# Phase 2: Automated Cleanup Jobs - COMPLETE ✅

## Overview
Implemented comprehensive automated cleanup system to prevent database bloat and maintain Sacred Pipeline health. All cleanup tasks run via a master function with detailed logging and error handling.

---

## 🎯 Implemented Cleanup Functions

### 1. **cleanup_expired_idempotency_keys()**
**Purpose**: Remove idempotency keys that expired over 1 hour ago
**Retention**: Keys expire after 24 hours, deleted after 25 hours
**Returns**: Count of deleted keys

**Example**:
```sql
SELECT cleanup_expired_idempotency_keys();
-- Returns: 42 (keys deleted)
```

---

### 2. **cleanup_stale_temp_refs(p_age_days INTEGER DEFAULT 30)**
**Purpose**: Remove temporary submission references older than specified days
**Retention**: 30 days default (configurable)
**Returns**: Deleted count and oldest deletion date

**Example**:
```sql
SELECT * FROM cleanup_stale_temp_refs(30);
-- Returns: (deleted_count: 15, oldest_deleted_date: '2024-10-08')
```

---

### 3. **cleanup_abandoned_locks()** ⭐ NEW
**Purpose**: Release locks from deleted users, banned users, and expired locks
**Returns**: Released count and breakdown by reason

**Handles**:
- Locks from deleted users (no longer in auth.users)
- Locks from banned users (profiles.banned = true)
- Expired locks (locked_until < NOW())

**Example**:
```sql
SELECT * FROM cleanup_abandoned_locks();
-- Returns: 
-- {
--   released_count: 8,
--   lock_details: {
--     deleted_user_locks: 2,
--     banned_user_locks: 3,
--     expired_locks: 3
--   }
-- }
```

---

### 4. **cleanup_old_submissions(p_retention_days INTEGER DEFAULT 90)** ⭐ NEW
**Purpose**: Delete old approved/rejected submissions to reduce database size
**Retention**: 90 days default (configurable)
**Preserves**: Pending submissions, test data
**Returns**: Deleted count, status breakdown, oldest deletion date

**Example**:
```sql
SELECT * FROM cleanup_old_submissions(90);
-- Returns: 
-- {
--   deleted_count: 156,
--   deleted_by_status: { "approved": 120, "rejected": 36 },
--   oldest_deleted_date: '2024-08-10'
-- }
```

---

## 🎛️ Master Cleanup Function

### **run_all_cleanup_jobs()** ⭐ NEW
**Purpose**: Execute all 4 cleanup tasks in one call with comprehensive error handling
**Features**:
- Individual task exception handling (one failure doesn't stop others)
- Detailed execution results with success/error per task
- Performance timing and logging

**Example**:
```sql
SELECT * FROM run_all_cleanup_jobs();
```

**Returns**:
```json
{
  "idempotency_keys": {
    "deleted": 42,
    "success": true
  },
  "temp_refs": {
    "deleted": 15,
    "oldest_date": "2024-10-08T14:32:00Z",
    "success": true
  },
  "locks": {
    "released": 8,
    "details": {
      "deleted_user_locks": 2,
      "banned_user_locks": 3,
      "expired_locks": 3
    },
    "success": true
  },
  "old_submissions": {
    "deleted": 156,
    "by_status": {
      "approved": 120,
      "rejected": 36
    },
    "oldest_date": "2024-08-10T09:15:00Z",
    "success": true
  },
  "execution": {
    "started_at": "2024-11-08T03:00:00Z",
    "completed_at": "2024-11-08T03:00:02.345Z",
    "duration_ms": 2345
  }
}
```

## 🚀 Edge Function

### **run-cleanup-jobs**
**URL**: `https://api.thrillwiki.com/functions/v1/run-cleanup-jobs`
**Auth**: No JWT required (called by pg_cron)
**Method**: POST

**Purpose**: Wrapper edge function for pg_cron scheduling
**Features**:
- Calls `run_all_cleanup_jobs()` via service role
- Structured JSON logging
- Individual task failure warnings
- CORS enabled for manual testing

**Manual Test**:
```bash
curl -X POST https://api.thrillwiki.com/functions/v1/run-cleanup-jobs \
  -H "Content-Type: application/json"
```

---

## ⏰ Scheduling with pg_cron

### ✅ Prerequisites (ALREADY MET)
1. ✅ `pg_cron` extension enabled (v1.6.4)
2. ✅ `pg_net` extension enabled (for HTTP requests)
3. ✅ Edge function deployed: `run-cleanup-jobs`

### 📋 Schedule Daily Cleanup (3 AM UTC)

**IMPORTANT**: Run this SQL directly in your [Supabase SQL Editor](https://supabase.com/dashboard/project/ydvtmnrszybqnbcqbdcy/sql/new):

```sql
-- Schedule cleanup jobs to run daily at 3 AM UTC
SELECT cron.schedule(
  'daily-pipeline-cleanup',           -- Job name
  '0 3 * * *',                        -- Cron expression (3 AM daily)
  $$
  SELECT net.http_post(
    url := 'https://api.thrillwiki.com/functions/v1/run-cleanup-jobs',
    headers := '{"Content-Type": "application/json", "Authorization": "Bearer eyJhbGciOiJIUzI1NiIsInR5cCI6IkpXVCJ9.eyJpc3MiOiJzdXBhYmFzZSIsInJlZiI6InlkdnRtbnJzenlicW5iY3FiZGN5Iiwicm9sZSI6ImFub24iLCJpYXQiOjE3NTgzMjYzNTYsImV4cCI6MjA3MzkwMjM1Nn0.DM3oyapd_omP5ZzIlrT0H9qBsiQBxBRgw2tYuqgXKX4"}'::jsonb,
    body := '{"scheduled": true}'::jsonb
  ) as request_id;
  $$
);
```

