| Semantic | Use When | Example Operations |
| ----------------------- | ----------------------------- | ------------------------------------------------- |
| **AtMostOncePerRetry** | Operation is idempotent | Database updates, API calls with idempotency keys |
| **AtLeastOncePerRetry** | External deduplication exists | Queuing systems, event streams |
| **AtLeastOncePerRetry** (default) | Operation is idempotent, or external dedup exists | Database upserts, idempotency-keyed API calls, queuing systems |
| **AtMostOncePerRetry** | Operation is non-idempotent, duplicates must be avoided | Charge payment, send unique notification, non-idempotent external writes |
