MIRROR is not a template. It is a live, cost-engineered AI product: a RAG chatbot over my own knowledge base (Grok API + hybrid BM25 retrieval), document upload, web scraping, multi-user sessions — running on a small VPS for under $1/day. The architecture decisions are documented like I would for any client.
