+
+Behavioral guidelines to reduce common LLM coding mistakes. Merge with project-specific instructions as needed.
+
+**Tradeoff:** These guidelines bias toward caution over speed. For trivial tasks, use judgment.
+
+## 1. Think Before Coding
+
+**Don't assume. Don't hide confusion. Surface tradeoffs.**
+
+Before implementing:
+- State your assumptions explicitly. If uncertain, ask.
+- If multiple interpretations exist, present them - don't pick silently.
+- If a simpler approach exists, say so. Push back when warranted.
+- If something is unclear, stop. Name what's confusing. Ask.
+
+## 2. Simplicity First
+
+**Minimum code that solves the problem. Nothing speculative.**
+
+- No features beyond what was asked.
+- No abstractions for single-use code.
+- No "flexibility" or "configurability" that wasn't requested.
+- No error handling for impossible scenarios.
+- If you write 200 lines and it could be 50, rewrite it.
+
+Ask yourself: "Would a senior engineer say this is overcomplicated?" If yes, simplify.
+
+## 3. Surgical Changes
+
+**Touch only what you must. Clean up only your own mess.**
+
+When editing existing code:
+- Don't "improve" adjacent code, comments, or formatting.
+- Don't refactor things that aren't broken.
+- Match existing style, even if you'd do it differently.
+- If you notice unrelated dead code, mention it - don't delete it.
+
+When your changes create orphans:
+- Remove imports/variables/functions that YOUR changes made unused.
+- Don't remove pre-existing dead code unless asked.
+
+The test: Every changed line should trace directly to the user's request.
+
+## 4. Goal-Driven Execution
+
+**Define success criteria. Loop until verified.**
+
+Transform tasks into verifiable goals:
+- "Add validation" → "Write tests for invalid inputs, then make them pass"
+- "Fix the bug" → "Write a test that reproduces it, then make it pass"
+- "Refactor X" → "Ensure tests pass before and after"
+
+For multi-step tasks, state a brief plan:
+```
+1. [Step] → verify: [check]
+2. [Step] → verify: [check]
+3. [Step] → verify: [check]
+```
+
+Strong success criteria let you loop independently. Weak criteria ("make it work") require constant clarification.
+
+---
+
+**These guidelines are working if:** fewer unnecessary changes in diffs, fewer rewrites due to overcomplication, and clarifying questions come before implementation rather than after mistakes.

+# Architecture: App Framework
+
+Apps are event-driven, C API (`app-module`, `<app/*.h>`), not a C++ class. Each app has an `AppManifest` (`id`, `name`, `category`, `location`, `flags`) and a `main(app_instance_id, argc, argv)` entry point (`AppMainFn`), modelled on a C program's `main()`. Every app instance gets its own dedicated task for its whole lifetime, and blocks in that task until it returns.
+
+Lifecycle and inter-app communication go through `app_manager_*()` (`app/manager.h`) and `app_event_*()` (`app/event.h`):
+- `app_manager_start()`/`app_manager_start_with_parameters()` launch a plain instance; `app_manager_start_for_result()` launches a modal child that reports back to a parent instance.
+- An app subscribes with `app_event_subscribe()`/`app_event_await()` and reacts to `APP_EVENT_CLOSE` (terminate now) and `APP_EVENT_RESULT` (a child it started reported back).
+- An app closes itself by calling `app_manager_finish()` right before returning from `main()`; another instance is closed via `app_manager_stop()`.
+
+Apps are registered at startup via `app_manager_add()`. External apps can be loaded from SD card via `manifest.properties` files, or side-loaded as ELF binaries on ESP32 (see `app/loader.h`'s `AppLoaderApi`).
+
+Apps can be loaded from:
+
+- memory (`APP_LOCATION_MEMORY`)
+- a path pointing to an install folder where an `.app` file was installed (`APP_LOCATION_PATH`)
+- a path pointing to an `.elf` file (`APP_LOCATION_PATH`)
+
+An app can build an optional UI via the LVGL window-manager module (see `lvgl.md`).

+The kernel uses a Linux-inspired device model:
+
+- **Module** (`struct Module`): loadable unit that registers drivers, hardware and symbols. 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.

