# Purpose: Fail fast when release versions drift across published ecosystems.
# Key outputs: Compares Cargo, Python, Node, and Node lock/native versions.
# Role: CI/local guardrail for lockstep release policy.
# Invariants: All listed manifests must carry one identical semantic version.
# Notes: Prints a small mismatch report to speed troubleshooting.
