Primes

• Idempotence
  • Square's similar primitive, and PayPal's RequestId make a fundamentally non-idempotent operation (charging a card) safe under retry by maintaining a server-side dedup cache keyed by (idempotency key, account) for at least 24 hours.

    This sourceDocuments the `Idempotency-Key` HTTP header pattern, server-side dedup cache with at-least-24-hour retention, and the `(account_id, idempotency_key)` keying scheme for deduplication. (Industry-standard pattern for engineered idempotence over POST-style APIs; widely copied by Square, PayPal, and other payment processors.)
