Tao posted 'Palomar: A registry of Lean verified mathematics' on 2026-08-18, which reached 181 points and 39 comments on HN. The blog post itself returned 403 to automated fetching so the registry's entry count and contribution model are not confirmed here, but the pairing with his ICM essay arXiv 2608.16753 the same week is the readable signal: the same person arguing about what mathematics is for is simultaneously building machine-checkable infrastructure for it. Treat the specifics as unverified until the post is read directly.
