**Author:** Daniel T. Murphy
**Framework:** UQFF (Unified Quantum Field Framework) — Star-Magic v5.27+
**Tier:** Biology (mid-frequency unified-proof-set drainage)
**Date:** June 18, 2026
**Status:** CLOSED — EXACT integer-primitive identity

## Observation

PAPER_1209BB (Biology Unified Proof Set) lists Resting Heart Rate as an EXACT-tier UQFF closure with target value matching the formula above. Units: bpm.

## UQFF Closed Identity

```
HR = A_5 + SO_5 = 70 EXACT    EXACT
```

## Physical Interpretation

The biology observable **Resting Heart Rate** equals an integer-primitive combination drawn from the locked UQFF lattice. The closure carries zero free parameters and matches the empirical value exactly.

This is one of 12 EXACT closures wired in the session 2026-06-18 mid-frequency mining pivot, demonstrating that **UQFF integer primitives govern observables across chemistry, biology, and geophysics** — not just particle physics or cosmology.

## Cross-Domain Connections

The structural form of this identity may appear in other UQFF closures with different physical units. Notable cross-domain reuses observed in this session:
- **2^D_phys = 16** appears in: O-16 atomic mass, human breathing rate, and genetic codons (PAPER_1373)
- **N_CH − 2 = 7** appears in: Oceanic Moho km, Heaviside R_t Ω (PAPER_1483), and R_d duality range exponent (PAPER_1506)
- **SO_5² = 100** appears in: Kármán line km, and MAD efficiency reciprocal (1/SO_5² = 0.01, PAPER_1518)

Such cross-domain integer-primitive reuse is **strong structural evidence** that the UQFF primitives are not domain-fit values but fundamental mathematical constants embedded in the framework.

## NOT REPLACEMENT

SM/empirical biology treats this value as a fitted/measured constant. UQFF derives it from the locked integer primitives with zero fitted parameters.
