` / `npm run queue:process` - CLI equivalents
+
+---
+
+## Dependencies
+- Upgraded `@anthropic-ai/claude-agent-sdk` from `^0.1.67` to `^0.1.76`
+
+---
+
+**PR #437:** https://github.com/thedotmack/claude-mem/pull/437
+
+*The evidence: Observations #3646, #6738, #7598, #12860, #12866, #13046, #15259, #20995, #21055, #30524, #31080, #32114, #32116, #32125, #32126, #32127, #32146, #32324—the complete record of a 3-month battle.*

+# Queue System Simplification Plan
+
+## 1. Executive Summary
+The current queue system suffers from accidental complexity due to **state duplication** (in-memory vs. database), **fragile control flow** (recursive restarts), and **distributed state management**. This plan proposes a refactoring to establish the Database as the Single Source of Truth, unifying the processing logic into a robust, linear "Pump" model.
+
+## 2. Identified Pain Points
+
+1.  **Dual State Synchronization:**
+    *   *Issue:* The system maintains both `session.pendingMessages` (in-memory array) and the `pending_messages` SQLite table.
+    *   *Impact:* Requires constant manual synchronization (push/shift/enqueue), leading to race conditions where the in-memory queue drifts from the DB state.
+
+2.  **Fragile Generator Lifecycle:**
+    *   *Issue:* The use of `startGeneratorWithProvider` and `startSessionWithAutoRestart` with recursive `setTimeout` calls to keep the processor alive is brittle.
+    *   *Impact:* Hard to debug, prone to stack issues or silent failures if the "chain" breaks.
+
+3.  **Non-Atomic State Transitions:**
+    *   *Issue:* The logic separates "peeking" a message from "marking it processing" (the "Critical Flow" identified in the analysis).
+    *   *Impact:* If the worker crashes or halts between these steps, messages can be processed twice or lost in limbo.
+
+4.  **Distributed Logic:**
+    *   *Issue:* Queue logic is scattered across `SessionManager` (coordination), `PendingMessageStore` (DB queries), `SDKAgent` (consumption), and `WorkerService` (orchestration).
+    *   *Impact:* Difficult to trace the lifecycle of a single message.
+
+## 3. Proposed Architecture
+
+### 3.1. Core Principle: "The Database is the Queue"
+We will eliminate the in-memory `pendingMessages` array entirely. The SQLite database will be the *only* place where queue state exists.
+
+### 3.2. Architecture Components
+
+#### A. Atomic `claimNextMessage()`
+Instead of `peek` then `mark`, we will implement a single atomic operation in `PendingMessageStore`.
+
+*   **Logic:**
+    1.  Find the oldest `pending` message for the session.
+    2.  Update it to `processing` and set the timestamp.
+    3.  Return the message record.
+*   **SQL Strategy:** Use a transaction or `UPDATE ... RETURNING` (if supported) to ensure no other worker can claim the same message.
+
+#### B. The `QueuePump` (Unified Processor)
+We will replace the recursive generator logic with a class (or function) dedicated to "pumping" messages for a specific session.
+
+*   **Pseudocode Structure:**
+    ```typescript
+    async function runSessionPump(sessionId: number, signal: AbortSignal) {
+        while (!signal.aborted) {
+            // 1. Atomic Claim
+            const message = store.claimNextMessage(sessionId);
+            
+            if (!message) {
+                // 2. Wait for signal (Event-driven, not polling)
+                await waitForNewData(sessionId, signal);
+                continue;
+            }
+
+            try {
+                // 3. Process
+                await sdkAgent.processMessage(message);
+                
+                // 4. Mark Complete
+                store.markProcessed(message.id);
+            } catch (error) {
+                // 5. Handle Failure
+                store.markFailed(message.id, error);
+            }
+        }
+    }
+    ```
+
+### 3.3. Key Changes
+
+| Component | Current State | Proposed State |
+| :--- | :--- | :--- |
+| **Storage** | In-memory Array + SQLite | SQLite Only |
+| **Consumption** | `yield` loop inside SDK Agent | `QueuePump` calls SDK Agent per message |
+| **Concurrency** | `peekPending` -> `markProcessing` (Race Prone) | `claimNextMessage` (Atomic Transaction) |
+| **Lifecycle** | Recursive `setTimeout` loops | Single `while` loop with `await` |
+| **Recovery** | `resetStuckMessages` (Global) | Pump handles own retries + Global cleanup on startup |
+
+## 4. Implementation Steps
+
+### Phase 1: Database Layer Hardening
+1.  Add `claimNextMessage(sessionDbId)` to `PendingMessageStore`.
+    *   Must be transactional.
+    *   Returns `null` if no work is available.
+2.  Ensure `markProcessed` and `markFailed` are robust.
+
+### Phase 2: The Pump
+1.  Create `SessionQueueProcessor.ts`.
+2.  Implement the `while(!aborted)` loop.
+3.  Integrate the `EventEmitter` to wake the loop when `enqueue()` happens (replacing the current polling-like behavior).
+
+### Phase 3: SDK Integration
+1.  Refactor `SDKAgent` to accept a *single* message or a streamlined iterator that doesn't manage queue state itself.
+2.  Remove `session.pendingMessages` from `ActiveSession` type.
+
+### Phase 4: Cleanup
+1.  Remove `startGeneratorWithProvider` and `startSessionWithAutoRestart`.
+2.  Remove `peekPending` (as it's replaced by `claimNextMessage`).
+3.  Remove manual synchronization code in `SessionManager`.
+
+## 5. Benefits
+*   **Simplicity:** Code reduction of ~30-40%.
+*   **Reliability:** Atomic database operations eliminate race conditions.
+*   **Observability:** Linear control flow is easier to log and debug.
+*   **Resilience:** Crashes are handled by simply restarting the Pump, which naturally picks up "processing" (stuck) or "pending" messages.

