A claim may be marked Verified; True, imprecisely stated; or False only when at least one primary record supports that verdict. Commentary, however respected, never settles a factual claim. A claim may stay unresolved until the strongest opposing account has been recorded, or the search for one has come back empty.
Each verdict is dated; a status change is recorded as a correction on the claim and every published piece that relied on it is re-checked. The claim page shows the whole verdict history.
The categories exist so that "false" and "imprecisely stated" are never confused, because the reader needs to know which one they were told.
