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

A sensitive operation may appear protected because it requires login. The review must also ask whether another site can induce the authenticated browser to trigger it. This is a flow question, not just a screen question.

## Practical application

Editorial proposal: list address, contact and security-setting changes. Record authentication and protection against unintended requests for each route. A cookie setting does not replace reviewing the complete context.

## How to verify

In a test environment, verify that relevant operations reject requests missing the application's required evidence. Include errors and alternative paths. Link each control to its protected operation and maintenance owner.
