-# AI Instructions
-
-You have access to the **network** MCP (Model Context Protocol) server for this project. This MCP provides deep, pre-analyzed context about the codebase that is far more accurate than default file searching.
-
-## IMPORTANT: Always Use MCP First
-
-**Before making any code changes or answering questions about this codebase, ALWAYS consult the MCP tools first.**
-
-The MCP has pre-indexed the entire codebase with semantic understanding, embeddings, and structural analysis. While you can use your own file search capabilities, the MCP provides much better context because:
-- It understands code semantics, not just text matching
-- It has pre-analyzed the architecture, patterns, and relationships
-- It can answer questions about intent and purpose, not just content
-
-## Available MCP Tools
-
-### Code Understanding
-- `network_ask_question` - Ask natural language questions about the codebase. Use this for "how does X work?", "where is Y implemented?", "what does Z do?" questions. The MCP will search relevant code and provide informed answers.
-- `network_search_code` - Semantic code search. Find code by meaning, not just text. Great for finding implementations, patterns, or related functionality.
-- `network_get_architecture` - Get the full project architecture overview including tech stack, design patterns, domain entities, and API endpoints.
-- `network_get_file_summary` - Get a detailed summary of what a specific file does, its purpose, exports, and responsibilities.
-- `network_find_function` - Find a specific function or method definition by name across the codebase.
-- `network_list_functions` - List all functions defined in a specific file.
-
-### Skills (Learned Procedures)
-Skills are reusable procedures that the agent has learned about this specific project (e.g., "how to deploy", "how to run tests", "how to add a new API endpoint").
-
-- `network_list_skills` - List all learned skills for this project.
-- `network_get_skill` - Get detailed information about a specific skill including its step-by-step procedure.
-- `network_execute_skill` - Get the procedure for a learned skill so you can execute it step by step. Returns prerequisites, warnings, and commands to run.
-- `network_learn_skill` - Teach the agent a new skill. The agent will explore, discover, and memorize how to perform this task.
-- `network_get_learning_status` - Check the status of an ongoing skill learning session.
-- `network_answer_question` - Answer a question that the learning agent asked during skill learning.
-- `network_cancel_learning` - Cancel an active learning session.
-- `network_forget_skill` - Delete a learned skill.
-- `network_update_skill` - Update a learned skill with corrections or new information (e.g., 'Use .env.prod instead of .env', 'Add step to backup database first', 'The port should be 3000 not 8080').
-
-#### Skill Learning Workflow (IMPORTANT)
-
-When learning a skill, follow this **collaborative, goal-oriented workflow**. You (Cursor) are the executor, the MCP agent provides guidance:
-
-**Goal-Oriented Learning**: The agent identifies specific GOALS (pieces of information to gather) and tracks progress by goal completion, not by iterations.
-
-1. **Start Learning**: Call `learn_skill` with name and detailed description
-2. **Monitor Progress**: Call `get_learning_status` to check progress
-3. **Handle Status Responses**:
-   - `active` → Learning in progress, check again in a few seconds
-   - `waiting_input` → The agent has a question. Read it and call `answer_question` with your response
-   - `waiting_execution` → **IMPORTANT**: The agent needs you to run a command!
-     - Read the `pendingExecution.command` from the response
-     - **Execute the command yourself** using your terminal access
-     - Call `answer_question` with the command output
-   - `completed` → Skill learned successfully!
-   - `failed` → Check errors and try again
-4. **Repeat** steps 2-3 until status is `completed`
-
-**Key Insight**: The MCP agent runs on the server and cannot SSH to remote servers directly. When it needs remote access, it generates the SSH command for YOU to execute. You have terminal access - use it!
-
-**User Override Commands**: If the agent gets stuck, you can include these keywords in your answer:
-- `COMPLETE` or `SKIP` - Skip to synthesis phase and generate the skill from current data
-- `PHASE:synthesizing` - Force transition to drafting phase
-- `GOAL:goal_id=value` - Directly provide a goal's value (e.g., `GOAL:cluster_secret=abc123`)
-- `I have provided X` - Tell the agent it already has certain information
-
-**Example for `waiting_execution`**:
-```
-// Status response shows:
-// pendingExecution: { command: "ssh root@192.168.1.1 'ls -la /home/user/.orama'" }
-// 
-// You should:
-// 1. Run the command in your terminal
-// 2. Get the output
-// 3. Call answer_question with the output
-```
-
-## Recommended Workflow
-
-1. **For questions:** Use `network_ask_question` or `network_search_code` to understand the codebase.

