+# G-code F 进给速度驱动 RUN 执行修复文档
+
+生成时间：2026-06-22
+
+## 1. 问题结论
+
+当前 `RUN` 链路已经能完成：
+
+```text
+1. 打开 LinuxCNC G-code 程序。
+2. 通过 task/HAL runtime 推进状态。
+3. 更新当前行、高亮行、DRO、axisPose、执行轨迹和 task/HAL feedback。
+```
+
+但当前 `RUN` **还没有按 G-code 的真实进给速度执行**。
+
+当前关键问题：
+
+```text
+G-code interpreter 能解析 F。
+execution-timing.js 能基于 F / 距离 / INI 限速做 feed-based timing estimate。
+但是 task/HAL RUN 执行链路没有把 F 用作真实运行速度。
+C++ wrapper 层固定写入 velocity=60。
+activeLine 按 task cycle 推进一行，而不是按 段距离 / F / elapsed time 推进。
+```
+
+因此现有浏览器 RUN 证据只能证明：
+
+```text
+task/HAL feedback 正在产生；
+UI 当前行与 task/HAL active line 同步；
+DRO 与 runtime axisPose 同步；
+执行轨迹可见；
+```
+
+不能证明：
+
+```text
+程序按 G-code F 进给速度、G93/G94 模态、rapid/feed 区分、override、段距离真实定时执行。
+```
+
+## 2. 当前源码证据
+
+### 2.1 固定 velocity=60
+
+文件：
+
+```text
+wasm-port/runtime/core/linuxcnc_wrap/linuxcnc_task_hal_wasm.cpp
+```
+
+函数：
+
+```text
+enqueue_linear_move_from_line(TaskRuntime &state, const std::string &line)
+```
+
+当前逻辑：
+
+```cpp
+command << ",\"velocity\":60}";
+```
+
+影响：
+
+```text
+1. 每条 G-code 运动行传给 motion runtime 的速度都是 60 units/s。
+2. JS 状态层把 currentVel * 60 转成 mm/min。
+3. 在 mm 单位下 UI 看到的速度固定为 3600 mm/min。
+4. G-code 行中的 F159 / F318 / F636 等不会影响 RUN 实际速度。
+```
+
+### 2.2 按 task cycle 推进一行
+
+文件：
+
+```text
+wasm-port/runtime/core/linuxcnc_wrap/linuxcnc_task_hal_wasm.cpp
+```
+
+函数：
+
+```text
+lctask_run_cycles(long task_period_ns, long servo_period_ns, int task_cycles)
+```
+
+当前逻辑：
+
+```cpp
+for (int i = 0; i < task_cycles; ++i) {
+    state.task_cycle += 1;
+    if (state.interp_state == "READING" && state.next_program_line < state.opened_line_count) {
+        enqueue_linear_move_from_line(state, state.program_lines[state.next_program_line]);
+        ...
+    }
+    lcmot_step_servo(...);
+}
+```
+
+影响：
+
+```text
+1. 每个 task cycle 至多 enqueue 一条程序行。
+2. active line 由 cycle 数推进。
+3. 长段、短段、F 快、F 慢不会改变行推进节奏。
+4. 这不是真实 LinuxCNC planner/task/motion 的时间语义。
+```
+
+### 2.3 interpreter 已有 F 信息
+
+文件：
+
+```text
+web-rtcp-5axis-sim-plan/app/src/runtime/linuxcnc-interpreter-runtime.js
+```
+
+已有能力：
+
+```text
+1. feedRatesBySourceLine(programText) 从 G-code 中提取 F。
+2. parseLinuxCncCanonicalMotion(...) 把 activeFeedRate 写入 motion event 的 feedRate。
+3. linearUnitsBySourceLine(...) 跟踪 G20/G21。
+```
+
+输出 motion event 已包含：
+
+```js
+{
+  type,
+  line,
+  axes,
+  feedRate,
+  linearUnits,
+  ...
+}
+```
+
+### 2.4 timing estimate 已有 F 计算
+
+文件：
+
+```text
+web-rtcp-5axis-sim-plan/app/src/runtime/execution-timing.js
+```
+
+已有能力：
+
+```text
+1. 按 motion event feedRate 计算 requestedLinearVelocity。
+2. 按 profile/INI max velocity 限速。
+3. 按 linear distance / angular distance 计算 segment durationSeconds。
+4. 处理 feedOverride / rapidOverride。
+```
+
+但当前边界是：
+
+```text
+semanticBoundary = linuxcnc_canonical_motion_timing_estimate_not_planner_queue
+```
+
+说明它是估算，不是 task/HAL RUN 的权威执行节奏。
+
+## 3. 修复目标
+
+### 3.1 必须达成
+
+修复后 `RUN` 必须满足：
+
+```text
+1. G-code 中 F 值进入 task/HAL RUN 执行链路。
+2. G94 units/min 模式下，feed move 的速度来自当前 modal F。
+3. G0/STRAIGHT_TRAVERSE 使用 rapid velocity / rapid override / INI max velocity。
+4. activeLine 按 elapsed execution time 与当前段完成度推进。
+5. 长距离低 F 段明显运行更久。
+6. 短距离高 F 段明显更快完成。
+7. UI currentVelocity 不再固定 3600 mm/min。
+8. DRO/axisPose 可以在段内插值，而不是只在行边界跳变。
+9. 现有 RUN gate、task/HAL session、status loop、STOP/ABORT/STEP 不回退。
+```
+
+### 3.2 第一阶段不强求
+
+以下可以作为第二阶段：
+
+```text
+1. 完整 LinuxCNC trajectory planner queue 动力学一致性。
+2. 加速度/jerk/圆弧真实插补完全对齐 LinuxCNC。
+3. G93 inverse-time feed 的完整五轴角度/线性混合真实语义。
+4. 硬件 realtime HAL 驱动。
+```
+
+但第一阶段至少不能继续固定 `velocity=60`。
+
+## 4. 推荐实现方案
+
+### 4.1 不要继续在 C++ wrapper 中逐行粗解析 G-code
+
+当前 C++ wrapper 的 `enqueue_linear_move_from_line()` 是字符串扫描：
+
+```text
+查找 XYZABC 字母；
+strtod 读取数值；
+没有模态；
+没有 F；
+没有 G90/G91；
+没有 G20/G21；
+没有 G93/G94；
+没有 G0/G1/G2/G3 区分；
+```
+
+这个方向继续扩展会很脆弱。
+
+推荐改为：
+
+```text
+JS interpreter runtime 继续负责生成 canonical motion events。
+JS 侧把 canonical motion + timing segments 传入 task/HAL runtime session。
+C++ task/HAL wrapper 不再直接解析 G-code 行来生成 velocity。
+C++ task/HAL wrapper 按已解析 motion segment 执行。
+```
+
+### 4.2 新增 task/HAL program motion plan
+
+在 `wasm-port/runtime/sdk/src/linuxcnc-task-hal.js` 增加可选 API：
+
+```js
+loadProgramMotionPlan({
+  programPath,
+  motion,
+  timing,
+  linearUnits,
+})
+```
+
+在 C++ wrapper 增加导出：
+
+```cpp
+int lctask_load_program_motion_plan_json(const char *plan_json);
+```
+
+motion plan 中至少包含：
+
+```json
+{
+  "programPath": "...",
+  "segments": [
+    {
+      "line": 8,
+      "type": "STRAIGHT_FEED",
+      "motionClass": "feed",
+      "axes": { "x": 6.302, "y": -11.560, "z": 27.743, "a": -71.841, "c": -35.930 },