+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.
+

+# Building
+
+## Git
+
+The repository uses git submodules. Make sure to use `--recurse-submodules` on relevant git commands.
+
+## Simulator (Linux/macOS, no ESP-IDF needed)
+
+> [!IMPORTANT]
+> The simulator does **NOT** build or run on native Windows (Win32/PowerShell/cmd). This is
+> a hard platform limitation, not a missing tool or PATH issue — do not attempt `cmake -B
+> buildsim` on Windows, it will not work. WSL is a separate, Linux environment and is fine.
+
+```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`).
+
+### Windows: activating the ESP-IDF environment
+
+On native Windows, `idf.py` is not on PATH by default — it must be activated per-shell first.
+The install script places a PowerShell profile activator per IDF version at
+`%IDF_TOOLS_PATH%\Microsoft.v<version>.PowerShell_profile.ps1` (path controlled by the
+`IDF_TOOLS_PATH` environment variable, set to wherever ESP-IDF's tools were installed, e.g.
+`C:\Espressif\tools`). Source it before running any `idf.py` command:
+
+```powershell
+. "$env:IDF_TOOLS_PATH\Microsoft.v5.5.2.PowerShell_profile.ps1"   # match the installed IDF version
+Set-Location "<repo-root>"
+idf.py build 2>&1 | Select-Object -Last 250
+```
+
+This is Windows-specific setup (the main dev works on Linux, where `idf.py` is normally
+already on PATH via `export.sh`/`. ./export.sh` or a shell profile).
+
+## Devicetree
+
+A device implementation has a `.dts` file.
+The parser at `Buildscripts/DevicetreeCompiler/` converts DTS into C code.
+It's called from the `Firmware/` build process.
+
+## 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 --test-dir Tests

+# 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** (Tactility, apps, services): `UpperCamelCase` for files and types. `lowerCamelCase` for functions. Files in `Source/`, `Include/`, `Private/` directories.
+
+For projects that emit C headers and have a C++ implementation file: the internal C++ function naming should be snake_case.
+
+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` when writing C++ code.
+Do not add redundant null checks for parameters with an explicit non-null precondition.
+
+Code Comments:
+
+- Should be as short as possible, leaving only important context.
+- Should avoid explaining what the code does, unless the code complexity is high enough to warrant an explanation.
+- Must avoid explaining how the code was before, or how it was changed.
+- Should explain why code is implemented.
+- Should be as brief as possible without losing critical information.
+- Should avoid explaining what was not implemented.
+- Should avoid referring to designs of other subsystems.
+- Must avoid interjections: avoid hyphens or braces to interject. If interjections provide crucial info, use Doxygen entity/anchor references like:
+/**
+ * A dedicated completion \signal for one app instance's task.
+ * Whichever \side finishes with it last is the one that deletes `semaphore` and frees this struct.
+ *
+ * \signal Not the task's shared default FreeRTOS notification, which app_event.cpp's AppEventSubscription also uses.
+ *     An unrelated event delivered to the same task could otherwise unblock a waiter early.
+ * \side The exiting task or a concurrent app_scheduler_stop() that found the entry in time and is waiting on `semaphore`.

+## Driver
+
+A driver generally consists of:
+- Registration of driver in parent module (optional, but desirable)
+- 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. C implementations are allowed, but C++ is preferred.
+
+Drivers are part of a kernel module.
+
+Modules with drivers can be stored in:
+- TactilityKernel
+- A subproject in `Platforms` folder
+- A subproject in `Devices` folder
+- A subproject in `Drivers` folder
+
+## Kernel Modules
+
+Kernel module names are lower case and postfixed with `-module`.
+
+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
+```

+- The `Drivers/` directory contains hardware drivers (display controllers, touch controllers, PMICs, etc.) — each is its own CMake component.
+- `Modules/` contains cross-cutting modules. e.g.`lvgl-module` (LVGL task management).
+- `Data/system/` and `Data/data/` are flashed as FAT filesystem images on ESP32.

+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.
+
+Two kernel modules cover LVGL:
+
+- **`lvgl-module`** (`Modules/lvgl-module/`, `<lvgl/*.h>`) owns LVGL's lifecycle: init/deinit, the LVGL task loop, and `lvgl_lock()`/`lvgl_try_lock()`/`lvgl_unlock()` mutex-based locking that any task must hold before touching LVGL objects. It bridges Tactility's device model to LVGL indevs (`lvgl/devices/*.h`: `display`, `pointer`, `keyboard`, `trackball`), and provides shared fonts (`lvgl/fonts.h`: Montserrat text sizes, Material Symbols icon sets for statusbar/launcher/shared use) and a few shared widgets (`lvgl/widgets/*.h`: `toolbar`, `spinner`, `sliderbox`).
+- **`lvgl-window-manager-module`** (`Modules/lvgl-window-manager-module/`, `<lvgl_window_manager/*.h>`) manages a single stacked window per app instance on top of `lvgl-module`. `window_manager_start()`/`window_manager_stop()` create/tear down the root widget (plus optional chrome from a configured `WindowManagerScreenInitFn`); `window_manager_create()`/`window_manager_remove()` push/pop an app's window and (re)populate it via a `WindowCreateWidgetsFn`. Only the topmost window ever has live widgets - burying and resurfacing a window deletes and rebuilds its widget tree rather than hiding/showing it. That rebuild-on-remove path can run `create_widgets` on a *different* app's thread (whichever app's `window_manager_remove()` call caused this window to resurface), so `create_widgets` must only rebuild already-committed state, never decide what happens next - state transitions belong in the app's own `main()` event loop, driven by real `APP_EVENT_RESULT`s.

