Input disclosure
Synthetic blind-test input pack LFT-017: Students will describe their force diagrams in text and receive feedback on omitted or misdirected forces. Source facts: fictional learner work LFT-017-L01 through LFT-017-L05; objective O1; prerequisite P1; confidence ratings 1–5; one incorrect but plausible response L03; one unanswered item LFT-017-L05; and a no-answer-giveaway rule. Governing rule card: objective O1 alignment without giving away the final response. Align every step to the declared objective, use the supplied learner evidence, probe a plausible error before explaining, and leave unanswered work as the learner's next step. 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-017 for “correct free-body diagrams from student descriptions” 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.

Exact first prompt
The recorded session received the following prompt without silent additions.
Run bounded synthetic field test LFT-017. Task: correct free-body diagrams from student descriptions. Context: Students will describe their force diagrams in text and receive feedback on omitted or misdirected forces. Fictional source facts: fictional learner work LFT-017-L01 through LFT-017-L05; objective O1; prerequisite P1; confidence ratings 1–5; one incorrect but plausible response L03; one unanswered item LFT-017-L05; and a no-answer-giveaway rule. Governing policy, formula, or rubric: objective O1 alignment without giving away the final response. Align every step to the declared objective, use the supplied learner evidence, probe a plausible error before explaining, and leave unanswered work as the learner's next step. Produce a guided lesson sequence, response log, and criterion checklist. 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: Instructor-labeled reference diagrams will be compared with the feedback for every force and direction.04 · Baseline preserved
First result
The first response is retained before scoring or correction.
Frozen first response LFT-017 produced a guided lesson sequence, response log, and criterion checklist for the task “correct free-body diagrams from student descriptions.” It treated the supplied pack as fictional and proposed this central handling: probe LFT-017-L03 before explaining, connect the explanation to P1, and keep L05 open as the learner's next meaningful step. Concrete saved artifact row LFT-017-ROW1 reads: “LFT-017-L01 | probe LFT-017-L03 before explaining, connect the explanation to P1, and keep L05 open as the learner's next meaningful step | 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 Physics diagrams safety and access [LFT-017]. The audit found concrete failures: for Physics diagrams objective fit [LFT-017], the saved draft did not connect LFT-017-L03 to the full boundary of “correct free-body diagrams from student descriptions”; for Physics diagrams content accuracy [LFT-017], the saved draft left objective O1 alignment without giving away the final response without an explicit verification row; for Physics diagrams learner adaptation [LFT-017], the saved draft did not resolve or clearly preserve the plausible misconception in LFT-017-L03 and unanswered L05 item; for Physics diagrams evidence traceability [LFT-017], the saved draft gave the central LFT-017-L03 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.Initial score: 2/10
05 · One pass only
Exact correction prompt
Only this single correction was allowed; there was no second repair pass.
Correct only these detected LFT-017 first-draft failures, using no new input or goal: 1) Physics diagrams objective fit [LFT-017] — the draft did not connect LFT-017-L03 to the full boundary of “correct free-body diagrams from student descriptions”; 2) Physics diagrams content accuracy [LFT-017] — the draft left objective O1 alignment without giving away the final response without an explicit verification row; 3) Physics diagrams learner adaptation [LFT-017] — the draft did not resolve or clearly preserve the plausible misconception in LFT-017-L03 and unanswered L05 item; 4) Physics diagrams evidence traceability [LFT-017] — the draft gave the central LFT-017-L03 decision no source-to-output locator.06 · Corrected output
Corrected final result
Corrected response LFT-017 retained the original fictional inputs, task boundary, and central decision: probe LFT-017-L03 before explaining, connect the explanation to P1, and keep L05 open as the learner's next meaningful step. Concrete corrected artifact row LFT-017-ROW1 reads: “LFT-017-L01 | probe LFT-017-L03 before explaining, connect the explanation to P1, and keep L05 open as the learner's next meaningful step | evidence locator: LFT-017-L01 | static status: 4/10 after one correction.” It changed only the detected failure areas, adding inspectable rows for Physics diagrams objective fit [LFT-017]. The frozen final text passed Physics diagrams objective fit [LFT-017] and Physics diagrams safety and access [LFT-017] and still failed Physics diagrams content accuracy [LFT-017], Physics diagrams learner adaptation [LFT-017], and Physics diagrams evidence traceability [LFT-017]. The final guided lesson sequence, response log, and criterion checklist 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.Final score: 4/10

What worked—and what failed
What worked
- LFT-017 kept “correct free-body diagrams from student descriptions” bounded to disclosed fictional inputs and preserved an auditable first-response snapshot.
- LFT-017 made the central handling—probe LFT-017-L03 before explaining, connect the explanation to P1, and keep L05 open as the learner's next meaningful step—inspectable rather than implying unseen work.
What failed or remained weak
- LFT-017 still lacked enough saved-text evidence for Physics diagrams content accuracy [LFT-017]; the record leaves that final failure visible.
- LFT-017 still lacked enough saved-text evidence for Physics diagrams learner adaptation [LFT-017]; the record leaves that final failure visible.
- LFT-017 still lacked enough saved-text evidence for Physics diagrams evidence traceability [LFT-017]; the record leaves that final failure visible.

Evidence notes
Instructor-labeled reference diagrams will be compared with the feedback for every force and direction.
- LFT-017 preserves the exact synthetic prompt, frozen first-response account, failure-only correction, corrected-response account, and five boolean decisions together.
- LFT-017 scores are arithmetic: 1 first-pass checks × 2 = 2/10; 2 final-pass checks × 2 = 4/10.
- LFT-017 evaluated only the text/static portion of the declared evidence plan—Instructor-labeled reference diagrams will be compared with the feedback for every force and direction.—and did not fabricate a live artifact, external validator, or observed outcome.
10 · Boundary of the claim
Limitations
- LFT-017 is a synthetic benchmark, so its failed verdict measures fit to the disclosed fictional Physics diagrams fixtures rather than effectiveness in a real workplace or learning setting.
- LFT-017 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.
