Three post-quantum KEMs now sit inside one of the principal international standards for asymmetric encryption: ML-KEM, Classic McEliece and FrodoKEM. Read that again. Not one algorithm. Three. From three different mathematical families. Why this matters before the detail. A standards body had a choice. It could have ratified the market's preferred answer, ML-KEM, and closed the question. It did not. It standardised a structured lattice scheme, an unstructured lattice scheme a
