 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。
+
+### 五、2026-06-18 Macro Load Blocked Fixture Lock
+
+本批按上一节建议先评估 `gscreen/silverdragon/macros/tool_sensor.ngc`。结论是不能直接
+作为 positive macro/load fixture 推进：当前 generated boundary evidence 显示 owning
+machine file `gscreen/silverdragon/silverdragon.ini` 在 vendored manifest 中不可用，且该
+family 涉及 Python UI/process 边界风险。为避免 virtual HAL 误解锁 Python UI 或
+Python remap family，本批新增 negative fixture gate。
+
+新增实质能力：
+
+- 新增 `VIRTUAL_HAL_SIM_CONFIG_MACRO_LOAD_BLOCKED_FIXTURES`；
+- `createVirtualHalSimConfigMacroLoadFixtureReport()` 新增：
+  - `blockedRows`；
+  - `blockedFixturePromotionViolations`；
+  - summary row：`blocked-fixture-lock`；
+- 首批 blocked fixture：
+  - `silverdragon-tool-sensor-python-ui-boundary`：
+    - `fixturePath` 为
+      `linuxcnc/configs/sim/gscreen/silverdragon/macros/tool_sensor.ngc`；
+    - `owningIniPath` 为
+      `linuxcnc/configs/sim/gscreen/silverdragon/silverdragon.ini`；
+    - `blockedKind` 为 `PYTHON-UI-PROCESS`；
+    - 必须 `excludedFromPositiveFixtures === true`；
+  - `gmoccapy-on-abort-python-remap-boundary`：
+    - `fixturePath` 为
+      `linuxcnc/configs/sim/gmoccapy/macros/on_abort.ngc`；
+    - `owningIniPath` 为 `linuxcnc/configs/sim/gmoccapy/6_axis.ini`；
+    - `blockedKind` 为 `L4-PYTHON-REMAP`；
+    - 必须 `excludedFromPositiveFixtures === true`；
+- release diagnostics validation 新增 required negative evidence：
+  - `blockedFixturePromotionViolations.length === 0`；
+  - SilverDragon `tool_sensor.ngc` 与 gmoccapy `on_abort.ngc` 必须存在于
+    `blockedRows`；
+  - 两者不能出现在 positive macro/load fixture rows；
+- real simulation smoke 与 SDK smoke 同步验证 blocked fixture lock；
+- coverage matrix 对 `gscreen/silverdragon/macros/tool_sensor.ngc` 注释更新为 blocked
+  negative fixture；
+- promotion analysis 文档新增 Macro/Load Blocked Fixture Lock 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；
+- 本批没有把 SilverDragon、gmoccapy 或任何 Python UI / Python remap family 作为
+  virtual HAL positive fixture 推进；
+- 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、native
+  HAL module ABI、Python UI process emulation 或 Python remap runtime；
+- `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. 为 macro/load fixture report 增加 UI-family candidate audit，将
+   `gscreen/industrial_lathe_wear/toolchange.ngc` 与
+   `qtvcp_screens/industrial_lathe_wear/toolchange.ngc` 先作为 audit rows 评估。
+2. 只有 owning INI、machine files、tool table、UI/process declaration 都有
+   LinuxCNC source evidence，且不需要 Python UI process emulation 时，才允许转为
+   positive non-main fixture。
+3. 如证据仍不完整，继续扩展 blocked fixture lock，不降低 inventory baseline。

+## 2026-06-18 Macro/Load Blocked Fixture Lock
+
+The macro/load report now also carries a blocked-fixture lock. This is a
+negative evidence gate: it proves selected macro/load paths are not included in
+positive virtual HAL fixtures when their owner boundary is still unavailable or
+outside the virtual HAL scope.
+
+The first blocked fixture rows are:
+
+- `gscreen/silverdragon/macros/tool_sensor.ngc`
+- `gmoccapy/macros/on_abort.ngc`
+
+`tool_sensor.ngc` is intentionally not promoted because the owning
+`gscreen/silverdragon/silverdragon.ini` machine file is not available in the
+vendored manifest, and promoting it would require a Python UI/process boundary
+proof rather than virtual HAL diagnostics alone. `gmoccapy/macros/on_abort.ngc`
+remains locked behind `L4-PYTHON-REMAP` and LinuxCNC-owned Python
+remap/prolog/epilog runtime proof.
+
+Release diagnostics validation now requires
+`blockedFixturePromotionViolations` to stay empty and requires both blocked
+rows to be excluded from positive macro/load fixtures. This prevents virtual
+HAL from accidentally unlocking Python UI or Python remap families.
+
+The next practical slice is to add a machine-readable candidate audit for other
+UI-family macro/load rows before promoting any new positive fixture.
