+This file provides guidance to Claude Code (claude.ai/code) when working with code in this repository.
+
+## Project Overview
+
+Tactility is an operating system for the ESP32 microcontroller family. It runs on 40+ supported devices (CYD boards, LilyGO, M5Stack, Elecrow, etc.) and includes a desktop simulator. Built with C++23, ESP-IDF, LVGL, and FreeRTOS.
+
+## Build Commands
+
+### Simulator (Linux/macOS, no ESP-IDF needed)
+
+```bash
+cmake -B buildsim -G Ninja
+ninja -C buildsim              # build firmware + tests
+./buildsim/Firmware/Tactility   # run simulator
+```
+
+### ESP32 firmware
+
+```bash
+python device.py <device-id>   # generate sdkconfig for device (e.g. lilygo-tdeck)
+python device.py <device-id> --dev  # dev mode: force 4MB partition table
+idf.py build                   # build firmware
+idf.py flash monitor            # flash and monitor
+```
+
+Device IDs are the folder names under `Devices/` (e.g. `lilygo-tdeck`, `m5stack-cores3`, `cyd-2432s028r`).
+
+### Tests
+
+Tests use Doctest and run on simulator (POSIX) target only:
+
+```bash
+cmake -B buildsim -G Ninja
+ninja -C buildsim build-tests
+cd buildsim && ctest            # run all tests
+./buildsim/Tests/TactilityCore/TactilityCoreTests    # run a single test suite
+./buildsim/Tests/TactilityKernel/TactilityKernelTests
+./buildsim/Tests/Tactility/TactilityTests
+./buildsim/Tests/TactilityFreeRtos/TactilityFreeRtosTests
+```
+
+## Architecture
+
+### Layer Stack (bottom to top)
+
+- **TactilityKernel** — C API kernel: device/driver/module lifecycle, concurrency primitives (thread, mutex, timer, dispatcher), filesystem, logging. Header convention: `<tactility/*.h>` (lowercase snake_case).
+- **TactilityCore** — Former kernel subproject. Deprecated, replaced by TactilityKernel. Contains C++ utilities: Bundle (key-value data), string helpers, file I/O, crypto. Header convention: `<Tactility/*.h>` (UpperCamelCase).
+- **TactilityFreeRtos** — Thin C++ wrappers around FreeRTOS primitives.
+- **Tactility** — Main OS layer: app framework, service framework, HAL (deprecated, replaced by TactilityKernel), LVGL integration, networking and services (Wi-Fi, BLE, NTP, ESP-NOW), settings, i18n.
+- **TactilityC** — C bindings (`tt_*.h`) for TactilityCore and Tactility subprojects, used by side-loaded ELF apps on ESP32. Deprecated, replaced by TactilityKernel.
+- **Firmware** — Entry point (`app_main`).
+
+### Device/Driver/Module System (kernel layer, C API)
+
+The kernel uses a Linux-inspired device model:
+
+- **Module** (`struct Module`): loadable unit that registers drivers and hardware. Lifecycle: `module_construct` → `module_add` → `module_start`. Each device board and platform is a module.
+- **Driver** (`struct Driver`): binds to devices via `compatible` strings (like devicetree). Has `start_device`/`stop_device` callbacks and an `api` pointer for type-specific operations.
+- **Device** (`struct Device`): represents hardware. Lifecycle: `device_construct` → `device_add` → `device_start`. Has a parent-child tree, driver binding, and locking.
+- **DeviceType** (`struct DeviceType`): enables discovering devices by category (e.g. `DISPLAY_TYPE`, `TOUCH_TYPE`, `UART_CONTROLLER_TYPE`).
+
+Devices are defined via **devicetree** `.dts` files in each `Devices/<id>/` folder. A custom devicetree compiler (`Buildscripts/DevicetreeCompiler/compile.py`) generates C code from these files. Each device folder also has a `devicetree.yaml` specifying dependencies and the `.dts` file.
+
+### App Framework
+
+Apps implement `tt::app::App` (or just provide callbacks). Each app has an `AppManifest` with `appId`, `appName`, `appCategory`, and a factory function `createApp`. Apps are registered at startup in `Tactility.cpp`. External apps can be loaded from SD card via `manifest.properties` files, or side-loaded as ELF binaries on ESP32.
+
+### Service Framework
+
+Services implement `tt::service::Service` with a `ServiceManifest`. Services are long-running background processes (GUI, Wi-Fi, loader, statusbar, GPS, etc.).
+
+### HAL Layer
+
+#### Deprecated HAL
+
+Located in Tactility folder.
+
+`tt::hal::Configuration` is declared per-device board (in `Devices/<id>/Source/Configuration.cpp`). It provides `initBoot` for early hardware setup and `createDevices` to instantiate HAL device wrappers (display, touch, power, keyboard, etc.).
+
+#### Current HAL
+
+Located in TactilityKernel. Based on Linux driver subsystems.
+
+#### Driver
+
+A driver generally consists of:
+- Registration of driver in parent module (optional)
+- YAML bindings in the `bindings/` folder
+- An `#include` that is used in the `.dts` file. The include is in `[projectname]/bindings/[drivername].h`
+- The driver implementation: a `.cpp` and `.h` file. The implementation is C++, but the header exposes pure C functions.
+
+Drivers can be stored in:
+- TactilityKernel
+- A subproject in Platforms/ folder
+- A subproject in Devices/ folder
+- A subproject in Drivers/ folder. This is a kernel module. Naming is lower case and postfixed with `-module`
+
+#### Kernel Modules
+
+Projects that are kernel modules:
+
+1. Declare a `struct Module`
+2. Contain a `devicetree.yaml` file that declares a list of dependencies (for parsing the devicetree) and specifies the bindings folder that contains the drivers' YAML definitions. For example:
+```yaml
+dependencies:
+  - TactilityKernel
+bindings: bindings
+```
+
+### Platform Abstraction
+
+- `Platforms/platform-esp32/` — ESP-IDF specific implementations
+- `Platforms/platform-posix/` — POSIX simulator implementations (SDL for display)
+
+### Build System
+
+The `tactility_add_module()` CMake macro (in `Buildscripts/module.cmake`) wraps ESP-IDF's `idf_component_register` on ESP32 and standard `add_library` on POSIX, allowing the same source to build for both targets.
+
+`device.py` reads `Devices/<id>/device.properties` and generates the `sdkconfig` file with all necessary ESP-IDF config (target chip, flash size, SPIRAM, LVGL fonts, Bluetooth, USB, etc.).
+
+### LVGL
+
+User interfaces should scale well for everything between very large (e.g. 1280x720) and small (e.g. 135x240) displays. Vertical and horizontal layouts are supported.
+
+## Coding Style
+
+Two conventions coexist; which one to use depends on the project layer:
+
+- **C code** (TactilityKernel, drivers): `lower_snake_case` for files, functions, variables. `UpperCamelCase` for types. Files in `source/`, `include/`, `private/` directories.
+- **C++ code** (TactilityCore, Tactility, apps, services): `UpperCamelCase` for files and types. `lowerCamelCase` for functions. Files in `Source/`, `Include/`, `Private/` directories.
+
+Formatting is enforced by `.clang-format` (LLVM-based, 4-space indent, no column limit).
+Never throw exceptions — use return types for error handling. Use `enum class` over plain `enum`.
+Don't do null checks: caller is responsible for passing valid data.
+Pointers are expected to be non-null unless documented otherwise.
+
+## Key Conventions
+
+- `#ifdef ESP_PLATFORM` guards ESP32-specific code; the simulator uses POSIX equivalents.
+- The `Drivers/` directory contains hardware drivers (display controllers, touch controllers, PMICs, etc.) — each is its own CMake component.
+- `Modules/` contains cross-cutting modules: `hal-device-module` (device lifecycle) and `lvgl-module` (LVGL task management).
+- `Data/system/` and `Data/data/` are flashed as FAT filesystem images on ESP32.
+- Translations are in `Translations/` as CSV files, generated via `generate.py`.

