GoldKey Action Gate

$0.01 AI-agent tool-call preflight: return ALLOW, REVIEW, or BLOCK before an MCP/tool call, payment, fetch, message, write, or execution. One deterministic request combines prompt-injection and hidden-Unicode scanning, SSRF/unsafe-URL screening, JSON Schema payload validation, and atomic spend-mandate enforcement. Returns stable reason codes plus request_sha256 and receipt_sha256; never executes the action; hashes are reproducible, not signatures.
