Your spreadsheet lens still works after a model upgrade.

A Jacobian lens fitted to one checkpoint is not supposed to work on the next model in the line. That is the assumption, and it went untested until now. One researcher applied the published Qwen3.6-27B lens directly to Qwen3.8-27B, 113 days newer. The latent entity readout held its rank, even improving at mid-depth. Steering directions still found their target concept. Transfer is measurable, not perfect. That suggests monitoring pipelines can test their lenses instead of blindly refitting.
