Proof health · median disproof number on the AND frontier: 72 over 198 open obligations, of which 37 (18.7%) 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 54.7m (median of 96) · measured at 2026-11-02 01:00 UTC
Closures by source, last 24h (216014 of 216014 labelled): USER 98.0% (211763) · FILL 1.5% (3304) · AUTO 0.4% (890) · SOLVE 0.0% (0) · NONE 0.0% (57) · last 7d (1284825 of 1284825): USER 97.9% (1257346) · FILL 0.9% (10933) · AUTO 1.3% (16075) · SOLVE 0.0% (0) · NONE 0.0% (471). Labelling started at deploy: closures older than that carry no source and are counted in none of the shares above.
