@jr need context on the 5xx spike after deploy. Pull the likely cause and give me a rollback call if this is the auth change.

On it. Pulling deploy diff, recent error groups, and queue callback failures for the last 30 min.

Found it. Error rate jumped 7x immediately after commit 9f4e2c in auth middleware. 87% of failures are invalid_signature from webhook verification.

Roll it back and drop the status update text for #eng-incidents.

Done. Rollback is live. Error rate is trending down. Draft posted to #eng-incidents: “Rolled back auth middleware regression from 9f4e2c; webhook 5xx recovering.”
