- Cross-midnight: unfinished yesterday seals ASAP with yesterday's stat_date;
force seal ignores today's snapshot_at gate when stat_date < today.
- Off-plan already_completed: compare completion started_at (not finished_at)
to today's planned slot; earlier → still run at slot for all daily tasks.
- Cold start: bootstrap task:state from task:last / seed markers.
- ensure_pending: do not glue new due onto a different day's unfinished state.
- run_if_needed(force): keep_scraped True for seal, False for CLI --force.
- Scheduler due_reader: pick up disk due_at each loop (seed→evening seal).
Replace process-start next_run=0 guesses with kv task:state records
(status, due_at, stat_date, progress). Startup recovers stale running,
honors future due_at for delayed retries, and resumes the same
stat_date. Seed only enqueues evening seal; seal force keeps non-seed
ok=1 as progress (keep_scraped). Keeps !7 fail-logging and cleanup retry.
