# GAL-FINGERPRINT-I Pilot Preparation Record

**Prepared:** 2026-07-26  
**Protocol:** accepted GAL-FINGERPRINT-I v0.1  
**State:** chamber inputs prepared; no pilot chamber result has been generated or inferred

## Completed engineering work

- accepted protocol inserted as the permanent registered record;
- one bounded generation/consolidation pipeline added;
- full registered deletion generator verified at 782 realizations;
- all 121 primary R1 profiles reconstructed from direct chamber exports;
- reconstructed R1 curves matched the frozen 4,840-row consolidated table;
- 100 real pilot ladders generated from the frozen prepared corpus;
- 17 six-slot-compatible chamber batches created;
- input hashes and batch assignments recorded;
- package validation Boolean-serialization defect corrected;
- curve-atlas builder expanded to reconstruct all five tables, three figures, and the foundation report.

## 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.
