-# Internationalization (i18n) Implementation Plan
-## State-of-the-Art Next.js 15 + FastAPI i18n System (2025)
-
-**Last Updated**: 2025-11-17
-**Status**: ✅ Approved - Ready for Implementation
-**Languages**: English (en) - Default, Italian (it) - Showcase
-
----
-
-## 📋 EXECUTIVE SUMMARY
-
-This document provides a comprehensive plan for implementing production-grade internationalization (i18n) in the FastNext Template. The implementation showcases best practices with 2 languages (English and Italian), making it easy for users to extend with additional languages.
-
-### Technology Stack (2025 Best Practices)
-
-- **Frontend**: next-intl 4.0 (ESM, TypeScript-first, App Router native)
-- **Backend**: FastAPI with BCP 47 locale storage in PostgreSQL
-- **Testing**: Playwright (parameterized locale tests) + Jest (i18n test utils)
-- **SEO**: Automatic hreflang tags, sitemap generation, metadata per locale
-- **Validation**: Automated translation key validation in CI/CD
-
-### Why Only 2 Languages?
-
-This is a **template showcase**, not a production deployment:
-
-✅ Clean example of i18n implementation
-✅ Easy to understand patterns
-✅ Users can add languages by copying the Italian example
-✅ Faster testing and implementation
-✅ Smaller bundle size for demonstration
-
-### Quality Standards
-
-- ✅ **Test Coverage**: Backend ≥97%, comprehensive E2E tests
-- ✅ **Zero Breaking Changes**: All existing 743 backend + 56 frontend tests must pass
-- ✅ **Type Safety**: Full autocomplete for translation keys
-- ✅ **Performance**: Core Web Vitals maintained (LCP < 2.5s, INP < 200ms, CLS < 0.1)
-- ✅ **SEO**: Lighthouse SEO score 100 for both locales
-- ✅ **GDPR Compliant**: User locale preferences handled appropriately
-
----
-

