Contract
- Linter.verify validates custom rule options against JSON schema, interpolates report message placeholders, and provides AST tokens and lexical scope through context.sourceCode
- Linter.verifyAndFix applies fix transformations iteratively while preserving non-autofixable suggestions and remaining diagnostics in result messages
- Linter.getSuppressedMessages retains diagnostic records for rule violations bypassed by inline disable directives
- Linter.verify throws a descriptor error when a custom rule reports a messageId omitted from its meta.messages declaration
