I write architecture docs, compliance narratives, and constitutional specifications for governed AI systems — translating engineering work into standalone-readable artifacts for regulators, platform teams, and hiring reviewers.

Twenty years from network infrastructure through iOS and software architecture to AI governance. AgentVector is the framework; this site is the writing portfolio and the production proof.

Governance defined

Governance defines what the agent may do, what it may never touch, what requires human escalation, how evidence is recorded, and how decisions are replayed and audited. It is not a behavioral prompt. It is a structural constraint — enforced before execution, not after.

The framework

Four Law groups. Eleven Laws in the Codex. Language-specific enforcement kernels. Domain jurisdictions that apply the Laws to specific operational contexts.

AgentVector Codex
Constitutional framework for governed AI systems

Eleven Laws in four groups. The reducer pattern, evidence chain structure, and composability rules for jurisdiction design.

Enforcement Kernels
Web overview · language-specific runtime guarantees

SwiftVector · TSVector · RustVector. Each kernel compiles Laws into language-specific guarantees — actor isolation, pure functions, ARC memory management.

Composable Laws
Policy primitives that adapt by operational domain

Observation, Resource, Spatial, Authority — domain-agnostic primitives that compose differently per jurisdiction while remaining architecturally identical.

Why governance-first

The governance layer is not an afterthought bolted onto an existing AI system. It is the foundation on which the AI system is built. Policy is defined before the first agent call. Every action is evaluated before execution. The constitutional architecture means the system can demonstrate compliance on demand — not merely claim it.

The same Laws.
Different operational contexts.

The constitutional architecture composes differently across aviation, desktop agents, and narrative AI. Same kernel pattern. Replayable evidence in every jurisdiction. Writing samples indexed at /portfolio →

FlightLaw · SwiftVector + RustVector
Flightworks Sentinel

AI can propose. Flightworks Sentinel decides. The record proves it. Sits between your AI layer and your autopilot — governing what AI is permitted to propose, issuing typed verdicts, and preserving replayable evidence of every decision.

Active development
Vigil · SwiftVector
Light Station

Operator console for governed AI systems. Persistent operating picture of agent proposals, policy verdicts, evidence chains, and human escalations — across any AgentVector jurisdiction.

Reference implementation · v0.2.0
Chronicler · SwiftVector
Chronicle Quest

Human authorship protected as a formal governance constraint. AI may draft prose; it cannot decide fate.

Active development

Where to start.

Stephen Sweeney architects and governs autonomous AI systems, based in Monument, CO. A career that moved from network infrastructure through iOS development and software architecture arrived here by following one question: how do deterministic systems maintain authority when acting in probabilistic environments?

AgentVector, the writing on this site, and the work at Flightworks Systems are all answers to that question — built from first principles and tested in production.
