 ### 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.

 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.

 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`.
