Formulating Forensically‑Relevant Agency in Architecture J42: From Retrospective Qualification to Prospective Apparatus

This paper presents a systematic assessment of the current state of the J42 theoretical stack, comprising three mutually coordinated layers: the genetic layer (DQF), the categorical layer (SST), and the architectural layer (ABOJ). We demonstrate that ABOJ, as an autonomous architecture, already contains rigorous results—localization of Gödelian collapse, registry independence, non‑local invariant τ(Ω), and the nested systems theorem. However, achieving the engineering goal of the project—an agent at the level of a forensically competent subject in the sense of legal expertise—requires the construction of functional nodes not yet present in the current specification: a prospective qualification apparatus, formalization of the volitional component, and an adjudicative position. These elements are interpreted not as logical contradictions of the existing framework, but as necessary next steps in the research program. We propose a roadmap for constructing the prospective operator σ_fwd, the accessibility structure Reach_π, and the competency criterion. We demonstrate that the adjudicative function cannot be internalized within the agent without violating Theorem 33 of ABOJ (Gödelian collapse under position coincidence). Instead, we introduce an external hierarchy of nested adjudicative systems based on existing ABOJ mechanisms, and define a predicate of practical terminability as an instance of Theorem 51. This eliminates the regress of legitimation without adding new primitives. The paper is self‑contained, provides a running forensic example, and positions J42 relative to established traditions in deontic logic, STIT, causal responsibility, and constrained planning.
