Overview

EV-z7f5 / GH #1325: unresolved mutations are excluded from ‘score_denominator`, so a run whose specs could not be auto-resolved collapses to a bare “Score: 0.00% (0/0)” that reads like a genuine mutation-quality failure. This formatter surfaces a loud, actionable warning when the unresolved rate is high — and a distinct message when the denominator hit zero (nothing was measured at all) — so the user knows to pass –spec instead of trusting the 0.0.

Sibling of ErrorRateWarning (EV-nrgw / GH #1168).
