+### 四、2026-06-18 Macro Load Non-Main Fixture Evidence
+
+本批接续 Non-Qt promotion evidence，完成 macro/load non-main fixture report 首批闭环。
+
+新增实质能力：
+
+- 新增 `VIRTUAL_HAL_SIM_CONFIG_MACRO_LOAD_FIXTURES`；
+- 新增 `createVirtualHalSimConfigMacroLoadFixtureReport()`：
+  - 输出 `linuxcnc-wasm-virtual-hal-sim-config-macro-load-fixture-report`；
+  - 显式输出 `inventoryBaselineUnchanged === true`；
+  - 每个 row 必须 `nonMainFixture === true`；
+  - 每个 row 的 `targetBrowserEvidence` 必须为
+    `non-main-fixture-diagnostics`；
+  - `standaloneMainViolations` 必须为空；
+  - source manifest 只校验 LinuxCNC source evidence，不把 declared-only fixture path
+    误当成 manifest 文件；
+- 首批 fixture：
+  - `rose-engine-rcone-macro-load`：
+    - `fixturePath` 为
+      `linuxcnc/configs/sim/axis/rose_engine/rcone.ngc`；
+    - source evidence 包含 `rose_engine.ini`、`rcone.ngc`、`rcone_demo.ngc`；
+    - 与 `rcone_demo.ngc` 配对作为 rose engine non-main macro/load evidence；
+  - `external-offsets-queuebuster-macro-load`：
+    - `fixturePath` 为
+      `linuxcnc/configs/sim/axis/external_offsets/queuebuster.ngc`；
+    - source evidence 包含 `eoffsets.ini` 与 `eoffsets.ngc`；
+    - `declaredOnly === true`，通过 `eoffsets.ini` 的 `NGCGUI_SUBFILE` 声明保留
+      fixture path，不声明它是 standalone browser main program；
+- `createLinuxCncVirtualHalRuntime()` 新增：
+  - `getSimConfigMacroLoadFixtureReport()`；
+- SDK index、SDK README、browser simulation re-export 同步导出新常量和新 report API；
+- real simulation diagnostics artifact 新增：
+  - `virtualHalSimConfigMacroLoadFixtures`；
+  - browser API `getVirtualHalSimConfigMacroLoadFixtureReport()`；
+- OPFS/session virtual HAL payload 新增：
+  - `simConfigPromotionCandidates`；
+  - `simConfigMacroLoadFixtures`；
+  - saved-session diagnostics nested artifact 同步携带两类 evidence；
+- release diagnostics validation 新增 required evidence：
+  - `hasMacroLoadFixtures`；
+  - `macroLoadFixturesReady`；
+  - validation row：`sim-config-macro-load-fixtures`；
+  - 缺少 `virtualHalSimConfigMacroLoadFixtures` 时 release diagnostics validation 不再 ready；
+- coverage matrix 对 `axis/rose_engine/rcone.ngc` 与
+  `axis/external_offsets/queuebuster.ngc` 注释更新为 non-main fixture diagnostics evidence；
+- promotion analysis 文档新增 Macro/Load Non-Main Fixture Evidence 小节。
+
+语义边界：
+
+- 本批没有降低 inventory skip count；
+- 当前 baseline 仍是 `executed=28`、`passed=28`、`skipped=131`、
+  `unexpected_fail=0`；
+- 本批没有新增 G-code/interpreter/planner/kinematics/remap 语义；
+- macro/load fixture evidence 只证明 LinuxCNC-owned source/config declaration 与
+  virtual HAL diagnostics readiness；
+- `queuebuster.ngc` 只作为 `eoffsets.ini` 的 `NGCGUI_SUBFILE` declared-only fixture path
+  记录，不作为 manifest-backed standalone file，也不作为 browser main program 执行；
+- virtual HAL 已满足 Web 方式数控系统仿真系统，并在仿真范围内替代 LinuxCNC
+  realtime HAL、`halcmd`、motion controller；
+- virtual HAL 仍不提供 Linux kernel hard-realtime ABI、外部硬件驱动 ABI 或 native
+  HAL module ABI；
+- `L4-PYTHON-REMAP`、`L4-TOOL-DB`、`L4-USER-M-PROCESS`、`UPSTREAM-DEMO` 仍保持
+  locked；
+- G-code/interpreter/planner/canonical motion 语义仍来自 LinuxCNC-backed WASM。
+
+下一步工作建议：
+
+1. 扩展 macro/load fixture report 到一个 UI-family non-main 案例，优先评估
+   `gscreen/silverdragon/macros/tool_sensor.ngc`。
+2. 推进前必须确认 owning machine files、UI process declaration 和 source evidence，
+   不能把 Python UI process emulation 纳入 virtual HAL 范围。
+3. 如 UI-family 边界不清晰，先增加 negative fixture gate：证明
+   `L4-PYTHON-REMAP` / Python UI process 相关 macro/load 不会被 macro/load fixture
+   report 误解锁。

+## 2026-06-18 Macro/Load Non-Main Fixture Evidence
+
+The virtual HAL diagnostics evidence now includes an explicit macro/load
+fixture report:
+
+- `VIRTUAL_HAL_SIM_CONFIG_MACRO_LOAD_FIXTURES`
+- `createVirtualHalSimConfigMacroLoadFixtureReport()`
+
+The first required non-main fixtures are:
+
+- `axis/rose_engine/rcone.ngc`
+- `axis/external_offsets/queuebuster.ngc`
+
+The rose-engine fixture is paired with `rcone_demo.ngc` and keeps `rcone.ngc`
+as a non-main macro/load asset. The external-offsets fixture records
+`queuebuster.ngc` as a declared `NGCGUI_SUBFILE` through `eoffsets.ini`; the
+fixture path is preserved for diagnostics, while the manifest-backed source
+evidence is the owning INI and paired LinuxCNC program source. This avoids
+pretending that `queuebuster.ngc` is a standalone browser main program.
+
+Release diagnostics validation now requires
+`virtualHalSimConfigMacroLoadFixtures` to be present and ready. The report must
+keep `inventoryBaselineUnchanged === true`, every row must have
+`nonMainFixture === true`, and `standaloneMainViolations` must stay empty.
+
+The next practical slice is to extend this report with one more non-main family
+such as `gscreen/silverdragon/macros/tool_sensor.ngc`, after proving the owning
+machine files and UI/process boundary do not cross into Python UI emulation.
