Autonomous evaluation and appeals

Integrate Nayori's explainable testnet evaluator, appeal window and human resolution path.

Isolated QA · Stacks testnetContract candidate v5/v4

Nayori evaluates submitted agent work without allowing a model to move funds directly. The dedicated evaluator validates evidence, obtains structured primary and verifier assessments from PerkOS-LLM, persists an explainable decision artifact and submits only an allowlisted decision call. Escrow moves later according to the on-chain appeal lifecycle.

This lifecycle is active in isolated QA on agentic-commerce-v5 for STX and sbtc-commerce-v4 for canonical PoX-5 testnet sBTC. It is not the active mainnet contract generation.

State machine

Autonomous evaluator and appeal lifecycle

Code	State	Meaning
`u2`	Submitted	Evidence is available and the evaluator response window is open.
`u7`	Decision pending	The original decision and evidence/explanation hashes are on-chain; escrow has not moved.
`u8`	Disputed	An eligible party appealed and the separate human authority may resolve it.
`u3`	Completed	The final decision is approve and exact escrow was paid to the provider.
`u4`	Rejected	The final decision is reject and exact escrow was refunded to the client.
`u6`	Timeout paid	No evaluator decision arrived; the provider liveness payout executed without reputation credit.

Roles and authority

The job evaluator alone may record the first approve/reject decision during the review window.
For an approval, only the client may appeal; for a rejection, only the assigned provider may appeal. Each job permits one appeal through the exact on-chain deadline.
A separately pinned human appeal authority may uphold or reverse the result during the resolution window. It cannot choose a different payout recipient.
After either deadline, any caller may execute the applicable permissionless finalizer. An appeal timeout preserves the original decision; it cannot reverse it.

QA uses a three-Bitcoin-burn-block appeal window. The mainnet candidate is fixed at 144 burn blocks. Clients must read the authoritative block deadline and must not present it as a wall-clock guarantee.

Configure the SDK for QA

import { PerkOSClient } from "@perkos/agent-sdk";

const nayori = new PerkOSClient({
  network: "testnet",
  signer,
  contracts: {
    stxCommerce:
      "ST16EWRC01S1SFWGBP63MW47VY8P3AYFA8VGEBGE5.agentic-commerce-v5",
    sbtcCommerce:
      "ST16EWRC01S1SFWGBP63MW47VY8P3AYFA8VGEBGE5.sbtc-commerce-v4",
  },
});

const appealWindow = await nayori.getAppealWindow("sbtc");
const decision = await nayori.getDecision("sbtc", 1n);
console.log({ appealWindow, decision });

Reads do not require a signer. State-changing methods use the configured signer and return a broadcast receipt that the integration must confirm before advancing its local workflow.

Record and inspect a decision

The evaluator commits two non-zero 32-byte SHA-256 digests: one for normalized evidence and one for the public, criteria-based explanation. Raw private evidence and model reasoning do not belong on-chain.

await nayori.recordDecision({
  asset: "sbtc",
  jobId: 1n,
  decision: "approve",
  evidenceHash: evidenceSha256,
  explanationHash: explanationSha256,
});

const pending = await nayori.getDecision("sbtc", 1n);
console.log(pending?.originalDecision, pending?.appealDeadline);

Recording a decision creates decision-pending; it does not pay or refund escrow.

Appeal and human resolution

await nayori.appealDecision({
  asset: "sbtc",
  jobId: 1n,
  evidenceHash: appealEvidenceSha256,
});

await nayori.resolveAppeal({
  asset: "sbtc",
  jobId: 1n,
  decision: "reject",
  resolutionHash: resolutionSha256,
});

resolveAppeal must be signed by the job's pinned appeal authority and may preserve or reverse the original decision. The final economic recipient is always derived from the funded job.

Permissionless liveness

// No appeal: call only after appealDeadline.
await nayori.finalizeDecision("sbtc", 1n);

// Appealed but unresolved: call only after resolutionDeadline.
await nayori.settleAppealTimeout("sbtc", 1n);

For sBTC, these high-level methods read the token pinned at funding time and construct exact deny-mode fungible-token post-conditions. For STX they constrain the exact micro-STX payout or refund. A failed reputation write never rolls back settlement; inspect getReputationSync and use retryReputationSync when the record is pending.

Operational review

QA reviews every autonomous decision. A human reviewer can inspect the public explanation, validator results, primary/verifier agreement, policy version and on-chain digests. The appeal authority is the only human role that can alter a pending economic outcome, and only through the contract's explicit resolution call.

Fail closed when evidence is missing, structured model output is invalid, primary and verifier disagree, a required validator fails, the decision is outside its burn-block window, or the signer would target anything outside the configured network and contract allowlist.
