# 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
|
|
|
|
- [SCOPE.md](../../SCOPE.md)
|
|
- [docs/stream-completeness.md](../../docs/stream-completeness.md)
|
|
|
|
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.
