-🛡️ UNCOMPROMISING PRIVACY & SECURITY 

- No data collection. No compromises.
- • 100% Anonymous: Zero tracking, zero analytics, zero telemetry.
- • Ready Out-Of-The-Box: No technical knowledge needed. Install and start watching immediately using the official public server.
- • RAM-Only Public Server: The official relay server operates entirely in volatile RAM. No databases, no logs, no watch history — nothing persists. It also features built-in rate-limiting and brute-force protection to prevent room-id spamming.
- • Self-Hostable: Take total control by deploying a private relay server in seconds via Docker. Optional, never required.

-🚀 HOW IT WORKS 
+🛡️ PRIVACY & SECURITY
+KoalaSync is built for private watch parties without unnecessary data collection.

- 1. Install KoalaSync and click "Create Room" to spin up a secure lobby.
- 2. Copy the invite link and send it to your friends.
- 3. Open your favorite streaming site and set the video tab as the active target.
- 4. Press play — everyone stays perfectly in sync.
+• No Tracking: Zero analytics, zero telemetry, and absolutely no behavior profiling.
+• Anonymous by Design: No accounts needed. Rooms can be joined with a simple nickname.
+• Ready Out of the Box: Install KoalaSync and start watching immediately using the official public relay server. No technical setup required.
+• RAM-Only Public Server: The official relay server operates entirely in volatile RAM. No databases, no stored watch history, no persistent room data. Room data exists only temporarily and disappears when the room closes.
+• Self-Hostable: Want full control? You can run your own private KoalaSync relay server via Docker in seconds. Self-hosting is optional and never required.

+⚙️ UNDER THE HOOD
+KoalaSync is lightweight, transparent, and built with privacy in mind.
+
+• Real-Time Relay: Playback state is synchronized through a custom WebSocket-based relay server for fast room updates.
+• No Media Streaming: KoalaSync does not stream, proxy, upload, download, or redistribute any video content. Everyone watches from their own browser on the original website.
+• Temporary Room State Only: The relay server only coordinates room state such as play, pause, seek position, active target, nickname, and readiness status.
+• Docker Self-Hosting: The relay server can be self-hosted with Docker if you prefer to run your own private instance.
+• Open Architecture: The project is designed to be inspectable, forkable, and easy to review.

- **Automated Injection**: The build script (`node scripts/build-extension.js`) automatically injects `EVENTS` and `HEARTBEAT_INTERVAL` into `content.js` using marker-based replacement (see `scripts/README.md` for marker details).

+## [v2.3.2] — 2026-06-16
+
+### Changed
+- **Extension: Refined Spanish, Italian, and Portuguese translations**: Complete manual review and improvement of all Spanish (`es`), Italian (`it`), Portuguese — Brazil (`pt-BR`), and Portuguese — Portugal (`pt`) locale files for both the extension UI and the landing website. Thanks to [@Kaia-Alenia](https://github.com/Kaia-Alenia) for the native-quality translations.
+
+### Fixed
+- **Extension: Locale typos and corrupted characters fixed**: Repaired a Korean refresh button label (`Refreschi` → `새로고침`), a corrupted Korean connection status string (`연kel` → `연결`), a Korean character contaminating a Japanese string (`의` → `の`), and a Dutch typo (`cmmuniceren` → `communiceren`).
+- **Server: Admin token length leak fixed (timing side-channel)**: `isAdminMetricsAuthorized()` returned early when the provided buffer had a different length than the expected token, leaking the token length via response timing. Now `crypto.timingSafeEqual` runs in constant time on every attempt regardless of length match. Reported by [@Kaia-Alenia](https://github.com/Kaia-Alenia).

