> **Historical provenance document — superseded.** This file preserves an earlier project state. It is not the current scientific interpretation. The canonical v0.3 position is that galaxy-specific structural fingerprints are reproducible and organized; sampling and preparation sensitivity describe how the fingerprints are expressed rather than negating their existence.

# UNNS Galaxy Structural Fingerprints v0.1

This is a self-contained research foundation for studying multiscale structural identity in
SPARC galaxy baryonic profiles.

The central object is the chamber-response fingerprint:

`F_G(κ) = [ρ_G(κ), Aκ,G(κ), ν_G(κ)]`.

The folder contains the source corpus, neutral prepared profiles, all chamber ladders, the
two research instruments, direct chamber output exports, consolidated signatures, complete
STRUC-I curves, and a first unsupervised structural curve atlas.

## Current research question

Do complete chamber-response curves define stable, reproducible galaxy fingerprints that
encode baryonic profile organization beyond sampling density and elementary gap geometry?

## Current registered experiment

`GAL-FINGERPRINT-I — Galaxy Structural Identity and Stability Audit` was accepted and
registered on 2026-07-26. Gate A pilot inputs are prepared in 17 chamber batches. No pilot
chamber outputs or scientific verdicts have yet been produced.
