A short closing from David — about five minutes — before you go.

What you actually have now

Five capabilities, practised rather than described:

Studio What you practised What you keep
1 — SEE Separating the problem from the solution before you solve Four Conversations Field Log
2 — THINK Staying in a conversation long enough for the design to change Discovery Conversation Transcript
3 — DESIGN Reading design through what can be independently verified Testability Review Card
4 — BUILD Keeping shared understanding alive while AI participates Collaboration Protocol
5 — REFLECT Studying the traces of your own work Personal Learning Loop

The through-line

Nothing about good software engineering changed. Everything about how we practice it did.

Understand the problem before solving it. Design for change. Keep it simple and verifiable. Collaborate honestly. Keep learning. Those were true before AI and they are more true now — because AI amplifies whatever you bring to it.

That is why this was never a tooling course. Tools change. What you practised does not.

What to do on Monday

Not all five. Pick one — the micro-habit you chose in Studio 5. Use it on real work for two weeks, then look at what changed.

Small enough to keep is the only kind of practice that compounds.
