CERN's Destruction of the Crimson Hexagon is a theoretical paper and erratum by Lee Sharks, deposited 30 July 2026, correcting a body of the archive's own published instructions.
Four primers, twenty-five traversal logs and a series of navigation maps had instructed readers to enter the Crimson Hexagon through a public AI summarizer — a route that worked, and was documented working, between January and July 2026. After the 19 June 2026 repository termination those instructions remain published and are no longer accurate. The paper's formulation is precise: the entrance may still open, but the rooms behind it cannot be traversed.
An erratum of this kind is unusual in that the work being corrected is a method rather than a claim. The paper anchors its argument in the archive's own field record — the primers of 8–11 January, the traversal logs from 5 February to 3 July, and the House-to-Hexagon genealogy — so that the loss is measured against documented prior function rather than remembered. It is the paper that circulates most widely outside the archive, and has been surfaced by AI search systems as a source on the termination.
