#![cfg_attr(coverage_nightly, coverage(off))]
//! Category A: Falsifiability & Testability (25 points) - GATEWAY
//!
//! The cornerstone of Popperian science: claims must be testable and potentially refutable.
//!
//! ## Sub-categories
//!
//! | ID | Name | Points | Description |
//! |----|------|--------|-------------|
//! | A1 | Hypothesis Documentation | 8 | Clear falsifiable claims documented |
//! | A2 | Test Coverage as Falsification | 10 | Tests attempt to refute claims |
//! | A3 | Benchmark Reproducibility | 7 | Performance claims with confidence intervals |
//!
//! ## Gateway Logic (v1.1)
//!
//! If Category A scores below 15/25 (60%), the total score is 0.
//! This implements Popper's demarcation criterion.
//!
//! ## Academic Foundation
//!
//! - Popper, K. (1934): The Logic of Scientific Discovery [1]
//! - Jia, Y. & Harman, M. (2011): Mutation Testing Survey [4]