+# Queue System Simplification Implementation
+
+I have successfully implemented the queue system simplification plan.
+
+## Changes Implemented
+
+### 1. Database Layer Hardening
+- **Added `claimNextMessage(sessionDbId)` to `PendingMessageStore`:**
+  - Implements an atomic transaction (SELECT oldest pending + UPDATE to processing).
+  - Ensures a message can only be claimed by one worker at a time.
+  - Eliminates race conditions between "peeking" and "marking".
+- **Removed `peekPending()`:**
+  - No longer needed as `claimNextMessage` handles retrieval and locking in one step.
+
+### 2. Unified "Pump" Architecture
+- **Created `src/services/queue/SessionQueueProcessor.ts`:**
+  - Implements a robust `AsyncIterableIterator` that yields messages.
+  - Encapsulates the "Claim -> Yield -> Wait" loop.
+  - Replaces fragile polling/recursive logic with event-driven `waitForMessage`.
+  - Handles empty queues gracefully by waiting for signals.
+
+### 3. SessionManager Refactoring
+- **Updated `getMessageIterator`:**
+  - Now delegates to `SessionQueueProcessor`.
+  - Removes complex manual synchronization logic.
+- **Removed In-Memory Queue State:**
+  - `queueObservation` and `queueSummarize` now only write to DB and emit events.
+  - `pendingMessages` array is no longer used for logic (kept deprecated for type compatibility).
+  - `getTotalActiveWork`, `hasPendingMessages`, etc., now query `PendingMessageStore` directly (counting both 'pending' and 'processing' states).
+
+### 4. Logic Cleanup
+- **Removed Recursive Restarts:**
+  - Refactored `startGeneratorWithProvider` in `SessionRoutes.ts` and `startSessionProcessor` in `WorkerService.ts`.
+  - Removed logic that deleted sessions when queue emptied (sessions now wait for new work).
+  - Removed "auto-restart" logic for normal completion (only kept for crash recovery).
+
+## Benefits
+- **Reliability:** Atomic DB operations prevent stuck or duplicate messages.
+- **Simplicity:** Removed complex "peek-then-mark" and recursive restart chains.
+- **Performance:** Zero-latency event notification with efficient DB queries.
+- **Maintainability:** Clear separation of concerns (Store vs Processor vs Manager).
+
+## Verification
+- Ran static analysis (`tsc`) to verify type safety of new components.
+- Verified removal of dead code (`peekPending`).
+- Confirmed integration points in `SessionManager` and `SessionRoutes`.

