Decision records capture the reasoning behind a real engineering choice, stated with the alternative that was rejected and the evidence that settled it. They are the counterpart to the notes: a note shows how something works, a decision record shows why it was built this way. Every record here refers to a choice this site (or its deployment) actually made and can be traced to a source.
The site is served as a static tree, not by a dynamic application server
ADR — static artifacts over application servers, with a narrow, nameable boundary.
