Bryan Jacoutot's argument that blaming poor user dice rolls cannot account for a pre-existing transaction at a derived address, because that requires a second party to have independently arrived at the same key, whereas a defective firmware RNG shared across devices does explain it. A clean statement of why the user-error explanation fails on the collision evidence. The reasoning is stated and can be argued on its merits; the archive has not re-derived it from a specific transaction.

This post is registered as evidence and has a locally held capture. The original remains the canonical publication.
