A built-in RGB+IR webcam (common on recent ThinkPads, e.g. the T14s AMD
Gen 4) exposes its IR face-unlock sensor as a second, identically-named
"Integrated Camera"; apps that pick it show a dark, 8-bit-greyscale
image. nomarchy.hardware.camera.hideIrSensor disables that node on the
V4L2 PipeWire path (WirePlumber monitor.v4l2.rules) so only the colour
camera is offered, matched by card name (overridable irMatch).
- libcamera is left untouched: an external camera you plug in is never
affected, and surgical internal-only libcamera scoping isn't possible
(its distinguishing props bind after the monitor rule runs).
- Only the PipeWire node is hidden; the kernel /dev/video* stays open,
so Howdy face-unlock still reads the IR sensor directly.
- The installer's hardware-db.sh auto-detects a paired RGB+IR webcam
from /sys/class/video4linux/*/name and bakes the toggle into
system.nix; commented example added to the downstream template.
Validated live on a T14s: collapses the four enumerated "Integrated
Camera" entries to one colour source; the exact shipped regex disables
the IR node (confirmed in the WirePlumber log) and leaves libcamera
intact.

Harden the hardware-enablement broad seed for newer hardware:
- xe vs i915: intel.guc emits the i915 param (i915.enable_guc=3), which the
newer `xe` driver (Lunar Lake / Battlemage / Panther Lake, recent Xe GPUs)
ignores — it enables GuC by default. hardware-db.sh now reads the in-use
GPU driver (lspci -k) and writes `intel.guc = false` on xe hardware, so the
toggle isn't a misleading no-op there.
- NPU detection by PCI accelerator class [1200] (+ keywords), attributing the
vendor, instead of a fixed device-ID list — so new NPUs (e.g. Panther Lake)
are caught without a code change. Known IDs kept as a fallback/reference.
- Kernel awareness: a nomarchy.hardware.latestKernel escape hatch
(linuxPackages_latest) for very-new hardware whose drivers only just landed,
and a build-time warning when npu.enable predates the shipped kernel
(amdxdna needs 6.14+, intel_vpu wants recent). Downstream default is 6.18,
which already carries amd-pstate + amdxdna; the reference host pins latest.
- VM test (checks.hardware-toggles, pkgs.testers.runNixOSTest): boots a
minimal VM with the toggles on and asserts the config landed — amd_pstate
+ i915.enable_guc in /proc/cmdline, fprintd.service present, pam_fprintd in
/etc/pam.d/sudo. Passing. (Hardware behaviour still needs bare metal.)
Docs: README + template note latestKernel; ROADMAP records the hardening.

The nixos-hardware "common-*" profiles the installer selects cover the
basics (microcode, the Intel/AMD VA-API media stack, weekly fstrim), and
power.nix adds thermald + power-profiles-daemon. This adds the gap above
them, generically and detected at install time.
New modules/nixos/hardware.nix exposes a vendor-keyed nomarchy.hardware.*
surface — broadly-beneficial bits default ON when the vendor is detected
(opt-out), heavy/experimental bits behind opt-in toggles:
- intel.enable -> GuC/HuC (i915.enable_guc=3); intel.computeRuntime
(opt-in: intel-compute-runtime + vpl-gpu-rt)
- amd.enable -> amd_pstate=active + radeonsi VA-API env; amd.rocm.enable
+ amd.rocm.gfxOverride (opt-in: ROCm HIP/OpenCL)
- fingerprint.enable -> fprintd; fingerprint.pam (opt-in: login + sudo)
- npu.enable (opt-in/experimental) -> the in-kernel driver
(amdxdna/intel_vpu) keyed by vendor; userspace runtime is BYO
hardware-db.sh now detects Intel/AMD, a fingerprint reader (libfprint USB
vendor IDs) and an NPU (Intel VPU / AMD XDNA PCI IDs), emitting NOMARCHY
lines the installer bakes into system.nix — safe defaults active, opt-ins
commented. Audited against the commons to avoid double-setting.
Verified: flake check green; a toggles-on build has amd_pstate=active +
i915.enable_guc=3 in kernel-params and ships fprintd.service; detection
runs correctly on the (AMD Ryzen-AI) dev machine. On-hardware verification
of the AMD/NPU/Intel-compute runtime bits is still pending.
Docs: template commented examples, README option table, ROADMAP status.

Found by running the unattended install in an offline QEMU VM:
- compgen is missing from nixpkgs' non-interactive bash (the package
shebang) — replaced with plain glob tests in hardware-db and prewipe
- disko's eval resolves <nixpkgs> via NIX_PATH (a dead channel on the
ISO) and tried channels.nixos.org — export NIX_PATH to the pinned
nixpkgs source and point the flake registry at an empty baked file
- lock nomarchy by path (the source the ISO carries) instead of
git+https: git inputs clone even when narHash is known, which kills
offline installs; `original` keeps the forge URL so a later
`nix flake update` re-resolves normally. Works from dirty-tree ISOs too.

Ported from the previous iteration's installer (3bdfc35), adapted to the
mkFlake world. gum TUI: disk pick, optional LUKS2, user/hostname/timezone,
DMI → nixos-hardware autodetection (hardware-db.sh). disko partitions
GPT + 1 GiB ESP + BTRFS subvolumes; the generated machine flake lands at
~user/.nomarchy (one mkFlake call, /etc/nixos symlinks to it) and
nixos-install makes it bootable (UEFI/systemd-boot, v1 single disk).
Offline by construction: the target flake.lock is composed from the rev
the ISO was built from (compose-lock.py), `nix flake archive` seeds the
target store, and the ISO pre-builds the template system + desktop.
First boot lands themed: the HM generation is pre-activated in chroot.
mkFlake grows two things for this: hardwareProfile now also takes a list
(autodetection emits several common-* modules), and installed systems get
the standalone home-manager CLI from the pinned input. Unattended mode
(NOMARCHY_UNATTENDED=1 + env) documented in docs/TESTING.md §4.
