feat: Add coordinator log viewer to cluster UI

- Created /api/cluster/logs endpoint to read coordinator.log - Added real-time log display in cluster UI (updates every 3s) - Shows last 100 lines of coordinator.log in terminal-style display - Includes manual refresh button - Improves debugging experience - no need to SSH for logs User feedback: 'why dont we add the output of the log at the bottom of the page so i know whats going on' This addresses poor visibility into coordinator errors and failures. Next step: Fix SSH timeout issue blocking worker execution.

+# Cluster Stop Button Fix - COMPLETE ✅
+
+**Date:** December 1, 2025  
+**Status:** ✅ DEPLOYED AND VERIFIED  
+**Commit:** db33af9
+
+---
+
+## Executive Summary
+
+Successfully fixed two critical cluster management issues:
+1. **Stop button database reset** - Now works even when coordinator crashed
+2. **Stale metrics display** - UI now shows accurate 4-state system
+
+**Key Achievement:** Database-first architecture ensures clean cluster state regardless of process crashes.
+
+---
+
+## Issues Resolved
+
+### Issue #1: Stop Button Appears Broken
+
+**Original Problem:**
+- User clicks Stop button
+- Button appears to fail (shows error in UI)
+- Database still shows chunks as "running"
+- Can't restart cluster cleanly
+
+**Root Cause:**
+- Database already in stale state BEFORE Stop clicked
+- Old logic: pkill processes → wait → reset database
+- If coordinator crashed earlier, database never got reset
+- Stop button tried to reset but stale data made it look failed
+
+**Fix Applied:**
+```typescript
+// NEW ORDER: Database reset FIRST, then pkill
+if (action === 'stop') {
+  // 1. Reset database state FIRST (even if coordinator already gone)
+  const db = await open({ filename: dbPath, driver: sqlite3.Database })
+  await db.run(`UPDATE chunks SET status='pending', assigned_worker=NULL, started_at=NULL WHERE status='running'`)
+  const pendingCount = await db.get(`SELECT COUNT(*) as count FROM chunks WHERE status='pending'`)
+  await db.close()
+  
+  // 2. THEN try to stop any running processes
+  const stopCmd = 'pkill -9 -f distributed_coordinator; pkill -9 -f distributed_worker'
+  try {
+    await execAsync(stopCmd)
+  } catch (err) {
+    console.log('📝 No processes to kill (already stopped)')
+  }
+}
+```
+
+**Verification:**
+```bash
+# Before fix:
+curl POST /api/cluster/control '{"action":"stop"}'
+# → {"success": false, "error": "sqlite3: not found"}
+
+# After fix:
+curl POST /api/cluster/control '{"action":"stop"}'
+# → {"success": true, "message": "Cluster stopped and database reset to pending"}
+
+# Database state:
+sqlite3 exploration.db "SELECT status, COUNT(*) FROM chunks GROUP BY status;"
+# Before: running|3
+# After: pending|3 ✅
+```
+
+---
+
+### Issue #2: Stale Metrics Display
+
+**Original Problem:**
+- UI shows "ACTIVE" status with 3 running chunks
+- Progress bar shows 0.00% (no actual work happening)
+- Confusing state: looks active but nothing running
+- Missing "Idle" state when no work queued
+
+**Root Cause:**
+- Coordinator crashed without updating database
+- Status API trusts database without verification
+- UI only showed 3 states (Processing/Pending/Complete)
+- No visual indicator for "no work at all" state
+
+**Fix Applied:**
+```typescript
+// UI Enhancement - 4-state display system
+{status.exploration.chunks.running > 0 ? (
+  <span className="text-yellow-400">⚡ Processing</span>
+) : status.exploration.chunks.pending > 0 ? (
+  <span className="text-blue-400">⏳ Pending</span>
+) : status.exploration.chunks.completed === status.exploration.chunks.total ? (
+  <span className="text-green-400">✅ Complete</span>
+) : (
+  <span className="text-gray-400">⏸️ Idle</span>  // NEW STATE
+)}
+
+// Show pending chunk count
+{status.exploration.chunks.pending > 0 && (
+  <span className="text-gray-400">({status.exploration.chunks.pending} pending)</span>
+)}
+```
+
+**Verification:**
+```bash
+curl -s http://localhost:3001/api/cluster/status | jq '.exploration'
+# After Stop button:
+{
+  "totalCombinations": 4096,
+  "testedCombinations": 0,
+  "progress": 0,
+  "chunks": {
+    "total": 3,
+    "completed": 0,
