feat(governance): Implement multi-environment policy enforcement

[adwiteeymauriya]

Description

Implement consistent policy enforcement across cloud, on-premise, edge, and hybrid environments.

Environment Types

Cloud

• Characteristics: Elastic, multi-tenant, managed
• Considerations:
  • Data residency requirements
  • Cross-region policies
  • Shared responsibility model

On-Premise

• Characteristics: Controlled, isolated, dedicated
• Considerations:
  • Air-gapped deployments
  • Custom compliance frameworks
  • Legacy system integration

Edge

• Characteristics: Distributed, low-latency, constrained
• Considerations:
  • Offline policy enforcement
  • Lightweight governance agents
  • Sync and conflict resolution

Hybrid

• Characteristics: Mixed, complex, transitional
• Considerations:
  • Consistent policy across environments
  • Workload-appropriate enforcement
  • Unified observability

Features

• Policy distribution with eventual consistency
• Environment-specific policy overrides
• Conflict resolution strategies
• Offline mode with local policy cache
• Sync status monitoring
• Cross-environment audit trail aggregation

Acceptance Criteria

• Policy sync protocol implemented
• Environment-aware policy selection
• Offline enforcement capability
• Conflict resolution logic
• Cross-environment observability
• Edge-optimized lightweight agent
