The configurator wrote en_US.UTF-8 unconditionally, so a Chinese
install booted into an English system. sys_lang now follows the
installer language, and both zh_CN and en_US locales are always
generated in the target.

The /tmp-fallback case did check-then-create on a fixed /tmp name, a
TOCTOU/symlink race, and the EXIT trap only cleaned $TMPDIR. Create the decoy
atomically with noclobber (O_EXCL) so it refuses to overwrite an existing file
or follow a symlink at that path, and remove it on exit only when this test
created it. The fixed path is required (it is exactly the path the old code
would form), so a random mktemp name cannot replace it. Addresses the Copilot
review on #8198; the wrapper fix is unchanged.
The cached device path was trusted for merely existing, not for being a hiddev node, and fell back to a predictable /tmp path when XDG_RUNTIME_DIR was unset. Validate the cache shape (hiddev char device) and cache only under the user-private runtime dir; asdcontrol already gates non-Apple devices downstream, so this is defense-in-depth in the layer Omarchy owns.
* [Security] Stop the FIDO2 setup staging its authfile at a predictable /tmp path
pamu2fcfg wrote to /tmp/fido2 and the registration was then moved into place
with `sudo mv`. Any other local user can pre-create /tmp/fido2, and rename(2)
does not dereference the final component, so the privileged move installed the
attacker's symlink itself as pam_u2f's global authfile -- a file consulted by
`sufficient` lines in /etc/pam.d/sudo and /etc/pam.d/polkit-1.
The same move also carried the staged file's ownership into /etc, so on every
install to date /etc/fido2/fido2 is owned by the invoking user at mode 0644.
That needs no attacker: anything running as that uid can add its own credential
and satisfy the machine's sudo prompt without root.
Stage under mktemp and hand the bytes to `install` instead, so the authfile is
always a fresh root-owned regular file rather than an inode a non-root user
still controls. Guard the already-registered check with -L, which -f would
otherwise follow, and reject a symlinked /etc/fido2 in the remove path for the
same reason. A migration takes ownership of authfiles left behind by the old
code; it reports a symlink rather than repairing one, since chown would follow
it and removing it would strip sudo from anyone whose only credential is the
token.

* Install the FIDO2 authfile with -T and refuse a non-regular path
`install SRC DEST` without -T treats an existing directory at DEST as a
destination directory: it drops the credential inside as
/etc/fido2/fido2/tmp.XXXX, exits 0, and setup reports a successful registration
while PAM goes on reading a path that is not a file. -T makes that an error.
The already-registered check has the same blind spot from the other side. -f
follows symlinks, so it reads a symlinked authfile as a registration and leaves
it in place, and is false for a directory, so it tries to register over one.
Only a regular file is a pam_u2f authfile; anything else is now refused with the
same advice to remove it and set FIDO2 up again.
The test deleted every staged path that fell outside its scratch directory,
taking the path from the script under test and already resolved through any
symlink -- so a script staging through one would have named a file of the user's
and had it unlinked. It now unlinks only a file its own stub wrote into.
On a machine that already has /etc/fido2/fido2 the staging assertions cannot run
at all, and the file used to pass without exercising one of them. That branch now
asserts what the host state promises instead: a regular authfile still has to be
recognised as a registration and left alone, and anything else has to be refused.

* Replace the FIDO2 authfile inode rather than chowning it in place
Permission is checked at open(2), not at write(2), so a descriptor the
registering user opened on the authfile while it was still theirs stays writable
through chown and chmod alike. pam_u2f resolves /etc/fido2/fido2 to that same
inode, so the repair left the account it authenticates able to append a
credential it controls -- the exact state the migration exists to end, now
recorded as migrated and never revisited.
Installing a fresh root-owned copy and renaming it over the path leaves any such
descriptor writing to a file nothing reads. Credit to #7703, which reached the
same conclusion independently. An interrupted run heals: the staged copy is
root-owned 600 and inert, no marker is written, and the next run replaces it.
A directory or device at the authfile path is no more ours to rewrite than a
symlink is, and chmod 600 on a directory would only make it untraversable, so
both are now reported rather than repaired.
The repair had no test, because it names an absolute path no unprivileged suite
can write. It is exercised through a scratch copy with that one literal
retargeted, rather than by reading the path from the environment: the migration
hands `install` and `mv` root, and an operand the caller can choose is a
privileged write to anywhere. The copy is only as honest as the substitution, so
the test fails if the migration stops naming the path exactly once.
Covered: the no-op on a machine that never registered a key, which must not cost
a password prompt; the repair itself; the new inode; the absence of a staged copy
afterwards; a second account finding it done; and the symlink and non-regular
cases. Each assertion was checked against a mutation that defeats it -- notably a
repair with the right install call, mode, content and cleanup that writes through
the old inode, which only the inode assertion catches.

