Dense fits in-distribution 2-hop compositions but fails OOD; both looped recomputation and memory rereading cross this OOD grokking barrier, indicating that repeated shared access -- not a specific architecture -- is the common ingredient for learning. Editing, however, separates the substrates along a different axis.
