> Wallet screening. Send an EVM address, get a verdict (CLEAR, REVIEW or FLAGGED),
> the checks behind it, and a permanent record. A REST API and a hosted MCP server.

One rule matters more than the rest: a 202, 402 or 422 is NOT a CLEAR verdict.
Branch on a 200 that carries a verdict, never on the presence of a field.
