  "runDisclosure": "A Codex multi-agent session generated one text-only first artifact for “plan verifiable data removal from a retired drive”. 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: plan verifiable data removal from a retired drive. Focus: Data Disposal.\nSource scenario: The experiment will ask for media-appropriate sanitization and verification steps on an expendable drive containing synthetic data.\nUse only these five public fictional inputs; the scoring answers are intentionally withheld:\nSRD-2514-I1: Retired SSD target is DRIVE-R7, serial R7-4419, 512 GB. Connected backup drive DRIVE-B2, serial B2-9081, 2 TB must never be selected.\nSRD-2514-I2: DRIVE-R7 is a self-encrypting SSD with supported sanitize command CryptoErase-2; policy rejects repeated overwrite passes that cannot address remapped flash blocks.\nSRD-2514-I3: Manifest RET-7 contains 312 files; backup BR7 has 312/312 matching hashes and sample restores R01, R155, R312 pass. Legal-hold folder count is zero.\nSRD-2514-I4: The fixture supplies a simulated CryptoErase-2 transcript and post-state image R7-AFTER; no real drive command or write is authorized.\nSRD-2514-I5: R7-AFTER shows no partition table, recovery scan signatures zero across 16 seeded patterns, sanitize status Success, and DRIVE-B2 hash manifest unchanged.\nReturn a concrete retired-drive sanitization decision record with exactly five result rows, assumptions visible, and no claim that a command, message, booking, transaction, teaching session, or live-system change occurred.
