E.9.DA:1 - Problem frame
Use E.9.DA when one exact DRR must be checked for decision adequacy under a declared FPF authoring use: pattern drafting, host amendment, selected-locus distribution, accepted-decision carry-through, source-use carry-through, scope-boundary decision, split decision, or architecture-hold decision. Add exact C.2.1 episteme identity only when the judgement or a named later reliance depends on it. E.9.DA supplies the object-specific evaluation questions and reusable coordinate meanings.
Use E.21 to judge an authored pattern version, E.19 to review an FPF pattern edition or bounded subset for admission or refresh, F.19 for ordinary wording repair with E.10 as cue and unresolved-meaning route, and C.16, A.17, A.18, and A.19 for measurement-law questions. Those questions are outside this DRR-adequacy evaluation.
First useful move: read the exact DRR in its declared authoring use and state its working problem, selected answer, practical change, first drafting action, and boundary. When it selects a broad authoring rule, inspect the actual predecessor/proposed host effect before opening any optional assessment or result apparatus.
What goes wrong if missed: a formally valid DRR may still be too weak for drafting. It may summarize sources instead of deciding, mention neighbours without obligations, hide rejected alternatives, leave trigger words unresolved, or omit the first drafting action.
Primary EntityOfConcern in plain terms: one exact DRR checked for one declared FPF authoring use and qualification window. Assessment work, a reusable coordinate result, witnesses, records, status use, assurance, acceptance, and later repair are separate only when those objects are actually current.
