Use this skill whenever a parity claim, frozen-snapshot claim, or native-C++ claim is about to be made.
.venv/bin/python scripts/frozen_source_manifest.py --verifycpp/, scan the native tree with:
.venv/bin/python scripts/check_native_cpp.py --allcpp/ as native-debt, not as fully
converted C++ coverage.cpp/,
do not count it as native-converted coverage.Use a deterministic browser workflow only when direct fetch or extraction is insufficient for a public-web task.
Run the smallest correct verification lane and report it precisely.
Keep public-web research compliant, bounded, and efficient through rule checks, caching, and backoff instead of evasive scraping.
Optimize a parity-proven ome-zarr native C++ surface for measurable speedups by improving data layout, copies, cache behavior, and boundary design without changing behavior.
Benchmark converted code against the frozen upstream implementation before making performance claims.
Port one upstream ome-zarr-py surface to standalone native C++ without touching the frozen snapshot.