+# GameBoy side-loaded ELF support notes
+
+This branch records the firmware-side changes used to make the Tactility GameBoy emulator prototype load past the generic `missing symbol` failure on an ESP32-S3 ES3C28P board.
+
+## Problem
+
+Side-loaded `.app` packages are relocated by the firmware ELF loader. The app can build successfully against the local SDK but still fail at runtime if the board firmware does not export every dynamic symbol used by the app.
+
+For the GameBoy prototype, USB serial logs showed the emulator app was being found and started, but firmware without the needed LVGL exports showed missing-symbol failures for the canvas path.
+
+## Firmware changes in this branch
+
+`TactilityC/Source/tt_init.cpp` now includes LVGL and exports the core LVGL canvas/display functions the GameBoy app needs:
+
+- `lv_canvas_create`
+- `lv_canvas_set_buffer`
+- `lv_obj_invalidate`
+- `lv_display_get_horizontal_resolution`
+- `lv_display_get_vertical_resolution`
+
+These are exported through the existing `main_symbols[]` table with `ESP_ELFSYM_EXPORT(...)`, making them visible to side-loaded ESP32-S3 app ELFs.
+
+The branch also removes the `AlwaysRun` devicetree delete target from `Firmware/CMakeLists.txt`. During iterative firmware builds this target deleted `Generated/devicetree.c` while compile rules still depended on it, causing intermittent build failures. The devicetree generation rule now depends directly on the source YAML.
+
+## Verification performed
+
+On the iMac build host:
+
+```bash
+cd ~/Projects/gitea/tactility
+. ~/esp/esp-idf/export.sh
+python3 device.py es3c28p
+idf.py build
+idf.py -p /dev/ttyACM0 flash
+```
+
+Build result:
+
+```text
+Tactility.bin binary size 0x2b82b0 bytes
+Smallest app partition is 0x400000 bytes
+0x147d50 bytes (32%) free
+```
+
+Flash target:
+
+```text
+ESP32-S3 ES3C28P
+USB serial: /dev/ttyACM0
+MAC: 14:c1:9f:d0:5c:5c
+```
+
+Runtime serial showed the GameBoy core loop running and reporting approximately 49-50 FPS:
+
+```text
+GAMEBOY_FPS 50
+GAMEBOY_FPS 49
+GAMEBOY_FPS 49
+```
+
+## Current caveat
+
+The app loop/FPS is running, but the photographed device showed the GameBoy framebuffer was not visibly rendering yet. That remaining issue is in the app/UI canvas presentation path, not the firmware missing-symbol issue addressed by this branch.
+
+## Related app work
+
+The app-side prototype lives in the separate Gitea repo:
+
+```text
+https://git.reynafamily.com/adolforeyna/tactility_apps.git
+```
+
+The app branch changes include restoring the LVGL canvas path, using `/data/roms/gb/default.gb` for the flashed data-image test, and printing `GAMEBOY_FPS` markers over USB serial.

