MCP VPC Validation Framework - Enterprise Quality Gates

Comprehensive MCP validation framework for VPC cleanup initiatives with
≥99.5% accuracy requirements, evidence bundle generation, and quality gates
enforcement across 60+1 AWS Landing Zone validation.

**Strategic Alignment**: Supports enterprise quality gates with evidence-based
validation, SHA256-verified audit trails, and comprehensive cross-validation
against AWS APIs for VPC security posture enhancement initiatives.

**Quality Framework**:
- MCP cross-validation ≥99.5% accuracy requirement
- Real-time AWS API validation and comparison
- SHA256-verified evidence bundle generation
- PDCA quality gates with comprehensive console log analysis
- Multi-dimensional validation (dependency, architecture, compliance)
- Enterprise audit trail generation with regulatory compliance

**Validation Scope**:
- VPC dependency analysis validation
- Architecture compliance verification
- Security posture assessment validation
- Cost impact projection verification
- Network topology impact validation
- Business risk assessment verification
