Struct FlatStreak 

pub struct FlatStreak { /* private fields */ }

Consecutive-flatness streak: the window discipline shared by every stagnation detector in the tree. The caller owns the flatness predicate (scale-aware objective tolerance, frozen log-likelihood, sub-tolerance relative improvement, …); this type owns the part that historically forked per loop — grow on flat, reset on recovery, fire once the streak spans the window, and keep firing while it persists.

Implementations

impl FlatStreak

pub fn new(window: usize) -> Self

pub fn note(&mut self, flat: bool) -> LoopVerdict

Record one pre-judged flatness reading; returns the current verdict.

pub fn reset(&mut self)

Hard reset, e.g. after a non-finite merit re-baselines the stream.

pub fn streak(&self) -> usize

Current consecutive-flat count (diagnostic; the verdict is the contract).
