Treat the picker-only (none) row as an empty XKB variant at the shared input boundary and again in the template patcher. Guard the real downstream output and console keymap, and carry the sentinel through the offline installer VM.
Verified: V0 full flake evaluation plus shell/Python/Nix/diff checks; V1 installer-keyboard, installer-safety, and template-SoT builds; V2 full KVM offline LUKS+swap install and themed first boot. No V3 required.
When hardwareProfile includes common-gpu-nvidia, emit a comment-only
plain NixOS block (PRIME / powerManagement / open-module) in the
installer region of system.nix — same pattern as ROCm/NPU opt-ins.
HARDWARE.md §6 product direction marked shipped. Close#59.
Verified: V0 (patch-template smoke + negative + bash -n).
Make the downstream template the single source of truth for machine
flakes: nomarchy-install copies flake/system/home/theme-state and
patch-template.py only fills hostname, user, keyboard, detected
hardware, snapper, resume, and password. Install and flake-init users
now share the same commented opt-ins and starter home.packages.

HARDWARE.md from prior work if uncommitted.
