+**Single source of truth**: `CMakeLists.txt` line 3 `project(JNetApplet VERSION x.y.z)`.

+- `package/metadata.json.in` uses `@PROJECT_VERSION@` placeholder, substituted at
+  configure time -> installed `metadata.json` always matches.
+- `build-deb.sh` extracts the version directly from `CMakeLists.txt` via grep.
+- **To bump the version**: edit only the `project(... VERSION ...)` line in
+  `CMakeLists.txt`. All downstream consumers (install, deb) pick it up automatically.
