This puzzle requires the “BATNA” spec record and the One Eden wine bottle label.
The markings on the front of the label seem to be fragments of the shapes Tendi finds on the back of the label.
Without any cutting or tearing, it is possible to make the front of the wine label form the complete shapes Tendi finds on the back of the label. To form shapes on the wine label, you can “curl” the label strategically so that different edges overlap.
When the wine label is made to form one of the complete shapes from the back of the label, the other markings within should take a familiar shape.
The first shape shown on the back of the wine label can be made by curling the wine label so that the bottom left corner overlaps with the bottom right corner. After forming the first shape that Tendi finds on the back of the label, the other markings within the shape form the letter T.
Forming each of the five shapes will result in five different letters taking shape.
ANSWER REVEAL: Forming the first shape results in the letter T being made within it. Forming the second shape makes an O. The third shape makes an X. The fourth shape makes an I, and the fifth and final shape makes an N, all together spelling out TOXIN. Looking at the “olives” envelope, toxin is synonymous with VENOM. So VENOM is the keyword that grants access to the envelope.
