# WireGuard dashboard — Phase 5 (first-time setup from the UI) Implementation Plan
> **For agentic workers:** REQUIRED SUB-SKILL: Use superpowers:subagent-driven-development. Steps use `- [ ]` checkboxes.
**Goal:** Set WireGuard up **entirely from the dashboard** — the `/wireguard` "not configured" state becomes a setup form (subnet / port / endpoint / first-peer name); on submit the host creates the tunnel + first peer and the dashboard shows the first peer's config + QR once. Closes the last gap so WireGuard is 100% dashboard-managed (the user's explicit requirement). The SSH `clusev wg setup` stays as an alternative.
**Architecture:** Reuses the P3 write-bridge. New host action `setup` (non-interactive) in `serve-request`: it refuses to clobber an existing config, re-validates every arg host-side, runs the host **collision check**, generates server keys, writes `wg0.conf`+`wg.env` (0600), enables `wg-quick@wg0`, creates the first peer, and returns its client config. **It does NOT enable the gate** (the panel stays publicly reachable until the operator toggles the gate on — no lock-out). `WgBridge` gains a validated `setup` action; the component gets a `setupWg()` + a setup form in the unconfigured branch; the result (first peer config + QR) reuses the P3 show-once modal.
**Tech Stack:** bash (host), Laravel 13 + Livewire 3, Tailwind tokens, Pint, shellcheck. Spec: `docs/superpowers/specs/2026-06-20-wireguard-dashboard-sp2-design.md` §5 (first-time setup, previously deferred — now in scope).
**Run tooling (R8):** as prior phases. Commit on `feat/v1-foundation`; push only at release.
**Security:** the four args (subnet/port/endpoint/name) are validated app-side (`WgBridge`) AND re-validated host-side (strict patterns + `valid_name` + the CIDR/range checks + `subnet_collides`). They flow into heredocs (config files) — the strict charsets exclude newlines so no extra config line can be injected. Server private key written 0600 under the `umask 077` already set in `serve-request`. No gate change.

## Task 1: host non-interactive setup
**Files:** Modify `docker/wg/clusev-wg.sh`
- [ ] **Step 1: Add `_setup_noninteractive` core** (place near `cmd_setup` / the other cores). It mirrors `cmd_setup`'s file writes but takes args, re-validates, refuses to clobber, does NOT gate, and prints the first peer's config to stdout:
```bash
# Non-interactive setup for the dashboard write-bridge. Args are re-validated here (defence in
# depth). Refuses to clobber an existing wg0.conf. Does NOT enable the gate. On success prints the
# first peer's client config to stdout (for the show-once modal). Errors to stderr, non-zero on fail.
_setup_noninteractive() {
local subnet="$1" server_ip="$2" port="$3" endpoint="$4" peer1="$5"
have wg || { echo "wireguard-tools fehlt" >&2; return 1; }
[ -f "$WG_CONF" ] && { echo "WireGuard ist bereits eingerichtet" >&2; return 1; }
printf '%s' "$subnet" | grep -qE '^[0-9]{1,3}(\.[0-9]{1,3}){3}/[0-9]{1,2}$' || { echo "Ungueltiges Subnetz" >&2; return 1; }
case "$server_ip" in ''|*[!0-9.]*) echo "Ungueltige Server-IP" >&2; return 1 ;; esac
case "$port" in ''|*[!0-9]*) echo "Ungueltiger Port" >&2; return 1 ;; esac
[ "$port" -ge 1 ] && [ "$port" -le 65535 ] || { echo "Port ausserhalb 1-65535" >&2; return 1; }
case "$endpoint" in ''|*[!A-Za-z0-9.:_-]*) echo "Ungueltiger Endpoint" >&2; return 1 ;; esac
valid_name "$peer1" || { echo "Ungueltiger Peer-Name" >&2; return 1; }
subnet_collides "$subnet" && { echo "Subnetz kollidiert mit einer bestehenden Route/Adresse" >&2; return 1; }
umask 077; mkdir -p "$WG_DIR" "$STATE_DIR"
local srv_priv srv_pub prefix
srv_priv="$(wg genkey)"; srv_pub="$(printf '%s' "$srv_priv" | wg pubkey)"
prefix="${subnet##*/}"
cat > "$WG_CONF" <<EOF
[Interface]
Address = ${server_ip}/${prefix}
ListenPort = ${port}
PrivateKey = ${srv_priv}
EOF
chmod 600 "$WG_CONF"
cat > "$WG_ENV" <<EOF
