🔍 3-Tier Verification System

Our GitHub Actions CI/CD pipeline includes comprehensive verification to ensure installer quality:

Tier 1: Package Validation

✓ Platform-specific detection (NSIS/AppImage/PKG)
✓ Size validation (minimum thresholds for embedded dependencies)
✓ File structure verification (PE32/ELF/PKG metadata)
✓ Distribution packaging verification

Tier 2: Integrity Testing

✓ Binary header validation (PE/ELF magic bytes)
✓ Cryptographic checksums (SHA256)
✓ Content validation (component strings)
✓ Non-destructive testing (no installer execution)

Tier 3: VM Dependencies Verification

✓ Embedded component detection (QEMU, VM images)
✓ Platform virtualization support verification  
✓ Payload inspection and validation
✓ VM strategy documentation
