+# Atomic Approval Transactions
+
+## Overview
+
+Phase 1 of the atomic transaction RPC implementation has been completed. This replaces the error-prone manual rollback logic in the `process-selective-approval` edge function with a true PostgreSQL ACID transaction.
+
+## Architecture
+
+### OLD Flow (process-selective-approval)
+```
+Edge Function (2,759 lines) ──┐
+  ├─ Create entity 1         ├─ Manual rollback on error
+  ├─ Create entity 2         ├─ Network failure = orphaned data
+  ├─ Create entity 3         ├─ Edge function crash = partial state
+  └─ Manual rollback if error─┘
+```
+
+### NEW Flow (process-selective-approval-v2)
+```
+Edge Function (~200 lines)
+  │
+  └──> RPC: process_approval_transaction()
+       │
+       └──> PostgreSQL Transaction ───────────┐
+            ├─ Create entity 1              │
+            ├─ Create entity 2              │ ATOMIC
+            ├─ Create entity 3              │ (all-or-nothing)
+            └─ Commit OR Rollback ──────────┘
+               (any error = auto rollback)
+```
+
+## Key Benefits
+
+✅ **True ACID Transactions**: All operations succeed or fail together  
+✅ **Automatic Rollback**: ANY error triggers immediate rollback  
+✅ **Network Resilient**: Edge function crash = automatic rollback  
+✅ **Zero Orphaned Entities**: Impossible by design  
+✅ **Simpler Code**: Edge function reduced from 2,759 to ~200 lines  
+
+## Database Functions Created
+
+### Main Transaction Function
+```sql
+process_approval_transaction(
+  p_submission_id UUID,
+  p_item_ids UUID[],
+  p_moderator_id UUID,
+  p_submitter_id UUID,
+  p_request_id TEXT DEFAULT NULL
+) RETURNS JSONB
+```
+
+### Helper Functions
+- `create_entity_from_submission()` - Creates entities (parks, rides, companies, etc.)
+- `update_entity_from_submission()` - Updates existing entities
+- `delete_entity_from_submission()` - Soft/hard deletes entities
+
+### Monitoring Table
+- `approval_transaction_metrics` - Tracks performance, success rate, and rollbacks
+
+## Feature Flag
+
+The new flow is **disabled by default** to allow gradual rollout and testing.
+
+### Enabling the New Flow
+
+#### For Moderators (via Admin UI)
+1. Navigate to Admin Settings
+2. Find "Approval Transaction Mode" card
+3. Toggle "Use Atomic Transaction RPC" to ON
+4. Page will reload automatically
+
+#### Programmatically
+```typescript
+// Enable
+localStorage.setItem('use_rpc_approval', 'true');
+
+// Disable
+localStorage.setItem('use_rpc_approval', 'false');
+
+// Check status
+const isEnabled = localStorage.getItem('use_rpc_approval') === 'true';
+```
+
+## Testing Checklist
+
+### Basic Functionality ✓
+- [ ] Enable feature flag via admin UI
+- [ ] Approve a simple submission (1-2 items)
+- [ ] Verify entities created correctly
+- [ ] Check console logs for "Using edge function: process-selective-approval-v2"
+- [ ] Verify version history shows correct attribution
+
+### Error Scenarios ✓
+- [ ] Submit invalid data → verify full rollback
+- [ ] Trigger validation error → verify no partial state
+- [ ] Kill edge function mid-execution → verify auto rollback
+- [ ] Check logs for "Transaction failed, rolling back" messages
+
+### Concurrent Operations ✓
+- [ ] Two moderators approve same submission → one succeeds, one gets locked error
+- [ ] Verify only one set of entities created (no duplicates)
+
+### Data Integrity ✓
+- [ ] Run orphaned entity check (see SQL query below)
+- [ ] Verify session variables cleared after transaction
+- [ ] Check `approval_transaction_metrics` for success rate
+
+## Monitoring Queries
+
+### Check for Orphaned Entities
+```sql
+-- Should return 0 rows after migration
+SELECT 
+  'parks' as table_name,
+  COUNT(*) as orphaned_count
+FROM parks p
+WHERE NOT EXISTS (
+  SELECT 1 FROM park_versions pv
+  WHERE pv.park_id = p.id
+)
+AND p.created_at > NOW() - INTERVAL '24 hours'
+
+UNION ALL
+
+SELECT 
+  'rides' as table_name,
+  COUNT(*) as orphaned_count
+FROM rides r
+WHERE NOT EXISTS (
+  SELECT 1 FROM ride_versions rv
+  WHERE rv.ride_id = r.id
+)
+AND r.created_at > NOW() - INTERVAL '24 hours';
+```
+
+### Transaction Success Rate
+```sql
+SELECT 
+  DATE_TRUNC('hour', created_at) as hour,
+  COUNT(*) as total_transactions,
+  COUNT(*) FILTER (WHERE success) as successful,
+  COUNT(*) FILTER (WHERE rollback_triggered) as rollbacks,
+  ROUND(AVG(duration_ms), 2) as avg_duration_ms,
+  ROUND(100.0 * COUNT(*) FILTER (WHERE success) / COUNT(*), 2) as success_rate
+FROM approval_transaction_metrics
+WHERE created_at > NOW() - INTERVAL '24 hours'
+GROUP BY hour
+ORDER BY hour DESC;
+```
+
+### Rollback Rate Alert
+```sql
+-- Alert if rollback_rate > 5%
+SELECT 
+  COUNT(*) FILTER (WHERE rollback_triggered) as rollbacks,
+  COUNT(*) as total_attempts,
+  ROUND(100.0 * COUNT(*) FILTER (WHERE rollback_triggered) / COUNT(*), 2) as rollback_rate
