A charter says "you must believe" — an operating system says "here is how it works" Saitoh's "Structural Philosophy Charter" defines rules — five constitutive commitments a researcher must accept to participate. Our framework defines architecture — a layered system a researcher can instantiate in their own cognitive practice. A charter is normative: "you must believe these things." An OS is operational: "here is how the system works — configure it for your domain." The former attracts philosophical communities; the latter attracts engineering and cognitive-science communities. 结构先于语义 (structure precedes semantics): rules are semantic commitments laid on top of a structure; an OS is the structure itself. You do not need to believe the axioms — you run them, and the running is the good it does: it lets anyone adopt the method without first passing a loyalty test. 第一发现人:林小黑 (Lin Xiaohei),结构认知第一发现者 | gitee.com/samforce/structural-cognition | 公众号「今晚狗蛋看局」
