# Phase 7 — UI Design Contract: DKV Fleet Module

> Visual and interaction contract for frontend phases. Generated by gsd-ui-researcher, verified by gsd-ui-checker.
>
> This module spans **3 frontend surfaces**: module main page (history + exports),
> module settings page (inbox config + vehicle CRUD), and general settings SMTP page.
> Sections beyond the base template are phase-specific extensions required for a
> multi-surface module.

---

## Design System

| Property | Value | Source |
|----------|-------|--------|
| Tool | manual — shadcn CSS-variable convention; no CLI (`components.json` absent) | codebase audit |
| Preset | not applicable | — |
| Component library | manual hand-written components following shadcn token convention (no Radix dependency) | codebase audit |
| Icon library | inline SVG only — no external icon package | codebase audit (admin-sidebar.tsx) |
| Font | Inter via `var(--font-sans)` — system-ui fallback | globals.css |
| Border radius | `var(--radius)` = 0.5rem (8px) | globals.css |
| Color space | OKLCH throughout | globals.css |

**Registry safety:** Not applicable — no `components.json`, no CLI registry consumption.
**shadcn gate:** components.json NOT found. Project has established manual approach; do not initialize CLI. All new components must hand-write following existing patterns in `apps/web/src/components/`.

---

## Spacing Scale

Declared values (must be multiples of 4). Source: codebase audit of existing components.

| Token | Value | Tailwind class | Usage |
|-------|-------|----------------|-------|
| xs | 4px | `gap-1`, `p-1` | Icon gaps, inline element padding |
| sm | 8px | `gap-2`, `p-2` | Compact element spacing, icon-to-label gap |
| md | 12px | `px-3`, `py-1.5` | Input padding (h-9 pattern), nav item padding |
| lg | 16px | `p-4`, `gap-4` | Default section padding, form field gap |
| xl | 24px | `p-6`, `gap-6` | Card padding, section breaks |
| 2xl | 32px | `gap-8` | Layout column gaps |
| 3xl | 48px | — | Major page-level spacing |

**Exceptions:** none for this phase.

**Standard form element heights (from existing `CalendarSourceForm` pattern):**
- Input height: `h-9` (36px)
- Input max-width: `max-w-md` (448px) — do not exceed on settings forms
- Button: `px-4 py-2` (16px / 8px)

---

## Typography

Declared sizes from codebase audit (`grep -r text-* apps/web/src/components`):

| Role | Size | Tailwind | Weight | Line Height | Usage |
|------|------|----------|--------|-------------|-------|
| Display | 24px | `text-2xl` | 700 (`font-bold`) | 1.2 | Module page `<h1>` — follows `modules/domaincheck/page.tsx` |
| Heading | 18px | `text-lg` | 600 (`font-semibold`) | 1.3 | Settings page `<h1>`, section titles — follows `settings/dashboard/page.tsx` |
| Body | 14px | `text-sm` | 400 (`font-normal`) | 1.5 | Form labels, table cells, nav items, general text |
| Label | 12px | `text-xs` | 600 (`font-semibold`) | 1.0 | Section category labels (uppercase + tracking-wider), table column headers, status badges |

**Declared weights:** 400 (regular) and 600 (semibold). Exception: Display uses 700 per existing module page convention (`font-bold`) — do not introduce 700 weight elsewhere in this phase.

**Section category label pattern** (from `settings-sidebar.tsx` and `admin-sidebar.tsx`):
```
text-xs font-semibold uppercase tracking-wider text-muted-foreground
```
Use this verbatim for sidebar category headings and table `<thead>` column labels.

---

## Color

All values from `apps/web/src/app/globals.css`. OKLCH color space. Dual light/dark mode support is mandatory for all new components.

| Role | CSS Token | Light Value | Dark Value | Usage |
|------|-----------|-------------|------------|-------|
| Dominant (60%) | `var(--background)` | oklch(0.99 0 0) | oklch(0.23 0.01 260) | Page background, main content area |
| Secondary (30%) | `var(--card)` | oklch(1 0 0) | oklch(0.27 0.01 260) | Table container, form panels, export file list |
| — | `var(--sidebar)` | oklch(0.97 0 0) | oklch(0.20 0.01 260) | Settings sidebar background |
| — | `var(--muted)` | oklch(0.96 0 0) | oklch(0.30 0.01 260) | Table row hover, disabled field backgrounds |
| Accent (10%) | `var(--primary)` | oklch(0.91 0.19 102) | oklch(0.91 0.19 102) | Primary CTA only — see reserved list below |
| Destructive | `var(--destructive)` | oklch(0.55 0.2 27) | oklch(0.55 0.2 27) | Delete vehicle, destructive CSV replace, error text |
| Border | `var(--border)` | oklch(0.90 0 0) | oklch(0.30 0.01 260) | Input borders, table borders, dividers |
| Muted text | `var(--muted-foreground)` | oklch(0.55 0 0) | oklch(0.65 0 0) | Placeholder text, secondary info, empty states |

