## Known failure modes

- Invalid beer slug — returns error if the slug doesn't match any item from GET /cantina/menu
- Note exceeds 280 characters — validation error returned
- patron_id or signed_as exceed character limits (128 and 64 chars respectively) — rejected with schema validation error
- Payment failure — x402 micropayment of $0.25 USDC not completed, round not queued
- No upcoming patrons available — round may be queued but not immediately delivered
