Proof health & closures by source
Proof health · median disproof number on the AND frontier: 69 over 195 open obligations, of which 36 (18.5%) 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 9.1m (median of 3) · measured at 2026-11-03 10:00 UTC
Closures by source, last 24h (708407 of 708440 labelled): USER 100.0% (708221) · FILL 0.0% (0) · AUTO 0.0% (0) · SOLVE 0.0% (0) · NONE 0.0% (186) · last 7d (1838177 of 1838375): USER 99.1% (1822412) · FILL 0.5% (8983) · AUTO 0.3% (6132) · SOLVE 0.0% (0) · NONE 0.0% (650). Labelling started at deploy: closures older than that carry no source and are counted in none of the shares above.
