Proof health · median disproof number on the AND frontier: 70 over 216 open obligations, of which 41 (19.0%) 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 1.4m (median of 34) · measured at 2026-10-13 19:00 UTC
Closures by source, last 24h (97480 of 97480 labelled): USER 99.4% (96852) · FILL 0.6% (553) · AUTO 0.0% (16) · SOLVE 0.0% (0) · NONE 0.1% (59) · last 7d (1339471 of 1339471): USER 97.5% (1306368) · FILL 0.2% (3195) · AUTO 2.2% (29497) · SOLVE 0.0% (0) · NONE 0.0% (411). Labelling started at deploy: closures older than that carry no source and are counted in none of the shares above.
