Day 39 · Week 6
Review, repair, and practise
Scheduled session · Thursday, 22 October 2026

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
A mobile create-and-list flow with runtime input validation.
Readiness check
We build on Week 5: The mobile app reads a sample entry from a Node.js API. If its required checks remain incomplete, we use this week to finish or reduce scope first.
Our 20-minute practice
We spend 20 minutes explaining this week’s design tradeoff aloud, including a failure case and a simple diagram.
Human approval gate
We create an entry from mobile and reject malformed API input without a server crash.
