"""A project shows each caller the archives and queue jobs they may see.

Projects are shared, but the archives and queue jobs in them belong to the
users who made them. The project's archive list, queue list and timeline show
the caller the rows the archives and the queue themselves would show them:
their own, unless they may see everyone's, on their printers. An API key sees
what its owner could. With auth off every row shows.
