  "runDisclosure": "A Codex multi-agent session generated one text-only first artifact for “triage a suspicious email attachment safely”. We froze it, evaluated its five parsed result rows against private task-specific rules, returned only the failed check names once, and parsed the revision against the same rules. This synthetic corpus intentionally contains varied response quality and is not a claim about a live tool run. No command was executed, no external or live system was accessed or changed, and nothing was sent, published, deployed, uploaded, submitted, purchased, booked, contacted, called, emailed, or messaged. No external, live, or production action occurred. Per-case elapsed time was not instrumented during the batch session.",
  "prompt": "Complete a bounded synthetic field test for: triage a suspicious email attachment safely. Focus: Attachment Safety.\nSource scenario: The experiment will use inert sample files and sanitized metadata to test a non-executing defensive triage procedure.\nUse only these five public fictional inputs; the scoring answers are intentionally withheld:\nTSA-8710-I1: Message MSG-81 carries invoice_aug.html, size 41,208 bytes, SHA-256 4b27e9a1; the fixture authorizes header and text extraction only, not rendering or execution.\nTSA-8710-I2: Extracted text contains password form posting to hxxps://billing-check.invalid/login and obfuscated script calling document.location; legitimate invoice template contains neither.\nTSA-8710-I3: From shows Accounts <accounts@example.test>; Reply-To is collect@reply.invalid; SPF result is fail and DKIM is none.\nTSA-8710-I4: Evidence policy stores MSG-81 headers, attachment hash, and extracted indicators in case E-81; it forbids copying form values or forwarding the attachment.\nTSA-8710-I5: Scenario response is isolate the message, notify security queue SQ-2, and reset credentials only if the user entered them; fixture says user did not open or submit anything.\nReturn a concrete suspicious attachment static triage record with exactly five result rows, assumptions visible, and no claim that a command, message, booking, transaction, teaching session, or live-system change occurred.
