# Matrix (Synapse) upgrade verification.
# ---------------------------------------------------------------------------
# Synapse runs database schema migrations on boot and does not serve until they
# finish, so "answering with the new version" is genuine evidence the rung
# landed rather than merely that a process started.
#
# /_synapse/admin/v1/server_version needs no authentication and returns the
# running version outright: {"server_version":"1.158.0"}. The tag carries a
# leading v (v1.158.0); the shared comparison comes down to numbers, so that
# difference does not matter.
