Proof health · median disproof number on the AND frontier: 71 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 44.4d (median of 46) · measured at 2026-11-01 09:00 UTC
Closures by source, last 24h (128973 of 128973 labelled): USER 99.8% (128707) · FILL 0.2% (231) · AUTO 0.0% (0) · SOLVE 0.0% (0) · NONE 0.0% (35) · last 7d (1258446 of 1258446): USER 97.9% (1232206) · FILL 0.8% (9572) · AUTO 1.3% (16193) · SOLVE 0.0% (0) · NONE 0.0% (475). Labelling started at deploy: closures older than that carry no source and are counted in none of the shares above.
