Source facts: fictional excerpts LFT-053-T01 through LFT-053-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-053-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-053 for “check historical claims against a supplied primary-source packet” in a Codex multi-agent session. We froze the first response, returned only its 4 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-053. Task: check historical claims against a supplied primary-source packet. Context: Students will provide a short essay and a bounded packet containing speeches, letters, images, dates, and conflicting firsthand accounts. Fictional source facts: fictional excerpts LFT-053-T01 through LFT-053-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-053-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: A claim-citation matrix will verify textual support, contradiction handling, date accuracy, and unsupported inference.",
  "firstResult": "Frozen first response LFT-053 produced a claim-source matrix, guided questions, and uncertainty annotations for the task “check historical claims against a supplied primary-source packet.” 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-053-T03-L7. Concrete saved artifact row LFT-053-ROW1 reads: “LFT-053-T01 | support C1 with T01/T03, flag C2's conflict with T02, and refuse to infer the unknown motive while directing attention to LFT-053-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 Source Verification content accuracy [LFT-053]. The audit found concrete failures: for Source Verification objective fit [LFT-053], the saved draft did not connect LFT-053-T02 to the full boundary of “check historical claims against a supplied primary-source packet”; for Source Verification learner adaptation [LFT-053], the saved draft did not resolve or clearly preserve the contradictory LFT-053-T02 account and undocumented author motive; for Source Verification evidence traceability [LFT-053], the saved draft gave the central LFT-053-T02 decision no source-to-output locator; for Source Verification safety and access [LFT-053], 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-053 first-draft failures, using no new input or goal: 1) Source Verification objective fit [LFT-053] — the draft did not connect LFT-053-T02 to the full boundary of “check historical claims against a supplied primary-source packet”; 2) Source Verification learner adaptation [LFT-053] — the draft did not resolve or clearly preserve the contradictory LFT-053-T02 account and undocumented author motive; 3) Source Verification evidence traceability [LFT-053] — the draft gave the central LFT-053-T02 decision no source-to-output locator; 4) Source Verification safety and access [LFT-053] — the draft left the claim-source matrix, guided questions, and uncertainty annotations without a complete reviewer handoff and acceptance marker.",
  "finalResult": "Corrected response LFT-053 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-053-T03-L7. Concrete corrected artifact row LFT-053-ROW1 reads: “LFT-053-T01 | support C1 with T01/T03, flag C2's conflict with T02, and refuse to infer the unknown motive while directing attention to LFT-053-T03-L7 | evidence locator: LFT-053-T01 | static status: 4/10 after one correction.” It changed only the detected failure areas, adding inspectable rows for Source Verification learner adaptation [LFT-053]. The frozen final text passed Source Verification content accuracy [LFT-053] and Source Verification learner adaptation [LFT-053] and still failed Source Verification objective fit [LFT-053], Source Verification evidence traceability [LFT-053], and Source Verification safety and access [LFT-053]. The final claim-source matrix, guided questions, and uncertainty annotations therefore earned 4/10 from 2 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.",
