# Research: Containerized Compose Runtime

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

## Objective

Define the transition from state `003` to `004` by moving the runtime to Docker Compose with NGINX ingress.

## Inputs Reviewed

*   `spec.md`
*   `plan.md`
*   `tasks.md`
*   `system/architecture.md`
*   `system/runtime-topology.md`

## Key Decisions

1.  Preserve service behavior and contracts while containerizing deployment.
2.  Use compose orchestration as the canonical local runtime for this state.
3.  Keep generated-state lineage and compareability intact from `002`.
