A bare quote-post: the poster reproduces one sentence from Coinkite, "The hacker could have done the right thing and responsibly disclosed", attributes it to Coldcard and adds nothing else. The rendered capture shows the quoted item, the vendor reply registered here as coldcardwallet-2085551118164132316, which is the whole substance of the post; the text on its own does not carry it. Held as the first captured instance of that sentence being lifted out and circulated as a rebuke rather than read as a statement, roughly two hours after the vendor posted it. The post makes no factual claim of its own beyond the quotation, and the criticism it implies is the poster's.

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