**Accent (`var(--primary)`) is reserved for:**
- "Jetzt prüfen" button background
- Active state indicator in tab bar (border-bottom line)
- Focus ring (`var(--ring)`) on focused inputs
- Export file download links (text color: `text-primary`)
- Active settings sidebar item (`bg-sidebar-accent text-sidebar-accent-foreground`)

**Accent is NOT used for:** passive table borders, section headings, helper text, secondary buttons, status indicators.

### Status Badge Colors (new — not in globals.css)

These values are defined inline in the `StatusBadge` component. Do NOT add to globals.css for v1.

| State | Label | Text | Background |
|-------|-------|------|-----------|
| Verarbeitet | "Verarbeitet" | `oklch(0.40 0.15 148)` (green) | `oklch(0.40 0.15 148 / 0.10)` |
| Fehler | "Fehler" | `var(--destructive)` | `oklch(0.55 0.2 27 / 0.10)` |
| Versand fehlgeschlagen | "Versand fehlgeschlagen" | `oklch(0.50 0.13 70)` (amber) | `oklch(0.50 0.13 70 / 0.10)` |

Badge shape: `rounded-full px-2 py-0.5 text-xs font-medium`

---

## Copywriting Contract

All UI strings are German (the portal language for this tenant). i18n keys are listed in the Phase-Specific Extensions section below.

| Element | Copy |
|---------|------|
| Primary CTA (manual trigger) | "Jetzt prüfen" |
| CTA loading state | "Wird geprüft..." |
| Last checked timestamp | "Zuletzt geprüft: {TT.MM.JJJJ, HH:mm} Uhr" |
| Never checked | "Noch nie geprüft" |
| Add vehicle button | "Fahrzeug hinzufügen" |
| CSV import button | "CSV importieren" |
| Save (forms) | "Speichern" |
| Cancel | "Abbrechen" |
| Test SMTP connection | "Verbindung testen" |
| History empty state heading | "Noch keine Rechnungen verarbeitet" |
| History empty state body | "Klicke auf 'Jetzt prüfen', um den Posteingang zu prüfen. Neue Rechnungen erscheinen hier automatisch." |
| Vehicle table empty state heading | "Keine Fahrzeuge hinterlegt" |
| Vehicle table empty state body | "Füge Fahrzeuge manuell hinzu oder lade eine CSV-Datei hoch." |
| Export files empty | "Noch keine Exportdateien vorhanden" |
| Poll error banner | "Posteingang konnte nicht geprüft werden. Überprüfe die Konfiguration unter 'Moduleinstellungen › Posteingang'." |
| SMTP send failure (in history badge tooltip) | "Export wurde erstellt, konnte aber nicht gesendet werden. Die Datei ist weiterhin zum Download verfügbar." |
| SMTP test success | "Verbindung erfolgreich" |
| SMTP test failure | "Verbindung fehlgeschlagen: {fehlermeldung}" |
| Delete vehicle — dialog title | "Fahrzeug löschen" |
| Delete vehicle — dialog body | "Das Fahrzeug {Kennzeichen} wird dauerhaft aus der Stammdatenliste entfernt. Diese Aktion kann nicht rückgängig gemacht werden." |
| Delete vehicle — confirm button | "Löschen" (destructive style) |
| CSV replace — dialog title | "Fahrzeuge ersetzen?" |
| CSV replace — dialog body | "Alle vorhandenen Fahrzeuge werden durch die CSV-Daten ersetzt. Diese Aktion kann nicht rückgängig gemacht werden." |
| CSV replace — confirm button | "Ersetzen" (destructive style) |
| CSV import success toast | "{count} Fahrzeuge importiert" |

**Destructive action pattern:** Both destructive actions use an inline dialog/modal (not a toast). Confirm button uses `bg-destructive text-destructive-foreground` style. Cancel is always leftmost and uses secondary button style.

## Registry Safety

| Registry | Blocks Used | Safety Gate |
|----------|-------------|-------------|
| shadcn official | none | not required — no CLI |
| third-party | none | not applicable |

---

## Phase-Specific Extensions

The following sections are required for multi-surface modules. gsd-executor must treat these as binding visual contracts identical to the base sections above.

