Homework after Session 4

Time: ~20 minutes. Lighter in this session, the gates are the next session.

1. Read the spec cold. Before the next session (not now), open the spec fresh and read it end to end. Mark anything you no longer agree with, anything vague, anything that's secretly two features, and look hardest at the shared data model, because three platforms are about to believe in it. Don't fix it, list it. Classic requirements-review discipline: a decision that survives a night's sleep is a decision; one that doesn't was a mood.

2. Bring to Session 5: your marked-up list from item 1. The gates will eat it for breakfast, that's what gates are for.
