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: 0.64.x (published as v0.64.0 on PyPI) · application pin >=0.64.0,<0.65; repository checkouts use uv sync
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>=0.64.0,<0.65"
# or
uv add "hedron-conformance>=0.64.0,<0.65"
# via flagship:
pip install "hedron[conformance]>=0.64.0,<0.65"
Checkout tip v0.64.0 uses uv sync; applications install >=0.64.0,<0.65 from PyPI.
Requires Python 3.11–3.14.
