AGPL-3.0 Components — Justification
object storage, logs layer, and Dashboards use AGPL-3.0. AKKO tolerates this because:
1. These are existing infrastructure components, not new additions
2. AKKO does not modify their source code — uses official images as-is
3. AGPL requires source distribution only if the software is modified and distributed
4. All three are industry-standard with no viable permissive-licensed alternative at equivalent quality
