    Class ComponentWrapperInstantiationRule

    Detects direct new X() instantiation of wrapper or adapter classes (identified by name patterns, explicit class names, base class inheritance, or decorator presence) in Angular codebases.

    Direct instantiation of component-wrapper, DTO-wrapper, or adapter classes breaks the Dependency Inversion Principle: callers take responsibility for constructing the dependency rather than receiving it through Angular's DI.

    Detection scope:

    • Tier 1 (fast, name-based): classNamePatterns and explicitClassNames
    • Tier 2 (AST-based): baseClassNames and decoratorNames after import resolution

    Skipped:

    • .d.ts declaration files.
    • Classes in excludedClassNames (Angular framework Ref types by default).
    const rule = new ComponentWrapperInstantiationRule();
    const results = await rule.analyze(createContext(sourceFile, project));
    // results[0].metadata.className          -> 'SomeRef'
    // results[0].metadata.detectionTier      -> 1
    // results[0].metadata.detectionMechanism -> 'classNamePattern'
