API SpecificationApps

Activation (A2): the public "starts on first request" API. AcquireInstance returns a ready instance, cold-starting one if none exists and blocking up to wait_ms; ReportLoad feeds idle-reap without an RPC per HTTP request.

POST
/containers.api.v1.AppService/AcquireInstance

With an App now routable by hostname, AcquireInstance is no longer on the request path for a caller that just wants to reach the app — the proxy does it. It stays public for warmup: starting an instance at promote time, before any user request arrives.

Authorization
