Use the CanoKey for daily authentication on idols-ai and shoukei, with
the existing passwords, passphrases and per-host SSH keys as fallback.
- sudo: pam_u2f with a shared origin (pam://ryan4yin) and a Nix-store
authfile built from myvars.canokeyU2fKeys; the primary key is
registered and touch-to-sudo works on idols-ai.
- SSH: one resident ed25519-sk key (application=ssh:ryan4yin) exported
to ~/.ssh/id_ed25519_sk; GitHub tries it before the per-host key.
- shoukei LUKS: fido2-device=auto with token-timeout=10s. Update
nixos-apple-silicon (linux-asahi 7.2.14), whose initrd adds
thunderbolt_apple and reset_apple_cio so USB-C comes up before unlock.
- GPG: scdaemon disable-ccid so it uses pcscd.
- docs/security-keys.md: setup, PINs, enrollment, backup key and
recovery; deduplicate the FIDO notes left by #515.

* feat(nixpak): pass FIDO2 keys to Firefox, Chromium and Chrome
Assisted-by: DeepSeek Harness (deepseek-flash)
* feat(nixpak): support FIDO2 hotplug via udev-maintained node directory
Replace launch-time hidraw discovery with host udev rules that hard-link
FIDO-tagged hidraw nodes into /dev/fido-hidraw and remove them on unplug.
The sandbox dev-binds that directory and gets static /dev/hidrawN symlinks
into it, so keys plugged in after launch work and no stale node survives a
reused hidraw minor.
Narrow the extra mounts from whole /sys and /run/udev to /sys/class/hidraw,
/run/udev/data and /run/udev/control; the policy suite now forbids the
broad mounts and checks the wrapper and bind follow the fido2 option.
Assisted-by: Claude Code (claude-opus-5-5)
* refactor(nixpak): rewrite FIDO2 bwrap wrapper in Python
The bash argument loop was hard to follow. Python inserts the /dev/hidrawN
symlinks before "--" with a single list splice, and the header now explains
the whole host-udev -> bind -> symlink chain step by step.

* docs(canokey): document phone-only management policy
PCs only use the CanoKey; CanoKey Console management stays in the phone
app and the Admin PIN is never typed on a PC. Record what the config
enforces (sandboxed browsers get no raw USB/CCID, no vendor WebUSB udev
rule) and what it does not (uaccess on the raw USB node, PC/SC access to
the Admin applet, CTAP management from browsers).

Assisted-by: Claude Code (claude-opus-5-5)
* fix(nixpak): create /dev/fido-hidraw from the udev rule
NixOS applies /dev tmpfiles entries only at boot; switch-to-configuration
runs systemd-tmpfiles-resetup with --exclude-prefix=/dev. After a switch
without reboot the directory was missing and every `ln` failed with exit
code 1, so no browser saw the key. The add rule now runs `mkdir -p` first.
Also fix the documented trigger command: `udevadm trigger` defaults to
`change`, which the add-only rule ignores.
Assisted-by: Claude Code (claude-opus-5-5)
* refactor(nixpak): keep tmpfiles as the only creator of /dev/fido-hidraw
The /dev tmpfiles units run before systemd-udevd on every boot, so the
directory always exists before coldplug. The mkdir in the udev rule only
covered the first switch without reboot and duplicated the tmpfiles rule;
drop it and document the one-time `systemd-tmpfiles --prefix` command.

* docs(nixpak): record FIDO2 hardware validation in Firefox and Chrome
After a reboot on ai with the CanoKey present at boot, udev linked only
the FIDO interface and WebAuthn works in Firefox and Chrome. Chromium and
plugging the key in after launch remain pending.

* refactor(shells): use native Home Manager Nushell environment
Replace the Bash login-shell wrapper and hand-maintained Nushell PATH with programs.nushell.loadSessionVariables and home.sessionPath. Launch Nushell directly from Kitty, Ghostty, and Zed, with the macOS config-home override and Ghostty's vendor autoload directory.

* fix(ssh): preserve tuios session marker across SSH
Forward TUIOS_SESSION and accept it on NixOS sshd, so an SSH session opened from inside tuios does not auto-attach a nested remote tuios.

Enable the Nushell login shell through a shared module imported by the server and agent profiles. Desktop profiles continue to use Bash.

Remote interactive shells now stay plain Nushell instead of starting a nested TUIOS when the SSH client is already inside a local TUIOS session. Local TUIOS auto-start is unchanged.

Update nur-ryan4yin to d82be0b. Audit: only the prebuilt packages cua-driver (0.36.0 -> 0.38.0) and computer-use-linux (0.7.20 -> 0.7.36) changed; the NUR modules and trust-related settings did not move. Only the kana and ruby system closures change.

- Add the agent profile (modules/nixos/agent.nix: rootless Podman, linger,
nix-ld) with home/linux/tui.nix as its home role; ruby, kana and
aquamarine use it, so hosts no longer import from hosts/idols-ruby.
- Gate nushell's ~/.secrets source behind modules.shell.secrets.enable,
off on agent hosts.
- Persist the TUI home state on aquamarine's tmpfs root.

Add a dedicated IPython module with startup helpers for JSON, YAML, TOML, and CSV plus a small set of common standard-library imports for interactive use.

A default-node hook selects wivrn.sink/wivrn.source whenever they exist,

`just mihomo-geo` copied geodata into the state dir so a cold start never

myNurPkgs evaluated a second nixpkgs just for four packages. Apply the
NUR repo's own overlay instead, so they come from the host's pkgs.
Darwin's pkgs now gets nixpkgsConfig too: it set nixpkgs.pkgs, which
ignores nixpkgs.config, so only myNurPkgs carried the npm mirror there.

WA-023 warns once nixVersions.stable reaches 2.35; WA-046 fails the build

hardware.amdgpu.opencl.enable also adds clr, whose OpenCL 2.2 libOpenCL.so.1
lands in /run/opengl-driver/lib, first in OpenVINO's RUNPATH, and shadows the

The data dir is the module's own DynamicUser StateDirectory (already

Apply hdparm -B 255 -S 0 whenever a disk appears, which also covers the
re-add after a bridge reset, instead of a boot oneshot plus an hourly

89d7a9bd made systemd-tmpfiles-setup RequiresMountsFor the five nofail

- WA-017: keyd(1) documents `control = layer(control)` etc. as the

microvm.nix's own deploy.rebuild uses; only the in-place sshSwitch is

Each of these overrode a value nothing else set at a higher priority:
- qemu-guest: btrbk, hardwareTools and cloud-init have no competing
definition on the guests.
- mdns: nixpkgs' sunshine module sets avahi.publish.* with mkDefault.
- computer-use: i18n now sets the time zone with mkDefault.
- darwin terminal: the shared ghostty/kitty font sizes are now mkDefault.
- shoukei: sunshine is mkDefault false in remote-desktop.nix, zram's
memoryPercent is mkDefault 50; supportedFilesystems now merges instead
of discarding the fsType entries other modules add.
- youko: nothing enables docker.
- nixpak: pasta.enable and sockets.pipewire are mkDefault in the shared
