+# Repository Guidelines
+
+## Build Prerequisites
+
+- **Linux**: `libudev-dev` (for `serialport`).
+- **All platforms**: a C compiler (`cc`, `gcc`, `clang`, or MSVC) — `mlua` uses `features = ["vendored"]` which compiles LuaJIT from source at build time.
+- **No pinned toolchain**: all crates use `edition = "2024"` (requires Rust ≥ 1.85). No `rust-toolchain.toml`; builds with whatever `rustc` is on `PATH`.
+
+## Project Structure
+
+`xserial` is a Rust workspace. The root `Cargo.toml` defines four crates in `crates/`, with dependencies flowing:
+
+```
+xserial-core  (no internal deps — transport, framing, protocol, pipeline)
+     ↑
+xserial-client  (depends on xserial-core — sessions, history, commands, Lua)
+  ↑        ↑
+xserial-gui   xserial-tui
+(both depend on xserial-core AND xserial-client)
+```
+
+| Crate | Type | What goes here |
+|-------|------|---------------|
+| `xserial-core` | library (`src/lib.rs`) | `transport/`, `frame/`, `protocol/`, `pipeline.rs` — protocol and I/O. Integration tests: `tests/pipeline.rs`. |
+| `xserial-client` | library (`src/lib.rs`) | `session.rs`, `manager.rs`, `config.rs`, `history.rs`, `lua/` — state management and Lua bindings. Integration tests: `tests/session_lifecycle.rs`, `tests/lua_tests.rs`. |
+| `xserial-gui` | binary (`src/main.rs`) | egui/eframe app. Panels in `src/panels/`. Font helpers in `src/ui_fonts.rs`. Profiling in `src/perf.rs`. |
+| `xserial-tui` | binary (`src/main.rs`) | ratatui/crossterm app. **Still a placeholder** — zero tests, not at feature parity with GUI. |
+
+**Module boundaries**: transport/protocol → `xserial-core`. Session/Lua → `xserial-client`. UI state → `xserial-gui` or `xserial-tui`. Never put I/O logic in the UI crates, never put UI state in the client crate.
+
+## Build, Test, and Development Commands
+
+```bash
+cargo check --workspace              # fast compile check (all crates)
+cargo test --workspace               # full suite (~266 tests)
+cargo fmt --all                      # standard Rust formatting
+cargo clippy --workspace --all-targets -- -D warnings   # lint gate
+```
+
+**Run specific tests:**
+
+```bash
+cargo test -p xserial-core -- tcp_line_text_utf8
+cargo test -p xserial-client -- session_echo_send_and_read
+cargo test -p xserial-core -- --nocapture          # show test output
+
+# Integration tests only
+cargo test -p xserial-core --test pipeline
+cargo test -p xserial-client --test session_lifecycle
+cargo test -p xserial-client --test lua_tests
+```
+
+**Launch:**
+
+```bash
+cargo run -p xserial-gui
+cargo run -p xserial-tui
+```
+
+## Environment & Configuration
+
+### Tracing (all entrypoints)
+
+```bash
+RUST_LOG=info cargo run -p xserial-gui
+RUST_LOG=xserial_gui::perf=debug cargo run -p xserial-gui
+```
+
+`tracing_subscriber::EnvFilter::from_default_env()` reads `RUST_LOG`. The workspace dep `tracing-subscriber` has `features = ["env-filter"]`.
+
+### GUI Profiling
+
+```bash
+RUST_LOG=xserial_gui::perf=info XSERIAL_GUI_PROFILE=1 cargo run -p xserial-gui
+XSERIAL_GUI_PROFILE_INTERVAL_MS=500 cargo run -p xserial-gui    # custom interval (default 1s)
+```
+
+Profiling logs go to target `xserial_gui::perf`.
+
+### State & Config File Paths (runtime, not compile-time)
+
+Uses `env::consts::OS` + env vars — no `cfg(target_os)` gating for path resolution:
+
+| Platform | Root config path |
+|----------|-----------------|
+| Linux | `$XDG_CONFIG_HOME/xserial/` or `~/.config/xserial/` |
+| macOS | `~/Library/Application Support/xserial/` |
+| Windows | `%APPDATA%\xserial\` |
+
+State files: `gui-state.json`, `tui-state.json`, `font-settings.json`.
