Data Packet Policy
No regression of DMR data support is permitted.
FreeDMR should forward supported DMR data packets according to conference/subscription and mesh rules. The FreeDMR core should not become a general GPS/SMS application processor.
GPS, SMS, and similar application processing should be implemented by systems connected via FBP or another mesh/access-adjacent interface. DATA-GATEWAY is understood as an earlier expression of this model.
Existing SUB_MAP / last-known-location behaviour is intentional: data addressed to a DMR ID can be routed toward the last known HBP/client location.
Narrow exceptions may exist for SMS-based dial-a-TG control or DMR SMS alerts to the sysop.
Data/control classification must be separate from group-vs-unit addressing. A group-addressed data packet is not automatically a voice stream.
The packet layer may inspect data packets for admission, routing, loop/source-quench safety, reporting, and metadata preservation. Application-level GPS/SMS semantics should live outside the core unless a specific control-plane feature requires it.
