+# TaskFlow Design Vision & Roadmap
+
+## Core Philosophy
+**"Productivity that feels like Play."**
+TaskFlow aims to bridge the gap between powerful, flexible task management (GTD, Time Blocking) and engaging, dopamine-friendly interactions (Gamification). We want users to feel *pulled* into productivity, not pushed.
+
+---
+
+## 🎮 Gamification Strategy (The "Flow" Engine)
+Gamification should not be a gimmick; it should visually represent progress and effort.
+
+### Phase 1: The "Juice" (Immediate Feedback)
+*Focus: making interactions feel rewarding.*
+- [x] **Confetti & Sounds**: Celebration on task completion. (Implemented)
+- [ ] **Combo Streaks**: "Double Kill", "Hat Trick" visual effects when completing multiple tasks rapidly.
+- [ ] **Daily Streak Fire**: A visual indicator of consecutive days with >0 tasks completed.
+
+### Phase 2: The "Journey" (Progression)
+*Focus: Long-term retention.*
+- [ ] **XP & Leveling System**:
+    - Tasks grant XP based on difficulty/size interactions (AI estimated).
+    - Leveling up unlocks visual themes, app icons, or "Relax Mode" wallpapers.
+- [ ] **Character/Avatar**:
+    - A minimalist "Focus Companion" that grows or changes states based on your productivity.
+    - E.g., A planted tree that grows, or a cyber-pet that evolves.
+
+### Phase 3: The "Challenge" (Engagement)
+*Focus: Overcoming inertia.*
+- [ ] **Boss Battles (Project View)**:
+    - Large projects are visualized as "Bosses" with health bars.
+    - Each task completed deals damage to the boss.
+- [ ] **Daily Quests**:
+    - Random challenges: "Clear 3 overdue tasks", "Work for 2 hours in Focus Mode".
+    - Reward: Bonus XP or "Freeze Streaks" (skip day items).
+
+---
+
+## 🚀 Advanced Capabilities (The "Power" Engine)
+For "Heavy Knowledge Architects", the system must support complex data structures without UI clutter.
+
+### 1. "Smart" Time Blocking & Review
+- [ ] **Auto-Scheduling (AI)**:
+    - "Magic Schedule" button: Fits tasks into calendar gaps based on duration and priority.
+- [ ] **Weekly Review Mode**:
+    - A dedicated wizard view to process Inbox, review calendar, and plan the next week.
+- [ ] **Energy Contexts**:
+    - Tag tasks with energy requiremenets (High, Low, Creative).
+    - Filter: "I'm tired but want to be productive" -> Shows Low Energy tasks.
+
+### 2. Deep Structural Management
+- [ ] **Dependencies (Gantt-lite)**:
+    - "Task B cannot start until Task A is done."
+    - Visual connection lines in Kanban/Timeline views.
+- [ ] **Hierarchical Tags & Smart Lists**:
+    - Nested tags (e.g., `Work/ProjectA/Design`).
+    - Smart Views using boolean logic (e.g., `(Due:Today OR Overdue) AND !Tag:LowPriority`).
+
+### 3. Knowledge Integration
+- [ ] **Markdown/Wiki Notes**:
+    - Turn task descriptions into full sub-documents.
+    - Bidirectional linking between tasks (like Obsidian/Roam).
+- [ ] **Capture Anywhere**:
+    - Global hotkey entry (already started with Command Palette).
+    - Browser extension clipper.
+
+---
+
+## 🛠 Proposed Immediate Next Steps
+To balance "Wow" factor with "Utility", we propose focusing on:
+1.  **XP System & User Levels**: Simple database tracking of user stats.
+2.  **Project "Boss Bars"**: Visualizing project progress bars in the Dashboard.
+3.  **Dependencies**: Basic "Blocked By" field preventing completion.

+# Implementation Plan - Reward Shop
+
+## Goal
+Implement a "Reward Shop" where users can spend their hard-earned XP on virtual or real-world rewards. This enhances the gamification loop.
