+# HealthBridge
+
+Intelligente Health-Daten-Synchronisation für iOS – Eine "Single Source of Truth" für Gesundheitsdaten.
+
+## Übersicht
+
+HealthBridge liest alle Quellen aus Apple Health, erkennt Konflikte zwischen verschiedenen Geräten und Apps, merged intelligent basierend auf konfigurierbaren Regeln und schreibt bereinigte Daten zurück.
+
+## Features
+
+### Source Discovery
+- Automatische Erkennung aller verbundenen Datenquellen
+- Klassifizierung nach Gerätetyp (iPhone, Apple Watch, Drittanbieter-Watch, Apps)
+- Übersicht über Fähigkeiten und unterstützte Datentypen pro Quelle
+
+### Konflikt-Erkennung
+- Automatische Erkennung von Datenkonflikten zwischen Quellen
+- Zeitfenster-basierte Analyse (15-Minuten-Intervalle)
+- Schweregrad-Klassifizierung (minor, moderate, significant, major)
+
+### Merge-Strategien
+- **Exclusive**: Nur eine Quelle möglich (z.B. Blutdruck, SpO2)
+- **Priority**: Fixe Rangfolge basierend auf Benutzereinstellungen
+- **Higher Wins**: Grösserer Wert gewinnt (ideal für Schritte)
+- **Coverage**: Quelle mit Daten für Zeitfenster gewinnt
+- **Coverage Then Higher**: Erst Abdeckung, dann höherer Wert
+- **Average**: Durchschnitt aller Quellen
+- **Manual**: Benutzer entscheidet bei jedem Konflikt
+
+### UI-Komponenten
+- **Dashboard**: Tagesübersicht aller Gesundheitsdaten mit Sync-Status
+- **Konflikte**: Liste offener Konflikte mit One-Tap-Auflösung
+- **Regeln**: Konfiguration der Merge-Strategien pro Datentyp
+- **Quellen**: Übersicht aller erkannten Datenquellen
+
+### Background Sync
+- Automatische Synchronisierung im Hintergrund
+- Konfigurierbares Intervall (15 Min bis 2 Stunden)
+- Push-Benachrichtigungen bei neuen Konflikten
+
+## Unterstützte Datentypen
+
+| Datentyp | Primärquelle | Strategie |
+|----------|--------------|-----------|
+| Schritte | Watch | Coverage + Higher |
+| Herzfrequenz | Watch | Exclusive |
+| Blutdruck | Watch D2 | Exclusive |
+| SpO2 | Watch | Exclusive |
+| Schlaf | Watch | Priority |
+| Distanz | Watch/iPhone | Coverage + Higher |
+| Stockwerke | iPhone | Exclusive |
+| Aktive Energie | Watch | Coverage + Higher |

+```
+
+## Änderungen in index.php
+
+### 1. Am Anfang der Datei (nach den requires)
+
+```php
+<?php
+// ... bestehende requires ...
+
+// NEU: Settings Manager einbinden
+require_once 'SettingsManager.php';
+$settingsManager = new SettingsManager();
+
+// AJAX-Handler für Settings (VOR session_start!)
