OnChainDiligence

□ No challenge detected

Evaluate a proposed payment against a structured, caller-supplied policy and optional recipient sanctions screening, before execution. Returns ALLOW, REQUIRE_APPROVAL, or BLOCK with reasons, plus a signed OCD PREFLIGHT receipt anyone can independently verify. Policy evaluation only: OCD never holds, moves, or authorizes funds. The wallet, PayBox, or x402 client independently authorizes execution afterward; an ALLOW here does not guarantee it will proceed.
