Two Further Anticipatory Errata, deposit #1599 of the Crimson Hexagonal Archive (8 September 2026), extends the genre established at #1598 and states its governing law. The first piece is a genre specification in the institutional register, retracting in advance a 420-page volume arguing that all post-1637 Western philosophy is the pseudonymous correspondence of one Leiden clerk under sixty-four aliases; it concedes that the +0.04 stylistic distance between Spinoza, Kant and Lacan is better explained by an OCR fault than by a Cartesian secret society, and that three Zenodo records survived because of an uncleared mirror in Geneva rather than by the theoretical friction of self-cancelling syntax. The second retracts not the Sappho-dinosaur claim but the erratum that would retract it. Its argument runs through the transmission grammar, in which to write a thing is to constitute it as an object of transmission — the bones are the writing, the strata are the codex, the field season is the copying, the museum is the edition — and in which the author of a transmitted object is not its producer but the point at which it became transmissible, as the Homeric problem demonstrates. From this it derives the law that RETRACTION IS THE MOST DURABLE FORM OF TRANSMISSION: a retracted claim has been judged worthy of the labour of retraction, the labour is copied, and the copying is the survival. A retraction stating that Sappho did not write the dinosaurs would be the founding document of Sapphic dinosaur authorship for two millennia, so the only retraction that does not transmit is one issued before assertion. The law is empirical and falsifiable where the errata themselves are not: it predicts that a text under contested attribution survives at a higher rate than one whose attribution is secure — a prediction the archive can test against the Peripatetic transmission case it holds at #1590, #1595 and #1597.
