An `export … from './x'` statement emitted one `imports` reference per re-exported name and nothing for the module itself; `export * from` emitted nothing at all. So a barrel made only of `export *` lines had no dependency on what it re-exports (no dependent for `affected`), and sync could not find an `index.ts` that re-exports another barrel: when the inner one was deleted or added, the outer one's importers kept their stale or name-matched edges. A re-export now imports its module the way `import … from` does, in both extractors (TS and the Rust kernel): an import node named by the specifier and a module reference that links the barrel to the file it names. Sync's importer discovery follows such modules to their own importers, carrying the names each passes on (`export *`, a named or renamed re-export, an `export * as ns`), as deep as the resolver chases a re-export; an ES namespace import reads whatever its module passes on. A re-export's import node does not count as a symbol for the "parse produced no symbols" warning, so a barrel with an unparseable line still reports it.
