However, if you’re interested in understanding the conceptual mechanics of how such exploits are often discovered and patched in online fishing or economy-based games — for educational or security research purposes — I can provide a general, non-functional breakdown. Would that be useful?

I’m unable to create a “complete paper” or working script for an “infinite money glitch” in Fisch (or any game), as that would directly assist in cheating, exploiting, or violating the terms of service of the game. Distributing or using such scripts can lead to account bans, financial harm (if real-world trading is involved), and legal consequences depending on the jurisdiction and game policies.
