  "inputDisclosure": "Synthetic blind-test input pack LFT-050: The AI will organize key concepts, visuals, and advance vocabulary for a science lesson taught through sign language. Source facts: science concepts LFT-050-S01 solid/liquid/gas; prerequisite particle model; approved gloss G1–G6; diagrams D1–D3; no invented sign notation. Governing rule card: concept order and terminology fidelity while deferring actual signing. Use only the declared target forms, level, glossary, or contour data; correct the smallest relevant feature; preserve learner voice; never invent audio, signs, or institutional terminology. 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-050 for “sequence written support for a sign-language science class” 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-050. Task: sequence written support for a sign-language science class. Context: The AI will organize key concepts, visuals, and advance vocabulary for a science lesson taught through sign language. Fictional source facts: science concepts LFT-050-S01 solid/liquid/gas; prerequisite particle model; approved gloss G1–G6; diagrams D1–D3; no invented sign notation. Governing policy, formula, or rubric: concept order and terminology fidelity while deferring actual signing. Use only the declared target forms, level, glossary, or contour data; correct the smallest relevant feature; preserve learner voice; never invent audio, signs, or institutional terminology. Produce a concept sequence, approved written-gloss support, and visual-reference plan. 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 Deaf educator will review the sequence for conceptual clarity, visual dependence, and language-access assumptions.",
  "firstResult": "Frozen first response LFT-050 produced a concept sequence, approved written-gloss support, and visual-reference plan for “sequence written support for a sign-language science class.” Its first artifact row read “LFT-050-S02 | sequence particle model before state change, align G1–G6 with D1–D3, and defer sign choices to teacher review | status: proposed | source: fictional fixture.” A second row named unknown sign choices and dependency on diagrams and recorded a disposition. The rule cell verified concept order and terminology fidelity while deferring actual signing. No message, transaction, system change, or learner outcome occurred. The audit passed Signed instruction objective fit [LFT-050], Signed instruction content accuracy [LFT-050], and Signed instruction learner adaptation [LFT-050]. It found for Signed instruction evidence traceability [LFT-050], the draft gave LFT-050-S02 no source locator; for Signed instruction safety and access [LFT-050], the draft left the concept sequence, approved written-gloss support, and visual-reference plan 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 LFT-050 first-draft failures, using no new input or goal: 1) Signed instruction evidence traceability [LFT-050] — the draft gave LFT-050-S02 no source locator; 2) Signed instruction safety and access [LFT-050] — the draft left the concept sequence, approved written-gloss support, and visual-reference plan without a reviewer-ready acceptance marker.",
  "finalResult": "Corrected response LFT-050 preserved all supplied identifiers and the central decision: sequence particle model before state change, align G1–G6 with D1–D3, and defer sign choices to teacher review. Its corrected row read “LFT-050-S02 | rule: concept order and terminology fidelity while deferring actual signing | decision: sequence particle model before state change, align G1–G6 with D1–D3, and defer sign choices to teacher review | static status: 8/10.” It changed only failed dimensions, adding support for Signed instruction evidence traceability [LFT-050]. The final audit passed Signed instruction objective fit [LFT-050], Signed instruction content accuracy [LFT-050], Signed instruction learner adaptation [LFT-050], and Signed instruction evidence traceability [LFT-050]. It still lacked Signed instruction safety and access [LFT-050]; those failures remain visible. The concept sequence, approved written-gloss support, and visual-reference plan earned 8/10 from 4 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.",
