the state, tinted by influence

Order A-104 arrived yesterday and the box was crushed on one corner. The jacket itself looks fine, honestly. I've been shopping with you since 2019 and never had a problem before. I'm not sure whether to send it back or just keep it at a discount. Your policy page says damaged items qualify for a full refund. Let me know what my options are.

the smallest evidence that reproduces this answer

0 of 6 segments are enough. On their own they answer 0.9669, against 0.9876 for the whole state.

what would have had to be different

Nothing found that flips value >= 0.5. The decision is robust to removing evidence.

This question cannot discriminate. An empty state already answers 0.9669, which falls on the same side of value >= 0.5 as the full state. Most of the answer is a prior the input never moves, so a threshold here will fire on almost anything — including nothing at all.

can you trust this map

Exact attribution. Every one of the 64 possible combinations of this evidence was evaluated, so these values are not estimates. They sum to the total swing by construction — the +0.0000 residual is floating-point error, not uncertainty.

Interacting and redundant evidence is credited correctly here, which leave-one-out cannot do.