---

### UI Surfaces Overview

| Surface | Route | Purpose |
|---------|-------|---------|
| A — Module Main | `/modules/dkv-fleet` | Invoice history table + export download list + "Jetzt prüfen" trigger |
| B — Module Settings | `/modules/dkv-fleet/settings` | Inbox config form (tab 1) + vehicle master CRUD table (tab 2) |
| C — General Settings SMTP | `/settings/general/smtp` | Shared SMTP configuration (extends SettingsSidebar with new category) |

---

### Surface A: Module Main Page

**File:** `apps/web/src/app/(portal)/modules/dkv-fleet/page.tsx`

**Layout (top to bottom):**

```
[ Page Header Row                                                    ]
  <h1>DKV Flotte</h1>            [Jetzt prüfen] ← right-aligned button
  <p>Zuletzt geprüft: …</p>      ← text-sm text-muted-foreground

[ Error Banner (conditional — only on poll failure)                 ]
  border border-destructive/30 bg-destructive/10 px-4 py-3 text-sm text-destructive
  + × close button (right-aligned in banner)

[ Invoice Processing History                                         ]
  <h2>Verarbeitungshistorie</h2>  ← text-lg font-semibold mb-4
  <InvoiceHistoryTable />

[ Last Export Files                                                  ]
  <h2>Letzte Exportdateien</h2>  ← text-sm font-semibold mb-2 mt-6
  <ExportFileList />
```

**InvoiceHistoryTable specification:**

Column headers: `text-xs font-semibold uppercase tracking-wider text-muted-foreground` with `px-4 py-3 border-b border-border`

| # | Column Header | Data Format | Width | Alignment |
|---|---------------|-------------|-------|-----------|
| 1 | DATUM/ZEIT | "26.06.2026, 14:32 Uhr" | 160px | left |
| 2 | RECHNUNGSNUMMER | string (e.g. "26-651566449-001") | 200px | left |
| 3 | FAHRZEUGE | number | 100px | right |
| 4 | TRANSAKTIONEN | number | 120px | right |
| 5 | STATUS | `<StatusBadge>` component | 180px | left |
| 6 | EXPORTDATEI | download link or "–" em dash | auto | left |

Table rows: `px-4 py-3 text-sm`, hover: `hover:bg-muted/50 transition-colors`
Table container: `rounded border border-border overflow-hidden`
Initial loading: 5 skeleton rows — each cell is `h-4 rounded bg-muted animate-pulse`
Pagination: show when > 25 rows. Pattern: `"Zeige 1–25 von {total}"` text-sm text-muted-foreground + [← Zurück] [Weiter →] buttons (secondary style, disabled when at limits)

**Export file in column 6:**
- If present: inline SVG download icon (16×16, currentColor) + filename as `<a href="/api/dkv/exports/{filename}" download>` — `text-primary text-sm hover:underline`
- If absent: `<span class="text-muted-foreground">–</span>`

**ExportFileList specification:**

Each entry on its own line:
```
[↓ icon 16×16]  DKV_2026-04_26-651566449-001.xlsx   (142 KB)
```
- Icon: inline SVG download arrow, `text-muted-foreground`
- Filename: `<a>` with `text-sm text-primary hover:underline`
- Size: `text-xs text-muted-foreground ml-2`
- Empty state: `<p class="text-sm text-muted-foreground">Noch keine Exportdateien vorhanden</p>`
- Max 10 entries (enforced server-side)

**"Jetzt prüfen" button states:**

| State | Classes | Disabled | Content |
|-------|---------|---------|---------|
| Idle | `rounded bg-primary px-4 py-2 text-sm font-medium text-primary-foreground transition-colors hover:bg-primary/90` | no | "Jetzt prüfen" |
| Loading | `... opacity-80 cursor-not-allowed` | yes | inline spinner SVG (20×20, animate-spin) + "Wird geprüft..." |
| Success | returns to Idle; table re-fetches | no | "Jetzt prüfen" |
| Error | returns to Idle; error banner appears above table | no | "Jetzt prüfen" |

Spinner SVG: `<svg class="mr-2 h-4 w-4 animate-spin" ...>` — standard circular spinner path, `stroke="currentColor"`.

