Proof health · median disproof number on the AND frontier: 70 over 208 open obligations, of which 38 (18.3%) 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 3.7m (median of 54) · measured at 2026-10-18 06:00 UTC
Closures by source, last 24h (68980 of 68992 labelled): USER 94.5% (65180) · FILL 0.8% (522) · AUTO 4.6% (3199) · SOLVE 0.0% (0) · NONE 0.1% (79) · last 7d (673278 of 673278): USER 87.3% (587608) · FILL 1.1% (7395) · AUTO 11.5% (77745) · SOLVE 0.0% (0) · NONE 0.1% (530). Labelling started at deploy: closures older than that carry no source and are counted in none of the shares above.
