 lead record look like in the DB?
 
+### [DevOps] Deployment Optimization (identified 2026-03-09)
+- **Consolidate Service Architecture:** Simplify `ae_env_node_app/docker-compose.yml` by removing the manual Red/Green/Blue/etc. container definitions. Transition to a single service definition that can be scaled using Docker's native `--scale` flag if needed.
+- **Unified Port Mapping:** Standardize on a single exposed port (e.g., 3000 or 3001) for the reverse proxy to point to, rather than managing 4+ separate ports for staging subdomains.
+- **Auto-Healing & Healthchecks:** Implement a `/health` endpoint in the SvelteKit app (`src/routes/health/+server.ts`) and re-enable Docker/Nginx health-based routing to ensure zero-downtime deploys and auto-recovery.
+- **Build Optimization:** Explore using a private container registry to separate the build phase from the deployment phase (Build once, deploy anywhere).
