# Checkpoint schedule

Authoritative phase windows for the reality checkpoints
(`research/ScenarioBandMethod.md` § 6). Cron triggers in activity-core cannot
express years, so **every executor run checks this file first**. If today
(Europe/Berlin) is not inside an active window for the run's kind, the
executor records an `out-of-window` no-op and stops.

| Phase | Kind | Window (inclusive) | Dates | Trigger definition |
|---|---|---|---|---|
| baseline | `light` | 2026-10-12 – 2026-10-12 | once, manual trigger (checkpoint 0, ASSEMBLY-WP-0010-T03) | `assembly-checkpoint-setup-daily` |
| setup | `light` | 2026-10-13 – 2026-10-15 | daily | `assembly-checkpoint-setup-daily` |
| transition | `light` | 2026-11-01 – 2026-12-31 | 15th of each month | `assembly-checkpoint-monthly-2026` |
| steady | `light` | from 2027-01-01 | 15 Jan / Apr / Jul / Oct | `assembly-checkpoint-quarterly` |
| steady | `full` | from 2027-01-01 | 20 Jan | `assembly-checkpoint-annual` |

All runs fire at 08:00 Europe/Berlin.

**Housekeeping:** after 2026-12-31, disable `assembly-checkpoint-setup-daily`
and `assembly-checkpoint-monthly-2026` in activity-core (ASSEMBLY-WP-0010-T04).
The window guard above makes a late disable harmless.
