H-118 is standalone. The historical h0xx_*.py files retained in this package are Python modules reachable through the frozen simulator import chain used by H-118. They are not old batch launchers or result artifacts.

Primary H-118 imports:
- h049 numerical field instrument
- h086 external exact GR light-bending ruler (opened only after FV seal)
- h089 frozen continuous photon transit
- h104 current-cell path helpers
- h108 process-RSS instrumentation
- h110 reduced spectral solver
- h113 symmetry-clean scaled-source field construction
- h116 frozen three-axis Shapiro clock coupling
- h117 frozen static redshift clock mechanism