WG_SUBNET=${subnet}
WG_SERVER_IP=${server_ip}
WG_PORT=${port}
WG_ENDPOINT=${endpoint}
WG_SERVER_PUBKEY=${srv_pub}
EOF
chmod 600 "$WG_ENV"
systemctl enable --now "wg-quick@${WG_IF}" || { echo "wg-quick@${WG_IF} konnte nicht gestartet werden" >&2; return 1; }
_peer_add "$peer1"
}
```
- [ ] **Step 2: Add the `setup)` branch to `cmd_serve_request`.** In the `case "$action"` switch (it already extracts `name`, `endpoint`, `port`, `subnet`), add before the `*)` arm:
```bash
setup)
local sip ep pn
sip="$(subnet_first_ip "$subnet" 2>/dev/null || true)" # server IP = subnet's first address
ep="$endpoint"; [ -n "$ep" ] || ep="$(detect_endpoint_ip):${port}" # auto-detect endpoint if empty
pn="$name"; [ -n "$pn" ] || pn='client-1'
if [ -n "$subnet" ] && [ -n "$port" ]; then
local tmperr; tmperr="$(mktemp 2>/dev/null || echo /tmp/wgsetup.err)"
if config="$(_setup_noninteractive "$subnet" "$sip" "$port" "$ep" "$pn" 2>"$tmperr")"; then
ok=true
else
ok=false; config=''; msg="$(tr '\n' ' ' < "$tmperr" 2>/dev/null | head -c 120)"; [ -n "$msg" ] || msg='setup-failed'
fi
rm -f "$tmperr"
else
msg='setup-bad-args'
fi ;;
```
(The add-peer QR-sidecar block already fires for any `ok=true` action with a non-empty `config` — confirm it isn't restricted to `action=add-peer`. If it is, broaden its guard to `[ "$action" = add-peer ] || [ "$action" = setup ]` so setup's first peer also gets a QR.)
- [ ] **Step 3: Verify.** `bash -n` + shellcheck clean. Smoke: `bash docker/wg/clusev-wg.sh serve-request` (non-root) → hits `need_root`. `bash docker/wg/clusev-wg.sh help` still fine.
- [ ] **Step 4: Commit**
```bash
git add docker/wg/clusev-wg.sh
git commit -m "feat(wg): non-interactive setup action for the dashboard write-bridge"
```

## Task 2: WgBridge `setup` + component + UI
**Files:** Modify `app/Services/WgBridge.php`, `app/Livewire/Wireguard/Index.php`, `resources/views/livewire/wireguard/index.blade.php`, `lang/{de,en}/wireguard.php`; Test extend `WgBridgeTest` + `WireguardPageTest`
- [ ] **Step 1: WgBridge — add `setup`.** Add `'setup'` to `ACTIONS`, and a `validateArgs` case:
```php
case 'setup':
$subnet = (string) ($args['subnet'] ?? '');
$port = (string) ($args['port'] ?? '');
$endpoint = (string) ($args['endpoint'] ?? '');
$name = (string) ($args['name'] ?? '');
if (preg_match('#^\d{1,3}(\.\d{1,3}){3}/\d{1,2}$#', $subnet) !== 1) {
throw new \InvalidArgumentException('invalid subnet');
}
if (preg_match('/^\d{1,5}$/', $port) !== 1 || (int) $port < 1 || (int) $port > 65535) {
throw new \InvalidArgumentException('invalid port');
}
if ($endpoint !== '' && preg_match('/^[A-Za-z0-9.:_-]{1,128}$/', $endpoint) !== 1) {
throw new \InvalidArgumentException('invalid endpoint');
}
if (preg_match('/^[A-Za-z0-9._-]{1,64}$/', $name) !== 1) {
throw new \InvalidArgumentException('invalid name');
}
return ['subnet' => $subnet, 'port' => $port, 'endpoint' => $endpoint, 'name' => $name];
```
Add a `WgBridgeTest` case:
```php
public function test_setup_request_validates_and_writes(): void
{
$id = app(WgBridge::class)->request('setup', ['subnet' => '10.99.0.0/24', 'port' => '51820', 'endpoint' => '1.2.3.4:51820', 'name' => 'client-1']);
$this->assertMatchesRegularExpression('/^[A-Za-z0-9]{16,64}$/', $id);
$req = json_decode((string) file_get_contents(storage_path('app/restart-signal/wg-request.json')), true);
$this->assertSame('setup', $req['action']);
$this->assertSame('10.99.0.0/24', $req['subnet']);
}
public function test_setup_request_rejects_a_bad_subnet(): void
{
$this->expectException(\InvalidArgumentException::class);
app(WgBridge::class)->request('setup', ['subnet' => 'nope', 'port' => '51820', 'name' => 'c']);
}
```
- [ ] **Step 2: Component — add `setupWg()` + state.** In `app/Livewire/Wireguard/Index.php`, add properties (with defaults) + the method; and surface a failure message in `pollResult`. Properties:
```php
// first-time setup form
