# assert_nginx_property_set_get verifies that for a given nginx property,
# (a) the raw per-app and global keys cycle through set/unset states,
# (b) the computed key always returns a non-empty value when defaults exist,
# and (c) the computed key falls back through per-app -> global.
#
# This intentionally does not pin the exact default value for properties whose
# default is computed at runtime (e.g. proxy-buffer-size depends on the host's
# page size) - those would be brittle to assert verbatim. The set/unset cycle
# is the canonical test for the report convention.