+      "startAxes": { "...": 0 },
+      "feedRate": 318,
+      "linearUnits": "mm",
+      "velocityMmPerMin": 318,
+      "durationSeconds": 0.42,
+      "startSeconds": 1.25,
+      "elapsedSeconds": 1.67
+    }
+  ]
+}
+```
+
+### 4.3 C++ task runtime 状态新增字段
+
+`TaskRuntime` 增加：
+
+```cpp
+struct MotionSegment {
+    int line = 0;
+    std::string type;
+    std::string motion_class;
+    double start_seconds = 0.0;
+    double duration_seconds = 0.0;
+    double velocity_mm_per_min = 0.0;
+    std::map<std::string, double> start_axes;
+    std::map<std::string, double> end_axes;
+};
+
+std::vector<MotionSegment> motion_plan;
+int active_segment_index = 0;
+double run_elapsed_seconds = 0.0;
+double run_start_seconds = 0.0;
+```
+
+### 4.4 RUN 周期推进改为按 elapsed time
+
+当前：
+
+```text
+每 task cycle enqueue 一行。
+```
+
+修复后：
+
+```text
+每次 lctask_run_cycles 根据 task_period_ns * task_cycles 增加 run_elapsed_seconds。
+根据 run_elapsed_seconds 找到 active segment。
+按 segment progress 插值 axisPose。
+把 currentVel/requestedVel 设置为 segment.velocityMmPerMin / 60。
+activeLine = segment.line。
+segment 完成后才进入下一 segment。
+```
+
+伪代码：
+
+```cpp
+int lctask_run_cycles(long task_period_ns, long servo_period_ns, int task_cycles)
+{
+    const double delta_seconds = (task_period_ns / 1e9) * task_cycles;
+    state.run_elapsed_seconds += delta_seconds;
+
+    const MotionSegment *segment = find_segment_at_time(state.motion_plan, state.run_elapsed_seconds);
+    if (!segment) {
+        state.interp_state = "IDLE";
+        state.exec_state = "DONE";
+        return step_servo(...);
+    }
+
+    const double local = state.run_elapsed_seconds - segment->start_seconds;
+    const double progress = clamp(local / segment->duration_seconds, 0.0, 1.0);
+    AxisPose pose = interpolate(segment->start_axes, segment->end_axes, progress);
+
+    forward_motion_sample({
+        line: segment->line,
+        axes: pose,
+        currentVel: segment->velocity_mm_per_min / 60.0,
+        requestedVel: segment->velocity_mm_per_min / 60.0,
+        inPosition: progress >= 1.0
+    });
+
+    step_servo(...);
+}
+```
+
+### 4.5 motion runtime command schema
+
+当前 motion command 是：
+
+```json
+{
+  "type": "EMC_TRAJ_LINEAR_MOVE",
+  "line": 12,
+  "x": 1,
+  "velocity": 60
+}
+```
+
+建议新增或扩展为：
+
+```json
+{
+  "type": "EMC_TRAJ_LINEAR_SAMPLE",
+  "line": 12,
+  "x": 1.2,
+  "y": 3.4,
+  "z": 5.6,
+  "a": -70,
+  "c": 20,
+  "currentVel": 5.3,
+  "requestedVel": 5.3,
+  "segmentProgress": 0.35,
+  "source": "feed_timed_motion_plan"
+}
+```
+
+如果不想新增 command type，也可以继续使用 `EMC_TRAJ_LINEAR_MOVE`，但必须：
+
+```text
+1. velocity 来自 segment.velocityMmPerMin / 60。
+2. axes 是当前插值位置，而不是只用 segment end。
+3. status 能保留 line/progress/currentVel。
+```
+
+## 5. G94 速度规则
+
+### 5.1 G94 units per minute
+
+在 `TRAJ.LINEAR_UNITS=mm` 时：
+
+```text
+F318 => 318 mm/min
+```
+
+在 `TRAJ.LINEAR_UNITS=inch` 或 G20 active 时：
+
+```text
+F10 => 10 inch/min => 254 mm/min
+```
+
+计算：
+
+```text
+velocity_mm_per_min = feedRate * linearUnitScaleToMm * feedOverride
+duration_seconds = linearDistanceMm / (velocity_mm_per_min / 60)
+```
+
+### 5.2 Rapid
+
+G0 / `STRAIGHT_TRAVERSE`：
+
+```text
+velocity_mm_per_min = min(INI max velocity, profile max velocity) * rapidOverride
+duration_seconds = distance / velocity
+```
+
+### 5.3 Angular axes
+
+第一阶段可沿用 `execution-timing.js` 现有策略：
+
+```text
+linearSeconds = linearDistanceMm / linearVelocity
+angularSeconds = angularDistanceDeg / angularVelocity
+durationSeconds = max(linearSeconds, angularSeconds)
+```
+
+这至少能避免旋转轴运动被零时长吞掉。
+
+### 5.4 G93 inverse time
+
+LinuxCNC impeller 程序包含：
+
+```text
+G93
+...
+G1 ... F159
+```
+
+G93 的 F 不是 units/min，而是 inverse time。第一阶段有两种策略：
+
+```text
+方案 A：先检测 G93，明确标注 unsupported，RUN gate 阻止真实 feed mode 运行。
+方案 B：实现基础 inverse-time：duration_minutes = 1 / F，duration_seconds = 60 / F。
+```
+
+推荐：
+
+```text
+第一阶段实现方案 B。
+```
+
+原因：
+
+```text
+1. test_linuxcnc_source/impeller-7bl-xyzac.ngc 使用 G93。
+2. 如果不支持 G93，就无法验证用户当前指定测试文件的真实进给语义。
+3. 对 inverse-time，F 直接定义该运动块完成时间，适合第一阶段验证。
+```
+
+需要在 interpreter motion event 中增加：
+
+```js
+feedMode: "inverse-time" | "units-per-minute"
+```
+
+或至少在 timing 阶段通过 source line 扫描维护 G93/G94 模态。
+
+## 6. 代码修改落点
+
+### 6.1 `linuxcnc-interpreter-runtime.js`
+
+新增：
+
+```text
+feedModeBySourceLine(programText)
+```
+
+识别：
+
+```text
+G93 => inverse-time
+G94 => units-per-minute
+```
+
+motion event 增加：
+
+```js
+feedMode: activeFeedMode
+```
+
+### 6.2 `execution-timing.js`
+
+修改 `buildTimingSegment(...)`：
+
+```text
+if event.feedMode === "inverse-time":
+    durationSeconds = 60 / feedRate
