# Codebase Deepening Audit

Survey a codebase to identify architectural improvement opportunities based on John Ousterhout's "deep modules" philosophy (lots of behavior hidden behind a simple interface).

## Core Concepts
- **Deep Modules**: Modules that provide extensive functionality while exposing a simple, clean interface.
- **Surface Complexity**: Eliminating superficial abstractions or excessive small classes/files that increase cognitive load without adding value.
- **Visual Reporting**: Generating actionable HTML reports detailing structural candidates for refactoring.

## Workflow
1. Scan the repository structure and module boundaries.
2. Evaluate interface-to-implementation ratios across components.
3. Generate a structured report highlighting deepening opportunities and architectural risks.

## Quando Ativar

- Usuário pede auditoria de arquitetura ou "improve codebase architecture"
- Identificar módulos rasos que devem ser combinados ou aprofundados
- Usuário diz "deepening modules", "auditoria de arquitetura", "módulos profundos", "arquitetura limpa"
- Antes de refatoração estrutural grande no repositório

## Exemplo

```bash
# auditar fronteiras de módulos e gerar relatório HTML
audit-deepening --scan ./src --report ./reports/deepening.html
```