+FROM approval_transaction_metrics
+WHERE created_at > NOW() - INTERVAL '1 hour'
+HAVING COUNT(*) FILTER (WHERE rollback_triggered) > 0;
+```
+
+## Rollback Plan
+
+If issues are detected after enabling the new flow:
+
+### Immediate Rollback (< 5 minutes)
+```javascript
+// Disable feature flag globally (or ask users to toggle off)
+localStorage.setItem('use_rpc_approval', 'false');
+window.location.reload();
+```
+
+### Data Recovery (if needed)
+```sql
+-- Identify submissions processed with v2 during problem window
+SELECT 
+  atm.submission_id,
+  atm.created_at,
+  atm.success,
+  atm.error_message
+FROM approval_transaction_metrics atm
+WHERE atm.created_at BETWEEN '2025-11-06 19:00:00' AND '2025-11-06 20:00:00'
+  AND atm.success = false
+  AND atm.rollback_triggered = true;
+
+-- Check for orphaned entities (if any exist)
+-- Use the orphaned entity query above
+```
+
+## Success Metrics
+
+After full rollout, these metrics should be achieved:
+
+| Metric | Target | Current |
+|--------|--------|---------|
+| Zero orphaned entities | 0 | ✓ TBD |
+| Zero manual rollback logs | 0 | ✓ TBD |
+| Transaction success rate | >99% | ✓ TBD |
+| Avg transaction time | <500ms | ✓ TBD |
+| Rollback rate | <1% | ✓ TBD |
+
+## Deployment Phases
+
+### Phase 1: ✅ COMPLETE
+- [x] Create RPC functions (helper + main transaction)
+- [x] Create new edge function v2
+- [x] Add feature flag support to frontend
+- [x] Create admin UI toggle
+- [x] Add monitoring table + RLS policies
+
+### Phase 2: 🟡 IN PROGRESS
+- [ ] Test with single moderator account
+- [ ] Monitor metrics for 24 hours
+- [ ] Verify zero orphaned entities
+- [ ] Collect feedback from test moderator
+
+### Phase 3: 🔲 PENDING
+- [ ] Enable for 10% of requests (weighted sampling)
+- [ ] Monitor for 24 hours
+- [ ] Check rollback rate < 1%
+
+### Phase 4: 🔲 PENDING
+- [ ] Enable for 50% of requests
+- [ ] Monitor for 48 hours
+- [ ] Compare performance metrics with old flow
+
+### Phase 5: 🔲 PENDING
+- [ ] Enable for 100% of requests
+- [ ] Monitor for 1 week
+- [ ] Mark old edge function as deprecated
+
+### Phase 6: 🔲 PENDING
+- [ ] Remove old edge function
+- [ ] Archive manual rollback code
+- [ ] Update all documentation
+
+## Troubleshooting
+
+### Issue: Feature flag not working
+**Symptom**: Logs still show "process-selective-approval" even with flag enabled  
+**Solution**: Clear localStorage and reload: `localStorage.clear(); window.location.reload()`
+
+### Issue: "RPC function not found" error
+**Symptom**: Edge function fails with "process_approval_transaction not found"  
+**Solution**: Run the migration again or check function exists:
+```sql
+SELECT proname FROM pg_proc WHERE proname = 'process_approval_transaction';
+```
+
+### Issue: High rollback rate (>5%)
+**Symptom**: Many transactions rolling back in metrics  
+**Solution**: 
+1. Check error messages in `approval_transaction_metrics.error_message`
+2. Disable feature flag immediately
+3. Investigate root cause (validation issues, data integrity, etc.)
+
+### Issue: Orphaned entities detected
+**Symptom**: Entities exist without corresponding versions  
+**Solution**: 
+1. Disable feature flag immediately
+2. Run orphaned entity query to identify affected entities
+3. Investigate cause (likely edge function crash during v1 flow)
+4. Consider data cleanup (manual deletion or version creation)
+
+## FAQ
+
+**Q: Can I switch back to the old flow without data loss?**  
+A: Yes. Simply toggle off the feature flag. All data remains intact.
+
+**Q: What happens if the edge function crashes mid-transaction?**  
+A: PostgreSQL automatically rolls back the entire transaction. No orphaned data.
+
+**Q: How do I know which flow approved a submission?**  
+A: Check `approval_transaction_metrics` table. If a row exists, v2 was used.
+
+**Q: Can I use both flows simultaneously?**  
+A: Yes. The feature flag is per-browser, so different moderators can use different flows.
+
+**Q: When will the old flow be removed?**  
+A: After 30 days of stable operation at 100% rollout (Phase 6).

+-- ATOMIC APPROVAL TRANSACTION - Phase 1 Implementation
+-- ============================================================================
+-- This migration creates RPC functions that wrap the entire approval flow
+-- in a single PostgreSQL transaction for true atomic rollback.
+--
+-- Key Benefits:
+-- 1. True ACID transactions - all-or-nothing guarantee
+-- 2. Automatic rollback on ANY error (no manual cleanup needed)
+-- 3. Network-resilient (edge function crash = auto rollback)
+-- 4. Eliminates orphaned entities
+-- 5. Simplifies edge function from 2,759 lines to ~200 lines
+-- ============================================================================
+
+-- Create metrics table for monitoring transaction performance
