Verified on a Pixel 4a (APatch, kernel 4.14) and a Pixel 8 Pro (KSU-Next + KPatch-Next-Module, GKI 6.1): - KPM runtime probe: drop the dead /data/adb/ksu/bin/kpatch guess (KSU-Next ships kpatch via the KPatch-Next-Module, not ksu/bin) and the unused PATH check. The real signals are /data/adb/ap (APatch — loads KPMs via supercall, no CLI on disk) and /data/adb/modules/KPatch-Next/bin/kpatch (the module, same on Magisk/KSU/KSU-Next). Mirror the same trim in the activator's find_kpatch and the KPM post-fs-data, documenting that APatch goes through the supercall. - root_manager: APatch and KSU both ship a /data/adb/magisk compat layer (the APatch 4a has /data/adb/magisk + magisk.db), so the old order reported APatch as 'magisk'. Check magisk first and let the exclusive ksu/ap dirs override it. - reword the KPM needs-runtime string: drop the misplaced 'APatch already includes it' note (an APatch user never sees this string — the runtime flag is already true via /data/adb/ap).
