      Is Object.freeze on an object enough to ensure security/integrity when sharing an object across multiple realms? ie. no way to modify.

      for 1 level deep? yes, but they might still access variables / crawl prototype chain and mutate the origin realm

      approaches to happily send data across realms: Proxy membrane, freeze(create(null)) as ref, strings (JSON/URL.createObjectURL)

      has anyone published a generic Proxy membrane yet? And can they really not be pierced?

      host realm like Function.prototype.constructor, and freezing all built-ins. not sure if that's reliable/safe?