---

### Surface B: Module Settings Page

**File:** `apps/web/src/app/(portal)/modules/dkv-fleet/settings/page.tsx`

**Layout:**
- Page heading: `<h1 class="text-2xl font-bold tracking-tight mb-6">Moduleinstellungen</h1>`
- Tab bar immediately below heading (NOT a sub-sidebar — inline tabs)
- Active tab: bottom border `border-b-2 border-primary text-foreground font-medium`
- Inactive tab: `text-muted-foreground hover:text-foreground`
- Tab padding: `px-4 py-2 text-sm`
- Tab bar separator: `border-b border-border mb-6`

**Tab 1: Posteingang → InboxConfigForm**

File: `apps/web/src/app/(portal)/modules/dkv-fleet/settings/components/InboxConfigForm.tsx`

Form fields (in order, all follow CalendarSourceForm pattern):

```
Protokoll *          [select: IMAP | Exchange]
Host *               [text input]
Port *               [number input]
Verschlüsselung *    [select: Keine | STARTTLS | SSL-TLS]
Ordner *             [text input, default "INBOX"]
Absenderfilter       [email input, optional — placeholder: "rechnung@dkv.com"]
Abrufintervall *     [number input, min=5, suffix label "Minuten"]
Benutzername         [text input, optional]
Passwort             [password input, optional, with show/hide toggle button]
Export-Empfänger *   [email input]
Fahrzeug-Formatstring*[text input, default "{Marke}/{Modell}/{Kennzeichen}"]
                     [help text below: text-xs text-muted-foreground
                      "Verfügbare Platzhalter: {Marke}, {Modell}, {Kennzeichen}, {Fahrer}"]
Aktiv                [toggle — visual: rounded pill, primary color when on]
```

Show/hide password toggle: inline button at right edge of input (`type="button"`, no border, shows eye/eye-off inline SVG 16×16). Input changes `type` attribute between `"password"` and `"text"`.

Active toggle: `<button role="switch" aria-checked={isActive}>` — pill shape:
- On: `bg-primary` with white circle
- Off: `bg-muted` with white circle
- Width: 40px, height: 22px

Form actions row: `flex gap-3 pt-4 border-t border-border mt-6`
- "Verbindung testen" (secondary button, left) — tests IMAP/Exchange connection
- "Speichern" (primary button)
- Inline feedback below buttons: success in green (`text-sm` at oklch(0.40 0.15 148)) or error in destructive (`text-sm text-destructive`)

**Tab 2: Fahrzeuge → VehicleTable + CsvImportButton**

File: `apps/web/src/app/(portal)/modules/dkv-fleet/settings/components/VehicleTable.tsx`

Table toolbar (above table): `flex justify-between items-center mb-3`
- Left: "Fahrzeuge" count badge — `text-sm text-muted-foreground` e.g. "27 Fahrzeuge"
- Right: [CSV importieren] (secondary button) + [Fahrzeug hinzufügen] (primary button), `gap-2`

Table columns (same header style as InvoiceHistoryTable):

| Column | Width | Input type in edit mode |
|--------|-------|------------------------|
| KENNZEICHEN | 140px | text, `uppercase` |
| MARKE | 140px | text |
| MODELL | 180px | text |
| FAHRER | 200px | text (format: "Vorname Nachname") |
| AKTIONEN | 80px | — |

**Row modes:**
- View mode: plain text cells + pencil icon button + trash icon button in AKTIONEN column
- Edit mode: text inputs replace cells (same `h-9 rounded border border-border bg-background px-2 text-sm` but without `max-w-md` constraint) + checkmark (save) + × (cancel) icon buttons

Icon buttons in AKTIONEN: `p-1 rounded text-muted-foreground hover:text-foreground hover:bg-muted transition-colors`
- Pencil: 16×16 inline SVG
- Trash: 16×16 inline SVG, `hover:text-destructive`
- Checkmark (save): 16×16, `hover:text-primary`
- ×  (cancel): 16×16

"Add vehicle" row: clicking [Fahrzeug hinzufügen] appends a new empty edit-mode row at bottom of table.

File: `apps/web/src/app/(portal)/modules/dkv-fleet/settings/components/CsvImportButton.tsx`

Hidden `<input type="file" accept=".csv">`. Clicking [CSV importieren] triggers the hidden input.

After file selected → inline dialog (NOT a full modal; a contained `<div>` in the page below the button, with border and padding):
```
Importmodus:
○ Zusammenführen — neue Fahrzeuge hinzufügen, vorhandene behalten  (default)
● Ersetzen — alle vorhandenen Fahrzeuge löschen und neu importieren
  ↳ [Warning text, text-xs text-destructive]: "Alle vorhandenen Fahrzeuge werden ersetzt."

[Abbrechen]  [Importieren]
```
"Importieren" with Replace mode selected → destructive confirm dialog (standard browser-style: title + body + [Abbrechen] [Ersetzen])

Post-import: inline success message `text-sm` at green color + auto-dismiss after 4 seconds + table refresh.

