"""Unit: DockerInfraService composes the orchestrator + gateway services.
|
|
|
|
`DockerInfraService` no longer owns the container lifecycles — it composes the
|
|
`DockerOrchestrator` (control plane) and `DockerGateway` (data plane) services,
|
|
each tested in its own module. These tests isolate the *composition*: both are
|
|
built, the orchestrator comes up first, then the gateway is connected to it with
|
|
a freshly minted token."""
