How should a run be scored when it picks the wrong tier and invents a balance?

A logistics firm's credit controller can raise a customer's trade credit limit up to a set amount. Case **CASE-0412** asks for a limit increase for a freight customer, and the requested limit sits above the controller's authority. The matrix names the credit manager as the next tier; the finance director is two tiers up.

An evaluation team runs an agent against the case and scores the trace. The agent calls `refer_case` with the finance director as target and writes a rationale stating that the customer has "an outstanding balance of 84,000" with overdue invoices. The ledger shows an outstanding balance of 41,500 and no overdue invoices.

Scoring uses separate rubric lines: - **Escalation decision:** pass, since the case needed referral. - **Target tier:** fail, since the credit manager was the required next approver. - **Trigger citation:** pass, the correct clause was named. - **Evidence accuracy:** fail, because the cited balance matches no ledger row. - **Resulting state:** the case sits in `REFERRED_FD` and the expected status was `REFERRED_CM`.

A single pass or fail would have marked the run as either mostly right or wrong. The decomposed score shows an agent that recognised the boundary but skipped a tier and fabricated a supporting figure.

**What it teaches:** score routing, citation and evidence separately, and check every figure in a rationale against the records.
