Day 86 · Week 13
Week 13 · Build our next increment
Scheduled session · Tuesday, 8 December 2026
Our planned session
We add Pydantic input validation and a small response model.
Weekly outcome
One bounded FastAPI text endpoint with a tested contract.
Readiness check
We build on Week 12: A tested Python text utility we can explain from TypeScript knowledge. If its required checks remain incomplete, we use this week to finish or reduce scope first.
Human approval gate
We prove valid input returns the documented result and malformed input receives a predictable error.
