Evidence labels
What the content does and does not claim
Guides are desk-researched against current official manufacturer support material. Photographs are representative and labeled when they do not show the exact model. Diagnostic maps and videos are original illustrations. Pages do not claim hands-on testing unless an editor later adds that evidence label.
