The mesh writes its own user list, and at genesis there is no mesh yet to write it. So the installer carries the first one — the controller's own account at a well-known bootstrap password, exactly as the store is reached at `postgres:bootstrap` and the old bus at `guest:guest`, and rotated with them. From the controller's first composition onward the file is the controller's. That left a gap I would not have found by reading: the controller's own account is created before there is a controller to mint one, so nothing recorded a hash for it, and its first composition would have left the writer out of the file it was writing — a bus nothing can connect to, produced by the thing connected to it. It now records a hash of the credential it is actually using, and only if none is recorded, so a restart cannot put the bootstrap password back over a rotated one. The carried list and the derived one are two statements of one fact, so a test compares them: every subject the controller derives must be in the template, and nothing wider. It earned itself immediately — the composer was granting both a role's whole event branch and the one event it actually follows, which is a wider way of saying the same thing, and the wider one wins. Only the submitting half of a role is granted now; what comes back is named exactly. Getting this wrong is the worst kind of silent. A controller whose carried permissions are narrower than the ones it derives comes up, connects, and is refused on the first thing it tries, with an authorisation error naming a subject and not the template that forgot it — and a mesh cannot be raised twice to find out.
