# Algorithm Doc Entity
### Scope
- **Purpose**: Document algorithms used in the claude_version implementation.
- **Responsibility**: Index of algorithm doc instances covering settings type inference and config resolution.
- **In Scope**: value:: type inference rules, precedence order, edge cases; 4-layer config resolution algorithm.
- **Out of Scope**: Settings JSON I/O design (→ `feature/003_settings_management.md`), CLI parsing (→ `feature/005_cli_design.md`).
