The controller grants a read only from the owner's announcement (ADR 0495 clause 3). gitea announced `bound`
unreadable, so mesh-provisioner bound no forge account; disk-load announced `readings` unreadable, refused to restic,
nfs-server and mounts; restic announced `good` unreadable, which the self-check reads. Nothing in the catalogue
compared readers with announcements since the gate's manifest check went (clause 5).
Quick fix: mark those three states readable. Thorough fix: also checks/readable, which reads every owner's Go and
TypeScript announcement and refuses any `reads` of a state it does not announce readable, so the next owner to
announce cannot repeat it. Chose thorough: the same kind hit three owners at once.
Reads of other repositories' owners (mesh-controller.lease, mesh-grants.accounts) are not judged here.
