Scientific Stack Status

NumPy and scientific-stack bring-up status for native extension execution.

This page tracks the public snapshot of scientific-stack compatibility through direct native-extension execution gates.

Base NumPy Gate (2026-02-23 snapshot)

Gate	Status
`numpy_import`	PASS
`numpy_ndarray_sum`	PASS
`numpy_numerictypes_core`	PASS

Direct Scientific-Stack Probe Snapshot (2026-02-23)

Probe	Status
`scipy_import`	PASS
`pandas_import`	FAIL
`pandas_series_sum`	FAIL
`matplotlib_import`	FAIL
`matplotlib_pyplot_smoke`	FAIL

Active P0 Blockers

numpy.ma.core import still overflows stack in current direct bring-up flow.
Pandas direct path currently fails in pandas._libs.tslibs.dtypes with class-attribute lookup mismatch.
Matplotlib direct path still fails in tuple-unpack/call-materialization paths for Cython-heavy modules.
