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

By utilizing Semantic IDs (SIDs) and a dual-level attention strategy, UxSID captures target-aware preferences without the heavy cost of item-specific models... achieving state-of-the-art performance and a 0.337% revenue lift in large-scale advertising A/B test.

C2weakest assumption

That semantic grouping via SIDs plus dual-level attention actually preserves target-aware preferences better than item-specific search or item-agnostic compression without introducing new biases or losing critical signals in the ultra-long sequences.

C3one line summary

UxSID introduces semantic-group shared interest memory with Semantic IDs and dual-level attention to model ultra-long user sequences, claiming state-of-the-art results and a 0.337% revenue lift in advertising A/B tests.
