Issue: Investigate Authentication Service operational risk 02

ID: GH-1002 Date: 2025-07-23 Repository: acme-commerce/authentication-service Service: Authentication Service Owner: Identity Platform Status: open Type: issue

Summary

This issue tracks production-readiness work for the Authentication Service. The concern is related to stale cache entries surviving a blue-green release. The implementation area touches API contracts API-AUTHENTICATION-01, API-AUTHENTICATION-02, service telemetry, and operational runbooks.

Engineering Notes

  • Validate that retries are bounded and idempotency keys are respected.
  • Add structured logs with service, correlation_id, and customer_impact fields.
  • Confirm dashboards show p95 latency, error rate, dependency saturation, and queue depth.
  • Cross-service impact should be reviewed with Checkout Service, Billing Service, Inventory Service, Authentication Service, and Notification Service owners when applicable.

Acceptance Criteria

  1. Contract tests cover expected and malformed payloads.
  2. Runbook references are updated for Authentication Service.
  3. The change can be linked from Jira remediation tickets and incident reviews.
