template<typename FF >

template<typename ContainerOverSubrelations , typename AllEntities , typename Parameters >

void bb::TranslatorShiftableFirstCoeffZeroShortRelationImpl< FF >::accumulate ( ContainerOverSubrelations &  accumulators, const AllEntities &  in, const Parameters &  , const FF &  scaling_factor  )

static

Anchors the first coefficient of the shiftable ordered_range_constraints polynomials to zero.

Anchors ordered_range_constraints_i[0] = 0 for each of the 5 sorted range-check wires (short-monomial form).

Short-monomial counterpart of TranslatorShiftableFirstCoeffZeroRelation: pins ordered_range_constraints_i[0] = 0, making explicit the lower-endpoint invariant that the Gemini/Shplemini shift mechanic already enforces. See the long relation for the full rationale.

Parameters

evals	transformed to evals + C(in(X)...)*scaling_factor
in	an std::array containing the fully extended Univariate edges.
parameters	contains beta, gamma, and public_input_delta, ....
scaling_factor	optional term to scale the evaluation before adding to evals.

static bool bb::TranslatorShiftableFirstCoeffZeroShortRelationImpl< FF_ >::skip ( const AllEntities &  in )

inlinestatic

Returns true if the contribution from all subrelations for the provided inputs is identically zero.

Every subrelation carries a lagrange_first factor, so on any edge where lagrange_first is identically zero all five contributions are the zero polynomial. lagrange_first is nonzero only on the first row, so this skips the degree-2 products on essentially every edge. This tests the actual edge values (not a selector), so it is sound in every sumcheck round.