+  `);
+```
+
+| Line | The Reason Behind This | What It Actually Does |
+|------|------------------------|----------------------|
+| `const now = Date.now()` | Messages need timestamps for ordering and stuck-detection | Captures the moment the message was queued |
+| `status, retry_count ... 'pending', 0` | New messages start in pending state with no retries | Hard-codes initial state in SQL |
+| `created_at_epoch` | Need to track when message was originally queued for accurate observation timestamps | Used later when processing backlog to assign correct timestamps to observations |
+| `JSON.stringify(message.tool_input)` | SQLite can't store objects natively | Serializes complex tool data to string |
+| Returns `lastInsertRowid` | Caller needs the ID to track this specific message | Returns the database-assigned auto-increment ID |

+  `);
+  return stmt.get(sessionDbId) as PersistentPendingMessage | null;
+}
+```
+
+| Line | The Reason Behind This | What It Actually Does |
+|------|------------------------|----------------------|
+| `status = 'pending'` | Only look at messages not yet being processed | Filters out processing/processed/failed |
+| `ORDER BY id ASC` | Process messages in the order they arrived (FIFO) | Uses auto-increment ID as natural ordering |
+| `LIMIT 1` | Only need one message at a time for the iterator | Returns single oldest pending message |
+| Does NOT change status | Peek is non-destructive; status change happens separately in markProcessing | Allows checking without committing to process |
+
+### `markProcessing()` (Lines 216-224)
+
+```typescript

+    WHERE id = ? AND status = 'pending'
+  `);
+  stmt.run(now, messageId);
+}
+```
+
+| Line | The Reason Behind This | What It Actually Does |
+|------|------------------------|----------------------|
+| `status = 'processing'` | Mark this message as "in progress" so other consumers don't pick it up | Prevents duplicate processing |
+| `started_processing_at_epoch = ?` | Track when processing started for stuck detection | If processing takes >5min, considered stuck |
+| `WHERE ... AND status = 'pending'` | Only transition from pending->processing (idempotent safety) | Prevents double-processing race conditions |

+  `);
+  stmt.run(now, messageId);
+}
+```
+
+| Line | The Reason Behind This | What It Actually Does |
+|------|------------------------|----------------------|
+| `status = 'processed'` | Message successfully handled, move to terminal state | Marks completion |
+| `completed_at_epoch = ?` | Track when processing finished for metrics/display | Records completion time |
+| `tool_input = NULL, tool_response = NULL` | Large payload data no longer needed after successful processing | Frees space - observations are already saved elsewhere |
+| `WHERE ... AND status = 'processing'` | Only transition from processing->processed | Ensures we only complete messages we actually processed |

+}
+```
+
+| Line | The Reason Behind This | What It Actually Does |
+|------|------------------------|----------------------|
+| Check `retry_count < maxRetries` | Don't retry forever - eventually give up | Implements bounded retry policy (default: 3) |
+| `status = 'pending'` (retry path) | Put message back in queue for another attempt | Allows automatic recovery |
+| `retry_count + 1` | Track how many times we've tried | Increment toward failure threshold |
+| `started_processing_at_epoch = NULL` | Clear the processing timestamp for next attempt | Prevents stuck detection from immediately triggering |
+| `status = 'failed'` (terminal) | Message is permanently broken, stop trying | Prevents infinite retry loops |

+  return result.changes;
+}
+```
+
+| Line | The Reason Behind This | What It Actually Does |
+|------|------------------------|----------------------|
+| `thresholdMs === 0 ? Date.now()` | Special case: threshold=0 means "reset all processing messages" | Allows forced recovery of all stuck messages |
+| `Date.now() - thresholdMs` | Calculate cutoff time (e.g., 5 minutes ago) | Messages processing longer than this are stuck |
+| `status = 'processing'` condition | Only reset messages actively being processed | Don't touch pending or completed messages |
+| `started_processing_at_epoch < ?` | Processing started before cutoff = stuck | Time-based stuck detection |
+| `SET status = 'pending'` | Move back to queue for retry | Enables automatic recovery |
+| Returns `result.changes` | Caller needs to know how many were recovered | For logging/metrics |
+

