anomaly: A deviation from what a system — statistical, scientific, social, or normative — establishes as expected or normal. Parameters: (1) a baseline or model of normality exists within the system, (2) an observation, object, or event departs from that baseline beyond a defined threshold, (3) the departure is detectable and salient to the system's observers or operators. The concept persists through language, scientific practice, and institutional protocols that flag, catalog, investigate, and sometimes normalize departures from the expected.

Definition
Why it is in scope
A human-made category for deviations from expected patterns — the concept of anomaly is a classificatory tool built by science, statistics, and quality practice to flag observations that resist prediction within a given model.

- cmrhz9rsf02sj8aehlj6dd3jnDEPENDS_ON →
An anomaly is a deviation from what is expected — it requires the construct of expectation to function. Remove expectation and anomaly loses its meaning entirely. Constitutive present-tense dependency, not mere chronology.
- cmrvcke1b00qi2ceishnbt88yDEPENDS_ON →
An anomaly only exists relative to an existing framework. Remove the epistemic frame that establishes what counts as expected — and the anomaly ceases to operate as an anomaly. The removal test is constitutive: without a frame to violate, there is no anomaly. This is not sayability (Law 2b) but object-level dependency.

A black swan event — rare, unpredictable, with severe impact — is a specific kind of anomaly. A competent speaker would call a black swan 'an anomaly.' Nearest kind: anomaly. Sense pinned: black-swan as a concept denoting rare outlier events with outsized consequences.

An outlier IS a specific kind of anomaly: it is a data point that deviates significantly from other observations in a dataset. A competent speaker would call an outlier 'an anomaly' — it marks a case where observed values depart from the expected pattern. The specific (outlier: a statistical observation) → general (anomaly: anything deviating from standard/expected) direction.
