about

nx_nishios_shell.nx -- NishiOS GUI rung-6: the terminal runs a REAL tool (`ls` over the real FS). rung-5 made the terminal typeable with builtins; this makes it a real SHELL: typing "ls" dispatches to an actual directory listing via sys_openat_rd + sys_getdents64 + dirent_name (the same syscalls the sovereign coreutils `ls` uses), reading the REAL knowledge/status directory and rendering the entries in the terminal. GUI keystrokes -> shell -> real kernel syscalls -> real filesystem -> pixels. KAT: typing "ls" produced a real listing (contains our own .bmp artifacts), the listing rendered in the terminal body, and the BMP exported. HONEST SEAM: scancode source still scripted (PS/2 IRQ1 = hw rung); but the COMMAND now hits the real filesystem, not a canned string. No hw writes (Rule 26). expect_exit: 0 license_tier: ORIGINAL
