A read could start a state's watch before its follower joined, and a change landing in that gap woke nothing (review
of ADR 0580 §2): a joining follower now runs over the copy's current values before any later change. The watched
reader keeps each archive once per URL, and both caches are bounded.

A whole state read key by key took the provisioner's composition of one node past 30 s and the assigner's compare past
its call bound (ADR 0580 clause 1): each state is now one watch's current values, kept by its changes; a build is read
by key and a manifest once per digest.
