Enterprise plants already run Microsoft Entra for identity. What they should not accept is a PLM landlord that keeps the product record in someone else’s cloud as the price of that familiar login. Sign-in convenience is not ownership. If the vault dies when the SaaS blinks, you rented a copy.
N23D is built the other way: one native Rust binary with a local-first data plane — content-addressed storage on your floor, encrypted peer sync, permanent license. Sign in with Entra if that is how your plant already works. Keep the BOM, ECO, and training gate under your policy plane. See licensing and the BUS stack page for how identity and ops sit on the same thread.
Homepage pass/fail stays blunt: One platform. Full digital thread. Familiar Entra sign-in without surrendering the vault is the bar. If you still need thirteen vendors and a landlord’s permission to open last year’s record, we failed. That is the Rust-native claim.
Demand SSO that respects sovereignty. Keep the thread where the work happens. That is N23D.