+    velocityMmPerMin = linearDistanceMm / durationSeconds * 60
+else:
+    保持 G94 units/min 逻辑
+```
+
+注意：
+
+```text
+1. G93 中 F 必须大于 0。
+2. G93 中如果缺 F，应保留上一个 modal F 或报错，按 LinuxCNC 语义确认。
+3. velocity 仍要可被 INI max velocity 限制还是忠实 inverse-time，需要明确。第一阶段建议记录 requested 与 capped 两个值。
+```
+
+### 6.3 `store.js`
+
+在 `initializeTaskHalSession` 后或 `RUN_INTERPRETER_PROGRAM` 完成后，把当前 `programExecution.motion` 与 `programExecutionTiming.segments` 传给 task/HAL runtime：
+
+```js
+await state.taskHalRuntime.loadProgramMotionPlan({
+  programPath: session.programPath,
+  motion: state.programExecution.motion,
+  timing: state.programExecutionTiming,
+  linearUnits: state.profile.traj.linearUnits,
+});
+```
+
+需要保证：
+
+```text
+1. LOAD_LINUXCNC_GCODE_SOURCE 后 interpreter 已完成。
+2. task/HAL openProgram 的 programPath 与 motion plan programPath 一致。
+3. 如果 motion plan 不存在，RUN gate 应阻止“真实进给速度 RUN”，不能悄悄回退 velocity=60。
+```
+
+### 6.4 `linuxcnc-task-hal.js`
+
+新增 SDK 方法：
+
+```js
+loadProgramMotionPlan(plan) {
+  const rc = callWithJson(mod, "lctask_load_program_motion_plan_json", plan);
+  if (rc !== 0) throw new Error(...);
+}
+```
+
+### 6.5 `linuxcnc_task_hal_wasm.hh`
+
+新增声明：
+
+```cpp
+int lctask_load_program_motion_plan_json(const char *plan_json);
+```
+
+### 6.6 `linuxcnc_task_hal_wasm.cpp`
+
+新增：
+
+```text
+1. MotionSegment 数据结构。
+2. 简单 JSON plan parser，或复用现有轻量 json_number_after 风格解析数组。
+3. lctask_load_program_motion_plan_json。
+4. lctask_run_cycles 按 elapsed time 找 segment。
+5. 删除或隔离 fixed velocity=60 的 fallback。
+```
+
+要求：
+
+```text
+fixed velocity=60 只能作为 explicit fixture fallback。
+真实 RUN 路径不允许使用它。
+```
+
+## 7. 测试计划
+
+### 7.1 Node 单元测试：F 值改变 duration
+
+新增测试：
+
+```text
+web-rtcp-5axis-sim-plan/tests/node/verify_feed_rate_execution_timing.mjs
+```
+
+用例：
+
+```gcode
+G90 G94
+G1 X10 F60
+G1 X20 F600
+M2
+```
+
+期望：
+
+```text
+第一段 10mm @ 60mm/min => 10s。
+第二段 10mm @ 600mm/min => 1s。
+duration ratio ≈ 10:1。
+```
+
+### 7.2 Node 单元测试：G93 inverse time
+
+用例：
+
+```gcode
+G90 G93
+G1 X10 F2
+G1 X20 F10
+M2
+```
+
+期望：
+
+```text
+F2 => 60/2 = 30s。
+F10 => 60/10 = 6s。
+```
+
+### 7.3 task/HAL runtime 测试：速度不固定
+
+新增或扩展：
+
+```text
+web-rtcp-5axis-sim-plan/tests/node/verify_run_feedback_loop.mjs
+```
+
+断言：
+
+```text
+1. RUN feedback currentVelocityMmPerMin 不等于固定 3600。
+2. 不同 F 段采样到不同 requested/current velocity。
+3. activeLine 不再每 task cycle 固定递增一行。
+4. 慢速段停留采样数 > 快速段。
+```
+
+### 7.4 浏览器证据测试
+
+扩展：
+
+```text
+qa/web-rtcp-5axis-site-test/capture-test-linuxcnc-source-run.mjs
+```
+
+新增报告字段：
+
+```text
+feedMode
+feedRate
+segmentDurationSeconds
+segmentProgress
+requestedVelocityMmPerMin
+currentVelocityMmPerMin
+```
+
+报告验收：
+
+```text
+1. impeller G93 行显示 inverse-time。
+2. 采样 velocity 随当前 segment 变化。
+3. 当前行停留时间与 F 值/段时长一致。
+4. Word 报告中列出 F、feedMode、duration、velocity 的采样表。
+```
+
+## 8. 验收标准
+
+修复完成必须通过：
+
+```bash
+node web-rtcp-5axis-sim-plan/tests/node/verify_feed_rate_execution_timing.mjs
+node web-rtcp-5axis-sim-plan/tests/node/verify_run_feedback_loop.mjs
+node web-rtcp-5axis-sim-plan/tests/node/verify_linear_unit_conversion.mjs
+npm --prefix web-rtcp-5axis-sim-plan/app run build
+npm --prefix web-rtcp-5axis-sim-plan/app run smoke:node
+node qa/web-rtcp-5axis-site-test/capture-test-linuxcnc-source-run.mjs
+```
+
+并满足：
+
+```text
+1. 不再出现所有 RUN 样本 velocity=3600 的固定速度现象。
+2. C++ task/HAL RUN 主路径不再写死 velocity=60。
+3. G94 F60/F600 用例体现 10:1 段时长差异。
+4. G93 F2/F10 用例体现 5:1 段时长差异。
+5. test_linuxcnc_source/impeller-7bl-xyzac.ngc 的 RUN 报告包含 feedMode/feedRate/duration 证据。
+6. STOP/ABORT/STEP 现有测试不回退。
+```
+
+## 9. 风险与注意事项
+
+### 9.1 不要伪造 LinuxCNC 语义
+
+如果还没有完整 planner，就必须在状态中明确：
+
+```text
+semanticBoundary = feed_timed_canonical_motion_runtime
+```
+
+不要标称为真实 LinuxCNC planner。
+
+### 9.2 不要把 estimate 当作硬件实时
+
+第一阶段可以做到：
+
+```text
+canonical motion + feed mode + timing driven browser simulation
+```
+
+不能声称：
+
+```text
+hardware realtime LinuxCNC execution
+```
+
+### 9.3 G93 是当前 impeller 文件的关键
+
+`test_linuxcnc_source/impeller-7bl-xyzac.ngc` 开头有：
+
+```gcode
+M428 ;TCP:xyzac
+G93
+S600 M3
+```
+
+因此如果不处理 G93，针对该文件的“真实 F 速度”验证仍然不完整。
+
+## 10. 建议实施顺序
+
+```text
+1. 给 interpreter motion event 增加 feedMode。
+2. 给 execution-timing.js 增加 G93 duration。
+3. 写 verify_feed_rate_execution_timing.mjs，先证明 timing 正确。
+4. 给 task/HAL SDK/WASM 增加 loadProgramMotionPlan。
+5. 改 lctask_run_cycles，按 elapsed time 和 segment progress 推进。
+6. 改 store，把 motion plan 注入 task/HAL session。
+7. 扩展 verify_run_feedback_loop，证明 velocity 不固定、慢段停留更久。
+8. 扩展浏览器 RUN 报告，输出 feedMode/feedRate/duration/progress。
+9. 重跑 build、smoke、浏览器报告。
+10. 更新 working_run 和 gptlog-process。
+```

