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

PGCMs match the predictive performance of state-of-the-art CBMs while substantially improving transparency, interpretability, and intervenability.

C2weakest assumption

That learned visual prototypes can serve as explicit, verifiable evidence for human-intended concepts and support effective targeted interventions at the prototype level.

C3one line summary

Prototype-Grounded Concept Models ground concepts in learned visual prototypes to enable verifiable alignment and targeted interventions, matching Concept Bottleneck Model performance with improved transparency and intervenability.