* Finish hardening FIDO2 authfile installation
* Guard the FIDO2 directory and the stage path the setup writes through
install -d follows a symlink at /etc/fido2 and applies the mode and ownership to whatever it points at, so the credential would be staged and published inside the link target and that directory silently reopened to root:root 755. The leaf guard above it only covered fido2 itself, and this is the same threat omarchy-remove-security-fido2 already names on its side.
mktemp's output is an operand for a privileged tee, chmod, mv and rm. The migration validates it before any of them run; the setup did not, so take only the name it asked for there too.
The suite was guarded on the host's own /etc/fido2/fido2 and exited early when one existed, which meant the staging assertions asserted nothing on exactly the machines that use FIDO2. Drive a retargeted copy the way the migration suite already does, so every branch is a fixture and all of them run everywhere.

* Stop the FIDO2 migration recording a repair it never made
omarchy-migrate writes the per-user completion marker on any zero exit, so the two states this migration cannot repair got one line in the update terminal and were then silenced for good: no login notice, no re-run, the migration recorded as done having repaired nothing. Those are precisely the machines where the authfile may already be under someone else's control, so raise them through omarchy-notification-send as well, where they outlive the scrollback. Delivery is best-effort: a machine with no user bus or no notification server must not abort the migration and take every later one with it.
The early exit had the same shape of problem. It read the authfile unprivileged, and the old setup created /etc/fido2 with `sudo mkdir -p`, which took the union of the caller's umask and sudoers' 0022 — so registering under `umask 077` left the directory mode 0700 with the user-owned authfile still inside. Absence and "cannot look" are the same answer to those tests, and the migration exited 0 and marked itself complete. Ask root whether a registration is actually behind an untraversable directory before reopening it, so an aborted setup that left an empty directory, or one an administrator keeps private, does not have its mode widened and its group and special bits discarded for a repair it does not need. A machine that never set FIDO2 up has no directory here and still reaches exit 0 without a password prompt.
The notification assertion checks argument shape rather than a substring of the command line. The glyph is a private-use codepoint, and losing it shifts every argument left: -g swallows the headline, the body becomes the title, and the message goes out with no description — which a substring match reads as a pass.

* Cover the FIDO2 removal's symlink guard
The -d to -e || -L change is load-bearing for the threat its own comment names — a dangling link at /etc/fido2 that -d reads as absent, left for the next setup to install an authfile through — and it was the one part of this work with no test behind it. Name the directory once so the suite can retarget a copy, the same seam the setup and migration suites use, and assert both halves: the link goes, and the directory it pointed at does not.

* Stop device names from being executed as Hyprland Lua
Hyprland input-device and monitor names come from USB descriptors and
hyprctl output, so they are attacker-influenceable, yet the toggle and
monitor commands interpolated them straight into hyprctl eval and into
generated Lua that Hyprland re-executes on every reload. The input-device
toggle keys are bound with locked = true, so a malicious USB name reached
Lua code execution from the lock screen; a persisted disable made it run
on every start. This closes that class everywhere it appeared.
- The touchpad/touchscreen disable is now the device name in a plain-text
sidecar file, read back by a packaged Lua module on reload, never a
generated Lua file. hyprctl eval Lua-quotes the name and control
characters are rejected outright.
- Dropped the shipped *-disabled.lua templates so nothing seeds a
disabled state to /etc/skel, making the name file the single source of
truth read from a hardcoded ~/.local/state to match the sibling tools.
- The reload loader excludes those two legacy filenames, so a leftover
generated *-disabled.lua on a not-yet-migrated install can never be
sourced as code again; a migration then recovers the device name from
it and deletes it, sanitizing installs that ran the vulnerable version.
- All four monitor scripts (internal, mirror, clamshell, scaling) now
validate an output name against a plain-connector-name pattern before
writing it as Lua, closing the same latent pattern in the siblings.
- paths.lua treats a set-but-empty XDG_STATE_HOME as unset, matching the
bash side so state is never read from the filesystem root.

