* hanzo-evm: aiquorum + aimarket precompiles, evmllm (geth AI precompile + e2e), operator/canonical (commit/reveal, int8-quant), aiffi bench. Thinking-chain substrate. * hanzo-evm/evm: wire AI precompiles (inference 0x0300..03 + modelregistry) Registers deterministic int8 inference (Tier-1 in-consensus AI) + ModelSpec registry into the Hanzo EVM. threshold dep aligned to v1.9.4 (go.mod match). Builds green (55M binary). aivmbridge follows luxfi/precompile release.

// The operator's on-chain identity is its EVM (secp256k1) address, so an
|
|
// attestation is a 65-byte secp256k1 signature [R(32) || S(32) || V(1)] over

// the digest. The precompile recovers the signer and checks it equals the
|
|
// operator recorded at meter time — no separate key registry, no trusting
|
|
// calldata for the signer. This is the canonical EVM identity proof.
|
|
//
|
|
// The digest is keccak256(recordId, resultHash); the operator signs it to

// attest "I produced resultHash for this request". Settlement is gated on

// this, not a second credit (funds were escrowed + credited at Meter).
