Zach Herbert argues that Coinkite cofounder DocHex (Peter Gray) is the same person as the nym switck who contributed the libngu code change at the center of the Coldcard RNG bug, citing a shared phone-number ending on Peter Gray's Clarity.fm profile and both X accounts, plus James O'Beirne's finding that DocHex's GPG key signed 61 switck commits. Held as a dated primary claim and independently checkable lead about the provenance of the affected code. The inference is the poster's own and the archive has not independently verified the phone-number match or the GPG signature count.
