> **Historical provenance document — superseded.** This file preserves an earlier project state.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.

# Changelog

## v0.1

- Created a separate galaxy structural-fingerprint research corpus.
- Consolidated source data, ladders, instruments, direct chamber output exports, signatures, and full curves.
- Added a neutral baryonic-profile table.
- Added a structural curve descriptor table and unsupervised PCA atlas.
- Registered the identity-and-stability audit as the next research gate.

## GAL-FINGERPRINT-I protocol registration — 2026-07-26

- Accepted and registered `GAL-FINGERPRINT-I` protocol v0.1.
- Preserved `repeat_01` as the genuine R1 pass and canonical direct export location.
- Added one tested generation, export-audit, consolidation, and retrieval pipeline.
- Prepared the 100-realization Gate A pilot in 17 six-slot chamber batches.
- Corrected package-validation Boolean serialization.
- Expanded the curve-atlas builder to reconstruct every retained atlas artifact.
- Did not create or fabricate any pilot chamber output.
