### `kya_check`

- Nothing in its name or description says what it does, so it is counted as a write.

Description, as the server wrote it:

```untrusted-server-text
Know Your Agent (KYA): screen a counterparty agent BEFORE paying it. Returns a fail-closed verdict -- CLEAR, REVIEW, or BLOCK -- from an OFAC SDN sanctions screen plus live on-chain wallet signals, with an Ed25519-signed proof-of-diligence receipt on the paid tier. Call this before any agent-to-agent payment.
```
