## 🤖 Automated Benchmark Workflow (CodeExplorer Benchmark Workflow)

1. **Ingestion & AST Construction:**
   * Clone repository with `--depth 1`.
   * Run the CodeExplorer parser (`index`): measure AST parsing throughput, peak RAM consumption, and error-free handling of advanced syntax.

2. **Cross-File Symbol Resolution:**
   * Verify link accuracy across types, interfaces, base classes, and implementations.
   * Test resilience against circular references, complex generics, and dynamic meta-types.

3. **Architecture Query Verification:**
   * Detect package/module dependency cycles.
   * Calculate coupling and cohesion metrics alongside inheritance tree depth.

4. **Automated Library Catalog Enrichment:**
   * Scans build files (`*.csproj`, `package.json`, `go.mod`, `pom.xml`/`build.gradle`, `pyproject.toml`/`requirements.txt`).
   * Automatically classifies new popular third-party dependencies and ingests them into CodeExplorer's knowledge graph.