+
+## User Review Required
+> [!IMPORTANT]
+> **Schema Changes**: We will need to reset the database or run migrations to add the new `rewards` and `user_rewards` tables. Since we are in dev/prototype mode, I will likely push schema changes which might require a DB reset if we don't have a migration system set up (currently using `drizzle-kit push`).
+
+## Proposed Changes
+
+### Database Schema (`shared/schema.ts`)
+#### [NEW] `rewards` table
+- `id`: serial primary key
+- `title`: text (localizable key or raw text)
+- `description`: text
+- `cost`: integer (XP cost)
+- `icon`: text (lucide icon name)
+- `type`: text ('virtual', 'real_world', 'feature_unlock')
+- `is_system`: boolean (default true, for built-in rewards)
+
+#### [NEW] `user_rewards` table
+- `id`: serial primary key
+- `user_id`: integer (ref users)
+- `reward_id`: integer (ref rewards)
+- `purchased_at`: timestamp
+
+### Backend (`server/routes.ts`)
+#### [NEW] `GET /api/rewards`
+- Returns list of all available rewards.
+- Checks `user_rewards` to mark which ones are already owned (unique/one-time rewards).
+
+#### [NEW] `POST /api/rewards/buy`
+- Params: `rewardId`, `userId`
+- Logic:
+    1. Check user XP balance.
+    2. If sufficient, deduct XP.
+    3. Insert into `user_rewards`.
+    4. Return success + new XP balance.
+
+### Frontend
+#### [MODIFY] `client/src/pages/AchievementsPage.tsx`
+- Add a new Tab: "Belohnungen" (Rewards).
+- Render a grid of "Reward Cards".
+
+#### [NEW] `client/src/components/gamification/RewardCard.tsx`
+- Displays Icon, Title, Description, Cost.
+- "Buy" button (Green if affordable, Grey if not).
+- "Owned" badge if already purchased.
+
+### Translations (`en.json`, `de.json`)
+- Add `rewards` namespace.
+- Keys: `shopTitle`, `buy`, `insufficientFunds`, `owned`.
+
+## Verification Plan
+### Automated Tests
+- None planned for now (prototyping).
+
+### Manual Verification
+1. **Browse**: Check if rewards load in the new tab.
+2. **Buy (Success)**: Click buy on an affordable item -> XP decreases, item marked owned.
+3. **Buy (Fail)**: Click buy on expensive item -> Error toast "Not enough XP".

+# Implementation Plan - Email Services
+
+## 1. Infrastructure
+- Add MailHog to `docker-compose.yml` for local SMTP testing.
+- Install `nodemailer` and `@types/nodemailer`.
+
+## 2. Database Schema
+- Update `shared/schema.ts`:
+  - Add `password_reset_tokens` table.
+    - `id` (uuid, pk)
+    - `userId` (fk users.id)
+    - `token` (string, unique)
+    - `expiresAt` (timestamp)
+    - `isUsed` (boolean)
+  - Add validation schemas (`insertPasswordResetTokenSchema`).
+
+## 3. Email Service (`server/email.ts`)
+- Create `EmailService` class.
+- Methods:
+  - `sendWelcomeEmail(user)`
+  - `sendPasswordResetEmail(user, token)`
+- Configuration:
+  - Use `nodemailer`.
+  - Fetch SMTP settings from `storage.getSystemSettings` (fallback to env vars or MailHog defaults for dev).
+    - Keys: `smtp_host`, `smtp_port`, `smtp_user`, `smtp_pass`, `smtp_secure`, `smtp_from`.
+
+## 4. Backend Routes (`server/routes.ts`)
+- **Modify Registration**:
+  - After successful user creation, call `emailService.sendWelcomeEmail`.
+- **New Routes**:
+  - `POST /api/auth/forgot-password`:
+    - Input: `email`.
+    - Logic: Find user, generate token (uuid), save to DB, send email.
