+
+## Project Overview
+
+Raman TUI: a Windows terminal application for controlling Raman spectrometers and filter wheels. The TUI accepts text commands (e.g. `spec scan`, `filter connect f1`) and also supports natural-language input via a DeepSeek LLM agent that translates prompts into those commands.
+
+## Build & Test Commands
+
+```bash
+# Build everything (solution file is roman.slnx, not .sln)
+dotnet build roman.slnx
+
+# Run all tests (xUnit)
+dotnet test roman.slnx
+
+# Run a single test project
+dotnet test test/Roman.Host.Tests
+dotnet test test/Raman.TUI.Tests
+
+# Run a single test by filter
+dotnet test test/Roman.Host.Tests --filter "FullyQualifiedName~DiscoverFiltersUseCaseTests"
+
+# Run the TUI in simulation mode (no hardware needed)
+dotnet run --project src/Raman.TUI -- --simulate
+```
+
+The target framework is **net10.0**. The solution uses the `.slnx` format (XML-based solution file).
+
+## Architecture
+
+### Layer structure (bottom to top)
+
+**Raman.Core** — Hardware abstractions. Defines `ISpectrometerDevice`, `IFilterWheelDevice`, and their associated data types (settings, capabilities, spectra). No implementations here.
+
+**Spec.Sea** — Spectrometer driver for the Sea SDK. Wraps a native C DLL (`SeaSDK.dll`) via `LibraryImport` P/Invoke in `SeaSdkNativeMethods`. `SeaSdkGateway` provides a managed facade; `SeaSpectrometerDevice`/`SeaSpectrometerDiscovery` implement the Core interfaces. Uses `AllowUnsafeBlocks`. The native DLL lives outside this repo at `../main/externals/SeaSDK.dll` and is copied to output.
+
+**Filter.Ello** — Filter wheel driver for Elliptec serial-protocol devices. Communicates over COM ports (`System.IO.Ports`). `SerialProtocol` encodes/decodes the Elliptec hex-based command format. Supports 4-slot and 6-slot wheels.
+
+**Raman.Simulator** — In-memory fakes of both spectrometers and filter wheels. Used for development and testing without hardware. Activated by `--simulate` flag or `RAMAN_TUI_SIMULATE=1` env var.
+
+**Roman.Host** — Business logic orchestration layer. Contains:
+- `SpectrometerRuntimeWorkspace` / `FilterRuntimeWorkspace` — stateful command dispatchers that manage device lifecycle (discover, connect, configure, acquire, disconnect).
+- Request/response contracts (`SpectrometerRequest`/`SpectrometerResponse`, `FilterRequest`/`FilterResponse`) with command-kind enums.
+- Filter discovery subsystem that scans COM ports for Elliptec devices.
+- Filter configuration persistence (JSON-based `FilterConfigurationStore`).
+
+**Raman.TUI** — The terminal application. Key components:
+- `ICommandSession` — interface for command handlers. `FilterCommandSession` and `SpectrometerCommandSession` parse text commands and delegate to Roman.Host workspaces. `CompositeCommandSession` routes to the right handler.
+- `InlineConsoleApp` — custom TUI rendering engine using low-level `Console` APIs and a Windows-specific `ConsoleInputReader` (reads raw input events). Manages a scrollable log of `NotificationEntry` items and a single-line input bar.
+- `DeepSeekLlmSession` — LLM integration via `Microsoft.Agents.AI.OpenAI`. Configured from `raman-agent.toml` (TOML format, loaded from app base directory). Environment variables `DEEPSEEK_API_KEY` and `DEEPSEEK_MODEL` override the config file.
+
+**RamanTester** — Standalone x86 console app for direct Sea SDK testing. Targets x86 (`PlatformTarget=x86`) because the native Sea SDK DLL is 32-bit.
+
+### Key patterns
+
+- Commands flow as: user text -> `ICommandSession.ExecuteAsync` -> `*RuntimeWorkspace.HandleAsync` -> `ISpectrometerDevice`/`IFilterWheelDevice` method.
+- All command sessions return `IReadOnlyList<NotificationEntry>` which the TUI renders as log lines.
+- Background commands use `publishAsync` callback to stream entries to the UI incrementally.
+- The LLM agent uses tool calling — `TuiLlmCommandTool.RunTuiCommandAsync` executes TUI commands on behalf of the LLM and returns results as text.
+
+## Code Conventions
+
+- File-scoped namespaces (`csharp_style_namespace_declarations = file_scoped`).
+- LF line endings, UTF-8, spaces for indentation.
+- 2-space indent for XML/csproj files.
+- Commit messages are in Chinese.
+- The project language mixes English (code) and Chinese (UI strings, LLM instructions, commit messages).
