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>

| 1 | # Heltec V4 TFT touch firmware — custom partition table. |

| 3 | # 16 MB layout with TWO EQUAL OTA app slots so the touch firmware can |
| 4 | # self-update (HTTP OTA via the meshcomod proxy). The app region (app0+app1) |
| 5 | # is split evenly at 3.875 MB each — the firmware is ~2.4–2.5 MB, leaving |
| 6 | # ~1.3 MB of growth headroom per slot. The tiles + spiffs offsets are UNCHANGED, |
| 7 | # so an OTA (or the one-time USB re-flash that installs this table) keeps the |
| 8 | # map tile cache and all user data (/new_prefs, /contacts3, /channels2, chat |
| 9 | # history) intact. |
| 10 | # - app0 3.875 MB (ota_0) ┐ equal A/B slots; OTA ping-pongs between them |
| 11 | # - app1 3.875 MB (ota_1) ┘ (was 1.5 MB — too small to hold the image) |
| 12 | # - spiffs 3.375 MB for user data |
