# Algorithm Doc Entity

### Scope

- **Purpose**: Document internal algorithmic design for maintainers and performance-conscious contributors.
- **Responsibility**: Index of algorithm doc instances; each instance explains the approach, selection criteria, and performance characteristics of one internal algorithm.
- **In Scope**: SIMD delimiter search, single-char split specialization, Boyer-Moore-inspired split for multi-char single-delimiter patterns.
- **Out of Scope**: Public API contracts (`api/`); user-facing feature descriptions (`feature/`); correctness guarantees (`invariant/`).

### Overview Table