----
-
-## 🏗️ ARCHITECTURE DECISIONS
-
-### 1. Locale Format: BCP 47
-
-**Decision**: Use BCP 47 language tags (e.g., "en", "it", "en-US", "it-IT")
-
-**Rationale**:
-- Industry standard (used by HTTP Accept-Language, HTML lang attribute, ICU libraries)
-- Based on ISO 639-1 (language) + ISO 3166-1 (region)
-- Flexible: start simple with 2-letter codes, add region qualifiers when needed
-- Future-proof for dialects and scripts (e.g., "zh-Hans" for Simplified Chinese)
-
-**Implementation**:
-```python
-# Backend validation
-SUPPORTED_LOCALES = {"en", "it", "en-US", "en-GB", "it-IT"}
-```
-
----
-
-### 2. URL Structure: Subdirectory
-
-**Decision**: `/[locale]/[path]` format (e.g., `/en/about`, `/it/about`)
-
-**Alternatives Considered**:
-- ❌ Subdomain (`en.example.com`) - Too complex for template
-- ❌ Country-code TLD (`example.it`) - Too expensive, not needed for template
-- ❌ URL parameters (`?lang=en`) - Poor SEO, harder to crawl
-
-**Rationale**:
-- ✅ **Best SEO**: Google explicitly recommends subdirectories for most sites
-- ✅ **Simple Infrastructure**: Single domain, single deployment
-- ✅ **Low Cost**: No multiple domain purchases
-- ✅ **Easy to Maintain**: Centralized analytics and tooling
-- ✅ **Clear URLs**: Users can easily switch locales by changing URL
-
-**SEO Benefits**:
-- Domain authority consolidates to one domain
-- Backlinks benefit all language versions
-- Easier to build authority than multiple domains
-- Works seamlessly with hreflang tags
-
----
-
-### 3. Database Schema: Dedicated `locale` Column
-
-**Decision**: Add `locale VARCHAR(10)` column to `users` table, NOT JSONB
-
-**Alternatives Considered**:
-- ❌ Store in `preferences` JSONB field - 2-10x slower queries, no optimizer statistics
-
-**Rationale**:
-- ✅ **Performance**: B-tree index vs GIN index (smaller, faster)
-- ✅ **Query Optimization**: PostgreSQL can maintain statistics on column values
-- ✅ **Disk Space**: JSONB stores keys repeatedly (inefficient for common fields)
-- ✅ **Update Performance**: Updating JSONB requires rewriting entire field + indexes
-
-**Schema**:
-```sql
-ALTER TABLE users ADD COLUMN locale VARCHAR(10) DEFAULT NULL;
-CREATE INDEX ix_users_locale ON users(locale);
-```
-
-**Why Nullable?**
-- Distinguish "never set" (NULL) from "explicitly set to English"
-- Allows lazy loading on first request (more accurate than backfilling)
-
-**Why No Database DEFAULT?**
-- Application-level default provides more flexibility
-- Can implement locale detection logic (Accept-Language header)
-- Easier to change default without migration
-
----
-
-### 4. Locale Detection Priority
-
-**Decision**: Three-tier fallback system
-
-1. **User's Saved Preference** (highest priority)
-   - If authenticated and `user.locale` is set, use it
-   - Persists across sessions and devices
-
-2. **Accept-Language Header** (second priority)
-   - For unauthenticated users
-   - Parse `Accept-Language: it-IT,it;q=0.9,en;q=0.8` → "it-IT"
-   - Validate against supported locales
-
-3. **Default to English** (fallback)
-   - If no user preference and no header match
-
-**Implementation** (Backend):
-```python
-async def get_locale(
-    request: Request,
-    current_user: User | None = Depends(get_optional_current_user)
-) -> str:
-    if current_user and current_user.locale:
-        return current_user.locale
-
-    accept_language = request.headers.get("accept-language", "")
-    if accept_language:
-        locale = accept_language.split(',')[0].split(';')[0].strip()
-        lang_code = locale.split('-')[0].lower()
-        if lang_code in {"en", "it"}:
-            return locale.lower()
-
-    return "en"
-```
-
----
-
-### 5. Translation Storage: Server-Side Only (next-intl)
-
-**Decision**: Use next-intl's server-component pattern, NOT client-side translation loading
-
-**Rationale**:
-- ✅ **Zero Client Bundle Overhead**: Translations never sent to browser
-- ✅ **Instant Page Loads**: No translation parsing on client
-- ✅ **Better SEO**: Fully rendered HTML for search engines
-- ✅ **Reduced Bandwidth**: Especially important for mobile users
-
-**Implementation**:
-```typescript
-// Server Component (preferred 95% of the time)
-import { getTranslations } from 'next-intl/server';
-
-export default async function Page() {
-  const t = await getTranslations('HomePage');
-  return <h1>{t('title')}</h1>;
-}
-
-// Client Component (only when needed for interactivity)
-'use client';
-import { useTranslations } from 'next-intl';
-
-export function LoginForm() {
-  const t = useTranslations('auth.Login');
-  return <form>{/* ... */}</form>;
-}
-```
-
-**Performance Impact**:
-- next-intl core: ~9.2kb gzipped
-- Translation files: 0kb on client (server-side only)
-- Tree-shaking: Automatic with ESM build
-
----
-
-### 6. Translation File Structure: Nested Namespaces
-
-**Decision**: Use nested JSON structure with namespaces, not flat keys
-
-**Bad (Flat)**:
-```json
-{
-  "auth_login_title": "Sign in",
-  "auth_login_email_label": "Email",
-  "auth_register_title": "Sign up"
-}
-```
-
-**Good (Nested)**:
-```json
-{
-  "auth": {
-    "Login": {
-      "title": "Sign in",
-      "emailLabel": "Email"
-    },
-    "Register": {
-      "title": "Sign up"
-    }
-  }
-}
-```
-
-**Rationale**:
-- ✅ **Better Organization**: Logical grouping by feature
-- ✅ **Easier Maintenance**: Find related translations quickly
-- ✅ **Type Safety**: Full autocomplete with TypeScript integration
-- ✅ **Scalability**: Easy to split into separate files later
-
-**Usage**:
-```typescript
-const t = useTranslations('auth.Login');
-t('title');  // "Sign in"
-t('emailLabel');  // "Email"
-```
-
----
-
-### 7. SEO Strategy: Hreflang + Sitemap + Metadata
-
-**Decision**: Dual implementation for comprehensive SEO
-
-**1. HTML `<link>` Tags** (via `generateMetadata`):
-```typescript
-export async function generateMetadata({ params: { locale } }) {
-  return {
-    alternates: {
-      canonical: `/${locale}`,
-      languages: {
-        'x-default': '/en',
-        'en': '/en',
-        'it': '/it',
-      },
-    },
-  };
-}
-```
-
-**2. XML Sitemap** (with hreflang):
-```typescript
-export default function sitemap() {
-  return routes.flatMap(route =>
-    locales.map(locale => ({
-      url: `${baseUrl}/${locale}${route.path}`,
-      alternates: {
-        languages: { en: `/en${route.path}`, it: `/it${route.path}` }
-      }
-    }))
-  );
-}
-```
-
-**Why Both?**
-- HTML tags: Google's preferred method for page-level precision
-- Sitemap: Helps discovery, provides backup if HTML tags malfunction
-- **Never use HTTP headers** - avoid confusion with mixed methods
-
-**x-default Locale**:
-- Points to English (`/en`) as fallback for unsupported locales
-- Used when user's language doesn't match any hreflang tags
-
----
-
-### 8. Testing Strategy: Smoke Tests + Parameterization
-
-**Decision**: Don't test all translations, test the i18n mechanism works
-
-**Backend Tests**:
-- 10 new integration tests covering locale CRUD, validation, detection
-- Test both EN and IT locale values
-- Test Accept-Language header parsing
-
-**Frontend E2E Tests**:
-- 12 new parameterized tests for locale switching
-- Test critical flows in both EN and IT (login, register)
-- **NOT** duplicating all 56 existing tests per locale
-- Use parameterization: `for (const locale of ['en', 'it']) { test(...) }`
-
-**Frontend Unit Tests**:
-- 8 new component tests with i18n wrappers
-- Test LocaleSwitcher functionality
-- Test translated components render correctly
-
-**Translation Validation**:
-- Automated CI check for missing keys
-- Validate Italian has all keys that English has
-- Detect unused keys
-
-**Rationale**:
-- ✅ **Efficient**: Test mechanism, not content
-- ✅ **Maintainable**: Adding Italian tests doesn't double test time
-- ✅ **Comprehensive**: Critical paths tested in both locales
-- ✅ **Fast CI**: ~13-18 minutes total (vs 60+ if we duplicate everything)
-
----
-
-### 9. Performance Budget
-
-**Core Web Vitals Targets** (both EN and IT):
-- **LCP** (Largest Contentful Paint): < 2.5s
-- **INP** (Interaction to Next Paint): < 200ms
-- **CLS** (Cumulative Layout Shift): < 0.1
-
-**Bundle Size Impact**:
-- next-intl: ~9.2kb gzipped (acceptable)
-- Translation files: 0kb on client (server-side)
-- Total increase: < 15kb
-
-**Lighthouse Scores**:
-- Performance: ≥ 90
-- Accessibility: ≥ 95
-- SEO: 100
-
-**Font Loading Strategy**:
-- Use `display: swap` to prevent CLS
-- Preload Inter font with Latin + Latin-ext subsets (for Italian accents: à, è, ì, ò, ù)
-- Fallback to system fonts
-
----
-
-### 10. GDPR Compliance
-
-**Classification**: User locale preference IS personal data (GDPR Article 4)
-
-**Lawful Basis**: Legitimate interest (service improvement) ✅
-
-**User Rights**:
-- ✅ **Access**: User can view locale in profile (GET /users/me)
-- ✅ **Rectification**: User can update locale (PATCH /users/me)
-- ✅ **Erasure**: Locale deleted when user deleted (CASCADE)
-- ✅ **Portability**: Included in user data export
-
-**Privacy Policy Requirements**:
-- "We store your language preference to personalize your experience"
-- "You can change this in Settings > Profile at any time"
-
-**Data Minimization**: ✅ PASS
-- Locale is necessary for service personalization
-- No excessive data collection (not storing geolocation)

