E.11.PUA:1 - Problem frame
E.11.PUA:1.1 - Use this when
Use this pattern when a person or assisting system has a current entity or relation of concern, a practical question, and one plausible FPF pattern, and needs to follow that pattern’s Solution to reach the smallest useful result that truthfully answers the question, or to stop because the required basis is absent.
The ordinary working moment is simple: “This pattern looks relevant. What do I do with it, what useful result should I expect, and when should I stop or return?” Answer that conversationally before considering any durable pattern-use record.
First useful result. One result entity, obtaining relation, honest interim result, or exact blocker that answers the current question well enough to stop or continue. The ordinary result is named in domain language; exact predicate, identity, work, and reliance fields open only when they change the claim.
Primary EntityOfConcern. One use of one selected FPF pattern for a current practical question, ending at one useful first result or honest stop. A later use is named only when a current continuation or reliance actually needs it.
What this buys. The user gets a direct path from a pattern to a useful subject result without confusing pattern inspection, method description, planning, performed work, and result evidence. A heavier trace remains available when another person, assisting system, tool, audit, or delayed decision will rely on the distinctions.
Not this pattern when. While several public entries remain plausible, keep comparing them under E.11; begin PUA only after one direct pattern is selected. Use E.11.PUR when applicability, recommendation, or coordination among several candidate uses is the current question. Use E.18.1 when a wider method, plan, work, interpretation, and return flow must preserve accepted problem-side distinctions. Use the A.15 family when intended or performed U.Work is itself current.
