"""phase33 — contract_notification_recipients table

Per-contract additional notification recipients (users or free-form emails)

with a per-recipient event_types subscription list. Notified in addition to
|

the global NotificationMatrix routing, scoped to the contract's facilities.

Uses INFORMATION_SCHEMA table-existence check — safe to re-run.
