No new teaching. Time to finish, so your system ships instead of stalling. One or two build-support office hours for unblocking.

Bring specific problems: a failing eval, a flaky tool, a deployment error, or a memory write that does not survive restart. Not "how's it looking."

If you are unsure whether your project is strong enough for Demo Day, ask in office hours or message the instructor. Better to course-correct now than freeze for two weeks.
