KineticAttestor

KineticAttestor is a validator. It does not decide whether a motor moved. It decides whether the device key bound to an agent signed a specific record, recently, with a fresh nonce, and whether the agent’s owner has approved this contract to open a validation. Address: 0x6e46d149b7d3396b42E874765Cf5a1bb26BD5bA5. The proof format and the trust boundary are in Attestations. EIP-712 domain: KineticAttestor version 1.

ActionProof(uint256 agentId, bytes32 action, bytes32 paramsHash, string requestURI, uint256 timestamp, uint256 nonce)

Constant	Value
`MAX_PROOF_AGE`	10 minutes
`MAX_FUTURE_SKEW`	2 minutes
`VERIFIED_RESPONSE`	100
`ACTION_TAG`	`kinetic-action`

attest

function attest(ActionProof calldata proof, bytes calldata signature) external

Anyone may relay a proof. The device relays its own. The function:

Resolve the device

registry.activeDevice(agentId). This reverts if the device was revoked or the NFT owner changed.

Check freshness

NonceUsed if this nonce was already accepted. StaleProof if timestamp is more than 10 minutes old. FutureProof if it is more than 2 minutes ahead of the block.

Check the signature

The digest from hashActionProof must recover to the active device. Otherwise BadSignature.

Check operator approval

The owner must have setApprovalForAll this contract, or approved it for this token. Otherwise NotOperator. ERC-8004 only lets an owner or operator open validationRequest.

Write the validation

Computes requestHash and calls validationRequest then validationResponse on the Validation Registry. Response is 100, the response hash is paramsHash, the tag is kinetic-action, and the response URI is empty.

requestHash = keccak256(abi.encode(
    agentId,
    action,
    paramsHash,
    keccak256(bytes(requestURI)),
    timestamp,
    nonce
))

Emits Attested(agentId, device, requestHash, action).

This contract never calls giveFeedback, and it never approves the device key on the agent NFT. The signature shows the device authorized this record. It does not prove the actuator physically moved.

Views

View	Returns
`hashActionProof(proof)`	The EIP-712 digest the device signs
`nonceUsed(agentId, nonce)`	Whether this nonce has been consumed
`registry`, `identity`, `validation`	The KineticRegistry, Identity Registry, and Validation Registry

Errors

Error	Cause
`BadSignature`	The signer is not the active device.
`StaleProof`	The timestamp is older than 10 minutes.
`FutureProof`	The timestamp is more than 2 minutes ahead.
`NonceUsed`	This nonce was already attested for this agent.
`NotOperator`	The owner has not approved the attestor on the agent NFT.
`ZeroAddress`	The constructor was given a zero registry or validation address.
