Slack Thread: Billing Service Follow-up 34

Date: 2026-04-21 Channel: #platform-architecture Service: Billing Service Incident Reference: INC-2025-304 Jira Reference: ACME-3014 GitHub Reference: GH-3018

Jordan Kim: We are reviewing INC-2025-304 for Billing Service. The main concern is whether the remediation in ACME-3014 also covers downstream impact to Checkout Service and Billing Service.

Maya Chen: 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 Billing Service.

Devon Patel: Please make sure GitHub item GH-3018 includes contract tests for API API-BILLING-03 and an update to the runbook.

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

Noah Garcia: Decision: keep ACME-3014 open until staging replay passes and the incident review confirms no unsupported customer-impact claims.
