pub const REFEREED_DIFFERENCE: &str = "tessellated from the exact compiler's difference, operands within tolerance";Expand description
REFEREED_UNION for a difference whose mesh held a void the exact
result lacks, bounded by skins within rounding where the cutter met its
host, and which the exact compiler decided (#423, ADR 0098). A
difference with no extra shell, or whose faces the exact compiler read
further than rounding, is never refereed: a skin or void thinner than
the tolerance stays as authored (ADR 0096, D7).
