Proof on real public data
The engine finds the same cause in a language it was
never given.
We trained a structural bridge on ~250 example links between two
incident records that share no vocabulary, format, or industry — NASA
aviation safety reports and federal pipeline filings — then, for
aviation incidents it had never seen, asked it to retrieve the
pipeline accidents with the same underlying cause.

Retrieval accuracy is the reportable number. The working measure is
agentic behaviour — whether an agent carrying this
memory does the task better. That is what an internal agent gym scores,
and what the research is steered by.
