The chain that is confirmed
Vos is a Refuge resident. His quest is the practical one: repair the pumphouse, receive the Village Supplies box, open it, and take the old church key that sits inside. The trophy name is Family Found. The Steam flag is VOS_QUEST. He has a unique line in the ending stretch, mentioned in the Better With Friends discussion, which is a sign the line is tracked separately from the box.
This page applies to version 1.0.0.63 and later. That patch fixed quest checkmarks and a set of clue bugs. Earlier saves can show a tick before the box is open. Update, then talk to him again after the pump.
The number this page will not print
The supplies box has a code, and Vos is the person who gives it. No primary source publishes the digits. A secondary page’s single-digit claim is not enough to put a number on a guide. Open the box from his dialogue. If a site sells you a “Vos code” as a store promo, it is describing a system this game does not have.
Show a stronger hint
If he will not talk about the box, the pump is not finished, or you are on a pre-1.0.0.63 save with a bad checkmark.
Show the sourced solution
Fix Elymere pumphouse, talk to Vos, open the Village Supplies box he gives you, take the old church key. Digits are in his dialogue, not on this page.
