Why this is different
Many observability incidents start as a harmless metric label. This tool treats label design as a release risk: it turns metric rows into a visible cardinality map, flags identifiers that belong in traces or logs instead of metric labels, and exports the exact drop/rewrite policy as YAML, CSV, Markdown and a receipt.
