- **Policy Enforcement**: Flexible security policies (strict, moderate, permissive)
- **Trust Bridging**: Connect centralized and decentralized trust models

### Functions

#### `cloudadmin::authorize(admin_id: string, operation: string, resource: string) -> bool`
Check if admin is authorized for operation on resource.

**Operations:**
- `"read"` - All admin levels
- `"write"` - Admin, SuperAdmin only
- `"delete"` - SuperAdmin only

```dal
let can_write = cloudadmin::authorize("admin_001", "write", "/data/config");
let can_delete = cloudadmin::authorize("superadmin_001", "delete", "/data/users");
```

---

#### `cloudadmin::enforce_policy(policy_name: string, context: AdminContext) -> Result<bool, string>`
Enforce admin policy based on context.

**Policies:**
- `"strict"` - SuperAdmin only
- `"moderate"` - Admin or SuperAdmin
- `"permissive"` - All users

```dal
let context = cloudadmin::create_admin_context("admin_001", "admin");
let allowed = cloudadmin::enforce_policy("moderate", context);

if allowed.is_ok() && allowed.unwrap() {
    // Execute operation
}
```

---

#### `cloudadmin::validate_hybrid_trust(admin_trust: string, user_trust: string) -> bool`
Validate hybrid trust between admin and user. Both must be "valid" for success.

```dal
let admin_verified = cloudadmin::authorize(admin_id, "write", resource);
let admin_trust = if admin_verified { "valid" } else { "invalid" };

let user_verified = auth::verify_signature();
let user_trust = if user_verified { "valid" } else { "invalid" };

let is_trusted = cloudadmin::validate_hybrid_trust(admin_trust, user_trust);
```

---

#### `cloudadmin::bridge_trusts(centralized_trust: string, decentralized_trust: string) -> bool`
Bridge centralized admin trust with decentralized user trust.

**Requirements:** centralized = "admin" AND decentralized = "user"

```dal
let admin_approved = cloudadmin::authorize(admin_id, "write", "/bridge");
let centralized = if admin_approved { "admin" } else { "none" };

let user_verified = auth::verify_address(user_address);
let decentralized = if user_verified { "user" } else { "none" };

let can_bridge = cloudadmin::bridge_trusts(centralized, decentralized);
```

---

#### `cloudadmin::create_admin_context(admin_id: string, level: string) -> Option<AdminContext>`
Create admin context with specified level.

**Levels:** "superadmin", "admin", "moderator", "user"

```dal
let context = cloudadmin::create_admin_context("admin_001", "admin");

// Add permissions
context = context.with_permissions(["read_users", "write_config"]);

// Add metadata
context = context.with_metadata({
    "department": "engineering",
    "region": "us-west"
});
```

### Use Cases

- **Hybrid Marketplaces**: Admin moderation + decentralized trading
- **Regulated DeFi**: Compliance oversight + user autonomy
- **Multi-Chain Apps**: Centralized coordination + blockchain operations
- **AI Agent Systems**: Admin control + autonomous agents

### Example: Hybrid Approval System

```dal
@trust("hybrid")
@secure
service HybridApproval {
    fn approve_transaction(tx_id: string, admin_id: string, user_sig: string) -> bool {
        // Check admin authorization
        let admin_ok = cloudadmin::authorize(admin_id, "write", "/transactions");
        let admin_trust = if admin_ok { "valid" } else { "invalid" };
        
        // Verify user signature
        let user_ok = auth::verify_signature(user_sig);

## 22. admin:: - Process Management

Administrative control over system processes, agents, and resources.

### Functions

#### `admin::kill(process_id: string, reason: string) -> Result<bool, string>`
Terminate process or agent. Reason is required.

**Valid Reasons:**
- `"resource_violation"` - Excessive resource usage
- `"security_breach"` - Security threat detected
- `"policy_violation"` - Policy compliance issue
- `"maintenance"` - Scheduled maintenance

```dal
// Kill agent exceeding resources
let result = admin::kill("agent_123", "resource_violation: CPU > 90%");

if result.is_ok() {
    log::audit("admin", "Agent terminated successfully");
} else {
    log::error("admin", "Failed: " + result.error());
}
```

---

#### `admin::get_process_info(process_id: string) -> Result<ProcessInfo, string>`
Get detailed process information including resource usage.

**Returns:**
- `process_id` - Process identifier
- `name` - Process name
- `status` - Current status (running, stopped, error)
- `start_time` - Unix timestamp
- `resource_usage` - Map of resource metrics (cpu, memory, etc.)

```dal
let info = admin::get_process_info("agent_123");

if info.is_ok() {
    let process = info.unwrap();
    log::info("admin", "Process: " + process.name);
    log::info("admin", "Status: " + process.status);
    log::info("admin", "CPU: " + process.resource_usage["cpu"]);
    log::info("admin", "Memory: " + process.resource_usage["memory"]);
    
    // Check if exceeding limits
    if process.resource_usage["cpu"] > 80 {
        admin::kill(process_id, "excessive_cpu_usage");
    }
}
```

---

#### `admin::list_processes() -> Vec<ProcessInfo>`
List all running processes in the system.

```dal
let processes = admin::list_processes();

for process in processes {
    log::info("admin", "ID: " + process.process_id);
    log::info("admin", "Name: " + process.name);
    log::info("admin", "Status: " + process.status);
    
    // Monitor AI agents
    if process.name.starts_with("ai_agent_") {
        let cpu = process.resource_usage["cpu"].as_int();
        if cpu > 75 {
            log::warn("admin", "AI agent high CPU: " + process.process_id);
        }
    }
}
```

### Use Cases

- **Agent Monitoring**: Track AI agent resource usage
- **Process Lifecycle**: Manage process termination
- **Resource Control**: Enforce resource limits
- **Health Checks**: Monitor system health

### Example: Agent Health Monitor

```dal
@ai
service AgentHealthMonitor {
    fn monitor_agents() {
        let processes = admin::list_processes();
        
        for process in processes {
            // Check if it's an AI agent
            if process.name.starts_with("ai_agent_") {
                let cpu = process.resource_usage["cpu"].as_int();
                let memory = process.resource_usage["memory"].as_int();
                
                // Kill if exceeding limits
                if cpu > 80 || memory > 4096 {
                    let result = admin::kill(
                        process.process_id,
                        "resource_violation: CPU=" + cpu + "%, Memory=" + memory + "MB"
                    );
                    
                    if result.is_ok() {
                        log::audit("monitor", "Terminated agent: " + process.process_id);
                    }
                }
            }
        }
    }
}
```
