# DEC-005 — Kaizen Stack Cadence Promotion

**Status:** accepted
**Date:** 2026-06-18
**Owner:** Bernd (Coulomb operator)
**Workplan:** LOOP-WP-0001 T08, LOOP-WP-0004 T06

---

## Decision

Promote **kaizen-improvement-stack** from `bootstrap` (hourly) to `stabilize` (daily).

## Evidence

- 3/3 consecutive hourly E2E cycles across pilot roster (see `loops/kaizen-stack/bootstrap-log.md`)
- `manual_rescues == 0`
- activity-core `activity_runs` show 6+3+3 tasks per cycle
- Session-close metrics on all 3 pilots

## New cadence (Europe/Berlin)

| Step | Cron |
|------|------|
| metrics optimize | `0 8 * * *` |
| coach orientation | `0 9 * * *` |
| optimization review | `0 10 * * *` |

Updated: pilot `schedule.yml`, `loops/kaizen-stack/cadence.yml`, activity-definitions, Temporal schedules.
