Policy-Based Authorization

A controlled Policy-Based Authorization pattern for maintainable systems.

Use Policy-Based Authorization when it directly addresses system complexity; do not introduce it without a concrete design need.

When to use it

Apply where the pattern creates an explicit boundary, invariant or operational benefit.

Improves clarity and makes responsibilities testable.

Adds abstraction and must remain proportionate to the system.
