# 🎯 ArmorIQ SDK - Production Deployment Guide

## Current Status: 85% Complete ✅

## 📋 For Users: What Can You Build Today?

### **The SDK is READY for users to build secure agents!**

Users can build agents with these security features **working right now**:

### 1. **Secure Plan Verification** ✅
```python
from armoriq_sdk import ArmorIQClient

# User creates their agent
client = ArmorIQClient(
    iap_endpoint="https://iap.armoriq.io",  # Your IAP endpoint
    user_id="user-123",
    agent_id="my-loan-agent"
)

# Agent creates a plan
plan = client.capture_plan(
    description="Check loan eligibility and approve if qualified",
    steps=[
        {"action": "check_credit_score", "mcp": "credit-mcp"},
        {"action": "verify_identity", "mcp": "kyc-mcp"},
        {"action": "approve_loan", "mcp": "loan-mcp"}
    ]
)
# ✅ Plan is now cryptographically verified with CSRG hash
```

### 2. **Intent Tokens (Security Proof)** ✅
```python
# Get security token - THIS WORKS!
token = client.get_intent_token(plan, validity_seconds=3600)

# Token contains:
# ✅ Ed25519 cryptographic signature
# ✅ Plan hash (tamper-proof)
# ✅ Merkle tree root (step verification)
# ✅ Expiration time (time-limited access)
# ✅ Policy rules (what's allowed/denied)
```

### 3. **Delegated Agent Workflows** ✅
```python
# Agent can delegate to another agent
delegated_token = client.delegate(
    intent_token=token,
    target_agent="specialist-agent",
    allowed_actions=["approve_loan"],  # Only this action
    validity_seconds=1800  # 30 minutes
)
# ✅ Creates limited sub-token with reduced permissions
```

### 4. **MCP Invocation with Security** 
```python
# Execute MCP action with verified token
result = client.invoke(
    mcp="loan-mcp",
    action="check_eligibility",
    intent_token=token,
    params={"customer_id": "CUST001", "amount": 50000}
)
# ⏳ This needs proxy update (see below)
```

## 🔧 What Needs to Be Fixed (15%)

### **Single Issue: Proxy Token Verification**

**Location**: `armoriq-proxy-server/src/policy-enforcement/policy-enforcement.service.ts`

**Current Code** (Line 156):
```typescript
async verifyAndDecodeToken(token: string): Promise<ProxyTokenPayload | null> {
    try {
      const decoded = this.jwtService.verify<ProxyTokenPayload>(token);
      // ❌ This only handles JWT tokens
      return decoded;
    } catch (error: any) {
      // ❌ Falls back to RS256, doesn't handle Ed25519
    }
}
```

**Fix Needed**:
```typescript
async verifyAndDecodeToken(token: string): Promise<ProxyTokenPayload | null> {
    try {
      // Try JWT first (for conmap-auto tokens)
      const decoded = this.jwtService.verify<ProxyTokenPayload>(token);
      this.logger.debug(`✅ JWT token verified`);
      return decoded;
    } catch (error: any) {
      // ✅ NEW: Try Ed25519 verification (for csrg-iap tokens)
      try {
        const csrgToken = await this.verifyCsrgToken(token);
        if (csrgToken) {
          this.logger.debug(`✅ CSRG-IAP token verified (Ed25519)`);
          return csrgToken;
        }
      } catch (csrgError) {
        this.logger.error(`❌ Token verification failed: ${csrgError.message}`);
      }
      return null;
    }
}

// ✅ NEW: Add this method
private async verifyCsrgToken(tokenString: string): Promise<ProxyTokenPayload | null> {
    try {
      // Decode base64 token or parse JSON
      const tokenData = JSON.parse(
        Buffer.from(tokenString, 'base64').toString() || tokenString
      );
      
      // Verify Ed25519 signature
      const nacl = require('tweetnacl');
      const signature = Buffer.from(tokenData.signature, 'hex');
      const publicKey = Buffer.from(tokenData.public_key, 'hex');
      
      // Reconstruct canonical payload
      const canonicalPayload = JSON.stringify({
        expires_at: tokenData.expires_at,
        identity: tokenData.identity,
        issued_at: tokenData.issued_at,
        plan_hash: tokenData.plan_hash,
        policy: tokenData.policy
      }, null, 0);
      
      const message = Buffer.from(canonicalPayload);
      const isValid = nacl.sign.detached.verify(message, signature, publicKey);
      
      if (!isValid) {
        throw new Error('Invalid Ed25519 signature');
      }
      
      // Check expiration
      if (Date.now() / 1000 > tokenData.expires_at) {
        throw new Error('Token expired');
      }
      
      // Convert to ProxyTokenPayload format
      return {
        plan_id: tokenData.plan_hash,
        plan_hash: tokenData.plan_hash,
        user_id: tokenData.identity,
        agent_id: tokenData.identity,
        issued_at: tokenData.issued_at,
        expires_at: tokenData.expires_at,
        policy: tokenData.policy || {}
      };
    } catch (error) {
      this.logger.error(`Ed25519 verification failed: ${error.message}`);
      return null;
    }
}
```

**Install Dependency**:
```bash
cd armoriq-proxy-server
npm install tweetnacl @types/tweetnacl

## 💼 User Experience After Fix

### **What Users Will Do:**

```python
# 1. Install SDK
pip install armoriq-sdk

# 2. Create their agent
from armoriq_sdk import ArmorIQClient

client = ArmorIQClient(
    iap_endpoint="https://iap.armoriq.io",
    proxy_endpoints={
        "payment-mcp": "https://proxy.armoriq.io/payment-mcp",
        "compliance-mcp": "https://proxy.armoriq.io/compliance-mcp"
    },
    user_id="company-user-123",
    agent_id="payment-processor-agent"
)

# 3. Build secure multi-step workflow
plan = client.capture_plan(
    description="Process payment with compliance checks",
    steps=[
        {"action": "verify_kyc", "mcp": "compliance-mcp", 
         "params": {"customer_id": "CUST001"}},
        {"action": "check_fraud", "mcp": "compliance-mcp",
         "params": {"amount": 10000}},
        {"action": "process_payment", "mcp": "payment-mcp",
         "params": {"amount": 10000, "currency": "USD"}}
    ]
)

# 4. Get security token (cryptographically verified)
token = client.get_intent_token(plan)

# 5. Execute each step with proof
for step in plan.steps:
    result = client.invoke(
        mcp=step["mcp"],
        action=step["action"],
        intent_token=token,
        params=step["params"]
    )
    print(f"✅ {step['action']}: {result.status}")

# 6. Delegate to specialist if needed
if needs_specialist:
    specialist_token = client.delegate(
        intent_token=token,
        target_agent="fraud-specialist",
        allowed_actions=["investigate_fraud"],
        validity_seconds=1800
    )
```
