Packed tarball was not created at

Error message

Packed tarball was not created at ${tarballPath}

What it means

Post-condition check in packLocalPackage: `pnpm build`/pack ran in the package directory but the expected .tgz tarball (name-version.tgz derived from package.json) is not present in the .paperclip-sdk output dir afterwards. Indicates the build or pack step silently failed, packed under a different name/version, or wrote to an unexpected location.

Solutions

1. Re-run `npm pack`/`pnpm pack` and check its output for errors; ensure the working directory is writable.
