Module 16 · Lesson 1 · About 60 minutes · Needs: Module 13's lab (the eval gate, python -m evals.gate), Module 15 (the queue and worker); Docker basics from Module 1The situation
Thursday 2 July 2026, week 12. Full launch is on Monday.
On 23 June a prompt change shipped without the eval gate, and Dev rolled it back by hand the same day. Module 13 built the gate. Priya asks: "If something gets past it, can it reach a few customers first, and how fast can we undo it?" Sam asks where the keys will live. Dev wants one image to run anywhere. This lesson follows the 23 June change through all of it.
