hedron-conformance
Language-neutral Hedron conformance-test kit and capability runner.
Ships versioned machine-readable fixtures, golden render/diagnostic artifacts, normalization rules, and a capability-level runner CLI so experimental Java/Node runtimes and optional native accelerators can prove parity with the Python reference — without matching incidental CPython formatting.
Also available as the flagship extra hedron[conformance].
Package maturity: Beta · Train: 0.50.x (published v0.50.3) · pin >=0.50.1,<0.51

pip install "hedron-conformance>=0.50.1,<0.51"
# or
