pisti87's T-Deck rebooted every time he logged into a repeater, but only in
Hungarian. The login clock-skew warning does:
snprintf(msg, n, TR("Device clock differs from \"%s\" by %lu min%s"),
name, minutes, suffix);
and the Hungarian row reordered the conversions to "%lu ... %s ... %s". Varargs
are positional, so snprintf read the name POINTER as an unsigned long and then
took the minute count -- the integer 3 -- as a char* and dereferenced address 3.
Instant panic, every login, Hungarian only. English fit the declared order, so
it never showed there.
Fixing the four bad Hungarian rows is not sufficient: TR() returns a format
string and translations come from .lang files that users download or hand-write,
so any file can crash any device. TR() now compares the ordered conversion
signatures of key and translation and falls back to the English key on a
mismatch -- the key IS the call site's format string, so it is always correct.
The scan runs only for keys containing '%', which is a small minority.
Also fixed the four rows (three were Hungarian-only crashes or dropped values),
bumped hu to v11, and taught audit-lang.py to fail the build on a mismatch so a
future translation PR cannot reintroduce this. Unit-checked that the audit
detects the original bad row and accepts the repaired one.

A real touchscreen UI for your mesh radio. · open source · GPL-3.0
Touch-UI MeshCore companion-radio firmware for the LilyGo T-Deck / T-Deck Plus and Heltec V4 + TFT (ESP32-S3).
An LVGL touch UI — map, chat, contacts, channels, settings — split out of
meshcomod. The app depends on a
MeshCore fork via PlatformIO lib_deps.

Architecture
This repo holds only the app: the companion_radio glue, the ui-touch
LVGL UI, the two boards' glue/variants, and platformio.ini. The MeshCore
core is not vendored here — it's pulled as a library via lib_deps from the
ALLFATHER-BV/meshcomod monorepo
(the same repo as the non-touch firmware), pinned by a lean source-only core-*
git tag. The touch-app files this repo owns (TouchPrefsStore, WifiRuntimeStore,
the transports, …) are dropped from the lib via -DMC_VENDORED_TOUCH_APP so they
aren't compiled twice. The build is byte-identical to the original in-tree
meshcomod firmware.
Build
PlatformIO pulls the core fork and all libraries automatically:
pio run -e heltec_v4_tft_companion_radio_usb_tcp_touch # Heltec V4 TFT
pio run -e LilyGo_TDeck_companion_radio_touch # LilyGo T-Deck
# or just `pio run` to build both
Flash with the NVS-preserving 4-component chain (bootloader / partitions /
boot_app0 / firmware at 0x0 / 0x8000 / 0xe000 / 0x10000) so saved Wi-Fi
credentials survive — not a merged image, which 0xFF-pads and wipes NVS.

License
GPL-3.0-or-later — see LICENSE. wadamesh is copyleft: anyone who distributes a build or a fork must also make their source available under the GPL. This keeps the UI open and concentrates community effort instead of fragmenting it into closed forks.
wadamesh incorporates and depends on MeshCore (MIT, © Scott Powell / rippleradios.com) and other third-party components — see NOTICE for the full list and their licenses. MeshCore-derived files keep their MIT notices; the combined work is distributed under the GPL (MIT is GPL-compatible). The MeshCore fork that wadamesh builds against stays MIT on purpose, so its Wi-Fi/BLE hooks remain upstreamable to MeshCore.
