The panel domain is editable on the System page again — safely this time. It is
stored in the DB (Setting `panel_domain`, overriding install-time APP_DOMAIN) and
APPLIED ON RESTART, never mid-session: a snapshot file (storage/framework/active-domain)
is frozen at container start by the entrypoint (`clusev:snapshot-domain`), so saving a
new domain only takes effect after `docker compose ... restart`.
How it works
- DeploymentService: pending (configuredDomain, DB) vs active (domain(), snapshot file);
setDomain() persists; restartPending() drives the UI notice. Snapshot reads the DB
DIRECTLY (cache-independent) and retries until the settings table is readable; if it
never is, it freezes the env fallback so the active domain is always a FIXED value
(never a live one that could shift after startup).
- AppServiceProvider: derives app.url from the active domain at boot; pins server->Reverb
publishing to the internal reverb:8080 (domain/cert-independent).
- Caddy: on-demand TLS gated by /_caddy/ask (issues a cert only for the configured
domain); HTTP always served for bare-IP recovery; /app,/apps forced to HTTPS for any
hostname (plaintext only on a bare IP).
- Reverb client endpoint is derived from the live request and rides the same front door
(/app tunnel — Caddy in prod, nginx in dev), so realtime follows a domain change with
no JS rebuild and no stale .env value.
- System page: domain form + R5 confirm + "restart required" notice with the exact
command; DE/EN strings (R16).
Anti-lockout / security
- session.secure + the HTTPS redirect follow the real request scheme; bare-IP HTTP is
always a recovery path. trustProxies('*') only in production (dev can't be tricked into
faking HTTPS via X-Forwarded-*). When a domain is active only that domain (HTTPS) and
the literal server IP (HTTP) serve the panel; any other/stale host is refused (404),
and IP-recovery redirects stay on the IP.
Bump 0.3.0 -> 0.4.0; CHANGELOG. Follow-up tracked: make the public `metrics` broadcast
channel private (wire broadcasting auth).
Verified: Pint clean; npm build; Caddyfile validates; R12 all routes 200 + 0 console
errors; Echo connects via the unified /app tunnel; domain set/clear + restart-gating +
/_caddy/ask (200 active / 403 other) + host-enforcement matrix all confirmed in dev;
Codex review iterated to no actionable in-scope findings; 14-agent adversarial
lockout/security review (real trustProxies finding fixed).
