Don't bolt agentic enhancements onto RAG uniformly.

Agent-Orchestrated Adaptive RAG (arXiv:2606.05658) finds agentic enhancements are not universally beneficial. Dynamic query decomposition gained +0.17 MRR on a structured DevOps benchmark but degraded ranking precision on a multi-hop benchmark, and the self-reflective loop only improved citation accuracy at a real latency cost. The takeaway is cost-aware orchestration: gate decomposition and reflection per query type and domain, and measure the latency tax before you turn them on everywhere. "Add more reasoning" is not a strategy, it's a tax you have to justify per query.
