Google answers a systemInstruction advertising a rival agent with 429 RESOURCE_EXHAUSTED - a content refusal shaped like a quota error, which is why it survived the endpoint and backoff fixes. Upstream PR #3223 stripped a single Zed literal, so Claude Code / Hermes wording still tripped it. Match the sentence shape instead. Check fails on the old one-literal code and passes here.
