Technical documentation, deployment runbooks, security whitepapers, and operational guides for the LakeX Sovereign DataVault platform.
Handles relational database sources. LVS agent, Trino, Iceberg REST catalog (datagen-catalog), and PostgreSQL 16 on each Stratum-S node.
Handles file-based sources. LVUS agent, Qdrant vector store, Ollama embedding model, and Iceberg REST catalog on each Stratum-US node.
Per-file metadata tracker storing sort column bounds (min/max). Enables file-level pruning at query time — before Trino opens any file.
FastAPI-based Iceberg REST catalog deployed per-Stratum. Trino connects to it for Iceberg table metadata. Backed by per-Stratum PostgreSQL 16.
Pure function that inspects table schema and returns the optimal sort column and strategy (single, Z-order). No DB access — fully unit-testable.
A DEK (Data Encryption Key) encrypts the data; the DEK is then wrapped by the KEK (master key) from the active crypto provider (HSM, Vault, KMS, or software).
The PQC hybrid construction concatenates ML-KEM-768 and X25519 shared secrets, then runs HKDF-SHA-512 — endorsed by IETF PQUIP WG for TLS 1.3 PQ hybrid.
Phase 1: NER index lookup (entity exact match). Phase 2: SQL query over structured archives. Phase 3: Qdrant semantic vector search over unstructured.
