OPS.5:4.4 - Choose only where a real choice exists
When a direct domain rule, mandatory condition, or recognition branch gives the answer, apply it and record the basis. When several live admissible alternatives genuinely require comparison, form a stable current OptionSet and comparison basis and use C.11. If the options or comparison facts are insufficient, choose a bounded probe only when it can change the decision, or return the missing condition. Do not manufacture an OptionSet merely to make admission look analytical.
