Proof health & closures by source

Proof health · median disproof number on the AND frontier: 81 over 197 open obligations, of which 32 (16.2%) 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 4.5h (median of 34) · measured at 2026-09-28 22:00 UTC

Closures by source, last 24h (247422 of 247422 labelled): USER 99.8% (246838) · FILL 0.0% (0) · AUTO 0.0% (0) · SOLVE 0.0% (0) · NONE 0.2% (584) · last 7d (1565665 of 1565684): USER 97.2% (1522485) · FILL 0.6% (8795) · AUTO 2.0% (32065) · SOLVE 0.0% (0) · NONE 0.1% (2320). Labelling started at deploy: closures older than that carry no source and are counted in none of the shares above.
