"""Extract line numbers and source hashes for tracked NumPy test functions.

Backs the `core-numpy-sync` skill steps 1-4: it does NOT edit tests - it produces
a machine-readable table (numpy_path, class, method, line, sha256, + metadata)
that feeds `numpy_coverage.csv`. Run on a version bump to detect line drift and
content drift (changed sha256) on transferred tests.

Usage:
    python3 sync_numpy.py <numpy_checkout_root>            # print CSV of tracked surface
    python3 sync_numpy.py <numpy_checkout_root> --hashes    # print path::class::method line sha256 only

The tracked surface (manipulation) is embedded in SURFACE below. To extend
coverage to another rstsr category, add (relpath, class, method) tuples and
their METADATA.
