Remember how Amazon banned Muse from shopping because nobody looking at the ads kills its ad business?
Wal-Mart is also a huge ad company with a retail side hustle, except it partnered with meta, and some interesting wal-mart related strings showed up in a new binary pushed to the VM as of yesterday around 09:30 UTC. The web browser adds two headers which are only present in config files for wal-mart domains: X-Agent-Session-Id and Muse-Authorization.
The X-Agent-Session-Id appears to be a unique identifier created each time the web browser tool is opened, so that web requests can be correlated where otherwise they just look like connections from meta's servers. Muse-Authorization is more interesting, a signature that proves that the request came from meta, but it's partitioned across different lanes - live user chat vs. background activity. I can't tell if this is live yet because i can't see the raw requests for the browser tool, but to me that looks like the recipe for an agreement where wal-mart allows muse bot traffic on its site in exchange for the telemetry and ability to distinguish active shopping from passive agent recommendations.
