WIP: Debug backup file discovery system - Fixed recursive directory search in CapacitorPlatformService to properly search subdirectories instead of excluding them - Added missing listFilesInDirectory method to all platform services for directory browsing functionality - Added debug methods (debugTimeSafariDirectory, createTestBackupFile, testDirectoryContexts) to help diagnose file visibility issues - Enhanced logging for backup file discovery process - Current issue: TimeSafari directory exists in Download but shows 'Directory does not exist' when trying to read contents - Need to investigate why JSON backup files are not being found despite directory existence

+# TimeSafari Contact Backup System
+
+## Overview
+
+The TimeSafari application implements a comprehensive contact backup and listing system that works across multiple platforms (Web, iOS, Android, Desktop). This document breaks down how contacts are saved, exported, and listed as backups.
+
+## Architecture Components
+
+### 1. Database Layer
+
+#### Contact Data Structure
+```typescript
+interface Contact {
+  did: string;                    // Decentralized Identifier (primary key)
+  contactMethods?: ContactMethod[]; // Array of contact methods (EMAIL, SMS, etc.)
+  name?: string;                  // Display name
+  nextPubKeyHashB64?: string;     // Base64 hash of next public key
+  notes?: string;                 // User notes
+  profileImageUrl?: string;       // Profile image URL
+  publicKeyBase64?: string;       // Base64 encoded public key
+  seesMe?: boolean;               // Visibility setting
+  registered?: boolean;           // Registration status
+}
+
+interface ContactMethod {
+  label: string;                  // Display label
+  type: string;                   // Type (EMAIL, SMS, WHATSAPP, etc.)
+  value: string;                  // Contact value
+}
+```
+
+#### Database Schema
+```sql
+CREATE TABLE contacts (
+  id INTEGER PRIMARY KEY AUTOINCREMENT,
+  did TEXT NOT NULL,              -- Decentralized Identifier
+  name TEXT,                      -- Display name
+  contactMethods TEXT,            -- JSON string of contact methods
+  nextPubKeyHashB64 TEXT,         -- Next public key hash
+  notes TEXT,                     -- User notes
+  profileImageUrl TEXT,           -- Profile image URL
+  publicKeyBase64 TEXT,           -- Public key
+  seesMe BOOLEAN,                 -- Visibility flag
+  registered BOOLEAN              -- Registration status
+);
+
+CREATE INDEX idx_contacts_did ON contacts(did);
+CREATE INDEX idx_contacts_name ON contacts(name);
+```
+
+### 2. Contact Saving Operations
+
+#### A. Adding New Contacts
+
+**1. QR Code Scanning (`ContactQRScanFullView.vue`)**
+```typescript
+async addNewContact(contact: Contact) {
+  // Check for existing contact
+  const existingContacts = await platformService.dbQuery(
+    "SELECT * FROM contacts WHERE did = ?", [contact.did]
+  );
+  
+  if (existingContact) {
+    // Handle duplicate
+    return;
+  }
+  
+  // Convert contactMethods to JSON string for storage
+  contact.contactMethods = JSON.stringify(
+    parseJsonField(contact.contactMethods, [])
+  );
+  
+  // Insert into database
+  const { sql, params } = databaseUtil.generateInsertStatement(
+    contact as unknown as Record<string, unknown>, "contacts"
+  );
+  await platformService.dbExec(sql, params);
+}
+```
+
+**2. Manual Contact Addition (`ContactsView.vue`)**
+```typescript
+private async addContact(newContact: Contact) {
+  // Validate DID format
+  if (!isDid(newContact.did)) {
+    throw new Error("Invalid DID format");
+  }
+  
+  // Generate and execute INSERT statement
+  const { sql, params } = databaseUtil.generateInsertStatement(
+    newContact as unknown as Record<string, unknown>, "contacts"
+  );
+  await platformService.dbExec(sql, params);
+}
+```
+
+**3. Contact Import (`ContactImportView.vue`)**
+```typescript
+async importContacts() {
+  for (const contact of selectedContacts) {
+    const contactToStore = contactToDbRecord(contact);
+    
+    if (existingContact) {
+      // Update existing contact
+      const { sql, params } = databaseUtil.generateUpdateStatement(
+        contactToStore, "contacts", "did = ?", [contact.did]
+      );
+      await platformService.dbExec(sql, params);
+    } else {
+      // Add new contact
+      const { sql, params } = databaseUtil.generateInsertStatement(
+        contactToStore, "contacts"
+      );
+      await platformService.dbExec(sql, params);
+    }
+  }
+}
+```
+
+#### B. Updating Existing Contacts
+
+**Contact Editing (`ContactEditView.vue`)**
+```typescript
+async saveEdit() {
+  // Normalize contact methods
+  const contactMethods = this.contactMethods.map(method => ({
+    ...method,
+    type: method.type.toUpperCase()
+  }));
+  
+  // Update database
+  const contactMethodsString = JSON.stringify(contactMethods);
+  await platformService.dbExec(
+    "UPDATE contacts SET name = ?, notes = ?, contactMethods = ? WHERE did = ?",
+    [this.contactName, this.contactNotes, contactMethodsString, this.contact?.did]
+  );
+}
+```
+
+### 3. Contact Export/Backup System
+
+#### A. Export Process (`DataExportSection.vue`)
+
+#### 1. Data Retrieval
+
+```typescript
+async exportDatabase() {
+  // Query all contacts from database
+  const result = await platformService.dbQuery("SELECT * FROM contacts");
+  const allContacts = databaseUtil.mapQueryResultToValues(result) as Contact[];
+  
+  // Convert to export format
+  const exportData = contactsToExportJson(allContacts);
+  const jsonStr = JSON.stringify(exportData, null, 2);
+}
+```
+
+#### 2. Export Format Conversion (`libs/util.ts`)
+
+```typescript
+export const contactsToExportJson = (contacts: Contact[]): DatabaseExport => {
+  const rows = contacts.map((contact) => ({
+    did: contact.did,
+    name: contact.name || null,
+    contactMethods: contact.contactMethods 
+      ? JSON.stringify(parseJsonField(contact.contactMethods, []))
+      : null,
+    nextPubKeyHashB64: contact.nextPubKeyHashB64 || null,
+    notes: contact.notes || null,
+    profileImageUrl: contact.profileImageUrl || null,
+    publicKeyBase64: contact.publicKeyBase64 || null,
+    seesMe: contact.seesMe || false,
+    registered: contact.registered || false,
+  }));
+
+  return {
+    data: {
+      data: [{ tableName: "contacts", rows }]
+    }
+  };
+};
+```
+
+#### 3. File Generation
+
+```typescript
+// Create timestamped filename
+const timestamp = getTimestampForFilename();
+const fileName = `${AppString.APP_NAME_NO_SPACES}-backup-contacts-${timestamp}.json`;
+
+// Create blob and save
+const blob = new Blob([jsonStr], { type: "application/json" });
+```
+
+#### B. Platform-Specific File Saving
+
+##### 1. Web Platform (`WebPlatformService.ts`)**
+
+```typescript
+// Uses browser download API
+const downloadUrl = URL.createObjectURL(blob);
+const downloadAnchor = this.$refs.downloadLink as HTMLAnchorElement;
+downloadAnchor.href = downloadUrl;
+downloadAnchor.download = fileName;
+downloadAnchor.click();
+```
+
+##### 2. Mobile Platforms (`CapacitorPlatformService.ts`)
+
+```typescript
+async writeAndShareFile(fileName: string, content: string, options = {}) {
+  let fileUri: string;
+  
+  if (options.allowLocationSelection) {
+    // User chooses location
+    fileUri = await this.saveWithUserChoice(fileName, content, options.mimeType);
+  } else if (options.saveToPrivateStorage) {
+    // Save to app-private storage
+    const result = await Filesystem.writeFile({
+      path: fileName,
+      data: content,
+      directory: Directory.Data,
+      encoding: Encoding.UTF8,
+      recursive: true,
+    });
+    fileUri = result.uri;
+  } else {
+    // Save to user-accessible location (Downloads/Documents)
+    fileUri = await this.saveToDownloads(fileName, content);
+  }
+  
+  // Share the file
+  return await this.shareFile(fileUri, fileName);
+}
+```
+
+##### 3. Desktop Platforms (`ElectronPlatformService.ts`, `PyWebViewPlatformService.ts`)
+
+```typescript
+// Not implemented - returns empty results
+async listBackupFiles(): Promise<Array<{name: string, uri: string, size?: number, type: 'contacts' | 'seed' | 'other', path?: string}>> {
+  return [];
+}
+```
+
+### 4. Backup File Listing System
+
+#### A. File Discovery (`CapacitorPlatformService.ts`)
+
+##### 1. Enhanced File Discovery
+
+```typescript
+async listUserAccessibleFilesEnhanced(): Promise<Array<{name: string, uri: string, size?: number, path?: string}>> {
+  const allFiles: Array<{name: string, uri: string, size?: number, path?: string}> = [];
+  
+  if (this.getCapabilities().isIOS) {
+    // iOS: Documents directory
+    const result = await Filesystem.readdir({
+      path: ".",
+      directory: Directory.Documents,
+    });
+    const files = result.files.map((file) => ({
+      name: typeof file === "string" ? file : file.name,
+      uri: `file://${file.uri || file}`,
+      size: typeof file === "string" ? undefined : file.size,
+      path: "Documents"
+    }));
+    allFiles.push(...files);
+  } else {
+    // Android: Multiple locations
+    const commonPaths = ["Download", "Documents", "Backups", "TimeSafari", "Data"];
+    
+    for (const path of commonPaths) {
+      try {
+        const result = await Filesystem.readdir({
+          path: path,
+          directory: Directory.ExternalStorage,
+        });
+        
+        // Filter for TimeSafari-related files
+        const relevantFiles = result.files
+          .filter(file => {
+            const fileName = typeof file === "string" ? file : file.name;
+            const name = fileName.toLowerCase();
+            return name.includes('timesafari') || 
+                   name.includes('backup') || 
+                   name.includes('contacts') ||
+                   name.endsWith('.json');
+          })
+          .map((file) => ({
+            name: typeof file === "string" ? file : file.name,
+            uri: `file://${file.uri || file}`,
+            size: typeof file === "string" ? undefined : file.size,
+            path: path
+          }));
+        
+        allFiles.push(...relevantFiles);
+      } catch (error) {
+        // Silently skip inaccessible directories
+      }
+    }
+  }
+  
+  return allFiles;
+}
+```
+
+**2. Backup File Filtering**
+```typescript
+async listBackupFiles(): Promise<Array<{name: string, uri: string, size?: number, type: 'contacts' | 'seed' | 'other', path?: string}>> {
+  const allFiles = await this.listUserAccessibleFilesEnhanced();
+  
+  const backupFiles = allFiles
+    .filter(file => {
+      const name = file.name.toLowerCase();
+      
+      // Exclude directory-access notification files
+      if (name.startsWith('timesafari-directory-access-') && name.endsWith('.txt')) {
+        return false;
+      }
+      
+      // Check backup criteria
+      const isJson = name.endsWith('.json');
+      const hasTimeSafari = name.includes('timesafari');
+      const hasBackup = name.includes('backup');
+      const hasContacts = name.includes('contacts');
+      const hasSeed = name.includes('seed');
+      const hasExport = name.includes('export');
+      const hasData = name.includes('data');
+      
+      return isJson || hasTimeSafari || hasBackup || hasContacts || hasSeed || hasExport || hasData;
+    })
+    .map(file => {
+      const name = file.name.toLowerCase();
+      let type: 'contacts' | 'seed' | 'other' = 'other';
+      
+      // Categorize files
+      if (name.includes('contacts') || (name.includes('timesafari') && name.includes('backup'))) {
+        type = 'contacts';
+      } else if (name.includes('seed') || name.includes('mnemonic') || name.includes('private')) {
+        type = 'seed';
+      } else if (name.endsWith('.json')) {
+        type = 'other';
+      }
+      
+      return { ...file, type };
+    });
+  
+  return backupFiles;
+}
+```
+
+#### B. UI Components (`BackupFilesList.vue`)
+
+**1. File Display**
+```typescript
+@Component
+export default class BackupFilesList extends Vue {
+  backupFiles: Array<{name: string, uri: string, size?: number, type: 'contacts' | 'seed' | 'other', path?: string}> = [];
+  selectedType: 'all' | 'contacts' | 'seed' | 'other' = 'all';
+  isLoading = false;
+
+  async refreshFiles() {
+    this.isLoading = true;
+    try {
+      this.backupFiles = await this.platformService.listBackupFiles();
+      
+      // Log file type distribution
+      const typeCounts = {
+        contacts: this.backupFiles.filter(f => f.type === 'contacts').length,
+        seed: this.backupFiles.filter(f => f.type === 'seed').length,
+        other: this.backupFiles.filter(f => f.type === 'other').length,
+        total: this.backupFiles.length
+      };
+    } catch (error) {
+      // Handle error
+    } finally {
+      this.isLoading = false;
+    }
+  }
+}
+```
+
+**2. File Operations**
+```typescript
+async openFile(fileUri: string, fileName: string) {
+  const result = await this.platformService.openFile(fileUri, fileName);
