Proof health · median disproof number on the AND frontier: 70 over 207 open obligations, of which 39 (18.8%) 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 46s (median of 109) · measured at 2026-10-22 04:00 UTC

Closures by source, last 24h (998885 of 998885 labelled): USER 99.6% (994891) · FILL 0.1% (744) · AUTO 0.3% (3202) · SOLVE 0.0% (0) · NONE 0.0% (48) · last 7d (2633334 of 2633443): USER 97.2% (2559145) · FILL 0.4% (10585) · AUTO 2.3% (60736) · SOLVE 0.0% (0) · NONE 0.1% (2868). Labelling started at deploy: closures older than that carry no source and are counted in none of the shares above.
