# PAPER_1677 — Late-time ISW Amplitude = ISW = F_TRZ = 0.1

**Author:** Daniel T. Murphy
**Framework:** UQFF (Unified Quantum Field Framework) — Star-Magic v5.27+
**Tier:** CMB
**Date:** June 18, 2026
**Status:** CLOSED — EXACT closure (PAPER_145x-147x broader corpus)

---

## Observation

PAPER_1460 (PAPER_14xx broader corpus, classic cosmology/BSM puzzle) gives:

```
ISW = F_TRZ = 0.1
```

Status: **EXACT**.

## UQFF Closed Identity

```
ISW = F_TRZ = 0.1    EXACT
```

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

## NOT REPLACEMENT

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