Proof health · median disproof number on the AND frontier: 72 over 199 open obligations, of which 37 (18.6%) 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 1.8m (median of 44) · measured at 2026-11-01 21:00 UTC
Closures by source, last 24h (202626 of 202626 labelled): USER 98.2% (198959) · FILL 1.5% (2952) · AUTO 0.3% (659) · SOLVE 0.0% (0) · NONE 0.0% (56) · last 7d (1291032 of 1291032): USER 97.7% (1261173) · FILL 1.0% (12524) · AUTO 1.3% (16852) · SOLVE 0.0% (0) · NONE 0.0% (483). Labelling started at deploy: closures older than that carry no source and are counted in none of the shares above.
