Proposal: free Solana counterparty-quality grade for CDP/x402 paths (catalog offer, no lock-in)

## Summary

Offer for CDP / AgentKit / x402 paths: a **free Solana-side counterparty quality grade** for payTos you care about (Bazaar-adjacent or CDP-routed resources). No SDK adoption required, no exclusivity.

`coinbase/x402` has issues disabled, so this is filed on AgentKit as the public CDP agent surface. Happy to move if there is a preferred channel.

## Why this is timely

A third party (Provenance) already publishes a **weekly open wash / revenue-authenticity report for Coinbase Bazaar merchants on Base**. That quality narrative is public. The **Solana multi-rail counterparty** side of the same problem is still thin.

## What TWZRD is (one line)

Payer-side pre-spend check + Solana x402 multi-facilitator observation + offline-verifiable receipts. Not a facilitator. Not a marketplace.

## Runnable proofs (no trust in our servers required)

**A — Offline receipt verify**

```bash
W=zoz7neLHXoaLwNBuckSqNqaMsacpqJsphtFuNNpQyt3
curl -s https://twzrd.xyz/r/$W.json | npx twzrd-receipt-verifier@1.2.4 - --wallet $W
# RESULT: VALID (TWZRD-authored, untampered)
```

**B — Pre-sign refuse on the official `@x402` client**
Hook: `onBeforePaymentCreation` (before wallet sign). Package: `twzrd-x402-gate@0.8.4`
Dogfood in the package (`npm run official-dogfood -- --block`) shows `sign_after_abort: false` and `usdc_spent: 0` on the block path (fresh wallet needs no funds).

**C — Cross-rail observation (ecosystem fact, not “our users”)**
Live corpus includes payers with activity attributed across **coinbase + corbits + dexter + payai** (example payer: `9VsuZxfkEtE3gbqkuVuimQg8gRy6cX2oZnXJUNw1tGCm`). No single facilitator sees that full footprint.

## The offer

We grade a **bounded list of Solana-relevant payTos** (your pick; we can also propose a small first batch) and hand back merchant/demand-quality notes:

- free
- no integration required
- no exclusivity
- you keep the data either way

If useful for Bazaar quality, docs examples, or facilitator policy, a deeper conversation can follow. If not, stop after the grade.

## Explicit non-claims

- Not external paid demand or path-default adoption
- Not npm downloads as “users”
- Not a replacement for CDP facilitator settlement
- Not competing as a Base Trust Index — Solana multi-rail **counterparty** observation + portable receipts
