1//! The verified no-alloc indicator subset.
2//!
3//! Each indicator here reproduces the exact floating-point recurrence of its
4//! `wickra-core` counterpart — same operation order, same reseed cadence, same
5//! division points — so its output is byte-for-byte identical, verified by the
6//! `parity` tests. The window length is a const generic `N`; there is no runtime
7//! buffer and no allocation.
