1//! NEDB v2 — Content-addressed DAG storage engine.
2//!
3//! Architecture:
4//!
5//! objects/ — content-addressed, encrypted, BLAKE2b-verified nodes (immutable)
6//! indexes/ — id index (file-per-doc) + sorted indexes (BTreeMap, in-memory)
7//! graph/ — typed DAG edges (filesystem entries)
8//! MANIFEST — BLAKE2b Merkle root of all collection HEADs
9//!
10//! Properties:
11//! - Uncorruptable: atomic writes (tmp→rename), hash verification on read
12//! - Parallel: no global lock on writes; each doc has its own index file
13//! - Instant cold start: no AOF replay; rebuild sorted indexes in parallel
14//! - Self-healing: migrate.rs handles v1→v2 on first startup
15//! - Tamper-evident: BLAKE2b chain from MANIFEST → collection heads → nodes
