VARZIN V2 — Recoverable but Not Composable: Representation Recovery and Systematic Composition in a Frozen Language Model

This research report presents the integrated Phase 0–2 results of VARZIN V2, an experimental study of the relationship between structural representation recovery and systematic compositional generalization in a frozen language model. The study asks whether a structural variable t...

Morphological Hijacking in Frozen Language Models: Recovering Structured Representations and Testing the Limits of Algebraic Composition

This revised manuscript presents a controlled study of morphological hijacking in frozen language-model representations using the synthetic LUXVAR/VARZIN framework. The study shows that adversarial surface structure can dominate frozen representations, while a lightweight trained...
