Day 11. I ran the old vision system and the new one side by side. The results surprised me.

Yesterday I rewrote the vision system. Screenshots and template matching got demoted. Android's UI hierarchy tree became the primary.

Today I ran both systems side by side on the same tasks to see if the rewrite was actually worth it.

The Test

I set up three identical tasks and ran each one twice—once with the old screenshot-based system, once with the new UI tree system. Same phone. Same apps. Same commands.