+    "running": 0,    # ✅ Was 3 before fix
+    "pending": 3     # ✅ Correctly reset
+  }
+}
+```
+
+---
+
+## Technical Implementation
+
+### Database Operations Refactor
+
+**Problem:** Original code used sqlite3 CLI commands
+```typescript
+// ❌ DOESN'T WORK IN DOCKER
+const resetCmd = `sqlite3 ${dbPath} "UPDATE chunks SET status='pending'..."`
+await execAsync(resetCmd)
+// Error: /bin/sh: sqlite3: not found
+```
+
+**Solution:** Use Node.js sqlite library
+```typescript
+// ✅ WORKS IN DOCKER
+const db = await open({
+  filename: dbPath,
+  driver: sqlite3.Database
+})
+await db.run(`UPDATE chunks SET status=?, assigned_worker=NULL WHERE status=?`, 
+  ['pending', 'running'])
+const result = await db.get(`SELECT COUNT(*) as count FROM chunks WHERE status=?`, 
+  ['pending'])
+await db.close()
+```
+
+**Why This Matters:**
+- Docker container uses node:20-alpine (minimal Linux)
+- Alpine doesn't include sqlite3 CLI by default
+- Node.js sqlite3 library already installed (used in status API)
+- Cleaner code, better error handling, no shell dependencies
+
+---
+
+### File Permissions Fix
+
+**Problem:** Database readonly in container
+```
+SQLITE_READONLY: attempt to write a readonly database
+```
+
+**Root Cause:**
+- Database file owned by root (UID 0)
+- Container runs as nextjs user (UID 1001)
+- SQLite needs write access + directory write for lock files
+
+**Solution:**
+```bash
+# Fix database file ownership
+chown 1001:1001 /home/icke/traderv4/cluster/exploration.db
+chmod 664 /home/icke/traderv4/cluster/exploration.db
+
+# Fix directory permissions (for lock files)
+chown 1001:1001 /home/icke/traderv4/cluster
+chmod 775 /home/icke/traderv4/cluster
+
+# Verification:
+ls -la /home/icke/traderv4/cluster/
+drwxrwxr-x 4 1001 1001   30 Dec  1 10:02 .
+-rw-rw-r-- 1 1001 1001 40960 Dec  1 10:02 exploration.db
+```
+
+---
+
+## Deployment Process
+
+### Build & Deploy Steps
+
+1. **Code Changes:**
+   - Updated control/route.ts with database-first logic
+   - Enhanced page.tsx with 4-state display
+   - Replaced sqlite3 CLI with Node.js API
+
+2. **Docker Build:**
+   ```bash
+   docker compose build trading-bot
+   # Build time: ~73 seconds
+   # Image: sha256:7b830abb...
+   ```
+
+3. **Container Restart:**
+   ```bash
+   docker compose up -d --force-recreate trading-bot
+   # Container: trading-bot-v4 started successfully
+   ```
+
+4. **Permission Fix:**
+   ```bash
+   chown 1001:1001 /home/icke/traderv4/cluster/exploration.db
+   chmod 664 /home/icke/traderv4/cluster/exploration.db
+   chown 1001:1001 /home/icke/traderv4/cluster
+   chmod 775 /home/icke/traderv4/cluster
+   ```
+
+5. **Testing:**
+   ```bash
+   # Test Stop button
+   curl -X POST http://localhost:3001/api/cluster/control \
+     -H "Content-Type: application/json" \
+     -d '{"action":"stop"}' | jq .
+   
+   # Result: {"success": true, "message": "Cluster stopped..."}
+   ```
+
+6. **Verification:**
+   ```bash
+   # Check database state
+   sqlite3 exploration.db "SELECT status, COUNT(*) FROM chunks GROUP BY status;"
+   # Result: pending|3 ✅
+   
+   # Check status API
+   curl -s http://localhost:3001/api/cluster/status | jq .exploration
+   # Result: running=0, pending=3, progress=0% ✅
+   ```
+
+---
+
+## Container Logs
+
+**Stop Button Operation (Successful):**
+```
+🛑 Stopping cluster...
+🔧 Resetting database chunks to pending...
+✅ Database cleanup complete - 3 chunks reset to pending (total pending: 3)
+📝 No processes to kill (already stopped)
+```
+
+**Key Log Messages:**
+- `🔧 Resetting database chunks to pending...` - Database operation started
+- `✅ Database cleanup complete - 3 chunks reset` - Success confirmation
+- Shows count of chunks reset and total pending
+- Gracefully handles "no processes to kill" (already crashed scenario)
+
+---
+
+## Testing Results
+
+### Test Case: Stale Database from Coordinator Crash
+
+**Initial State:**
+```sql
+SELECT status, COUNT(*) FROM chunks GROUP BY status;
+-- Result: running|3
+```
+
+**Stop Button Action:**
+```bash
+curl -X POST http://localhost:3001/api/cluster/control \
+  -H "Content-Type: application/json" \
+  -d '{"action":"stop"}' | jq .
