SOPS_AGE_KEY_FILE was set in hosts/nixos/home.nix sessionVariables with a
literal ~ that Home Manager injects as-is into the environment. In bash,
tilde expansion does not happen inside double-quoted variable references, so
DEFAULT_SOPS_AGE_KEY_FILE resolved to ~/... literally and the -s file-existence
check in ensure_admin_decrypt_key silently failed. The script then generated
a brand-new age key (to ~/... relative to the repo root) while the real admin
key at ~/.config/sops/age/keys.txt went untouched -- making it appear the key
was lost when it was actually still intact.
Fix the home.nix root cause by using config.home.homeDirectory so the path
is fully resolved. Add tilde expansion in ensure_admin_decrypt_key as a
belt-and-suspenders guard for any caller whose environment has the same issue.
Also replace the auto-generate-a-new-key fallback with a hard failure: auto-
generating a new admin key is never useful (it cannot decrypt existing secrets)
and created serious confusion about whether the original key was lost.

Wires everything staged so far into a real flake target:
- modules/platforms/baremetal.nix (new): the bare-metal platform module,
composed from a real nixos-generate-config run on the actual gui-host
hardware (AMD CPU, ahci/xhci/usb storage -- modules/hardware-configuration/baremetal.nix).
Enables hardware.enableRedistributableFirmware (real wifi/GPU/microcode
firmware VMs never needed), amdgpu as the Xorg video driver plus
hardware.graphics for Mesa OpenGL/Vulkan, and imports the ZFS RAID0 disko
layout + modules/services/zfs/enable-service.nix for root-on-ZFS boot
support.
- flake.nix: new baremetal-gui target, reusing hosts/nixos/host.nix (same
identity already shared across linode/proxmox/lxc-gui).
- hosts/nixos/host.nix: added networking.hostId, required now that a ZFS
root pool is in the picture.
- variables.nix: guiRootDisk1/guiRootDisk2 filled in (/dev/sda, /dev/sdb --
only used transiently at disko-format time, same as modules/disko/proxmox.nix's
own plain device path). wifiPassword removed.
- modules/networking/wifi.nix: reworked to pull the wifi password from a
new sops secret (secrets/gui.yaml, wifi-password) instead of a plaintext
variable -- NetworkManager's ensureProfiles renders `psk = "$WIFI_PASSWORD"`
literally (nixpkgs' own documented pattern for this) and envsubst-expands
it from a sops-rendered EnvironmentFile at activation, so the real value
never touches the Nix store, only /run.
- .sops.yaml: new secrets/gui\.yaml rule, admin + the currently-registered
lxc-gui recipient (the only gui variant with a provisioned host key so
far -- whichever variant is actually deployed next still needs
scripts/secrets/sync-host-keys.sh run for its own recipient).
- README.md/CLAUDE.md: documented the new platform/target and its module
layout, per this repo's own drift-prevention note.
Verified end-to-end: nix eval of every existing target (nothing broke),
a temporary real nixosSystem build against the actual disko.nixosModules.disko
confirming the generated zpool create has no mirror/raidz keyword (genuine
stripe), and a temporary test SSID confirming the sops secret/template/
ensureProfiles chain renders correctly before reverting to blank/real values.
Full scripts/codex-maintenance.sh (secret-grep, fmt, statix, full-fallback
eval of every host/package) passes clean.
Adds modules/networking/wifi.nix using NetworkManager's ensureProfiles
mechanism so the gui host associates to a known SSID on first boot with
no manual nmtui step. Credentials are placeholders in variables.nix
(wifiSsid/wifiPassword, both empty) to be filled in once the bare-metal
hardware profile is wired up — the module is a no-op until then.
Adds nested vars.nfsShares (subpath + mountpoint per dataset, previously
duplicated independently across server.nix's NFS exports, mount-data.nix's
client mounts, docker.nix's tmpfiles rules, traefik's log rotation path,
and hosts/server/host.nix's beszel config), vars.ports (every literal port
in modules/ and hosts/, kept as separate entries per service even where
numbers coincide so changing one can't silently change another), plus
vars.proxmoxImageSize, vars.nixCacheGcMaxAge, vars.traefikLogRotate, and
raspberryPiHost/raspiNfsPath/raspiMountpoint for the Pi's own NFS export.
Also fixes docker.nix/minimal.nix/gui.nix hardcoding the literal "nixos"
username instead of the existing vars.primaryUser, found during the sweep.
system.stateVersion is deliberately left untouched everywhere -- per
NixOS's own docs that value must stay fixed from first install, not
follow any shared variable.

Zero W20 (repeated attribute keys), W10 (empty { ... }: variadic
pattern, use _: instead), and W04 (a = x.a instead of inherit)
warnings remain anywhere in the tree, and nixpkgs-fmt --check is
clean on all 46 .nix files.
Repeated-key merges go as deep as statix actually flags per file
(e.g. boot.loader.* nested under boot.loader = { ... } once the
outer boot.* merge exposed it as its own repeat) — every merge is a
pure attribute-path restructuring with no value changes, verified by
comparing config.system.build.toplevel.drvPath before/after for a
representative host per changed module plus a full 19-host + 4-package
eval sweep.
One indentation slip caught and fixed during this pass: nesting
modules/installer/common.nix's environment.etc."auto-install.sh".text
under an environment = { ... } block initially normalized the
script's shebang/set line indentation, which actually changes the
rendered file (Nix's '' string dedent treats it as real content, not
cosmetic whitespace) — reproduced the original's exact indentation
and reverified the rendered script is byte-identical to before.
modules/services/zfs/auto-mount-volumes.nix picked up formatting too;
worth noting it isn't imported by anything in this flake at all.

Pulls the beszel hub / PVE / PBS ports, the docker-compose host's LAN
name, and the remote-builder client SSH keys out of scattered inline
literals across modules/hosts and into variables.nix as the single
source of truth, matching the existing pattern for other cross-host
references (nixCacheHost, nfsServerHost).

One file (variables.nix) holding every value that was previously
hardcoded and repeated across modules: LAN domain/CIDR, home/tailnet
domains, cross-host references (nix-cache substituter hostname, NFS
server hostname, remote-builder user), PXE/PBS IPs, timezone, and the
primary username.
Wired in via flake.nix's specialArgs (and home-manager's
extraSpecialArgs for the two home.nix files), so any module picks it
up by just adding `vars` to its function arguments — no explicit
import needed. Two hosts (nix-cache, server) now derive their own
networking.hostName from the same variable other hosts use to reach
them, so there's exactly one place to change either identifier.
Purely mechanical: every substituted value matches what was already
there, confirmed by identical toplevel .drv paths for all 17 targets
before and after.

Generates all nixosConfigurations from mkTarget(platform, buildType,
hostPath) instead of hand-written per-host blocks, so adding a new
platform or build type is a one-line addition. Per-machine identity
(hostname, hostId, secrets, stateVersion) moves into hosts/<name>/host.nix;
platform-specific config (hardware, boot, networking) into
modules/platforms/*.nix; build-type config (minimal/server/docker/gui/
nix-cache/pxe-boot) into modules/build-types/*.nix.
Old flat targets (nixos, docker, server, nix-cache, nix-minimal, pxe-boot)
are replaced by the 17-target <platform>-<buildtype> matrix; each new
target was verified to evaluate before its old counterpart was removed.
CI workflows and docs/aliases now discover hosts dynamically via
nixosConfigurations attrNames and /etc/flake-target instead of hardcoded
lists, so they can't drift from flake.nix again.
