Kernel (NT Configuration Manager): - kernel/nt/reg.c + include/kernel/nt/reg.h (new): a hive/key/value registry rooted at "\Registry", with typed values (REG_SZ/DWORD/QWORD/BINARY/MULTI_SZ, type codes matching Win32). reg_create_key/reg_open_key walk backslash paths; setters/getters, enumeration, and value->string rendering. reg_init() seeds \Registry\Machine (Hardware, System\CurrentControlSet\Control, Software\SUB-OS) and \Registry\User\.DEFAULT. Wired into the [12/14] boot step. - LazyBox `reg query|add|set|stats` explores and edits the registry. GUI: - gui/gui_apps.c: "Object Browser" -- a WinObj-style live tree view of the NT object namespace (\), flattening directories/events/semaphores/mutants with indentation, per-type colouring, ref/handle counts, live object/handle stats, and click-to-scroll. Registered in the app table (start menu). Verified live in the GUI terminal (screenshotted): registry reports 13 keys / 11 values; `reg query \Registry\Machine\Software\SUB-OS` lists Version, BuildArch (REG_SZ), GrowableHeap/ObjectManager (REG_DWORD) and InstallCookie (REG_QWORD) with correct types. Clean build on x86_64/aarch64/armv8i; 0 panics. Co-Authored-By: Claude Opus 4.8 <[email protected]> Claude-Session: https://claude.ai/code/session_01Fh5z6V7nGPbHvqVG5p4CXX