+## 3. INI definition contract
+
+`RUN` 只能基于一个完整、可验证的 LinuxCNC INI 上下文启动。INI 不是展示信息，而是机床契约来源。`parseLinuxCncIni()` 和 `applyIniConfigToProfile()` 必须把下面字段转成结构化状态，RUN gate 只读取结构化状态，不在 RUN action 中重新猜测字符串。
+
+### 3.1 必须存在的 INI sections
+
+当前五轴 `xyzac-trt` / `xyzbc-trt` profile 至少要求这些 section：
+
+| section | 是否必填 | RUN gate 用途 |
+| --- | --- | --- |
+| `[EMC]` | 必填 | 识别 machine name，确认是 switchkins 五轴 profile |
+| `[DISPLAY]` | 必填 | 提供默认打开程序、程序目录、UI 坐标提示；不能作为运动学真值 |
+| `[RS274NGC]` | 必填 | 提供 remap、subroutine path、HAL pin vars、parameter file |
+| `[KINS]` | 必填 | 提供 kinematics module 和 joint 数，是 kinematics/runtime 匹配依据 |
+| `[HAL]` | 必填 | 提供 HAL 文件、HALUI、POSTGUI_HALFILE、switchkins HALCMD |
+| `[HALUI]` | 必填 | 提供 M428/M429/M430 operator command 顺序和语义提示 |

