Immutable Parity Proof
Use this skill whenever a parity claim, frozen-snapshot claim, or native-C++
claim is about to be made.
Required checks
- Verify the frozen snapshot manifest with:
.venv/bin/python scripts/frozen_source_manifest.py --verify
- Run differential tests against the frozen snapshot on identical inputs.
- Prefer content-addressed comparisons:
- serialized output trees for store-backed paths
- patched outbound call payloads for external side effects
- stable JSON-like outcome snapshots for deterministic object behavior
- If the change touches
cpp/, scan the native tree with:
.venv/bin/python scripts/check_native_cpp.py --all
- Treat any embedded-Python execution in
cpp/ as native-debt, not as fully
converted C++ coverage.
Reporting rule
- State the manifest verification result.
- State the exact parity suites that ran.
- If a surface is still wrapper-heavy or depends on embedded Python in
cpp/,
do not count it as native-converted coverage.
