// gateway, so its skills/tools/MCP must be read from and written to THAT
// machine's backend. Three shapes:
//   - no scope         → ambient profile + ambient registry connection tag
//   - string scope     → explicit profile, ambient connection tag
//   - object scope     → explicit (connection, profile) pin; 'local' pins the
//                        local pool and DROPS the ambient connection tag
