Day 172 · Week 25
Review, repair, and practise
Scheduled session · Thursday, 4 March 2027

Our planned session
We use 60 minutes to verify and repair this week’s slice, 20 minutes for the recurring practice below, and 10 minutes to record decisions. We carry unfinished work forward explicitly.
Weekly outcome
One versioned prompt improvement with a small regression gate.
Readiness check
We build on Week 24: A justified model choice for our existing summary task. If its required checks remain incomplete, we use this week to finish or reduce scope first.
Our 20-minute practice
We spend 20 minutes on one small JavaScript/TypeScript problem: first attempt, then agent critique and one test.
Human approval gate
We inspect the same evaluation cases and reject unsupported improvements or new critical failures.
