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 v2 expands the morphological-hijacking study around an adversarial LUXVAR Core-30 lexicon in which salient surface form is deliberately placed in conflict with algebraic orbit structure. The deposited description reports near-total prefix recovery under unsupervised clustering while the target orbit structure is not recovered in the frozen baselines, then investigates anisotropy, token-length effects, and trained remediation. The record therefore combines a negative frozen-model result with a separate intervention result.
Research question
Does the v1 failure pattern persist under a more explicit adversarial lexicon and additional diagnostics, and which representational factors help explain the dominance of surface form?
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 v2 record strengthens the separation between surface-form clustering and algebraic target recovery, while adding diagnostics intended to explain the failure mode. The project does not treat trained recovery as equivalent to spontaneous structure recovery.
Version v2 is a distinct public deposit dated 2026-09-02. It should be cited separately from v1 and v3 whenever version-specific methods or results are discussed.
