nakui-core

Engine of nakui: tokens, schema, DAG, cascade, WAL.

Token = value unit (Decimal, String, Date, Bool, Reference, ...). Schema declares fields + relations + view_hint. Dag keeps dependencies. Every mutation goes through WAL (write-ahead log) before touching memory — recoverable after crash. Topological-order cascade; atomic invariants validated pre-commit.

API

use nakui_core::{Engine, Schema, Token};

let mut eng = Engine::new(Schema::load("...")?);
eng.set("A1", Token::dec("123.45")?)?;
eng.commit()?;  // WAL sync + cascade

Deps

• serde, rust_decimal, petgraph, blake3