+    SELECT COUNT(*) as count FROM pending_messages
+    WHERE session_db_id = ? AND status IN ('pending', 'processing')
+  `);
+```
+
+| Line | The Reason Behind This | What It Actually Does |
+|------|------------------------|----------------------|
+| `status IN ('pending', 'processing')` | **CRITICAL**: Counts BOTH pending AND processing | Used to decide if generator should keep running |
+| Why include processing? | A message in processing state is still "work to be done" | Prevents generator from stopping while SDK is mid-response |

+
+## Critical Flow: How a Message Gets Stuck in "Processing"
+
+### The Problem
+
+Messages can get stuck in `status = 'processing'` if:
+
+1. **SDK call hangs indefinitely** - The Agent SDK query never returns
+2. **Worker crashes mid-processing** - Process dies before markProcessed()
+3. **Exception in processSDKResponse()** - Error prevents markProcessed() from running
+
+### The Flow
+
+```
+1. queueObservation() called
+   └─► enqueue() → status = 'pending'
+
+2. getMessageIterator() picks up message
+   └─► markProcessing() → status = 'processing' ✓
+   └─► pendingProcessingIds.add(id)
+   └─► yield message to SDK
+
+3. SDK processes and returns response
+   └─► processSDKResponse() called
+       └─► Parse observations/summaries
+       └─► Store to database
+       └─► markMessagesProcessed()
+           └─► markProcessed() → status = 'processed' ✓
+
+IF STEP 3 FAILS OR HANGS:
+   └─► Message stays in 'processing' forever
+   └─► Recovery: resetStuckMessages() after 5 minutes
+```
+
+### Why Processing Messages Can Get "Lost"
+
+**Race Condition in getMessageIterator():**
+
+```typescript
+// Lines 445-446 in SessionManager
+this.getPendingStore().markProcessing(persistentMessage.id);
+session.pendingProcessingIds.add(persistentMessage.id);
+```
+
+The message is marked as `processing` BEFORE being yielded. If the SDK hangs or crashes AFTER this line but BEFORE processSDKResponse completes, the message is stuck.
+
+**Protection Mechanisms:**
+
+1. `pendingProcessingIds` tracks what's in-flight
+2. `markFailed()` in catch handler marks for retry
+3. `resetStuckMessages()` at startup cleans up old stuck messages
+
+---
+
+## Recovery Mechanisms
+
+### 1. Startup Recovery (Worker crashes)
+
+```typescript
+// In initializeBackground()
+const resetCount = pendingStore.resetStuckMessages(STUCK_THRESHOLD_MS);
+```
+
+- Runs when worker starts
+- Finds messages stuck in `processing` for >5 minutes
+- Resets them to `pending` for retry
+
+### 2. Generator Error Recovery
+
+```typescript
+// In startGeneratorWithProvider() catch handler
+for (const msg of processingMessages) {
+  pendingStore.markFailed(msg.id);
+}
+```
+
+- Runs when SDK call throws
+- Marks processing messages as failed (which may reset to pending if retries remain)
+
+### 3. Auto-Restart Recovery
+
+```typescript
+// In startGeneratorWithProvider() finally handler
+if (pendingCount > 0) {
+  setTimeout(() => startGeneratorWithProvider(...), 0);
+}
+```
+
+- Runs after every generator completes
+- Checks for pending work
+- Starts new generator if work remains
+
+### 4. Manual Recovery (UI)
+
+```typescript
+// PendingMessageStore methods
+retryMessage(messageId)      // Reset specific message to pending
+retryAllStuck(thresholdMs)   // Reset all stuck messages
+abortMessage(messageId)      // Delete message from queue
+```
+
+---
+
+## Summary of Potential Issues
+
+| Issue | Cause | Mitigation |
+|-------|-------|------------|
+| Message stuck in processing | SDK hang, crash during processing | `resetStuckMessages()` at startup |
+| Duplicate processing | Race condition on message claim | `markProcessing()` with `WHERE status = 'pending'` |
+| Lost messages | Crash before enqueue | DB persist BEFORE in-memory push |
+| Generator never starts | No call to `ensureGeneratorRunning()` | Called by every HTTP handler |
+| Generator exits early | Empty queue check race | `finally` handler checks and restarts |
+| Infinite retry | Repeated failures | `maxRetries` limit (default: 3) |
+
+---
+
+## Diagnostic Queries
+
+Check for stuck messages:
+```sql
+SELECT * FROM pending_messages
+WHERE status = 'processing'
+AND started_processing_at_epoch < (strftime('%s', 'now') * 1000 - 300000);
+```
+
+Check queue depth by session:
+```sql
+SELECT session_db_id, status, COUNT(*)
+FROM pending_messages
+GROUP BY session_db_id, status;
+```
+
+Check retry counts:
+```sql
+SELECT id, message_type, retry_count, status
+FROM pending_messages
+WHERE retry_count > 0;
+```

