Deleting the whole ancestor walk from validate_trusted_directory and checking
only the immediate parent left the suite green, so the invariant the design
rests on had no coverage: a writable ancestor lets an attacker swap a validated
directory out from under the leaf. Reject a run whose destination grandparent
is world-writable while the destination itself is pristine.
The harness also rewrites the root script's fixed /usr/share paths by string
substitution. A drifted string silently no-ops that rewrite and would point the
simulation at the real system tree, so assert each substitution landed. Assert
the scratch directory exists too: a failed mktemp left it empty and the suite
carried on building paths from it.

Every check inside the root shell is a bare [[ ]] or (( )) assertion that
aborts under set -e, so a refusal exited with status 1 and no output at all.
The floating-terminal wrapper then printed its green "Done!" for any status
but 130, so a failed boot-theme change read as a success.
The refusal a working machine actually hits is omarchy dev link, which points
OMARCHY_PATH at a checkout the desktop user owns. Name that case outright and
point at omarchy dev unlink; report every other rejection through an ERR trap
that names what failed validation.

Hermes now keeps chat queries interactive and literal to TUI control syntax, so launch it directly and let its own session flow replace the local one-shot, usage-file, and resume bridge.
Gate installation on the capability added with native interactive queries, preserve unowned mise environments, and keep the unprompted launch path unchanged.

Clear inherited session-source tags for Omarchy's local one-shot process so Hermes records the launch directory before the exact session is resumed in the TUI.

Bind option-looking prompts to one-shot mode, require a successful completed usage report before resuming, replay the prompt after first-run setup, and reject Hermes runtimes that lack the session-report capability.

Keep the one-shot session on Hermes' native CLI source so it records the launch directory before the exact session is resumed in the TUI.

Hermes TUI startup queries execute slash, shell, interpolation, and multiline syntax before reaching the model. Run the prompt through literal one-shot mode, read its exact session ID from a private usage report, and resume that session in the TUI so arbitrary prompt text stays data while the conversation remains interactive.

Hermes oneshot deliberately exits after answering, which closes the agent terminal. Seed the TUI chat session instead, keep inherited flags after the subcommand for older Hermes parsers, and bind the query as one argument so dash-prefixed prompts remain data.

AGENTS.md asks for unquoted variables inside `[[ ]]`, with quotes reserved for string literals being compared. The three conditions added here quoted them.

Neither half of the validation was covered. Dropping `&& -c $cached` from the wrapper left the whole file green: all three poison values fail on the pathname prefix, so none of them ever reached the character-device test. A path that matches the hiddev glob but is not a device now covers it, and it is the real case rather than a synthetic one -- the display replugs, the interface renumbers, and the cached node is gone. It is added only when the host has no such node, so a machine with the display attached cannot fail there spuriously.
The no-XDG_RUNTIME_DIR assertion had the same problem for the opposite reason: its decoy held a path the validation rejects on its own, so restoring the `${XDG_RUNTIME_DIR:-/tmp}` fallback left it passing. It asserts on the open now instead of on the contents -- a FIFO with no writer blocks whoever opens it, so a wrapper that consults the path hangs and one that ignores it exits. mkfifo is atomic and fails outright if the path is taken, so it still neither overwrites a file nor follows a symlink at the fixed path.
Clearing created_tmp_cache as soon as the decoy is removed keeps this run's EXIT trap from deleting a concurrent run's decoy at the same fixed path, which would have let that run pass against the old code.

The scheme check ran after the interactive branch, which had already handed the URL to curl: a refused `file://` or `ftp://` URL was dereferenced first, the whole string went out to Google's favicon endpoint in a `domain=` query, and a fetch that happened to succeed left an orphan icon and a rebuilt icon cache behind. Validating immediately after normalization puts the refusal ahead of every dereference in both branches.
A leading space also kept the URL out of the scheme test entirely. `normalize_webapp_url` saw no scheme, prefixed it, and ` file:///etc/passwd` became `https:// file:///etc/passwd`, which passes `^https?://`. The desktop `Exec` field is unquoted, so it splits back into two arguments, and `omarchy-launch-webapp` forwards everything after the first to the browser, where a bare argument is another URL to open. Refusing whitespace closes that without touching desktop-entry escaping.
Scheme comparison is case-insensitive because schemes are: `HTTPS://example.com` installed before this check existed and has no reason to stop.

The username prompt already refuses the service accounts a desktop user must not claim, cups and lp among them. A user who took cups-browsed would get a primary group of that name, and the CUPS authorization written here puts that group in SystemGroup, handing that desktop user the passwordless administration the rest of this change removes.

cupsd compares directive names with _cups_strcasecmp, so a hand-edited "systemgroup sys root wheel" is live configuration, but matching $1 against the canonical spelling skipped it and appended a second directive at the end of the file. parse_groups accumulates the groups of every SystemGroup directive it reads rather than replacing them, so both lines took effect and wheel kept the passwordless administration this is meant to remove, with the migration reporting success.

