Slack Thread: Billing Service Follow-up 15

Date: 2025-09-24 Channel: #release-checkout Service: Billing Service Incident Reference: INC-2025-305 Jira Reference: ACME-3015 GitHub Reference: GH-3019

Devon Patel: We are reviewing INC-2025-305 for Billing Service. The main concern is whether the remediation in ACME-3015 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 Billing Service.

Noah Garcia: Please make sure GitHub item GH-3019 includes contract tests for API API-BILLING-04 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-3015 open until staging replay passes and the incident review confirms no unsupported customer-impact claims.