+| `[AXIS_*]` | 必填 | 提供各坐标轴 limit/velocity/acceleration |
+| `[JOINT_*]` | 必填 | 提供 joint 类型、home、limit、home sequence |
+
+不满足这些 section 时，INI readiness 必须是 not ready，RUN 必须阻断。

+2. PROGRAM_PREFIX 用于解析 machine-file staging 的相对路径。
+3. GEOMETRY/JOG_AXES 用于 UI 呈现，不得覆盖 [TRAJ] COORDINATES。

+
+`xyzbc-trt` 的输出必须只在 profileId、machineName、coordinates、kinematics module、parameter/tool table、rotary axis B/C 等字段上变化，不能沿用 xyzac 的 A/C axis contract。
+
+### 3.4 INI contract 失败时的阻断
+
+这些情况必须让 `state.iniConfigReadiness.ready=false`，并阻断 RUN：
+
+```text
+缺少 [EMC] MACHINE。
+缺少 [TRAJ] COORDINATES。
+COORDINATES 不是 XYZAC 或 XYZBC。
+[KINS] KINEMATICS 不是 xyzac-trt-kins 或 xyzbc-trt-kins。
+[KINS] JOINTS 不是 5。
+缺少 M428/M429/M430 remap。
+HAL_PIN_VARS 不是 1。
+缺少 motion.analog-out-03 => motion.switchkins-type HALCMD。
+缺少 [EMCMOT] SERVO_PERIOD。
+缺少 [TASK] CYCLE_TIME。
+缺少 TOOL_TABLE。
+axis section 与 COORDINATES 不一致。
+joint section 数量与 [KINS] JOINTS 不一致。
+xyzac INI 指向 xyzbc tool table/parameter file，或反向混用。
+```
+
+阻断消息建议：
+
+```text
+run blocked: LinuxCNC INI contract invalid
+run blocked: INI missing required section [KINS]
+run blocked: INI coordinates do not match selected profile
+run blocked: INI switchkins remap incomplete
+run blocked: INI HAL switchkins signal missing
+run blocked: INI joint/axis contract mismatch
+```
+
+### 3.5 与 RUN gate 的关系
+
+INI contract 通过只是 RUN 的第一层 gate。RUN 仍必须继续检查：
+
+```text
+1. kinematics WASM 已按 INI [KINS] moduleId 加载。
+2. machine files 已按同一个 INI stage。
+3. task/HAL runtime 已按同一个 INI/session 初始化。
+4. selected G-code 已通过 task plan open 打开。
+5. task status 的 opened file 与 selected staged G-code 一致。
+6. machine ON、AUTO、homed/no_force_homing 满足。
+```
+
+所以不能把 `parseLinuxCncIni().validation.ready=true` 等同于 `RUN` ready。

