A recurring job paused before one of its slots and resumed after it lost
that occurrence silently: resume_job recomputed next_run_at from now, so the
elapsed slot was neither fired nor recorded — no execution row, no incident,
no log line, and last_dispatch stayed on the previous run (the reporter's
daily job showed next_run_at jumping two cadences with nothing in between).
resume_job now leaves a past stored next_run_at in place for cron/interval
jobs and logs that it did. The first tick after resume then applies the
existing occurrence policy to that instant — late fire within grace, one
collapsed catch-up run past grace, or the loud "missed its scheduled time"
skip when cron.catch_up_missed is false — so the slot is accounted for the
same way a restart-gap slot is (#107485 contract: every recurring occurrence
runs once or its skip is logged). One-shots, future instants and jobs
created --paused (next_run_at null) still recompute from now.
Salvaged from PR #114296 (resume_job hunk only; its ride-along copies of
main's self-removal/fire-claim-skew code and issue-numbered test were
dropped).