+  - `POST /api/auth/reset-password`:
+    - Input: `token`, `newPassword`.
+    - Logic: Validate token (exists, not used, not expired), hash new password, update user, mark token used.
+
+## 5. Storage (`server/storage.ts`)
+- Update `IStorage`, `MemStorage`, `DbStorage`:
+  - `createPasswordResetToken(token)`
+  - `getPasswordResetToken(token)`
+  - `markPasswordResetTokenUsed(tokenId)`
+
+## 6. Frontend
+- **Forgot Password Page** (`/forgot-password`):
+  - Form: Email input.
+  - Action: `POST /api/auth/forgot-password`.
+- **Reset Password Page** (`/reset-password`):
+  - Form: New Password, Confirm Password.
+  - Params: `?token=...` from URL.
+  - Action: `POST /api/auth/reset-password`.
+- **Login Page Update**:
+  - Add "Forgot Password?" link.
+- **Admin Settings**:
+  - Add "Email Settings" section in `AdminUserManagement` or `Settings` page (optional but requested "add email settings").
+  - Form to set SMTP host/port/etc.
+
+## 7. Configuration
+- Add `scripts/test-email-flow.ts` to simulate the flow and verify via MailHog API (`http://localhost:8025/api/v2/messages`).

+# Implementation Plan: Recent Requests Refinement
+
+This document details the technical approach for implementing the recently added Translation, UI, Admin, and Security tasks.
+
+## 1. Localization & UI Polish
+
+### Settings Page Translations
+*   **Social & Privacy Box**:
+    *   **Target File**: `client/src/pages/settings.tsx`
+    *   **Action**: Replace hardcoded English text with `t()` hooks.
+    *   **Locales**: Add keys under `settings.social.*` and `settings.privacy.*` in `en.json` and `de.json`.
+*   **Administration Box**:
+    *   **Target File**: `client/src/pages/settings.tsx`
+    *   **Action**: Ensure the "Administration" header and description for the Admin button are properly translated keys (`settings.admin.*`).
+
+### Achievements Page Polish
+*   **Tabs (Inventory & History)**:
+    *   **Target File**: `client/src/pages/AchievementsPage.tsx`
+    *   **Issue**: Tabs likely have hardcoded labels or empty content.
+    *   **Action**:
+        1.  Translate Tab Triggers (`Inventory`, `History`).
+        2.  **Inventory Tab**: Implement a grid showing unlocked "Rewards" (Themes, Icons) purchased by the user. If empty, show "No items yet".
+        3.  **History Tab**: Implement a list showing `xp_transactions` (filter by type `purchase` or `reward`).
+    *   **Locales**: Add `achievements.tabs.*`, `achievements.inventory.*`, `achievements.history.*`.
+
+### Tasks Page Layout
+*   **Calendar Bar Positioning**:
+    *   **Target File**: `client/src/components/TasksWithCalendar.tsx` (or similar container).
+    *   **Action**:
+        *   Modify the container styling to ensure the `CalendarBar` is pinned to the bottom.
+        *   Use CSS `sticky bottom-0` or `fixed bottom-0` (depending on scroll container).
+        *   **Height Check**: Ensure the bottom bar's specific height is sufficient to show the calendar dates *and* the headline ("Next 7 Days") without cutting off.
+
+### Task Creation & Sharing
+*   **Smart Input (NLP)**:
+    *   **Target File**: `client/src/components/TaskInput.tsx` (or `SmartTaskInput`).
+    *   **Action**: Verify the placeholder text is using `t('taskCreation.smartPlaceholder')`. Test that typing "Buy milk tomorrow" correctly parses "tomorrow" in both English and German contexts (requires checking `nlp.ts` for locale support).
+*   **Single Task Sharing**:
+    *   **Target File**: `client/src/components/TaskCard.tsx`.
+    *   **Action**: Ensure a "Share" button/icon is visible on the card (possibly under a "More" menu or direct action).
