Sparse Distributed Memory ≈ Attention

The engine is Kanerva's SDM, first described at MIT. Recent work (2021–2026) proved it is mathematically equivalent to the Attention mechanism inside Transformers — the very thing that powers GPT-4 and Claude.

So this isn't exotica bolted onto an LLM. It's the same principle, exposed as durable, write-once-recall-forever memory the model can reach through MCP.
