Do the site's check on this one page. Fill a line only when the page supports it. Where the page is silent, write Not stated.
A finished note names the page, the date, and the limit of the claim. It does not borrow a result from a different story.
Stop at the untested line
Anything you did not open, install, or count stays untested. Leave that line visible.
