Discovery
Two weeks beside the team. We time the operations, read a sample of the files, and write down the questions people already ask each other. The artefact is a short brief: one or two tasks where a system would change the week, the tasks we would leave alone, a first list of evaluation questions, and a constraint note on data residency. We have declined work at the end of discovery when the hours were real and the files could not support an answer. That is a successful sprint.
