Follow-ups
Stay in the same depth. Agent chips deepen the prior topic.
Follow-ups stay on this Consultation at the same depth you already chose. A Research page does not silently drop to Quick because you clicked a chip.
Chips are agent-generated. They deepen the prior topic. They are not fixed heading templates and they are not a menu of new Create rows. Short deepen requests compound against the previous question so the engine expands that thread instead of cold-starting.
Change depth only when you mean to — use the rail Quick · Research · Reason control. Reason still bills at the Research rung. Starting a different specialist set or a Catalogue method means New → Consultation again.