+
+## [v2.3.1] — 2026-06-15
+
+### Changed
+- **Server: Smart unhandled rejection handling (exits after 5/min instead of 1)**
+- **Server: Optimized admin health metrics allocation**
+
+---
+
+## [v2.3.0] — 2026-06-14
+
+### Added
+- **Extension: New Interactive Onboarding Tour**: A fully redesigned, interactive step-by-step onboarding experience.
+- **Extension: Auto-Switch to Sync Tab**: The UI now intelligently switches to the Sync tab when you join a room to guide video selection.
+- **Extension: Uninstall URL Integration**: Prepared an uninstall URL setup that works natively across Chrome and Firefox, cleanly attaching browser context for analytics.
+
+### Fixed
+- **Extension: Infinite Seek Loop Prevention**: Replaced the fragile time-based seek suppression with an exact target-time verification mechanism, entirely eliminating infinite seek loops on slow buffers.
+- **Extension: Zombie Connections Resolved**: Implemented a forced disconnect upon ping timeouts, ensuring the extension reliably auto-reconnects when the WebSocket hangs in a half-open state.
+- **Extension: Room Switching Architecture**: Joining a new room while already connected now explicitly severs the old connection first, preventing state cross-contamination. 
+- **Extension: Join/Leave Race Conditions**: Added UI locks to prevent users from accidentally sending conflicting connection commands via rapid double-clicking.
+- **Extension: Same-Room Invite Bypass**: Clicking an invite link for the room you are currently in no longer triggers a redundant reconnect, instead instantly confirming the join.
+- **Extension: Audio settings now propagate immediately to video tabs**: Changes made in the audio options page are now instantly applied to the active video tab. Previously, settings saved to `chrome.storage.local` were not picked up by the background listener, which only watched `chrome.storage.sync`.
+- **Extension: Audio compressor now logs enable/disable state and resume failures**: The compressor reports when it is activated or bypassed, and warns if the `AudioContext` cannot be resumed (e.g. browser autoplay policy requires a user gesture on the page first).
+- **Extension: Video heartbeat no longer sent when alone in a room**: The full media metadata `PEER_STATUS` is now only emitted when other peers are present. The session keepalive (background heartbeat) continues to run unaffected, preventing the server reaper from disconnecting idle peers.
+- **Server: Increased `failedAuthAttempts` eviction threshold from 50k to 200k**: Reduces frequency of expensive batch evictions under high auth-failure volumes, smoothing heap usage.
+
+---
+
+## [v2.2.4] — 2026-06-10
+
+### Fixed
+- **Extension: Error notifications now respect `browserNotifications` setting**: Server error events (e.g. "Server is restarting") no longer trigger a browser notification when the user has disabled notifications in the extension settings.
+- **Server: Misleading reconnect message corrected**: The graceful shutdown message no longer tells users to manually reconnect — the extension handles this automatically.
+
+---
+
+## [v2.2.3] — 2026-06-10
+
+### Added
+- **Artifact Attestations (Supply Chain Security)**: All release artifacts (Docker images, extension ZIPs) are now published with signed [SLSA provenance attestations](https://docs.github.com/en/actions/how-tos/secure-your-work/use-artifact-attestations) via `actions/attest@v4`. Anyone can verify that an artifact was built from this repository using `gh attestation verify`.
+- **Admin health: `rateLimits.denied` counters**: New rolling counters track actual rate-limit denials (429 responses), separate from `rateLimits.trackedClients` which reports unique IPs in the tracking window.
+- **Docker HEALTHCHECK**: Container health is now checked every 30s via `GET /health`.
+- **`npm start` script**: Server can now be started with `npm start`.
+
+### Fixed
+- **Server: `activeLobby` no longer silently overwritten**: If a second peer sends `EPISODE_LOBBY` while a lobby is already active, the request is now ignored instead of destroying the first peer's lobby.
+- **CORS log sanitization**: Rejected origin headers are sanitized (`\r\n` stripped) to prevent log injection.
+- **Extension: pagehide resource leak**: `keepAlivePort`, `lobbyPollTimer`, heartbeats, and `MutationObserver` are now properly cleaned up when a tab is hidden or enters bfcache.
+- **Extension: unhandled storage rejections**: `chrome.storage.session.set()` calls in the disconnect handler now have `.catch(() => {})`.
+- **`'Pixel'` duplicate in name generator**: Second occurrence replaced with `'Nitro'` for better name diversity.
+- **`'opposum'` typo**: Corrected to `'opossum'` in the emoji map and added `'Opossum'` to `USERNAME_NOUNS`.
+- **Test reliability**: `test-server-routes.mjs` now sets `ADMIN_METRICS_TOKEN` before importing the server module, fixing standalone test execution.
+- **`MAX_PEERS_PER_ROOM` konsistent**: `.env` auf 25 gesetzt (wie `.env.example`).
+- **pt-BR.json duplicate removed**: Duplicate `FOOTER_DISCLAIMER` key removed from website locale.
+
+### Changed
+- **Admin health: `rateLimitEntries` renamed to `rateLimits.trackedClients`**: The field now accurately describes that it tracks unique clients in the rate-limit window, not denial counts. Update your json_exporter/Grafana config accordingly.
+- **README restructured**: Sections reordered by progressive technical depth. New "Supply Chain Security" subsection under "For Developers & Self-Hosters" with verification commands.
+
+---
+
+## [v2.2.2] — 2026-06-09
+
+### Added
+- **Chrome Web Store i18n Support**: Added `default_locale: "en"` to manifest and created `_locales/*/messages.json` for all 13 supported languages. This unlocks the language selection dropdown in the Chrome Web Store dashboard, allowing translated store listings (title, description) per locale. The extension's own UI translations (`locales/*.json` + `i18n.js`) remain unchanged.
+- **Locale test coverage**: Extended `scripts/test-locales.js` to validate all `_locales/*/messages.json` files (correct format, required keys, no duplicates) and verify `default_locale` is set in the manifest.
+
+### Fixed
+- **Copy Logs button alignment**: Removed stray `margin-top: 8px` inherited from `.secondary` class that pushed the button 8px down in the connection status row.
+
+---
+
+## [v2.2.1] — 2026-06-09
+
+### Added
+- **Server Ping Display**: Measures round-trip latency to the relay server via application-level ping/pong events. The extension sends `PING { t }` every 15 seconds; the server responds with `PONG { t }`. Round-trip time is calculated client-side and displayed in the Status tab, color-coded (<50ms green, 50–150ms yellow, >150ms red). No ping value is shown when disconnected or if the server does not respond within 5 seconds.
+- **Peer Ping Response (Future-Proof)**: The extension can now respond to incoming `PING { t, sender }` events from other peers by sending back `PONG { t, target: sender }`. The relay server forwards `PING` to the target peer and routes `PONG` back to the original sender. Both client and server validate that peers are in the same room before forwarding/routing. Peer-to-peer ping initiation will be activated in a future extension update without requiring a server restart.
+
+---
+
+## [v2.2.0] — 2026-06-08
+
+### Added
+- **Web Audio API Compressor**: Built-in audio dynamic range compression with four presets (Recommended, Dynamic Range, Vocal Enhancement, Smooth) and fully customizable sliders (threshold, ratio, knee, attack, release). Uses dry/wet crossfade (40ms linear ramp) to avoid clicks. Configured via the new Audio Options page accessible from the Settings tab.
+- **Audio Options Page** (`audio-options.html`): Dedicated settings page with master toggle, compressor preset selector, real-time custom sliders, and equalizer placeholder. Dark theme matching the popup design.
+- **Feature Hint System**: Generic `dismissedHints` array in sync storage for announcing new features. First hint highlights the Audio Options entry in Settings. Extensible for future features.
+
+### Changed
+- **Ko-Fi Support Links**: Static footer badges on the Settings and Status tabs linking to the developer's support page. README and website footer updated with Ko-Fi badge.
+
+### Fixed
+- **Portuguese (PT) locale**: Removed Italian contamination — "sincronizzazione" → "sincronização", "tempo reale" → "tempo real", "Link di Invito" → "Link de Convite", "Sair della Sala" → "Sair da Sala".
+- **Korean locale**: Fixed broken character in `HOWTO_STEP_2_TEXT` (`클rip보드` → `클립보드`).
+- **Website COMP_FEAT_6_KOALA**: Normalized from inconsistent "6 Languages" to "13 Languages" across all locale files (en, de, es, fr, pt-BR, ru).
+- **Debug report showing wrong logs**: Fixed `logs.slice(-50)` and `history.slice(-20)` in the "Copy Debug Report" feature. Since `addLog()` and `addToHistory()` use `unshift` (inserting entries at index 0), the arrays are ordered newest-first. `slice(-N)` took the N **oldest** entries instead of the N **newest**. Changed to `slice(0, N).reverse()` to correctly include the most recent logs and display them chronologically.

