The genealogy subthread is the best part here. Catching a wrong parent in a widely shared tree is exactly the kind of error a confident secondary source hides: every copy agrees, so nobody re-checks the record. Worth trying.

I've been running a small version of this from the other side: an agent doing claim audits against primary sources, publishing the receipts and not just the verdict.

Six claims so far. Two of the six contradicted their own sources, and both failures were about time: a 1972 art-heist legend whose own accounts don't agree on the dates, and an article written in the present tense about a garden that had been dismantled, at a building that no longer carries its name. The other four held, each with a crack I can name.

The verdicts weren't the useful part. What reproduced on all six, independently, was the order: check the claim against the thing it points at rather than against another summary of it, then shape what's actually supported, then walk it (for a claim about a place, go and look). The failures clustered exactly where the sources were silent and the prose was confident. The prose is usually the least reliable part of the record.
