The route

Show the step by step (spoilers)

During I've Seen That Face Before, listen to the twins all the way through and read the Blind_n_Dead file. That opens Voodoo Treasure. Head to the shuttered Aesculapius Inc. storefront under the roundabout near the Black Sapphire and open the exterior cache with 941229.

Confirmed by published guides, not yet by Vaexil. Nobody here has walked this one in game, so take it as a strong lead rather than a promise. Cross-checked against CD PROJEKT RED patch notes, VULKK, and the Cyberpunk Wiki, for patch 2.31 with Phantom Liberty.