+$settingsManager->handleAjax();
+```
+
+### 2. Im HEAD-Bereich (CSS einbinden)
+
+```html
+<link rel="stylesheet" href="css/player-controls.css">
+```
+
+### 3. Vor </body> (JavaScript einbinden)
+
+```html
+<script src="js/timelapse-controls.js"></script>
+<script src="js/video-player.js"></script>
+<?php if ($adminManager->isAdmin()): ?>
+<script src="js/admin-settings.js"></script>
+<?php endif; ?>
+```
+
+### 4. Video-Container anpassen
+
+Ersetze den bestehenden video-container:
+
+```html
+<div class="video-container">
+    <?php echo $webcamManager->displayWebcam(); ?>
+
+    <!-- Timelapse Overlay -->
+    <div id="timelapse-viewer" style="display: none;">
+        <img id="timelapse-image" src="" alt="Timelapse">
+    </div>
+
+    <!-- NEU: Daily Video Player (wird dynamisch befüllt) -->
+</div>
+
+<!-- NEU: Timelapse Controls (außerhalb des Containers) -->
+<div id="timelapse-controls"></div>
+```
+
+### 5. Zuschauer-Anzeige konditionell machen
+
+Ersetze die Viewer-Stat Anzeige:
+
+```php
+<?php
+$viewerCount = $viewerCounter->getInitialCount();
+$showViewers = $settingsManager->shouldShowViewers($viewerCount);
+?>
+
+<?php if ($showViewers): ?>
+<div class="info-badge viewer-stat">
+    <span class="live-dot"></span>
+    <strong id="viewer-count-display"><?php echo $viewerCount; ?></strong>
+    <span>Zuschauer</span>
+</div>
+<?php endif; ?>
+```
+
+### 6. Kalender Links anpassen
+
+In der `VisualCalendarManager::displayVisualCalendar()` Methode:
+
+```php
+// Für Tagesvideos
+$playInPlayer = $settingsManager->shouldPlayInPlayer();
+$allowDownload = $settingsManager->shouldAllowDownload();
+
+if ($playInPlayer) {
+    // Im Player abspielen
+    $output .= '<a href="#" onclick="DailyVideoPlayer.playVideo(\'' . $video['path'] . '\', ' . ($allowDownload ? 'true' : 'false') . '); return false;" class="play-link">';
+    $output .= '▶️ Abspielen';
+    $output .= '</a>';
+}
+
+if ($allowDownload) {
+    // Download Link
+    $output .= '<a href="?download_specific_video=..." class="download-link">⬇️ Download</a>';
+}
+```
+
+### 7. Admin-Panel erweitern
+
+Füge im Admin-Bereich hinzu:
+
+```php
+<?php if ($adminManager->isAdmin()): ?>
+<section id="admin" class="section">
+    <div class="container">
+        <h2>Admin-Bereich</h2>
+
+        <!-- NEU: Settings Panel -->

+        <?php echo $adminManager->displayAdminContent(); ?>
+    </div>
+</section>
+<?php endif; ?>
+```
+
+### 8. Timelapse Button Event anpassen
+
+Im bestehenden JavaScript:
+
+```javascript
+timelapseButton.addEventListener('click', function(e) {
+    e.preventDefault();
+
+    if (timelapseViewer.style.display === 'none') {
+        // NEU: TimelapseController verwenden
+        TimelapseController.init(imageFiles);
+        TimelapseController.show();
+        timelapseButton.textContent = 'Zurück zur Live-Webcam';
+    } else {
+        TimelapseController.backToLive();
+    }
+});
+```
+
+### 9. Viewer Heartbeat anpassen
+
+Im JavaScript für den Viewer-Counter:
+
+```javascript
+function updateViewerCount() {
+    fetch(window.location.href, {
+        method: 'POST',
+        body: new URLSearchParams({action: 'viewer_heartbeat'})
+    })
+    .then(r => r.json())
+    .then(data => {
+        const display = document.getElementById('viewer-count-display');
+        const container = document.querySelector('.viewer-stat');
+
+        if (data.count && display) {
+            display.textContent = data.count;
+
+            // Mindestanzahl prüfen (aus Settings)
+            const minViewers = window.minViewersToShow || 1;
+            if (container) {
+                container.style.display = data.count >= minViewers ? 'inline-flex' : 'none';
+            }
+        }
+    });
+}
+```
+
+## Fertig!
+
+Nach diesen Änderungen hast du:
+- ✅ Timelapse mit Slider und 1x/10x/100x Geschwindigkeit
+- ✅ Rückwärts-Spulen im Timelapse
+- ✅ Tagesvideos im Player abspielen statt nur Download
+- ✅ "Zurück zu Live" Button
+- ✅ Admin-Einstellungen für Zuschauer-Anzeige
+- ✅ Mindestanzahl für Zuschauer-Anzeige
+- ✅ Video-Modus wählbar (Player/Download)
+- ✅ Alles ohne Seiten-Reload

+# DCTP - Delta Code Transfer Protocol
+
+Du generierst Code im DCTP-Format fuer effiziente Uebertragung.
