E.11.PUR:5.1 - Applicable but not recommended

A team considering a high-cost pump test has candidate uses of C.28 causal triage and A.21 gate discipline. Both may be applicable. The immediate uncertainty is whether a causal model output may support intervention, so C.28 offers the more useful first result. That uncertainty and the recommendation are epistemic; neither asserts an actual C.22.PFR Problem.

Recommend C.28 without claiming that the test is authorized. The later gate use remains a separate candidate whose applicability can be reconsidered after the causal-use result exists.

Because this local recommendation is reversible and no named later use relies on it, the team states the applicability result and one compact rationale over all five aspects in the working conversation; it materializes no recommendation episteme or support profile. If a later gate review needs to replay each aspect independently, that review may create current fit findings and a current applicability finding from the then-current basis. It does not backdate those addressable findings; if the original readable rationale was retained, it remains the earlier recommendation’s historical basis.