public string $setupSubnet = '10.99.0.0/24';
public string $setupPort = '51820';
public string $setupEndpoint = '';
public string $setupPeer = 'client-1';
```
Method:
```php
public function setupWg(WgBridge $bridge): void
{
$this->validate([
'setupSubnet' => ['required', 'regex:#^\d{1,3}(\.\d{1,3}){3}/\d{1,2}$#'],
'setupPort' => ['required', 'regex:/^\d{1,5}$/'],
'setupEndpoint' => ['nullable', 'regex:/^[A-Za-z0-9.:_-]{1,128}$/'],
'setupPeer' => ['required', 'regex:/^[A-Za-z0-9._-]{1,64}$/'],
], [
'setupSubnet.regex' => __('wireguard.subnet_invalid'),
'setupPort.regex' => __('wireguard.port_invalid'),
'setupEndpoint.regex' => __('wireguard.endpoint_invalid'),
'setupPeer.regex' => __('wireguard.peer_name_invalid'),
]);
if ((int) $this->setupPort < 1 || (int) $this->setupPort > 65535) {
$this->addError('setupPort', __('wireguard.port_invalid'));
return;
}
if (! $this->throttle()) {
return;
}
$this->pendingId = $bridge->request('setup', [
'subnet' => $this->setupSubnet, 'port' => $this->setupPort,
'endpoint' => $this->setupEndpoint, 'name' => $this->setupPeer,
]);
$this->pendingAction = 'setup';
$this->audit('wg.setup', $this->setupSubnet);
}
```
In `pollResult`, broaden the config-surfacing branch to include `setup`, and surface the host message on failure. Change the success/failure handling to:
```php
if ($res['ok'] && in_array($this->pendingAction, ['add-peer', 'setup'], true) && $res['config'] !== null) {
$this->resultConfig = $res['config'];
$this->resultQr = $res['qr'];
} elseif (! $res['ok']) {
$msg = $res['message'] !== '' ? $res['message'] : __('wireguard.action_failed');
$this->dispatch('notify', message: $msg, level: 'error');
} else {
$this->dispatch('notify', message: __('wireguard.action_done'));
}
```
Add a `WireguardPageTest` case:
```php
public function test_setup_writes_a_request_and_audits(): void
{
\Livewire\Livewire::test(\App\Livewire\Wireguard\Index::class)
->set('setupSubnet', '10.99.0.0/24')->set('setupPort', '51820')->set('setupEndpoint', '1.2.3.4:51820')->set('setupPeer', 'client-1')
->call('setupWg')
->assertSet('pendingId', fn ($v) => is_string($v) && $v !== '');
$this->assertTrue(\App\Models\AuditEvent::where('action', 'wg.setup')->exists());
@unlink(storage_path('app/restart-signal/wg-request.json'));
}
public function test_setup_rejects_a_bad_subnet(): void
{
\Livewire\Livewire::test(\App\Livewire\Wireguard\Index::class)
->set('setupSubnet', 'nope')->set('setupPort', '51820')->set('setupPeer', 'c')
->call('setupWg')
->assertHasErrors('setupSubnet');
}
```
- [ ] **Step 3: Lang** (BOTH files, identical keys):
```php
'setup_title' => 'WireGuard einrichten',
'setup_intro' => 'Tunnel direkt hier einrichten. Das Gate bleibt danach AUS — das Panel ist weiter öffentlich, bis du es einschaltest.',
'setup_subnet' => 'Subnetz',
'setup_port' => 'Listen-Port (UDP)',
'setup_endpoint' => 'Öffentlicher Endpoint (optional)',
'setup_endpoint_hint' => 'Leer = automatisch erkannte öffentliche IP. Hinter NAT/Cloud-LB manuell setzen.',
'setup_peer' => 'Name des ersten Clients',
'setup_submit' => 'Einrichten',
'setup_or_ssh' => 'Alternativ per SSH:',
```
EN: Set up WireGuard / Set the tunnel up right here. The gate stays OFF afterwards — the panel remains public until you turn it on. / Subnet / Listen port (UDP) / Public endpoint (optional) / Empty = auto-detected public IP. Behind NAT/cloud LB set it manually. / First client name / Set up / Or over SSH:
- [ ] **Step 4: UI — replace the unconfigured empty state** in `resources/views/livewire/wireguard/index.blade.php`. The current `@if (! $status['configured'])` block shows only the SSH hint. Replace its body with a setup form + the SSH line as the secondary option:
```blade
<x-panel :title="__('wireguard.setup_title')">
<p class="text-sm leading-relaxed text-ink-2">{{ __('wireguard.setup_intro') }}</p>
<form wire:submit="setupWg" class="mt-4 space-y-3">
