library_json.ts

Builds a LibraryJson from a package.json and analyzed modules.

Curates package_json to the publish-safe PkgJson subset via pkg_json_from_package_json, so a full package.json (the common case from gro's loader or a JSON import) is accepted and stripped, while an already-curated PkgJson passes through unchanged.

keys overrides the curated field set, and must match the keys passed to the build-time strip (fuz_ui's vite_plugin_pkg_json): the re-strip here drops any field not in keys, so a wider build-time list with the default here would silently discard the extras. Pass the same shared list to both.

A library, as two clean projections of its inputs: pkg_json (the curated, publish-safe subset of package.json) and source_json (the svelte-docinfo analysis). Both are raw data — every derived value (repo url, npm url, published, the module/declaration hierarchy, …) is computed by the consumer (fuz_ui's Library class), not stored here, so nothing can go stale.

A library's analyzed source: the module metadata produced by svelte-docinfo.

modules is typed as svelte-docinfo's wire shape (ModuleJsonInput), the input side where defaulted arrays and booleans may be absent. Its Vite plugin (virtual:svelte-docinfo) and CLI emit exactly this compacted shape; gro's loader instead hands back the parsed output-side superset (defaults materialized), which is structurally assignable and can be re-compacted to the wire shape with compactReplacer. Either way consumers must treat defaulted fields as optional. svelte-docinfo is an optional peer dependency — install it to type this field, otherwise the reference degrades to any.
