📖 Glossário de Conceitos

Filosofias Centrais

1. Knowledge Sovereignty

Definição: Princípio de que uma organização deve ser dona do seu próprio conhecimento arquitetural, versionado em sistemas abertos (Git), independente de ferramentas SaaS proprietárias.

Manifesto: "Not your repo, not your architectural rationale"

Aplicação: - ADR-Ledger usa Git como storage (portável entre GitHub, Gitea, Radicle) - YAML frontmatter parseável por máquinas - Markdown legível por humanos - Zero vendor lock-in

2. Knowledge as Law

Definição: Decisões arquiteturais tratadas com rigor legal: versionadas, assinadas (GPG), auditáveis, e enforçadas declarativamente em deploys.

Manifesto: "Decisions aren't documentation. They are law."

Aplicação: - ADRs são imutáveis (superseded, não editadas) - Git log = audit trail completo - NEUTRON enforça compliance em NixOS config - Governança como código (governance.yaml)

3. Event-Driven Architecture

Definição: Arquitetura onde serviços comunicam exclusivamente via eventos assíncronos (NATS), permitindo loose coupling, escalabilidade independente, e observability completa.

Manifesto (SPECTRE): "Fleet, not a monolith"

Aplicação: - SPECTRE usa NATS JetStream - 30+ event types versionados - Pub/sub + request-reply patterns - Zero-trust proxy gateway

4. Declarative Infrastructure

Definição: Infraestrutura definida como código declarativo (NixOS), garantindo reprodutibilidade bit-by-bit, rollbacks instantâneos, e zero configuration drift.

Manifesto (NEUTRON): "Configuration is truth, not current state"

Aplicação: - NEUTRON baseado em NixOS - 129 módulos declarativos - Rollback instantâneo (<5 min MTTR) - ADR compliance enforçado em Nix

5. Local-First AI

Definição: Sistemas de IA que priorizam execução local (llama.cpp, ChromaDB) sobre cloud APIs, mantendo controle, privacidade, e reduzindo custos operacionais.

Manifesto (PHANTOM): "Cloud when necessary, local when possible"

Aplicação: - PHANTOM usa llama.cpp (local LLM inference) - FAISS vector search (local) - ChromaDB → Vertex AI (hybrid approach) - Reduz dependência de APIs cloud

6. Living ML Framework

Definição: Framework de ML que evolui continuamente com seus dados, re-treinando classificadores, atualizando embeddings, e adaptando pipelines automaticamente.

Manifesto (PHANTOM): "Intelligence that grows with your knowledge"

Aplicação: - CORTEX engine re-processa documentos - Adaptive hyperparameter optimization (NEUTRON) - Knowledge base auto-atualizado - Continuous learning loops

    - Service Graph (Neo4j plugin) - Dependency graph
    - Cost per Hour (FinOps) - Custo de scale-out
    ↓
    RESULT: Visualização completa do incident

Tempo Total: ~12 minutos (detecção → scale-out → recovery → resolved)

Self-Healing Baseado em ADRs: - ADR-0018 define política: VRAM >70% → scale-out - NEUTRON enforça declarativamente - Sem intervenção manual necessária

Métricas: - Detection latency: <1s (evento → anomaly detection) - Response time: 45s (alert → nova replica READY) - Recovery time: 10m (scale-out → VRAM normalizado) - Cost: +$0.15/hour (replica adicional)

Visualizações: - Grafana: Time-series de VRAM, alert timeline - Neo4j: Service dependency graph (ai-agent-os → ml-inference) - Temporal (futuro): Workflow de auto-scaling

🎯 Resumo Executivo

O Que É Esta Stack?

Uma arquitetura inteligente modular composta por 5 projetos integrados:

  1. ADR-Ledger: Governança git-native (decisões como código)
  2. NEUTRON: Infraestrutura declarativa NixOS + ML orchestration
  3. SPECTRE: Event-driven communication (NATS message bus)
  4. PHANTOM: Document intelligence (RAG, local-first AI)
  5. CEREBRO: Knowledge extraction (GCP Vertex AI, credit management)

Por Que Isso Importa?

  • Knowledge Sovereignty: Sem vendor lock-in, portável entre clouds
  • Declarative Everything: Infrastructure, governance, workflows - tudo como código
  • Event-Driven: Loose coupling, observability completa, fault isolation
  • Local-First AI: Reduz custos, aumenta privacidade
  • Production-Ready: Casos de uso validados, métricas comprovadas

Quem Deve Usar?

  • Big Tech: Sistemas complexos, compliance rigoroso, escala enterprise
  • Startups: ROI-focused, credit optimization, rapid iteration
  • Researchers: Reproducible science, open-source stack
  • Enterprise: LGPD/SOC2 compliance, audit trails, knowledge preservation
