Deployment Model

One File, Zero Infrastructure

A SERAPH store is a single .sfg file. Header, write-ahead log, append-only frame log. No database server, no cloud dependency, no sidecar files, no schema migrations. Copy it, email it, sign it, notarize it, archive it, or hand it to a verifier who has never seen it before.

Embedding Model Locked at Genesis

The model is declared once and bound into every watermark. A SERAPH store cannot silently absorb embeddings from a different model. The failure mode that silently corrupts every other hybrid system is made impossible. Change the model, rebuild the store. That's correct and intentional.

Single Writer, Universal Read

One designated writer owns all ingests. All other consumers have read-only access — query, traverse, verify. Read access requires no coordination; concurrent readers are safe against an append-only log. Write throughput is bounded by the writer, which can queue, batch, and deduplicate. Semantic memory writes are not a high-frequency hot path.
