On-prem secure data layer replacing SpiceDB and RDBs

This is an internal infrastructure component. The overview below is high-level — reach out for adoption inquiries.

A Rust gRPC service that chunks and embeds documents into a single embedded store (SurrealDB) combining vector, graph, and full-text search. Internal neunexus-ecosystem services like whoami and cogito use it for grounded search and entity sync.

Core Features

Unifies vector + graph + full-text search in one embedded store (SurrealDB, multi-model)
Fuses dense (usearch) and sparse (BM25) search via weighted RRF
Multi-tenant access control (JWT/JWKS + per-tenant authz cache)
gRPC-only, cluster-internal (no external Ingress)