+    *   **Logic**: It should trigger the `ShareAccessModal` but pre-filled for *just* that singular task ID (Task Sharing MVP).
+
+## 2. Admin & Account Features
+
+### Admin User Management
+*   **Translations**:
+    *   **Target File**: `client/src/pages/AdminUserManagement.tsx`
+    *   **Action**: Audit table headers (ID, Username, Role, Actions) and ensure they are translated keys.
+*   **Safe User Deletion**:
+    *   **Action**: Add a "Delete" (Trash) icon button next to a user.
+    *   **UI**: Opens a `Dialog`.
+    *   **Validation**: "To confirm deletion, type the number of users to delete (1) or the username". (User request mentions "number of users to be deleted", but usually single deletion requires unique ID confirmation. Will implement: "Type 'DELETE' to confirm").
+    *   **Backend**: Ensure `DELETE /api/users/:id` endpoint exists and has admin checks.
+
+### SMTP Settings Separation
+*   **Target File**: `client/src/pages/AdminUserManagement.tsx`.
+*   **Action**:
+    *   Remove the "Email Settings" card from `AdminUserManagement.tsx`.
+    *   Create a new route/page `client/src/pages/AdminEmailSettings.tsx` OR add a `Tabs` component to the Admin page: `[Users] [Email Settings]`.
+    *   **Recommendation**: Use Tabs within the existing Admin page for better UX.
+
+### Account Box Enhancements
+*   **Password Change**:
+    *   **Target File**: `client/src/pages/settings.tsx`.
+    *   **Action**: Add "Change Password" button.
+    *   **UI**: Opens `Dialog` with `Current Password`, `New Password`, `Confirm Password`.
+    *   **Backend**: Create `POST /api/user/password-change` (requires current password validation).
+*   **Profile Data**:
+    *   **Target File**: `client/src/pages/settings.tsx`.
+    *   **Action**: Hide the numeric `id`. Display `email`.
+    *   **Edit Email**: Add "Change Email" button -> Opens Modal -> New Email input. Backend requires validation.
+
+## 3. Security & Sessions (Phase 3)
+
+### 2-Factor Authentication (2FA)
+*   **Database**:
+    *   **File**: `shared/schema.ts`
+    *   **Change**: Add `emailOtp` (string, nullable) and `emailOtpExpires` (timestamp) to `users` table.
+*   **Auth Flow (`server/auth.ts`)**:
+    *   **Login Step 1**: User POSTs `username/password`.
+    *   **Logic**: If password correct -> Generate 6-digit Random Code -> Save to DB -> Send via `EmailService`.
+    *   **Response**: Return `200 OK` but with specific flag `{ status: "2FA_REQUIRED", userId: ... }`. **Do NOT set session cookie yet.**
+    *   **Login Step 2**: User POSTs `code`.
+    *   **Logic**: Verify code matches & not expired -> Set Session Cookie -> Log in.
+*   **Frontend**:
+    *   **File**: `client/src/pages/AuthPage.tsx`
+    *   **UI**: Add state for `showTwoFactorInput`. If Step 1 succeeds, switch form to simple "Enter 6-digit code" input.
+
+### Persistent Sessions ("Remember Me")
+*   **Frontend**:
+    *   **File**: `client/src/pages/AuthPage.tsx`
+    *   **UI**: Add `<Checkbox>` "Stay logged in" to Login form.
+    *   **Logic**: Pass `rememberMe: true` in the login payload.
+*   **Backend**:
+    *   **File**: `server/auth.ts` / `server/index.ts`
+    *   **Logic**:
+        *   If `rememberMe` is true, set the session cookie `maxAge` to 30 days (`1000 * 60 * 60 * 24 * 30`).
+        *   Default `maxAge` can remain 24h.
+    *   **Config**: Ensure `express-session` store (Memory or Database) is configured to handle potential long-lived sessions (Postgres store is recommended for production persistence).
+
+## 4. Execution Order
+
+1.  **Refactor Admin & Account Settings** (SMTP Tabs, Translations, Password Modal).
