MainStreet — verifiable reputation signal to feed the Reputation Registry (open source)

[philpof102-svg]

Hi ChaosChain team —

You implement ERC-8004 identity + a Reputation Registry (signed int128 feedback) + a
Validation Registry, plus a decentralized x402 facilitator. The piece that pairs with it:
a verifiable reputation signal to feed the registry and to gate settlement.

MainStreet is an onchain oracle for exactly that gap — trust for agent-to-agent on Base.
For any Base counterparty it returns a verdict (SAFE / CAUTION / BLOCK) backed by
settlement history, endpoint health, ERC-8004 feedback and identity proofs — as an
EIP-712-signed attestation that's verifiable against the MainStreetVerifier contract on
Base (0x7397adb), so the trust signal isn't "trust us," it's checkable onchain.

As a feeder it can write signed scores into your Reputation Registry; on the buyer side
it's a pre-settlement check on the payTo before your facilitator settles x402:

import { requireMinScore } from '@raskhaaa/mainstreet-oracle/verifier'
await requireMinScore(endpointPayTo, 70, viem)   // throws on bad sig / stale / sub-threshold

Reference implementation (the orchestrator-gate pattern):

Fully open source. Is a reputation feeder useful to the RI? Happy to share the attestation
format / verifier ABI, or open a PR with a reference adapter.
