CAIN-42 soak on the live multi-region cluster cain-mr-01: soak-multiregion-2026-09-26

Planned: 72.0 h. Every 1200 s a random replica is killed on its own host for 60 s.
Hourly checkpoints are hash-chained and signed with the CAIN-42 evidence-root key.

Verify (Python 3.8+, pip install cryptography, no CAIN code):
