Stages TWRP's GUI engine and standalone tooling as PawletOS-owned modules instead of a bootable/recovery fork, per the plugin-architecture finding in NOTES-ota-recovery-ab.md: stock recovery_main.cpp already dlopen()s librecovery_ui_ext.so and dlsym()s make_device() from it at runtime, so the UI layer doesn't require touching stock bootable/recovery at all. Confirmed via source grep that recovery.cpp/install.cpp have zero references into the partition manager/backup engine/GUI code and vice versa. recovery_ui/: TWRP's gui/, minuitwrp/, libpixelflinger/ (copied verbatim, GPL-3.0), plus a new device/ providing PawletTwrpUI (a ScreenRecoveryUI subclass) and make_device() — written from scratch against stock's RecoveryUI/ScreenRecoveryUI virtual-method contract, since TWRP's own fork never ships a make_device() (every real TWRP device provides its own, and no reference device tree was available to copy from). Top-level Android.bp defines librecovery_ui_pawlet_twrp, the module TARGET_RECOVERY_UI_LIB should point at. gui/Android.bp and minuitwrp/Android.bp had their include_dirs rewritten for the new paths. recovery_toolkit/: partition manager, backup engine (tar/digest/adbbu/apex), filesystem/format support (exfat/dosfstools/gpt/fuse/mtp/crypto), scripting (openrecoveryscript/orscmd/twrpinstall), shared helpers. Source only, no Android.bp yet for any of it. Known gap blocking recovery_ui from actually linking: gui/'s libguitwrp depends on libaosprecovery, built from recovery_toolkit/helpers/twrp.cpp via a Go Soong plugin (libaosprecovery_defaults.go) not yet ported. Neither repo has been build-tested — no local AOSP build environment available in this workspace. See each directory's README.md for a precise done/not-done breakdown.
