The 7-layer Cooley-Tukey NTT, BaseMul,\nIndCPA, and FO transform are all proved end-to-end with no escape hatches.\n\nAll three FIPS 203 parameter sets -- ML-KEM-512, ML-KEM-768, ML-KEM-1024\n-- are supported and selected at build time via the `parameter_set`\ncrate configuration variable; default is ML-KEM-768 (NIST Category III).\n\nProof techniques are documented in PROOF_NOTES.md and reusable for similar\nlattice / ARX cryptography.\n\nBuilt on sha3_ada for SHA-3/SHAKE. No heap allocation, pragma Pure, suitable\nfor embedded and safety-critical systems. Constant-time execution\nempirically verified via cachegrind (LLd byte-identical). FIPS 140-3\nvalidation is out of scope. See SECURITY.md for the full threat model.\n",