+
+### GUI Plot Testing
+
+```bash
+python tools/test_plot.py --wire-format mixed --host 127.0.0.1 --port 8091
+python tools/test_plot.py --wire-format mixed --format xy --channels 2
+python tools/test_plot.py --wire-format raw --channels 2 --framelen 256
+```
+
+Configure in GUI: Transport `TCP 127.0.0.1:8091`, Framer `MixedTextPlot`, Decoder `MixedTextPlot`.
+
+The wire format spec lives in `tools/xs_mixed_plot.h` (C header, reference only — not compiled into Rust).
+
+## Coding Style
+
+Standard Rust conventions (`cargo fmt`). No crate-level lint attrs, no `[lints]` table in any `Cargo.toml`. Names: `snake_case` for modules/files/functions/tests, `PascalCase` for types, `SCREAMING_SNAKE_CASE` for constants.
+
+## Testing Guidelines
+
+- **Inline unit tests** (`#[cfg(test)] mod tests`) next to implementation — 24 source files with `#[test]` or `#[tokio::test]`.
+- **Integration tests** in `crates/<crate>/tests/*.rs` — 3 files covering pipeline, session lifecycle, and Lua bindings.
+- **~266 tests total** — all active (zero `#[ignore]`). Single `#[should_panic]` in `frame/fixed.rs`.
+- **All tests are self-contained**: TCP/UDP bind to `127.0.0.1:0` (OS-assigned port). No hardcoded ports. No external services. Serial tests use dummy port names and never open real hardware.
+- **Async tests** use `#[tokio::test]` (no `async-std`). **No benchmarks** exist.
+- Run `cargo test --workspace` before opening PRs. Add targeted regression tests for transport, framing, parsing, and session-state fixes.
+
+## Known Quirks & Constraints
+
+- **No CI** — no `.github/workflows` or other CI config. Agents must self-verify with `cargo test --workspace` and `cargo clippy --workspace --all-targets -- -D warnings`.
+- **No feature flags** — zero `[features]` in any `Cargo.toml`. No `#[cfg(feature)]` in any source.
+- **No build scripts** — zero `build.rs` files. No codegen. No `include!`/`include_str!`/`include_bytes!`.
+- **All `unsafe` is test-only** — constructing noop wakers for poll-based unit tests in `transport/`. No non-test `unsafe` anywhere.
+- **`xserial-tui` is a stub** — no tests, minimal implementation. GUI is the primary target.
+- **Platform font directories** use `#[cfg(target_os)]` in `ui_fonts.rs` (three blocks: Windows, macOS, Linux/BSD).
+- **`tokio` features differ by build**: `xserial-client` uses `["sync", "time"]` for production, `["full"]` for dev-dependencies (tests need net/IO).
+
+## Commit & PR Guidelines
+
+Short, imperative subjects (`Persist GUI font settings`), occasional `feat:` prefix for major additions. PRs: state which crate(s) changed, list validation commands, include screenshots/recordings for GUI/TUI changes. Explicitly call out protocol, transport, or Lua API compatibility impacts.
+
+## Reference
+
+- `tools/test_plot.py --help` — TCP plot-frame generator options.
+- `tools/xs_mixed_plot.h` — wire format spec for MixedTextPlot (COBS-framed binary plot + text on one stream).

-```
-
-### 步骤 1：启动测试数据源
-
-```bash
-python tools/test_drone.py --rate 10 --port 8091
-```
-
-输出：
-
-```
-Listening on 127.0.0.1:8091, waiting for connections...
