plugmem-core 0.9.0

#![doc = include_str!("../README.md")]
//! plugmem engine core.
//!
//! The `no_std + alloc`, single-threaded memory engine on top of
//! [`plugmem_arena`]: the data model (facts, entities, edges,
//! bitemporality), the indexes (BM25, temporal, graph, vectors), hybrid
//! recall, and the snapshot/journal machinery. The core owns no I/O, no
//! clock and no threads — timestamps arrive as parameters, bytes leave
//! through the `Storage` trait.
//!
//! Design: `..05`. Implementation lands in stages 2-4; modules
//! appear here in dependency order as those stages complete.

#![no_std]
// The engine holds zero `unsafe`: every byte-reinterpretation lives in
// `plugmem_arena`, behind its single audited `unsafe`. Forbidding it here turns
// "the core is UB-free" into a compile-time guarantee — which is why the MIRI
// audit covers only the arena, not this crate's (necessarily safe) code.
