 * compare against `done`/`archived`, or it stalls forever on a renamed board. That is what the
 * compound-engineering reconciler now does — but this shim is what `@fusion/core` resolves to inside
 * the bundled build, so an import it does not re-export is a hard esbuild failure ("No matching
 * export"), not a runtime fallback. The plugin built fine in the workspace and broke only in the CLI
 * bundle.
 *
 * Source paths, not the package barrel, for the reason above: esbuild follows core's source here and
 * the CLI must not take a private @fusion/core dependency.