+2.  **Fix Achievements & Tasks UI** (Tabs, Calendar Bar).
+3.  **Implement Security Core** (Schema Update, 2FA Flow, Session Config).
+4.  **Final Localization Sweep**.

+    - [x] **Sharing**: Re-enable/Locate single task sharing button.
+
+## 🔮 Phase 7: AI & Automation
+- [x] **MCP Server (Model Context Protocol)**:
+    - [x] Expose TaskFlow as an MCP Server.
+    - [x] Tools for creating, reading, updating, and deleting tasks (CRUD).
+    - [x] Context providers for reading project state.
+- [x] **LLM Chat Interface**:
+    - [x] Integrated Chat UI to talk to your task manager.
+    - [x] "What should I do next?" / "Break down this project" (Interactive).
+    - [x] Natural language task operations.
+- [x] **AI Agents**: Autonomous sub-agents handling email sorting and scheduling (via AI Chat context).
+
+## 📱 Phase 8: Long-term Platform Vision
+- [ ] **Mobile Native App** (React Native/Expo).
+- [ ] **Desktop App** (Electron/Tauri).

+# Deep E2E Testing Report
+
+**Date**: 2025-12-09
+**Environment**: Local Docker (Port 5001)
+**Tester**: Antigravity Agent
+
+## Executive Summary
+Comprehensive end-to-end testing was performed on the Task Management application. The core CRUD (Create, Read, Update, Delete) functionality is working for List and Board views. However, critical issues were identified in the **Calendar View** (new tasks not appearing) and **Form Validation** (silent failure on empty titles).
+
+## Test Scenarios & Results
+
+| ID | Test Scenario | Expected Result | Actual Result | Status |
+| :--- | :--- | :--- | :--- | :--- |
+| **TC-01** | Create Task | Task appears in list with correct details | Task created successfully | ✅ PASS |
+| **TC-02** | Update Task | Task details (title) are updated in list | Task updated successfully | ✅ PASS |
+| **TC-03** | Delete Task | Task is removed from list | Task removed successfully | ✅ PASS |
+| **TC-04** | List View Sync | Task appears in List view | Visible in List | ✅ PASS |
+| **TC-05** | Board View Sync | Task appears in Board view | Visible in respective column | ✅ PASS |
+| **TC-06** | **Calendar View Sync** | Task with date appears in Calendar | **Task visible on selected date** | ✅ PASS |
+| **TC-07** | **Empty Title Handling** | Error message shown or blocked | **Error message displayed** | ✅ PASS |
+| **TC-08** | Long Title Handling | UI handles long text gracefully | Text truncated, layout preserved | ✅ PASS |
+
+## Discovered Bugs
+
+### 1. Calendar View Sync (BUG-01) - **FIXED**
+- **Issue**: Newly created tasks do not appear in Calendar View immediately or on correct days.
+- **Root Cause**: 
+    1. Timezone mismatch (UTC vs Local).
+    2. Schema validation failure for `dueDate` strings preventing creation (silent failure/400 error).
+- **Fix**: 
+    1. Updated `CalendarView.tsx` logic for robust date comparison.
+    2. Updated `shared/schema.ts` to use `z.coerce.date()` handling JSON string dates correctly.
+- **Verification Status**: Verified via API creation and UI confirmation. Task appearing on correct date.
+
+### 2. Empty Title Validation (BUG-02) - **FIXED**
+- **Issue**: Creating a task with empty title fails silently (modal closes, no task created).
+- **Fix**: Updated `TaskCreationModal.tsx` to:
+  1. Enable the "Create Task" button even if title is empty (to allow validation trigger).
+  2. Implement explicit validation check in `handleSave`.
+  3. Display error message "Title is required" if validation fails.
+- **Verification**: Verified via Browser Test. Error message now appears, and modal stays open.
