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

Non-symbolic methods such as Shapley values lack rigor and can mislead, while symbolic methods provide rigorous alternatives for feature importance assignment.

C2weakest assumption

That symbolic methods can be made practical and scalable for the complex, high-dimensional models used in real-world machine learning.

C3one line summary

The paper reviews work on symbolic methods for rigorous feature attribution in XAI as an alternative to non-rigorous non-symbolic techniques.
