cf-pipeline-sdk 0.2.1

Cogniflow pipeline SDK (cf_siggen + headers)

cf_pipeline_sdk

cf_pipeline_sdk packages the native SDK assets needed by Cogniflow step packages:

• the Python module cogniflow_pipeline_sdk
• the python -m cogniflow_pipeline_sdk.siggen entry path
• packaged C/C++ headers for downstream builds
• the cf_siggen native binary copied into the installed package

Published distribution name:

pip install cf-pipeline-sdk

Scope

The published distribution name is cf-pipeline-sdk. The Python import package remains cogniflow_pipeline_sdk.

Downstream native step packages consume the SDK through:

• import cogniflow_pipeline_sdk
• cogniflow_pipeline_sdk.cf_sdk_include_path()
• cogniflow_pipeline_sdk.cf_siggen_path()
• python -m cogniflow_pipeline_sdk.siggen

Validation Spec Output

cogniflow_pipeline_sdk.validation.generate_validation_spec(...) keeps the existing normalized port fields unchanged:

• id
• key
• types
• name
• multi for input ports

When a step manifest port declares cf:valueContract, the generated port entry now adds a value_contract object with additive metadata:

• shape_kind
• element_types
• table_schema.columns[] with name, type, and nullable when a table schema is declared

If a legacy cf:portType/cf:parameterType fallback conflicts with cf:valueContract/cf:elementType, validation spec generation fails with a ValueError that names the affected step and member identifier. This keeps legacy migration paths explicit while exposing the shared shape-aware contract metadata.

Native build prerequisites

The SDK is built with scikit-build-core and CMake.

For Windows publish/preflight runs, use:

• CPython 3.14
• CMake on PATH
• a working Windows C++ toolchain compatible with that CMake installation

The CI publish workflow targets windows-latest. If your local machine exposes multiple CMake/compiler combinations, keep the selected CMake and compiler toolchain consistent for the whole build.

Publishing

cf_pipeline_sdk is published with the dedicated Windows workflow:

• Workflow: .github/workflows/cf_pipeline_sdk_windows_publish.yml
• Package directory: sandcastle/cf_pipeline/cf_pipeline_sdk
• PyPI tag: cf-pipeline-sdk-v<version>
