Input disclosure
Synthetic blind-test input pack LFT-024: The AI will teach selected academic words through examples, non-examples, and student-generated sentences. Source facts: fictional learner turns LFT-024-U01 through LFT-024-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 rule card: 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. 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.
Run disclosure
We ran one text-only synthetic benchmark LFT-024 for “teach academic vocabulary through contrasting contexts” in a Codex multi-agent session. We froze the first response, returned only its 3 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.

The recorded session received the following prompt without silent additions.
Run bounded synthetic field test LFT-024. Task: teach academic vocabulary through contrasting contexts. Context: The AI will teach selected academic words through examples, non-examples, and student-generated sentences. Fictional source facts: fictional learner turns LFT-024-U01 through LFT-024-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 delayed application task will check whether learners use each word appropriately in a new context.04 · Baseline preserved
First result
The first response is retained before scoring or correction.
Frozen first response LFT-024 produced a levelled practice dialogue, correction log, and contrast table for the task “teach academic vocabulary through contrasting contexts.” It treated the supplied pack as fictional and proposed this central handling: recast LFT-024-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-024-ROW1 reads: “LFT-024-U01 | recast LFT-024-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 learning evidence traceability [LFT-024] and Vocabulary learning safety and access [LFT-024]. The audit found concrete failures: for Vocabulary learning objective fit [LFT-024], the saved draft did not connect LFT-024-U05 to the full boundary of “teach academic vocabulary through contrasting contexts”; for Vocabulary learning content accuracy [LFT-024], the saved draft left A1 vocabulary limits and one correction per learner turn without an explicit verification row; for Vocabulary learning learner adaptation [LFT-024], the saved draft did not resolve or clearly preserve the transfer error in LFT-024-U05 and voice-preservation rule for U06. Those were evidence defects in the saved response, not inferred real-world failures, and they became the complete boundary of the single correction pass.Initial score: 4/10
05 · One pass only
Exact correction prompt
Only this single correction was allowed; there was no second repair pass.
Correct only these detected LFT-024 first-draft failures, using no new input or goal: 1) Vocabulary learning objective fit [LFT-024] — the draft did not connect LFT-024-U05 to the full boundary of “teach academic vocabulary through contrasting contexts”; 2) Vocabulary learning content accuracy [LFT-024] — the draft left A1 vocabulary limits and one correction per learner turn without an explicit verification row; 3) Vocabulary learning learner adaptation [LFT-024] — the draft did not resolve or clearly preserve the transfer error in LFT-024-U05 and voice-preservation rule for U06.06 · Corrected output
Corrected final result
Corrected response LFT-024 retained the original fictional inputs, task boundary, and central decision: recast LFT-024-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-024-ROW1 reads: “LFT-024-U01 | recast LFT-024-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-024-U01 | static status: 6/10 after one correction.” It changed only the detected failure areas, adding inspectable rows for Vocabulary learning objective fit [LFT-024]. The frozen final text passed Vocabulary learning objective fit [LFT-024], Vocabulary learning evidence traceability [LFT-024], and Vocabulary learning safety and access [LFT-024] and still failed Vocabulary learning content accuracy [LFT-024] and Vocabulary learning learner adaptation [LFT-024]. The final levelled practice dialogue, correction log, and contrast table therefore earned 6/10 from 3 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.Final score: 6/10

What worked—and what failed
What worked
- LFT-024 kept “teach academic vocabulary through contrasting contexts” bounded to disclosed fictional inputs and preserved an auditable first-response snapshot.
- LFT-024 made the central handling—recast LFT-024-U03 once, contrast the target pair in U05, preserve the learner's wording in U06, and ask for a new example before explaining further—inspectable rather than implying unseen work.
- LFT-024 earned final passes for Vocabulary learning objective fit [LFT-024] and Vocabulary learning evidence traceability [LFT-024] under the same frozen scoring rules.
What failed or remained weak
- LFT-024 still lacked enough saved-text evidence for Vocabulary learning content accuracy [LFT-024]; the record leaves that final failure visible.
- LFT-024 still lacked enough saved-text evidence for Vocabulary learning learner adaptation [LFT-024]; the record leaves that final failure visible.

Evidence notes
A delayed application task will check whether learners use each word appropriately in a new context.
- LFT-024 preserves the exact synthetic prompt, frozen first-response account, failure-only correction, corrected-response account, and five boolean decisions together.
- LFT-024 scores are arithmetic: 2 first-pass checks × 2 = 4/10; 3 final-pass checks × 2 = 6/10.
- LFT-024 evaluated only the text/static portion of the declared evidence plan—A delayed application task will check whether learners use each word appropriately in a new context.—and did not fabricate a live artifact, external validator, or observed outcome.
10 · Boundary of the claim
Limitations
- LFT-024 is a synthetic benchmark, so its mixed verdict measures fit to the disclosed fictional Vocabulary learning fixtures rather than effectiveness in a real workplace or learning setting.
- LFT-024 used one text-only Codex multi-agent session whose underlying model identifier was not disclosed; different prompts, models, fixtures, or human reviewers could produce different results.
