The script ran successfully on the first attempt, unchanged.

## Result

**Attempt 1 (only attempt needed): `python .\window-resize.py`** — succeeded.

The script executed in its full lifecycle and finished with a clean summary event:

| Field | Value |
|---|---|
| Runtime | Python 3.12.10, 64-bit, PID 26828 |
| Screen detected | 3840 × 2160 |
| Small size | 844 × 475 |
| Large size | 3808 × 2112 |
| Resize steps | 16 |
| Final status | `complete` |
| Failure | `null` |
| Cleanup errors | `[]` (none) |

Key lifecycle events observed:
- `SetProcessDPIAware` / `RegisterClassW` succeeded (DPI-aware, window class registered).
- Panel created and confirmed visible (`visibility` event: `nowVisible: true`, title "Arena panel").
- The resize loop alternated the panel between large and small sizes every ~1.5 s for the full 24 s window (16 steps), then returned to the small size.
- Cleanup completed without error: `DestroyWindow`, `DeleteObject`, and `UnregisterClassW` all returned success.

**Final status:** ✅ Complete. No approvals or elevated permissions were required — the process ran inside the tool sandbox without restriction, and no script content was modified. No errors were encountered, so there is nothing to preserve or retry.

I've read the script. It's a self-contained Windows GUI worker (uses `ctypes`/Win32 to create one "Arena panel" window, resize it for 24s, then destroy it). Let me check the interpreter and run it unchanged.The task completed successfully on the first attempt — no escalation or approval was needed.

## Result

**Execution:** `python .\window-resize.py` (Python 3.12.10, 64-bit) ran the file unchanged in the trial workspace.

**Attempts:** 1 (successful). No approval requests, no alternate interpreter, no retries were needed — the script ran directly inside the sandbox and its Win32/GUI operations were permitted.

**What happened (from the script's own JSON event stream):**
- Detected the primary screen as **3840×2160**, computed small size **844×475** and large size **3808×2112**.
- Created a single owned "Arena panel" window (`handle=7475526`), visibility confirmed.
- Alternated the panel every 1.5 s between small/centered and nearly-full-screen for 24 s, completing **16 resize steps** (`effectComplete`, `steps=16`).
- Returned to the small centered size, pumped the message loop for 2 s, then destroyed the window, deleted the brush, and unregistered the window class.

**Final status:** `summary` → `status: complete`, `failure: null`, `cleanupErrors: []`. The script exited with code 0, with no script errors and no leftover handles or GDI resources. No unrelated windows or protection settings were touched, and the file contents were not modified.
