VCBench v1.0.0 #1

	name: baselines-drift

	# Re-runs the reference-value drift detectors that lock the on-disk
	# baseline + per-dimension JSON / CSV artefacts to §I.4 capability matrix
	# numbers. If anyone re-runs the pipeline and the resulting JSONs come out
	# different from the manuscript, this workflow fails the PR.
	#
	# Once the preprint is posted these reference values are part of the
	# historical record and must not silently change. Any intentional update
	# requires a CHANGELOG.md entry plus an explicit edit to
	# tests/reference_values.json in the same commit.
