Proof health · median disproof number on the AND frontier: 70 over 207 open obligations, of which 38 (18.4%) 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 2.6m (median of 175) · measured at 2026-10-18 15:00 UTC
Closures by source, last 24h (156580 of 156580 labelled): USER 97.6% (152747) · FILL 0.4% (572) · AUTO 2.0% (3199) · SOLVE 0.0% (0) · NONE 0.0% (62) · last 7d (746769 of 746769): USER 90.1% (672644) · FILL 0.9% (6850) · AUTO 8.9% (66745) · 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.
