SubscriptionUsage

The one usage payload shape: the usage/read result’s usage member and the usage/changed params (ADR 32563 D2/D3). The numbers are point-in-time — observedAtMs is the host’s arrival stamp, so a client renders “as of”, never implies live data.

Fields and variants

• observedAtMs
• tier
• weekly
• window
