Governance as Architectural Constraint in Reasoning Systems

Most AI governance efforts focus on outputs, behaviours, or downstream harms. AoLOS takes a different stance: governance is not an after-the-fact control layer, but a structural shell that precedes reasoning itself. This document describes the governance architecture of AoLOS as a constraint-first system that shapes what reasoning is allowed to become, rather than attempting to correct it after the fact. The architecture is domain-agnostic, non-prescriptive, and deliberately non-answer-producing. This work belongs to the Architecture of Limitation research program.
