# A bill of materials for what actually ships, and a signature over it.
#
# The interesting claim about this package is not its dependency tree: it is
# that the tree is empty. Nothing here imports anything outside the standard
# library at runtime. That is worth being able to check rather than assert,
# so the SBOM is generated from a fresh environment holding nothing but this
# package, and the step after it fails if anything else turns up. pip is
# expected, because creating an environment puts it there; a second name
# beside it would mean this package grew a dependency.

# signature binds is this workflow in this repository, which is the only
# thing worth binding: it says the file came from the build rather than from
# somebody's laptop.
