Can SpareGraph solve real obsolete-parts problems?

We tested SpareGraph against ten historical industrial packaging-machine problems where the real-world solution was already documented. During each test, the original solution source was excluded from research. The blind result was submitted and locked before the historical solution was revealed.

The Historical 10 case write-ups have not been published yet.

Methodology note. Original answer sources were blacklisted during blind research; only independent evidence was used. Results were locked before the Answer Packs were opened. The historical solution and the 2026 recommendation are evaluated separately. These tests validate the sourcing and evidence workflow — they are not claimed to be a perfect zero-knowledge academic benchmark. See Methodology.
