Check
The same fact does not differ between pages
The same fact does not differ between pages is check C2 in the fifteen-point audit. Facts that appear on more than one page agree: prices, dates, versions, names.
What counts as evidence
The conflicting values we found and the pages they appear on.
How to fix it
Keep shared facts in one place (a component, a setting) instead of copy-pasting them into templates.
Where this sits
C is the group: accessibility, comprehension, or extractability. The groups run in order — a crawler that cannot reach the page never reaches the reading checks — so fix the earliest failing group first. The full definition of all fifteen items is in the standard.
