Defined in:

Overview

Condition-negation operator (Tier 2, OFF by default). Wraps an if/unless/ ternary condition in !( ... ) textually. Ruby ternaries parse as IfNode in Prism, so visit_if_node covers them too (R12). The standard validity re-parse downstream discards any wrap that fails to round-trip (R14).

Clean-room: from the spec's operator description, not the mutant gem.
