Live settlement evidence

B03 / Gate P4 handoff artifact.

Status

LIVE_RUN

Live Arc Testnet settlement and policy denial drills have been executed and verified. Provisioning completed per docs/settlement/PROVIDER_SETUP.md with Privy application cmtqbf5zo013w0cky3r0jqjca, server execution wallet 0xfCC366c88A0c980e2FD5a7Cf7a36494E4457D943, policy balx3rtrpns3gnvhz3n32dml, and funded Arc Testnet account.

Evidence artifact: evidence/c06/sanitized-proof.json.

Settlement Status CONFIRMED

Observed Policy Denials (Zero External Broadcasts)

Two live negative tests were executed against Privy policy balx3rtrpns3gnvhz3n32dml prior to settlement:

  1. Unauthorized Recipient Denial:

    • Target recipient: 0x1111111111111111111111111111111111111111 (not in policy allowlist).
    • Privy response: HTTP 400 policy_violation (RPC request denied due to policy violation).
    • External broadcasts: 0.
    • Committed settlements: 0.

  2. Above-Cap Amount Denial:

    • Transfer amount: 2000000 atomic units (exceeds configured 1000000 cap).
    • Privy response: HTTP 400 policy_violation (RPC request denied due to policy violation).
    • External broadcasts: 0.
    • Committed settlements: 0.

On-chain nonce remained 0 across both denial tests; wallet balance remained unaffected until the single authorized settlement.

Lost-Hash & Lost-Response Recovery Drill

Simulated worker crash / network partition immediately following transaction submission:

  • Initial worker intent state: UNKNOWN.
  • Authoritative reconciliation lookup via Arc RPC verifyReceipt: confirmed on-chain settlement at block 61116056, log index 23.
  • Intent transitioned from UNKNOWN → COMMITTED.
  • External recovery submissions: 0 (no duplicate broadcast attempted).
  • Idempotent replay check: Replaying the business intent returned 200 REPLAYED with identical settlement binding and unchanged nonce. Exactly 1 intent → 1 settlement invariant preserved.

Historical Graph and Vertex AI Recovery Agent Observation

The historical record below used direct Studio data with the prior normalization metadata. It must not be described as an official Subgraph MCP call; fresh qualification evidence must use the active STUDIO_GRAPHQL source identity.

What is Proven

  • Privy Authorization: The corporate execution wallet strictly enforces policy rules on the normal path via eth_signTransaction. Disallowed recipients and above-cap amounts are rejected by Privy with zero on-chain transaction broadcast.
  • Arc Testnet Rail: Real USDC transfer on Arc Testnet succeeds, generating an exact EVM Transfer(from, to, value) log verified by verifyReceipt.
  • Durable Identity: Transaction hash, block number, block hash, and log index are deterministically bound to the durable business intent.
  • The Graph recovery observation: Historical direct Studio candidate discovery identified a matching USDC transfer; Vertex AI Gemini 2.5 Flash advised RECONCILE with traceable decision identity; the deterministic safety core verified Arc evidence with zero duplicate payments. The sponsor claim remains NOT VERIFIED until a fresh trace is captured through the active STUDIO_GRAPHQL path.
  • Fail-Closed Recovery: Unlearned outcomes and crashes preserve UNKNOWN state until verified; reconciliation performs read-only checks without duplicate settlement attempts.

Limitations

  • Arc Mainnet profile remains intentionally disabled (enabled: false, verification: UNPUBLISHED) pending production launch and human sign-off. Those are the values the profile actually carries in packages/arc-adapter/src/profiles.ts; the profile holds no chain ID, RPC, explorer, or token value at all.
  • Pinned deployment QmPEUSL6aXY7RVjGFFMbs5L4Q4pxG4TB73cHQ7nechGQY7 is live and synchronized via Subgraph Studio, whose endpoint is rate-limited and intended for testing/development; decentralized Network availability remains future infrastructure.
