[Code scan] Pass matrix.basis into the interface workflow heredoc #7571

This issue is a result of a Codex global repository scan.

The manual interface GitHub Actions workflow defines basis in the matrix, but the Python heredoc in the “Create mock data & patch script” step references basis without defining it or passing it through the environment. The workflow can therefore fail with NameError: name 'basis' is not defined before mock data is generated.

Matrix entries:

Environment and Python heredoc:

Undefined reference:

Relevant code:

env:
  SCRIPT: ${{ matrix.script }}
  PREFIX: ${{ matrix.prefix }}
run: |
  python3 << 'PYEOF'
  import os, re, textwrap

  script = os.environ["SCRIPT"]
  prefix = os.environ["PREFIX"]
  ...
  if basis == "pw":

Suggested fix:

Add BASIS: ${{ matrix.basis }} to the step environment and read basis = os.environ["BASIS"] inside the heredoc.
