Built-in-agent rides the OpenAI Responses API, which mints non-deterministic `fc-*` function-call IDs (not the canonical `call_d5_*` ID we emit), so the post-tool follow-up cannot pin on toolCallId like LGP does. AND the 3-pill probe carries prior tool results across turns, so hasToolResult: false fails after the first pill. We use sequenceIndex: 0 to gate the 1st-leg fixture to the FIRST time this pill's userMessage is matched; once exhausted the post-tool fixture below (no sequenceIndex) catches the 2nd-leg request.",
