# GAL-FINGERPRINT-I — Gate A Engineering Pilot Execution Plan

**Protocol:** `analysis/gal_fingerprint_i/protocol/GAL_FINGERPRINT_I_PROTOCOL_v0_1.md`  
**Status:** inputs prepared; chamber execution pending  
**Pilot panel:** frozen 12 galaxies  
**Confirmatory use:** none — all pilot results are excluded from registered inference

## Purpose

The pilot tests the execution path, not the scientific verdict. It verifies deterministic ladder naming, manifest mapping, six-slot batching, JSON/CSV pairing, κ alignment, n=8 and n=10 acceptance, branch-generation rules, deduplication, consolidation, and source-rank calculations.

Total pilot chamber realizations                   100
```

The 100 realizations are arranged into 17 chamber batches. Batches 001–016 contain six CSV files. Batch 017 contains four CSV files.

The pilot uses one representative deletion per panel galaxy rather than the full confirmatory deletion set. The pipeline self-test separately verifies the complete registered deletion generator and confirms the frozen full-sample count of 782 realizations.

For M/L testing, each panel galaxy receives one alternating disk variant. The four bulge-bearing panel galaxies receive one alternating bulge variant. This tests both accepted M/L pathways without converting the pilot into the full registered experiment.

For the stochastic-generation branches, the pilot uses only the first registered seed:

random stratified thinning   91001
gap-order null               92001
uniform-range null           93001
```

## Input package

```text
inputs/ladders/struc_i/gal_fingerprint_i/pilot/
├── GAL_FINGERPRINT_I_PILOT_BATCHES.zip
├── pilot_batch_manifest.csv
└── chamber_batches/
    ├── PILOT_BATCH_001/
    ├── ...
    └── PILOT_BATCH_017/
```

The master ZIP contains the batch folders and manifests. The individual batch ZIP files are stored beside their corresponding batch folders.

## Export destination

Place the direct STRUC-I JSON and CSV exports under:

```text
outputs/exports/struc_i/gal_fingerprint_i/pilot/
```

These are direct chamber output exports. They are not raw observational data.

## Completion condition

Gate A chamber execution is complete only when:

- all 100 manifest ladder names occur exactly once after exact-file deduplication;
- every realization has one JSON-backed and one CSV-backed profile;
- every profile contains 40 valid κ points;
- instrument version, κ range, κ steps, and Monte Carlo count match the protocol;
- the consolidated pilot contains exactly 4,000 curve rows;
- the registered primary and sensitivity distances can be calculated against the frozen R1 gallery.

## 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.
