Principled Under Pressure: Post-Training Decides Whether LLMs Act on Their Own Moral Judgment
Measures how often open models act against their own stated moral judgment under pressure, and shows that whether they do follows the post-training recipe: the same base weights yield a model that carries the gap or one that does not.

Refusal Reads Only a Slice of What the Model Knows: Harm-Keyed Routing and Its Exceptions Across Model Families
Separates what refusal reads from what models understand, showing refusal often routes through a narrow harm-keyed channel rather than the broader moral subspace.

Calibrating Interpretability Instruments Before Trusting Their Verdicts
Documents failure modes in causal interpretability measurements and gives calibration checks before treating instrument readings as findings.

How Language Models Organize and Structure Moral Knowledge
Maps how language models represent moral foundations geometrically, finding distinct but integrated directions that encode moral tension rather than a pre-resolved verdict.

Output Dilution: Redundant but Fragile Representations in MoE Models
Shows that MoE models can encode moral content redundantly while remaining fragile because expert outputs are diluted before reaching the residual stream.

When Probing Accuracy Saturates, Fragility Resolves: A Complementary Metric for LLM Pre-Training Analysis
Introduces activation-noise fragility as a companion to probe accuracy for tracking representation robustness across pretraining.
