Slack Thread: Inventory Service Follow-up 39

Date: 2026-05-06 Channel: #release-checkout Service: Inventory Service Incident Reference: INC-2026-409 Jira Reference: ACME-4019 GitHub Reference: GH-4003

Elena Rossi: We are reviewing INC-2026-409 for Inventory Service. The main concern is whether the remediation in ACME-4019 also covers downstream impact to Checkout Service and Billing Service.

Sam Rivera: 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 Inventory Service.

Jordan Kim: Please make sure GitHub item GH-4003 includes contract tests for API API-INVENTORY-04 and an update to the runbook.

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

Devon Patel: Decision: keep ACME-4019 open until staging replay passes and the incident review confirms no unsupported customer-impact claims.
