Proof health · median disproof number on the AND frontier: 72 over 198 open obligations, of which 35 (17.7%) sit at or below dn 2, one unanswered question from falling over · 0 open nodes on impossible numbers · positions a visitor asked for close in 30s (median of 164) · measured at 2026-11-02 20:00 UTC
Closures by source, last 24h (355805 of 355814 labelled): USER 99.8% (355095) · FILL 0.1% (352) · AUTO 0.1% (231) · SOLVE 0.0% (0) · NONE 0.0% (127) · last 7d (1437730 of 1437737): USER 98.5% (1416208) · FILL 0.7% (9526) · AUTO 0.8% (11424) · SOLVE 0.0% (0) · NONE 0.0% (572). Labelling started at deploy: closures older than that carry no source and are counted in none of the shares above.
