The Claims Ledger

Every significant claim PTJ relies on, with its status, confidence, source, and last-checked date — including the ones we haven't resolved and the ones we got wrong. Most publications keep this file internal. We think publishing it is the point.

Status key: Verified (primary) — read in an official/primary document · Verified (reported) — credible dated reporting · Company claim — a company's own statement, dated · Unresolved — we don't know yet and say so · Stale — old enough to distrust until reconfirmed · Resolved — was disputed, now settled, shown with the answer.

18 published claims. The table scrolls horizontally on narrow displays and stacks into cards on small screens.

What you're seeing: the ledger includes claims we can't verify yet (CL-007), claims that went stale (CL-018), and a dispute we resolved by buying the standard (CL-009). Entries carrying company claims are labeled as claims. When an entry changes, the change is dated. The full internal ledger runs to 51 entries; items appear here once they support something we publish.
