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

Prompting frontier models with hints of 'where' and 'when' to look yields substantial improvements in performance.

C2weakest assumption

The spatiotemporally-dense human-annotated reasoning traces and object masks accurately capture the intermediate steps and visual elements required to solve the multi-step questions.

C3one line summary

Minerva-Ego is a new benchmark for egocentric visual reasoning with dense human-annotated traces and masks, showing that spatiotemporal hints substantially improve frontier model performance.
