Telemetry Attribute Audit
Audit telemetry attributes against a contract, and against the thing a schema cannot see: cardinality. Reports missing required attributes, undeclared attributes, an attribute appearing as two types across the batch, and an attribute whose distinct values exceed your limit - because in a metrics backend each distinct value is a separate series, and that is how an index or a bill explodes.
