A.15.7:10 - Rationale

This pattern supplies a reusable Method for a common working question: what should this deciding System do next during current Work, given current facts and the Method that still bounds the Work? Keeping that Method separate from the domain Method preserves two independently testable claims while allowing either co-enactment or an admitted composite.

The pattern begins before late-stage option comparison and ends before tool-call planning or performed-action recording. That placement keeps the first result small and makes explicit comparison, generation, planning, evidence, and assurance conditional rather than universal burdens.
