Confirmed-security quick-wins from a full re-audit (6-agent subsystem fan-out,
Codex-reviewed). Each item ships with a regression test proven to fail pre-fix.
- files: gate file CONTENT reads (download / edit / FileEditor::load) behind the
`operate` ability so a read-only viewer keeps LISTING/browse access but can no
longer pull file bytes over the server credential (root -> /etc/shadow, keys,
.env). Hide the download/edit/delete controls from viewers in the blade, and
basename() Files::open() for parity with the other path builders.
- fail2ban: reject a leading dash/dot in validJail(). A jail name like "-h" or
"--help" was parsed by fail2ban-client as an OPTION (argument-injection) rather
than a positional jail; internal dashes ("nginx-http-auth") still pass.
- bruteforce: release the atomically-claimed ban-audit dedup slot when the
AuditEvent write throws, so a transient DB failure no longer suppresses the
auth.ip_banned audit for the whole 60s window (the ban itself is unaffected).
- update path: verify_update_request now FAILS CLOSED when UPDATE_HMAC_KEY is
unset (was fail-open -> any ./run marker could drive a root update). Pin the
self-update `git pull` to the recorded CLUSEV_BUILD_BRANCH and refuse a diverged
checkout, so a `git checkout` in the tree cannot redirect the next root update.
- wireguard: normalise the DNS input to a single comma list and QUOTE the WG_DNS
assignment in wg.env; an unquoted space previously split the assignment and
broke the next `. "$WG_ENV"`.
13 new regression tests. 614 tests, Pint, shellcheck, Codex review all green.

Opening a binary / non-UTF-8 file in the file manager threw "undefined is not
valid JSON". The editor bound the raw file bytes to its public $content
property; Livewire JSON-encodes the component snapshot, and invalid UTF-8 makes
PHP's json_encode return false, so the client received an empty response and
JSON.parse("undefined") failed (the trace in mergeNewSnapshot/deepClone).
Fixed at both layers: FleetService::readFile blanks the content when it detects
binary/non-UTF-8 (returns the binary flag instead), and FileEditor::load only
binds content for non-binary, non-oversize files. Binary/oversize files show
their existing notice; the snapshot is always valid UTF-8.
Tests: load blanks binary content (keeps the snapshot valid) and keeps valid
text content. 374 pass, Pint clean.

Opening an image now renders it (SFTP base64 data-URI, 5 MB cap, save disabled for
images) instead of the text editor. Recovery-codes modal buttons realigned + the
close button relabeled 'Schließen' (it only closes). All modal textareas resize-none.

Full feedback round — all browser-verified (R12: 7 routes 200, zero console errors)
and functionally tested live against the target host.
- Metrics are real AND honest: poller now stores cpu/mem/DISK/LOAD history (all
four sparklines real, not synthetic); KPIs show absolute context (Memory
"1,9 / 7,8 GB", Disk "13 / 80 GB", Load "4 Kerne"); tiles are status-coloured
and Load is rated against core count (so "yellow" actually means load≈0.7-1.0×
cores), not a fixed warning tint.
- File manager is functional: Hochladen (Livewire upload -> SFTP put), Download
(SFTP get -> streamed), and view/edit (new FileEditor modal: SFTP get, binary/
size guards, SFTP put on save + audit). File names + Bearbeiten open the editor.
- Settings redesigned (/frontend-design): account identity header + section nav
(Profil / Sicherheit) instead of flat stacked panels.
- Routes are English (R13): /einstellungen -> /settings; rule added to rules.md +
CLAUDE.md. Dummy data removed: the topbar "Flotte online / Uptime 42d" + dead
bell button are gone, replaced by a real "<online>/<total> online" pill.
New: app/Livewire/Modals/FileEditor + view; FleetService get/read/write/upload +
Sftp putFromFile/size.
