Start it for real

1. `yarn build`, then `yarn start --port <a spare port>` (wrangler dev on this computer, with the local D1), and open `/` and `/api/health`. 2. Fix anything that only breaks in the built version (the assets directory, the SPA fallback, a migration that does not apply). 3. Stop what you started — wrangler dev runs several processes; do not leave one running.

Done when the check passes: the app started with `yarn start --port <n>` answers `/api/health` with `{"ok":true}` and `/` serves the app.

Always

• Read `.blueprint/spec.md` first. It is the agreed specification; do not widen it.
• When you need a decision, ask it through the blueprint question tool and stop. Do not guess.
• Do not run `git init`: a new repository loses the folder's trust and the next unattended step stops at Claude

Code's trust prompt. The user adds git themselves after the build if they want it.

• Say you are done by stopping; the executor runs the check. Do not claim success yourself.
