Crate anomalyx_detect 

ax-detect — the detector engine

A Detector is a contract: given a normalized RecordSet, it either runs and emits Findings, or it declares honest Absence (e.g. “no numeric columns”). It never fabricates a clean result for data it couldn’t assess. The Registry runs a set of detectors deterministically and collects everything into one Report, which the CLI turns into a tq1 envelope.

All math routes through ax_core::det, so every detector inherits order-independent, reproducible reductions.

Modules

cadence

Cadence anomaly detector (metronomic regularity).

calibrate

Unified confidence calibration.

coll

Collective anomaly detector (CUSUM level shift).

config

Detector configuration and the config-version fingerprint.

ctx

Contextual anomaly detector (seasonal subseries).

dist

Distributional drift detectors — they compare a column in the current corpus against the same column in a baseline. With no baseline they report honest Absence: drift is undefined without something to drift from.

fdr

Multiplicity control for per-cell significance tests — Benjamini–Hochberg false-discovery-rate (FDR) control.

linalg

Minimal, deterministic linear algebra for the multivariate detector.

mv

Multivariate outlier detector (Mahalanobis distance).

point

Statistical point-anomaly detector.

robustz

Robust modified z-score primitives, shared by the point and contextual detectors so the (mutation-pinned) scale selection and confidence mapping live in exactly one place.

structural

Structural anomaly detector.

Structs

Registry

An ordered set of detectors. Order is fixed at registration, so output is deterministic; the envelope re-sorts findings, but absence order follows registration for a stable contract.

Report

What a detector emits into the shared report. Detectors push findings and, when they cannot meaningfully run, mark themselves absent with a reason.

ScanContext

The corpus (or pair of corpora) under assessment.

Traits

Detector

A single anomaly-detection contract.