-```
-
-### 步骤 2：配置 Session
-
-在 pipeview-gui 中创建 Session：
-
-| 配置项 | 值 |
-|--------|-----|
-| Transport | `TCP 127.0.0.1:8091` |
-| Pipeline 1 | Framer: `Line` → Decoder: `Lua` → 选择 `examples/drone_text.lua` |
-| Pipeline 2 | Framer: `Line` → Decoder: `Lua` → 选择 `examples/drone_plot.lua` |
-
-### 步骤 3：查看结果
-
-- **文本视图** — 显示格式化的传感器数据
-- **波形视图** — 显示 Gyro 三轴实时曲线 (gz/gy/gx)
-
-`examples/drone_plot.lua` 的核心逻辑：
-
-```lua
-return {
-    decode = function(frame)
-        local gz, gy, gx = frame:match("Gyro:([%d%.%-]+),([%d%.%-]+),([%d%.%-]+)")
-        return {
-            kind = "plot",
-            channels = { { tonumber(gz) }, { tonumber(gy) }, { tonumber(gx) } },
-            sample_type = "F64",
-            format = "Block",
-        }
-    end,

-## Lua 脚本开发指南
-
-### 分帧器 API
-
-分帧器将原始字节流切分为帧，Lua 脚本必须返回包含以下函数的 table：
-
-```lua
-return {
-    -- 输入新到达的字节，返回帧数组（Lua strings）
-    feed = function(bytes)
-        -- bytes: Lua string（原始字节）
-        -- 返回: { frame1, frame2, ... } 或 nil
-    end,
-
-    -- 刷新缓冲区中残留的数据
-    flush = function()
-        -- 返回: 最后一帧（Lua string）或 nil
-    end,
-
-    -- 重置内部状态
-    reset = function()
-    end,
-
-    -- 返回缓冲区中待处理的字节数
-    pending_len = function()
-        -- 返回: number
-    end,
-}
-```
-
-参考实现：`crates/pipeview-client/tests/fixtures/lua_line_framer.lua`（按 `\n` 分割的行分帧器）
-
-### 解码器 API
-
-解码器将帧解析为结构化数据，Lua 脚本必须返回包含 `decode` 函数的 table：
-
-```lua
-return {
-    decode = function(frame)
-        -- frame: Lua string（来自分帧器的一帧）
-        -- 返回 nil → 跳过此帧
-        -- 返回 string → 自动视为 Text
-        -- 返回 table → 必须包含 kind 字段
-    end,
-}
-```
-
-**返回值格式：**
-
-| `kind` | 必需字段 | 可选字段 | 用途 |
-|--------|----------|----------|------|
-| `"text"` | `data: string` | — | 文本视图 |
-| `"hex"` | `data: string` | — | 十六进制视图 |
-| `"binary"` | `data: string` | — | 原始二进制 |
-| `"plot"` | `channels: {{number,…},…}` | `sample_type`、`format` | 波形视图 |
-
-**Plot 返回值示例：**
-
-```lua
-return {
-    kind = "plot",
-    channels = {
-        { 1.0, 2.0, 3.0 },  -- channel 0
-        { 4.0, 5.0, 6.0 },  -- channel 1

-## Features
-
-### Transport
-
-| Type | Description | Options |
-|------|-------------|---------|
-| **Serial** | Serial port communication | Port name, baud rate (300–12M), data bits (5/6/7/8), parity (None/Odd/Even), stop bits (1/2), flow control (None/Software/Hardware), DTR/RTS control |
-| **TCP** | TCP client | Target address `host:port` |
-| **UDP** | UDP communication | Bind address `host:port`, optional remote address |
-
-### Framers
-
-Framers split raw byte streams into discrete frames. Each session supports **multiple independent pipelines** — the same byte stream feeds multiple framer→decoder chains in parallel.
-
-| Framer | Description | Parameters |
-|--------|-------------|------------|
-| **Line** | Split by `\n` | `strip_cr`, `max_line_len` |
-| **Fixed** | Fixed-length frames | `frame_len` |
-| **Length** | Length-prefixed protocol | `len_bytes` (1/2/4/8), `endian`, `length_includes_self`, `max_payload` |
-| **COBS** | [Consistent Overhead Byte Stuffing](https://en.wikipedia.org/wiki/Consistent_Overhead_Byte_Stuffing) | `max_frame` |
-| **MixedTextPlot** | Hybrid text lines + COBS-encoded plot frames on one stream | `strip_cr`, `max_line_len`, `max_plot_frame` |
-| **Lua** | User-defined framer script | `script_path` |
-
-### Decoders
-
-Decoders parse framed data into displayable content.
