The owner installs, but a server may already have members, and a member added next month needs the same
work. So the unit is (service × member) reachable from two triggers — install a service, provision
existing members; add a member, provision installed services — rather than a loop inside the installer.
Only handling the first works on day one and rots.
No new table. A member is provisioned exactly when they hold a service_connections row: their own
credential, url NULL, inheriting the instance from the owner's. That schema anticipated this before this
existed, and a second record of the same fact would only be able to disagree with the first.
Three outcomes, declared per catalogue entry so the installer never special-cases a service. `accounts`
is fully transparent. `none` is a single-tenant daemon with nothing to do — filtered before the
provisioning loop so callers can tell "nothing to do" from "did nothing", which look identical at a call
site and matter when someone is asking why a member cannot see a feature.
`invite` is not a weaker `accounts`, it is the correct outcome: Vaultwarden derives its encryption key
from the master password, so a credential we could mint would mean a vault we could read. Transparent
right up to where being transparent would be a defect.
The per-service work is an interface implemented beside each sidecar rather than a switch in core — a
central function growing a case per service is what would stop any of this shipping from its own
repository. Implementations must be idempotent, since both triggers can fire for the same pair and a
duplicate account upstream is not ours to undo. Deprovision is optional and defaults to leaving the
upstream account alone: deleting an Immich user deletes their photos.
Written assuming the vault's multi-user adaptation has landed. Today /api/vault is owner-only by an
explicit ownerGate, so a member is refused before Vaultwarden is reached — verified, and out of scope.
