A developer encountered a critical bug in their custom AI agent's memory system where facts were not being embedded due to a silent truncation issue in the FastEmbed library. The library's default 512-token limit was cutting off large sections of text, leading to missing data and failed retrieval. The developer devised a method to prove the truncation was the cause, rather than centroid dilution, by measuring embedding distances and identifying a sharp cliff at the truncation point. The ultimate fix involved parsing the memory file to embed each fact individually, ensuring all facts fit within the model's supported window, and implementing a warning system to prevent recurrence.
