name: Heavy parity (manual)

# Expensive parity tests that need the full 808 MB dump and (for the multithreaded test)
# a lot of RAM. Manual-only — never triggered automatically. The multithreaded test needs
# ~25 GB RAM, which exceeds standard GitHub runners; enable `run_mt` only on a large or
# self-hosted runner.