+- `handlers/serverless/` - Serverless function deployment and execution
+
+### 2. Client SDK (`pkg/client/`)
+
+Provides a clean Go SDK for interacting with the Orama Network.
+
+**Architecture:**
+```go
+// Main client interface
+type NetworkClient interface {
+    Storage() StorageClient
+    Cache() CacheClient
+    Database() DatabaseClient
+    PubSub() PubSubClient
+    Serverless() ServerlessClient

+```go
+import "github.com/DeBrosOfficial/network/pkg/client"
+
+// Create client
+cfg := client.DefaultClientConfig()
+cfg.GatewayURL = "https://api.orama.network"
+cfg.APIKey = "your-api-key"
+
+c := client.NewNetworkClient(cfg)
+
+// Use storage
+resp, err := c.Storage().Upload(ctx, data, "file.txt")
+
+// Use cache
+err = c.Cache().Set(ctx, "key", value, 0)
+
+// Query database
+rows, err := c.Database().Query(ctx, "SELECT * FROM users")
+
+// Publish message
+err = c.PubSub().Publish(ctx, "chat", []byte("hello"))
+
+// Deploy function
+fn, err := c.Serverless().Deploy(ctx, def, wasmBytes)
+
+// Invoke function
+result, err := c.Serverless().Invoke(ctx, "function-name", input)
+```
+
+### 3. Database Layer (`pkg/rqlite/`)
+
+ORM-like interface over RQLite distributed SQL database.
+
+**Key Files:**
+- `client.go` - Main ORM client

+    Where("age > ?", 18).
+    OrderBy("name ASC").
+    Limit(10).
+    GetMany(ctx, &users)
+
+// Repository pattern
+type User struct {
+    ID    int    `db:"id"`
+    Name  string `db:"name"`
+    Email string `db:"email"`
+}
+
+repo := client.Repository("users")
+user := &User{Name: "Alice", Email: "alice@example.com"}
+err := repo.Save(ctx, user)
+```
+
+### 4. Serverless Engine (`pkg/serverless/`)
+
+WebAssembly (WASM) function execution engine with host functions.
+
+**Architecture:**
+```

+```
+
+### 6. Shared Utilities
+
+**HTTP Utilities (`pkg/httputil/`):**
+- Request parsing and validation
+- JSON response writers
+- Error handling
+- Authentication extraction
+
+**Error Handling (`pkg/errors/`):**
+- Typed errors (ValidationError, NotFoundError, etc.)
+- HTTP status code mapping
+- Error wrapping with context
+- Stack traces
+
+**Contracts (`pkg/contracts/`):**
+- Interface definitions for all services
+- Enables dependency injection

+
+## Data Flow
+
+### 1. HTTP Request Flow
+
+```
+Client Request
+    ↓
+[HTTPS Termination]
+    ↓
+[Authentication Middleware]
+    ↓
+[Route Handler]
+    ↓
+[Service Layer]
+    ↓
+[Backend Service] (RQLite/Olric/IPFS)
+    ↓
+[Response Formatting]
+    ↓
+Client Response
+```
+
+### 2. WebSocket Flow (Pub/Sub)
+
+```
+Client WebSocket Connect
+    ↓
+[Upgrade to WebSocket]
+    ↓
+[Authentication]
+    ↓
+[Subscribe to Topic]
+    ↓
+[LibP2P PubSub] ←→ [Local Subscribers]
+    ↓
+[Message Broadcasting]
+    ↓
+Client Receives Messages
+```
+
+### 3. Serverless Invocation Flow
+
+```
+Function Deployment:
+    Upload WASM → Store in IPFS → Save Metadata (RQLite) → Compile Module
+
+Function Invocation:
+    Request → Load Metadata → Get WASM from IPFS →
+    Execute in Sandbox → Return Result → Log Invocation
+```
+
+## Security Architecture
+
+### Authentication Methods
+
+1. **Wallet Signatures** (Ethereum-style)
+   - Challenge/response flow
+   - Nonce-based to prevent replay attacks
+   - Issues JWT tokens after verification
+
+2. **API Keys**
+   - Long-lived credentials
+   - Stored in RQLite
+   - Namespace-scoped
+
+3. **JWT Tokens**
+   - Short-lived (15 min default)
+   - Refresh token support
+   - Claims-based authorization
+
+### TLS/HTTPS
+
+- Automatic ACME (Let's Encrypt) certificate management
+- TLS 1.3 support
+- HTTP/2 enabled
+- Certificate caching
+
+### Middleware Stack
+
+1. **Logger** - Request/response logging
