The problem
[ the situation the build answered — who was stuck, on what, and why it was worth the effort. stated the way it was found, not the way it would be pitched ]
[ constraints worth naming: time, tools, what could not change ]
The system
[ the shape of the solution in plain words — what talks to what, and why that shape and not another ]
Decisions that mattered
[ two or three forks in the road, the option taken at each, and what it cost ]
Where it stands
[ honest state today — live, shelved, or still moving — and what would come next ]
