Proof health & closures by source

Proof health · median disproof number on the AND frontier: 70 over 216 open obligations, of which 41 (19.0%) 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 8.2m (median of 13) · measured at 2026-10-13 23:00 UTC

Closures by source, last 24h (117680 of 117680 labelled): USER 99.4% (117014) · FILL 0.5% (553) · AUTO 0.0% (16) · SOLVE 0.0% (0) · NONE 0.1% (97) · last 7d (1336961 of 1336961): USER 97.5% (1303967) · FILL 0.2% (3075) · AUTO 2.2% (29472) · SOLVE 0.0% (0) · NONE 0.0% (447). Labelling started at deploy: closures older than that carry no source and are counted in none of the shares above.
