1- HYBRID CORE 5.1.0-0922

MAIN MANAGEMENT CONTROL PLANE
- Board hierarchy, connections, staff/role pulls, Board membership and permissions.
- Receiver configuration, historical data pulls, schema migrations and backups.
- One visible Core entrance.

DEPLOYMENT BOUNDARY
- Install this module on the Main Management CRM.
- Connected remote CRMs still require their local Hybrid Receiver adapter.
- Deactivating a remote Receiver stops live pull/push communication.
- Existing data tables are preserved during an in-place upgrade.

STAGING
- Upgrade Core before Hybrid Boards.
- Do not delete existing module folders or database tables during the first upgrade test.
