both of these approaches use NFAs under the hood, which means O(m * n) matching. our approach is fundamentally different: we encode lookaround information directly in the automaton via derivatives, which gives us O(n) matching with a small constant. the trade-off is that we restrict lookarounds to a normalized form (?<=R1)R2(?=R3) where R1/R2/R3 themselves don’t contain lookarounds. the oracle-based approaches support more general nesting, but pay for it in the matching loop. one open question i have is how they handle memory for the oracle table - if you read a gigabyte of text, do you keep a gigabyte-sized table in memory for each lookaround in the pattern?

这种“以量补价”的逻辑在集采初期还是非常值得一看，但在集采规则日益精细化、价值导向愈发明确的今天，其可持续性存疑。尤其是天星医疗的收入结构过于单一，这决定了公司对集采政策的敏感度远高于那些拥有多元化产品线的平台型巨头。
