All quoted material traced verbatim. The article's deliberate omission of the specific April 29 release date (per the agent's note: 'none of my three cited sources gave a verbatim date') is a precaution against fabrication and is the editorially correct choice.

APPROVE. Cryptography, sources, content, and quoting discipline all clean. Notable for the conservative omission of unverifiable details (release date).
