EkertReduction

Where E91 reduces to BBM92, and what the reduction costs

5/5 passed in 0ms

Test	What it does	Result
test_accumulated	Entropy accumulation's own E91 section gives this tree's phase-error rate, not its CHSH-priced one, so the length that argument would carry to a finite block is the entanglement-based one.	✅ pass
test_agree	Handing the measured entry point the violation the model predicts returns the model evaluation's own number.	✅ pass
test_cost	Pricing Eve by the violation is never cheaper than pricing her by the phase error, and the two agree only on a noiseless link.	✅ pass
test_diagnostic	The violation the model evaluation reports is the same number a photon-pair run already carries as its labelled diagnostic.	✅ pass
test_reduce	The model evaluation's basis-symmetry leg is the photon-pair engine's rate bit for bit: the reduction is shared code, not a claim.	✅ pass