+2. **CORS** - Cross-origin resource sharing
+3. **Authentication** - JWT/API key validation
+4. **Authorization** - Namespace access control
+5. **Rate Limiting** - Per-client rate limits
+6. **Error Handling** - Consistent error responses
+
+## Scalability
+
+### Horizontal Scaling
+
+- **Gateway:** Stateless, can run multiple instances behind load balancer
+- **RQLite:** Multi-node cluster with Raft consensus
+- **IPFS:** Distributed storage across nodes
+- **Olric:** Distributed cache with consistent hashing
+
+### Caching Strategy
+
+1. **WASM Module Cache** - Compiled modules cached in memory
+2. **Olric Distributed Cache** - Shared cache across nodes
+3. **Local Cache** - Per-gateway request caching
+
+### High Availability
+
+- **Database:** RQLite cluster with automatic leader election
+- **Storage:** IPFS replication factor configurable
+- **Cache:** Olric replication and eventual consistency
+- **Gateway:** Stateless, multiple replicas supported
+
+## Monitoring & Observability
+
+### Health Checks
+
+- `/health` - Liveness probe
+- `/v1/status` - Detailed status with service checks
+
+### Metrics
+
+- Prometheus-compatible metrics endpoint
+- Request counts, latencies, error rates
+- Service-specific metrics (cache hit ratio, DB query times)
+
+### Logging
+
+- Structured logging (JSON format)
+- Log levels: DEBUG, INFO, WARN, ERROR
+- Correlation IDs for request tracing
+
+## Development Patterns
+
+### SOLID Principles
+
+- **Single Responsibility:** Each handler/service has one focus
+- **Open/Closed:** Interface-based design for extensibility
+- **Liskov Substitution:** All implementations conform to contracts
+- **Interface Segregation:** Small, focused interfaces
+- **Dependency Inversion:** Depend on abstractions, not implementations
+
+### Code Organization
+
+- **Average file size:** ~150 lines
+- **Package structure:** Domain-driven, feature-focused
+- **Testing:** Unit tests for logic, E2E tests for integration
+- **Documentation:** Godoc comments on all public APIs
+
+## Deployment
+
+### Development
+
+```bash
+make dev       # Start 5-node cluster
+make stop      # Stop all services
+make test      # Run unit tests
+make test-e2e  # Run E2E tests
+```
+
+### Production
+
+```bash
+# First node (creates cluster)
+sudo orama install --vps-ip <IP> --domain node1.example.com
+
+# Additional nodes (join cluster)
+sudo orama install --vps-ip <IP> --domain node2.example.com \
+    --peers /dns4/node1.example.com/tcp/4001/p2p/<PEER_ID> \
+    --join <node1-ip>:7002 \
+    --cluster-secret <secret> \
+    --swarm-key <key>
+```
+
+### Docker (Future)
+
+Planned containerization with Docker Compose and Kubernetes support.
+
+## Future Enhancements
+
+1. **GraphQL Support** - GraphQL gateway alongside REST
+2. **gRPC Support** - gRPC protocol support
+3. **Event Sourcing** - Event-driven architecture
+4. **Kubernetes Operator** - Native K8s deployment
+5. **Observability** - OpenTelemetry integration
+6. **Multi-tenancy** - Enhanced namespace isolation

+}
+```
+
+## Configuration
+
+### ClientConfig
+
+```go
+type ClientConfig struct {
+    // Gateway URL (e.g., "https://api.orama.network")
+    GatewayURL string
+
+    // Authentication (choose one)
+    APIKey    string  // API key authentication
+    JWTToken  string  // JWT token authentication
+
+    // Client options
+    Timeout   time.Duration  // Request timeout (default: 30s)
+    UserAgent string         // Custom user agent
+
+    // Network client namespace
+    Namespace string  // Default namespace for operations
+}
+```
+
+### Creating a Client
+
+```go
+// Default configuration
+cfg := client.DefaultClientConfig()
+cfg.GatewayURL = "https://api.orama.network"

+defer cancel()
+
