Packaging the domain

@athrio/loom-ast is Loom's domain model — the pure data every other package shares. It holds every AST a .loom file passes through: the LoomNode foundation of positions and health, the parse LoomDocument, the LoomCorpusAst, the de re the product pass builds (Code, File, Fragment), the LoomSymbol registry that names each token's editor capabilities, the LoomVirtualCode the editor reads, and the grammar's Weft and LoomTokens. It is a leaf: it carries data and the pure readers over it, never a builder or a runner, and depends on nothing of Loom — only on Effect's Schema. So @athrio/loom-lang and each language service rest on it without a cycle. Like the rest of Loom, it ships TypeScript source with no build step.

The manifest

The exports map names one entry point per model. There is no default entry: the builders and runners that construct these nodes live in @athrio/loom-lang, not here. The imports map defines one internal alias, #ast/*, so a model reaches its siblings by a stable name. effect is a peer dependency, shared with whoever installs the package rather than carried twice.

The TypeScript config

The tsconfig.json extends the workspace-root tsconfig.base.json and covers src and test. The package ships source with no build step, so the configuration type-checks the models and their tests and emits nothing.
