A host-agnostic ticker (Tick = one pass; Loop = run on an interval until ctx
done) that fires due jobs. Every dependency is wired by the host:
- Due lists due jobs (skill.ListDueScheduled / persona.ListScheduledAgents),
- Run executes one (run.Executor),
- Mark stamps the next fire (store.MarkScheduledRun),
- Next computes the cron next-fire (a cron lib / skill's parser).
The battery owns NO cron grammar, so it never duplicates the parser. A job whose
Run or Next errors is logged and left un-stamped (stays due, retries next tick)
— one bad job can't stall the others; only a failing Due lister is pass-fatal.
Tests: due jobs run + stamped, bad-cron job runs but isn't stamped, a failing
Run doesn't stamp or stall siblings, Due error surfaces. Core imports ZERO.
