Proof health · median disproof number on the AND frontier: 71 over 200 open obligations, of which 36 (18.0%) 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 41.3d (median of 91) · measured at 2026-10-30 02:00 UTC
Closures by source, last 24h (191005 of 191005 labelled): USER 96.8% (184942) · FILL 2.2% (4167) · AUTO 1.0% (1824) · SOLVE 0.0% (0) · NONE 0.0% (72) · last 7d (1649928 of 1649928): USER 98.4% (1623487) · FILL 0.6% (9638) · AUTO 1.0% (16257) · SOLVE 0.0% (0) · NONE 0.0% (546). Labelling started at deploy: closures older than that carry no source and are counted in none of the shares above.
