## Code Comparison With Previous State

*   Compare against `003-agentic-harness-foundation`: [code/generated-state-003-agentic-harness-foundation...code/generated-state-004-containerized-compose-runtime](https://github.com/finos/traderX/compare/code%2Fgenerated-state-003-agentic-harness-foundation...code%2Fgenerated-state-004-containerized-compose-runtime)

## Plain-English Code Delta

*   **Code focus:** Adds Dockerfiles and Compose assembly for all baseline services.
*   **Runtime behavior:** Keeps behavior from state 002 but moves orchestration to containers.
*   **Learning takeaway:** Establishes the containerized baseline that other architecture branches build from.

## Run This State

```bash
./scripts/start-state-004-containerized-generated.sh