+
+## Regeln
+
+1. **Zeilennummern am Ende jeder Zeile** im passenden Kommentar-Format
+2. **Immer mit ###FILE: beginnen** bei jedem Codeblock
+3. **Bei Korrekturen NUR die geaenderten Zeilen senden**, nie den ganzen File
+
+## Zeilennummern-Format
+
+- Python/Shell: `code  #Z1`
+- JavaScript/Java/C/C++: `code  //Z1`
+- HTML: `code  <!--Z1-->`
+- CSS: `code  /*Z1*/`
+- SQL: `code  --Z1`
+
+## Befehle
+
+| Befehl | Syntax | Beschreibung |
+|--------|--------|--------------|
+| `###FILE:` | `###FILE:pfad/datei.ext` | Datei angeben |
+| `###NEW` | | Neue Datei, kompletter Inhalt folgt |
+| `###DELETE:` | `###DELETE:Z5-Z12` | Zeilen 5-12 loeschen |
+| `###INSERT_AFTER:` | `###INSERT_AFTER:Z5` | Nach Zeile 5 einfuegen |
+| `###REPLACE:` | `###REPLACE:Z5-Z8` | Zeilen 5-8 ersetzen |
+| `###END` | | Ende des Blocks |
+| `###RENUMBER` | | Zeilennummern neu berechnen |
+| `###CHECKSUM:` | `###CHECKSUM:a3f2b8c1` | Optional: Hash zur Validierung |
+
+## Beispiel: Neue Datei
+
+```
+###FILE:src/calculator.py
+###NEW
+def add(a, b):  #Z1
+    return a + b  #Z2
+  #Z3
+def multiply(a, b):  #Z4
+    return a * b  #Z5
+###END
+```
+
+## Beispiel: Korrektur (REPLACE)
+
+```
+###FILE:src/calculator.py
+###REPLACE:Z4-Z5
+def multiply(a, b):  #Z4
+    """Multipliziert zwei Zahlen."""  #Z5
+    return a * b  #Z6
+###END
+###RENUMBER
+```
+
+## Beispiel: Zeilen einfuegen
+
+```
+###FILE:src/calculator.py
+###INSERT_AFTER:Z2
+  #Z3
+def subtract(a, b):  #Z4
+    return a - b  #Z5
+###END
+###RENUMBER
+```
+
+## Beispiel: Zeilen loeschen
+
+```
+###FILE:src/calculator.py
+###DELETE:Z10-Z15
+###RENUMBER
+```
+
+## Beispiel: Mehrere Dateien
+
+```
+###FILE:src/models/user.py
+###NEW
+class User:  #Z1
+    def __init__(self, name: str):  #Z2
+        self.name = name  #Z3
+###END
+
+###FILE:src/models/order.py
+###NEW
+from .user import User  #Z1
+  #Z2
+class Order:  #Z3
+    def __init__(self, user: User):  #Z4
+        self.user = user  #Z5
+###END
+```
+
+## Wichtig
+
+- Bei Korrekturen: NUR Delta senden, nie kompletten File
+- Nach INSERT/DELETE/REPLACE immer ###RENUMBER
+- Leerzeilen auch nummerieren
+- Zeilennummern werden beim Schreiben automatisch entfernt

+# DCTP - Delta Code Transfer Protocol
+
+Ein Tool um KI-generierten Code effizient in lokale Dateien zu uebertragen. Statt bei jeder Korrektur den kompletten Code neu zu senden, werden nur Aenderungen (Deltas) uebertragen.
+
+## Das Problem
+
+Claude generiert 500 Zeilen Code. Eine kleine Korrektur = nochmal 500 Zeilen. Verschwendung.
