Continue leftover Hilbert 16(a) degree 8 after the q1 wrap (PR #83, merged as 6ae8676). Census lower bound still 2,384. Ranks 21–26 (20 census triangulations) were never in the q1 leftover. The two open (19,3) deep nests are still undecided. Store under compute/q2/. Covering stays frozen. Do not claim a new scheme unless independently replayed and outside the 2,367 plus the seventeen.
