PSD.10:4.3 - Qualify the relied-on claims

For each decision-bearing source result, keep the claim, subject, supplying result kind, source edition or effective window, assumptions, evidence, intended use, exclusions, and material dissent recoverable. Use A.10 for the actual bounded reliance question; its disposition does not establish the source claim’s truth or authorize the decision.

Ask whether the evidence concerns the same holder, intervention, environment, and horizon. Separate observed results, forecasts, expert judgements, and unsupported extrapolations. An observation of a benefit is not automatically a causal effect; the direct causal or domain Method supplies that support.

Use an already-qualified result within its limit. If a consequential cross-practice result is still missing, A.15.9 supports the smallest request or blocker. Do not ask another practice to “remove the uncertainty”; ask for the specific claim, bound, interpretation, or test that could change this comparison.
