post-cortex-embeddings 0.3.1

Embedding engines (Model2Vec static + BERT via Candle + static-hash fallback) and HNSW vector database for post-cortex. Self-contained ML stack — depend on this crate when you need vector search without the full post-cortex orchestrator.

//! HNSW vector database — types + impl.
//!
//! [`types`] is dependency-light (only `serde`, `chrono`, `uuid`,
//! `std::sync::atomic`). The HNSW index + product-quantization codebook
//! live in private modules and are reachable through the [`VectorDB`]
//! entry point. Storage backends that only need to round-trip
//! [`VectorMetadata`] and [`SearchMatch`] can depend on
//! `post-cortex-embeddings` with `default-features = false`, which
//! compiles only this `types` module.

pub mod types;

// HNSW impl modules. Behind the `bert` feature today via the rest of the
// pipeline; we keep them unconditional so non-BERT consumers can still
// build the HNSW path with a custom embedding backend.
