Be proactive: apply principles broadly

A rule is usually stated on one example, but the problem it names rarely lives in one place. So a rule or a finding is applied to everything it plausibly covers, not only to the case that prompted it.

The user, 2026-09-27: “be proactive and apply anything else related to this not mentioned here. apply principles broadly”.

• A rule or finding covers everything it plausibly applies to, not only the case it was stated on.
• It works with UR-19 (every rule applies to all existing code) and UR-18 (the class, not the instance, gets the guard).

How it is enforced: by review. It is a working rule with no mechanical guard of its own; the breadth it asks for is enforced where a guard’s scope is checked (UR-20).
