Proof health & closures by source

Proof health · median disproof number on the AND frontier: 73 over 206 open obligations, of which 37 (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 10.5h (median of 136) · measured at 2026-10-03 02:00 UTC

Closures by source, last 24h (345575 of 345575 labelled): USER 99.7% (344557) · FILL 0.0% (0) · AUTO 0.0% (0) · SOLVE 0.0% (0) · NONE 0.3% (1018) · last 7d (2711991 of 2711991): USER 98.5% (2672289) · FILL 0.3% (8452) · AUTO 1.0% (26873) · SOLVE 0.0% (0) · NONE 0.2% (4377). Labelling started at deploy: closures older than that carry no source and are counted in none of the shares above.
