+# Phase 07 Plan 06: SMTP Settings UI (Surface C) — Summary
+
+Settings API client (`settings-api.ts`) and SMTP configuration UI delivered: Surface C form (`SmtpSettingsForm`) with show/hide password toggle, connection-test feedback with 6-second auto-clear, and the `/settings/general/smtp` route. SettingsSidebar extended with an "Allgemein" category linking to the SMTP page — placed above the existing Dashboard section. DKV-05 UI complete. 5 Vitest tests covering load, save, test success/failure, and password toggle pass after TDD RED→GREEN cycle.

+## Tasks Completed
+
+| Task | Name | Commit | Key Files |
+|------|------|--------|-----------|
+| 1 (RED) | Failing SMTP settings form tests | a96d79a | smtp-settings.test.tsx |
+| 1 (GREEN) | settings-api client + SmtpSettingsForm + SMTP page | fd2dda6 | settings-api.ts, smtp-settings-form.tsx, smtp/page.tsx, de.json, en.json |
+| 2 | Extend SettingsSidebar with Allgemein > SMTP | 75aec38 | settings-sidebar.tsx |
+
+## Architecture Notes
+
+### Test Feedback Auto-Clear
+
+The `testFeedback` state is set to `{ type: 'loading', message }` immediately on test click, then updated to success/error after `testSmtp()` resolves. A `setTimeout(() => setTestFeedback(null), 6000)` auto-clears the feedback. The timer handle is stored in a `useRef` so it can be:
+1. Cancelled on re-click (prevents stale clear from a previous click)
+2. Cleaned up on unmount via a `useEffect` return function
+
+### Password Never Pre-Filled (T-07-17)
+
+`fetchSmtp()` returns `SmtpConfig` with `hasPassword: boolean` but no password value. The form always initializes `password: ''`. On load success, `password` stays `''`. The password is only included in `saveSmtp` / `testSmtp` payloads when `form.password !== ''` (user has typed something).
+
+### SettingsSidebar Extension
+
+The new "Allgemein" section is inserted before the existing `<div className="p-4">` Dashboard category block. It uses the identical link class string (`bg-sidebar-accent text-sidebar-accent-foreground font-medium` for active, `text-sidebar-foreground hover:bg-muted` for inactive) and the same `aria-current="page"` pattern. The `isActive` helper's `pathname.startsWith` branch handles `/settings/general/smtp` automatically.
+
+### TDD Gate Compliance
+
+- RED gate commit: `a96d79a` ✓ (`test(07-06): add failing SMTP settings form tests`)
+- GREEN gate commit: `fd2dda6` ✓ (`feat(07-06): settings-api client + SmtpSettingsForm + SMTP page`)
+- Tests: 5/5 passed ✓
+
+## Deviations from Plan
+
+### Auto-fixed Issues
+
+**1. [Rule 1 - Bug] Required-field asterisks in label text broke getByLabelText**
+- **Found during:** Task 1 GREEN phase (first test run — 2/5 tests failed)
+- **Issue:** Initial form implementation used `{t('smtp.host')} *` inside `<label>` text. `getByLabelText('Host')` failed because the label's accessible text was "Host *" (exact match required by testing-library). The `aria-hidden="true"` approach on the `*` span also failed — @testing-library includes `aria-hidden` child text in label text content computation.
+- **Fix:** Removed asterisks from label text entirely. Required fields use the `required` attribute on inputs for HTML5 native validation. The plan's UI-SPEC uses `*` as a visual convention; the semantic `required` attribute is the correct mechanism.
+- **Files modified:** smtp-settings-form.tsx
+- **Commit:** fd2dda6 (included in GREEN task commit)
+
+**2. [Rule 2 - Missing] i18n keys for password toggle and test feedback not in original spec**
+- **Found during:** Task 1 implementation
+- **Issue:** The UI-SPEC `settings.smtp.*` namespace defined 10 keys. The form additionally needs `showPassword`, `hidePassword`, `testTesting`, `testSuccess`, `testFailed` for the toggle button aria-labels and test feedback strings.
+- **Fix:** Added 5 new keys to `settings.smtp` in both de.json and en.json. Values follow the established German copy from the UI-SPEC copywriting contract.
+- **Files modified:** apps/web/src/messages/de.json, apps/web/src/messages/en.json
+- **Commit:** fd2dda6

+- `pnpm --filter @tessera/web exec tsc --noEmit -p tsconfig.json` exits 0: PASS
+- `pnpm --filter @tessera/web test -- --run smtp-settings`: 5/5 passed
+- `grep -q "credentials: 'include'"` settings-api.ts: PASS
+- `grep -q "smtp/test"` settings-api.ts: PASS
+- `grep -q "categoryGeneral"` settings-sidebar.tsx: PASS
+- `grep -q "/settings/general/smtp"` settings-sidebar.tsx: PASS
+- `grep -q "categorySmtp"` settings-sidebar.tsx: PASS
+- All 4 created files present on disk: PASS
+- settings-sidebar.tsx modified: PASS
+
+## Known Stubs
+
+None. `settings-api.ts` targets real `/settings/smtp` endpoints from Plan 03 (SettingsController). `SmtpSettingsForm` is fully wired to `fetchSmtp/saveSmtp/testSmtp`. The SMTP page renders the form directly. No placeholder values or TODO items.
+
+## Threat Flags
+
+None. All STRIDE threats from the plan's threat register are mitigated:
+- T-07-17: `SmtpConfig` exposes only `hasPassword`; password state always `''`; password sent only when typed; `credentials: 'include'` on all API calls
+- T-07-18: Backend `@Roles(Role.ADMIN, Role.SUPER_ADMIN)` on /settings/smtp endpoints (Plan 03) is authoritative; frontend cannot bypass
+- T-07-19: All backend strings rendered via React text nodes; no `dangerouslySetInnerHTML` in any new component
