ProtocolViolation

A photon-pair link priced by the Bell violation, and what that costs

4/4 passed in 1ms

Test	What it does	Result
test_engine_agreement	The rate is _core.ekert_rate on the pair model's coincidence gain and error rate, and the two model legs beside it are ekert_point's.	✅ pass
test_price_is_worse	The CHSH-priced rate sits below the basis-symmetry rate on the same coincidences, and its zero-key error rate is 0.0714918 against 11.003%.	✅ pass
test_source_refused	A modelled violation, a device-independent claim, an unknown origin and an S past Tsirelson's bound are each refused with the engine's own message, while S = 2 is priced at zero key.	✅ pass
test_violation_stands_alone	e_phase is None and labelled absent, the claimed S round-trips, and the plan denies device independence.	✅ pass