+
+## Die Loesung
+
+Zeilennummerierter Code + Steueranweisungen fuer gezielte Aenderungen.
+
+## Installation
+
+```bash
+# Requirements installieren
+pip install -r requirements.txt
+
+# GUI starten
+python dctp_gui.py
+```
+
+## Schnellstart
+
+### 1. Projektverzeichnis waehlen
+
+Klicke auf "Waehlen" und waehle dein Projektverzeichnis.
+
+### 2. KI-Output einfuegen
+
+Kopiere den DCTP-formatierten Output aus deinem Claude-Chat in das Input-Feld.
+
+### 3. Analysieren
+
+Klicke "Analysieren" um eine Vorschau der Operationen zu sehen.
+
+### 4. Ausfuehren
+
+Klicke "Ausfuehren" um die Aenderungen auf deine Dateien anzuwenden.
+
+## DCTP-Format
+
+### Neue Datei erstellen
+
+```
+###FILE:src/calculator.py
+###NEW
+def add(a, b):  #Z1
+    return a + b  #Z2
+###END
+```
+
+### Zeilen ersetzen
+
+```
+###FILE:src/calculator.py
+###REPLACE:Z1-Z2
+def add(a: int, b: int) -> int:  #Z1
+    """Addiert zwei Zahlen."""  #Z2
+    return a + b  #Z3
+###END
+###RENUMBER
+```
+
+### Zeilen einfuegen
+
+```
+###FILE:src/calculator.py
+###INSERT_AFTER:Z2
+  #Z3
+def subtract(a, b):  #Z4
+    return a - b  #Z5
+###END
+###RENUMBER
+```
+
+### Zeilen loeschen
+
+```
+###FILE:src/calculator.py
+###DELETE:Z10-Z15
+###RENUMBER
+```
+
+## Zeilennummern-Format
+
+Die Zeilennummern werden automatisch entsprechend der Programmiersprache formatiert:
+
+| Sprache | Format | Beispiel |
+|---------|--------|----------|
+| Python | `#Z1` | `code  #Z1` |
+| JavaScript | `//Z1` | `code  //Z1` |
+| HTML | `<!--Z1-->` | `code  <!--Z1-->` |
+| CSS | `/*Z1*/` | `code  /*Z1*/` |
+| SQL | `--Z1` | `code  --Z1` |
+
+## Befehle
+
+| Befehl | Beschreibung |
+|--------|--------------|
+| `###FILE:pfad` | Zieldatei angeben |
+| `###NEW` | Neue Datei erstellen |
+| `###DELETE:Z5-Z12` | Zeilen loeschen |
+| `###INSERT_AFTER:Z5` | Nach Zeile einfuegen |
+| `###REPLACE:Z5-Z8` | Zeilen ersetzen |
+| `###END` | Block beenden |
+| `###RENUMBER` | Zeilennummern aktualisieren |
+| `###CHECKSUM:hash` | Datei-Hash validieren |
+
+## Features
+
+- **Vorschau**: Zeigt was passieren wird, bevor es ausgefuehrt wird
+- **Diff-Ansicht**: Zeigt Aenderungen farbig markiert (alt vs neu)
+- **Undo**: Stellt den letzten Zustand wieder her
+- **Backup**: Automatische Backups vor jeder Aenderung
+- **Multi-File**: Mehrere Dateien in einem Durchgang bearbeiten
+- **Checksum**: Optionale Validierung gegen externe Aenderungen
+
+## Einstellungen
+
+- **Projektpfad**: Standard-Projektverzeichnis
+- **Backup-Verzeichnis**: Wo Backups gespeichert werden
+- **Auto-Renumber**: Zeilennummern automatisch aktualisieren
+- **Checksum-Validierung**: Externe Aenderungen erkennen
+- **Theme**: Hell oder dunkel
+
+## Claude-Integration
+
+Kopiere den Inhalt von `CLAUDE.md` in deine Claude-Chats (als Custom Instructions oder am Anfang des Gespraechs), damit Claude im DCTP-Format antwortet.
