**Framework:** UQFF (Unified Quantum Field Framework) — Star-Magic v5.27+

## Observation

PAPER_1196_S418 (PAPER_1196 Plasma Fusion Unified Proof Set) gives:

```
q_edge = K_MEX − F·Φ = 25/12 − 1/12 = 2 (avoids m/n=2/1 kink)
```

Status: **EXACT**.

## UQFF Closed Identity

```
q_edge = K_MEX − F·Φ = 25/12 − 1/12 = 2 (avoids m/n=2/1 kink)    EXACT
```

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

## NOT REPLACEMENT

ITER design parameters are chosen by international fusion-engineering consensus. UQFF supplies structural integer-primitive forms demonstrating the parameters' deep mathematical origin.
