E.18.1:1.3 - What this buys

The practitioner gets one concrete next move: keep the accepted claim in view, state the question and participants, apply the pattern that answers it, and use the result it returns. Split several relation claims before applying their patterns. If the relation or needed facts are missing, keep the cue and stop. If a relied-on result changes, reopen only the continuation that used it. Add the compact note only when another person or later action must replay that path. The accepted problem-side distinction remains useful without becoming hidden permission to start work.