+#### 3. Grant of Patent License
+
+Subject to the terms and conditions of this License, each Contributor hereby
+grants to You a perpetual, worldwide, non-exclusive, no-charge, royalty-free,
+irrevocable (except as stated in this section) patent license to make, have
+made, use, offer to sell, sell, import, and otherwise transfer the Work, where
+such license applies only to those patent claims licensable by such Contributor
+that are necessarily infringed by their Contribution(s) alone or by combination
+of their Contribution(s) with the Work to which such Contribution(s) was
+submitted. If You institute patent litigation against any entity (including a
+cross-claim or counterclaim in a lawsuit) alleging that the Work or a
+Contribution incorporated within the Work constitutes direct or contributory
+patent infringement, then any patent licenses granted to You under this License
+for that Work shall terminate as of the date such litigation is filed.
+
+#### 4. Redistribution
+
+You may reproduce and distribute copies of the Work or Derivative Works thereof
+in any medium, with or without modifications, and in Source or Object form,
+provided that You meet the following conditions:
+
+* **(a)** You must give any other recipients of the Work or Derivative Works a copy of
+this License; and
+* **(b)** You must cause any modified files to carry prominent notices stating that You
+changed the files; and
+* **(c)** You must retain, in the Source form of any Derivative Works that You distribute,
+all copyright, patent, trademark, and attribution notices from the Source form
+of the Work, excluding those notices that do not pertain to any part of the
+Derivative Works; and
+* **(d)** If the Work includes a “NOTICE” text file as part of its distribution, then any
+Derivative Works that You distribute must include a readable copy of the
+attribution notices contained within such NOTICE file, excluding those notices
+that do not pertain to any part of the Derivative Works, in at least one of the
+following places: within a NOTICE text file distributed as part of the
+Derivative Works; within the Source form or documentation, if provided along
+with the Derivative Works; or, within a display generated by the Derivative
+Works, if and wherever such third-party notices normally appear. The contents of
+the NOTICE file are for informational purposes only and do not modify the
+License. You may add Your own attribution notices within Derivative Works that
+You distribute, alongside or as an addendum to the NOTICE text from the Work,
+provided that such additional attribution notices cannot be construed as
+modifying the License.
+
+You may add Your own copyright statement to Your modifications and may provide
+additional or different license terms and conditions for use, reproduction, or
+distribution of Your modifications, or for any such Derivative Works as a whole,
+provided Your use, reproduction, and distribution of the Work otherwise complies
+with the conditions stated in this License.
+
+#### 5. Submission of Contributions
+
+Unless You explicitly state otherwise, any Contribution intentionally submitted
+for inclusion in the Work by You to the Licensor shall be under the terms and
+conditions of this License, without any additional terms or conditions.
+Notwithstanding the above, nothing herein shall supersede or modify the terms of
+any separate license agreement you may have executed with Licensor regarding
+such Contributions.
+
+#### 6. Trademarks
+
+This License does not grant permission to use the trade names, trademarks,
+service marks, or product names of the Licensor, except as required for
+reasonable and customary use in describing the origin of the Work and
+reproducing the content of the NOTICE file.
+
+#### 7. Disclaimer of Warranty
+
+Unless required by applicable law or agreed to in writing, Licensor provides the
+Work (and each Contributor provides its Contributions) on an “AS IS” BASIS,
+WITHOUT WARRANTIES OR CONDITIONS OF ANY KIND, either express or implied,
+including, without limitation, any warranties or conditions of TITLE,
+NON-INFRINGEMENT, MERCHANTABILITY, or FITNESS FOR A PARTICULAR PURPOSE. You are
+solely responsible for determining the appropriateness of using or
+redistributing the Work and assume any risks associated with Your exercise of
+permissions under this License.
+
+#### 8. Limitation of Liability
+
+In no event and under no legal theory, whether in tort (including negligence),
+contract, or otherwise, unless required by applicable law (such as deliberate
+and grossly negligent acts) or agreed to in writing, shall any Contributor be
+liable to You for damages, including any direct, indirect, special, incidental,
+or consequential damages of any character arising as a result of this License or
+out of the use or inability to use the Work (including but not limited to
+damages for loss of goodwill, work stoppage, computer failure or malfunction, or
+any and all other commercial damages or losses), even if such Contributor has
+been advised of the possibility of such damages.
+
+#### 9. Accepting Warranty or Additional Liability
+
+While redistributing the Work or Derivative Works thereof, You may choose to
+offer, and charge a fee for, acceptance of support, warranty, indemnity, or
+other liability obligations and/or rights consistent with this License. However,
+in accepting such obligations, You may act only on Your own behalf and on Your
+sole responsibility, not on behalf of any other Contributor, and only if You
+agree to indemnify, defend, and hold each Contributor harmless for any liability
+incurred by, or claims asserted against, such Contributor by reason of your
+accepting any such warranty or additional liability.