**Alternative Schedules**:
```sql
-- Every 6 hours: '0 */6 * * *'
-- Every hour:    '0 * * * *'
-- Every Sunday:  '0 3 * * 0'
-- Twice daily:   '0 3,15 * * *' (3 AM and 3 PM)
```

### Verify Scheduled Job

```sql
-- Check active cron jobs
SELECT * FROM cron.job WHERE jobname = 'daily-pipeline-cleanup';

-- View cron job history
SELECT * FROM cron.job_run_details 
WHERE jobid = (SELECT jobid FROM cron.job WHERE jobname = 'daily-pipeline-cleanup')
ORDER BY start_time DESC
LIMIT 10;
```

### Unschedule (if needed)

```sql
SELECT cron.unschedule('daily-pipeline-cleanup');
```

---

## 📊 Monitoring & Alerts

### Check Last Cleanup Execution
```sql
-- View most recent cleanup results (check edge function logs)
-- Or query cron.job_run_details for execution status
SELECT 
  start_time,
  end_time,
  status,
  return_message
FROM cron.job_run_details 
WHERE jobid = (SELECT jobid FROM cron.job WHERE jobname = 'daily-pipeline-cleanup')
ORDER BY start_time DESC
LIMIT 1;
```

### Database Size Monitoring
```sql
-- Check table sizes to verify cleanup is working
SELECT 
  schemaname,
  tablename,
  pg_size_pretty(pg_total_relation_size(schemaname||'.'||tablename)) AS size
FROM pg_tables
WHERE schemaname = 'public'
  AND tablename IN (
    'submission_idempotency_keys',
    'submission_item_temp_refs',
    'content_submissions'
  )
ORDER BY pg_total_relation_size(schemaname||'.'||tablename) DESC;
```

---

## 🧪 Manual Testing

### Test Individual Functions
```sql
-- Test each cleanup function independently
SELECT cleanup_expired_idempotency_keys();
SELECT * FROM cleanup_stale_temp_refs(30);
SELECT * FROM cleanup_abandoned_locks();
SELECT * FROM cleanup_old_submissions(90);
```

### Test Master Function
```sql
-- Run all cleanup jobs manually
SELECT * FROM run_all_cleanup_jobs();
```

### Test Edge Function
```bash
# Manual HTTP test
curl -X POST https://api.thrillwiki.com/functions/v1/run-cleanup-jobs \
  -H "Content-Type: application/json" \
  -H "Authorization: Bearer YOUR_ANON_KEY"
```

---

## 📈 Expected Cleanup Rates

Based on typical usage patterns:

| Task | Frequency | Expected Volume |
|------|-----------|-----------------|
| Idempotency Keys | Daily | 50-200 keys/day |
| Temp Refs | Daily | 10-50 refs/day |
| Abandoned Locks | Daily | 0-10 locks/day |
| Old Submissions | Daily | 50-200 submissions/day (after 90 days) |

---

## 🔒 Security

- All cleanup functions use `SECURITY DEFINER` with `SET search_path = public`
- RLS policies verified for all affected tables
- Edge function uses service role key (not exposed to client)
- No user data exposure in logs (only counts and IDs)

---

## 🚨 Troubleshooting

### Cleanup Job Fails Silently
**Check**:
1. pg_cron extension enabled: `SELECT * FROM pg_available_extensions WHERE name = 'pg_cron' AND installed_version IS NOT NULL;`
2. pg_net extension enabled: `SELECT * FROM pg_available_extensions WHERE name = 'pg_net' AND installed_version IS NOT NULL;`
3. Edge function deployed: Check Supabase Functions dashboard
4. Cron job scheduled: `SELECT * FROM cron.job WHERE jobname = 'daily-pipeline-cleanup';`

### Individual Task Failures
**Solution**: Check edge function logs for specific error messages
- Navigate to: https://supabase.com/dashboard/project/ydvtmnrszybqnbcqbdcy/functions/run-cleanup-jobs/logs

### High Database Size After Cleanup
**Check**:
- Vacuum table: `VACUUM FULL content_submissions;` (requires downtime)
- Check retention periods are appropriate
- Verify CASCADE DELETE constraints working

---

## ✅ Success Metrics

After implementing Phase 2, monitor these metrics:

1. **Database Size Reduction**: 10-30% decrease in `content_submissions` table size after 90 days
2. **Lock Availability**: <1% of locks abandoned/stuck
3. **Idempotency Key Volume**: Stable count (not growing unbounded)
4. **Cleanup Success Rate**: >99% of scheduled jobs complete successfully

---

## 🎯 Next Steps

With Phase 2 complete, the Sacred Pipeline now has:
- ✅ Pre-approval validation (Phase 1)
- ✅ Enhanced error logging (Phase 1)
- ✅ CHECK constraints (Phase 1)
- ✅ Automated cleanup jobs (Phase 2)

**Recommended Next Phase**:
- Phase 3: Enhanced Error Handling
  - Transaction status polling endpoint
  - Expanded error sanitizer patterns
  - Rate limiting for submission creation
  - Form state persistence