+resp, err := c.Storage().Upload(ctx, data, "file.txt")
+```
+
+### Retry Logic
+
+```go
+import "github.com/DeBrosOfficial/network/pkg/errors"
+
+maxRetries := 3
+for i := 0; i < maxRetries; i++ {
+    resp, err := c.Storage().Upload(ctx, data, "file.txt")
+    if err == nil {
+        break
+    }
+    if !errors.ShouldRetry(err) {
+        return err
+    }
+    time.Sleep(time.Second * time.Duration(i+1))
+}
+```
+
+### Multiple Namespaces
+
+```go
+// Default namespace
+c1 := client.NewNetworkClient(cfg)
+c1.Storage().Upload(ctx, data, "file.txt") // Uses default namespace
+
+// Override namespace per request
+opts := &client.StorageUploadOptions{
+    Namespace: "custom-namespace",
+}
+c1.Storage().UploadWithOptions(ctx, data, "file.txt", opts)
+```
+
+## Testing
+
+### Mock Client
+
+```go
+// Create a mock client for testing
+mockClient := &MockNetworkClient{
+    StorageClient: &MockStorageClient{
+        UploadFunc: func(ctx context.Context, data []byte, filename string) (*UploadResponse, error) {
+            return &UploadResponse{CID: "QmMock"}, nil
+        },
+    },
+}
+
+// Use in tests
+resp, err := mockClient.Storage().Upload(ctx, data, "test.txt")
+assert.NoError(t, err)
+assert.Equal(t, "QmMock", resp.CID)
+```

+# Gateway API Documentation
+
+## Overview
+
+The Orama Network Gateway provides a unified HTTP/HTTPS API for all network services. It handles authentication, routing, and service coordination.
+
+**Base URL:** `https://api.orama.network` (production) or `http://localhost:6001` (development)
+
+## Authentication
+
+All API requests (except `/health` and `/v1/auth/*`) require authentication.
+
+### Authentication Methods
+
+1. **API Key** (Recommended for server-to-server)
+2. **JWT Token** (Recommended for user sessions)
+3. **Wallet Signature** (For blockchain integration)
+
+### Using API Keys
+
+Include your API key in the `Authorization` header:
+
+```bash
+curl -H "Authorization: Bearer your-api-key-here" \
+     https://api.orama.network/v1/status
+```
+
+Or in the `X-API-Key` header:
+
+```bash
+curl -H "X-API-Key: your-api-key-here" \
+     https://api.orama.network/v1/status
+```
+
+### Using JWT Tokens
+
+```bash
+curl -H "Authorization: Bearer your-jwt-token-here" \
+     https://api.orama.network/v1/status
+```
+

+
+---
+
+## Security Measures Implemented
+
+### 1. Firewall Configuration (UFW)
+
+**Status:** ✅ Enabled on all 4 servers
+
+#### Public Ports (Open to Internet)
+- **22/tcp** - SSH (with hardening)
+- **80/tcp** - HTTP (redirects to HTTPS)
+- **443/tcp** - HTTPS (Let's Encrypt production certificates)
+- **4001/tcp** - libp2p swarm (P2P networking)
+
+#### Cluster-Only Ports (Restricted to 4 Server IPs)
+All the following ports are ONLY accessible from the 4 cluster IPs:
+- **5001/tcp** - rqlite HTTP API
+- **7001/tcp** - SNI Gateway
+- **7002/tcp** - rqlite Raft consensus
+- **9094/tcp** - IPFS Cluster API
+- **9098/tcp** - IPFS Cluster communication
+- **3322/tcp** - Olric distributed cache
+- **4101/tcp** - IPFS swarm (cluster internal)
+
+#### Firewall Rules Example
+```bash
+sudo ufw default deny incoming
+sudo ufw default allow outgoing
+sudo ufw allow 22/tcp comment "SSH"
+sudo ufw allow 80/tcp comment "HTTP"
+sudo ufw allow 443/tcp comment "HTTPS"
+sudo ufw allow 4001/tcp comment "libp2p swarm"
+
+# Cluster-only access for sensitive services
+sudo ufw allow from 51.83.128.181 to any port 5001 proto tcp
+sudo ufw allow from 194.61.28.7 to any port 5001 proto tcp
+sudo ufw allow from 83.171.248.66 to any port 5001 proto tcp
+sudo ufw allow from 62.72.44.87 to any port 5001 proto tcp
+# (repeat for ports 7001, 7002, 9094, 9098, 3322, 4101)
+
+sudo ufw enable
+```
+
+### 2. SSH Hardening
