Cybernetic Thinking

A cybernetic worldview for writing and debugging software, distilled from two books:

• Qian Xuesen (钱学森) & Song Jian (宋健), Engineering Cybernetics (工程控制论) — the mathematical foundations: stability, feedback, multivariable decoupling, disturbance compensation, bounded control, discrete systems.
• Jin Guantao (金观涛), Cybernetics and Scientific Methodology (控制论与科学方法论) — the epistemological foundations: possibility space, conjugate control, black-box recognition, information–control dependence, ultra-stability, bifurcation, catastrophe.

Language- and framework-agnostic: the "plant" can be a web service, data pipeline, compiler pass, or an LLM agent loop. Self-contained and usable on its own — no other skill required.