+# 04 RUN status loop 完成记录与下一步建议
+
+生成时间：2026-06-22
+
+## 1. 本轮完成范围
+
+本轮完成 `03-run-step1-preconditions-complete-next-steps.md` 建议中的连续 feedback 工作，但命名从 `pump` 调整为更明确的：
+
+```text
+taskHalStatusLoop
+```
+
+这里的 loop 不生成 CNC 状态，不解析 G-code，也不自增行号。它只负责在 `RUN` 之后持续调度：
+
+```text
+taskHalRuntime.runCycles(...)
+taskHalRuntime.readStatus()
+dispatch TASK_HAL_STATUS_APPLIED
+```
+
+`activeLine`、`axisPose`、`currentVelocity`、`switchkinsType`、DRO 和 runtime feedback 仍来自同一个 task/HAL/motion status snapshot。
+
+## 2. 已完成改动
+
+### 2.1 store 增加 taskHalStatusLoop
+
+更新：
+
+```text
+app/src/state/store.js
+```
+
+新增状态：
+
+```text
+taskHalStatusLoop:
+  active
+  sequence
+  profileId
+  iniPath
+  kinematicsModuleId
+  tickCount
+  batchSize
+  intervalMs
+  taskPeriodNs
+  servoPeriodNs
+  lastStatusAt
+  lastError
+  stopReason
+```
+
+并新增：
+
+```text
+programRuntimeFeedbackHistory
+```
+
+最多保留 100 条 task/HAL/motion runtime feedback。
+
+### 2.2 RUN 改为连续读取 task/HAL status
+
+`RUN` 当前流程：
+
+```text
+1. validateRunPreconditions(..., requireTaskHalSession=false)
+2. 初始化或复用当前 machine-file task/HAL session
+3. validateRunPreconditions(..., requireTaskHalSession=true)
+4. 发送:
+   EMC_TASK_SET_STATE ON
+   EMC_TASK_SET_MODE AUTO
+   EMC_TASK_PLAN_RUN
+5. runCycles/readStatus 一次，应用首帧 status
+6. 如果 status 仍处于 READING，则启动 taskHalStatusLoop
+7. loop 持续 runCycles/readStatus，并通过 TASK_HAL_STATUS_APPLIED 更新 UI 状态
+```
+
+停止条件：
+
+```text
+interpState=IDLE 且 nextProgramLine >= openedLineCount -> complete
+interpState=PAUSED 或 motion.paused=true -> paused
+motion.aborted=true -> stopped
+```
+
+### 2.3 STOP / ABORT / PAUSE / RESUME / STEP
+
+更新行为：
+
+```text
+STOP/ABORT:
+  先停止 taskHalStatusLoop，再发送 EMC_TASK_ABORT，并读取一次 status。
+
+PAUSE:
+  先停止 taskHalStatusLoop，再发送 EMC_TASK_PLAN_PAUSE，并读取一次 paused status。
+
+RESUME:
+  发送 EMC_TASK_PLAN_RESUME，若 status 回到 READING，则重新启动 taskHalStatusLoop。
+
+STEP:
+  task/HAL runtime loaded 时不走 fixture playback。
+  改为明确 runCycles({ taskCycles: 1 }) 后 readStatus 一次。
+```
+
+### 2.4 新增验证
+
+新增：
+
+```text
+tests/node/verify_run_feedback_loop.mjs
+```
+
+覆盖：
+
+```text
+1. 加载 xyzac-trt INI。
+2. 加载 xyzac-trt kinematics WASM。
+3. 加载 task/HAL runtime。
+4. stage machine files。
+5. 打开 xyzac_switchkins_test_1.ngc。
+6. POWER/HOME/AUTO/RUN。
+7. 等待 programRuntimeFeedbackHistory 至少 3 条。
+8. 断言每条 feedback sourceMode 都是 linuxcnc-task-motion-hal-wasm。
+9. 断言 semanticBoundary 是 linuxcnc_task_motion_hal_wasm_simulation_runtime。
+10. 断言 taskCycle 和 servoCycle 单调递增。
+11. 断言 STOP 后 taskHalStatusLoop.active=false。
+```
+
+`app/package.json` 的 `smoke:node` 已加入：
+
+```text
+node ../tests/node/verify_run_feedback_loop.mjs
+```
+
+## 3. 已运行验证
+
+通过：
+
+```bash
+node tests/node/verify_run_feedback_loop.mjs
+node tests/node/verify_linuxcnc_task_hal_runtime.mjs
+node tests/node/verify_run_preconditions.mjs
+node tests/node/verify_rtcp_store.mjs
+npm --prefix app run build
+npm --prefix app run smoke:node

+rtcp_store_smoke=ok
+gmoccapy_static_build=ok
+```
+
+本轮 `npm --prefix app run smoke:node` 已完整通过，包括 native task/HAL audit。
+
+## 4. 当前 RUN 状态
+
+当前 `RUN` 已经从：
+
+```text
+发送 task command -> runCycles({ taskCycles: 5 }) -> readStatus() 一次
+```
+
+推进为：
+
+```text
+发送 task command
+-> runCycles/readStatus 首帧
+-> taskHalStatusLoop 持续 runCycles/readStatus
+-> TASK_HAL_STATUS_APPLIED 持续消费同一 task/HAL/motion status 链
+```
+
+重要边界仍保持：
+
+```text
+不引入 JS G-code parser。
+不在 UI 自增 activeLine。
+不在 UI 自造 axisPose。
+不把 canonical timing estimate 当作真实 task/HAL runtime。
+status 内容必须来自 task/HAL/motion runtime。
+```
+
+## 5. 下一步工作建议
+
+下一步建议做浏览器端证据采集：
+
+```text
+1. 扩展 qa/web-rtcp-5axis-site-test/capture-toolpath-preview-cases.mjs。
+2. 新增 07-run-preconditions-and-feedback case。
+3. 浏览器中执行 POWER/HOME/AUTO/RUN。
+4. 采集 t=0.2s / 0.5s / 1.0s / 2.0s state。
+5. 断言:
+   - taskHalStatusLoop.tickCount 增长
+   - programRuntimeFeedbackHistory 增长
+   - activeLine 等于 UI 高亮行
+   - DRO 读取 state.programRuntimeFeedback.axisPose
+   - RTCP canvas 状态与 state.rtcpState 一致
+6. 输出 JSON 和截图证据。
+```
+
+随后再考虑：
+
+```text
+1. 把 M428/M429 switchkins 状态变化纳入 RUN loop 浏览器断言。
+2. 增加 xyzbc-trt 的 RUN status loop 对称测试。
+3. 如果需要更接近真实 UI 实时性，再评估是否把 loop 下沉到 worker push status，而不是 store setTimeout polling。

+# 08 LinuxCNC 源程序测试资产
+
+生成时间：2026-06-22
+
+## 1. 选择结果
+
+本轮按用户要求，从 `/home/meswork/cnc_wams/linuxcnc` LinuxCNC 源程序中选定一组更适合项目测试的真实 RTCP/五轴资产：
+
+```text
+INI:
+/home/meswork/cnc_wams/linuxcnc/configs/sim/axis/vismach/5axis/table-rotary-tilting/xyzac-trt.ini
+
+G-code:
+/home/meswork/cnc_wams/linuxcnc/configs/sim/axis/vismach/5axis/table-rotary-tilting/demos/impeller-7bl-xyzac.ngc
+```
+
+已复制到 `working_run`：
+
+```text
+web-rtcp-5axis-sim-plan/working_run/test_linuxcnc_source/xyzac-trt.ini
+web-rtcp-5axis-sim-plan/working_run/test_linuxcnc_source/impeller-7bl-xyzac.ngc
+```
+
+已移除不合适的短程序副本：
+
+```text
+web-rtcp-5axis-sim-plan/working_run/test_linuxcnc_source/xyzac_switchkins_test_1.ngc
+```
+
+## 2. 选择原因
+
+选择 `xyzac-trt.ini` + `impeller-7bl-xyzac.ngc`，原因：
+
+```text
+1. INI 是 LinuxCNC 官方 5axis table-rotary-tilting 仿真配置。
+2. 坐标为 XYZAC，与当前项目默认 profile `xyzac-trt` 一致。
+3. KINEMATICS = xyzac-trt-kins sparm=identityfirst。
+4. 包含完整 M428/M429/M430 remap contract。
+5. 包含 HAL_PIN_VARS=1。
+6. 包含 motion.analog-out-03 => motion.switchkins-type HALCMD。
+7. G-code 以 M428 ;TCP:xyzac 进入 TCP/RTCP kinematics。
+8. G-code 使用 G93 inverse-time feed。
+9. G-code 包含大量 XYZAC 五轴联动段。
+10. G-code 共 4510 行，比短 switchkins test 程序更适合测试项目功能完整性。
+11. G-code 来自 /home/meswork/cnc_wams/linuxcnc 源程序，不是项目手写 fixture。
+```
+
+## 3. 源文件哈希
+
+当前副本与 `/home/meswork/cnc_wams/linuxcnc` 源文件逐字节一致：
+
+```text
+xyzac-trt.ini
+sha256=4b7fa6cb8d3e7031e769b3e0c779b586b67cfd45d715985f40d4ec23c662dc97

+```
+
+验证结果：
+
+```text
+ini_cmp=0
+ngc_cmp=0
+```
+
+## 4. 测试覆盖点
+
+这组资产覆盖：
+
+```text
+1. LinuxCNC INI definition contract。
+2. profile/INI 坐标一致性：XYZAC。
+3. kinematics module 一致性：xyzac-trt。
+4. RTCP/TCP kinematics：
+   M428 -> xyzac TCP
+5. inverse-time feed：
+   G93
+6. 长路径五轴联动：
+   XYZAC motion lines with A/C rotary axes
+7. machine-file staging。
+8. taskHalRuntime.openProgram(programPath)。
+9. RUN command sequence。
+10. taskHalStatusLoop feedback。
+11. UI activeLine/DRO/RTCP/runtime feedback same-snapshot 证据。
+12. 长路径 preview、执行轨迹、rapid/feed 与五轴姿态变化。
+```
+
+## 5. 已运行验证
+
+执行：
+
+```bash
+node web-rtcp-5axis-sim-plan/tests/node/verify_real_linuxcnc_5axis_program_cases.mjs

