> For the complete documentation index, see [llms.txt](https://deploy-preview-472--lucky-concha-f3599f.netlify.app/llms.txt).

*   Primary smoke script: `scripts/test-state-004-containerized.sh`
    
*   Required checks for this state:
    
    *   Containerized ingress/runtime baseline smoke checks pass.
    *   Header title renders `TraderX Sample Trading App (004-containerized-compose-runtime)`.
    *   `About` tab is visible and routes to an About page with:
        *   active state id,
        *   generated timestamp,
        *   source generated-state branch,
        *   prior-state branch list with short feature-summary sentence,
        *   API explorer link.
    *   `Status` tab is visible and routes to a page showing per-service uptime/health status in containerized runtime.
    *   Runtime/start scripts report current generated state id and mismatch guidance before startup.
    *   Optional auto-regenerate mode for mismatch handling is validated in smoke workflow.
