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: 0.54.x (in-tree tip v0.54.0) · pin >=0.54.0,<0.55 (PyPI still >=0.52.0,<0.53 while deferred)
Phase 0.52 authority contract: RFC-0079 / #522.
Phase 0.53 Application DX Stage 1 lives in the flagship package — see Application DX API.
Install
pip install "hedron-conformance>=0.52.0,<0.53"
# or
uv add "hedron-conformance>=0.52.0,<0.53"
# via flagship:
pip install "hedron[conformance]>=0.52.0,<0.53"
Checkout tip v0.54.0 uses >=0.54.0,<0.55 until the Git tag / PyPI upload lands.
Requires Python 3.11–3.14.
