Independent audit custody

Tenant-aware event ingestion, chain integrity, heartbeat and reconciliation.

Reuse boundary

Custody after arrival does not prove source completeness; freshness bounds integrity assertions.

Supported use cases

• U08: Consumer emits security events and reconciles independently retained evidence
• U09: Maintainer observes posture, prioritizes findings, coordinates work and verifies outcomes
• U10: Operator recovers identity, custody or data with independently held recovery material

Evidence and integration

Assessment: CUST-WP-0081, 2026-10-14. Relations identify interfaces to compose; they do not certify native integration. Existing external evidence levels are retained where present. New entries use conservative C1/R0 until consumer assessment exists.
