ME.20:10 - Architectural Rationale

General pattern use and live Work steering already exist. The Method Engineering contribution is the connection between a current professional question, the distinct result that can answer it, and the smallest affected return when that result’s basis changes. The table in §4.1 and the two-turn case make that connection usable without copying the full qualification, composition, representation, or steering Methods.

A direct MethodDescription is preferable when it already supplies the action and stop. A fixed route is useful when its dependencies remain sufficient. For a changing plurality of questions, reconstructing the returns from separate patterns can hide an unresolved whole or repeat unaffected qualification. This method keeps those returns visible at a cost proportionate to the present decision.

Pattern-language form supplies problem-oriented knowledge, not a replacement chooser. Local first–then dependencies can still matter. Neither situational use nor the word unfolding claims that Methods have no causal assumptions or that all actions can occur in any order.
