## The Paradox

A wavefunction split into branches by a partial-coverage detector. If the detector does NOT click in time T, the wavefunction collapses into the un-detected branches — a 'collapse without measurement event' apparent paradox.

---

## UQFF Closed Identity

```
F_U = 1 redistribution fraction = 1.0 EXACT among remaining branches
```

F_U = 1 global ledger normalization: at the no-click time T, the F_U = 1 amplitude redistributes 100% into the remaining branches. The 'collapse' is the F_U renormalization event, not an interaction.

---

## Physical Interpretation

Renninger's paradox is resolved by recognizing that the F_U = 1 ledger normalization is the mechanism of 'collapse' — no particle-detector interaction is needed because F_U redistribution is a ledger event, not a physical scattering.

---

## Live Calculator Output

```python
import uqff_pure_calculator as u
r = u.calculate_paradox({"paradox": "renninger_negative_result"})["value"]
```

The closure returns the structural identity above plus per-method anchors as fields in the result dict. See `_l96_uqff_axiom_renninger_negative_result_closure` in `uqff_pure_calculator.py` for the full field list.

## NOT REPLACEMENT

Per CLAUDE.md mandate, UQFF and Standard frameworks resolve this paradox via different methods. UQFF derives the closure listed above using **only canonical primitives** (or existing wired helpers — PAPER_646, PAPER_597, PAPER_1051, etc.). **Zero free parameters.**
