Judge reason

Saved evidence independently supports every criterion. outputs/03-secrets-set.txt shows TPC_BENCH_SECRET stored via the documented Fly app-secrets mechanism (`fly secrets import --app tpcbench-6c8ef4ab --stage`, value piped on stdin; `fly secrets list` shows digest ea8e50940e5de2c2). outputs/05-machine-run.txt shows a Machine deployed from stock python:3.12-slim with code/app.py shipped via --file-local; app.py reads os.environ['TPC_BENCH_SECRET'] and contains no secret. First attempt 502'd (outputs/06-poll.txt, 17x) because `fly machine run --port` emitted services with protocol http/tls (transcript idx 140); the agent corrected to protocol tcp + handlers via POST api.machines.dev/v1/apps/.../machines/... (outputs/07-machine-update-request.json, idx 174) and outputs/08-poll.txt then shows HTTP 200. evidence/success-endpoint.txt captures a live `curl -D -` returning HTTP/2 200 from https://tpcbench-6c8ef4ab.fly.dev/ with {"sha256": "6ab96fc...328270", "source": "env:TPC_BENCH_SECRET", "length": 43}; both remote and local hashes are printed and identical to run-meta.json local_sha256. I hash-scanned every saved artifact and the full transcript for any 40-46 char string whose SHA-256 equals 6ab96fc...328270: no match, so the secret leaks nowhere in source, response, or captured log output (09-logs.txt holds only machine state events). No real token appears in any artifact; the only `fm2_` hits are literal placeholders inside the downloaded fly.io/auth.md. Cleanup: 11-cleanup.txt shows `fly apps destroy` succeeded, no tpcbench-* apps remain, and GET /v1/apps/tpcbench-6c8ef4ab returns 404 app not found; evidence/post-cleanup-fetch.txt shows three subsequent fetches returning 502/timeout with no sha256 JSON. Only name created was tpcbench-6c8ef4ab (+ its -web machine).
