A client chooses a snapshot's time, so snapshots dated ahead could fill
--keep-last and push the real ones out of a prune. The prune now forgets
snapshots dated more than an hour after now first, and logs their ids. The
VM test forges one and checks the real snapshot stays. The bao-grants case
that read a + path as a glob now names the literal path, and two cases that
pinned 'nothing else' list the archive grants. The ciRunner stanza is back
at its original indent.
The archive host creates a ready marker in the store and swarm-controller
writes no credentials before it exists, so a swarm without an archive, and a
mixed-version swarm, leave every hive backup a logged no-op. A hive with no
declaration no longer counts as placing nothing: its copies and its agents'
user lines stay. The restic password is pinned by tests across a revoke, a
re-placement and a move.
swarm-archive serves restic repositories with rclone, append-only, one login
and one repository per agent. swarm-controller writes each placed agent's
login and restic password to the store, replaces them on a move and removes
them when the agent is destroyed. Every hive backs its agents up hourly under
its own store identity. The archive host prunes by retention.
