Lab: Discovery from Joan's desk to signed scope

Module 3 · Lab · About 60 minutes · Needs: lessons 1 and 2 (shadowing, the process map, hidden rules, the baseline and the scope page)

What you are building

Module 3 adds the first written piece of the engagement: Joan's process map, the problem statement, the baseline and the target. The two lessons built each part on its own. This lab runs discovery end to end, as one pass over one week's evidence, and leaves three files in the repository's discovery/ folder: process_map.csv, hidden_rules.json and scope.md. Every number on the scope page is computed from the files before it, so when Joan corrects a step or Rafael disputes a figure, you change the evidence and run the lab again. The running example is HF-88190, Greenway Garden Centre's missing shipment, which you watched Joan work on Monday 16 March. All the data is simulated.
