Most of my public work sits at the security-plus-AI-agents seam: isolated runtimes, explicit trust boundaries, capability-gated tools, and automation that leaves evidence behind. The pinned repositories are different implementations of that idea.
Strata preserves the life of durable architecture decisions; Cairn disciplines the implementation work around them. Together they keep design authority and execution evidence inspectable without collapsing design history into session state.
