It is unpredictable because there are so many permutations. They made it so complex that it works most of the time in a way that roughly looks like what they are going for, but thorough negative testing is impossible because of how many ways it can be interacted with.


The randomness itself isn’t the direct cause of the topic in the post though, because otherwise it wouldn’t be possible to reproduce the steps to get around any guardrails the system has.
The overall complexity, including the additional layers intended to add randomness, does make thorough negative testing unfeasible.
