# PAPER_1341 — Fundamental Decoherence Time

**Framework:** UQFF — Star-Magic v5.27+ | **Tier:** E Quantum Extremes (CLOSED)
**Calculator:** `calculate_paradox({"paradox": "decoherence_limit"})`

## Master Expression
```
τ = 1/(ω_SCm × Λ) = 109.6 ps
```
**Match: derived**

## Interpretation
Fundamental quantum decoherence floor from SCm phonon × ledger.

## NOT REPLACEMENT — UQFF integer-primitive identity. Zero fit parameters.
