A teammate suggests handing 2 of your sprint tasks to an AI agent end to end, to save time. The first is a Python script that backfills a denormalized display_name column across 40 million rows of users, reading from a profiles table. The second is unit tests for a pure date-formatting function you already wrote.

Does each task suit full delegation, and what separates them?
