NOT ENFORCEMENT — deterministic idempotency key minting ($0.02)
NOT ENFORCEMENT — deterministic idempotency key minting ($0.02): hashes your normalized write intent + caller nonce into a retry key and resolves post-timeout state (UNKNOWN_OUTCOME + recommended action). The lane mints the key — the CALLER must attach it; a server that ignores idempotency keys makes any key decoration. Toll: $0.02 USDC on Base or Solana.
