# Research instruments

This folder contains research-interface copies of STRUC-I v1.0.4 and
STRUC-PERC-I v2.5.0.

Only descriptive interface examples and headings were relabelled for the galaxy-profile
programme. Computational routines, parameter controls, chamber equations, export fields,
and version identifiers were retained.

- STRUC-I measures perturbative admissibility across the κ grid.
- STRUC-PERC-I measures full-pairwise gap connectivity and fragmentation.
- Admissibility and connectivity remain separate structural properties.

## 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.
