The P4's internal FFat 'locfd' has a broken FAT metadata layer: open/ read/write work but f_stat/exists()/size() return garbage - and WHICH garbage shifts with the build. At -Og the exists()-gated identity and NodePrefs loads worked by luck; the -Os switch flipped the lie and the device booted with a fresh identity and default name, and profile changes never survived a reboot (the loads failed, not the saves). Chat history was unaffected because it already lives on SD_MMC. - DataStore::useSdMmcStorage(): full-store adoption of the card (/meshcomod root, identity store included), mirroring the T-Deck's useSdStorage(). The old card-root contacts3/channels2/adv_blobs from the secondary-FS era are renamed under /meshcomod. - Tanmatsu boot: one-time rescue of identity + prefs off FFat by OPEN and READ probing (never exists()/size() on that FS), then adopt the card. FFat remains the no-card fallback only. - DataStore::loadPrefs() probes candidates by opening and reading a byte instead of exists() - truthful on the P4, identical elsewhere.

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.
