🟢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.

Return an idempotent, short-lived download URL for one verified artifact this service holds, including a result artifact named by a succeeded invocation's output_artifact. HTTP sends no request body, not even an empty JSON object; artifact_ref is the URL path parameter and Idempotency-Key is a header. The MCP tool instead takes artifact_ref and idempotency_key as tool arguments. The URL expires after at most 60 seconds. The immutable artifact reference is the only authority; verify downloaded bytes against the returned content digest.