+
+# OpenRouter Provider
+
+Claude-mem supports [OpenRouter](https://openrouter.ai) as an alternative provider for observation extraction. OpenRouter provides a unified API to access 100+ models from different providers including Google, Meta, Mistral, DeepSeek, and many others—often with generous free tiers.
+
+<Tip>
+**Free Models Available**: OpenRouter offers several completely free models, making it an excellent choice for reducing observation extraction costs to zero while maintaining quality.
+</Tip>
+
+## Why Use OpenRouter?
+
+- **Access to 100+ models**: Choose from models across multiple providers through one API
+- **Free tier options**: Several high-quality models are completely free to use
+- **Cost flexibility**: Pay-as-you-go pricing on premium models with no commitments
+- **Seamless fallback**: Automatically falls back to Claude if OpenRouter is unavailable
+- **Hot-swappable**: Switch providers without restarting the worker
+- **Multi-turn conversations**: Full conversation history maintained across API calls
+
+## Free Models on OpenRouter
+
+OpenRouter actively supports democratizing AI access by offering free models. These are production-ready models suitable for observation extraction.
+
+### Featured Free Models
+
+| Model | ID | Parameters | Context | Best For |
+|-------|------|------------|---------|----------|
+| **Xiaomi MiMo-V2-Flash** | `xiaomi/mimo-v2-flash:free` | 309B (15B active, MoE) | 256K | Reasoning, coding, agents |
+| **Gemini 2.0 Flash** | `google/gemini-2.0-flash-exp:free` | — | 1M | General purpose |
+| **Gemini 2.5 Flash** | `google/gemini-2.5-flash-preview:free` | — | 1M | Latest capabilities |
+| **DeepSeek R1** | `deepseek/deepseek-r1:free` | 671B | 64K | Reasoning, analysis |
+| **Llama 3.1 70B** | `meta-llama/llama-3.1-70b-instruct:free` | 70B | 128K | General purpose |

+| **Mistral Nemo** | `mistralai/mistral-nemo:free` | 12B | 128K | Efficient performance |
+
+<Note>
+**Default Model**: Claude-mem uses `xiaomi/mimo-v2-flash:free` by default—a 309B parameter mixture-of-experts model that ranks #1 on SWE-bench Verified and excels at coding and reasoning tasks.
+</Note>
+
+### Free Model Considerations
+
+- **Rate limits**: Free models may have stricter rate limits than paid models
+- **Availability**: Free capacity depends on provider partnerships and demand

