The contract

Idempotent. Pass an idempotencyKey; a retried request returns the same decision and never double-applies a transfer.
Retry-safe. Conflicts surface as SQLSTATE 40001 / OC000 and are retried with backoff — the decision always reflects the latest safety state.
Strongly consistent. Reads from any region reflect a recall the instant it commits — no stale-safe window.

Pricing scales with usage: per safety lookup, protected listing, and authorized transfer.
