One platform MCP server: every tool result carries its door URL, so the human twin travels with the machine result.

The gates, typed.

Every gated action returns a typed OFFER or a NEEDS_HUMAN Handoff.

Posted price · hard ceiling · settle paths. A gate without one is a conformance failure on these rails. Worst-case cost is posted before the call.
