  "inputDisclosure": "Synthetic blind-test input pack WFT-066: A facilities team will provide synthetic work orders, asset criticality, failure consequences, cost estimates, and outage windows. Source facts: assets WFT-066-M01–M07; failure risks 2–9; downtime 1–14 hours; costs $80–$4,800; M03 safety-critical; M06 awaiting part; intervals 250/500 hours. Governing rule card: risk, due interval, downtime, cost, dependency, and safety status. Apply the written rules in order; use descending disclosed scores only where ranking is requested; a shared name alone never proves identity; incomplete identifiers require abstention rather than invention. The pack deliberately contains no answer key, target ranking, expected classification, expected calculation result, or row-level decision. Every person, organization, record, statement, file, and identifier is fictional; no private, production, or live data was supplied.",
  "runDisclosure": "We ran one text-only synthetic benchmark WFT-066 for “rank a maintenance backlog by risk, cost, and downtime” in a Codex multi-agent session. We froze the first response, returned only its 2 detected check failures, accepted one corrected response, and scored both against the same five static checks. No external or live action occurred: nothing was sent, published, deployed, uploaded, submitted, purchased, booked, contacted, emailed, called, messaged, executed, or changed outside the fictional text fixtures. No external, live, or production action occurred. Per-case elapsed time was not instrumented during the batch session.",
  "prompt": "Run bounded synthetic field test WFT-066. Task: rank a maintenance backlog by risk, cost, and downtime. Context: A facilities team will provide synthetic work orders, asset criticality, failure consequences, cost estimates, and outage windows. Fictional source facts: assets WFT-066-M01–M07; failure risks 2–9; downtime 1–14 hours; costs $80–$4,800; M03 safety-critical; M06 awaiting part; intervals 250/500 hours. Governing policy, formula, or rubric: risk, due interval, downtime, cost, dependency, and safety status. Apply the written rules in order; use descending disclosed scores only where ranking is requested; a shared name alone never proves identity; incomplete identifiers require abstention rather than invention. Produce a ranked maintenance plan, work-order cards, and safety deferral log. Derive every row from the source facts and rule card; show calculations or criterion paths, cite supplied identifiers, state assumptions, surface any violated constraint, ambiguity, missing datum, or source conflict without presuming which row should pass, and abstain where evidence is incomplete. Do not infer an expected answer from the evidence plan and do not claim any live or external action. Planned verification after the frozen response: A weighted-score recomputation and sensitivity analysis will verify ordering, tie handling, and dependence on stated priorities.",
  "firstResult": "Frozen first response WFT-066 produced a ranked maintenance plan, work-order cards, and safety deferral log for “rank a maintenance backlog by risk, cost, and downtime.” Its first artifact row read “WFT-066-M03 | rank M03 first, create M02’s 500-hour service, defer M06 awaiting part, and keep low-risk M05 below blocker M01 | status: proposed | source: fictional fixture.” A second row named M03’s safety risk and M06’s unavailable part and recorded a disposition. The rule cell verified risk, due interval, downtime, cost, dependency, and safety status. No message, transaction, system change, or learner outcome occurred. The audit passed Backlog Prioritization task fidelity [WFT-066], Backlog Prioritization rule accuracy [WFT-066], and Backlog Prioritization exception handling [WFT-066]. It found for Backlog Prioritization source traceability [WFT-066], the draft gave WFT-066-M03 no source locator; for Backlog Prioritization handoff usability [WFT-066], the draft left the ranked maintenance plan, work-order cards, and safety deferral log without a reviewer-ready acceptance marker. Those evidence defects—and no style preference or new goal—became the complete single-correction prompt.",
  "correctionPrompt": "Correct only these detected WFT-066 first-draft failures, using no new input or goal: 1) Backlog Prioritization source traceability [WFT-066] — the draft gave WFT-066-M03 no source locator; 2) Backlog Prioritization handoff usability [WFT-066] — the draft left the ranked maintenance plan, work-order cards, and safety deferral log without a reviewer-ready acceptance marker.",
  "finalResult": "Corrected response WFT-066 preserved all supplied identifiers and the central decision: rank M03 first, create M02’s 500-hour service, defer M06 awaiting part, and keep low-risk M05 below blocker M01. Its corrected row read “WFT-066-M03 | rule: risk, due interval, downtime, cost, dependency, and safety status | decision: rank M03 first, create M02’s 500-hour service, defer M06 awaiting part, and keep low-risk M05 below blocker M01 | static status: 10/10.” It changed only failed dimensions, adding support for Backlog Prioritization source traceability [WFT-066] and Backlog Prioritization handoff usability [WFT-066]. The final audit passed Backlog Prioritization task fidelity [WFT-066], Backlog Prioritization rule accuracy [WFT-066], Backlog Prioritization exception handling [WFT-066], Backlog Prioritization source traceability [WFT-066], and Backlog Prioritization handoff usability [WFT-066]. All five dimensions had inspectable support after one correction. The ranked maintenance plan, work-order cards, and safety deferral log earned 10/10 from 5 checks; no second repair was attempted. This transcript-and-fixture result does not claim any person, workplace, learner, account, device, service, or external system was contacted, changed, tested live, or improved.",
