+ * #8965 — Antigravity quota reads must use the runtime host (daily-cloudcode-pa)
+ * instead of hardcoding cloudcode-pa.googleapis.com.
+ *
+ * Antigravity inference, credit probe, OAuth, and the models catalog all use
+ * ANTIGRAVITY_RUNTIME_BASE_URLS which starts with daily-cloudcode-pa.googleapis.com.
+ * The two quota RPCs (retrieveUserQuota, retrieveUserQuotaSummary) were hardcoded
+ * to cloudcode-pa.googleapis.com, so when only the runtime host serves them, the
+ * live quota signal is lost and falls back to fetchAvailableModels.
+ *
+ * This regression test stubs globalThis.fetch so ONLY daily-cloudcode-pa serves
+ * the RPCs (cloudcode-pa returns 500), then asserts:
+ *  1. retrieveUserQuota is the quota source (not fetchAvailableModels)
+ *  2. Weekly bucket data is populated (not lost)
