Wires a 60s server-side ticker to the pure-logic maintenance.Decide
introduced in the previous commit. Decisions flow through a new
DispatchMaintenance method on *Server, which:
- skips offline hosts (no pending_runs queueing — maintenance is
not a backup, missed fires shouldn't pile up)
- silently skips prune when admin creds aren't bound
- pushes admin creds before prune, then dispatches with
RequiresAdminCreds=true (same as operator-driven prune)
- persists job rows with actor_kind="system"
Reshapes the forget wire payload from a single RetentionPolicy to a
ForgetGroups list (one tag + per-group keep-* per source group). The
agent walks the groups and runs `restic forget --tag <name> --keep-*`
once per group. Dead-code removed: CommandRunPayload.RetentionPolicy,
the old forget JSON-decode in cmd/agent, and the single-policy form of
restic.RunForget.
Save and SaveAdmin now propagate loadBundle errors instead of silently
overwriting a corrupt file (data-loss fix). Tests added for both paths.
reportStats logs a Debug on RunStats failure; r in runJob gets a comment
explaining the prune-runner asymmetry; runner_test comment tightened.
RunCheck and RunUnlock were calling sendFinished before reportStats,
inverting the required job.started → log.stream → repo.stats →
job.finished envelope order. Move reportStats ahead of sendFinished in
both functions to match the pattern already correct in RunPrune.
Strengthen TestRunCheckShipsCheckStatus, TestRunCheckErrorsFoundShipsErrorsStatus,
and TestRunUnlockClearsLock with the same position-index ordering
assertions used by TestRunPruneShipsExpectedEnvelopes; these assertions
would have failed against the pre-fix code.
Extract resticEnv/sendStarted/streamHandler/sendFinished helpers to remove
boilerplate duplication across Run* methods. Add RunPrune (ships repo.stats
with LastPruneAt before job.finished), RunCheck (ships stats with
LastCheckStatus/LockPresent regardless of outcome), RunUnlock (ships
LockPresent=false on success), and reportStats (fills size fields via
RunStats when caller didn't populate them).
Wire JobPrune/JobCheck/JobUnlock into the dispatcher switch; teach
MsgConfigUpdate about the Slot discriminator for admin vs repo creds;
add strconv import for subset-pct parsing.
