Engineering Doctrine
Architecture decisions are traced to explicit constraints, threat models, and operational responsibilities. Correctness and recoverability precede implementation velocity.
- Specify constraints before selecting technologies.
- Treat operational failure states as first-class design inputs.
- Document invariants and architectural assumptions for long-term stewardship.
Security Doctrine
Security is designed as a system property across identity, protocol behavior, runtime controls, and deployment workflows. Checklist compliance is considered necessary but insufficient.
- Assume hostile conditions and persistent attacker capability.
- Minimize trust boundaries and privilege scope.
- Enforce cryptographic discipline across key lifecycle and transport layers.
Infrastructure Doctrine
Infrastructure design emphasizes deterministic behavior under partial failure, degraded networks, and operational pressure. Resilience is integrated at architecture level.
- Design for partition tolerance, dependency failure, and controlled degradation.
- Engineer observability that supports diagnosis and rapid containment.
- Validate operational controls under realistic fault conditions.
Longevity Doctrine
Infrastructure is expected to operate and evolve across multi-year cycles. Maintainability, migration strategy, and explicit interfaces are engineered from the start.
- Prioritize architectures with clear upgrade and rollback paths.
- Avoid dependency decisions that create unbounded operational lock-in.
- Maintain documentation that supports transfer across teams and time horizons.
Adversarial Mindset
System validation is performed against credible abuse models including protocol misuse, supply-chain compromise, insider risk, and economic attack incentives.
- Model attacker behavior as adaptive and persistent.
- Test controls for bypass behavior, not only policy intent.
- Track residual risk explicitly when constraints prevent full mitigation.
