  "description": "Evaluates Swift CBPR+ MT101 message-type retirement readiness ahead of the 2026-11-14 coexistence deadline, when FI-to-FI bulk/multiple payment initiation drops MT101 (FIN) in favor of pain.001v9 (ISO 20022 MX). Caller declares the message format currently in production (MT101 or pain.001v9) and a structural self-declared readiness checklist -- does the sender's system already emit pain.001v9 for bulk FI-to-FI, is a fallback path staged, has the correspondent confirmed it can receive pain.001v9. The kernel deterministically recomputes `ready` and `days_to_deadline` from the fixed deadline constant and a caller-supplied `as_of_date`. Distinct from art-548 (Fedwire/CHIPS structured-address remediation, deadline 2026-11-16, a different sub-mandate one day apart).",
