Model note:
This file reproduces the mathematical predictions from sections 4.1-4.3 of the PDF.
It is a numerical model of the author's argument, not an experimental proof.

Parameters
----------
Photons per direct scenario: 40000
Screen bins: 260
Screen half-width: 8.0
Envelope sigma: 3.0
Fringe frequency: 6.0
D5 phase (deg): 0.0
Noise fraction: 0.0700

Summary
-------
Alice finds which-path information: Bob direct interference = NO (contrast 0.000, no direct interference)
Alice does nothing: Bob direct interference = NO (contrast 0.000, no direct interference)
Quantum eraser, Bob direct screen: Bob direct interference = NO (contrast 0.000, no direct interference)
Quantum eraser, coincidence on D1: conditioned pattern only (contrast 0.983)
Quantum eraser, coincidence on D2: conditioned pattern only (contrast 0.983)
D5 path-combination hypothesis: Bob direct interference = YES (contrast 0.983, clear direct interference)
