Fact 83
The first cut of Cardinality Guardrails is deliberately limited to label limits, alert-source semantics, and label-change preflight.

In the Q4 planning discussion, Hema asked me to turn the September mirror/replay cardinality wobble into a named controls effort instead of leaving it as a planning note, and I agreed to own it as Cardinality Guardrails. Cyrus will help connect the pipeline failure modes to data-platform cost, but the first cut is deliberately narrow: label limits, alert-source semantics, and label-change preflight. I want to leave the meeting with a kickoff note that prevents this from becoming a general telemetry rewrite or a legacy-aggregator retirement story. Can you turn the planning notes into a crisp kickoff note with owner split, first-cut scope, non-goals, and immediate next steps?
