University teaching and development lack a shared vocabulary for deciding which generative-AI model fits which use. This paper proposes user-grounded fidelity probes (here, probe means a diagnostic task whose answer the user already holds, not linear probing of internal represent...

Faithful on Prose, Unanchored on Reasoning: A Position-Domain Calibration of the Jacobian Lens
The Jacobian lens (J-lens) reads which tokens a language model is positioned to verbalize, and its released artifacts are being inherited as defaults. Those artifacts are fitted with a maximum sequence length of 128 tokens, a setting that appears in the distributed configuration...

FidelityEight: Frozen-Protocol Fidelity Measurements of the Distributed Jacobian-Lens Checkpoints
The Jacobian lens ("jlens"), released 2026-07-02 as companion code to the *Verbalizable Workspace* paper, ships with pre-fitted checkpoints for ~36–38 model families. To our knowledge — a bounded-absence claim; see §6 for the search scope — no direct lens-versus-model fidelity me...
