Slack Thread: Authentication Service Follow-up 22

Date: 2026-02-28 Channel: #release-checkout Service: Authentication Service Incident Reference: INC-2025-102 Jira Reference: ACME-1002 GitHub Reference: GH-1006

Devon Patel: We are reviewing INC-2025-102 for Authentication Service. The main concern is whether the remediation in ACME-1002 also covers downstream impact to Checkout Service and Billing Service.

Priya Shah: I checked traces for Authentication Service, Inventory Service, and Notification Service. The correlation IDs line up with the incident timeline, but the highest error rate stays inside Authentication Service.

Noah Garcia: Please make sure GitHub item GH-1006 includes contract tests for API API-AUTHENTICATION-03 and an update to the runbook.

Elena Rossi: Agreed. I will add release readiness notes, dashboard screenshots, and a rollback checkpoint before this goes to canary.

Sam Rivera: Decision: keep ACME-1002 open until staging replay passes and the incident review confirms no unsupported customer-impact claims.
