We respond to the invitation extended in "Brittleness in Mature Coupled Systems: A Structural Hypothesis" (Project Recursion, 2025) by offering clarifications and refinements to the proposed framework. While we find the core hypothesis directionally sound, several definitions require tightening, and the central mechanism—that retroactive structural modification constructs a new coupled system rather than adjusting an existing one—deserves more explicit treatment. We suggest reformulations that preserve the hypothesis's explanatory power while improving its precision and falsifiability.
