Week 25 · Test and extend our increment
Scheduled session · Wednesday, 3 March 2027

Our planned session
We version one prompt change and rerun deterministic output checks.
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.
Human approval gate
We inspect the same evaluation cases and reject unsupported improvements or new critical failures.
