Struct Episode 

pub struct Episode {
    pub index: usize,
    pub residual_norm_sq: f64,
    pub drift: f64,
    pub grammar: &'static str,
    pub decision: &'static str,
}

A structured episode produced by the DSFB observer layer.

Advisory only. No upstream state is modified.

Fields

index: usize

Sample index within the input slice.

residual_norm_sq: f64

Squared residual norm (|x - nominal|²), avoiding sqrt for kernel compatibility.

drift: f64

Rolling drift estimate (mean first-difference of absolute residuals over last 5 samples).

grammar: &'static str

Grammar state: "Admissible", "Boundary", or "Violation".

decision: &'static str

Advisory decision: "Silent", "Review", or "Escalate".

Trait Implementations

impl Clone for Episode

fn clone(&self) -> Episode

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for Episode

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl PartialEq for Episode

fn eq(&self, other: &Episode) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
