chaotic_semantic_memory 0.3.2

//! # Chaotic Semantic Memory
//!
//! High-performance memory system using **Hyperdimensional Computing** (HDC) and
//! chaotic echo-state reservoir dynamics.
//!
//! ## Encoding Model
//!
//! This crate uses HDC (not transformer embeddings) for text-to-vector encoding.
//! [`encoder::TextEncoder`] converts text via token-level FNV-1a hashing, positional
//! permutation, and majority-rule bundling into 10240-bit binary hypervectors.
//! Similar tokens in similar positions produce similar vectors. For true semantic
//! similarity (synonyms, paraphrases), inject vectors from an external embedding
//! model via [`ChaoticSemanticFramework::inject_concept`].
//!
//! **Turso Vector Alternative**: This crate uses libSQL (local SQLite or remote Turso)
//! for persistence. You can add Turso's native vector search tables (`F32_BLOB` with
//! `vector_top_k()`) alongside the crate's HDC storage in the same database. The crate
//! manages `concepts` and `associations` tables; you manage `semantic_vectors` for
//! float-vector similarity search.
//!
//! ## Concurrency
//!
//! The framework uses `tokio::sync::RwLock` internally and is safe to share
//! across async tasks via `Arc`. SQLite persistence uses WAL mode for concurrent
//! reads. All public APIs are async — do not wrap in `block_on` inside a Tokio runtime.
//!
//! ## WASM Parity
//!
//! Most APIs are available in WASM. Exceptions:
//! - `Persistence`: Replaced with stubs in `persistence_wasm`
//! - `process_sequence`: No Rayon parallelization in WASM
