Cleartext is a techno-thriller built on a machine nobody has publicly demonstrated. Most of the cryptography around that machine is taken directly from published standards and papers: RFC 8017, FIPS 203, Signal's PQXDH announcement, the NIST post-quantum FAQ, Executive Order 12333. This essay traces seven such details to their primary sources, then states plainly which parts of the book are invented, and how far real quantum hardware sits from the fictional machine.
