Architectural Prevention & Performance Tuning Checklist
- Always register health check endpoints (`/healthz`) so APIML routes around degraded LPARs automatically.
- Use PassTickets to authenticate seamlessly to backend CICS/IMS regions without exposing user passwords.
- Publish OpenAPI 3.0 specifications to the Zowe API Catalog for developer self-service documentation.
