"""Pipeline runs, the webhook and live archive events keep to what each user may see.

A pipeline run's queue jobs and source belong to the user who started it. The
run shows another user neither its source nor its queue jobs, and only someone
who may change those jobs cancels or clears it. A webhook key acts for its
owner: it starts only a job its owner could start, and lists only the jobs its
owner sees. A live archive event says only that an archive on a printer
changed.
