Key features	Hybrid search combining BM25 lexical and vector scoring Vertex graph vector index with 2.29-2.75x throughput vs hnswlib Vector-symbolic fact memory with holographic reduced representations AES-256-GCM encryption at rest with Argon2id key derivation Signed audit log with Ed25519 and W3C DID identity Secure purge that overwrites deleted data with zeros Crash-safe append-only log with checksumming Native Rust API with Python HTTP client and Node.js bindings MCP server integration for editors and AI agents WARM Cloud sync, backup and verification without server access to keys or documents	Isolated Firecracker microVMs with own kernel and filesystem Background jobs that survive disconnects Batch execution with up to 1,000 jobs and dependency passing WebAssembly jobs starting in milliseconds without VM boot Budget Guard with cost reserves and limits Execution receipts with runtime, isolation, resources and file hashes Native MCP server integration for ChatGPT and Claude Compact log digests instead of full 5,000-line logs Server-side job waiting with signed webhooks Verified package cache for PyPI, npm, Go and Rust
What makes it different	Runs entirely locally in your process with no network calls or telemetry Encryption at rest built into the open-source engine itself, not an enterprise add-on Significantly faster vector search than hnswlib with graph-indexed vertex retrieval Signed provenance and verified audit trail using C2PA, COSE and SCITT standards Embedded library model eliminates dependency on external services or vendor lock-in	Two runtimes with honest isolation labeling
