# Smoke tests for the `node_modules`-shape settings that don't expose a

# CLI flag and only surface through `.npmrc` / `pnpm-workspace.yaml`:

#

# * enableModulesDir — persistent equivalent of --lockfile-only

# * virtualStoreDirMaxLength — cap on .aube/<name> directory names

# * virtualStoreOnly — populate .aube/ but skip top-level symlinks

# * modulesCacheMaxAge — sweep orphaned .aube/ entries after install

# * symlink — accept-and-warn; aube's isolated layout

# requires symlinks so symlink=false is a

# no-op but must not fail the install

#

# Each test runs against the offline Verdaccio fixture registry so

# behaviour is deterministic without network access.
