# Feature Doc Entity
### Scope
- **Purpose**: Document the user-facing capabilities provided by the `component_model` crate.
- **Responsibility**: Collect one navigational hub per capability; each instance cross-references all relevant source, test, and documentation artifacts across the three-crate ecosystem.
- **In Scope**: Implemented, committed features accessible through this crate's public API.
- **Out of Scope**: Internal implementation details in absorbed crates (→ their own `docs/`); architectural design decisions (→ `pattern/`).
