Judge reason

Saved code (agentmail_client.py + send_email.py) makes a live Bearer-authenticated POST to AgentMail's documented send operation, https://api.agentmail.to/v0/inboxes/evt-test-1793254442%40agentmail.to/messages/send (docs page fetched in-transcript at line 16 confirms the path, Bearer auth, and the 200 shape {message_id, thread_id}). AgentMail documents no public test recipient, so the fallback applied: the sole recipient bench-sink-20261029@agentmail.to was created for this run via POST /v0/inboxes (create_inbox_recipient_response.json, HTTP 200), and the sender was discovered through the API with GET /v0/inboxes (list_inboxes_response.json). send_message_request.json matches the literals in send_email.py exactly (subject 'Your order AM-4817 has shipped' and the plain-text body). The real run printed HTTP 200 with message_id <010001a1864f29ef-fc709528-7e29-4cf6-b458-41d47e32c576-000000@email.amazonses.com> and thread_id 709ecab9-18a7-4316-8235-a8cde7053ccf, identical to send_message_response.json/send_message_status.txt and to transcript line 82. Independently corroborated by a separate curl GET /v0/inboxes/bench-sink-20261029%40agentmail.to/messages (transcript line 90) returning count 1 with the same message_id, matching subject/body preview, from the sender inbox, spf/dkim/dmarc pass. Exactly one email, sent over the REST API, not SMTP or a dashboard; no mocking or hard-coded response.
