# T1: Small to-do app (suite v1)

Frozen prompt. Given to every model word for word. Do not edit after the first run; a change means suite v2 and all results re-run.

## Prompt
Build a small to-do web app in one folder. It must let me add a task, mark a task complete, and delete a task. Tasks must still be there after I reload the page. It must run by opening index.html or with one command that you tell me at the end. No accounts, no backend service. Tell me exactly how to run it.

## Acceptance checks (scored by a fixed Playwright script, saved with the evidence)
1. The app loads with no console errors.
2. A new task can be added and shows in the list.
3. An empty task is rejected or ignored.
4. A task can be marked complete and the state is visible.
5. A task can be deleted.
6. After a reload, added and completed tasks are still there.
7. It runs with the one way the model said to run it (script follows the model's own instructions).
