One scored point.

Fields

index: usize

Position in the input series.

value: f64

The observed value.

saliency: f64

Spectral residual saliency of the point (≥ 0).

score: f64

Saliency relative to the preceding judgement window (≥ 0).

expected: f64

Low-frequency reconstruction of the series with anomalies removed.

lower: f64

expected − margin.

upper: f64

expected + margin.

is_anomaly: bool

score > threshold and the value clears the z-score gate.

near_edge: bool

The point lies within κ = 5 places of an end of its batch, where the transform’s own boundary handling moves the saliency most.

The method extends the series by κ points before transforming, and the transform is circular, so that appended block sits next to the last points and the first ones. Measured on a noisy sawtooth of 200 points, replacing the predicted extension with the series’ real continuation moves the saliency of the five points at either end about eight times as much as it moves the middle – and the two ends by the same amount, which is why this is not a tail-only flag.

It is a property of the position, not a verdict: a real anomaly near an end is still reported as one. What it says is that a lone flag here is the one worth a second look, and an anomaly count is worth reporting with and without these.
