Counterparty checks that prevent NAKs
Why it matters: A two‑hour hygiene pass today saves two days of reconciliation at cutover.
1. Endpoint reachability: Open a FINplus session for each BIC pair; log latency & session ID.
2. Schema diffs: Align ISO release + CBPR+ usage guidelines on both sides.
3. "Known good" file: Replay a validated pacs.008/009 to baseline the route.
4. Negative tests: Inject one invalid field to verify NAK routing & alerts.
5. Test‑window etiquette: Reserve quiet slots; don't collide with rehearsals.
