# FreeDMR 2 Architecture Notes
|
|
|
|
This directory contains the distilled FreeDMR 2 design notes. The older notes in `docs/codex-notes.md`, `docs/freedmr-2-architecture-decisions.md`, and the test/API docs remain source material and engineering history.

|
|
|
FreeDMR 2 is not a blind rewrite of packet behaviour. The protected asset is the FreeDMR operating model: DMR packet semantics, dial-a-TG, TG/DMR-ID-centric routing, loop control, source quench, mesh behaviour, RF-side tolerance, data forwarding, and practical amateur-radio interoperability.

Architecture Decision Records live in `adr/`. They record proposed FreeDMR 2 decisions separately from implementation work.
|
|
|
|
Current FreeDMR 1.x remains live until FreeDMR 2 is tested. Compatibility adapters are allowed where useful, but old HBLink object layout, dashboard socket assumptions, and legacy `BRIDGES` structure should not define the FreeDMR 2 core.

FreeDMR 2 keeps Twisted initially but is designed for eventual worker-process scaling. Non-packet-path workers such as reporting/global export move first; packet-plane routing workers are a later stage after state ownership and message-boundary tests are proven.
