Module dilithium 

Dilithium / ML-DSA Post-Quantum Signature Verification

Implements FIPS 204 (ML-DSA) structural verification for Dilithium3 (security level 3). Full NTT polynomial arithmetic is deferred to Phase 7.5; the current implementation performs structural validation and hash-based binding verification.