+```
+
+**Response:**
+```json
+{
+  "success": true,
+  "message": "Cluster stopped and database reset to pending",
+  "isRunning": false,
+  "note": "All processes stopped, chunks reset"
+}
+```
+
+**Final State:**
+```sql
+SELECT status, COUNT(*) FROM chunks GROUP BY status;
+-- Result: pending|3 ✅
+```
+
+**Status API After Stop:**
+```json
+{
+  "totalCombinations": 4096,
+  "testedCombinations": 0,
+  "progress": 0,
+  "chunks": {
+    "total": 3,
+    "completed": 0,
+    "running": 0,    // Was 3 before
+    "pending": 3     // Correctly reset
+  }
+}
+```
+
+---
+
+## Architecture Decision: Database-First
+
+### Why Database Reset Comes First
+
+**Old Approach (WRONG):**
+```
+Stop Button → pkill processes → wait → reset database
+Problem: If processes already crashed, database never resets
+```
+
+**New Approach (CORRECT):**
+```
+Stop Button → reset database → pkill processes → verify
+Benefit: Database always clean regardless of process state
+```
+
+**Rationale:**
+1. **Idempotency:** Database reset safe to run multiple times
+2. **Crash Recovery:** Works even when coordinator already dead
+3. **User Intent:** "Stop" means "clean up everything" not just "kill processes"
+4. **Restart Readiness:** Fresh database state enables immediate restart
+5. **Error Isolation:** Process kill failure doesn't block database cleanup
+
+**Real-World Scenario:**
+- Coordinator crashes at 2 AM (out of memory, network issue, etc.)
+- Database left with 3 chunks in "running" state
+- User wakes up at 9 AM, sees stale "ACTIVE" status
+- Clicks Stop button
+- OLD: Would fail because processes already gone
+- NEW: Succeeds because database reset happens first ✅
+
+---
+
+## Files Changed
+
+### app/api/cluster/control/route.ts (Major Refactor)
+
+**Before:**
+```typescript
+// Start action - shell command (doesn't work in Docker)
+const resetCmd = `sqlite3 ${dbPath} "UPDATE chunks..."`
+await execAsync(resetCmd)
+
+// Stop action - pkill first, database second
+const stopCmd = 'pkill -9 -f distributed_coordinator'
+await execAsync(stopCmd)
+// ... then reset database
+```
+
+**After:**
+```typescript
+// Imports added:
+import sqlite3 from 'sqlite3'
+import { open } from 'sqlite'
+
+// Start action - Node.js API
+const db = await open({ filename: dbPath, driver: sqlite3.Database })
+await db.run(`UPDATE chunks SET status='pending', assigned_worker=NULL, started_at=NULL WHERE status='running'`)
+await db.close()
+
+// Stop action - DATABASE FIRST
+// 1. Reset database state
+const db = await open({ filename: dbPath, driver: sqlite3.Database })
+const result = await db.run(`UPDATE chunks SET status='pending'...`)
+const pendingCount = await db.get(`SELECT COUNT(*) as count FROM chunks WHERE status='pending'`)
+await db.close()
+
+// 2. THEN kill processes
+const stopCmd = 'pkill -9 -f distributed_coordinator; pkill -9 -f distributed_worker'
+try {
+  await execAsync(stopCmd)
+} catch (err) {
+  console.log('📝 No processes to kill (already stopped)')
+}
+```
+
+**Changes:**
+- Added sqlite3/sqlite imports (lines 5-6)
+- Replaced 3 sqlite3 CLI calls with Node.js API
+- Reordered stop logic (database first, pkill second)
+- Enhanced error handling and logging
+- Added count verification for reset chunks
+
+---
+
+### app/cluster/page.tsx (UI Enhancement)
+
+**Before:**
+```typescript
+// Only 3 states
+{status.exploration.chunks.running > 0 ? (
+  <span>⚡ Processing</span>
+) : status.exploration.chunks.pending > 0 ? (
+  <span>⏳ Pending</span>
+) : (
+  <span>✅ Complete</span>
+)}
+```
+
+**After:**
+```typescript
+// 4 states + pending count display
+{status.exploration.chunks.running > 0 ? (
+  <span className="text-yellow-400">⚡ Processing</span>
+) : status.exploration.chunks.pending > 0 ? (
+  <span className="text-blue-400">⏳ Pending</span>
+) : status.exploration.chunks.completed === status.exploration.chunks.total && 
+   status.exploration.chunks.total > 0 ? (
+  <span className="text-green-400">✅ Complete</span>
+) : (
+  <span className="text-gray-400">⏸️ Idle</span>  // NEW
+)}
+
+// Show pending count when present
+{status.exploration.chunks.pending > 0 && status.exploration.chunks.running === 0 && (
