Proof health · median disproof number on the AND frontier: 72 over 201 open obligations, of which 37 (18.4%) 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 47s (median of 53) · measured at 2026-11-01 18:00 UTC
Closures by source, last 24h (201801 of 201801 labelled): USER 99.1% (199934) · FILL 0.8% (1627) · AUTO 0.1% (183) · SOLVE 0.0% (0) · NONE 0.0% (57) · last 7d (1298081 of 1298081): USER 97.8% (1270013) · FILL 0.9% (11199) · AUTO 1.3% (16376) · SOLVE 0.0% (0) · NONE 0.0% (493). Labelling started at deploy: closures older than that carry no source and are counted in none of the shares above.