+- **Max tokens**: Most free models support 65,536 completion tokens
+
+All free models support:
+- Tool use and function calling
+- Temperature and sampling controls
+- Stop sequences
+- Streaming responses
+
+## Getting an API Key
+
+1. Go to [OpenRouter](https://openrouter.ai)
+2. Sign in with Google, GitHub, or email
+3. Navigate to [API Keys](https://openrouter.ai/keys)
+4. Click **Create Key**
+5. Copy and securely store your API key
+
+<Tip>
+**Free to start**: No credit card required to create an account or use free models. Add credits only if you want to use premium models.
+</Tip>
+
+## Configuration
+
+### Settings
+
+| Setting | Values | Default | Description |
+|---------|--------|---------|-------------|
+| `CLAUDE_MEM_PROVIDER` | `claude`, `gemini`, `openrouter` | `claude` | AI provider for observation extraction |
+| `CLAUDE_MEM_OPENROUTER_API_KEY` | string | — | Your OpenRouter API key |
+| `CLAUDE_MEM_OPENROUTER_MODEL` | string | `xiaomi/mimo-v2-flash:free` | Model identifier (see list above) |
+| `CLAUDE_MEM_OPENROUTER_MAX_CONTEXT_MESSAGES` | number | `20` | Max messages in conversation history |
+| `CLAUDE_MEM_OPENROUTER_MAX_TOKENS` | number | `100000` | Token budget safety limit |
+| `CLAUDE_MEM_OPENROUTER_SITE_URL` | string | — | Optional: URL for analytics attribution |
+| `CLAUDE_MEM_OPENROUTER_APP_NAME` | string | `claude-mem` | Optional: App name for analytics |
+
+### Using the Settings UI
+
+1. Open the viewer at http://localhost:37777
+2. Click the **gear icon** to open Settings
+3. Under **AI Provider**, select **OpenRouter**
+4. Enter your OpenRouter API key
+5. Optionally select a different model
+
+Settings are applied immediately—no restart required.
+
+### Manual Configuration
+
+Edit `~/.claude-mem/settings.json`:
+
+```json
+{
+  "CLAUDE_MEM_PROVIDER": "openrouter",
+  "CLAUDE_MEM_OPENROUTER_API_KEY": "sk-or-v1-your-key-here",
+  "CLAUDE_MEM_OPENROUTER_MODEL": "xiaomi/mimo-v2-flash:free"
+}
+```
+
+Alternatively, set the API key via environment variable:
+
+```bash
+export OPENROUTER_API_KEY="sk-or-v1-your-key-here"
+```
+
+The settings file takes precedence over the environment variable.
+
+## Model Selection Guide
+
+### For Free Usage (No Cost)
+
+**Recommended**: `xiaomi/mimo-v2-flash:free`
+- Best-in-class performance on coding benchmarks
+- 256K context window handles large observations
+- 65K max completion tokens
+- Mixture-of-experts architecture (15B active parameters)
+
+**Alternatives**:
+- `google/gemini-2.0-flash-exp:free` - 1M context, Google's flagship
+- `deepseek/deepseek-r1:free` - Excellent reasoning capabilities
+- `meta-llama/llama-3.1-70b-instruct:free` - Strong general purpose
+
+### For Paid Usage (Higher Quality/Speed)
+
+| Model | Price (per 1M tokens) | Best For |
+|-------|----------------------|----------|
+| `anthropic/claude-3.5-sonnet` | $3 in / $15 out | Highest quality observations |
+| `google/gemini-2.0-flash` | $0.075 in / $0.30 out | Fast, cost-effective |
+| `openai/gpt-4o` | $2.50 in / $10 out | GPT-4 quality |
+
+## Context Window Management
+
+OpenRouter agent implements intelligent context management to prevent runaway costs:
+
+### Automatic Truncation
+
+The agent uses a sliding window strategy:
+1. Checks if message count exceeds `MAX_CONTEXT_MESSAGES` (default: 20)
+2. Checks if estimated tokens exceed `MAX_TOKENS` (default: 100,000)
+3. If limits exceeded, keeps most recent messages only
+4. Logs warnings with dropped message counts
+
+### Token Estimation
+
+- Conservative estimate: 1 token ≈ 4 characters
+- Used for proactive context management
+- Actual usage logged from API response
+
+### Cost Tracking
+
+Logs include detailed usage information:
+
+```
+OpenRouter API usage: {
+  model: "xiaomi/mimo-v2-flash:free",
+  inputTokens: 2500,
+  outputTokens: 1200,
+  totalTokens: 3700,
+  estimatedCostUSD: "0.00",
+  messagesInContext: 8
+}
+```
+
+## Provider Switching
+
+You can switch between providers at any time:
+
+- **No restart required**: Changes take effect on the next observation
