A grade belongs to what was actually observed, not automatically to every page, hostname or authenticated area that the business operates.","Read the underlying findings before discussing a target score. Two tools can use different criteria, and a tool can change over time. The old archived Mozilla Observatory scoring table is not a current specification for every scanner.

Treat that as a documented boundary of the tool, not evidence that those excluded problems exist on a specific website.","A public response review cannot establish private account roles, the integrity of a backup or what an application does with customer information.

For header work, review required resources and integrations before enforcement. A stricter policy can improve a test result while preventing a legitimate form or payment flow. A public score cannot choose that business tradeoff on behalf of the owner.","Use a controlled environment or authorized limited rollout when appropriate. Record the before observation, intended behavior and acceptance criteria.

Then verify normal business behavior using approved test data and provider-supported procedures. A test form should reach the expected destination; an approved login should work; a test checkout should follow the agreed test process. Do not accept the change from a screenshot of the new grade alone.","Separate what was directly observed from what a supplier documented or what remains untested. If a public service records scan results, review its publication and privacy behavior before submitting sensitive targets. This guide does not require an external scan to understand a finding; an authorized configuration review and local evidence can establish a narrower question without exposing private routes.",{"title":81,"text":82},"Illustrative high-grade availability failure","A restrictive content policy improves the tested grade, but the authorized form test stops before delivery.
