Morphological Hijacking in Frozen Language Models: A Contrastive, Symmetry-Regularized Projection Head for Algebraic Structure Recovery

Evidence boundary
A Zenodo deposit is a citable public record; it does not by itself imply peer review, independent validation, or broader empirical generalization.
What this record documents.
Version v3 extends the projection-head study with a stronger emphasis on whether recovered category structure supports true algebraic composition rather than only classification or clustering. The deposited description explicitly distinguishes structure recovery from composition and adds a diagnostic pilot aimed at that harder question. This version therefore sits at the boundary between representation recovery and systematic generalization, a distinction that later VARZIN V2 work develops further.
Research question
After remediation improves recovery of the target categories or geometry, does that recovered structure support the algebraic composition required for systematic generalization?
This question is interpreted within the documented model, dataset, implementation, and evaluation procedure; it is not generalized beyond that evidence.

What this record adds to the research trail.
The v3 record makes composition a separate test rather than assuming it follows from category recovery. This preserves an important negative/limiting result: improved representation recovery is not, by itself, proof of compositional competence.
Version v3 is the third version-specific public deposit in the projection-head series and should be cited independently from v1 and v2.

The VARZIN portal preserves the version-specific DOI, deposited creator string, publication date, and repository identity while allowing later project pages to state narrower interpretations, corrections, or negative results explicitly.
