these content errors are retried mid-stream (bounded by MID_STREAM_RETRY_OPTIONS), and for thinking-only / empty-text responses a nudge message is added on retry.\n\nFix status: documented_behavior\n\nLimitations:\n- Source is the published @google/gemini-cli 0.61.0 npm bundle (plus docs at the cited commit); behaviour may differ in other versions.\n- Not reproduced in this session.\n\nOther error fragments:\n- Model stream ended with malformed function call.\n- Model stream ended without a finish reason.\n- Model stream ended due to safety settings (SAFETY) with empty response text.\n- Model stream ended due to token limit exhaustion (MAX_TOKENS) with empty response text.\n- Model stream ended with empty response text but contained reasoning thoughts.\n- Model stream ended with unexpected tool call.\n\nEvidence (public sources, summarized;
