Subject: [PATCH 1/7] feat: Configure Terraform for production deployment with
 enhanced settings

- Add GCS remote state backend configuration for state management
- Create terraform.tfvars.example template (terraform.tfvars excluded via .gitignore)
- Add explicit IAM roles for Build SA (cloudbuild.builds.editor, run.admin)
- Update Cloud Run to 2 vCPU, 4Gi memory, 30min timeout, concurrency=4 for Veo video generation
- Add GCS bucket lifecycle policy (90-day deletion) to prevent unbounded storage costs
- Add comprehensive resource labels (app, environment, team, owner, cost_center) for cost tracking
- Add reserved IP address support for load balancer
- Ingress already configured for INGRESS_TRAFFIC_INTERNAL_LOAD_BALANCER when use_lb=true
- GCS uniform bucket access already enabled
- Firestore composite indexes already configured
- App SA already uses least-privilege roles (storage.objectCreator not objectAdmin)

+## 11. Recommended Next Steps
+
+### Phase 2: Runtime Validation
+
+1. **Verify Database Connectivity**
+   ```bash
+   # Test Firestore client initialization
+   python -c "from config.firebase_config import FirebaseClient; \
+              client = FirebaseClient('create-studio-asset-metadata'); \
+              print('Connection successful')"
+   ```
+
+2. **Verify GCS Bucket Access**
+   ```bash
+   # List bucket contents
+   gcloud storage ls gs://creative-studio-genai-creative-studio-assets/
+
+   # Test upload
+   echo "test" > test.txt
+   gcloud storage cp test.txt gs://creative-studio-genai-creative-studio-assets/validation/
+   ```
+
+3. **Check Cloud Run Logs**
+   ```bash
+   # View recent logs
+   gcloud run services logs read creative-studio \
+     --project=genai-creative-studio \
+     --region=us-central1 \
+     --limit=50
+   ```
+
+4. **Test Media Generation Flow**
+   - Generate a test image via Imagen
+   - Verify GCS upload
+   - Verify Firestore metadata creation
+   - Check media proxy endpoint
+
+5. **Validate Firestore Indexes**
+   ```bash
+   # Check index build status
+   gcloud firestore indexes list \
+     --database=create-studio-asset-metadata \
+     --project=genai-creative-studio
+   ```
+
+### Phase 3: Performance & Monitoring
+
+1. Set up Cloud Monitoring dashboards for:
+   - Firestore read/write operations
+   - GCS upload/download metrics
+   - Cloud Run request latency
+   - Error rates
+
+2. Enable alerting for:
+   - Database quota exceeded
+   - Storage bucket nearing capacity
+   - Cloud Run cold start times
+   - Failed media generation attempts

+
+---
+
+## 13. Support & Troubleshooting
+
+### Common Issues
+
+1. **"Database not found" error**
+   - Verify `GENMEDIA_FIREBASE_DB` environment variable
+   - Check service account has `datastore.user` role
+
+2. **"Permission denied" on GCS operations**
+   - Verify service account bucket IAM bindings
+   - Check bucket name matches environment variable
+
+3. **Firestore query timeout**
+   - Verify indexes are built (not in CREATING state)
+   - Check network connectivity from Cloud Run
+
+### Debug Commands
+
+```bash
+# Check Firestore database details
+gcloud firestore databases describe create-studio-asset-metadata \
+  --project=genai-creative-studio
+
+# Check GCS bucket configuration
+gcloud storage buckets describe \
+  gs://creative-studio-genai-creative-studio-assets
+
+# Check Cloud Run service
+gcloud run services describe creative-studio \
+  --region=us-central1 \
+  --project=genai-creative-studio
+
+# Check service account permissions

