Slack Thread: Notification Service Follow-up 07

Date: 2026-03-25 Channel: #platform-architecture Service: Notification Service Incident Reference: INC-2026-507 Jira Reference: ACME-5007 GitHub Reference: GH-5011

Maya Chen: We are reviewing INC-2026-507 for Notification Service. The main concern is whether the remediation in ACME-5007 also covers downstream impact to Checkout Service and Billing Service.

Devon Patel: 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.

Priya Shah: Please make sure GitHub item GH-5011 includes contract tests for API API-NOTIFICATION-04 and an update to the runbook.

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

Elena Rossi: Decision: keep ACME-5007 open until staging replay passes and the incident review confirms no unsupported customer-impact claims.
