vev_0b0483bdfdb68baffinding.caveatedVerifier caution: L5H1 induction head is well-established in Olsson et al. (2022) 'In-Context Learning and Induction Heads' with matching score ~0.96. The reported minimum score of 0.9004 across held-out prompts is plausible. However, cross-replication to distilgpt2 is unverified in published lite