A bracket range is collated, not ASCII, so `[a-z]` admits `é` under
en_US.UTF-8 and refuses it under C: the same theme URL installed on one
desktop and was refused on the next, and the manual's stated set was only
true in the C locale. Pinning the comparison makes the written set the
shipped one everywhere.
git reads a URL as scp-style when a colon appears before any slash, so the
path after it need not contain one. Requiring a slash left the prefix on
`git@host:omarchy-blue-theme.git` and derived the name
`git@host:omarchy-blue`, which the allowlist then refuses -- a repo that
clones fine could no longer be installed at all.

The migration recomputed whether cups-browsed was active at the start of every run, after an earlier run may already have stopped it. A run interrupted between that stop and the completion marker left the service down, and the retry that followed read it as inactive, skipped the restart, and wrote the marker anyway: printer discovery stayed off until the next reboot with no migration left to bring it back. Keying the restart to whether the unit is enabled survives the interruption, and reports not-enabled for a unit the user masked or disabled, which restarting would fail on and abort the migration short of its marker.

GNU sed's N auto-prints the pattern space and exits at end of input, so the
`:a;N;$!ba` slurp skipped every following s/// for a value with no newline in
it. That is every value except the injection attempt the escaping exists to
stop, so the Exec quoting's own backslashes were written to the file unescaped
and GLib refused to load the entry.

The slash guard was the only thing keeping a name out of the directory structure, and nothing tested it: deleting it left the suite green, because creating the launcher directly in the applications directory already makes the redirect fail on its own, with a raw bash error instead of the message. The assertion is on the message now, alongside the traversal case the guard actually closes -- on quattro a name of `../../../../escaped` writes its launcher clean outside the applications directory.
The interactive prompt read the name, fetched the favicon, wrote it and updated the icon cache before the name was ever checked, so a URL typed into the Name field left an icon behind on every attempt. Validating as soon as the name is read covers both paths from one place.
Removing by name also scanned unconditionally, so a machine with no applications directory printed a find error where omarchy-remove-gaming-xbox-cloud does not hide stderr.

Each of these is a Text rendering external data with no textFormat, written in
a form that passed silently. None exists in this tree, so they were holes in
the guard rather than live exposures — but a guard is only worth what it
catches, and every one of them is a single line someone could plausibly write.
Text /* why */ { strip_noise knew // and not /* */, so a block
comment between the type name and its brace hid
the element from every rule at once
QQ.Text { ... } a namespaced import made the name compare unequal
to `Text`, and the element was skipped outright
visible: textFormatEnabled textFormat was matched as a substring, so a
lookalike property exempted the whole block
component Info: a component root with its Text on the next line;
Text { the one-line form was covered and this was not
an unreadable subdirectory rglob() swallows a directory it cannot enter, so
a locked subtree scanned as though it were empty
The scan moves out of the heredoc into qml-text-format-scan.py, taking its root
as an argument, because nothing could run it over anything but the real tree —
and a scanner whose only input always passes cannot be shown to fail. The test
now runs it over nineteen fixtures, one per form above and one per form the
scan already handled, so a later edit that loosens it fails here instead of
going unnoticed until something renders a remote image.
Two limits stay open and are written down in the module docstring rather than
papered over: text assigned from elsewhere (a Binding element, PropertyChanges,
an onCompleted assignment, a property alias onto a child) is invisible to a
scanner that reads each element's own declaration, and a regex literal holding
a brace throws off the brace depth. Neither shape exists in this tree and both
need a QML parser, not another regex.

The card binds the body Text to styledBody, which rewrites newlines to <br/>
*after* sanitizeBody has run. That rewrite inserts tag syntax into text the
stripper deliberately kept: a kept tag may hold a `<` of its own, and `<x`,
newline, `<img src="http://host/x.png">` is one tag named `x` to both the
stripper and Qt, so it survives whole — until the rewrite splits it into
`<x<br/>` and a live image tag the input never contained.
Measured against Qt 6.11.2 with an offscreen StyledText and a local HTTP
server: that body issues the GET after this branch's sanitizer and issues
nothing before it, because the one-pass /<img[^>]*>/gi it replaces deleted the
inner substring outright. The whole-tag bound is still the right trade — it is
what stops the stripper manufacturing tags — but it only holds if nothing edits
the string afterwards.
So move the rewrite into NotificationLogic, next to the reasoning it depends
on, and strip again after it. What Qt parses is then what was checked last. The
tests assert on styledBody for the same reason, since sanitizeBody's output is
no longer the string that reaches the renderer, and a regex assertion pins the
card's binding because no JavaScript assertion can see a QML property.
The section had grown a paragraph per review round, each one explaining why the last was right, until one offer took a third of the file. Most of it was reassurance about what the command refuses rather than anything an agent has to do, and the command enforces that itself whatever the prose says.
What is left is the instruction: offer it and never run it unprompted, say how to lift it, which of the two names to pass and why the binary is the better one, quote it because the name is the crashed program's to choose, and name the interpreter collision before muting python or node on someone's behalf. Fifty-four lines to thirty-two, with nothing dropped that changes what the agent does.