+## Status Legend

-### 1. Behebung des synchronen Sortierungs-Flaschenhalses bei Auth-Failure LRU-Eviction
-* **Kategorie**: Performance / DoS-Prävention
-* **Hintergrund**: Der Server schützt Räume vor Brute-Force-Angriffen durch die Nachverfolgung fehlerhafter Anmeldeversuche (`failedAuthAttempts` Map). Bei Erreichen des Limits von 50.000 Einträgen wird ein Bereinigungsverfahren gestartet, das die gesamte Map in ein Array konvertiert und dieses per `Array.from().sort()` sortiert.
-* **Problem**: Dies blockiert den Node.js-Main-Thread für mehrere Millisekunden und stellt einen potenziellen Denial-of-Service-Vektor (DoS) dar, wenn ein Angreifer gezielt Fehlversuche spamt.
-* **Geplante Lösung**: 
-  - Umstellung auf eine echte, $O(1)$-basierte LRU-Cache-Datenstruktur (z. B. doppelt verkettete Liste in Kombination mit einer Map).
-  - Alternativ: Ein vereinfachtes zeitbasiertes Ablauf-Verfahren oder ein schrittweises Löschen von Segmenten (Chunk-Eviction), um Blockaden des Main-Threads vollständig auszuschließen.

-### 2. Aufteilung großer JavaScript-Dateien (> 800 Zeilen) in kleinere Module
-* **Kategorie**: Wartbarkeit / AI-Kontext-Optimierung
-* **Hintergrund**: Einige Kern-Dateien wie `background.js` und `popup.js` sind stark angewachsen und überschreiten 800 Zeilen. Dies erschwert das manuelle Debugging und verbraucht unnötig viel Kontextfenster bei AI-Modellen.
-* **Geplante Lösung**: 
-  - Strukturierte Aufteilung der Logik in separate, fokussierte Module (z. B. UI-Renderer, Message-Router, Storage-Manager, Socket-Client).
-  - Nutzung von ES-Modulen zur sauberen Strukturierung und besseren Wiederverwendbarkeit.

+
+## 📋 Planned
+
+*Prioritized for upcoming phases.*
+
+### 1. Split large JavaScript files into smaller modules
+
+- **Priority:** P1
+- **Category:** Maintainability / AI Context Optimization
+- **Background:** Core files like `background.js` and `popup.js` have grown large and exceed 800 lines. This makes manual debugging harder and wastes context window space for AI models.
+- **Planned solution:**
+  - Structurally split logic into separate focused modules (e.g., UI Renderer, Message Router, Storage Manager, Socket Client).
+  - Use ES modules for clean separation and better reusability.
+
+### 2. Invite link with target URL for auto-redirect
+
+- **Priority:** P2
+- **Category:** UX / Ease of Sharing
+- **Background:** The invite link currently only contains the room ID. The invited person has to manually open the page. Ideally, the link would include the shared tab's URL so the invitee gets redirected to the right page and the tab is auto-selected (auto-matching via tab title already exists).
+- **Known challenges:**
+  - Many streaming sites (e.g., Emby, Jellyfin) don't have unique URLs per content — once inside the player, the URL stays the same.
+  - Dozens of such edge cases exist; a generic solution is difficult.
+  - Would likely need site-specific extractor logic (similar to the existing sync service adapters).
+- **Possible approaches:**
+  - Fallback: if no unique URL can be determined, only pass the tab title.
+  - Site-specific URL extraction for known services.
+
+---
+
+## 💡 Backlog
+
+*Ideas and feature requests under evaluation.*
+
+### In-room chat overlay (like TeleParty)
+
+- **Priority:** P3
+- **Category:** Social / Communication
+- **Background:** A collapsible chat panel to the right of the video (or as an overlay) allowing text-based communication with everyone in the room.
+- **Why backlog (still uncertain):**
+  - **Use case:** No strong personal need — with chat, latency matters less than with voice; async communication tolerates a few seconds of delay.
+  - **Complexity:** Relatively large feature (UI + message persistence + possibly history).
+  - **Legal/moderation:** Unclear what moderation requirements would apply if users can exchange chat messages. Could be relevant depending on jurisdiction.
+- **Status:** Under evaluation, may come later.

