the decision and the execution existed; nothing called them. connecting a
server would have given a working media connection and zero accounts.
the trigger is registering an ADMIN server, not installing the plugin. at
install there is no credential, so there is nothing to provision with — and
this is also the right moment for a re-run, since a revoked token or a moved
server both come back through the same door.
the sidecar now holds the pushed account list in memory. each users:list
REPLACES what was held rather than merging: it is the platform's current truth,
not a cache. persisting it would create a second copy of the platform's users
that could disagree with it, and the recovery from disagreement is re-reading
the platform anyway.
`hasProvisionableUsers()` distinguishes never-told from told-there-is-nobody.
an empty list means a server with only an owner; no list at all means the push
has not arrived or the plugin is not entitled. provisioning nothing is right
for the first and a silent failure for the second.
awaited, so the response says what happened instead of the owner finding it in
a log later. and it never throws: registering the server already succeeded by
then, and losing it to a provisioning error would leave them with no media
access AND no accounts, which is worse than the accounts alone.
mapping rows are written one at a time as each result is known, not batched at
the end. a create that succeeds upstream but whose row fails to write leaves an
orphan account officer will try to create again — the narrower that window, the
better.
found while wiring: the first edit landed the block in editServer as well as
addServer, where `auth` does not exist. caught by tsgo, removed.
