//!
//! **Specification**: docs/specifications/ruchy-sqlite-testing-v2.md Section 1.1
//! **Research Foundation**: NASA MC/DC (DO-178B/C), `SQLite` Lemon parser methodology
//! **Ticket**: SQLITE-TEST-001
//! **Status**: 100% Milestone ✅ - 20,000 property iterations (145/2000 tests = 7.25%)
//!
//! # Coverage Goals
//!
//! - 100% grammar production rule coverage
//! - 100% MC/DC (Modified Condition/Decision Coverage) on boolean logic
//! - Exhaustive operator precedence validation
//! - Complete error recovery path testing
//! - Property tests: parse-print-parse identity
//! - 20K property test iterations (10x baseline, 100% TARGET ACHIEVED ✅)
//!
//! # Test Organization
//!
//! - **Category 1**: Expression Grammar (literals, operators, patterns)
//! - **Category 2**: Error Recovery (malformed input, graceful degradation)
//! - **Category 3**: Performance & Complexity (O(n) parsing, linear memory)
//! - **Category 4**: Property-Based Fuzzing (invariant validation)
//!
//! # Target Test Count: 2000+
