Struct DsaWindow 

pub struct DsaWindow<const W: usize> { /* private fields */ }

Fixed-capacity DSA window.

W_DSA = window width for accumulation (default 10, paper Stage III). K = persistence threshold (default 4).

Implementations

impl<const W: usize> DsaWindow<W>

pub const fn new(ewma_threshold: f32) -> Self

Create a new DSA window with paper Stage III defaults.

λ = 0.20, unit weights, δ_s = 0.05. ewma_threshold should be set from healthy-window calibration.

pub fn push( &mut self, sign: &SignTuple, grammar: GrammarState, motif_fired: bool, ) -> DsaScore

Push one observation and compute the DSA score.

motif_fired: true if a named (non-Unknown) motif was identified.

pub fn reset(&mut self)

Reset the DSA window (e.g., after post-transition guard expires).

pub fn calibrate_ewma_threshold(&mut self, healthy_norms: &[f32])

Calibrate the EWMA threshold from healthy-window observations.

Sets ewma_threshold = mean_ewma_norm + 3 * std_ewma_norm over healthy window.
