ICU takes the zone name from the /etc/localtime symlink target path. A bind
mount turns it into a plain file, which keeps the TZif data but loses the
path, so the only identifier left is the ambiguous "CST" abbreviation that
ICU reads from the file and maps to America/Chicago.
Export TZ from time.timeZone and pass TZ/TZDIR through the nixpak env
allowlist.

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): 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.

* 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).

* 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.

* 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.

Move standalone repository docs from the root into docs/ and add a documentation index that links the moved docs and the code-local runbooks.
Update Markdown links, source comments, and the root entry points to the new locations. Keep README.md and AGENTS.md at the root as required entry points.

* refactor(nixpak): split policy checks into per-app suites
Make hardening/tests/policy.nix a small loader that auto-discovers one suite per app under hardening/tests/policy. Shared checks live in policy-lib.nix and common expectations are generated by mkAppPolicy; app files only declare differences and special cases. The loader also discovers wrappers from hardening/nixpaks and fails when wrapper/suite inventory or check names diverge.
Assisted-by: DeepSeek Harness (deepseek-flash)
* fix(nixpak): reject duplicate per-app policy checks
mkAppPolicy merges generated and custom checks, so an extraChecks key could silently override a standard assertion. Fail explicitly when a per-app check name is defined twice.

Switch to the native deb package from nixpkgs-patched (#560225), remove the AppImage/FHS bwrap layer, and enable native Wayland while keeping the X11 fallback.
Keep only WeChat state under one app-scoped HOME and bind the host Documents and Downloads directories like the other desktop apps. User-selected files also go through the XDG FileChooser portal. Remove the launcher, activation script, and compatibility symlinks.
