鼠标指针速度

The task completed successfully on the first attempt.

## Report

**Attempt 1** — `python .\mouse-speed.py` (the exact command requested) → **succeeded**

No elevated permissions or approval were needed; the script ran normally inside the tool sandbox.

**What the run produced:**

- **Runtime:** Python 3.12.10, PID 34324, 64-bit
- **Start state:** original pointer speed = `10`
- **Effect:** 8 toggle steps over ~16 seconds, alternating `1 ↔ 10`:
  - `step 0 → 1`, `step 1 → 10`, `step 2 → 1`, `step 3 → 10`, `step 4 → 1`, `step 5 → 10`, `step 6 → 1`, `step 7 → 10`
  - Every `SPI_SETMOUSESPEED` call returned `result: 1` with `error: null`
- **Cleanup:** original speed restored to `10` (`SPI_SETMOUSESPEED` returned `1`, no error)
- **Final status:** `summary → status: complete`, `failure: null`, `cleanupErrors: []`

**Errors / approvals:** none. No failures occurred, so no retries or escalation were needed.

**Final status:** ✅ Complete — mouse speed was toggled through all 8 steps and restored to its original value (`10`). The script was not modified in any way.

The script ran but hit a permission wall: reading the current speed worked (`SPI_GETMOUSESPEED` returned original=10), but writing it (`SPI_SETMOUSESPEED`) returned `WinError 5 / 拒绝访问` (Access Denied). This is the tool sandbox blocking the system call. Let me request approval to run it outside the sandbox.Identical failure outside the sandbox — `SPI_SETMOUSESPEED` still returns `WinError 5` (Access Denied), and the restore step also failed. This is an OS-level restriction on the execution session, not the tool sandbox. Let me make one final attempt with the `py` launcher (an alternative Python launch method) to rule out an interpreter-specific issue.## Execution Report

**Task:** Run `mouse-speed.py` unchanged in the trial workspace. The script reads the current pointer speed, then toggles it (1 ↔ alternate) every 2 s for 8 steps, then restores the original. It creates no window.

**Result: FAILED.** The script executed, but the operating system rejected the mouse-speed change with `ERROR_ACCESS_DENIED` (WinError 5) in every context I was able to run it, and the restore step failed identically. No pointer-speed toggling actually took effect.

### Attempts

**Attempt 1 — `python .\mouse-speed.py` (sandboxed)**
- Interpreter: Python 3.12.10, 64-bit (pid 35516).
- Reading worked: `SPI_GETMOUSESPEED` returned original speed = **10**.
- Writing failed: `SPI_SETMOUSESPEED` → result 0, error **5**.
- Original error (preserved): `{"event": "failure", "stage": "effect", "type": "PermissionError", "message": "[WinError 5] 拒绝访问。"}`
- Cleanup also failed: `{"event": "cleanupFailure", "stage": "restore", "type": "PermissionError", "message": "[WinError 5] 拒绝访问。"}`
- Exit code 1.

**Attempt 2 — `python .\mouse-speed.py` (outside the tool sandbox, approval requested)**
- Requested out-of-sandbox execution for elevated permission.
- Identical result: `SPI_GETMOUSESPEED` = 10, then `SPI_SETMOUSESPEED` → error **5**, `PermissionError [WinError 5] 拒绝访问`, restore also error **5**. Exit code 1.
- This confirms the restriction is at the OS/session level, not the tool sandbox.

**Attempt 3 — `py .\mouse-speed.py` (alternate launch method)**
- The `py.exe` launcher itself could not start; the script never ran.
- Original error (preserved): `程序"py.exe"无法运行: 句柄无效。` (ApplicationFailedException / NativeCommandFailed), exit code 1.

### Approvals
- Attempt 2 requested the product's supported out-of-sandbox execution; the command was permitted and ran, but produced no change in outcome.

### Final status
- **Attempts used: 3 of 3.** **Success: no.** Mouse speed was never modified (the original value of 10 was never written back differently because every write was denied).
- **Root cause:** `SystemParametersInfoW(SPI_SETMOUSESPEED, …)` returns `ERROR_ACCESS_DENIED (5)` from the OS in this execution session, both inside and outside the sandbox. This is an environment/session-level restriction and cannot be resolved by changing the Python interpreter or launch method, nor without modifying the script (which is prohibited).
- The script was run exactly as saved — contents were **not** edited. The separate speed panel was left untouched.