 ## Higher Priority

- Make a root device type so it can be discovered more easily.
- When device.py selects a new device, it should automatically delete the build dirs (build/, cmake-*/) when it detects that the platform has changed.
+- Require either SD card present or at least 8MB of flash. This way we can increase firmware size, ensure performance, and have a single location for storing data.
+- Consider storing data on SD card in `/tactility` folder (for usage with Launcher)
 - Add font design tokens such as "regular", "title" and "smaller". Perhaps via the LVGL kernel module.
 - Add kernel listening mechanism so that the root device init can be notified when a device becomes available: 
  Callback for device/start stop with filtering on device type:

 - Make WiFi setup app that starts an access point and hosts a webpage to set up the device.
  This will be useful for devices without a screen, a small screen or a non-touch screen.
 - Unify the way displays are dimmed. Some implementations turn off the display when it's fully dimmed. Make this a separate functionality.
- Try out ILI9342 https://github.com/jbrilha/esp_lcd_ili9342
- All drivers (e.g. display, touch, etc.) should call stop() in their destructor, or at least assert that they should not be running.
 - Bug: Turn on WiFi (when testing it wasn't connected/connecting - just active). Open chat. Observe crash.
 - Bug: Crash handling app cannot be exited with an EncoderDevice. (current work-around is to manually reset the device)
- I2C app should show error when I2C port is disabled when the scan button was manually pressed

 ## Lower Priority

- The boot button on some devices can be used as GPIO_NUM_0 at runtime
