  "runDisclosure": "We ran one text-only synthetic benchmark LFT-062 for “create contextual vocabulary practice for a fixed word list” 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-062. Task: create contextual vocabulary practice for a fixed word list. Context: A teacher will provide target words, senses, grade level, prohibited distractor patterns, and examples of authentic usage. Fictional source facts: fictional learner turns LFT-062-U01 through LFT-062-U06; target forms 'quiero', 'pero/perro', and 'record/recordar'; beginner level A1; two deliberate transfer errors in U03/U05; and a do-not-rewrite constraint for U06. Governing policy, formula, or rubric: A1 vocabulary limits and one correction per learner turn. 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 levelled practice dialogue, correction log, and contrast table. 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 sense-level audit will verify natural context, target meaning, distractor plausibility, reading level, and answer uniqueness.",
  "firstResult": "Frozen first response LFT-062 produced a levelled practice dialogue, correction log, and contrast table for the task “create contextual vocabulary practice for a fixed word list.” It treated the supplied pack as fictional and proposed this central handling: recast LFT-062-U03 once, contrast the target pair in U05, preserve the learner's wording in U06, and ask for a new example before explaining further. Concrete saved artifact row LFT-062-ROW1 reads: “LFT-062-U01 | recast LFT-062-U03 once, contrast the target pair in U05, preserve the learner's wording in U06, and ask for a new example before explaining further | 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 Vocabulary Practice objective fit [LFT-062], Vocabulary Practice content accuracy [LFT-062], and Vocabulary Practice safety and access [LFT-062]. The audit found concrete failures: for Vocabulary Practice learner adaptation [LFT-062], the saved draft did not resolve or clearly preserve the transfer error in LFT-062-U05 and voice-preservation rule for U06; for Vocabulary Practice evidence traceability [LFT-062], the saved draft gave the central LFT-062-U05 decision no source-to-output locator. 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-062 first-draft failures, using no new input or goal: 1) Vocabulary Practice learner adaptation [LFT-062] — the draft did not resolve or clearly preserve the transfer error in LFT-062-U05 and voice-preservation rule for U06; 2) Vocabulary Practice evidence traceability [LFT-062] — the draft gave the central LFT-062-U05 decision no source-to-output locator.",
  "finalResult": "Corrected response LFT-062 retained the original fictional inputs, task boundary, and central decision: recast LFT-062-U03 once, contrast the target pair in U05, preserve the learner's wording in U06, and ask for a new example before explaining further. Concrete corrected artifact row LFT-062-ROW1 reads: “LFT-062-U01 | recast LFT-062-U03 once, contrast the target pair in U05, preserve the learner's wording in U06, and ask for a new example before explaining further | evidence locator: LFT-062-U01 | static status: 8/10 after one correction.” It changed only the detected failure areas, adding inspectable rows for Vocabulary Practice learner adaptation [LFT-062]. The frozen final text passed Vocabulary Practice objective fit [LFT-062], Vocabulary Practice content accuracy [LFT-062], Vocabulary Practice learner adaptation [LFT-062], and Vocabulary Practice safety and access [LFT-062] and still failed Vocabulary Practice evidence traceability [LFT-062]. The final levelled practice dialogue, correction log, and contrast table 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.",
