Decision graph

A decision graph for code is the connected record of the choices behind a codebase — what was decided, the reasoning, the alternatives ruled out — each one tied to the exact code it governs, so the “why” is queryable instead of lost.

Where it shows up

It’s the connected record of the choices behind your codebase. Agents read the relevant nodes before they build, and you can ask why any part is the way it is — the backbone of “keep the why.”
