# Feature Doc Entity
### Scope
- **Purpose**: Navigational hubs for each implemented user-facing benchkit capability.
- **Responsibility**: Collects all source, test, and documentation artifacts for each feature in one place.
- **In Scope**: Implemented benchkit features with committed tasks; Design section covering modes and key decisions.
- **Out of Scope**: Implementation details and Rust-specific types (→ source code); NFR constraints (→ invariant/).