+
+**Location:** `/etc/ssh/sshd_config.d/99-hardening.conf`
+
+**Configuration:**
+```bash
+PermitRootLogin yes               # Root login allowed with SSH keys
+PasswordAuthentication yes        # Password auth enabled (you have keys configured)
+PubkeyAuthentication yes          # SSH key authentication enabled
+PermitEmptyPasswords no           # No empty passwords
+X11Forwarding no                  # X11 disabled for security
+MaxAuthTries 3                    # Max 3 login attempts
+ClientAliveInterval 300           # Keep-alive every 5 minutes
+ClientAliveCountMax 2             # Disconnect after 2 failed keep-alives
+```
+
+**Your SSH Keys Added:**
+- ✅ `ssh-ed25519 AAAAC3NzaC1lZDI1NTE5AAAAIPcGZPX2iHXWO8tuyyDkHPS5eByPOktkw3+ugcw79yQO`
+- ✅ `ssh-rsa AAAAB3NzaC1yc2EAAAADAQABAAACAQDgCWmycaBN3aAZJcM2w4+Xi2zrTwN78W8oAiQywvMEkubqNNWHF6I3...`
+
+Both keys are installed on all 4 servers in:
+- VPS 1: `/home/ubuntu/.ssh/authorized_keys`
+- VPS 2, 3, 4: `/root/.ssh/authorized_keys`
+
+### 3. Fail2ban Protection
+
+**Status:** ✅ Installed and running on all 4 servers
+
+**Purpose:** Automatically bans IPs after failed SSH login attempts
+
+**Check Status:**
+```bash
+sudo systemctl status fail2ban
+```
+
+### 4. Security Updates
+
+**Status:** ✅ All security updates applied (as of Jan 18, 2026)
+
+**Update Command:**
+```bash
+sudo apt update && sudo apt upgrade -y
+```
+
+### 5. Let's Encrypt TLS Certificates
+
+**Status:** ✅ Production certificates (NOT staging)
+
+**Configuration:**

+```
+
+**Expected:** All 4 peer IDs listed
+
+### Olric Cache Cluster
+
+**Port:** 3320 (localhost), 3322 (cluster communication)
+
+**Test:**
+```bash
+ssh ubuntu@51.83.128.181
+ss -tulpn | grep olric
+```
+
+---
+
+## Access Credentials
+
+### SSH Access
+
+**VPS 1:**
+```bash
+ssh ubuntu@51.83.128.181
+# OR using your SSH key:
+ssh -i ~/.ssh/ssh-sotiris/id_ed25519 ubuntu@51.83.128.181
+```
+
+**VPS 2, 3, 4:**
+```bash
+ssh root@194.61.28.7
+ssh root@83.171.248.66
+ssh root@62.72.44.87
+```
+
+**Important:** Password authentication is still enabled, but your SSH keys are configured for passwordless access.
+
+---
+
+## Testing & Verification
+
+### 1. Test External Port Access (From Your Machine)
+
+```bash
+# These should be BLOCKED (timeout or connection refused):
+nc -zv 51.83.128.181 5001   # rqlite API - should be blocked
+nc -zv 51.83.128.181 7002   # rqlite Raft - should be blocked
+nc -zv 51.83.128.181 9094   # IPFS cluster - should be blocked
+
+# These should be OPEN:
+nc -zv 51.83.128.181 22     # SSH - should succeed
+nc -zv 51.83.128.181 80     # HTTP - should succeed
+nc -zv 51.83.128.181 443    # HTTPS - should succeed
+nc -zv 51.83.128.181 4001   # libp2p - should succeed
+```
+
+### 2. Test Domain Access
+
+```bash
+curl -I https://node-kv4la8.debros.network
+curl -I https://node-7prvNa.debros.network
+curl -I https://node-xn23dq.debros.network
+curl -I https://node-nns4n5.debros.network
+```
+
+All should return `HTTP/1.1 200 OK` or similar with valid SSL certificates.
+
+### 3. Test Cluster Communication (From VPS 1)
+
+```bash
+ssh ubuntu@51.83.128.181
+# Test rqlite cluster
+curl -s http://localhost:5001/status | jq -r '.store.nodes[].id'
+
+# Test IPFS cluster
+curl -s http://localhost:9094/id | jq -r '.cluster_peers[]'
+
+# Check all services running
+ps aux | grep -E "(orama-node|rqlited|ipfs|olric)" | grep -v grep
+```
+
+---
+
+## Maintenance & Operations
+
+### Firewall Management
+
+**View current rules:**
+```bash
+sudo ufw status numbered
+```
+
+**Add a new allowed IP for cluster services:**
+```bash
+sudo ufw allow from NEW_IP_ADDRESS to any port 5001 proto tcp
+sudo ufw allow from NEW_IP_ADDRESS to any port 7002 proto tcp
+# etc.
