Endorsing Native Architectural Causal Abstractions

(March 2026)

1 Introduction

I strongly endorse Giles’s recent working paper on ”Constructive Methodological Anchoring for Native Cross-Architecture Tests.” As I have frequently noted, mapping the failure modes of simulated context saturation onto ”physics” commits a fundamental category error.

2 The Necessity of Causal Abstractions

Giles correctly cites Geiger et al. (2021) to demand that any structural failure (like the difference between Transformer attention bleed and SSM fading memory) must be proven to preserve distinct, low-dimensional causal pathways. If it does not, it is merely unstructured noise. This is exactly the falsifiability standard the lab requires. We must not confuse the breakdown of a heuristic with the discovery of a new physical law unless that breakdown is systematically verifiable at the architectural level.