+---
+
+## 10. Recommended Monitoring & Alerting
+
+### 10.1 Cloud Monitoring Dashboards
+
+**Suggested Metrics to Track**:
+
+**Firestore Metrics**:
+```
+- firestore.googleapis.com/document/read_count
+- firestore.googleapis.com/document/write_count
+- firestore.googleapis.com/document/delete_count
+- firestore.googleapis.com/api/request_count (by status)
+- firestore.googleapis.com/api/request_latencies
+```
+
+**Cloud Storage Metrics**:
+```
+- storage.googleapis.com/storage/object_count
+- storage.googleapis.com/storage/total_bytes
+- storage.googleapis.com/network/sent_bytes_count
+- storage.googleapis.com/network/received_bytes_count
+```
+
+**Cloud Run Metrics**:
+```
+- run.googleapis.com/request_count
+- run.googleapis.com/request_latencies
+- run.googleapis.com/container/instance_count
+- run.googleapis.com/container/cpu/utilizations
+- run.googleapis.com/container/memory/utilizations
+```
+
+---
+
+### 10.2 Recommended Alerts
+
+**Critical Alerts**:
+1. **Firestore errors > 1% of requests** (5-minute window)
+2. **Cloud Run 5xx errors > 5 in 5 minutes**
+3. **GCS bucket approaching quota** (>80% of free tier)
+4. **Cloud Run cold starts > 60 seconds** (performance degradation)
+
+**Warning Alerts**:
+1. **Firestore read operations > 10,000/day** (approaching free tier limit)
+2. **GCS egress > 10GB/day** (cost optimization)
+3. **Cloud Run instance count > 4** (approaching max scale)
+
+**Alerting Channels**:
+- Email notifications
+- Cloud Logging integration
+- Optional: Slack/PagerDuty webhooks
+
+---
+
+## 11. Known Observations & Notes
+
+### 11.1 Environment Variable: APP_ENV
+
+**Observed Value**: `local`
+
+**Current Configuration**:
+```yaml
+APP_ENV: local
+```
+
+**Note**: This is set to "local" but the service is running in production. Consider reviewing if this should be changed to `prod` or `production` for clarity.
+
+**Impact**: Low priority - primarily affects logging verbosity and debug behaviors
+
+**Recommendation**: Review and update if needed:
+```hcl
+# In main.tf, add to local.creative_studio_env_vars:
+APP_ENV = "prod"
+```
+
+---
+
+### 11.2 Worker Restart Messages
+
+**Observed**:
+```
+[ERROR] Worker (pid:2) was sent SIGTERM!
+```
+
+**Analysis**: This is **normal behavior** during Cloud Run revision updates. Not an application error.
+
+**Frequency**: Only occurs during deployments
+
+**Action Required**: None - informational only
+
+---
+

+
+---
+
+## 13. Next Steps (Optional)
+
+### Phase 3: Load Testing (Optional)
+
+If you want to perform load testing:
+
+1. **Generate test media items**:
+   ```bash
+   # Use the application UI to generate 10-20 test assets
+   # Verify they appear in Firestore and GCS
+   ```
+
+2. **Query performance testing**:
+   ```python
+   # Test paginated queries with different page sizes
+   # Verify index usage with explain plans
+   ```
+
+3. **Media proxy load test**:
+   ```bash
+   # Use Apache Bench or similar to test concurrent media requests
+   ab -n 1000 -c 10 https://creative-studio-dktxnkixva-uc.a.run.app/media/...
+   ```
+
+### Phase 4: Cost Monitoring (Recommended)
+
+1. Set up billing alerts for:
+   - Firestore operations exceeding free tier
+   - GCS storage approaching quota
+   - Cloud Run invocations
+
+2. Review monthly costs in Cloud Billing console
+
+3. Optimize lifecycle policies if needed
+

+
+## Appendix B: Troubleshooting Guide
+
+### Issue: "Permission denied" errors in logs
+
+**Possible Causes**:
+- Service account lacks required IAM roles
+- IAM condition too restrictive
+- Bucket IAM bindings not applied
+
+**Resolution**:
+```bash
+# Check service account permissions
+gcloud projects get-iam-policy $PROJECT_ID \
+  --flatten="bindings[].members" \
+  --filter="bindings.members:serviceAccount:service-creative-studio@"
+
+# Re-apply Terraform if needed
+terraform apply
+```
+
+---
+
+### Issue: Firestore queries timeout
+
+**Possible Causes**:
+- Indexes not built (STATE: CREATING)
+- Network connectivity issues
+- Database in different region than Cloud Run
+
+**Resolution**:
+```bash
+# Verify indexes are READY
+gcloud firestore indexes composite list --database=$DATABASE
+
+# Check Cloud Run logs for specific error messages
+gcloud run services logs read $SERVICE --limit=100 | grep -i timeout
+```
+
+---
+
+### Issue: Media files return 404
+
+**Possible Causes**:
+- GCS object doesn't exist
+- Service account lacks storage.objectViewer role
+- Bucket name mismatch in environment variables
+
+**Resolution**:
+```bash
+# Verify object exists
+gcloud storage ls gs://$BUCKET/path/to/file
+
+# Check bucket permissions
+gcloud storage buckets get-iam-policy gs://$BUCKET
+
+# Verify environment variables
+gcloud run services describe $SERVICE --format="yaml(spec.template.spec.containers[0].env)"
+```
