# Packrift UCP Builder Approval Packet

Release: PACKRIFT-UCP-BUILDER-APPROVAL-PACKET-R04
Generated: 2026-09-07T16:17:14.186Z

Owner-approval packet for turning Packrift UCP builder assets into real external storefront inclusion attempts, source-aware MCP runs, cart handoffs, and sales proof.

Completion boundary: This packet improves activation readiness. The distribution goal remains open until a real external builder embeds, installs, or uses Packrift and source-attributed MCP/cart/order proof exists.

## Policy

- External send requires Farhan approval.
- Do not send from an agent.
- Do not make purchases, paid submissions, product writes, pricing writes, inventory writes, or feed writes from this packet.
- Do not claim Packrift is the default supplier until external source-attributed proof exists.

Stack412-style sites prove the themed storefront pattern. Packrift should be pitched as a ready shipping-supplies or fulfillment-supplies category, not as a wellness-store placement.

### Expected Builder Action

Create a shipping-supplies or fulfillment-supplies category shelf backed by Packrift, rather than placing Packrift inside an unrelated niche storefront.

### Full Embed Block

```html
<div data-packrift-ucp-shelf data-source="stack412_style_storefront" data-limit="12"></div>
<script async src="https://mcp.packrift.com/ai/packrift-ucp-shelf.js?source=stack412_style_storefront&limit=12"></script>
```

### Exact Send Copy

```text
If you build more UCP storefronts, Packrift has a ready shipping-supplies aisle: boxes, mailers, poly bags, tape, stretch film, envelopes, and void fill.

```

### Proof Gates

- External builder uses source_slug=stack412_style_storefront in an embed, import, install, or first run.
- Packrift receives source-attributed MCP activity with mcp_source_context=stack412_style_storefront.
- A buyer-approved measured cart URL or /r/cart landing preserves the source slug.
- A Shopify order carries source-attributed MCP continuity before sales proof is claimed.
