# Pattern Doc Entity
### Scope
- **Purpose**: Document reusable structural patterns for common api_gemini usage scenarios.
- **Responsibility**: Master file listing all pattern instances with ID, name, and pattern scope.
- **In Scope**: Architectural patterns addressing distinct failure modes or operational constraints — each pattern covers one problem/solution/applicability context.
- **Out of Scope**: Step-by-step API call procedures (see `operation/002_usage_examples.md`), enterprise feature configuration (see `feature/002_enterprise_reliability.md`), protocol wire format (see `protocol/`).
