Security audit (12-angle adversarial workflow) findings on the container→host boundary:
- .env was created world-readable (cp of a 644 .env.example, never chmod'd) exposing the APP_KEY
that decrypts the whole fleet's SSH vault. Now chown clusev + chmod 0600 before any secret write.
- The root updater followed attacker-planted symlinks in the container-writable ./run (update-phase.json,
update.log) → arbitrary root file write. Status writes now go via a temp + rename(2) (never follow a
link); the update transcript moved to the repo root (not the ./run bind mount).
- The generated UPDATE_HMAC_KEY was dead. The app now HMAC-signs the update-request marker
(config/clusev.php update_hmac_key; DeploymentService) and watch.sh verifies it before running a
root update, so a stray/limited write to ./run can't drive one (a full container compromise holds
the key, so this is a bar-raise + integrity check; the standing guarantee is the marker only ever
re-installs the trusted remote's code, never attacker code).
- force_kv/set_kv wrote unescaped values into a sed replacement — a & | or newline in an operator's
domain/email/port could corrupt .env or inject a sed command. Values are now CR/LF-stripped and
sed-escaped, and the HTTP port is validated numeric/in-range.

A dashboard-triggered update that failed on the host left the /update-progress
page spinning to a vague 10-minute timeout — no error was ever shown, because
nothing wrote a failure marker for the page to read. Fix: make failures visible
and prevent the credential-prompt hang class.
- docker/restart-sentinel/watch.sh: run update.sh under `timeout -k 30 1800` with
its output tee'd to run/update.log; on ANY non-zero exit (update.sh or its
exec'd install.sh) — and on the early compose-missing / updater-missing paths —
write {"stage":"error"} to run/update-phase.json via write_update_error().
- update.sh: export GIT_TERMINAL_PROMPT=0 + GIT_HTTP_LOW_SPEED_* and wrap the pull
in `timeout 300`, so a private-repo credential miss fails fast instead of
hanging on a non-interactive prompt.
- DeploymentService::updatePhase(): whitelist the 'error' stage.
- update-progress.blade.php: add an error state (#js-status-error) + showError();
the status-feed poll now stops and shows it on stage=error, marking the active
phase red — instead of looping.
- lang/{en,de}/update.php: error_heading / error_hint / back_button.
- UpdateProgressTest: feed surfaces stage=error; page renders the error branch.

Update-progress phases were a pure time guess, so a fast update sat on "fetch"
then snapped all four green at once. Now the host updater publishes its real
macro-stage and the page tracks it:
- update.sh / install.sh write the current stage (fetch|build|restart|migrate|
done) to run/update-phase.json — best-effort (|| true, never aborts an update).
- new public GET /update-status.json serves that stage (whitelisted) to the page.
- update-progress.blade.php drives the checklist from the feed in REAL order
(fetch → build → restart → migrate), falling back to the time heuristic when no
feed is present, and completes on the feed's 'done' (or the version flip, with a
25s grace fail-safe). Like the 502 fix, the live experience lands one update
after this ships (the page shown DURING an update is the old version's).
Also: Versions changelog series + page are now #[Url]-synced (?series=&page=),
so a series/page is shareable and survives reload / back-button.
Tests: /update-status.json (null / whitelisted / rejected stage), the page polls
the feed, and the changelog deep-link reads ?series=&page=.

Add update.sh (sudo ./update.sh): git pull --ff-only (never discards local
changes), self-update via re-exec if the script itself changed, then hand off
to the idempotent install.sh non-interactively. Sets safe.directory so a
root-run pull works on the clusev-owned tree.
Fix install.sh so a non-interactive re-run (an update) no longer wipes a
configured domain / ACME e-mail: both now default to the existing .env value
when not supplied. First install (empty = bare IP) is unchanged.
README documents 'sudo ./update.sh'; the MOTD shows the update command.
