The 22-case TokenType mapping was split across three initializers to stay under the complexity lint, leaving a preconditionFailure default the types could not prove unreachable, which also tripped the forbidden-patterns gate on every push. One exhaustive switch makes a new TokenType case a compile error instead of a runtime trap; the lint now ignores case statements when counting complexity, since exhaustive closed-enum switches are the point, not a smell.
