需要注意的是，价格决定了复购的频次：再好的产品，如果价格过高，也无法实现高复购。去年我们打造的王繁星面馆，一年只开了80家店，我坚决不让它扩张到300、400家，就是因为现炒浇头面易被模仿，30多元的客单价，一旦在一个城市密集开店，必然陷入内卷，最终害人害己。对于高价品牌，必须“聚焦” “极致” “克制”——聚焦核心品类，产品品质做到极致，克制门店数量。
On top of that, the project uses a decentralized messaging fabric that can be REST, DIDComm, or another trust‑spanning protocol. This enables participants to establish relationships and exchange credentials without revealing their physical location or network topology. Each relationship uses its own random, ephemeral DIDs, making it far harder for observers running messaging infrastructure to infer who is talking to whom or to map the kernel's social graph.，更多细节参见同城约会

How often does the "slow path" actually trigger? With 32 TLB entries covering 128 KB, Intel claimed a 98% hit rate for typical workloads of the era. That sounds impressive, but a 2% miss rate means a page walk every 50 memory accesses -- still quite frequent. So the 386 overlaps page walks with normal instruction execution wherever possible. A dedicated hardware state machine performs each walk:
