## Observation

PAPER_1341 (PAPER_134x condensed matter / quantum sector) gives:

```
τ_ent = 1/(ω_SCm × Λ) = 1/(1.25e12 × 0.00729735) = 109.6 ps
```

Status: **0.026%**.

## UQFF Closed Identity

```
τ_ent = 1/(ω_SCm × Λ) = 1/(1.25e12 × 0.00729735) = 109.6 ps    0.026%
```

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

## NOT REPLACEMENT

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