CAUSAL-USE — Keep a causal-looking result within its support

• Situation: A correlation, estimate, simulation, or comparison is being used to say that an action will cause an outcome.
• Question: What causal statement may the evidence support, and what stronger statement must not guide intervention or investigation?
• First useful result or blocker: A supported statement and its limit, or the missing alternative, intervention, comparator, evidence path, identification result, or transport basis.
• Start with: C.28.
• Stop or return: Stop, narrow the claim, or abstain when support is insufficient. The causal-use result does not choose, deploy, publish, or certify by itself.
