First board lands. wadamesh builds the LVGL touch firmware as its own project, consuming the MeshCore core via lib_deps @ git tag (ALLFATHER-BV/MeshCore #v1.16.0-wada.0) — no vendored core in this repo. Output is byte-identical to the in-tree meshcomod build (delta = embedded build-path strings only). Contents: companion_radio app (MyMesh/main/DataStore), ui-touch LVGL UI, variants/heltec_v4 board glue, boards/heltec_v4.json, lv_conf, the bundled ed25519 lib, AsyncElegantOTA, partition table, and a flattened platformio.ini for env heltec_v4_tft_companion_radio_usb_tcp_touch. MeshCore-derived files (app glue) remain MIT; ui-touch is GPL — see NOTICE. Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com> Signed-off-by: Kaj Schittecat <kaj@schittecat.com>
