§ 01

The loop that never closes.

Customer quote — DDD pilot
„I read Vernon three times. I still didn't know if I was doing it right.“
— Pilot participant, n = 14

You finish training. The book sits on your shelf. Monday comes. You ship something. Nobody tells you whether the boundaries are right, whether the scorecard would pass.

The anxiety never closes — it just gets filed under „delivery pressure“ filed away.

// Diagnosis: feedback-loop = none. Expected value: persistent.

§ 02

How an exercise works

You work in your own IDE on a real Git repo. The platform provides the exercise, tracks checkpoints, and delivers scorecard feedback.

  1. STEP 01
    Choose an exercise
    From your dashboard. Domain, checkpoints, scorecard — all visible before you start.
  2. STEP 02
    Clone starter repo
    The platform provisions a private Git repo with exercise files. Copy the URL or open in your IDE.
  3. STEP 03
    Work in your IDE
    VS Code, IntelliJ, Zed — anything goes. Markdown, diagrams, TypeScript. Your tools, your pace.
  4. STEP 04
    Commit + Push
    Git is the hand-off. No ZIP upload, no copy-paste. Push, and the platform detects it.
  5. STEP 05
    Submit — read the scorecard
    AI reviewer trained by Matthias scores each criterion. APPROVE or REQUEST_REVISION in 2–3 min.
// Revise and resubmit — as many times as you need. No one-shot exam. No deadline pressure.
§ 03
