DVA (Decentralized Verification Architecture)

Overview

DVA is the core verification mechanism that ensures integrity across all operations. It operates across four tiers:

Tier 1: DVA Lite - Single verification engine - Fast, lightweight verification - Suitable for development and testing - SLA: 99.0%

Tier 2: DVA One - Dual verification with consensus - Production-grade reliability - Feedback loop integration - SLA: 99.5%

Tier 3: DVA Full - Multi-engine verification - Full consensus protocol - Advanced recovery mechanisms - SLA: 99.9%

Tier 4: DVA Hive - Distributed global consensus - Maximum integrity guarantees - Cross-datacenter coordination - SLA: 99.95%

See: dva/DVA_MEMT_INTEGRATION.md

MEMT (Multi-Engine Model Taxonomy)

Overview

MEMT orchestrates multiple AI models to achieve consensus on critical decisions:

Supported Engines: - OpenAI GPT-4 (AUREA sentinel) - Anthropic Claude (ATLAS sentinel) - Open-source models (configurable)

Consensus Algorithm: 1. Task decomposition 2. Parallel engine invocation 3. Response aggregation 4. Trust-weighted voting 5. Consensus verification

Trust Weights: - Based on historical accuracy - Domain-specific expertise - Integrity track record - Updated continuously

See: memt/ for MEMT documentation

Integrity Ledger

GI Formula

GI = 0.25 × M + 0.20 × H + 0.30 × I + 0.25 × E

Where:
M = Memory (test coverage, documentation)
H = Human (code review, collaboration)
I = Integrity (security, no violations)
E = Ethics (charter compliance, virtue tags)

Threshold: GI ≥ 0.95 required for all commits

See: ledger/gi-formula.md

Labs Architecture

Lab Structure

Each lab implements: 1. Frontend: User interface (React/Next.js) 2. Backend API: Business logic (Node.js/Python) 3. Database: Persistent storage (PostgreSQL) 4. DVA Integration: Integrity verification 5. MEMT Integration: AI-assisted operations

Communication

  • Inter-lab: REST APIs
  • Lab ↔ DVA: Event-driven
  • Lab ↔ MEMT: Request/response with streaming

See: overview/technical/LABS_MASTER_ARCHITECTURE.md

Security Architecture

Security Layers

  1. Authentication: OAuth 2.0 + JWT
  2. Authorization: Role-based access control (RBAC)
  3. Encryption: TLS 1.3 in transit, AES-256 at rest
  4. Audit: Immutable audit logs
  5. Integrity: Continuous GI monitoring

Threat Model

  • External attacks: Mitigated by WAF + IDS
  • Insider threats: Prevented by RBAC + audit
  • Data breaches: Protected by encryption + anonymization
  • System compromise: Detected by DVA + monitoring

See: ../06-OPERATIONS/security/ for security documentation

Scalability

Horizontal Scaling

  • Stateless services (easy to replicate)
  • Load balancing (NGINX/ALB)
  • Database read replicas
  • Cache distribution (Redis Cluster)

Vertical Scaling

  • Database optimization
  • Query optimization
  • Connection pooling
  • Resource allocation tuning

Performance Targets

  • API response time: < 100ms (p95)
  • Page load time: < 2s (p95)
  • DVA verification: < 500ms (p95)
  • MEMT consensus: < 2s (p95)