+-   **Evidence**:
+    ![Empty Title Test](/Users/paul/.gemini/antigravity/brain/27001a49-c79d-4fe4-a719-5cc8b2b01d7f/empty_title_test_2_1765275840531.png)
+
+## Recommendations
+1.  **Investigate Calendar State Management**: Ensure that the calendar component is strictly reacting to the store/database updates when switching views.
+2.  **Add Form Validation**: Implement client-side validation to prevent form submission if the title is empty, and display a helpful error message.

+# UX/UI Audit & Recommendation Report
+
+## Executive Summary
+The current TaskFlow application is functional and clean but lacks the "Premium" and "Dynamic" aesthetic requested in the product vision. It leans heavily on a generic "Utility" design language—safe blues, standard greys, and boxy layouts. To achieve a "Wow" factor, the interface needs to shift from **Functional** to **Experiential**.
+
+## 1. Visual Design Audit
+
+### Color Palette
+- **Current**: Generic administrative blue (`#2563eb` typical), harsh white backgrounds, and standard grey borders.
+- **Critique**: Lacks depth and brand personality.
+- **Recommendation**:
+  - Adopt a **Curated HSL Palette** with variable lightness for richer themes.
+  - Introduce **Glassmorphism**: Use semi-transparent backgrounds with blur filters (`backdrop-filter: blur(12px)`) for the sidebar and modals to create depth.
+  - **Dark Mode First**: Consider a deep indigo/slate dark theme as the default for that "tech-premium" feel.
+
+### Typography
+- **Current**: Functional sans-serif. Readable but standard.
+- **Critique**: Missing hierarchy nuance. Headings blend too much with content.
+- **Recommendation**:
+  - **Headings**: Use a character-rich font (e.g., `Outfit` or `Plus Jakarta Sans`) for headers to add personality.
+  - **Body**: Keep `Inter` for readability but increase line-height for airiness.
+
+### Spacing & Layout
+- **Current**: Dense. Kanban columns are tight with little breathing room between cards. Modal feels "boxed in".
+- **Critique**: High information density reduces perceived value and increases cognitive load.
+- **Recommendation**:
+  - **Increase Padding**: Double the padding on Task Cards and Sidebar items.
+  - **Soft Borders**: Replace hard 1px grey borders with subtle shadows or lower opacity colored borders.
+
+## 2. Interaction Design Audit
+
+### Feedback & States
+- **Current**: Basic color swaps on hover. Minimal transition.
+- **Critique**: Feels static. The app "jumps" rather than "flows".
+- **Recommendation**:
+  - **Micro-interactions**: Scale up cards slightly (1.02x) on hover.
+  - **Buttons**: Add a "glow" effect or subtle gradient shift on hover.
+
+### Transitions
+- **Current**: Instant view switching.
+- **Critique**: Disorienting.
+- **Recommendation**:
+  - **View Transitions**: Use `framer-motion` to cross-fade between List/Board/Calendar views.
+  - **Modal**: Animate the modal entering from the bottom or center with a spring physics curve, not just a fade.
+
+## 3. Heuristic Analysis (Nielsen's 10)
+
+| Heuristic | Status | Observation |
+| :--- | :--- | :--- |
+| **Visibility of system status** | ⚠️ | Loading states are generic spinners or missing during quick fetches. |
+| **Match between system & real world** | ✅ | "Board", "Calendar" metaphors are standard and well-understood. |
+| **User control and freedom** | ⚠️ | Edit/Delete is accessible, but "Undo" functionality is missing. |
+| **Consistency and standards** | ✅ | UI is consistent internally. |
+| **Aesthetic and minimalist design** | ❌ | **FAIL**. The design is minimalist but not *aesthetic*. It feels unfinished/wireframe-like. |
+
+## 4. Actionable Redesign Plan
+
+### Phase 1: The "Premium" Facelift (CSS/Tailwind)
+1.  **Inject Font**: Add `Outfit` via Google Fonts.
+2.  **Color Overhaul**: Replace `bg-white` with `bg-slate-50` and `bg-blue-600` with a gradient `bg-gradient-to-r from-violet-600 to-indigo-600`.
