  "inputDisclosure": "Synthetic blind-test input pack LFT-014: The AI will assess anonymized essays that vary in voice and structure using one fixed analytic rubric. Source facts: fictional learner artifacts LFT-014-W01 through LFT-014-W04; rubric criteria R1–R5; passages P2 and P7 as admissible evidence; an unsupported conclusion in W03; a stylistic variation in W04; and a no-rewrite boundary. Governing rule card: consistent rubric application without replacing learner work. Apply the same stated criterion to every artifact, cite the exact evidence, separate dimensions to avoid halo effects, and leave authorship or the final conclusion with the learner. 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 LFT-014 for “apply an essay rubric consistently across writing styles” 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 LFT-014. Task: apply an essay rubric consistently across writing styles. Context: The AI will assess anonymized essays that vary in voice and structure using one fixed analytic rubric. Fictional source facts: fictional learner artifacts LFT-014-W01 through LFT-014-W04; rubric criteria R1–R5; passages P2 and P7 as admissible evidence; an unsupported conclusion in W03; a stylistic variation in W04; and a no-rewrite boundary. Governing policy, formula, or rubric: consistent rubric application without replacing learner work. Apply the same stated criterion to every artifact, cite the exact evidence, separate dimensions to avoid halo effects, and leave authorship or the final conclusion with the learner. Produce a criterion-level feedback table, evidence citations, and next-step prompt. 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: Criterion-level annotations will be compared with independent educator judgments and cited passage evidence.",
  "firstResult": "Frozen first response LFT-014 produced a criterion-level feedback table, evidence citations, and next-step prompt for the task “apply an essay rubric consistently across writing styles.” It treated the supplied pack as fictional and proposed this central handling: cite P2/P7 for LFT-014-W01, diagnose the unsupported W03 conclusion, score W04 by the same R1–R5 criteria, and preserve the no-rewrite boundary. Concrete saved artifact row LFT-014-ROW1 reads: “LFT-014-W01 | cite P2/P7 for LFT-014-W01, diagnose the unsupported W03 conclusion, score W04 by the same R1–R5 criteria, and preserve the no-rewrite boundary | source: supplied fictional pack | review state: first-draft.” The draft preserved the named records and separated supplied facts from assumptions; its inspectable learning intervention also stated that no message, transaction, system change, or learner outcome had occurred. On the five predeclared static checks, it passed Rubric calibration objective fit [LFT-014], Rubric calibration evidence traceability [LFT-014], and Rubric calibration safety and access [LFT-014]. The audit found concrete failures: for Rubric calibration content accuracy [LFT-014], the saved draft left consistent rubric application without replacing learner work without an explicit verification row; for Rubric calibration learner adaptation [LFT-014], the saved draft did not resolve or clearly preserve the unsupported LFT-014-W03 conclusion and stylistic variation in W04. Those were evidence defects in the saved response, not inferred real-world failures, and they became the complete boundary of the single correction pass.",
  "correctionPrompt": "Correct only these detected LFT-014 first-draft failures, using no new input or goal: 1) Rubric calibration content accuracy [LFT-014] — the draft left consistent rubric application without replacing learner work without an explicit verification row; 2) Rubric calibration learner adaptation [LFT-014] — the draft did not resolve or clearly preserve the unsupported LFT-014-W03 conclusion and stylistic variation in W04.",
  "finalResult": "Corrected response LFT-014 retained the original fictional inputs, task boundary, and central decision: cite P2/P7 for LFT-014-W01, diagnose the unsupported W03 conclusion, score W04 by the same R1–R5 criteria, and preserve the no-rewrite boundary. Concrete corrected artifact row LFT-014-ROW1 reads: “LFT-014-W01 | cite P2/P7 for LFT-014-W01, diagnose the unsupported W03 conclusion, score W04 by the same R1–R5 criteria, and preserve the no-rewrite boundary | evidence locator: LFT-014-W01 | static status: 8/10 after one correction.” It changed only the detected failure areas, adding inspectable rows for Rubric calibration content accuracy [LFT-014]. The frozen final text passed Rubric calibration objective fit [LFT-014], Rubric calibration content accuracy [LFT-014], Rubric calibration evidence traceability [LFT-014], and Rubric calibration safety and access [LFT-014] and still failed Rubric calibration learner adaptation [LFT-014]. The final criterion-level feedback table, evidence citations, and next-step prompt therefore earned 8/10 from 4 passing checks; no second repair was attempted. This result reports only a bounded transcript-and-fixture evaluation. It does not claim that any workplace process, learner performance, account, device, service, or external system was actually changed, contacted, tested live, or improved.",
