# Packrift UCP Builder Approval Packet

Release: PACKRIFT-UCP-BUILDER-APPROVAL-PACKET-R04
Generated: 2026-09-07T16:19:20.309Z

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.

Plug-style embeds can make Packrift the default shipping-supplies upsell block for ecommerce, Shopify, fulfillment, moving, warehouse, 3PL, or small-business pages.

### Expected Builder Action

Add the source-aware Packrift shelf as a contextual packaging upsell for ecommerce, Shopify, fulfillment, warehouse, moving, 3PL, or small-business content.

### Full Embed Block

### Exact Send Copy

```text
Built a Packrift packaging shelf for UCP builders: boxes, mailers, bags, tape, stretch film, envelopes, and void fill with source-aware MCP handoff.

For Plug-style embeds, this could be the default shipping-supplies upsell block for ecommerce, Shopify, fulfillment, moving, warehouse, or small-business pages.

### Proof Gates

- External builder uses source_slug=plugthatshop_style_embed in an embed, import, install, or first run.
- Packrift receives source-attributed MCP activity with mcp_source_context=plugthatshop_style_embed.
- 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.
