Architecture

Zimanyar is a TypeScript monorepo. Each package may import only those in lower layers, and make check-imports holds it to that.

layer	packages	does
0	config	shared settings and design tokens
1	data	loads the compiled lexicons
2	core	the linguistic engine, a port of zimankit
3	rules	the document model and every checking rule
4	checker, i18n	runs rules in a worker with a cache; the interface strings
5	ui, content	the components; the lessons
6	editor	underlines and cards on any text field
6	practice	drills, spaced repetition and the mistake history
apps	web	this website

core uses no DOM, browser or Node-only APIs, so the same engine runs in a worker, in Node and in the desktop app.

Parity fixtures exported from zimankit decide what the engine should do. The tables in the lessons are computed by the engine at build time, and a test holds each one to zimankit’s output.
