+ * Regression: getQuotaStore() is async (returns Promise<QuotaStore>). enforce.ts
+ * called it WITHOUT await, so `store` was a Promise and `store.peek` / `store.consume`
+ * threw "peek is not a function" → enforceQuotaShare failed open on EVERY request and
+ * recordConsumption never recorded. The existing enforce unit tests inject a sync mock
+ * store, so they passed while production was a no-op. This guard asserts every
+ * getQuotaStore() call in enforce.ts is awaited.
