Do not use it to change a metric definition, target, dashboard, alert, or data source, or to explain a result causally from correlation alone. Not for publishing a number whose source, denominator, window, or as-of point is unknown. ## Inputs and source discipline For each metric, identify the canonical metric definition, formula or counting rule, unit, denominator or population, time window and timezone, source, source date, and as-of date/time. Record freshness expectations, extraction time, revision policy, and known exclusions. If a definition or unit is missing, report unknown rather than substituting a familiar one. Use a source ledger for the current value, comparison values, baseline, and target. Link the query, report, dashboard, or export and record its source date and as-of provenance. Do not mix values from different definitions, units, populations, windows, or timezone cutoffs without marking them non-comparable. ## Method 1. Inventory the metric definition and scope in read-only mode. Confirm that the requested period is closed or label it provisional; record missing data and...
