Defined in:

Overview

A master Sinatra instance that basically sets up routing to each of the sub-applications, and connects the authorization mechanism.

In the future, we may have status and health check functionality available here.

We mount each application under a “versioned” subpath. This allows us to keep an old and new version of a sub-application in the system at the same time, ideally to allow for migration to breaking changes.
