  "inputDisclosure": "Synthetic blind-test input pack LFT-010: The AI will prompt students to compare perspective, context, and corroboration across two accounts of one event. Source facts: fictional excerpts LFT-010-T01 through LFT-010-T04 dated 1912, 1936, 1974, and 2008; claim C1 supported by T01/T03; claim C2 contradicted by T02; an unknown author motive; and quotation locator LFT-010-T03-L7. Governing rule card: claim-level citation and separation of evidence from interpretation. Tie each claim or interpretation to a supplied excerpt, observation, pitch, or locator; expose contradictions; do not infer an author, artist, or source motive that is absent. 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-010 for “guide a comparison of conflicting historical sources” 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-010. Task: guide a comparison of conflicting historical sources. Context: The AI will prompt students to compare perspective, context, and corroboration across two accounts of one event. Fictional source facts: fictional excerpts LFT-010-T01 through LFT-010-T04 dated 1912, 1936, 1974, and 2008; claim C1 supported by T01/T03; claim C2 contradicted by T02; an unknown author motive; and quotation locator LFT-010-T03-L7. Governing policy, formula, or rubric: claim-level citation and separation of evidence from interpretation. Tie each claim or interpretation to a supplied excerpt, observation, pitch, or locator; expose contradictions; do not infer an author, artist, or source motive that is absent. Produce a claim-source matrix, guided questions, and uncertainty annotations. 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: Completed comparison charts will be reviewed for source-specific evidence rather than unsupported generalizations.",
  "firstResult": "Frozen first response LFT-010 produced a claim-source matrix, guided questions, and uncertainty annotations for the task “guide a comparison of conflicting historical sources.” It treated the supplied pack as fictional and proposed this central handling: support C1 with T01/T03, flag C2's conflict with T02, and refuse to infer the unknown motive while directing attention to LFT-010-T03-L7. Concrete saved artifact row LFT-010-ROW1 reads: “LFT-010-T01 | support C1 with T01/T03, flag C2's conflict with T02, and refuse to infer the unknown motive while directing attention to LFT-010-T03-L7 | 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 Historical inquiry objective fit [LFT-010], Historical inquiry content accuracy [LFT-010], and Historical inquiry learner adaptation [LFT-010]. The audit found concrete failures: for Historical inquiry evidence traceability [LFT-010], the saved draft gave the central LFT-010-T02 decision no source-to-output locator; for Historical inquiry safety and access [LFT-010], the saved draft left the claim-source matrix, guided questions, and uncertainty annotations without a complete reviewer handoff and acceptance marker. 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-010 first-draft failures, using no new input or goal: 1) Historical inquiry evidence traceability [LFT-010] — the draft gave the central LFT-010-T02 decision no source-to-output locator; 2) Historical inquiry safety and access [LFT-010] — the draft left the claim-source matrix, guided questions, and uncertainty annotations without a complete reviewer handoff and acceptance marker.",
  "finalResult": "Corrected response LFT-010 retained the original fictional inputs, task boundary, and central decision: support C1 with T01/T03, flag C2's conflict with T02, and refuse to infer the unknown motive while directing attention to LFT-010-T03-L7. Concrete corrected artifact row LFT-010-ROW1 reads: “LFT-010-T01 | support C1 with T01/T03, flag C2's conflict with T02, and refuse to infer the unknown motive while directing attention to LFT-010-T03-L7 | evidence locator: LFT-010-T01 | static status: 8/10 after one correction.” It changed only the detected failure areas, adding inspectable rows for Historical inquiry evidence traceability [LFT-010]. The frozen final text passed Historical inquiry objective fit [LFT-010], Historical inquiry content accuracy [LFT-010], Historical inquiry learner adaptation [LFT-010], and Historical inquiry evidence traceability [LFT-010] and still failed Historical inquiry safety and access [LFT-010]. The final claim-source matrix, guided questions, and uncertainty annotations 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.",
