Overview#
Evidence that is deleted too early can collapse a prosecution. Evidence held past its disposal date creates privacy liability. Between those two failure modes sits a complex matrix of jurisdictional rules, legal hold obligations, and storage cost pressures that no manual process reliably handles at scale. The Media Compliance and Retention module automates this lifecycle, applying the correct policy to every piece of evidence from the moment it enters the system through to authorised disposal.
Law enforcement agencies, defence organisations, and intelligence units all face distinct regulatory frameworks. This module supports all of them from a single policy engine, with multi-jurisdiction rule sets that can coexist within the same deployment.

- Tiered storage lifecycle moving evidence between hot, warm, and cold tiers on Cloudflare R2 as access patterns change
- Compliance validation against regulatory requirements and organisational policies
- Scheduled disposal workflows with multi-level approval gates and full audit documentation
- Multi-jurisdiction policy support for organisations operating across regulatory boundaries
- Retention reporting and compliance dashboard for real-time status monitoring
- Policy exception management with documented justification tracking for every deviation
Use Cases#
- Enforcing jurisdiction-specific media retention policies automatically across evidence collections without manual intervention
- Managing legal holds to prevent accidental disposal during active litigation or concurrent investigations
