The CA-file assertion compared the option's raw string, so
`/var/lib//swarm-ca/root.pem` or `/var/lib/hive-tls/./ca.pem` got past it.
Both sides are normalised lexically now: empty and `.` components drop out,
`..` removes the one before it, a trailing `/` goes. A symlink is not
resolved at eval time, so a path through one still passes; docs/swarm/ca.md
says so.
- swarm-services-cert (and its daily renewal) treats a services leaf that
`openssl verify` rejects against swarm-services-root.pem as invalid and
asks the store for a new one, as hive-tls-resign already does for the
gateway leaf. The trust bundle is that root alone, so a leaf under any
other issuer verifies for no consumer. With the store unreachable the
unit fails, and where the gateway waits for the leaf, the import fails
with it.
- Every host also deletes the old hive CA's ca.srl and .swarm-ca-adopted
in deploy.hive-controller.tls.stateDir, with the same tmpfiles `r`
rules as ca.pem/ca-previous.pem/ca-key.pem. Nothing reads either.
- docs/swarm/ca.md: the services leaf's re-issue conditions, the two
extra deleted files, and that the deletion is irreversible: rolling back
to a generation with swarm-ca.service mints a new, unrelated root that
nothing issues under.
module-eval hive-tls: a case for the services-leaf check in the boot
issuance and the renewal (red with the line removed), and the deletion
case covers the two extra files.

The gateway leaf comes from the store's pki mount, so a hive CA's
certificates anchor nothing and its key is a secret outside the store.
- hive-tls-ca writes trust-bundle.pem from swarm-services-root.pem alone;
the ca.pem and ca-previous.pem slots are gone.
- Every host deletes ca.pem, ca-previous.pem and ca-key.pem in
deploy.hive-controller.tls.stateDir with tmpfiles `r` rules that follow
the option. The removal shim, now host-ca-removed.nix, holds these
beside the /var/lib/swarm-ca rule and the swarm.ca.* removals.
- deploy.bao.clientCaFile, deploy.bao.serverCaFile and
deploy.swarm-controller.hiveClientCaFile naming /var/lib/swarm-ca or one
of the deleted hive CA files fail evaluation, naming the store's mTLS CA
(/var/lib/swarm-bao-pki/ca.pem on the store's host) as the replacement.
module-eval hive-tls covers the single-anchor bundle, the deletion (incl.
a relocated stateDir) and the assertion on all three options.
