Code protection secretly removed from an embedded software by a local LLM

I requested an LM Studio hosted local Qwen 3 Coder 480B Q4 (which is one of my favourite models for complex tasks) to update an assembly source code of an embedded system, specifically a code for a Microchip PIC16F882 microcontroller. I used Kilocode extension for VS Code as the agentic framework and gave access to the markdown converted version of the originally 288 pages long datasheet of the microcontroller to the model.
