🟢ausca_agent_inbox_attachment(attachment_id, idempotency_key, inbox_id, message_id)
For an active inbox, return an idempotent download URL only when the exact stored attachment has a clean safety verdict. The URL expires after at most 60 seconds and never after inbox expiry; a clean verdict does not make the attachment content trusted. Supply the lease bearer on the HTTP or MCP transport; never place it in tool arguments.
