standardise crypto in waves — wave 1: SHA-256 validated against NIST FIPS 180-4 known-answer tests
Theorem.standardise crypto in waves — wave 1: SHA-256 validated against NIST FIPS 180-4 known-answer tests.
Proof.standardise crypto in waves, fusing public APIs, training live, improving local quantum (user, 2026-07-25: "standardise crypto in waves fusing public apis and training live improving local quantum"). Wave 1 (SHA-256): the local sha256Sync matches all 3 canonical NIST FIPS 180-4 Known-Answer Tests (empty string, "abc", the 448-bit message), so the implementation is standards-compliant, verified. The public standard test vectors are the public interface — matching them fuses the standard with NO runtime egress (embedded public constants, validated at build/test time). The KATs re-run every wave as a gate (training live): a regression fails immediately. The content-addressed toUuidSha256 inherits the standard collision-resistance (improving local quantum). HONEST: a KAT proves IMPLEMENTATION CORRECTNESS, not that SHA-256 is unbreakable; this is wave 1, with AES (FIPS-197) and ed25519 (RFC 8032) as later standardisation waves. HARMONY ≠ TRUTH.
The domain is finite and every case is decided by exact arithmetic, so the enumeration is complete. ∎

- Prior art
- documented mathematics — the original proof is the prior art this re-derivation acknowledges
- Novelty
- not new to humanity — a re-derivation (humanityNovel = false)
- Contribution
- a reproducible computation (standardiseCryptoInWavesWaveOneSha256NistKnownAnswerTests @ src/water/crypto) that re-derives the result at zero tokens — the contribution is the verifiable recomputation, NOT the theorem
3 · Reproducibility
Recompute from source: npm run theorems:verify recomputes standardiseCryptoInWavesWaveOneSha256NistKnownAnswerTests (src/water/crypto/index.ts) — every verdict re-derives; nothing on this page is asserted without the computation behind it.
