03
Systems Statement
Resilience is engineered at system level
Infrastructure is treated as an integrated stack of protocol behavior, identity, telemetry, and incident controls. Validation includes degraded-state operation and adversarial misuse scenarios.
Operational behavior under stress
Design assumptions are tested against network instability, dependency failure, and hostile interaction models. Architecture quality is measured by control retention, not nominal throughput alone.
04
Research Alignment
Architecture-informed technical briefs
Research outputs are developed as engineering artifacts to support architecture review, migration planning, and hardening decisions.
