Fact 74
On August 16, 2023, during Cyrus's load test, metrics-router triggered a sev3 cardinality canary; Wes checked the deploy path, confirmed there was no router change, traced the spike to an unbounded `experiment_id` label appearing only in load-test traffic, and brought Alex Valdez in within the 45-minute secondary rule for confirmation.

This morning during Cyrus's load test, metrics-router threw a sev3 cardinality canary. Wes took the first pass and made the right call: he checked the deploy path, saw there wasn't a router change, isolated the spike to an unbounded `experiment_id` label coming only from load-test traffic, and pulled me in within the 45-minute secondary rule for confirmation. Cyrus's side stopped the test, the canary cleared, and we avoided an escalation or unnecessary rollback. I want this remembered as a concrete production-judgment signal from him, not an ownership change. Send him a short Slack DM praising that specific call.