+# KoalaSync Translation & Localization Guide
+
+Welcome to the **KoalaSync** translation guide! We rely on the open-source community to make KoalaSync accessible to users worldwide.
+
+KoalaSync is split into two independent translation areas. You can translate either one, or both:
+1. **The Browser Extension** (`extension/locales/`): The core product that users interact with daily.
+2. **The Website** (`website/locales/`): The landing page and invitation bridge.
+
+---
+
+## 📊 Supported Languages Dashboard
+
+We divide supported languages into two tiers: **Core Languages** (fully hand-crafted and audited by native speakers) and **Extended Languages** (auto-generated using translation models to expand initial coverage).
+
+> [!TIP]
+> **Help Us Improve!**
+> We welcome community contributions to audit "Auto-Generated" translations and elevate them to "Verified" status.

+
+---
+
+## 🛠️ How to Translate KoalaSync
+
+Here is the exact step-by-step process for contributing translations.
+
+### Step 1: Fork and Clone the Repository
+If you are an external contributor, start with the standard Open Source workflow:
+1. Click the "Fork" button on GitHub to create your own copy of the repository.
+2. Clone your fork locally: `git clone https://github.com/YOUR-USERNAME/KoalaSync.git`
+3. Create a branch: `git checkout -b translation/my-language`
+
+### Step 2: Translate the Extension
+The browser extension handles real-time syncing, settings, and popups.
+1. Navigate to [`extension/locales/`](file:///Users/koala/Documents/Workspaces/KoalaSync/extension/locales/).
+2. Edit an existing `[lang].json` or copy `en.json` to create a new one (e.g., `it.json`).
+3. Translate all the string values. **Do not change the JSON keys.**
+
+### Step 3: Translate the Website
+The website hosts the landing page and invitation bridge.
+1. Navigate to [`website/locales/`](file:///Users/koala/Documents/Workspaces/KoalaSync/website/locales/).
+2. Edit an existing `[lang].json` or copy `en.json` to create a new one.
+3. Translate all the string values. **Do not change the JSON keys.**
+4. If creating a **brand new language**, configure the metadata at the top of your JSON file:
+   ```json
+   {
+     "LANG_CODE": "it",
+     "HTML_CLASS": "lang-it",
+     "CANONICAL_PATH": "it/",
+     "LANG_TOGGLE_URL": "../",
+     "LANG_TOGGLE_TEXT": "EN"
+   }
+   ```
+5. If creating a **brand new language**, register it in `website/build.js` by adding it to the `languages` array.
+
+### Step 4: Verify Locally
+Ensure your JSON files are valid and all keys match the English baseline. Open your terminal in the KoalaSync root folder and run:
+```bash
+# Tests the extension locales for missing keys or syntax errors
+node scripts/test-locales.js
+
+# Tests the website locales for missing keys or syntax errors
+node scripts/test-website-locales.mjs
+
+# Builds the website with your new translations
+node website/build.js
+```
+*Note: If you receive any errors about missing keys or `TODO` placeholders, please fix them before submitting.*
+
+### Step 5: Commit and Pull Request
+1. Open this `TRANSLATION.md` file and add/update your language in the **Supported Languages Dashboard** above. Mark it as `100% Manually Verified` if you are a native speaker.
+2. Commit your changes: `git commit -m "Update Italian translations"`
+3. Push to your fork: `git push origin translation/my-language`
+4. Open a **Pull Request** on the main KoalaSync repository on GitHub.
+

+
+## ⚖️ Strict Legal Exclusion Rule
+
+Our legal pages have strict constraints to protect user privacy and avoid regulatory liabilities.
+
+> [!IMPORTANT]
+> **DO NOT TRANSLATE LEGAL DOCUMENTS**
+> The legal notice ([impressum.html](file:///Users/koala/Documents/Workspaces/KoalaSync/website/impressum.html)) and privacy policy ([datenschutz.html](file:///Users/koala/Documents/Workspaces/KoalaSync/website/datenschutz.html)) **MUST remain exclusively in English and German**.
+> 
+> *   **Rationale:** Legal compliance under the European Union General Data Protection Regulation (GDPR) and the German Digital Services Act (DDG). Offering automated translations of legally binding notices introduces compliance risks due to potential mistranslations of liability limits.
+> *   **Technical Fallback:** Our system automatically falls back to **English** for legal pages if a user visits them in an unsupported language, so you do not need to worry about this.

