The Audit Trail service maintains a unified, searchable record of actions taken across Plumery and integrated third-party systems. It ingests access logs from Plumery’s ingress gateway for actions performed within Plumery, and accepts events published directly by non-Plumery services for actions that happen outside Plumery’s boundary. Both are stored side by side, tagged by origin (internal vs external), and made queryable through the audit-trail-api
