Start by reproducing the Gemini 2.5 Flash Lite request and tracing how the provider handles the reported 429 RESOURCE_EXHAUSTED response. No files or tests are named; determine where this response becomes “Unknown error,” then verify that the resulting behavior distinguishes quota exhaustion and retry guidance from other failures.