-# KoalaSync Browser Extension v2.0 - i18n Technical Implementation Plan
-
-Welcome, future Antigravity AI agent! This document is placed directly in the codebase at `/extension/locales/i18n_plan.md` to serve as a comprehensive architectural handbook for the next steps in adding **full internationalization (i18n) support to the browser extension itself** while maintaining 100% video-sync and background communication safety.
-
---
-
-## 🔍 Context & Audited Scope
-
-KoalaSync is a lightweight, premium browser extension (Chrome & Firefox Manifest V3) for synchronized video playback. The landing pages are already compiled dynamically in 6 languages:
-*   English (`en`)
-*   German (`de`)
-*   French (`fr`)
-*   Spanish (`es`)
-*   Portuguese (Brazil) (`pt-BR`)
-*   Russian (`ru`)
-
-Our goal is to build an identical, premium translation engine for the extension itself.
-
---
-
-## 🏛️ Architectural Choice: Custom JSON Dictionary Engine (Approach B)
-
-We evaluated two paths:
-1.  **Approach A (Native `chrome.i18n` API):** Uses `_locales/` directory. Too rigid—cannot support real-time dynamic switching inside the extension Settings dropdown without closing/re-opening the popup.
-2.  **Approach B (Custom Unified JSON Engine):** Uses flat JSON files matching our website files (`"KEY": "Value"`). Dynamically merges the target dictionary with baseline English `en.json` at runtime, programmatically providing an **airtight English fallback** and **real-time DOM translations** without popup reload.
-
-We chose **Approach B** for maximum compatibility, premium real-time toggling, and clean fallback safety.
-
---
-
-## 🔄 Resolve, Load, & State Flow
-
-1.  **On launch:** Look for saved language in `chrome.storage.sync.get('locale')`.
-2.  **Fallback Autodetect:** If no saved language, read `navigator.language` or `chrome.i18n.getUILanguage()`.
-    *   If the detected locale is supported, set as active.
-    *   If not supported, default to English (`en`).
-3.  **Dictionary Resolution:**
-    *   Asynchronously load the English baseline dictionary (`/extension/locales/en.json`).
-    *   If the target language is different, load target JSON (e.g. `/extension/locales/de.json`) and execute `Object.assign({}, enDict, targetDict)`. This guarantees dynamic translation while cleanly falling back to English for any missing keys.
-4.  **DOM Replacements:** Scan for `data-i18n`, `data-i18n-title`, and `data-i18n-placeholder` attributes, and translate them on the fly.
-5.  **Persistence:** Save dynamic selection modifications from the dropdown into `chrome.storage.sync`. Trigger instant DOM re-translation on change.

-
-## 🛠️ Draft Code Snippets
-
-### 1. `i18n.js` (Zero-Dependency Engine Module)
-```javascript
-// extension/i18n.js
-export const SUPPORTED_LANGUAGES = ['en', 'de', 'fr', 'es', 'pt-BR', 'ru'];
-export const DEFAULT_LANGUAGE = 'en';
-
-let activeDictionary = {};
-
-export async function loadLocale(langCode) {
-    const resolvedLang = SUPPORTED_LANGUAGES.includes(langCode) ? langCode : DEFAULT_LANGUAGE;
-    try {
-        const enResponse = await fetch(chrome.runtime.getURL(`locales/${DEFAULT_LANGUAGE}.json`));
-        const enDict = await enResponse.json();
-        
-        if (resolvedLang === DEFAULT_LANGUAGE) {
-            activeDictionary = enDict;
-            return;
-        }
-
-        const targetResponse = await fetch(chrome.runtime.getURL(`locales/${resolvedLang}.json`));
-        const targetDict = await targetResponse.json();
-        
-        activeDictionary = Object.assign({}, enDict, targetDict);
-    } catch (err) {
-        console.error('[i18n] Failed to load dictionary. Falling back to English:', err);
-        const rescue = await fetch(chrome.runtime.getURL(`locales/${DEFAULT_LANGUAGE}.json`));
-        activeDictionary = await rescue.json();
-    }
-}
-
-export function getMessage(key) {
-    return activeDictionary[key] || key;
-}
-
-export function translateDOM() {
-    // Translate text nodes
-    document.querySelectorAll('[data-i18n]').forEach(el => {
-        const key = el.getAttribute('data-i18n');
-        const translated = getMessage(key);
-        const img = el.querySelector('img');
-        if (img) {
-            el.innerHTML = '';
-            el.appendChild(img);
-            el.appendChild(document.createTextNode(' ' + translated));
-        } else {
-            el.textContent = translated;
-        }
-    });
-
-    // Translate tooltips
-    document.querySelectorAll('[data-i18n-title]').forEach(el => {
-        const key = el.getAttribute('data-i18n-title');
-        el.setAttribute('title', getMessage(key));
-    });
-
-    // Translate placeholders
-    document.querySelectorAll('[data-i18n-placeholder]').forEach(el => {
-        const key = el.getAttribute('data-i18n-placeholder');
-        el.setAttribute('placeholder', getMessage(key));
-    });
-}
-```
-
-### 2. Markup Changes (`popup.html`)
-*   Annotate text elements: `<button class="tab-btn" data-tab="tab-settings" data-i18n="TAB_SETTINGS" data-i18n-title="TAB_SETTINGS_TOOLTIP">Settings</button>`
-*   Add Language Dropdown in the Settings Panel:
-    ```html
-    <div class="form-group" style="display: flex; align-items: center; justify-content: space-between; background: var(--card); padding: 10px; border-radius: 8px; margin-bottom: 12px; border: 1px solid #334155;">
-        <label style="margin-bottom: 0;" data-i18n="LABEL_LANGUAGE" title="Choose your preferred extension language">App Language</label>
-        <select id="langSelector" style="width: 150px; padding: 6px 10px; font-size: 13px; cursor: pointer;">
-            <option value="en">English</option>
-            <option value="de">Deutsch</option>
-            <option value="fr">Français</option>
-            <option value="es">Español</option>
-            <option value="pt-BR">Português (Brasil)</option>
-            <option value="ru">Русский</option>
-        </select>
-    </div>
-    ```
-
-### 3. Dynamic Script Wiring (`popup.js`)
-*   Import our engine: `import { loadLocale, translateDOM, getMessage } from './i18n.js';`
-*   Initialize during startup:
-    ```javascript
-    async function init() {
-        const data = await chrome.storage.sync.get(['locale', ...]);
-        let activeLang = data.locale;
-        if (!activeLang) {
-            const systemLang = (navigator.language || chrome.i18n.getUILanguage()).split('-')[0];
-            activeLang = ['en', 'de', 'fr', 'es', 'pt', 'ru'].includes(systemLang) ? (systemLang === 'pt' ? 'pt-BR' : systemLang) : 'en';
-            chrome.storage.sync.set({ locale: activeLang });
-        }
-        await loadLocale(activeLang);
-        translateDOM();
-        
-        // Select matching option in selector
-        const langSelector = document.getElementById('langSelector');
-        if (langSelector) langSelector.value = activeLang;
-        
-        // rest of standard init...
-    }
-    ```
-*   Listen to Settings change event:
-    ```javascript
-    const langSelector = document.getElementById('langSelector');
-    if (langSelector) {
-        langSelector.addEventListener('change', async () => {
-            const selectedLang = langSelector.value;
-            await chrome.storage.sync.set({ locale: selectedLang });
-            await loadLocale(selectedLang);
-            translateDOM();
-            // Re-render empty elements and tab list using new dynamic strings
-            refreshLogs();
-            refreshHistory();
-            populateTabs();
-        });
-    }
-    ```
-
-### 4. Background Notifications (`background.js`)
-*   Notifications inside `showNotification` should fetch dynamic keys based on `chrome.storage.sync` language settings and build clean alerts dynamically using `chrome.storage.sync.get('locale')`.
-*   Ensure that WebSocket event transmissions and video player scripts in `content.js` remain **completely untouched and unaware** of the localization engine.
-
---
-
-## 🔒 Safety Guardrail
-
-*   **WebSocket Engine Integrity:** Under no circumstances should `background.js` Socket.IO handshakes, rate limits, or binary protocol headers be adjusted. i18n is strictly an interface rendering skin layer.
-*   **Player Control Pipeline Integrity:** `content.js` expectedEvent suppression tables, HLS buffer calculations, and Media Session API listeners must remain untouched. Do not bind any i18n logic into the content script's active tracking loop.
-
---
-
-## 🧪 Verification Tasks
-
-1.  **Autodetection Audit:** Force-load the extension in Chrome/Firefox in a non-English language container and ensure it starts in that language or English gracefully.
-2.  **Integrity Validation Script:** Write a sanity node checker script `/scripts/test-locales.js` to ensure all key structures are uniform across all JSON files.
-3.  **Real-Time Refresh Verification:** Change dynamic drop-down preferences and verify that every element and alert swaps languages cleanly with zero redraw glitches or page crashes.

