- Replace bad_query with forcequitOS/worse_query (App Group based)
- Read the App Group from the code signature entitlements
- Add pathleak container enumeration and iOS 27 system container lookup
- Route descriptor/CarPlay writes through worse_query
- Add sign_personal.sh and POCKET_POSTER_SELFTEST diagnostics
- Keep bad_query as an iOS 26 fallback
