Post-Quantum Signatures: Fiat-Shamir Lattices versus Hash Trees

NIST standardized two very different signature philosophies. Comparing ML-DSA and SLH-DSA side by side, plus the stateful hash-based schemes, reveals the real trade-space: assumptions, size, speed, and the one operational rule that must never break. Grounded in FIPS 204, FIPS 205, SP 800-208, and the RFCs.
