  A framework the paper uses alongside feature geometry to deepen mechanistic understanding of LMs
• Causal abstraction analysismethod0.801
  The formal method used to establish that the identified circuit causally mediates the model's cyclic reasoning behavior
• Causal abstraction is not enough for mechanistic interpretability because it becomes vacuous without assumptions about how models encode informationclaim0.798
  Central thesis of the paper
• Early causal abstraction methods (Geiger et al. 2021) implicitly rely on the privileged bases hypothesis, while recent methods (Geiger et al. 2024b) rely on the linear representation hypothesisclaim0.787
  Historical framing of how representation assumptions have evolved in causal interpretability
• Constructive Causal Abstractionconcept0.781
  Formal definition: H is a constructive abstraction of L under alignment Π when interchange interventions have equivalent effects at both levels.
