# WeChat Mini Program service-level + endpoint-level metrics from the
# mini-program-monitor SDK. Filter gates the rule to traffic carrying
# miniprogram.platform == "wechat" so the WeChat and Alipay rules do not
# double-count.
#
# expSuffix is intentionally empty — each rule explicitly chains
# .service(...) or .endpoint(...) so service-scoped and endpoint-scoped
# rules coexist in one file (APISIX pattern). A non-empty expSuffix
# would append .service(...) at the tail and override the endpoint
# scope on the endpoint-* rules.
