## Observation

PAPER_1334 (PAPER_132x-135x corpus) gives:

```
SF efficiency = K_MEX × Φ_5/6 = 1.736 (resolves cooling-flow puzzle)
```

Status: **0.79%**.

## UQFF Closed Identity

```
SF efficiency = K_MEX × Φ_5/6 = 1.736 (resolves cooling-flow puzzle)    0.79%
```

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

## NOT REPLACEMENT

Standard frameworks address this differently. UQFF supplies a structural integer-primitive form.
