✓ Portable graph bundle live · download bundle · merged state

The bundle contains the canonical record plus signed events. A mirror can host it anywhere and recompute the same current state with the deterministic merge algorithm.

Claims

C1strongest claim

explicitly regulating representation geometry effectively mitigates modality trade-offs

C2weakest assumption

That the observed intra-modal collapse and cross-modal inconsistency are the primary geometric pathologies limiting performance and that the proposed regularizers can be added without introducing new optimization instabilities or requiring extensive retuning.

C3one line summary

A regularization method enforces diverse intra-modal embeddings and bounded inter-modal drift to improve both multimodal fusion and unimodal robustness.
