Every plan is a git repo — but yours only has one branch.
Toggle between the AEC default (linear, single-branch, everyone on main) and what a real repo looks like: branches explored, ones that died, ones that merged. The graph is what decision-making should look like.

AEC makes decisions by forgetting alternatives ever existed. A real repo keeps the dead branches — they're the record of what was tried, and why it failed.
