OPS.6:4.6 - Admit performance and update state separately

After the Work, recover direct performance evidence, the changed subject or result, failures and limits, and the claim each observation supports. Update the case-state claim only when the relevant Work and resulting evidence are independently adequate. If Work did not occur or evidence is insufficient, retain the earlier state claim under its stated limits and return the unmet condition. Never use a record update, successful invocation, generated artifact, or selected action as automatic progression evidence.
