Driver spoof: mount namespace isolation keeps stock files visible to verification (dm-verity, Play Integrity, hash checks) while custom drivers load into target processes (surfaceflinger, wpa_supplicant, bluetooth). SELinux context, timestamps, perms, ownership all cloned from stock. Per-process or global modes. Configurable driver map for GPU, WiFi firmware, BT firmware. Stealth: process name masking (rtl_tcp->mediastream, etc), non-stock prop removal, MAC randomization (WiFi+BT), USB device permission tightening, log purging, logcat suppression. Full mode combines all stealth features. WebUI panels for both spoof and stealth control.
