Decoded a T-Deck coredump (Task WDT, loopTask stuck in spiffs_gc_clean under
DataStore::saveContacts): a contact save on a churned SPIFFS can trigger a
multi-second garbage-collection pass that starves core 0 and trips the task
watchdog, giving a reboot loop.
- Route contacts/channels to SD when a card is present, even on upgraded
devices whose data is still on SPIFFS (main.cpp mounts SD every boot; if not
fully adopting SD, store.setSecondaryFS(&SD)). DataStore::begin() migrates the
existing /contacts3 + /channels2 to the card once; identity/prefs stay put.
- Move the ref-counted WdtHeavyGuard into a shared header so the core
DataStore::saveContacts shares one count with the UI history/backup saves, and
wrap saveContacts with it (guaranteed fix for card-less devices).

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.
