Lost Arthur/Eames fic [inception]

This is a long shot - i’m searching for a fic that wasn’t on AO3. I have this link, but it’s no longer working for me

Basically, it was a fic where Arthur and Eames had some sort of bet. I can barely remember the plot, but I’m hoping someone can work out from the link itself what fic it was?? like if anyone remembers a fic being recced that only had a box.com link?

In another sense, there’s no reddit page for the Inception fandom, which is small and maybe dead now, but are there any Arthur/Eames fans still out there? I ask because I genuinely believe this was the best fandom of all time with the BEST fanfics ever written, like pulitzer prize level
