# Mattermost upgrade verification.
# ---------------------------------------------------------------------------
# Mattermost migrates its schema on boot and refuses to serve the API until it
# has finished, so a 200 from the ping endpoint carrying the new version is
# evidence the migration completed.
#
# /api/v4/system/ping is unauthenticated. The version is NOT in the body — it
# rides in the X-Version-Id header, as
# "11.9.1.311276...<hash>.false": build version first, then metadata. The shared
# comparison reads leading numbers, so it matches the 11.9 tag against the
# 11.9.1 build without needing to know that layout.
