The conversation turn engine now records precise timestamps for when the assistant's first text becomes visible, distinguishing a block_complete paint (a tool result shown mid-turn) from a turn_end paint (text held until the turn finishes while the streaming preview is in focus mode). This is internal telemetry for query timing spans, not a user-facing setting.