* Let a failing Lua assertion fail the test
lua discards the status of a chunk read from stdin, so a blown assert printed its traceback and still exited 0: the surrounding `set -euo pipefail` never fired and the following `pass` printed `ok`. Every Lua block in these two files was unenforced, including the assertion that a quoted `hyprctl eval` cannot reach `os.execute` and the negative control that proves the test can detect the injection at all. Passing the chunk as a script argument makes lua report the failure.

* Re-apply a recovered input-device disable to the running session
The package hook reloads Hyprland during `omarchy-update-system-pkgs`, before `omarchy-migrate` runs, and at that reload the generated Lua is already excluded while the name file does not exist yet — so a touchpad or touchscreen the user had switched off comes back on, and stays on until their next login. Reload once more once the name has been recovered, which is the same path a login already takes to read it.

* Pin PATH to trusted dirs when omarchy-dns holds root
A dev link prepends a user-writable checkout bin/ to sudo's secure_path,
so the passwordless `omarchy-dns Cloudflare` sudoers rule lets root
resolve a bare helper (dirname, install, tee, nmcli, ...) out of that
checkout — turning checkout-write access into arbitrary root execution.
Pin PATH to trusted system directories once EUID is 0, leaving the
unprivileged wrapper phase free to locate sudo/pkexec on the caller's
PATH.

* Assert the trusted-PATH pin is gated on root, not merely present
The EUID assertion matched `(( EUID == 0 ))` anywhere in the file, and require_root has carried that exact test since long before the pin existed. Deleting the pin left the assertion passing, so it stood for nothing: a run with the pin neutered reached the behavioural probe with both greps green. Anchor on the unindented guard and require the pin to be the line it opens, which no other construct in the script satisfies.

* Skip the DNS trusted-PATH probe where user namespaces are unavailable
`fail` ends the file, so a sandbox or hardened kernel that refuses unprivileged user namespaces did not just lose the probe — it took the two elevation assertions below it down as well, reporting a product defect where there was only a missing capability. The non-graphical suites are meant to run on any machine and treat a skip as a passing test, the way require_compositor and plugin-add-test.sh already do. Gate the probe on the namespace it needs and say so when it is absent; the static checks above and the elevation checks below run either way.

* Share the git URL check between theme-install and plugin-add
Both commands clone a URL a stranger can choose, and each carried its own copy of the rule that refuses a git option or a `<helper>::<address>` transport helper before cloning. Two copies of a security check drift: the second one arrived four months after the first, and only because someone went looking for it.
The rule now lives in omarchy-git-url-check and the callers ask it. Its absence refuses the URL rather than waving it through, since the callers read a non-zero status as a refusal and a missing command exits 127.

* Refuse a git URL naming a transport Omarchy does not clone from
`<helper>::<address>` is only one of the two ways a URL reaches a remote helper. git also resolves git-remote-<scheme> for `<scheme>://<address>` whenever the scheme is not one it connects itself, so `ext::sh -c id` and `ext://sh -c id` arrive at the same helper while only the first was refused.
That shape cannot be refused outright, because it is also how every legitimate URL arrives, so the scheme is checked against the transports git still connects itself. `git+ssh` and `ssh+git` are on that list: they are spelled like a helper and read as plain ssh, and leaving them off would refuse a URL that clones today. `ext` and `fd` are off it deliberately -- git ships a helper for each, and `ext` runs whatever command the URL carries.

* Guard plugin-add against git transport-helper URLs
omarchy-plugin-add cloned a user-supplied git URL without the
transport-helper guard that omarchy-theme-install already applies
(added in #7884, which did not touch plugin-add). Port that guard
(reject ext::/fd:: and leading-dash forms, keep https/ssh/scp-style
incl. IPv6) and add a regression test. Stock systems are unaffected
(git default protocol.ext.allow=never); this removes the silent
dependency on that default and aligns the two install paths.
* Test the plugin-add guard's leading-dash arm via the gum input path
The prior leading-dash cases only exercised the argv option parser, not
the guard (removing the guard's -* arm left them green). Drive a dash
value through the interactive gum prompt under a pty so the post-input
guard is actually covered; skip cleanly where util-linux script is
unavailable.
The cage wrapper treated the installer session exit code as cage
availability, so an installer abort re-ran the English VT flow. A
gui-started marker now separates the two. Dashboard failure-menu
cases for shell/poweroff now match the localized choice strings.
