软件工程: 架构决策记录

An architecture decision record is a short document that captures one significant technical choice, the context that forced it, and the consequences of going that way. Teams keep them in source control next to the code, write them in plain Markdown, and treat each one as immutable once accepted. ADRs answer the question every new engineer asks six months in: "why did we build it like this?" If your documentation strategy has a gap where decision history should be, an ADR archive fills it.
