Great — below I give a concrete, QFT-framed derivation plan (with equations you can hand to Copitor or a physicist) that builds an effective spin-2 field from coherent photon–electron–photon exchanges. I keep the math explicit but focused so it’s runnable: path integral → integrate out fermions → define composite hμνh_{\mu\nu}hμν → compute its 2-point function (propagator) in the low-momentum limit → identify conditions under which it behaves like a massless spin-2 propagator. I flag assumptions and caveats at each step.