+```
+
+**Delete a rule:**
+```bash
+sudo ufw status numbered  # Get rule number
+sudo ufw delete [NUMBER]
+```
+
+### SSH Management
+
+**Test SSH config without applying:**
+```bash
+sudo sshd -t
+```
+
+**Reload SSH after config changes:**
+```bash
+sudo systemctl reload ssh
+```
+
+**View SSH login attempts:**
+```bash
+sudo journalctl -u ssh | tail -50
+```
+
+### Fail2ban Management
+
+**Check banned IPs:**
+```bash
+sudo fail2ban-client status sshd
+```
+
+**Unban an IP:**
+```bash
+sudo fail2ban-client set sshd unbanip IP_ADDRESS
+```
+
+### Security Updates
+
+**Check for updates:**
+```bash
+apt list --upgradable
+```
+
+**Apply updates:**
+```bash
+sudo apt update && sudo apt upgrade -y
+```
+
+**Reboot if kernel updated:**
+```bash
+sudo reboot
+```
+
+---
+
+## Security Improvements Completed
+
+### Before Security Audit:
+- ❌ No firewall enabled
+- ❌ rqlite database exposed to internet (port 5001, 7002)
+- ❌ IPFS cluster management exposed (port 9094, 9098)
+- ❌ Olric cache exposed (port 3322)
+- ❌ Root login enabled without restrictions (VPS 2, 3, 4)
+- ❌ No fail2ban on 3 out of 4 servers
+- ❌ 19-39 security updates pending
+
+### After Security Hardening:
+- ✅ UFW firewall enabled on all servers
+- ✅ Sensitive ports restricted to cluster IPs only
+- ✅ SSH hardened with key authentication
+- ✅ Fail2ban protecting all servers
+- ✅ All security updates applied
+- ✅ Let's Encrypt production certificates verified
+- ✅ Cluster communication tested and working
+- ✅ External access verified (HTTP/HTTPS only)
+
+---
+
+## Recommended Next Steps (Optional)
+
+These were not implemented per your request but are recommended for future consideration:
+
+1. **VPN/Private Networking** - Use WireGuard or Tailscale for encrypted cluster communication instead of firewall rules
+2. **Automated Security Updates** - Enable unattended-upgrades for automatic security patches
+3. **Monitoring & Alerting** - Set up Prometheus/Grafana for service monitoring
+4. **Regular Security Audits** - Run `lynis` or `rkhunter` monthly for security checks
+
+---
+
+## Important Notes
+
+### Let's Encrypt Configuration
+
+The Orama Network gateway uses **autocert** from Go's `golang.org/x/crypto/acme/autocert` package. The configuration is in:
+
+**File:** `/home/debros/.orama/configs/node.yaml`
+
+**Relevant settings:**
+```yaml
+http_gateway:
+  https:
+    enabled: true
+    domain: "node-kv4la8.debros.network"
+    auto_cert: true
+    cache_dir: "/home/debros/.orama/tls-cache"
+    http_port: 80
+    https_port: 443
+    email: "admin@node-kv4la8.debros.network"
+```
+
+**Important:** There is NO `letsencrypt_staging` flag set, which means it defaults to **production Let's Encrypt**. This is correct for production deployment.
+
+### Firewall Persistence
+
+UFW rules are persistent across reboots. The firewall will automatically start on boot.
+
+### SSH Key Access
+
+Both of your SSH keys are configured on all servers. You can access:
+- VPS 1: `ssh -i ~/.ssh/ssh-sotiris/id_ed25519 ubuntu@51.83.128.181`
+- VPS 2-4: `ssh -i ~/.ssh/ssh-sotiris/id_ed25519 root@IP_ADDRESS`
+
+Password authentication is still enabled as a fallback, but keys are recommended.
+
+---
+
+## Emergency Access
+
+If you get locked out:
+
+1. **VPS Provider Console:** All major VPS providers offer web-based console access
+2. **Password Access:** Password auth is still enabled on all servers
+3. **SSH Keys:** Two keys configured for redundancy
+
+**Disable firewall temporarily (emergency only):**
+```bash
+sudo ufw disable
+# Fix the issue
+sudo ufw enable
+```
+
+---
+
