Lineage Clarification (2026):This document reflects a pre-Horizon Rebuild governance framing of the Architecture of Limitation. Subsequent clarification re-established kernel precedence over execution-layer governance. Readers should consult the correction note (DOI: [insert DOI]) for the updated architectural hierarchy. This document provides a public lineage note for the Architecture of Limitation (AoL), clarifying its architectural development, scope, and governance boundaries. It is intended as an interpretive anchor for readers engaging with the AoL research corpus. AoL, as expressed in the v43 kernel, is an architecturally stable constraint grammar. It did not evolve through application, stress-testing, or domain expansion. Across all published analyses, v43’s behavior remains invariant: it evaluates admissibility and, where necessary, contracts, refuses, or withdraws. What has evolved over time is AoLOS — the operating and stewardship shell built around the invariant AoL kernel. AoLOS records how v43 is applied, governed, and publicly expressed without distortion, and how permissive interpretations, optional governance states, and soft-fail affordances are progressively removed in response to misapplication risk. The lineage described here therefore documents adaptations of the operating shell, not changes to the kernel itself. This distinction is essential to prevent misinterpretation of AoL as a developing theory or normative framework. This note introduces no new claims, mechanisms, or extensions. It exists solely to preserve architectural clarity, boundary integrity, and proportional interpretation of the AoL corpus. For domain-specific analyses conducted under AoL, this record should be treated as the canonical reference for architectural lineage and kernel/shell distinction. This work belongs to the Architecture of Limitation research program.