<div class="grid grid-cols-1 gap-3 sm:grid-cols-2">
<div>
<label class="font-mono text-[11px] text-ink-3">{{ __('wireguard.setup_subnet') }}</label>
<input wire:model="setupSubnet" type="text" maxlength="18" class="mt-1 w-full rounded-md border border-line bg-inset px-3 py-1.5 font-mono text-sm text-ink focus:border-accent/40 focus:outline-none" />

</div>
</div>
<p class="font-mono text-[10px] text-ink-4">{{ __('wireguard.setup_endpoint_hint') }}</p>
<div class="flex items-center gap-3">
<x-btn variant="primary" type="submit" wire:loading.attr="disabled" wire:target="setupWg">
<x-icon name="plus" class="h-3.5 w-3.5" />{{ __('wireguard.setup_submit') }}
</x-btn>
@if ($pendingId)
<span class="font-mono text-[11px] text-ink-3" wire:poll.2s="pollResult">{{ __('wireguard.pending') }}</span>
@endif
</div>
</form>
<p class="mt-4 font-mono text-[11px] text-ink-4">{{ __('wireguard.setup_or_ssh') }}</p>
<pre class="mt-1 overflow-x-auto rounded-md border border-line bg-void px-3 py-2.5 font-mono text-[11px] text-ink-2">sudo clusev wg setup</pre>
</x-panel>
```
(Keep the existing show-once result modal at the bottom of the root div — it already renders `$resultConfig`/`$resultQr` and now fires for setup too. Add a `wire:poll.2s="pollResult"` path for the unconfigured state via the pending span above so the result is picked up.)
- [ ] **Step 5: Run `… php artisan test --filter='WgBridgeTest|WireguardPageTest'` → all pass.** Pint.
- [ ] **Step 6: Commit**
```bash
git add app/Services/WgBridge.php app/Livewire/Wireguard/Index.php resources/views/livewire/wireguard/index.blade.php lang/de/wireguard.php lang/en/wireguard.php tests/Feature/WgBridgeTest.php tests/Feature/WireguardPageTest.php
git commit -m "feat(wg): set WireGuard up from the dashboard (setup form + bridge action)"
```
---
## Task 3: review + R12 + release
- [ ] **Step 1: Security spot-review** the `setup` action: arg re-validation host-side (subnet CIDR + collision, port range, endpoint charset, name); the heredoc config write (no injection — charsets exclude newline); refuses to clobber; does NOT touch the gate. App-side `WgBridge` validates the setup args; `setupWg` throttles + audits. Fix findings.
- [ ] **Step 2: shellcheck + Pint + full suite** green.
- [ ] **Step 3: R12** — `/wireguard` in the UNCONFIGURED state (no wg-status.json or `configured:false`): the setup form renders; submitting it writes a `setup` request (poller appears); with the host simulated (write a `wg-result-<id>.json` with a config + QR), the show-once modal appears with the first peer config. 1280 + 375, DE + EN, no console errors, no leaked tokens. Restore the gkonrad password + clean stubs.
- [ ] **Step 4: Release** v0.9.38 — CHANGELOG (Hinzugefügt: WireGuard-Erst-Einrichtung aus dem Dashboard — SP2 jetzt wirklich vollständig; korrigiert die in 0.9.37 zu eng gefasste Funktion), bump, commit, tag, push.
---
## Self-Review
**Spec coverage:** spec §5 "first-time setup from the UI" — previously deferred, now implemented (Tasks 1–2). The user's explicit requirement (everything from the dashboard) is met: status (P1), traffic (P2), peers (P3), settings+gate (P4), **setup (P5)**.
**Placeholder scan:** none.
**Type/name consistency:** `setup` action in `WgBridge::ACTIONS` + `validateArgs` + the host `serve-request` `setup)` branch + `_setup_noninteractive` + the component `setupWg` + the form fields `setupSubnet/setupPort/setupEndpoint/setupPeer`. The result (first peer config + QR) reuses the P3 `resultConfig`/`resultQr`/show-once modal; `pollResult` now treats `setup` like `add-peer`.
**Safety:** setup does NOT enable the gate (no lock-out — the panel stays public until the operator toggles it). Host re-validates every arg + runs the collision check; a colliding subnet fails with the host message surfaced to the UI. The interactive SSH `clusev wg setup` remains as an alternative.
