[R] Controlled experiment: giving an LLM agent access to CS papers during automated hyperparameter search improves results by 3.2%

Ran a controlled experiment measuring whether LLM coding agents benefit from access to research literature during automated experimentation. Setup: Two identical runs using Karpathy's autoresearch framework. Claude Code agent optimizing a ~7M param GPT-2 on TinyStories. M4 Pro, 100 experiments each, same seed config. Only variable - one agent had access to an MCP server that does full-text search over 2M+ CS papers and returns synthesized methods with citations.
