Autonomous source-to-exploit research. One rule: nothing gets reported unless a deterministic test could reproduce it.

Darwin unifies several retrieval systems that already worked in isolation and gives them one interface, a capture inbox, and a freshness discipline.
Every previous attempt at this built a retrieval engine and called it a brain. A retrieval engine is a hippocampus. A second brain is a hippocampus plus a front door plus a capture habit plus a way of aging out what is no longer true.
The named failure mode is that a static brain rots, and stale facts look exactly like true ones. This is not hypothetical. During the build itself, an agent confidently reported the live status of two projects that had been dead or parked for weeks, because it read its own memory and nothing in that memory had decayed.
So the thesis is knowledge under selection pressure. Facts carry freshness. Facts that stop being reinforced lose standing rather than sitting at full confidence forever. The retrieval quality was never the bottleneck. Confidence in stale retrieval was.
Roughly four fifths of the capability already existed across separate tools. Treating this as a new research project would have produced a fifth engine and the same problem. The work is connective tissue and a front door.
