The universal PARALLEL_TOOL_CALL_GUIDANCE block already lives on main, but it shipped with two rough edges this change cleans up: - It duplicated the batching steer for Google models. The GOOGLE_MODEL_OPERATIONAL_GUIDANCE block still carried its own "Parallel tool calls" bullet, so Gemini/Gemma received the instruction twice in one prompt. Drop the redundant bullet — the universal block is now the single source. - Its comment claimed "nothing in the open-source system prompt encouraged batching," which was wrong: the steer existed for Google models only. Reword to say the gap was that every *other* model got nothing. - Tighten the test that asserts the steer (precedence-correct), and add an invariant guarding against re-introducing the Google duplicate.