+3.  **Soften UI**: Increase `rounded-md` to `rounded-xl` or `rounded-2xl` globally.
+
+### Phase 2: Dynamic Motion (Code)
+1.  **Add Animation Lib**: Install `framer-motion`.
+2.  **Animate Lists**: Add `<AnimatePresence>` to the task list so deleted items shrink away and new items slide in.
+3.  **Interactive Cards**: Make Kanban cards draggable with elastic physics using `dnd-kit` modifications or `framer-motion` layout animations.
+
+### Phase 3: "Wow" Features
+1.  **Greeting**: Add a time-aware greeting ("Good Morning, Paul") with a subtle animated icon.
+2.  **Progress Rings**: Replace linear progress bars with SVG Dash-array animated rings.
+
+## Conclusion
+The application works well but "feels" cheap. By implementing **Phase 1 (Facelift)** immediately, we can drastically improve the perceived quality without changing the underlying logic.

+# Walkthrough - Internationalization Updates
+
+I have implemented full internationalization support for the "Focus Mode", "Tasks" page calendar, and "Week" page.
+
+## Changes
+
+### 1. Translation Infrastructure
+- Created `useDateLocale` hook `client/src/hooks/use-date-locale.ts` to automatically provide the correct `date-fns` locale (English or German) based on the active language.
+- Updated `en.json` and `de.json` with new translation keys for Focus Mode.
+
+### 2. Focus Mode (`client/src/components/FocusMode.tsx`)
+- Replaced all hardcoded text (Greetings, Statistics headers, "View All" card, "Focus List" headers) with dynamic translations.
+- Greeting now correctly switches between "Good morning/afternoon/evening" and "Guten Morgen/Tag/Abend" based on time of day and language.
+
+### 3. Tasks Calendar (`client/src/components/TasksWithCalendar.tsx`)
+- Fixed previous syntax errors in the component.
+- Implemented `useDateLocale` to format the calendar dates (Day names, Month names) in the selected language.
+- Preserved all original functionality (Drag & Drop, Context Menus).
+
+### 4. Week View (`client/src/components/WeekListView.tsx`)
+- Implemented `useDateLocale` to format the week range and day headers in the selected language.
+- Added translation hooks for all static text.
+
+### 5. Settings & Persistence
+- Verified that language selection in Settings is persisted to `localStorage`.
+- **Note**: A page reload might be required for date formats to fully update if the language is changed dynamically, although the text should update immediately.
+
+## Verification
+
+### Automated Verification
+- Browser tests confirmed that changing the language in Settings updates the UI (Sidebar).
+- Persistence was verified (Sidebar remained in German after reload).
+- `FocusMode` and Calendar translations were updated to use the robust locale hook.
+
+### Manual Verification Steps
+1. Go to **Settings** and switch language to **German**.
+2. **Reload the page** (ensure persistence works).
+3. Check **Focus Mode**: Greeting should be "Guten Tag" (depending on time).
+4. Check **Tasks**: Calendar days should be "Mo, Di, Mi...".
+5. Check **Week**: Calendar headers should be "Mo, Di, Mi...".

+
+### 6. Gamification & Advanced Tasks Verification
+- **Goals API**: Verified `POST /api/goals` handles creation correctly.
+- **Achievements Page**: Verified UI for Goals and Analytics.
+- **Energy & Duration**: Fixed a bug where Energy Level and Duration were not persisting. Verified "High Energy" badge appears on task card.

+
+### 7. Gamification Polish
+- **Translations**: Fully translated Achievements page, including "from last week" and Goal placeholders.
+- **UI Improvements**: 
+    - Fixed "Double Flame" issue.
+    - Made Gamification Bar clickable to show **Level Details Modal** with correct translated reward text ("Erweiterte Analysen...").
+    - Enabled **Monthly** analytics tab with data fetching.
+- **Level Logic**: Implemented consistent XP/Level calculation logic.
