+## Project status
+
+This repository is currently at a **pre-v1 no-hardware milestone**.
+
+What is true today:
+- the repo builds
+- automated tests pass
+- dry-run, offline generation, and simulated transmit paths run without hardware
+- core architecture for config/control/output is in place
+
+What is not yet true:
+- real SDR hardware transmission is not integrated
+- this should not yet be presented as a final v1.0 release
+
+## Recommended tag
+
