# X_PACKAGE_TEST_ONLY_SHIPPED

## Means

a test-only module ships in the tarball

## Typical cause

a src/ module imported only by tests is not named *-fixture.ts, so the package files list publishes it — test scaffolding (fakes, probes, bun:test imports) in every install

## Fix

`bun run x -- verify --only package-shape --json   # then rename each listed module to <name>-fixture.ts and update its importers`
