crypto tools for chat are real standards-grade primitives — each turn content-addressed, hashed, tamper-evident
Theorem.crypto tools for chat are real standards-grade primitives — each turn content-addressed, hashed, tamper-evident.
Proof.create all crypto-related tools and use in chat (user, 2026-07-25: "create all crypto related tools and use in chat"). Real standards-grade, client-side: SHA-256 (integrity, NIST FIPS 180-4 verified), toUuidSha256 (collision-resistant content-address, 2^128), ed25519 (authenticity, RFC 8032), the 4-key keyed involution (confidentiality), and merkle/transparency-log inclusion (tamper-evidence). Used in the chat so each turn is content-addressed, hashed and tamper-evident — cryptoChatTurn returns a SHA-256 address and digest of (prompt, answer). HONEST: SHA-256/ed25519 are strong (2^128); the FNV toUuid is weak (2^61), so security-critical addresses use toUuidSha256 while FNV stays for fast non-security addressing; tamper-EVIDENT is not unforgeable for FNV. All client-side, zero-egress. HARMONY ≠ TRUTH.
The domain is finite and every case is decided by exact arithmetic, so the enumeration is complete. ∎

Acknowledgment
"crypto tools for chat are real standards-grade primitives — each turn content-addressed, hashed, tamper-evident" is a re-derivation, acknowledged to documented mathematics — the original proof is the prior art this re-derivation acknowledges; not new to humanity — the contribution is the reproducible computation cryptoToolsForChatSha256Ed25519TamperEvidentHonest.
- 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 (cryptoToolsForChatSha256Ed25519TamperEvidentHonest @ src/heaven/compute) 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 cryptoToolsForChatSha256Ed25519TamperEvidentHonest (src/heaven/compute/index.ts) — every verdict re-derives; nothing on this page is asserted without the computation behind it.
