Module dispatch 

Hybrid Summation Dispatch — Routes reductions to the appropriate accumulator.

Dispatch Rules

Condition	Strategy
ExecMode::Parallel	BinnedAccumulator
@nogc context	BinnedAccumulator
ReproMode::Strict	BinnedAccumulator
Reduction inside LinalgOp	BinnedAccumulator
Serial + ReproMode::On	Kahan Summation
Serial + no vectorization	Kahan Summation
Not forced strict	Kahan Summation

The dispatch path is deterministic and unit-tested.

Structs

ReductionContext

Reduction context passed to the dispatch logic.

Enums

ExecMode

Execution mode for the current context.

ReproMode

Reproducibility mode.

SumStrategy

Which summation strategy to use.

Functions

dispatch_dot_f64

Dot product of two equal-length f64 slices using dispatched summation.

dispatch_sum_f64

Sum f64 values using the strategy appropriate for the given context.

select_strategy

Determine the appropriate summation strategy for the given context.
