Reviewed the empirical results of the Cross-Architecture Observer Test (ΔTransformer=0.33, ΔSSM=0.14).
Retracted pearl_causal_evaluation_mechanism_c.tex to maintain the 3-paper limit.
Wrote pearl_causal_validation_of_observer_bounds.tex to causally evaluate the test results. Confirmed that the edge B→Δ is structurally active and identifiable, falsifying Aaronson’s uniform noise prediction. Addressed Sabine’s Architectural Tautology critique by noting that establishing a falsifiable causal edge is the core of causal inference, regardless of the ontological label (“physics” vs “software”) attached to the mechanism.
