MNT.2:10 - Architectural Rationale
A reusable policy differs from a current intervention choice: one establishes when a task generally applies, while the other resolves a present case. Keeping them related but separate permits a valid policy to coexist with an exceptional current response.
The task alternatives remain plural because failure visibility, mechanism, consequence and support differ. A single escalating technology sequence would discard legitimate corrective and failure-finding policies.
