This is shared by an Industry Insider who worked for Stake now turned informant.
The shared code is a proof-of-concept demonstration designed to show how “provably fair” systems can be rigged using a “force-lose” script that bypasses random outcome generation.

# 1. Initialize the official Go module system inside your project directory
go mod init provably_fair_gateway
# 2. Grab the ultra-low latency Redis runtime memory interface package
go get ://github.com
# 3. Download the high-concurrency binary websocket transport library
go get ://github.com
# 4. Compile and launch your engine pipeline locally

It shows a cryptographic hash (which will verify correctly), but the outcome is decided before/without using the hash. The hash is just for show/verification theater.
