Slack Thread: Inventory Service Follow-up 28

Date: 2026-01-05 Channel: #platform-architecture Service: Inventory Service Incident Reference: INC-2026-408 Jira Reference: ACME-4008 GitHub Reference: GH-4012

Maya Chen: We are reviewing INC-2026-408 for Inventory Service. The main concern is whether the remediation in ACME-4008 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 Inventory Service.

Priya Shah: Please make sure GitHub item GH-4012 includes contract tests for API API-INVENTORY-01 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-4008 open until staging replay passes and the incident review confirms no unsupported customer-impact claims.
