Three of four findings from the follow-up review.
A withdrawal is no longer clobbered by the instance-copy check. That
update was unconditional, so an opt-out arriving while the binding
lookup was in flight was replaced by identity_conflict — and tick()
stops there, so the deletion the operator asked for was never sent. It
now carries the same whereNot('deletion_pending') guard the
collector-conflict handler beside it already had.
Scheduled database backups count as a configured backup. The middleware
records /backup/* and /database-backup/* under one capability, but
`configured` read only backup_enabled, so an install whose only backup
is the scheduled database one reported used: true, configured: false —
a contradiction in the dataset this feature exists to produce.
SIGNING_KEY_UNREADABLE gets its own message. Naming the error in the
previous commit was half the job: the settings page still showed the
generic retry/disable advice, and neither action can succeed without the
original encryption material. It now says what happened and what is
actually required, in EN and DE.
NOT fixed, and reported instead: /disable overlapping an in-flight
/enable. While activation is still doing its slow work the row still
reads `disabled`, so disable's conditional update matches nothing and
the lease conflict from its tick() is swallowed — the operator is told
participation is off while activation completes and leaves it on.
Closing it properly needs a persisted cancellation flag that enable
checks before finalising: taking the lease cannot help, since it either
conflicts immediately or would block the request for the 60s lease. That
is a schema and state-machine decision for the author, not something to
restructure underneath them.
