+# 🎖️ Veilith - Military Features Implementation
+
+## ✅ **IMPLEMENTED - Critical War Zone Features**
+
+### 🔥 **Priority 1: CRITICAL (Implemented)**
+
+#### 1. ✅ **Embedded Tor Bundle**
+**File:** `transport/tor/embedded.go`
+
+**What it does:**
+- Bundles Tor binary directly in the executable
+- No external Tor daemon required
+- Auto-starts Tor on launch
+- Auto-configures hidden service
+- Supports bridge mode (anti-censorship)
+
+**Usage:**
+```go
+// Create embedded Tor instance
+config := &tor.EmbeddedTorConfig{
+    DataDir:    "./tor-data",
+    UseBridges: true,
+    Bridges:    tor.GetDefaultBridges(),
+    AutoStart:  true,
+}
+
+embeddedTor, _ := tor.NewEmbeddedTor(config)
+
+// Get SOCKS proxy address
+proxyAddr := embeddedTor.GetSOCKSProxy()
+// 127.0.0.1:9050
+
+// Get our .onion address
+onionAddr := embeddedTor.GetOnionAddress()
+// abc123...xyz.onion
+```
+
+**Military Benefits:**
+- ✅ Works without Internet infrastructure
+- ✅ No system installation required
+- ✅ Bypasses censorship with bridges
+- ✅ Auto-configures in hostile networks
+
+---
+
+#### 2. ✅ **Mesh Peer Auto-Discovery**
+**File:** `transport/mesh/discovery.go`
+
+**What it does:**
+- Automatically discovers nearby peers (no manual IP config)
+- UDP broadcast discovery on LAN
+- Supports future mDNS/Bonjour
+- Real-time peer presence detection
+
+**Usage:**
+```go
+// Create local peer info
+localPeer := &mesh.PeerInfo{
+    Address:   "192.168.1.100:8083",
+    PublicKey: identity.GetPublicKeyHex(),
+    Nickname:  "Soldier-Alpha",
+    IsRelay:   true,
+}
+
+// Start discovery
+discovery, _ := mesh.NewPeerDiscovery(localPeer, nil)
+discovery.Start(nil)
+
+// Set callback for new peers
+discovery.SetOnPeerFound(func(peer *mesh.PeerInfo) {
+    fmt.Printf("✓ Found peer: %s at %s\n", peer.Nickname, peer.Address)
+})
+
+// Get all discovered peers
+peers := discovery.GetPeers()
+```
+
+**Military Benefits:**
+- ✅ Zero-configuration networking
+- ✅ Works in isolated networks (no Internet)
+- ✅ Automatic soldier-to-soldier connections
+- ✅ Real-time battlefield mesh
+
+**Scenario:**
+```
+Soldier A (building)
+    ↓ Auto-discovers via UDP broadcast
+Soldier B (street, 50m away)
+    ↓ Auto-discovered
+Soldier C (checkpoint, 100m away)
+
+All connect automatically - no IP configuration!
+```
+
+---
+
+#### 3. ✅ **Store-and-Forward Message Queue**
+**File:** `transport/mesh/storeforward.go`
+
+**What it does:**
+- Stores messages if recipient is offline
+- Auto-delivers when recipient comes online
+- Multi-hop routing support
+- Persistent queue on disk
+
+**Usage:**
+```go
+// Create message queue
+queue, _ := mesh.NewMessageQueue(&mesh.QueueConfig{
+    QueueDir:    "./message-queue",
+    MaxAge:      24 * time.Hour,
+    MaxAttempts: 10,
+    MaxHops:     5,
+})
+
+// Enqueue message for offline recipient
+msg := &mesh.QueuedMessage{
+    ID:          "msg-001",
+    From:        senderPubKey,
+    To:          recipientPubKey,
+    Content:     encryptedContent,
+    Timestamp:   time.Now(),
+    MaxAttempts: 10,
+    MaxHops:     5,
+    Priority:    1,
+}
+
+queue.Enqueue(msg)
+
+// Later, when recipient comes online
+messages := queue.Dequeue(recipientPubKey)
+```
+
+**Military Benefits:**
+- ✅ Messages survive network outages
+- ✅ Multi-hop delivery through intermediate soldiers
+- ✅ Critical for intermittent connectivity
+- ✅ Persistent queue survives restarts
+
+**Scenario:**
+```
+T=0:  Soldier A sends message to HQ (offline)
+      → Message stored in queue
+
+T=10: Soldier B (checkpoint) comes in range
+      → Message forwarded to Soldier B
+
+T=20: Soldier B gets Internet connection
+      → Message forwarded to HQ via Tor
+
+T=30: HQ receives message
+      → Message delivered successfully
+```
+
+---
+
+#### 4. ✅ **Emergency Wipe System**
+**File:** `security/wipe.go`
+
+**What it does:**
+- Secure data destruction (DOD 5220.22-M standard)
+- 7-pass overwrite (zeros, ones, random)
+- Panic button for instant wipe
+- Dead man's switch (auto-wipe if no activity)
+
+**Usage:**
+```go
+// Create emergency wipe system
+wipe := security.NewEmergencyWipe(&security.WipeConfig{
+    DataDir:      "./data",
+    IdentityPath: "./data/identity.enc",
+    ContactsPath: "./data/contacts.enc",
+    QueueDir:     "./message-queue",
+    TempDir:      "./temp",
+    Passes:       7, // DOD standard
+})
+
+// PANIC BUTTON - instant wipe
+wipe.Wipe()
+
+// OR: Quick single-pass wipe (faster)
+wipe.QuickWipe()
+
+// OR: Dead man's switch (auto-wipe after 24h no activity)
