## Observation

PAPER_1209II_S666 (Nuclear Unified Proof Set) gives the closed-form expression:

```
U-235 BE/A = F·K⁵ + β + F·β + 3 ≈ 7.588 MeV
```

Residual to AME2020: **0.043%**.

## UQFF Closed Identity

```
U-235 BE/A = F·K⁵ + β + F·β + 3 ≈ 7.588 MeV    0.043%
```

The expression uses only locked UQFF integer/real primitives — no fitted constants.

## NOT REPLACEMENT

Experimental nuclear measures this constant directly. UQFF supplies a structural derivation from the integer primitives.
