THE ROADMAP
456more operating alphabets are benchmark addition candidates

Every released FSI is a future L26 track.

BantuNomics has released 459 FSIs — each the complete, independently established operating alphabet of one Bantu language. 3 of them (Bemba, Kinyarwanda, Luvale) are on today’s board. The other 456, across 16 Guthrie zones, are candidates for future versions of L26 — each to be scored on its own inventory, under the same strict PASS / FAIL rule.