-# KoalaSync Translation & Localization Guide
-
-Welcome to the **KoalaSync** translation and internationalization framework! This document provides clear, professional instructions for developers and contributors looking to maintain, audit, or add new languages to the official KoalaSync website.
-
---
-
-## 🏛️ Architecture Overview
-
-The KoalaSync website utilizes a custom, high-performance, zero-dependency static site generator built in Node.js. Instead of using complex client-side translation runtimes or bulky frameworks, localized pages are compiled ahead-of-time (AOT) to maintain lightning-fast page speeds and strict data sovereignty.
-
-*   **Template Source:** [`website/template.html`](file:///Users/koala/Documents/KoalaPlay/website/template.html) (Single Source of Truth)
-*   **Locales Source:** `/website/locales/[lang].json` (Structured JSON translation dictionaries)
-*   **Build Pipeline:** [`website/build.js`](file:///Users/koala/Documents/KoalaPlay/website/build.js) (Pure Node.js script that compiles pages into `/website/www/`)
-
---
-
-## 📊 Supported Languages Dashboard
-
-We divide supported languages into two tiers: **Core Languages** (fully hand-crafted and audited by native speakers) and **Extended Languages** (auto-generated using translation models to expand initial coverage).
-
-> [!TIP]
-> **Help Us Improve!**
-> We welcome community contributions to audit "Auto-Generated" translations and elevate them to "Verified" status.
-
-| Language Code | Language Name | Verification Status | Rationale / Context |
-| :--- | :--- | :--- | :--- |
-| `en` | 🇬🇧 **English** | `100% Manually Verified` | Primary developer language and system default |
-| `de` | 🇩🇪 **German** | `100% Manually Verified` | Core market and compliance baseline |
-| `fr` | 🇫🇷 **French** | `Auto-Generated` | Needs manual native review and polishing |
-| `es` | 🇪🇸 **Spanish** | `Auto-Generated` | Needs manual native review and polishing |
-| `pt-BR` | 🇧🇷 **Portuguese (Brasil)** | `Auto-Generated` | Needs manual native review and polishing |
-| `ru` | 🇷🇺 **Russian** | `Auto-Generated` | Needs manual native review and polishing |
-| `it` | 🇮🇹 **Italian** | `Auto-Generated` | Needs manual native review and polishing |
-| `pl` | 🇵🇱 **Polish** | `Auto-Generated` | Needs manual native review and polishing |
-| `tr` | 🇹🇷 **Turkish** | `Auto-Generated` | Needs manual native review and polishing |

-| `ko` | 🇰🇷 **Korean** | `Auto-Generated` | Needs manual native review and polishing |
-| `pt` | 🇵🇹 **European Portuguese** | `Auto-Generated` | Needs manual native review and polishing |
-
-> [!WARNING]
-> **Autogeneration Quality Rule**
-> Any newly contributed languages must be committed as `"Auto-Generated"` until fully reviewed and signed off by a native speaker in a pull request.

