1- HYBRID CORE 5.1.0 (BUILD 0921-06)

RECEIVER RECOVERY FIX
- An existing Board with no Receiver can now select a Receiver in Edit.
- The new relationship is locked when saved.
- A Board that already has a Receiver remains read-only and protected.
- Existing Board ID, hierarchy, services, territory and records remain unchanged.
- The update is recorded by the existing Board audit process.

PRESERVED
- Standalone Board Network Manager and controlled move workflow.
- Board Type Welcome panel.
- Receiver, staff, permission and pull management.

QA BOUNDARY
Static source and archive integrity are checked outside the target Perfex runtime.
Receiver selection, save, audit and subsequent data display require staging verification.
