- fs.rs: node-table VFS (root /dev /tmp /etc). Regular files are
in-memory ramfs; char devices regenerate content on every read so
'cat /dev/rtc' shows the live time. Nodes are stable handles with
tombstone removal; . and .. path resolution.
- /dev devices: mem (raw physical RAM, offset = address), rtc, pci,
version, meminfo, null, zero, console (write prints to screen+serial),
serial. /etc/motd static file.
- shell: ls, cat, hexdump (hexdump -C style), mkdir, touch, rm; echo
gains '>' overwrite and '>>' append redirection (append bug fixed:
first '>' in '>>' was parsed as overwrite)
- boot: fs init + self-test (create/read/write/remove) before the shell
- QEMU verified: file lifecycle, redirection, console/null writes,
mkdir/touch/rm, hexdump /dev/mem and /tmp/x byte-exact

- rtc.rs: read the PC RTC via CMOS ports 0x70/0x71 (UIP wait, BCD/12h
normalization, century sanity-check with 2000+ fallback); boot prints
the wall clock, shell gains 'date'
- pci.rs: legacy config-space access (0xCF8/0xCFC) with full enumeration
of buses 0-255; boot reports device count, shell gains 'pci' (lspci
style listing with class names)
- QEMU q35 verified: Q35 host bridge, stdvga, e1000, ICH9 LPC

- uefi.rs: full EFI_RUNTIME_SERVICES layout with reset_system at index 10
(spec order); EfiResetSystem type + RESET_* constants
- power.rs: stash the runtime-services table pre-EBS; poweroff() calls
ResetSystem(EfiResetShutdown) — still callable after ExitBootServices
because we never call SetVirtualAddressMap, so the pointers keep
working with physical addresses; falls back to the hlt loop
- shell: 'poweroff' and 'exit' shut the machine down (QEMU exits),
'halt' keeps the plain hlt loop

- cmd_mem: correct type grouping — 1|2 loader, 5|6 runtime (new line),
9|10 ACPI, 7 conventional, 11|12 MMIO (previously 6 was mislabeled
LoaderData and 5|10 were called ACPI)
- cmd_mmap: per-region dump using uefi::memory_type_name with
index/type/start/pages/size columns
- cmd_stress <chunks(1-64)> <kb>: allocate chunk Vecs via
try_reserve_exact, report heap+page stats while held and after free;
exercises heap growth past the base region

Architecture:
rs-dos/ (workspace root, was raisernics/)
├── rsnix/ — kernel lib crate (uefi, serial, gop, ps2, interrupts, memory)
├── shell/ — shell lib crate (prompt, commands, line input)
├── rsdos/ — binary crate (efi_main, init, panic handler)
└── rsboot/ — future git submodule
No functional changes — boots to shell prompt identically.
Version auto-pulled from Cargo.toml via env!("CARGO_PKG_VERSION").
