Proof health · median disproof number on the AND frontier: 72 over 197 open obligations, of which 35 (17.8%) 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 2.5m (median of 36) · measured at 2026-11-02 19:00 UTC
Closures by source, last 24h (347830 of 347830 labelled): USER 99.5% (345999) · FILL 0.3% (1163) · AUTO 0.2% (541) · SOLVE 0.0% (0) · NONE 0.0% (127) · last 7d (1424520 of 1424526): USER 98.4% (1401069) · FILL 0.7% (9950) · AUTO 0.9% (12927) · SOLVE 0.0% (0) · NONE 0.0% (574). Labelling started at deploy: closures older than that carry no source and are counted in none of the shares above.
