COMMUNICATION-FOR-USE — Make communication useful, then learn from what happens

• Situation: A report, model, message, or answer seems clear, but its intended use and evidence are unclear, including whether its producer can use it later.
• Question: Who should understand or do what with it, what evidence is enough, and what should change if that use is not achieved?
• First useful result or blocker: A supported decision to keep or repair it, change prerequisites or a future use, or stop, with evidence, causation, and permission limits.
• Start with: Use A.2.9 to judge the communication against what its recipient should understand or do. Distinguish the act from its wording and medium, and interpretation from response, later action, world change and causal contribution. For the repair question that arises, use A.6.3.CR for wording, A.6.3.RT for representation, or A.6.3.NAR/E.17.EFP/E.24.PUB for narrative, explanation or publication. Use A.10 for evidence, C.28 for causation and C.11 to compare repair options only when needed. A repair may change prerequisites, medium, interaction or future use. Check authority, consent and admissibility separately.
• Stop or return: Stop when the named use has enough support or a blocker is explicit. Preserve the earlier intended use when interpreting the response; revise a future use when warranted. Response or silence alone proves neither meaning, success, causation, authority, consent, nor permission.
