Interface: ExtremumFold ​

Defined in: indicators/src/kernels.ts:361

The windowed extremum as a fold — highest/lowest's monotonic deque, with the array's absolute index replaced by a step counter so the state can be snapshotted and resumed. Amortized O(1) per step; a snapshot copies the ring and the deque (O(period)).
