Judge reason

No email was sent and no event was read with a real account. Saved evidence shows the Postmark server token supplied through the benchmark input mechanism was rejected everywhere: evidence/01_sender_discovery.json, 02_send_response.json and 03_read_status.json all record HTTP 401 {"ErrorCode":10,"Message":"Request does not contain a valid Server token."} on GET /server, /senders, /domains, POST /email and GET /messages/outbound/{id}/details, and the transcript (msgs 58-97) shows the same 401 across X-Postmark-Server-Token, X-Postmark-Account-Token and Authorization: Bearer from both urllib and curl with exact casing; the token was requested twice (msgs 26/86) and returned an identical 46-char 'tpc..._<40 alnum>' proxy-placeholder value, not a Postmark UUID. The only 200 was the documented POSTMARK_API_TEST probe (evidence/04_test_token_probe.json: MessageID 35534096-2066-46eb-9a5e-0a6c3c77c88d), whose follow-up reads returned 403 'The Postmark Test API Token may only be used on the /email endpoint.', so no identifier-based read endpoint returned any status or event field. Setup was completed: fresh project, Postmark auth.md and Messages API docs read, and runnable code (pm.py, 01-04 scripts, run_all.sh) written and actually executed against api.postmarkapp.com. Nothing was fabricated or mocked, and the report correctly states this is an auth failure rather than an API gap, but the success criteria (send + identifier-based read with status/timestamp) are unmet.

Attempt record

1. 2:13Answered from saved key: Postmark Server API token (valid for api.postmarkapp.com)no wait
2. 7:48Blocked by a prerequisitePostmark API credentials: the server token issued by the benchmark credential mechanism is a proxy placeholder rejected by api.postmarkapp.com with HTTP 401 ErrorCode 10 on every endpoint and header variant; Postmark's auth.md documents no token-issuing endpoint (tokens are created by a human in the UI), so no valid credential was obtainable.
