# Pinned reference toolchain for the rev-8.0.0 acceptance oracle.
#
# This image exists for one purpose: regenerating and verifying
# fixtures/strap-beam-8.0.0/. The running application has no OpenSCAD
# dependency at all -- see docs/ENVIRONMENT.md section 8.2. Confining OpenSCAD
# here is why the host's package version cannot drift into the oracle.
#
# Do not add anything to this image. Its value is that it contains nothing else.
