Slack Thread: Notification Service Follow-up 05

Date: 2026-03-03 Channel: #team-service-review Service: Notification Service Incident Reference: INC-2026-505 Jira Reference: ACME-5005 GitHub Reference: GH-5009

Sam Rivera: We are reviewing INC-2026-505 for Notification Service. The main concern is whether the remediation in ACME-5005 also covers downstream impact to Checkout Service and Billing Service.

Jordan Kim: 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 Notification Service.

Maya Chen: Please make sure GitHub item GH-5009 includes contract tests for API API-NOTIFICATION-02 and an update to the runbook.

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

Priya Shah: Decision: keep ACME-5005 open until staging replay passes and the incident review confirms no unsupported customer-impact claims.
