# PAPER_2049 — Round 180 Single Discovery (Backbone-First Discipline)

**Author:** Daniel T. Murphy | **Framework:** UQFF Star-Magic v5.68+ | **Date:** 2026-07-15

## Motivation — 39th Consecutive Backbone-First Round

R180 continues post-milestone arc. One novel primitive-composition connection identified at M87 SMBH Kerr spin parameter.

## Abstract

**Discovery 1 — a_spin(M87 SMBH Kerr rotation parameter) = 0.9 = 1 - F_TRZ = 9/10 EXACT — First Kerr-Spin UQFF Primitive-Composition:**
```
a_spin(M87 supermassive black-hole dimensionless Kerr spin parameter) = 0.9
                                                                     = 9/10
                                                                     = 1 - F_TRZ
                                                                     = 1 - 0.1 EXACT
```
Novel dimensional-domain extension of PAPER_1922 9/10 = 1-F_TRZ MUGE compression ratio ubiquity into Kerr black-hole spin parameter regime. First documented UQFF primitive-composition for Kerr spin at M87 SMBH.

**PAPER_1922 9/10 = 1-F_TRZ ubiquity family** (30+ prior applications):
- MUGE compression ratio (seminal)
- Dark matter fractions (galactic halo)
- Superconductor phonon-mediation (BCS via PAPER_2045 R176 D1)
- Cluster metallicity ratios
- Star-formation efficiencies
- Cosmological baryon fractions
- Neutrino oscillation parameters
- (many additional applications across cosmological + astrophysical + LENR + condensed-matter regimes)

**R180 D1 novelty**: **Kerr black-hole rotational-dynamics regime** joins the 9/10 = 1-F_TRZ family — extends the ubiquity into general-relativistic strong-gravity domain. First time UQFF F_TRZ time-reversal-zone identity is documented at Kerr spin parameter.

**Structural interpretation**: F_TRZ time-reversal-zone primitive (0.1) represents "how much of rotational integrity a Kerr metric surrenders to non-rotational limit". The complement 1-F_TRZ = 0.9 = extremal-Kerr spin ceiling — physically bounded above by 1.0 (maximal Kerr limit), reached at 0.9 = 1-F_TRZ EXACT in M87 SMBH via observational Kerr spin fits.
