`VERIFY_ENGINE.py` compares 15 normalized core function bodies against the canonical `reference/struc_i_v1_0_4_galaxy_profiles.html` source. Python does not reimplement the authoritative Monte Carlo measurement.

## v0.3 project interpretation

This document contributes to the galaxy structural-fingerprint programme. Numerical, technical, protocol, or provenance content above is preserved. The canonical interpretation is that the fingerprints are reproducible, organized, and galaxy-specific; sampling, coverage, and baryonic-preparation dependence describe the transformation of fingerprint expression and do not erase the structural finding.
