Hyphae
One process owns one local data directory and exposes bounded relational SQL, native structures, lexical search, and vector search over a shared transaction, WAL, MVCC, recovery, and proof substrate.
Boundary. Hyphae does not include replication, clustering, built-in TLS, at-rest encryption, a hosted control plane, an embedding model, or an LLM. “Proof” means verification against the documented commitments and rules; it does not establish that input data is true.
