biao-ben-priority
When the user faces multiple problems that need to be handled simultaneously and is unsure of their priorities; when surface symptoms and root causes are intertwined and it is unclear which should be addressed first; when the problems can be divided into "earlier-onset" and "later-onset" ones. Not applicable to: scenarios with only one clear problem; a set of independent problems with no causal relationship among them; emergency crisis handling (which requires stabilizing first before analysis).
