ep_guard_action

Request authorization before an irreversible action: payments, wire transfers, fund releases, deletions, record or account changes, or sending messages with real-world effect. Submits the exact action for policy evaluation and human authorization. This MCP tool does not itself sit at the executor choke point: even after approval, the executor MUST match the returned action_hash and atomically consume the receipt before effect. If BLOCKED, poll ep_check_signoff with the receipt_id.
