# Algorithm Test Surface
### Scope
- **Purpose**: Test case specifications for claude_version algorithm doc instances.
- **Responsibility**: Per-algorithm test specs verifying algorithm steps and edge cases.
- **In Scope**: Algorithm test planning (AC- prefix, min 4 cases per spec).
- **Out of Scope**: Feature tests (-> `feature/`), CLI command tests (-> `cli/command/`).
