## Acceptance Gates

- External builder page includes a Packrift shelf snippet with a source slug that matches the partner or storefront.
- Packrift receives a source-attributed script/resource read, start, install/config, or first-run event from that external surface.
- Buyer clicks use the source-aware order handoff URL and preserve mcp_source_context into MCP live checks and measured cart URLs.
- Goal completion still requires external builder inclusion plus source-attributed cart/order proof; hosted demos alone are not completion proof.
