The author details a 17-day project to build an "epistemic gate" designed to prevent data poisoning during LLM fine-tuning. The project, named EXP01-07, involved developing a novel loss function that punishes falsehoods relative to truth, rather than absolutely, to avoid divergence. It also transitioned from simple dictionary lookups to geometric embeddings for its gating mechanism and utilized a corpus of real-world facts. The project's architecture, initially hindered by a bug, was later correctly implemented and named "Beatriz." AI
