The traffic poll read every Xray counter in one QueryStats reply under
gRPC's default 4 MiB receive limit; past it the whole poll failed and
no client was counted, so quotas stopped being enforced. Outbound
counters carry tags derived from third-party link remarks, so one long
remark was enough.
Poll the user, inbound and outbound families separately with a 64 MiB
limit, keep counting the families that answer, and cap a subscription
link's slug at 64 runes so the tag stays small to begin with.
