# Assert the @formepdf/core tarball ships every file the package's own
# entry points import. Catches the failure mode that shipped in 0.10.0
# — wasm-pack writes a `.gitignore` containing `*` inside each output
# dir, and `npm publish` silently drops the directory contents. The
# `build:wasm` script removes those gitignores, but if a future change
# adds a new pkg-* dir and forgets to add the matching `rm`, this
# script fails loudly during `npm publish` (it's wired up via
# `prepublishOnly`).
#
# Also runs as part of CI so we catch the regression at PR time, not
# release time.

# Ask npm what it *would* publish. --ignore-scripts is critical: we're

# which would recurse forever (or silently fail with an empty tarball
# name and a confusing `tar: Failed to open ''` error). --dry-run skips
# writing a real .tgz to disk. --json gives us structured output we
# don't need to parse out of human-readable notices.