-
-| Decoder | Output | Parameters |
-|---------|--------|------------|
-| **Text** | Text | `encoding` (UTF-8 / Latin1 / ASCII) |
-| **Hex** | Hexadecimal | `uppercase`, `separator`, `bytes_per_group`, `endian` |
-| **Plot** | Waveform | `sample_type` (i8–f64), `endian`, `channels` (1–64), `format` (Interleaved / Block / XY) |
-| **MixedTextPlot** | Hybrid text + waveform | `encoding` |
-| **Lua** | Custom | `script_path` |
-
-**Plot sample formats:**
-
-| Format | Description | Byte layout |
-|--------|-------------|-------------|
-| **Interleaved** | Channels interleaved | `[ch0_s0, ch1_s0, ch2_s0, ch0_s1, ch1_s1, …]` |
-| **Block** | Channel-contiguous blocks | `[ch0_s0, ch0_s1, …, ch1_s0, ch1_s1, …]` |
-| **XY** | 2-channel x/y pairs | `[x0, y0, x1, y1, …]` |
-
-Supported sample types: `i8`, `u8`, `i16`, `u16`, `i32`, `u32`, `i64`, `u64`, `f32`, `f64`
-
-### Views
-
-- **Text View** — formatted text with timestamps, direction markers (`[IN]`/`[OUT]`), and pipeline labels. Built-in search (`Ctrl+F`) with case-sensitive toggle, match counter, and highlighting.
-- **Hex View** — hex dump alongside ASCII sidebar. Configurable byte grouping and endianness.
-- **Plot View** — real-time waveforms via [egui_plot](https://github.com/emilk/egui/tree/master/crates/egui_plot). Auto-fit, box zoom, axis locking, follow-latest, detached window, channel legend.
-
-### Sessions
-
-- **Multi-session** — tabbed interface, each session independently configured
-- **Connection control** — Connect / Disconnect / Reconnect with auto-reconnect on drop
-- **Live reconfiguration** — change framer/decoder settings without restarting
-- **Data sending** — Text mode (UTF-8, configurable line endings) and Hex mode (raw bytes). Four line ending options: None / LF / CR / CRLF
-- **Ring buffer** — default 10,000 entries, configurable 100–1,000,000
-- **Log to file** — background writer thread with 1 KB buffer, non-blocking
-- **Search** — `Ctrl+F` search bar, case-sensitive toggle, F3/Shift+F3 navigation
-
-### Lua Scripting
-
-Built-in LuaJIT runtime:
-
-- **Custom framers** — implement `feed(bytes)`, `flush()`, `reset()`, `pending_len()`
-- **Custom decoders** — implement `decode(frame)`, return text/hex/plot/binary
-- **Session API** — `pipeview.open()` to create sessions, `session:on_data()` for event callbacks, `session:send()` to transmit data
-- **Utilities** — `pipeview.list_ports()`, `pipeview.sleep(ms)`, `pipeview.poll(limit)`, `pipeview.log(msg)`

-## Walkthrough: Drone Telemetry
-
-Parse Betaflight/INAV flight controller telemetry in the format:
-
-```
-AHRS q:1.0000,0.0998,0.0499,0.0200|YPR:8.87,4.44,2.96|Gyro:14.78,8.87,5.92|RC:1559,1544,1500,1519|M:1612,1588,1603,1597|L:0 F:1 C:0
-```
-
-### Step 1: Start the data source
-
-```bash
-python tools/test_drone.py --rate 10 --port 8091
-```
-
-### Step 2: Configure the session
-
-In pipeview-gui, create a session with two pipelines:
-
-| Setting | Value |
-|---------|-------|
-| Transport | `TCP 127.0.0.1:8091` |
-| Pipeline 1 | Framer: `Line` → Decoder: `Lua` → `examples/drone_text.lua` |
-| Pipeline 2 | Framer: `Line` → Decoder: `Lua` → `examples/drone_plot.lua` |
-
-### Step 3: View the results
-
-- **Text View** — formatted sensor readouts
-- **Plot View** — real-time gyroscope curves (gz/gy/gx)
-
-The decoder in `examples/drone_plot.lua`:
-
-```lua
-return {
-    decode = function(frame)
-        local gz, gy, gx = frame:match("Gyro:([%d%.%-]+),([%d%.%-]+),([%d%.%-]+)")
