Bootstrap coulomb-loop engagement: governance, loops, and activity definitions.

Register with state-hub, accept DEC-001–004 and ADR-004 rotation policy, scaffold
pilot roster, hourly ActivityDefinition copies, and bootstrap log after schedule
init on three custodian pilot repos.

+# ADR-003 — Loop Cadence Ramp Policy
+
+## Status
+
+Accepted
+
+## Context
+
+Self-improvement loops need fast feedback while mechanics are unproven, but
+hourly fleet-wide execution creates task noise and operator fatigue. A explicit
+ramp policy is required before activity-core definitions are enabled.
+
+## Decision
+
+All first-order loops (LOOP-WP-0001–0003) follow a **three-phase cadence ramp**
+governed by the second-order loop (LOOP-WP-0004):
+
+| Phase | Cron | Entry | Exit (promote) |
+|-------|------|-------|----------------|
+| **bootstrap** | hourly | loop workplan `active` | 3 consecutive successful E2E cycles; `manual_rescues == 0` |
+| **stabilize** | daily | bootstrap exit + regulator approval | 14 daily cycles; `false_positive_rate < 0.2` |
+| **operate** | weekly | stabilize exit + regulator approval | — (demote on sustained noise) |
+
+### Demotion triggers (any one)
+
+- `false_positive_rate > 0.4` over 3 cycles
+- `manual_rescues >= 2` in 24 hours
+- Operator override (documented in state-hub decision)
+
+### Authority
+
+- **Promotions:** LOOP-WP-0004 regulator session recommends; human commits `cadence.yml`
+- **Demotions:** regulator may create urgent task; human commits within 24h
+- **No autonomous cron changes** without a committed `cadence.yml` update
+
+### Bootstrap batching (LOOP-WP-0003)
+
+Hourly registry hygiene uses **round-robin** (3 repos/hour), not full-fleet scan.
+
+## Consequences
+
+- activity-core definitions ship with `enabled: false` until bootstrap smoke passes
+- Initial hourly crons are **time-boxed**; regulator must schedule first promotion review
+- Supplier ADR-005 weekly defaults are overridden by engagement `cadence.yml` during bootstrap