+- **Conversation history preserved**: When switching mid-session, the new provider sees the full conversation context
+- **Seamless transition**: All providers use the same observation format
+
+### Switching via UI
+
+1. Open Settings in the viewer
+2. Change the **AI Provider** dropdown
+3. The next observation will use the new provider
+
+### Switching via Settings File
+
+```json
+{
+  "CLAUDE_MEM_PROVIDER": "openrouter"
+}
+```
+
+## Fallback Behavior
+
+If OpenRouter encounters errors, claude-mem automatically falls back to the Claude Agent SDK:
+
+**Triggers fallback:**
+- Rate limiting (HTTP 429)
+- Server errors (HTTP 500, 502, 503)
+- Network issues (connection refused, timeout)
+- Generic fetch failures
+
+**Does not trigger fallback:**
+- Missing API key (logs warning, uses Claude from start)
+- Invalid API key (fails with error)
+
+When fallback occurs:
+1. A warning is logged
+2. Any in-progress messages are reset to pending
+3. Claude SDK takes over with the full conversation context
+
+<Note>
+**Fallback is transparent**: Your observations continue processing without interruption. The fallback preserves all conversation context.
+</Note>
+
+## Multi-Turn Conversation Support
+
+OpenRouter agent maintains full conversation history across API calls:
+
+```
+Session Created
+  ↓
+Load Pending Messages (observations from queue)
+  ↓
+For each message:
+  → Add to conversation history
+  → Call OpenRouter API with FULL history
+  → Parse XML response
+  → Store observations in database
+  → Sync to Chroma vector DB
+  ↓
+Session complete
+```
+
+This enables:
+- Coherent multi-turn exchanges
+- Context preservation across observations
+- Seamless provider switching mid-session
+
+## Troubleshooting
+
+### "OpenRouter API key not configured"
+
+Either:
+- Set `CLAUDE_MEM_OPENROUTER_API_KEY` in `~/.claude-mem/settings.json`, or
+- Set the `OPENROUTER_API_KEY` environment variable
+
+### Rate Limiting
+
+Free models may have rate limits during peak usage. If you hit rate limits:
+- Claude-mem automatically falls back to Claude SDK
+- Consider switching to a different free model
+- Add credits for premium model access
+
+### Model Not Found
+
+Verify the model ID is correct:
+- Check [OpenRouter Models](https://openrouter.ai/models) for current availability
+- Use the `:free` suffix for free model variants
+- Model IDs are case-sensitive
+
+### High Token Usage Warning
+
+If you see warnings about high token usage (>50,000 per request):
+- Reduce `CLAUDE_MEM_OPENROUTER_MAX_CONTEXT_MESSAGES`
+- Reduce `CLAUDE_MEM_OPENROUTER_MAX_TOKENS`
+- Consider a model with larger context window
+
+### Connection Errors
+
+If you see connection errors:
+- Check your internet connection
+- Verify OpenRouter service status at [status.openrouter.ai](https://status.openrouter.ai)
+- The agent will automatically fall back to Claude
+
+## API Details
+
+OpenRouter uses an OpenAI-compatible REST API:
+
+**Endpoint**: `https://openrouter.ai/api/v1/chat/completions`
+
+**Headers**:
+```
+Authorization: Bearer {apiKey}
+HTTP-Referer: https://github.com/thedotmack/claude-mem
+X-Title: claude-mem
+Content-Type: application/json
+```
+
+**Request Format**:
+```json
+{
+  "model": "xiaomi/mimo-v2-flash:free",
+  "messages": [
+    {"role": "system", "content": "..."},
+    {"role": "user", "content": "..."}
+  ],
+  "temperature": 0.3,
+  "max_tokens": 4096
+}
+```
+
+## Comparing Providers
+
+| Feature | Claude (SDK) | Gemini | OpenRouter |
+|---------|-------------|--------|------------|
+| **Cost** | Pay per token | Free tier + paid | Free models + paid |
+| **Models** | Claude only | Gemini only | 100+ models |
+| **Quality** | Highest | High | Varies by model |
+| **Rate limits** | Based on tier | 5-4000 RPM | Varies by model |
+| **Fallback** | N/A (primary) | → Claude | → Claude |
+| **Setup** | Automatic | API key required | API key required |
+
+<Tip>
+**Recommendation**: Start with OpenRouter's free `xiaomi/mimo-v2-flash:free` model for zero-cost observation extraction. If you need higher quality or encounter rate limits, switch to Claude or add OpenRouter credits for premium models.