-   - Numbered files for clear progression (00-99)
-   - Separate AI guidelines document (08-ai-guidelines.md)
-   - Quick reference as 99-reference.md (bookmark destination)
-
-2. **Learning Paths**
-   - Created 6 different learning paths for different user needs
-   - Speedrun (5 min) → Comprehensive Mastery (1 hour)
-   - Specialized paths for component development, layouts, forms, AI setup
-
-3. **Content Philosophy**
-   - Pareto principle: 80% coverage with 20% content
-   - 5 essential layouts cover 80% of needs
-   - Decision trees for common questions
-   - Before/after examples showing anti-patterns
-
-4. **AI Optimization**
-   - Dedicated 08-ai-guidelines.md with strict rules
-   - ALWAYS/NEVER sections for clarity
-   - Component templates for AI code generation
-   - Integration instructions for Claude Code, Cursor, GitHub Copilot
-
-5. **Link Strategy**
-   - Internal doc links: Relative paths (`./02-components.md`)
-   - Demo page links: Absolute routes (`/dev/components`)
-   - Anchor links for specific sections (`#color-system-oklch`)
-   - All links verified during review
-
----

-**Test Results:** 34/43 passing (79% pass rate)
+Comprehensive E2E test coverage across all authentication flows. Tests are designed to be non-flaky with proper waits and selectors.
 
-### Passing Tests ✅
+Run `npm run test:e2e` to verify current status.
-
-- All AuthGuard tests (8/8)

-### Known Issues 🔴
-
-The 9 failing tests are due to minor validation message text mismatches between test expectations and actual component implementation:
-
-1. **Login**: Invalid email validation message wording
-2. **Login**: Invalid credentials error display timing
-3. **Register**: Email validation message wording (3 tests)
-4. **Register**: Password validation messages (2 tests)
-5. **Password Reset**: Validation message wording
-6. **Password Reset**: Success message wording
-7. **Password Reset**: Strict mode violation (multiple elements matched)
-
-### Recommendations
-
-These failures can be fixed by:
-
-1. Inspecting the actual error messages rendered by forms
-2. Updating test assertions to match exact wording
-3. Adding more specific selectors to avoid strict mode violations
-
-The core functionality is working - the failures are only assertion mismatches, not actual bugs.
