# UNNS Gravity Bridge v0.1 — Chamber Signature Consolidation

## Completion

- Primary SPARC galaxies joined: **121 / 121**
- STRUC-I summary records selected: **121**
- STRUC-I profile rows consolidated: **4840**
- STRUC-PERC-I primary records joined: **121**
- Audit status: **121 PASS, 0 FAIL**

## STRUC-I

- Regime: **Geometric Persistence — 121**
- Stable Structure: **110**
- Weak Persistence: **11**

Weak Persistence galaxies:

- ESO563-G021
- F574-1
- IC2574
- NGC1003
- NGC2998
- NGC3198
- NGC3972
- NGC5985
- NGC7793
- UGC02487
- UGC11820

## STRUC-PERC-I

- HARD_FRAGMENTATION: **103**
- FULL_PERCOLATION: **17**
- TAIL_FRAGMENTATION: **1**
- GIANT_COMPONENT_PERCOLATION: **0**

Connectivity scope derived from the exported `kappa_connect` values:

- NOT_REACHED: **104**
- MAIN_GRID: **0**
- ADAPTIVE_EXTENSION: **17**

All 17 native FULL_PERCOLATION records have `kappa_connect > 1` and are therefore
labelled **ADAPTIVE_EXTENSION** in the derived scope column. The native verdict itself is preserved.

The sole TAIL_FRAGMENTATION primary galaxy is:

- UGC02953

## Cross-chamber count

| STRUC-I state | STRUC-PERC-I verdict | Count |
|---|---|---:|
| Stable Structure | HARD_FRAGMENTATION | 94 |
| Stable Structure | FULL_PERCOLATION | 15 |
| Stable Structure | TAIL_FRAGMENTATION | 1 |
| Weak Persistence | HARD_FRAGMENTATION | 9 |
| Weak Persistence | FULL_PERCOLATION | 2 |

## Duplicate handling

Exact duplicate STRUC-I download records were collapsed for **4** primary galaxies:

- NGC1090
- NGC2403
- NGC2683
- NGC2841

The canonical record selection rule was: latest timestamp, with natural filename order used
only to resolve timestamp ties. The duplicate records above were identical downloads, not
treated as independent Monte Carlo repeats.

## Fields not present in the supplied STRUC-PERC-I batch export

The following planned fields were not available and were not fabricated:

- chain span;
- edge density;
- outlier fraction.

## Interpretive boundary

This is a chamber-signature data product. It does **not** yet establish a relation to gravity.
The next stage must join these whole-galaxy signatures to the radial SPARC measurements and
compare grouped out-of-sample models against ordinary baryonic profile controls.

## v0.3 project interpretation

This document belongs to the external transfer experiment. Numerical, technical, protocol, or provenance content above is preserved. The transfer result tests one static global architecture: it does not negate the galaxy-specific structural information carried by the curves. Complete curves retain identity, and ρ is the leading channel for local or regime-conditioned follow-up.
