#![cfg_attr(coverage_nightly, coverage(off))]
//! O(1) Hooks Cache Manager (PMAT-453)
//!
//! Implements the 3-level hash hierarchy for O(1) pre-commit hooks:
//! - Level 0: Git tree hash (repo-wide cache)
//! - Level 1: Per-gate hash (staged files by type)
//! - Level 2: Per-file hash (individual file results)
//!
//! Phase 2: Per-gate caching for partial cache hits
//! Phase 3: Parallel gate execution with rayon
//!
//! Spec: server/docs/specifications/pmat-hooks-v2-spec.md
