+# Entity Submission Flow - CRITICAL SECURITY PATTERN
+
+## The Sacred Flow
+
+Every entity creation or edit MUST follow this exact flow:
+
+```
+1. User fills form
+   ↓
+2. Submission created → moderation queue
+   ↓
+3. Moderator reviews & approves
+   ↓
+4. Edge function writes to database (via service role)
+   ↓
+5. Versioning system captures change
+   ↓
+6. Public can view live entity
+```
+
+## ❌ NEVER DO THIS
+
+```ts
+// Direct database write - BYPASSES EVERYTHING!
+await supabase.from('parks').insert(parkData);
+await supabase.from('rides').update({ id: rideId }, rideData);
+
+// Even if you're a moderator/admin:
+if (isAdmin) {
+  await supabase.from('parks').insert(parkData); // STILL WRONG!
+}
+```
+
+**Why this is blocked:**
+- RLS policies explicitly deny INSERT/UPDATE to authenticated users
+- Only the service role (edge functions) can write
+- Edge functions are ONLY triggered by moderation approval
+
+## ✅ ALWAYS DO THIS
+
+```ts
+// Import the submission helpers
+import { 
+  submitParkCreation, 
+  submitParkUpdate,
+  submitRideCreation,
+  submitRideUpdate 
+} from '@/lib/entitySubmissionHelpers';
+
+// For new entities:
+const result = await submitParkCreation(parkData, user.id);
+
+// For editing existing entities:
+const result = await submitParkUpdate(parkId, parkData, user.id);
+```
+
+## For React Components
+
+Use the enforced wrappers:
+
+```tsx
+import { enforceParkSubmissionFlow } from '@/lib/entityFormValidation';
+
+// In your component:
+const handleSubmit = enforceParkSubmissionFlow(isEditing, park?.id);
+
+<ParkForm
+  isEditing={isEditing}
+  initialData={park}
+  onSubmit={async (data) => {
+    await handleSubmit(data, user!.id);
+    toast({ title: "Submitted for review" });
+  }}
+/>
+```
+
+## Why This Matters
+
+### Security
+- Prevents spam and vandalism
+- Rate-limits submissions via queue system
+- Blocks malicious automated bots
+
+### Quality
+- Human review catches errors, duplicates, inappropriate content
+- Maintains high data quality standards
+
+### Accountability
+- Full version history with user attribution
+- Every change is tracked and auditable
+- Can rollback any change
+
+### Compliance
+- Complete audit trail for legal/regulatory requirements
+- User attribution for all content
+
+## For Moderators/Admins
+
+**Even moderators must follow the flow:**
+
+1. Create/edit submission through normal UI
+2. It goes to moderation queue
+3. Review your own submission
+4. Approve it
+
+**Why?** 
+- Ensures versioning captures the change
+- Creates audit trail
+- Prevents accidental mistakes
+
+**Exception:**
+Only emergency database fixes via SQL editor should bypass this. These should be:
+- Extremely rare
+- Documented in admin_audit_log
+- Followed by manual version creation if needed
+
+## Database Protection
+
+### RLS Policies
+The following tables have explicit denial policies:
+- `parks` - INSERT/UPDATE blocked for authenticated users
+- `rides` - INSERT/UPDATE blocked for authenticated users
+- `companies` - INSERT/UPDATE blocked for authenticated users
+- `ride_models` - INSERT/UPDATE blocked for authenticated users
+
+### Service Role Access
+Only these edge functions can write (they use service role):
+- `process-selective-approval` - Applies approved submissions
+- Direct SQL migrations (admin only)
+
+### Versioning Triggers
+All entity writes trigger `auto_create_entity_version()`:
+- Captures full entity state
+- Records user who made change
+- Creates diff of what changed
+- Logs to audit trail if user attribution missing
+
+## Error Messages
+
+If you see these errors, you're trying to bypass the flow:
+
+```
+Error: new row violates row-level security policy
+```
+→ You tried to INSERT/UPDATE directly. Use submission helpers.
+
+```
+Error: permission denied for table parks/rides/companies/ride_models
+```
+→ Same issue - use submission helpers.
+
+## Testing the Flow
+
+### Manual Test:
+1. Create a new park through the UI
+2. Check `content_submissions` table - should have new row
+3. Check `submission_items` table - should have park data
+4. Approve via moderation queue
+5. Check `parks` table - entity should appear
+6. Check `entity_versions` table - version should be created
+7. Version should have correct `changed_by` user_id
+
+### Automated Test:
+```ts
+// Test that direct writes are blocked
+try {
+  await supabase.from('parks').insert({ name: 'Test Park' });
+  throw new Error('Expected RLS to block this');
+} catch (error) {
+  // Should get permission denied error
+  expect(error.message).toContain('row-level security');
+}
+
+// Test that submission flow works
+const result = await submitParkCreation(parkData, userId);
+expect(result.submitted).toBe(true);
+```
+
+## Monitoring
+
+### Dashboard Widgets
+Check the admin dashboard for:
+- **Suspicious Versions** - Versions without user attribution
+- **Queue Backlog** - Submissions waiting too long
+- **Flow Violations** - Any attempts to bypass the flow
+
+### Audit Logs
+```sql
+-- Check for versions without user attribution
+SELECT * FROM entity_versions 
+WHERE changed_by IS NULL 
+ORDER BY changed_at DESC;
+
+-- Check for direct writes (should be none except migrations)
+SELECT * FROM admin_audit_log 
+WHERE action = 'version_without_user'
+ORDER BY created_at DESC;
+```
+
+## Common Pitfalls
+
+### ❌ "I'll just fix this one typo directly"
+Even small fixes must go through the flow. Creates version history.
+
+### ❌ "I'm an admin, I can bypass this"
+No. Admins follow the flow. Prevents mistakes and maintains audit trail.
+
+### ❌ "This is taking too long, I'll do it in SQL editor"
+Only for emergencies. Document it. Create manual version if needed.
+
+### ❌ "I'll bulk import via CSV"
+Bulk imports should:
+1. Create submissions programmatically
+2. Auto-approve them if from trusted source
+3. Still trigger versioning
+
+## Questions?
+
+**Q: What if I need to bulk import 1000 parks?**
+A: Create submissions programmatically, set `status='approved'`, let edge function process them.
+
+**Q: What if there's an emergency typo on homepage?**
+A: Make the fix via submission → have another mod approve immediately. Takes <1 minute.
+
+**Q: What if the moderation queue is broken?**
+A: Fix the queue. Don't bypass the flow. That creates worse problems.
+
+**Q: Can I use the service role key directly?**
+A: Only in edge functions. Never in client-side code. Never for routine edits.
