The four readers' ordering after their policy units only applies where the store and that reader share a host, so it is colocation glue and does not belong in the reader modules (two of which are main modules). glue-bao-readers-policy-order.nix now sets the after+wants edges, gated on deploy.bao.enable AND the reader's own gate, so a store host without a reader gains no stub unit.

# Glue: where the store and one of its readers share a host, the reader waits
|
|
# for the unit that writes the cert-auth role it logs in with.
|
|
#
|
|
# ONE PAIRING PER FILE — the store's four reader policy units ← the readers
|
|
# they grant, and nothing else. Deleting this leaves every reader as it is on a
|
|
# host whose store is remote: it may log in before its role exists, and its own
|
|
# retries are what carry it past that.
|
|
#
|
|
# ⚠️ Gated on BOTH the store and that reader being here. Off the store's host
|
|
# there is no local policy unit to order against. On the store's host without
|
|
# the reader, setting `systemd.services.<reader>.after` would define a unit
|
|
# with no ExecStart, so each gate below restates the one the reader's own
|
|
# module puts on it. A reader whose gate changes must change here too.
|
|
#
|
|
# Ordering, never a requirement: a policy unit skips once the bootstrap token
|
|
# is gone, and a skipped unit counts as done. `wants` as well as `after`, so a
|
|
# reader started on its own pulls its policy unit into the same transaction.
