+# ARStack61850 SMV Injection Studio
+
+Native Slint desktop workstation for fast IEC 61850-9-2 Sampled Values injection.
+
+The interface combines the fast numeric workflow of professional test equipment with a modern, calm three-view workspace. It uses original ARStack61850 styling and does not copy OMICRON or ARSVIN product assets.
+
+## Operator workflow
+
+- Quick Manual table for 4 voltage and 4 current channels.
+- Arrow keys move between magnitude, angle, and frequency cells.
+- Enter validates and commits; focus selects the complete value for immediate replacement.
+- Invalid values remain focused and never reach the device command path.
+- Live Apply transmits validated edits to the next coherent generation.
+- Phasor and waveform views update from the effective editor state.
+- Start, running timer, Stop, TX sequence, and publisher state remain visible during injection.
+- Status History and Overload Monitor live in a collapsible lower dock.
+- Lucide icons provide a consistent command vocabulary.
+
+## Native controller
+
+The C++ controller owns validation and Windows serial transport. The current command protocol is:
+
+```text
+SET <channel> <magnitude-counts> <phase-millidegrees> 0
+FREQ <millihertz>
+ENABLE <channel> <0|1>
+START
+STOP
+ZERO
+SHOW
+```
+
+Default validation limits are 0-10,000 A RMS, 0-1,000,000 V RMS, -360 to 360 degrees, and 1-1,000 Hz. Profile identity and layout changes remain a STOP -> validate -> deploy operation; mutable values use the live-control path.
+
+## Windows quick start
+
+Requirements: CMake 3.21+, a C++20 MSVC toolchain, and Rust 1.92+ when Slint is fetched from source.
+
+From the repository root:
+
+```powershell
+.\apps\smv_injector_slint\run.cmd
+```
+
+On systems with a `D:` drive, the launcher defaults to:
+
+```text
+D:\Build\arstack61850-smv-slint
+D:\Tools\Slint\1.17.1
+```
+
+Override either location with `ARSTACK_BUILD_DIR` or `ARSTACK_SLINT_DEPS_DIR`. The CMake target copies `slint_cpp.dll` beside the executable after every successful Windows build, preventing a missing-runtime startup error.
+
+## Manual build
+
+```powershell
+cmake -S apps/smv_injector_slint -B build-smv-slint -DCMAKE_BUILD_TYPE=Release
+cmake --build build-smv-slint --target arstack_smv_slint_shell --config Release
+```
+
+Set `-DARSTACK_SLINT_FETCH=OFF` to require an installed Slint C++ package.
+
+## Architecture boundary
+
+```text
+Slint workstation views
+        |
+        v
+C++ validation and presentation controller
+        |---------------------------|
+        v                           v

+             ESP32-P4 mutable state

+                      v
+              realtime SMV publisher
+```
+
+The UI is never the realtime waveform scheduler.
