chummy/pneumatic-tasking ? reverse-engineered prompt

Build me a Python first InterSystems IRIS interoperability app that runs inside Docker and starts cleanly from a fresh checkout.

Right now it can be a simple placeholder flow, but I want the full project wired up so I can bring up IRIS with docker compose, have the production initialize on startup, and run a basic message flow from a service to a process to an operation. Keep the app easy to edit locally, and make sure changes can be migrated without losing stored data.

Also set up the support pieces the README talks about, like the evidence checks, a health signal, heartbeat metrics, and the optional observability stack for Grafana and Prometheus. Secrets should come from a local .env file, and startup should fail if the password is missing.

If anything is unclear, look up current docs online and then make the implementation work end to end.