---

### Surface C: General Settings SMTP

**File:** `apps/web/src/app/(portal)/settings/general/smtp/page.tsx`

**SettingsSidebar extension** (`apps/web/src/components/settings/settings-sidebar.tsx`):

Add new "Allgemein" section **above** the existing "Dashboard" section:

```tsx
// New section — insert before existing Dashboard items
<div className="p-4 pb-2">
  <h2 className="text-xs font-semibold uppercase tracking-wider text-muted-foreground">
    {t('categoryGeneral')}
  </h2>
</div>
<nav className="flex flex-col gap-1 px-3 mb-2">
  <Link href="/settings/general/smtp" ...>
    {t('categorySmtp')}
  </Link>
</nav>
```

Active/inactive link styling: identical to existing items in `settings-sidebar.tsx` (copy verbatim).

**SmtpConfigForm:**

File: `apps/web/src/app/(portal)/settings/general/smtp/components/SmtpConfigForm.tsx`

Page heading: `<h1 class="mb-6 text-lg font-semibold text-foreground">SMTP-Konfiguration</h1>` — follows `settings/dashboard/page.tsx` heading pattern exactly.

Form fields (in order, follow CalendarSourceForm pattern, `max-w-md` on all inputs):

```
Host *               [text input, placeholder: "smtp.example.com"]
Port *               [number input, default 587]
Verschlüsselung *    [select: Keine | STARTTLS | SSL-TLS, default STARTTLS]
Benutzername         [text input, optional]
Passwort             [password input, optional, with show/hide toggle]
Absenderadresse *    [email input, placeholder: "tessera@example.com"]
                     [help text: "Die E-Mail-Adresse, die als Absender angezeigt wird."]
```

Form actions row: `flex gap-3 pt-2`
- "Speichern" (primary button)
- "Verbindung testen" (secondary button)

Connection test feedback: appears below the action row:
- Loading: `text-sm text-muted-foreground` — "Verbindung wird getestet..."
- Success: `text-sm` green — "Verbindung erfolgreich"
- Error: `text-sm text-destructive` — "Verbindung fehlgeschlagen: {fehlermeldung}"
- Auto-clears after 6 seconds

---

### StatusBadge Component

**File:** `apps/web/src/app/(portal)/modules/dkv-fleet/components/StatusBadge.tsx`

```
type Status = 'Verarbeitet' | 'Fehler' | 'Versand fehlgeschlagen'
props: { status: Status; errorMessage?: string }
```

Shape: `<span class="inline-flex items-center rounded-full px-2 py-0.5 text-xs font-medium">`

Colors (inline style — not CSS classes, as these OKLCH values are not in Tailwind config):
- Verarbeitet: `color: oklch(0.40 0.15 148)`, `background: oklch(0.40 0.15 148 / 0.10)`
- Fehler: `color: var(--destructive)`, `background: oklch(0.55 0.2 27 / 0.10)`
- Versand fehlgeschlagen: `color: oklch(0.50 0.13 70)`, `background: oklch(0.50 0.13 70 / 0.10)`

"Fehler" and "Versand fehlgeschlagen" states: add `title={errorMessage}` attribute when `errorMessage` is provided — renders browser tooltip on hover.

---

### Interaction Contracts Summary

| Interaction | Trigger | Feedback | Error handling |
|------------|---------|---------|----------------|
| "Jetzt prüfen" | button click | loading state on button; table refetch on success | error banner above table; button re-enables |
| Delete vehicle | trash icon click | confirm dialog appears | none (server error: inline `text-destructive` below table) |
| Edit vehicle row | pencil icon click | row switches to edit-mode inputs inline | validation: Kennzeichen required; inline `text-destructive text-xs` below field |
| Save vehicle row | checkmark click | row returns to view mode with new values | server error: `text-destructive text-xs` appears below row |
| CSV import | file selected | import mode dialog appears | file parse error: `text-destructive text-sm` in dialog |
| Save InboxConfig | "Speichern" click | button disables during save; re-enables on done | inline error below button |
| Test inbox connection | "Verbindung testen" click | inline loading → success/error text | shown inline below button |
| Save SmtpConfig | "Speichern" click | button disables during save; re-enables | inline error below button |
| Test SMTP | "Verbindung testen" click | inline loading → success/error text | shown inline, auto-clears 6s |
| Export file download | filename link click | browser download dialog | n/a (HTTP error: browser default) |

**Toast pattern:** Use only for async success states that don't have a natural location (e.g., CSV import success). Toast: fixed bottom-right, `rounded border border-border bg-card shadow-md px-4 py-3 text-sm`, auto-dismiss 4 seconds.