+dms := security.NewDeadMansSwitch(24*time.Hour, func() {
+    wipe.Wipe()
+    os.Exit(0)
+})
+dms.Start()
+
+// Reset timer on user activity
+dms.Reset()
+```
+
+**Military Benefits:**
+- ✅ Instant data destruction if captured
+- ✅ 7-pass wipe prevents forensic recovery
+- ✅ Auto-wipe if soldier killed/captured
+- ✅ Protects classified information
+
+**Scenario - Soldier Captured:**
+```
+Soldier detects enemy approaching
+    ↓
+Press panic button (Ctrl+Alt+Del+F12)
+    ↓
+Emergency wipe initiated
+    ↓
+7-pass overwrite of all data
+    ↓
+Identity destroyed - cannot be recovered
+    ↓
+Contacts destroyed - network protected
+    ↓
+Message queue destroyed - no intel leak
+```
+
+---
+
+#### 5. ✅ **Multi-Transport Failover**
+**File:** `transport/failover.go`
+
+**What it does:**
+- Automatic failover between transports
+- Priority: Tor → Mesh → Bluetooth → Direct
+- Health checking and auto-recovery
+- Exponential backoff retry
+
+**Usage:**
+```go
+// Create transports in priority order
+transports := []transport.Transport{
+    torTransport,       // 1st choice: Tor (if Internet available)
+    meshTransport,      // 2nd choice: Mesh (P2P)
+    bluetoothTransport, // 3rd choice: Bluetooth (short range)
+    directTransport,    // 4th choice: Direct TCP (last resort)
+}
+
+// Create failover transport
+failover := transport.NewFailoverTransport(transports, &transport.FailoverConfig{
+    RetryInterval: 5 * time.Second,
+    MaxRetries:    3,
+})
+
+// Set callback for failover events
+failover.SetOnFailover(func(from, to transport.TransportType) {
+    fmt.Printf("⚠️  Failing over: %s → %s\n", from, to)
+})
+
+// Connect - automatically tries transports in order
+conn, _ := failover.Connect(address)
+
+// OR: Connect with retry and exponential backoff
+conn, _ := failover.ConnectWithRetry(address, 10)
+```
+
+**Military Benefits:**
+- ✅ Seamless transition between networks
+- ✅ Always uses best available transport
+- ✅ Automatic recovery from failures
+- ✅ Maximizes connectivity in war zones
+
+**Scenario - Network Transitions:**
+```
+T=0:  In base with Internet → Uses Tor
+      ✓ Best security, good bandwidth
+
+T=10: Internet cut by enemy → Fails over to Mesh
+      ✓ P2P with nearby soldiers
+
+T=20: Soldiers out of range → Fails over to Bluetooth
+      ✓ Short-range direct comms
+
+T=30: New soldier in range → Mesh reconnects
+      ✓ Auto-recovery to better transport
+```

+
+## 🎯 **War Zone Scenarios**
+
+### **Scenario 1: Urban Combat (No Internet)**
+
+**Situation:**
+- Internet infrastructure destroyed
+- 5 soldiers scattered in buildings
+- Need to coordinate attack
+
+**Solution:**
+```go
+// Each soldier's device auto-discovers others
+discovery.Start(nil)
+
+// Auto-connect via mesh (no Internet needed)
+failover := NewFailoverTransport([]Transport{meshTransport})
+
+// Send tactical message
+msg := "Enemy position: coordinates 123,456"
+queue.Enqueue(msg)
+
+// Message auto-forwards through soldier-to-soldier mesh
+// Even if some soldiers offline, message eventually reaches all
+```
+
+**Result:** ✅ Communication maintained without Internet
+
+---
+
+### **Scenario 2: Behind Enemy Lines (Censorship)**
+
+**Situation:**
+- Tor blocked by deep packet inspection
+- Need to contact HQ secretly
+
+**Solution:**
+```go
+// Use Tor bridges to bypass censorship
+embeddedTor.SetBridges(tor.GetDefaultBridges())
+
+// Obfs4 makes Tor traffic look like normal HTTPS
+// Enemy cannot detect or block
+```
+
+**Result:** ✅ Censorship bypassed, HQ contacted
+
+---
+
+### **Scenario 3: Soldier Captured**
+
+**Situation:**
+- Soldier captured by enemy
+- USB drive with Veilith seized
+- Enemy attempting to extract contacts/intel
+
+**Solution:**
+```go
+// Before capture: Panic button pressed
+wipe.Wipe()
+
+// 7-pass DOD wipe initiated:
+// Pass 1: All zeros
+// Pass 2: All ones
+// Pass 3: Random data
+// ... (7 total passes)
+
+// Result: All data forensically unrecoverable
+```
+
+**Result:** ✅ Network protected, no intel leaked
+
+---
+
+### **Scenario 4: Intermittent Satellite Link**
+
+**Situation:**
+- Remote outpost with satellite Internet
+- Connection drops every 10 minutes
+- Critical intel must reach HQ
+
+**Solution:**
+```go
+// Store-and-forward handles disconnections
+queue.Enqueue(criticalMessage)
+
+// Failover auto-switches:
+// Satellite up   → Send via Tor
+// Satellite down → Store in queue
+// Satellite up   → Auto-retry send
+
+// Message eventually delivered despite outages
+```
+
+**Result:** ✅ Message delivered despite intermittent connectivity
+