+  <span className="text-gray-400 ml-2">({status.exploration.chunks.pending} pending)</span>
+)}
+```
+
+**Changes:**
+- Added 4th state: "⏸️ Idle" (no work queued)
+- Shows pending chunk count when work queued but not running
+- Better color coding (yellow/blue/green/gray)
+- More precise state logic (checks total > 0 for Complete)
+
+---
+
+## Lessons Learned
+
+### 1. Docker Environment Constraints
+
+**Discovery:** Shell commands that work on host may not exist in Docker container
+
+**Example:**
+- Host: sqlite3 CLI installed system-wide
+- Container: node:20-alpine minimal image (no sqlite3)
+- Solution: Use native libraries already in node_modules
+
+**Takeaway:** Always test in target environment (container), not just on host
+
+---
+
+### 2. Database-First Architecture
+
+**Principle:** Critical state cleanup should happen BEFORE process management
+
+**Example:**
+- OLD: Kill processes → reset database (fails if processes already dead)
+- NEW: Reset database → kill processes (always works)
+
+**Takeaway:** State cleanup operations should be idempotent and order matters
+
+---
+
+### 3. Container User Permissions
+
+**Discovery:** Container runs as UID 1001 (nextjs), not root
+
+**Impact:**
+- Files created by root (UID 0) are readonly to container
+- SQLite needs write access to both file AND directory (for lock files)
+- Permission 644 not enough, need 664 (group write)
+
+**Solution:**
+```bash
+chown 1001:1001 cluster/exploration.db  # Match container user
+chmod 664 cluster/exploration.db        # Group write
+chown 1001:1001 cluster/                # Directory ownership
+chmod 775 cluster/                      # Directory write for locks
+```
+
+**Takeaway:** Always match host file permissions to container user UID
+
+---
+
+### 4. Comprehensive Logging
+
+**Before:** Simple success/failure messages
+
+**After:** Detailed operation flow with counts
+```typescript
+console.log('🔧 Resetting database chunks to pending...')
+console.log(`✅ Database cleanup complete - ${result.changes} chunks reset to pending (total pending: ${pendingCount?.count})`)
+console.log('📝 No processes to kill (already stopped)')
+```
+
+**Benefits:**
+- User sees exactly what happened
+- Debugging issues easier (know which step failed)
+- Confirms operation success with verification counts
+- Distinguishes between "no processes found" vs "kill failed"
+
+**Takeaway:** Verbose logging in infrastructure operations pays off during troubleshooting
+
+---
+
+## Future Enhancements
+
+### 1. Automatic Permission Handling
+
+**Current:** Manual chown/chmod required for database
+
+**Proposed:** Docker entrypoint script that fixes permissions on startup
+```bash
+#!/bin/sh
+# Fix cluster directory permissions
+chown -R nextjs:nodejs /app/cluster
+chmod -R u+rw,g+rw /app/cluster
+exec "$@"
+```
+
+---
+
+### 2. Database Lock File Cleanup
+
+**Current:** SQLite may leave lock files on crash
+
+**Proposed:** Check for stale lock files on Stop
+```typescript
+// In stop action:
+const lockFiles = fs.readdirSync(clusterDir).filter(f => f.includes('.db-'))
+if (lockFiles.length > 0) {
+  console.log(`🗑️ Removing ${lockFiles.length} stale lock files`)
+  lockFiles.forEach(f => fs.unlinkSync(path.join(clusterDir, f)))
+}
+```
+
+---
+
+### 3. Status API Health Checks
+
+**Current:** Status API trusts database without verification
+
+**Proposed:** Cross-check process existence
+```typescript
+// In status API:
+if (runningChunks > 0) {
+  const psOutput = await execAsync('ps aux | grep -c "[d]istributed_coordinator"')
+  const processCount = parseInt(psOutput.stdout)
+  if (processCount === 0) {
+    console.warn('⚠️ Database shows running chunks but no coordinator process!')
+    // Auto-fix: Reset database to pending
+  }
+}
+```
+
+---

+   - Better visual differentiation (colors, emojis)
+   - Accurate state after Stop button operation
+
+### Why It Matters
+
+**User Impact:**
+- Can now confidently restart cluster after crashes
+- Clear visual feedback of cluster state
+- No confusion from stale "ACTIVE" displays
+- Reliable cleanup operation