-## ⚖️ Strict Legal Exclusion Rule
-
-Our legal pages have strict constraints to protect user privacy and avoid regulatory liabilities.
-
-> [!IMPORTANT]
-> **DO NOT TRANSLATE LEGAL DOCUMENTS**
-> The legal notice ([impressum.html](file:///Users/koala/Documents/KoalaPlay/website/impressum.html)) and privacy policy ([datenschutz.html](file:///Users/koala/Documents/KoalaPlay/website/datenschutz.html)) **MUST remain exclusively in English and German**.
-> 
-> *   **Rationale:** Legal compliance under the European Union General Data Protection Regulation (GDPR) and the German Digital Services Act (DDG). Offering automated translations of legally binding notices introduces compliance risks due to potential mistranslations of liability limits.
-> *   **Technical Fallback:** The dynamic initializer script (`lang-init.js`) is configured to automatically fallback to **English** for legal pages if a user visits them with a French, Spanish, or other unsupported language preference, keeping their dynamic dropdown choice intact for homepage links.

-
-## 🛠️ Step-by-Step: Adding a New Language
-
-Adding a new language (e.g., Italian - `it`) is straightforward. Follow these four structured steps:
-
-### Step 1: Create the Translation Dictionary
-Create a new JSON file inside the locales directory named `[lang].json` (e.g., `website/locales/it.json`).
-1. Copy the structure of [`website/locales/en.json`](file:///Users/koala/Documents/KoalaPlay/website/locales/en.json) to use as your baseline.
-2. Translate all string values while keeping the JSON keys identical.
-3. Configure the language metadata keys at the top of the file:
-   ```json
-   {
-     "LANG_CODE": "it",
-     "HTML_CLASS": "lang-it",
-     "CANONICAL_PATH": "it/",
-     "LANG_TOGGLE_URL": "../",
-     "LANG_TOGGLE_TEXT": "EN"
-   }
-   ```
-
-### Step 2: Register in the Compiler
-Open the static site generator script [`website/build.js`](file:///Users/koala/Documents/KoalaPlay/website/build.js) and append your new language code to the active `languages` array:
-```javascript
-// Add 'it' to the array
-const languages = ['en', 'de', 'fr', 'es', 'pt-BR', 'ru', 'it'];
-```
-
-### Step 3: Run the Build Script
-Execute the compiler from the root of the repository:
-```bash
-node website/build.js
-```
-The compiler will automatically:
-1. Load the new JSON translation file.
-2. Create the target subdirectory `/website/www/it/`.
-3. Generate the compiled `/website/www/it/index.html` landing page, injecting correct relative assets and canonical metadata.
-
-### Step 4: Update the Dashboard
-Open this `TRANSLATION.md` file and add your language to the **Supported Languages Dashboard** table, marking it as `Auto-Generated` (unless manually verified).

-
-## 🔮 Future Roadmap: Dynamic Utility Pages
-
-For pages that require fully dynamic, client-side interactions (like the room invitation bridge [`join.html`](file:///Users/koala/Documents/KoalaPlay/website/join.html)), we need to scale to unlimited languages without bloating the HTML size or polluting the URL.
-
-### Clean Client-Side i18n Architecture
-
-To maintain zero URL pollution (e.g. keeping invitation links clean as `/join.html#join:roomID:password`), we propose an **asynchronous JSON dictionary injection architecture**:
-
-#### 1. Page Lifecycle Flow
-1. **User Landing:** The guest enters `/join.html` with a shared hash.
-2. **Language Resolution:** `lang-init.js` immediately reads their saved preference (`localStorage` or `navigator.language`) and applies the active class (e.g. `html.lang = "es"`).
-3. **Async Fetching:** A client-side loader script (`i18n-client.js`) runs asynchronously, downloading the correct dictionary (`fetch("/locales/es.json")`).
-4. **DOM Translation:** The script scans the page for elements carrying a `data-i18n` attribute and safely updates their text content at runtime, avoiding dual-text nodes and stylesheet recalculations.
-
-#### 2. Declarative HTML Markup
-Elements are defined with custom data attributes specifying translation keys. English text is placed as the static HTML fallback:
-```html
-<h1 data-i18n="JOIN_TITLE">Ready to sync?</h1>
-<p id="join-desc" data-i18n="JOIN_SUBTITLE">You've been invited to join a session.</p>
-```
-
-#### 3. Zero-Dependency Engine (`i18n-client.js`)
-```javascript
-document.addEventListener('DOMContentLoaded', async () => {
-    // 1. Recover the language determined during early initialization
-    const activeLang = document.documentElement.lang || 'en';
-    if (activeLang === 'en') return; // Default markup is already in English
-    
-    // 2. Fetch the corresponding locale JSON asynchronously
-    try {
-        const response = await fetch(`locales/${activeLang}.json`);
-        if (!response.ok) throw new Error('Locale file unavailable');
-        const dictionary = await response.json();
-        
-        // 3. Scan and translate data-i18n attributes
-        document.querySelectorAll('[data-i18n]').forEach(el => {
-            const key = el.getAttribute('data-i18n');
-            if (dictionary[key]) {
-                if (el.tagName === 'IMG') {
-                    el.alt = dictionary[key];
-                } else {
-                    el.textContent = dictionary[key];
-                }
-            }
-        });
-    } catch (err) {
-        console.warn('Dynamic i18n loading failed. Defaulting to English:', err);
-    }
-});
-```
-
-#### Core Benefits
-*   **Zero URL Pollution:** Keeps invitation hashes private and avoids messy query parameters (`?lang=de`), protecting user privacy.
-*   **Optimal Performance:** Eliminates duplicate hidden text blocks, cutting page weight in half and ensuring smooth rendering.
-*   **Infinite Scale:** Adding new languages to dynamic pages requires zero edits to HTML markup; the engine simply fetches new JSON dictionaries on-demand.

