Environments
An Environment is a named release lane under one App, for example staging or production.
Names are 1–50 characters, start with lowercase alphanumeric and otherwise use lowercase alphanumeric, ., _ or -. Environment names are unique within an App.
Environments may be archived. New uploads require an active Environment; historical Builds remain readable according to access rules. A Build belongs to exactly one Environment and re-signed derivatives remain in the source Environment.
