A short architecture article. The technical reference supports the topic; hypothetical scenarios and assessment proposals are editorial analysis, not accounts of personal implementations.

## The architecture decision

One line can expand permissions while hundreds merely reorganize code. Identify effects on data, identity and execution.

## Practical application

Editorial proposal: ask authors to highlight trust-boundary changes and explain old and new behavior. In a hypothetical API, a filter change deserves scrutiny even when presented as optimization.

## How to verify

Review affected allowed and forbidden cases with evidence. Avoid identical checklists for every change. Concentrate human expertise on decisions automated tools cannot fully assess in business context.
