cf-basic-signal 0.1.0

Cogniflow basic signal step package (FIFO/average) with optional C++ acceleration.

cf.basic.signal StepPackage

Basic signal-processing steps packaged for Cogniflow.

Steps

• cf:FifoWindowBufferStep (windowed buffer)
• cf:AverageStep (arithmetic / geometric / harmonic mean)

Files

• cf-step-package.yaml - manifest
• steps.ttl - ontology fragment for the steps
• cf_basic_signal/steps.py - implementations (with optional C++ backend)
• examples/golden_fifo_avg.json - minimal golden pipeline (InlineSource -> FIFO -> Average)

Quick check

1. Install package:

from core.step_package_manager import StepPackageManager
m = StepPackageManager("path/to/gui_sandbox.duckdb")
m.install_from_manifest("cf_basic_signal/cf-step-package.yaml")

2. Load server and verify:

from core.algorithm_server import AlgorithmServer
s = AlgorithmServer("path/to/gui_sandbox.duckdb")
assert s.step_registry.has_step("cf:FifoWindowBufferStep")
assert s.step_registry.has_step("cf:AverageStep")

3. Run the golden pipeline JSON via your pipeline runner. Expected window: [4,5,6], mean 5.0, small SE.

Wheel builds & publishing

• Wheels are built with cibuildwheel for CPython 3.9-3.12 across Windows, Linux, and macOS in .github/workflows/cibuildwheel.yml (config lives in pyproject.toml).
• The workflow runs the existing cf_basic_steps test job first, then builds wheels for both cf-basic-signal and cf-basic-io, and uploads them as artifacts.
• PyPI publishing happens only on tagged pushes matching v* (excluding tags that contain -test), uploading both wheels and an sdist via the trusted publisher action (pypa/gh-action-pypi-publish).
• TestPyPI publishing happens on tags like v*-test using the same trusted publisher action (no secrets needed; uses OIDC).
