Overview

This class is part of a private API. You should avoid using this class if possible, as it may be removed or be changed in the future.

EV-nrgw / GH #1168: Score is killed / score_denominator where score_denominator = total - errors - neutral - equivalent - unresolved - unparseable — errors are excluded from the denominator entirely. A run can read PASS at 100% while 16 of 19 mutations silently errored. This formatter surfaces a warning right under the metrics block when the error rate crosses the threshold so the silent failure mode becomes loud.
