Anomaly Operational Dictionary

Anomaly-driven Operational Dictionary

An operational dictionary stores thresholds and norms that anomaly detection and stewards use to interpret signals.

Why this is needed

Without norms, every spike looks like an incident—or nothing does.
Controlling and ops need shared thresholds.
Fits EntiHub anomaly scheduling and steward triage.

Proposed entities in EntiHub

Governance settings

Setting	Recommended value	Why
`approvalRequired`	`true`	Threshold changes affect alerting behavior.
`historyEnabled`	`true`	Compare norms across periods.
`allowSameAuthorApproval`	`false`	Maker/checker separation for sensitive changes.
`deletedRetentionDays`	`90` (or higher)	Soft-delete retention for auditability.
