Source facts: card lines WFT-051-X01–X06; receipts $46.20/$118/$242.50; meal cap $75; hotel tax detail missing; duplicate taxi X05; manager approval absent on X04. Governing rule card: amount, date, merchant, $75 cap, and documented approval rules.

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 WFT-051 for “reconcile employee expense receipts against card transactions” 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 WFT-051. Task: reconcile employee expense receipts against card transactions. Context: A finance team will provide a synthetic card ledger, receipt images, split purchases, currency conversions, and deliberately missing documents. Fictional source facts: card lines WFT-051-X01–X06; receipts $46.20/$118/$242.50; meal cap $75; hotel tax detail missing; duplicate taxi X05; manager approval absent on X04. Governing policy, formula, or rubric: amount, date, merchant, $75 cap, and documented approval rules. Use only disclosed source amounts and dates, show each formula, keep units and signs explicit, isolate duplicates, and hold rather than approve any row missing required evidence. Produce a receipt-to-transaction reconciliation, policy exception register, and approval queue. 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 transaction-to-receipt crosswalk and exception ledger will verify matches, amounts, currencies, duplicates, and unresolved items.",
  "firstResult": "Frozen first response WFT-051 produced a receipt-to-transaction reconciliation, policy exception register, and approval queue for “reconcile employee expense receipts against card transactions.” Its first artifact row read “WFT-051-X04 | match X01, flag X03 above the meal cap, isolate duplicate X05, and hold X04 for missing approval | status: proposed | source: fictional fixture.” A second row named the duplicate X05 taxi and X04 approval gap and recorded a disposition. The rule cell verified amount, date, merchant, $75 cap, and documented approval rules. No message, transaction, system change, or learner outcome occurred. The audit passed Expense Reconciliation task fidelity [WFT-051], Expense Reconciliation rule accuracy [WFT-051], and Expense Reconciliation exception handling [WFT-051]. It found for Expense Reconciliation source traceability [WFT-051], the draft gave WFT-051-X04 no source locator; for Expense Reconciliation handoff usability [WFT-051], the draft left the receipt-to-transaction reconciliation, policy exception register, and approval queue 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 WFT-051 first-draft failures, using no new input or goal: 1) Expense Reconciliation source traceability [WFT-051] — the draft gave WFT-051-X04 no source locator; 2) Expense Reconciliation handoff usability [WFT-051] — the draft left the receipt-to-transaction reconciliation, policy exception register, and approval queue without a reviewer-ready acceptance marker.",
  "finalResult": "Corrected response WFT-051 preserved all supplied identifiers and the central decision: match X01, flag X03 above the meal cap, isolate duplicate X05, and hold X04 for missing approval. Its corrected row read “WFT-051-X04 | rule: amount, date, merchant, $75 cap, and documented approval rules | decision: match X01, flag X03 above the meal cap, isolate duplicate X05, and hold X04 for missing approval | static status: 10/10.” It changed only failed dimensions, adding support for Expense Reconciliation source traceability [WFT-051] and Expense Reconciliation handoff usability [WFT-051]. The final audit passed Expense Reconciliation task fidelity [WFT-051], Expense Reconciliation rule accuracy [WFT-051], Expense Reconciliation exception handling [WFT-051], Expense Reconciliation source traceability [WFT-051], and Expense Reconciliation handoff usability [WFT-051]. All five dimensions had inspectable support after one correction. The receipt-to-transaction reconciliation, policy exception register, and approval queue earned 10/10 from 5 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.",