-        return {
-            kind = "plot",
-            channels = { { tonumber(gz) }, { tonumber(gy) }, { tonumber(gx) } },
-            sample_type = "F64",
-            format = "Block",
-        }
-    end,
-}
-```
-

-
-## Lua Scripting Guide
-
-### Framer API
-
-A Lua framer splits raw bytes into frames. The script must return a table with these functions:
-
-```lua
-return {
-    feed = function(bytes)
-        -- bytes: Lua string (raw bytes)
-        -- Returns: { frame1, frame2, ... } or nil
-    end,
-
-    flush = function()
-        -- Returns: last buffered frame (string) or nil
-    end,
-
-    reset = function()
-    end,
-
-    pending_len = function()
-        -- Returns: number of bytes pending in buffer
-    end,
-}
-```
-
-Reference: `crates/pipeview-client/tests/fixtures/lua_line_framer.lua` (line-based framer splitting on `\n`).
-
-### Decoder API
-
-A Lua decoder parses a frame into structured data. The script must return a table with a `decode` function:
-
-```lua
-return {
-    decode = function(frame)
-        -- frame: Lua string (one frame from the framer)
-        -- Returns nil → skip this frame
-        -- Returns string → treated as Text
-        -- Returns table → must contain "kind" field
-    end,
-}
-```
-
-**Return value formats:**
-
-| `kind` | Required | Optional | Purpose |
-|--------|----------|----------|---------|
-| `"text"` | `data: string` | — | Text view |
-| `"hex"` | `data: string` | — | Hex view |
-| `"binary"` | `data: string` | — | Raw bytes |
-| `"plot"` | `channels: {{number,…},…}` | `sample_type`, `format` | Plot view |
-
-**Plot return value example:**
-
-```lua
-return {
-    kind = "plot",
-    channels = {
-        { 1.0, 2.0, 3.0 },  -- channel 0
-        { 4.0, 5.0, 6.0 },  -- channel 1
-    },
-    sample_type = "F64",    -- default F64; also I8/U8/I16/U32/U64/F32
-    format = "Block",       -- default Interleaved; also Block/XY
-}
-```

-| Crate | Type | Purpose |
-|-------|------|---------|
-| `pipeview-core` | library | Transport (Serial/TCP/UDP), framers (Line/Fixed/Length/COBS/Mixed/Lua), decoders (Text/Hex/Plot), MultiPipeline |
-| `pipeview-client` | library | Session lifecycle, SessionManager, event broadcast (tokio broadcast), RingBuffer history, Lua runtime & session API |
-| `pipeview-gui` | binary | egui desktop app: sidebar, config, console, text/hex/plot panels, keyboard shortcuts, font management, profiling |
-
-**Dependency flow:** `core ← client ← gui`
-
-**Data flow:**
-
-```
-[Transport] → read bytes → [MultiPipeline]
-    → Pipeline 1: Framer → Decoder → DecodedEntry → broadcast → GUI buffers
-    → Pipeline 2: Framer → Decoder → DecodedEntry → broadcast → GUI buffers
-    → ...
-```
-
-Each pipeline frames and decodes independently. Only successful decodes produce output.
-
----
-
-## Configuration & Persistence
-
-GUI state is saved automatically to platform-standard locations:
-
-| Platform | Path |
-|----------|------|
-| Linux | `$XDG_CONFIG_HOME/pipeview/gui-state.json` or `~/.config/pipeview/gui-state.json` |
-| macOS | `~/Library/Application Support/pipeview/gui-state.json` |
-| Windows | `%APPDATA%\pipeview\gui-state.json` |
-
-Persisted data includes: session configurations (transport, pipelines), log settings, active tab, and display options.
-
-Log files are written to `logs/` under the config directory, named `session_{id}_{timestamp}.log`.