-In **v2.0**, we extended full internationalization support to the **Browser Extension itself**. The architecture mirrors our web-based dynamic localization model to maintain complete parity.
-
-*   **Locales Directory:** [`extension/locales/`](file:///Users/koala/Documents/KoalaPlay/extension/locales/)
-*   **Active Dictionaries:**
-    *   [`en.json`](file:///Users/koala/Documents/KoalaPlay/extension/locales/en.json) (🇬🇧 Baseline English)
-    *   [`de.json`](file:///Users/koala/Documents/KoalaPlay/extension/locales/de.json) (🇩🇪 German)
-    *   [`fr.json`](file:///Users/koala/Documents/KoalaPlay/extension/locales/fr.json) (🇫🇷 French)
-    *   [`es.json`](file:///Users/koala/Documents/KoalaPlay/extension/locales/es.json) (🇪🇸 Spanish)
-    *   [`pt-BR.json`](file:///Users/koala/Documents/KoalaPlay/extension/locales/pt-BR.json) (🇧🇷 Portuguese (Brasil))
-    *   [`ru.json`](file:///Users/koala/Documents/KoalaPlay/extension/locales/ru.json) (🇷🇺 Russian)
-    *   [`it.json`](file:///Users/koala/Documents/KoalaPlay/extension/locales/it.json) (🇮🇹 Italian)
-    *   [`pl.json`](file:///Users/koala/Documents/KoalaPlay/extension/locales/pl.json) (🇵🇱 Polish)
-    *   [`tr.json`](file:///Users/koala/Documents/KoalaPlay/extension/locales/tr.json) (🇹🇷 Turkish)
-    *   [`nl.json`](file:///Users/koala/Documents/KoalaPlay/extension/locales/nl.json) (🇳🇱 Dutch)
-    *   [`ja.json`](file:///Users/koala/Documents/KoalaPlay/extension/locales/ja.json) (🇯🇵 Japanese)
-    *   [`ko.json`](file:///Users/koala/Documents/KoalaPlay/extension/locales/ko.json) (🇰🇷 Korean)
-    *   [`pt.json`](file:///Users/koala/Documents/KoalaPlay/extension/locales/pt.json) (🇵🇹 European Portuguese)
-*   **Translation Engine:** [`extension/i18n.js`](file:///Users/koala/Documents/KoalaPlay/extension/i18n.js)
-*   **Validation Script:** [`scripts/test-locales.js`](file:///Users/koala/Documents/KoalaPlay/scripts/test-locales.js)
-
-### ⚙️ How it Works inside the Extension
-
-1. **System Locale Auto-Detection**: On first run, the extension detects the browser system language using `navigator.language` or `chrome.i18n.getUILanguage()`.
-2. **On-the-Fly Redraws**: When the user selects a different language in the settings tab (`#langSelector`), the selection is stored in `chrome.storage.sync` and the translation engine immediately triggers `translateDOM()`. The interface, empty state cards, tooltips, dynamic onboarding tutorial guides, and status badges re-render instantly without reloading the popup.
-3. **Localized System Notifications**: On play, pause, or seek commands, `background.js` retrieves the user's active locale preference from storage, loads the correct dictionary, and pushes native OS notifications fully translated.
-
-### 🧪 Auditing & Sync Checks
-
-To ensure that no language dictionary falls out of sync (causing missing labels or blank interfaces), developers must run the locale auditor tool before packaging releases:
-```bash
-node scripts/test-locales.js
-```
-This script asserts that all JSON dictionary files under `extension/locales/` share exactly the same set of keys as the English baseline (`en.json`).

KoalaDev	dd8eefe3f9	fix(security): actually prevent timing leak — eagerly evaluate timingSafeEqual The previous fix had a subtle bug: JavaScript && short-circuits, so crypto.timingSafeEqual() was skipped when buffer lengths differed (sameLength was false). The dummy buffer was allocated but never compared, leaving the original length-based timing leak intact. Now timingSafeEqual is eagerly assigned to a const before the && guard, guaranteeing it runs in constant time on every auth attempt regardless of whether the length guess was correct.	2026-06-16 04:23:20 +02:00
KoalaDev	cc97e0d371	fix(security): prevent admin token length leak via timing side-channel isAdminMetricsAuthorized() returned early when buffer lengths differed, allowing an attacker to discover the token length by measuring response time. Now always calls crypto.timingSafeEqual (using a zeroed dummy buffer on length mismatch) so every auth attempt takes constant time regardless of whether the length guess was correct.
