✅ Authorization tests	Comprehensive test suite with 15+ test cases	✅ Complete

🏗️ Architecture Overview

Core Components

1. Data Structures

pub struct ScannerVersion {
    pub version: String,                    // Semantic versioning (x.y.z)
    pub wasm_hash: BytesN<32>,              // SHA-256 hash of WASM binary
    pub vulnerability_db_hash: BytesN<32>,  // SHA-256 hash of vulnerability DB
    pub status: VersionStatus,              // Active, Deprecated, Insecure, Beta
    pub registered_at: u64,                 // Registration timestamp
    pub registered_by: Address,             // Admin who registered
    pub changelog: String,                  // Version changelog
    pub min_stellar_protocol: u64,          // Minimum Stellar protocol version
}

2. Storage Layout

ADMIN: Contract administrator address
VERSION_COUNTER: Total versions registered
VERSIONS: Map<String, ScannerVersion> - All version data
LATEST_VERSION: String - Latest active version pointer

3. Security Features

Admin-only controls for all state-changing functions
SHA-256 cryptographic hashing for integrity verification
Version status tracking (Active, Deprecated, Insecure, Beta)
Event emission for transparency and monitoring

🚀 Key Functions

Admin Functions

initialize(admin) - Set up contract with administrator
register_version() - Add new scanner version with hash verification
deprecate_version() - Mark old versions as deprecated
mark_insecure() - Flag versions with security vulnerabilities
update_vulnerability_db() - Update vulnerability database hash
transfer_admin() - Transfer administrative rights

Query Functions

get_latest() - Get latest active version for CI/CD
get_version() - Get specific version by version string
verify_latest_wasm() - Quick hash verification
get_active_versions() - List all supported versions
get_registry_stats() - Registry statistics

🧪 Testing Coverage

Comprehensive Test Suite (15+ test cases)

✅ Contract initialization and admin controls
✅ Version registration with validation
✅ Hash verification functionality
✅ Deprecation and security marking
✅ Event emission verification
✅ Authorization and access control
✅ Edge cases and error conditions
✅ Version lifecycle management

Test Categories

Initialization Tests - Contract setup and admin configuration
Authorization Tests - Admin-only function protection
Version Management Tests - Registration, deprecation, security marking
Hash Verification Tests - WASM and vulnerability database integrity
Event Tests - Proper event emission for all operations
Edge Case Tests - Invalid inputs, boundary conditions
