Boot TX power was left at a conservative 10dBm (Heltec V4's pattern) with
no way to raise it, unlike the T-Deck which boots straight at the chip's
real 22dBm ceiling. On hardware this was silently degrading outbound
range: adverts/DMs sent from the pager were unreliable while inbound
reception was fine, since the far node's own TX power was unaffected.
22dBm is confirmed as this chip's actual sub-GHz HP-PA ceiling via
RadioLib's LR1120::checkOutputPower() (LR1121 inherits it) and matches
trail-mate's own working config for this board.
Also widen the three RX-boosted-gain gates in MyMesh.cpp/DataStore.cpp
that only checked USE_SX1262/USE_SX1268 to include USE_LR1121 --
CustomLR1121Wrapper already implements setRxBoostedGainMode/
getRxBoostedGainMode, so the setting was silently a no-op for this radio.

- History flush runs on the core-0 worker (snapshot + storage-busy gate +
bounded shutdown wait): kills the V4's multi-second ui:hist stalls and
the refuses-to-wake-after-message symptom (SPIFFS GC off the UI thread).
- BLE + Wi-Fi runtime enables share the boot co-init heap guard (50 KB
free + 20 KB block): refuse with a toast + revert the switch instead of
panicking (BLE) or silently not starting while claiming on (Wi-Fi).
- Internal DRAM: static footprint 95,365 -> 64,908 B (30.5 KB freed):
serial_interface -> PSRAM; 23 keyboard layout maps const'd -> flash;
nine rings/tables -> psAlloc PSRAM (UITask/TouchPrefsStore/MyMesh);
unused TinyUSB MSC + DFU-mode class drivers stubbed out of the link
(usb_unused_class_stubs.c) — CDC + runtime-DFU untouched, double-flash
verified over the stubbed stack.
- DataStore prefs writes are crash-safe (write .tmp, swap) with a
self-healing loader (.tmp recovery) and a truthful save result up to
the profile-name toast — fixes the boots-with-default-name-once report.

- DataStore::saveContacts packs byte-identical 152B records into ~5KB chunk
writes (was ~12 tiny FS writes per contact: 2.6-3.0s at ~570 contacts on the
loop thread — the #82 sluggishness); falls back to per-field writes on alloc failure
- Contacts 60s age tick updates the Heard labels in place (was a ~1.3s full
teardown+rebuild); advert-driven rebuilds coalesced to one per 2.5s
- Spectrum: rolling waterfall row + live trace every quarter sweep (~250ms),
8-bin/8ms sweep chunks (~20% faster full sweep); trace Y range now tracks the
live min/max — instant expand, 3dB/sweep contract, 30dB minimum span

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.
