-"""Regression test for Magisk.setup() permissions on the /data/adb/magisk copy.
-
-install() runs copy() -> extra1() -> set_perm(). set_perm() only walks self.files,
-which are paths under copy_dir (the overlay), so the copy that setup() makes into
-<data>/adb/magisk keeps the 0644 the binaries inherit from the apk extraction.
-
-A non-executable /data/adb/magisk/magisk64 makes magisk_env() abort at post-fs-data.
-Root still works (it runs from the overlay copy), but Zygisk never initialises and
-the Magisk app reports "Zygisk: No" with no error explaining why.
-
-Runs as an ordinary user, needs no Waydroid install and no extra dependencies:
