+# Cloud Backup Implementation Plan (Complete)
+
+## 1. Frontend Implementation (Flutter)
+- [x] **ApiService Updates**: Added `uploadBackup` and `downloadBackup` methods to interact with the backend (endpoints `/backups/upload` and `/backups/download`).
+- [x] **LocalKeyBackupService Refactor**:
+    - [x] Updated `createEncryptedBackup` to accept `includeKeys` and `includeMessages` flags.
+    - [x] Added `uploadToCloud` method which **defaults to Messages Only** (no keys) for security.
+    - [x] Added `restoreFromCloud` method to fetch and decrypt backups.
+- [x] **UI Overhaul (LocalBackupScreen)**:
+    - [x] Added "Cloud Mode" vs "Local Mode" toggle.
+    - [x] Implemented "Zero Knowledge" warning UI when Cloud Mode is active (keys excluded by default).
+    - [x] Added visual cues for "Secure Mode".
+    - [x] Integrated `uploadToCloud` and `restoreFromCloud` calls with progress indicators and error handling.
+
+## 2. Backend Implementation (Go)
+- [x] **Database Schema**: Created migration `000003_e2ee_backup_recovery.up.sql` for:
+    - `cloud_backups` table (stores encrypted blobs).
+    - `backup_preferences` table.
+    - `user_devices` table.
+    - `sync_codes` table.
+    - `recovery_guardians` and `recovery_sessions` tables (for future social recovery).
+- [x] **API Endpoints**:
+    - `POST /backups/upload`: Accepts encrypted blob, metadata, and version.
+    - `GET /backups/download`: Retrieves latest backup.
+    - `GET /backups/download/:backup_id`: Retrieves specific backup.
+- [x] **Data Models**: Defined `CloudBackup`, `UploadBackupRequest`, `DownloadBackupResponse` structs matching frontend expectations.
+- [x] **Handler Logic**: Implemented "blind storage" logic - backend stores opaque blobs and does not attempt decryption.
+
+## 3. Deployment Status (Pending)
+- [x] **Compilation**: Successfully compiled `sojorn-api-linux` and `migrate-linux` binaries locally.
+- [ ] **Upload**: Failed to upload binaries to VPS (`194.238.28.122`) due to SSH authentication failure ("Permission denied") with provided credentials.
+- [ ] **Migration**: Database migration failed from local machine due to port 5432 being closed/filtered. Needs to be run from the VPS.
+- [ ] **Restart**: Service restart pending successful SSH access.
+
+## 4. Next Steps
+Once SSH access is restored (verify password or add public key):
+1.  **Upload Binaries**: `scp sojorn-api-linux migrate-linux root@194.238.28.122:/root/`
+2.  **Run Migration**: `ssh root@... "./migrate-linux -path ... up"`
+3.  **Restart Service**: `ssh root@... "systemctl restart sojorn-api"`

+# Feed Reactions Fix - Implementation Summary
+
+## Status: COMPLETE & DEPLOYED ✅
+
+### 1. Issue Description
+- **Problem**: Reactions were not displaying on the "Following" (Home) and "Profile" feeds. The "Postcard" UI (specifically the compact method) was defaulting to the "Add Reaction" button because no reaction data was being returned by the API for these lists.
+- **Root Cause**: The SQL queries for `GetFeed` and `GetPostsByAuthor` in the backend were not aggregating reaction data (counts and user choices), unlike the single-post endpoint.
+
+### 2. Implementation Details (Backend)
+- **File**: `internal/repository/post_repository.go`
+- **Changes**: 
+  - Modified `GetFeed` SQL query to include a correlated subquery fetching `jsonb_object_agg(emoji, count)` for `reaction_counts`.
+  - Modified `GetPostsByAuthor` SQL query to do the same.
+  - Added logic to fetch `my_reactions` (the current user's votes) for both feeds.
+  - Updated the Go `Scan` destinations to populate the `Reactions` and `MyReactions` fields in the `Post` model.
+  - **Correction**: Also fixed a missing `allow_chain` and `visibility` selection in the `GetPostsByAuthor` query, ensuring consistency across the app.
+
+### 3. Frontend logic (Verified)
+- **Widget**: `sojornPostCard` -> `PostActions` -> `ReactionsDisplay`
+- **Logic**: The `ReactionsDisplay` widget in `compact` mode (used in feeds) is designed to:
+  1. Show the user's reaction if they voted.
+  2. Else, show the "Most Used" reaction from the community.
+  3. Else (if valid data but count is 0), show the "Add" button.
+- **Result**: Now that the backend provides the data (Case 1 or 2), the UI will correctly display the reaction chips instead of just the "+" button.
+
+### 4. Deployment
+- **Server**: `194.238.28.122`
+- **Action**: 
+  - Compiled `sojorn-api-linux` locally.
+  - Uploaded to `/opt/sojorn/bin/api` via `scp` (user: `patrick`).
+  - Restarted `sojorn-api` service via `systemctl`.
+- **Status**: API is active and serving the new queries.
+
+### 5. Next Steps
+- **User Action**: Pull-to-refresh the feed in the Sojorn app to see the changes.

-## Next Steps: Message Recovery
+## Backup & Recovery System ✅
 
-### Problem
-When users uninstall the app or lose local keys, they cannot decrypt historical messages.
+### Overview
+A robust local backup and recovery system has been implemented to address the risk of data loss on device changes or app uninstalls. This system allows users to export their cryptographic identity and message history into a secure, portable file.
 
-### Solution Requirements
-1. **Key Backup Strategy**: Securely backup encryption keys
-2. **Message Recovery**: Allow decryption of historical messages after key recovery
-3. **Security**: Maintain E2EE guarantees while enabling recovery
+### Architecture
 
-### Proposed Solutions
+#### 1. Security Model
+- **Encryption**: AES-256-GCM
+- **Key Derivation**: Argon2id (from user password)
+- **Storage**: Local file system (portable JSON file)
+- **Trust**: Zero-knowledge (server never sees the backup file or password)
 
-#### Option 1: Cloud Key Backup (Recommended)
-- Encrypt identity keys with user password
-- Store encrypted backup in cloud storage
-- Recover keys with password authentication
+#### 2. Backup Content
+The encrypted backup file contains two main components:
+1.  **Key Material**:
+    *   Identity Key Pair (Ed25519 & X25519)
+    *   Signed PreKey Pair (with signature)
+    *   One-Time PreKeys (all unused keys)
+2.  **Message History** (Optional):
+    *   Full plaintext message history
+    *   Metadata (sender, timestamp, etc.)
+    *   *Note: Messages are decrypted from local storage and re-encrypted with the backup password for portability.*
 
-**Pros**:
-- Most user-friendly
-- Maintains security (password-protected)
-- Technically straightforward
-- Reversible if needed
+#### 3. Backup Flow
+1.  **User Initiation**: User selects "Full Backup & Recovery" in settings.
+2.  **Password Entry**: User sets a strong backup password.
+3.  **Data Gathering**:
+    *   `SimpleE2EEService` exports all key pairs.
+    *   (Optional) `LocalMessageStore` exports all message records.
+4.  **Encryption**:
+    *   Salt & Nonce generated.
+    *   Key derived from password via Argon2id.
+    *   Payload (keys + messages) encrypted via AES-GCM.
+5.  **File Generation**: JSON file containing ciphertext, salt, nonce, and metadata is saved to device.
 
-#### Option 2: Social Recovery
-- Allow trusted contacts to help recover keys
-- Use Shamir's Secret Sharing for security
-- Requires multiple trusted contacts
+#### 4. Restore Flow
+1.  **File Selection**: User selects the `.json` backup file.
+2.  **Decryption**:
+    *   User enters password.
+    *   Key derived using stored salt.
+    *   Payload decrypted.
+3.  **Import**:
+    *   Keys are imported into `SimpleE2EEService` and persisted to secure storage.
+    *   Messages are imported into `LocalMessageStore` and re-encrypted with the device's *new* local storage key.
 
-#### Option 3: Server-Side Recovery (Limited)
-- Store encrypted key backups on server
-- Server cannot decrypt without user password
-- Similar to Signal's approach
-
-#### Option 4: Message Re-encryption
-- Store messages encrypted with server keys
-- Re-encrypt with new keys after recovery
-- Breaks perfect forward secrecy
-
-### Implementation Plan for Key Recovery
-
-#### Phase 1: Key Backup
-1. Add password-based key encryption
-2. Implement cloud backup storage
-3. Add backup/restore UI
-4. Test backup/restore flow
-
-#### Phase 2: Message Recovery
-1. Store message headers for re-decryption
-2. Implement batch message re-decryption
-3. Add recovery progress indicators
-4. Test with historical messages
-
-#### Phase 3: Security Enhancements
-1. Add backup encryption verification
-2. Implement backup rotation
-3. Add recovery security checks
-4. Monitor recovery success rates
+### Technical Implementation
+*   **Service**: `LocalKeyBackupService` handles the encryption/decryption pipeline.
+*   **Store**: `LocalMessageStore` provides bulk export/import methods (`getAllMessageRecords`, `saveMessageRecord`).
+*   **UI**: `LocalBackupScreen` provides the interface for creating and restoring backups.

+```
+
+---
+
+## Troubleshooting
+
+### Route Not Found (404) After Deployment
+**Cause:** Old binary is still running.  
+**Solution:** Stop service before copying new binary:
+```bash
+sudo systemctl stop sojorn-api
+sudo cp sojorn-api /opt/sojorn/bin/api
+sudo systemctl start sojorn-api
+```
+
+### "Text file busy" Error
+**Cause:** Trying to overwrite running binary.  
+**Solution:** Stop the service first.
+
+### Server Not Responding
+1. Check service status: `sudo systemctl status sojorn-api`
+2. Check logs: `sudo journalctl -u sojorn-api -n 50`
+3. Verify port: `sudo netstat -tlnp | grep 8080`
+
+### Database Connection Errors
+1. Check PostgreSQL: `sudo systemctl status postgresql`
+2. Verify credentials in `/opt/sojorn/.env`
+3. Test connection: `psql -h localhost -U postgres -d sojorn`
+
+### Flutter Build Errors
+1. Clean build: `flutter clean && flutter pub get`
+2. Analyze: `flutter analyze`
+3. Check Dart version: `flutter doctor`

+# Zero Knowledge Cloud Backup - Implementation Summary
+
+## Status: COMPLETE & DEPLOYED ✅
+
+### 1. Security Architecture (Zero Knowledge)
+- **Principle**: The server never sees your private keys.
+- **Cloud Backups**: Default to **Messages Only**. The payload contains encrypted message history but explicitly excludes the key pairs needed to decrypt them.
+- **Local Backups**: Must be used to backup **Keys + Messages**. This is the only way to restore your identity (Subjective Identity).
+- **Encryption**: All data is encrypted client-side using Argon2id (password derivation) and AES-GCM (content encryption) before leaving the device.
+
+### 2. Frontend Implementation (Flutter)
+- **Service**: Rebuilt `LocalKeyBackupService.dart` to handle the dual-mode backup logic.
+- **UI**: 
+  - Added toggle for "Cloud" vs "Local" backup.
+  - "Secure Mode" indicator when uploading to cloud (confirming keys are excluded).
+  - Explicit warning: "NOT RECOMMENDED for cloud backups. Keep keys local."
+
+### 3. Backend Implementation (Go)
+- **Endpoints**: `POST /backups/upload` and `GET /backups/download` are active.
+- **Storage**: Stores opaque `encrypted_blob`, `salt`, `nonce`, and `mac`.
+- **Database**: 
+  - Applied migration `000003_e2ee_backup_recovery`.
+  - Created tables: `cloud_backups`, `backup_preferences`, `user_devices`.
+
+### 4. Deployment Details
+- **Server**: `194.238.28.122`
+- **Service**: `sojorn-api` (Restarted at ~01:55 server time)
+- **Database**: Migrations applied successfully via `migrate-linux` tool.
+
+### 5. How to Test
+1. **Create Identity Backup**: Go to "Full Backup & Recovery" -> Select "Local File" -> "Export Backup". Save this file safely!
+2. **Cloud Upload**: Switch to "Cloud Backup" -> Encrypt with password -> "Upload Backup".
+3. **Restore Flow**:
+   - Wipe app / New Device.
+   - **Step 1**: "Import Backup" using your Local File (Restores Identity/Keys).
+   - **Step 2**: "Download & Restore" from Cloud (Restores Message History).
