# PR Data Meta Model - validation stack
#
# PINNED ON PURPOSE. The venv on GrosseBertha runs Python 3.9
# (/usr/local/bin/python3.9, the only stable interpreter on DSM 7.4).
#
# Newer pyshacl releases advertise 3.9 support but use PEP 604 syntax
# (str | X) in runtime annotations, which needs 3.10+. pip installs them
# without complaint and the import then dies with:
#     TypeError: unsupported operand type(s) for |: 'type' and 'ABCMeta'
#
# 0.26.0 is the version verified working on this interpreter (2026-07-26).
# Do not unpin without rebuilding the venv and re-running the validator.
#
#   /usr/local/bin/python3.9 -m venv venv
#   . venv/bin/activate && pip install -r requirements.txt
