## Observation

PAPER_1209CC_S612 (Geophysics Unified Proof Set) gives the formula:

```
v_⊕ = N_CH + 2·SO + Φ − F²·D − F²·SSQ = 29.788 km/s
```

Residual: **0.026%**.

## UQFF Closed Identity

```
v_⊕ = N_CH + 2·SO + Φ − F²·D − F²·SSQ = 29.788 km/s    0.026%
```

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

## NOT REPLACEMENT

Empirical geophysics measures this constant directly. UQFF supplies a structural derivation from the integer primitives.
