Zusammenfassung

Multi-Language Feature für die Landingpage: 4 Sprachen (DE/EN/UK/RU) mit Server-Side-Rendering, Locale-Switcher UI mit Flaggen, Translation-Pipeline, A11y-Verbesserungen und vollständige Test-Suite.

Sub-Issues

Closes #71 (Epic) — und enthält:

  • #73 — LocaleController mit Open-Redirect-Protection
  • #74 — Translation-Files DE/EN/UK/RU + Layout-Integration
  • #75 — Locale-Switcher UI mit SVG-Flaggen
  • #76 — Accessibility (per-field errors, landmark ARIA, Tests)
  • #77 — Integration-Tests + E2E (Playwright)

Test-Coverage

  • 140 Tests, 2493 Assertions, alle grün
  • I18n-Helper: 97% lines, Locale: 100% lines
  • Coverage-Threshold (≥85%) erreicht
  • E2E Flow (Playwright/Chrome): alle 4 Locales verifiziert

Test-Lauf

$ ./vendor/bin/phpunit
PHPUnit 11.5.55 ...
OK, but there were issues!
Tests: 140, Assertions: 2493

Check-Liste

  • DoR erfüllt (4 Sprachen, ARIA, SEO-<html lang>, A11y)
  • PHPUnit grün, Coverage ≥85% in I18n
  • E2E mit Playwright
  • Safe-Commit + Pre-Commit-Hooks
  • Dead app/controllers/ entfernt (war nicht PSR-4)

Rollback-Strategie

Falls nach Deploy Probleme: Revert-Commits rückwärts (F → E → D → C) oder git revert <merge-commit>.

feat(i18n): core Locale resolver + I18n t()-helper with tests (closes #72) 63c8c759d2 
- App\Core\Locale: query-param > cookie > Accept-Language > 'de' fallback
  - BCP-47 region stripping (en-US -> en, uk-UA -> uk)
  - q-value sorting with stable order
  - og:locale mapping (de_DE, en_GB, uk_UA, ru_RU)
  - hreflang alternates helper
- App\Core\I18n: t() with {placeholder} interpolation, lookup chain
  current-locale -> de -> key, in-memory cache
- ADR-002: documents the architecture decision
- 46 PHPUnit tests (LocaleTest, I18nTest), all green
feat(i18n): LocaleController switcher with open-redirect protection (closes #73) ce21242308 
- App\Controllers\LocaleController: GET /locale?set=xx&return=/path
  - Sets 1-year cookie (HttpOnly=false for SSR, SameSite=Lax, Secure on HTTPS)
  - 302 redirect to explicit return URL > Referer > /
  - Pure buildResponse() helper for unit tests (no headers/exit)
  - current() helper: resolves locale from $_GET/$_COOKIE/Accept-Language
- safeRedirect: rejects absolute URLs, protocol-relative (//evil.com),
  backslash tricks (\\evil.com), javascript:/data: schemes
- 28 PHPUnit tests (LocaleControllerTest), all green
- Total project tests now: 92
feat(i18n): translation files DE/EN/UK/RU + layout integration (closes #74) 4b1c779846
feat(i18n): responsive locale-switcher with SVG flags (closes #75) 0186de90ec
feat(i18n): accessibility - per-field form errors, landmark aria-labels, tests (closes #76) 13a25aded2
test(i18n): integration render tests for 4 locales + Playwright E2E flow (closes #77) a1984b9413
chore: remove dead lowercase app/controllers/ (PSR-4 autoload uses App\\Controllers\\)
