## Present interpretation

The project has established galaxy-specific structural fingerprints with exceptional unchanged-ladder reproducibility.

The fingerprint atlas contains:

- physical galaxy organization;
- observation geometry;
- chamber-state regime;
- galaxy-specific multiscale response morphology.

Gate C shows how the fingerprint moves when the representation changes. The next instrument will model and normalize that movement.
