# Verify that every ADR-0092..0099 lane produces its pinned SHA-256
# report. A failing job means a lane's deterministic output changed
# without an explicit ADR-tracked pin update via:
#
#   python scripts/verify_lane_shas.py --update
#
# Single source of truth for the pinned values is scripts/verify_lane_shas.py.
