## Existing basis

Charge/energy–momentum accounting and conditional thresholds are available; core formation/unlocking and rates are unsolved.
<Equation name="mat-recoil-threshold" />

<Equation name="mat-two-photon-threshold" />

<Equation name="mat-reaction-energy" />

## Required work

Use an action admitting stable particles; specify initial/final states and background. Track topology density and all energy fluxes, reconnection and amplitude paths. Use one coupling for forward/reverse channels, angular distributions and polarization.

## Reviewable deliverable

Reproducible time evolution, conservation errors, threshold/recoil checks, normalized rates or cross sections, detector response and the energy budget of any extra longitudinal branch.

## Limits and dependencies

Zero total topology does not guarantee a reaction; one photon cannot form a free pair in a uniform nonexchanging vacuum.