+# 09 单位换算与 Three.js 米单位场景完成记录
+
+生成时间：2026-06-22
+
+## 本轮目标
+
+解决英寸、毫米、米之间的单位换算问题，重点覆盖：
+
+- 实时轴值显示；
+- 刀具路径预览；
+- 刀具执行轨迹；
+- Three.js 绘图坐标统一使用米。
+
+## 完成情况矩阵
+
+| 项目 | 完成状态 | 代码落点 | 验证 |
+| --- | --- | --- | --- |
+| 公共线性单位换算 | 已完成 | `app/src/runtime/linear-units.js` | `verify_linear_unit_conversion.mjs` |
+| mm/inch/m 到米转换 | 已完成 | `linearValueToMeters()`、`axesToSceneMeters()` | `25.4mm == 1inch == 0.0254m` |
+| 执行计时距离归一到毫米 | 已完成 | `app/src/runtime/execution-timing.js` | inch 段长 `1 inch -> 25.4 mm` |
+| 执行计时进给归一到 mm/min | 已完成 | `app/src/runtime/execution-timing.js` | inch feed `1 inch/min -> 25.4 mm/min` |
+| G20/G21 程序单位解析 | 已完成 | `app/src/runtime/linuxcnc-interpreter-runtime.js` | G20 motion 标记 `inch`，G21 motion 标记 `mm` |
+| 刀具路径预览使用米 | 已完成 | `app/src/visualization/five-axis-scene.js` | motion axes 经 `axesToSceneMeters()` |
+| 刀具执行轨迹使用米 | 已完成 | `app/src/visualization/five-axis-scene.js` | timing samples 携带/继承 motion 单位 |
+| 当前刀位 marker 使用米 | 已完成 | `app/src/visualization/five-axis-scene.js` | runtime feedback linearUnits 参与转换 |
+| Three.js 机床参考模型使用米尺度 | 已完成 | `app/src/visualization/five-axis-scene.js` | 参考模型尺寸从任意倍率改为米尺度 |
+| 2D fallback 使用米尺度 | 已完成 | `app/src/visualization/five-axis-scene.js` | fallback scale 改为米坐标范围 |
+| 轴值实时显示 | 已确认边界 | `store.axisPose` / DRO | 保留机床/程序单位，不改成米 |
+
+## 关键设计结论
+
+实时轴值显示不应强制转换为米。DRO/axisPose 表示当前机床或程序坐标单位，应保留 LinuxCNC/INI/G-code 的语义；Three.js 预览层才统一转换为米。
+
+Three.js 场景现在通过 dataset 暴露：
+
+```text
+data-three-scene-units="m"
+data-three-linear-units="<mm|inch|m>"
+data-three-linear-unit-scale-to-meters="<factor>"
+```

+npm --prefix web-rtcp-5axis-sim-plan/app run build
+```
+
+结果均通过。
+
+## 后续工作
+
+1. 增加浏览器截图证据，确认米尺度 Three.js 画面在 desktop/mobile 下不空白、不偏移。
+2. 如果后续接入真实 task/motion HAL feedback，需要确认 feedback 坐标是否已经按 INI 单位输出，并继续填充 `programRuntimeFeedback.linearUnits`。
+3. 可继续补 G-code 中途 G20/G21 切换的多段浏览器端预览用例。

+
+生成时间：2026-06-22
+
+## 1. 本轮目标
+
+在 `05` 到 `09` 已完成 RUN 主链路、浏览器 RUN 证据和米单位场景的基础上，继续补齐 `07`、`09` 中列出的剩余可自动验证项。

+```
+
+### 步骤 4：补 RUN gate 细粒度断言
+
+测试落点：
+

 当前实现已经能显示 G-code 程序文本、当前行、高亮行、DRO、runtime feedback 和 task/HAL 状态。
 
-但按 `textbak` 接续文件的边界要求，当前 `RUN` 还不是连续的 task/HAL feedback 推送执行模型：
+`04` 完成后，当前 `RUN` 已从单次 task/HAL status 读取推进为连续 status loop：
 
 ```text
 RUN 点击后:
-1. UI 发送 EMC_TASK_SET_STATE / EMC_TASK_SET_MODE / EMC_TASK_PLAN_RUN；
-2. store 调用 taskHalRuntime.runCycles({ taskCycles: 5 })；
-3. 随后 readStatus() 一次；
-4. TASK_HAL_STATUS_APPLIED 将这一次 status 映射到 activeLine / axisPose / velocity / feedback；
-5. 没有看到 worker 主动持续 postMessage 推送 status；
-6. 如果没有再次调用 runCycles/readStatus，状态不会继续随真实时间推进。
+1. UI 确认 opened program、machine ON、AUTO、homed 后发送 EMC_TASK_SET_STATE / EMC_TASK_SET_MODE / EMC_TASK_PLAN_RUN；
+2. store 调用 taskHalRuntime.runCycles(...)；
+3. store 调用 taskHalRuntime.readStatus()；
+4. TASK_HAL_STATUS_APPLIED 将 task/HAL/motion status 映射到 activeLine / axisPose / velocity / feedback；
+5. taskHalStatusLoop 持续重复 runCycles/readStatus；
+6. programRuntimeFeedbackHistory 保留最近 100 条 task/HAL/motion feedback。
 ```
 
-因此，当前问题重点不是“前端是否需要定时器”，而是：
+该顺序与 LinuxCNC 源码中的 `halui.cc::sendProgramRun()`、`shcom.cc::sendProgramOpen/sendProgramRun()`、`emctaskmain.cc::EMC_TASK_PLAN_OPEN/RUN/PAUSE/RESUME` 对齐：RUN 不是前端播放，而是在已打开程序和可运行 task 状态下发送 `EMC_TASK_PLAN_RUN`，后续状态来自 task/motion/HAL feedback。
+
+当前仍需保持的边界是：
 
 ```text
-task/HAL runtime 是否能在 G-code 执行期间持续产出状态；
-UI/store 是否持续消费这些 LinuxCNC-owned 状态；
-轴值、当前行、速度、DTG、程序时间是否都来自同一条 task/HAL/motion feedback 链。
+taskHalStatusLoop 只负责调度 runCycles/readStatus；
+status 内容必须来自 task/HAL/motion runtime；
+UI/store 不自增 activeLine；
+UI/store 不自造 axisPose；
+浏览器端米尺度 desktop/mobile 截图证据已补齐；
+G20/G21 混合单位浏览器预览证据已补齐。
+working_run 已列出的必做接续项已全部复核通过，仅保留可选增强。
