Preferred sources
Manufacturer support, release notes, standards bodies and reproducible in-house tests sit at the top of the hierarchy. Each source record includes the publisher, URL or test artifact, permitted use, reviewed span and date.
Community reports
Reddit, forums, videos and user submissions are useful for discovering new failures. They do not establish a general fix without corroboration and version detail.
Conflicts
When official pages conflict across regions or versions, Home Product Support narrows the applicability rather than blending the instructions. The record states the unresolved limitation.
Screenshots and rights
Screenshots are captured or licensed for the exact guide and stored with version and rights metadata. Text equivalents describe the control path so the answer does not depend on an image.
