cf-pipeline-backend 0.0.1

Mixed C++/Python pipeline backend (stub implementation)

cf-pipeline-backend (stub)

Stub Python implementation of the mixed C++/Python pipeline backend described in pipeline_backend/spec/PIPELINE_SPEC.md.

This package exposes:

• __backend_metadata__
• register_py_op, register_cpp_op (bookkeeping only for C++ ops)
• list_ops, describe_ops
• Pipeline (executes Python ops; C++ ops raise NotImplementedError)
• _register_op_capsule (PyCapsule for future C++ plugin registration)

Resources bundled for validation/reference:

• Spec: pipeline_backend/spec/PIPELINE_SPEC.md
• Schemas: pipeline_backend/spec/schemas/{pipeline_backend.schema.json,pipeline_plugin.schema.json}
• Validator helper: pipeline_backend.validator

Example (uses cf_basic_signal, OPC UA virtual pH server):

pip install -e sand_toys/cf_basic_steps/cf_basic_signal
pip install -e sand_toys/cf-pipeline/cf-pipeline-backend
python sand_toys/cf-pipeline/cf-pipeline-backend/examples/run_opcua_fifo_avg_csv.py

Code lives in src/pipeline_backend/. This packaging layer enables tag-driven wheel builds and publishing to PyPI/TestPyPI.
