Build NotesThe question
What changed?
Start with the tension, then let the code earn the answer.
?
const context = 'scattered';const handoff = 'slow'; // find the useful abstraction
The move
The smallest useful abstraction
One function. One promise. One place to change the story.
function composeSignal() { return context .filter(isUseful) .map(makeVisible) .join(' 鈫?');}
The difference
Make the handoff legible.
When the change is visible, the team can move without guessing.
- await Promise.all(tasks)+ await sequence(tasks)- hidden context+ visible next step
changed / 02 lines+ context 鈫?action
The result
Now the system has a shape.
Close with the result the viewer can remember and reuse.
measured outcome
One predictable handoff
42ms from intent to action.
The takeaway
Good systems make good work obvious.
Explain the change. Show the proof. Leave a reusable idea.
