Lab: Close the engagement, open the portfolio

Module 15 · Lab · About 60 minutes · Needs: lessons 1 and 2 of this module (decision records, the won't-build list, the post-mortem, anonymising a write-up)

What you are building

Friday 25 September 2026. Carol's plan is due today, and with it the engagement closes for good: the assistant belongs to Harbourline, Mei owns it, and your next customer starts soon. This lab is the course's last piece of the repository. You turn twelve weeks of harbourline-claims into something you can show.

Six files, each with a check in plain Python: a dated won't-build list, three decision records for Carol's asks, a blameless post-mortem, a pattern library, a public write-up with no identifying details, and a README that leads a stranger through it all. There is no model call. Everything at Harbourline is simulated, and so is everything in these files.
