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

TriAlignGR resolves both SID Content Degradation (SCD) and SID Semantic Opacity (SSO) through three tightly integrated components: Cross-Modal Semantic Alignment (CMSA), Multimodal Deep Interest Mining (MDIM), and Triangular Multitask (TMT) that jointly trains on eight complementary generation tasks including two novel visual-semantic tasks.

C2weakest assumption

That VLM-generated descriptions and multimodal embeddings preserve critical semantics without introducing new noise or bias, and that joint training on the eight tasks improves rather than interferes with the core generative recommendation performance.

C3one line summary

TriAlignGR integrates visual content and latent user interests into Semantic IDs via cross-modal alignment, CoT-based interest mining, and triangular multitask training to address content degradation and semantic opacity in generative recommenders.
