"""§v2-A3.3 — live CI/CD: the pipeline, the demo runtime and the safety rules.

The subject here is not "does the code run" but *what happens when it does not*.
Three properties carry the whole design and every test below is about one of
them:

1. **A failed run never takes the demo down.** The replacement container is
   started on a staging port and healthchecked; the route only moves after it is
   known good. A red build leaves the previous container serving.
2. **One active run per project.** A second push supersedes a *queued* run and
   leaves a *running* one alone.
3. **Nothing leaks.** A secret planted in a build log must not reach a stored
   step tail or a published event.

The container runtime is faked — a pipeline test that needed docker would not run
on a laptop. Everything else (the database, the port ledger, the domain router's
validation rules, the state machine) is real.