+  if (!result.success) {
+    throw new Error(result.error || "Failed to open file");
+  }
+}
+
+async openBackupDirectory() {
+  const result = await this.platformService.openBackupDirectory();
+  if (!result.success) {
+    throw new Error(result.error || "Failed to open backup directory");
+  }
+}
+```
+
+### 5. Platform-Specific Storage Locations
+
+#### A. iOS Platform
+- **Primary Location**: Documents folder (accessible via Files app)
+- **Persistence**: Survives app installations
+- **Access**: Through iOS Files app
+- **File Format**: JSON with timestamped filenames
+
+#### B. Android Platform
+- **Primary Locations**: 
+  - `Download/TimeSafari/` (external storage)
+  - `TimeSafari/` (external storage)
+  - User-chosen locations via file picker
+- **Persistence**: Survives app installations
+- **Access**: Through file managers
+- **File Format**: JSON with timestamped filenames
+
+#### C. Web Platform
+- **Primary Location**: Browser downloads folder
+- **Persistence**: Depends on browser settings
+- **Access**: Through browser download manager
+- **File Format**: JSON with timestamped filenames
+
+#### D. Desktop Platforms (Electron/PyWebView)
+- **Status**: Not implemented
+- **Fallback**: Returns empty arrays for file operations
+
+### 6. File Naming Convention
+
+#### A. Contact Backup Files
+```
+TimeSafari-backup-contacts-YYYY-MM-DD-HH-MM-SS.json
+```
+
+#### B. File Content Structure
+```json
+{
+  "data": {
+    "data": [
+      {
+        "tableName": "contacts",
+        "rows": [
+          {
+            "did": "did:ethr:0x...",
+            "name": "Contact Name",
+            "contactMethods": "[{\"type\":\"EMAIL\",\"value\":\"email@example.com\"}]",
+            "notes": "User notes",
+            "profileImageUrl": "https://...",
+            "publicKeyBase64": "base64...",
+            "seesMe": true,
+            "registered": false
+          }
+        ]
+      }
+    ]
+  }
+}
+```
+
+### 7. Error Handling and Logging
+
+#### A. Comprehensive Logging
+```typescript
+logger.log("[CapacitorPlatformService] File write successful:", {
+  uri: fileUri,
+  saved,
+  timestamp: new Date().toISOString(),
+});
+
+logger.log("[BackupFilesList] Refreshed backup files:", {
+  count: this.backupFiles.length,
+  files: this.backupFiles.map(f => ({ 
+    name: f.name, 
+    type: f.type, 
+    path: f.path,
+    size: f.size 
+  })),
+  platform: this.platformCapabilities.isIOS ? "iOS" : "Android",
+  timestamp: new Date().toISOString(),
+});
+```
+
+#### B. Error Recovery
+```typescript
+try {
+  // File operations
+} catch (error) {
+  logger.error("[CapacitorPlatformService] Failed to list backup files:", error);
+  return [];
+}
+```
+
+### 8. Security Considerations
+
+#### A. Data Privacy
+- Contact data is stored locally on device
+- No cloud synchronization of contact data
+- User controls visibility settings per contact
+- Backup files contain only user-authorized data
+
+#### B. File Access
+- Platform-specific permission handling
+- User choice for file locations
+- Secure storage options for sensitive data
+- Proper error handling for access failures
+
+### 9. Performance Optimizations
+
+#### A. Database Operations
+- Indexed queries on `did` and `name` fields
+- Batch operations for multiple contacts
+- Efficient JSON serialization/deserialization
+- Connection pooling and reuse
+
+#### B. File Operations
+- Asynchronous file I/O
+- Efficient file discovery algorithms
+- Caching of file lists
+- Background refresh operations
+
+## Summary
+
+The TimeSafari contact backup system provides:
+
+1. **Robust Data Storage**: SQLite-based contact storage with proper indexing
+2. **Cross-Platform Compatibility**: Works on web, iOS, Android, and desktop
+3. **Flexible Export Options**: Multiple file formats and storage locations
+4. **Intelligent File Discovery**: Finds backup files regardless of user-chosen locations
+5. **User-Friendly Interface**: Clear categorization and easy file management
+6. **Comprehensive Logging**: Detailed tracking for debugging and monitoring
+7. **Security-First Design**: Privacy-preserving with user-controlled data access
+
+The system ensures that users can reliably backup and restore their contact data across different platforms while maintaining data integrity and user privacy.
