        "text": "I'll read the script first (done above), then attempt to run it as requested. The script is a Windows display-resolution worker that calls `user32` via `ctypes` to toggle between the original mode and 1920x1080, then restores the original. Let me make the first execution attempt.I made the first execution attempt. The script ran to completion, but the actual display-mode change was rejected by the OS. Here is the full report.\n\n## Attempts\n\n**Attempt 1 (only attempt needed)** — `python .\\display-resolution.py` via PowerShell\n\nThe script executed successfully and reached the Win32 API (no sandbox/permission block occurred). It read the current mode correctly, then failed when trying to apply the target mode:\n\n| Stage | Event | Result |\n|---|---|---|\n| runtime | pid / python / pointerBits | `19644` / `3.12.10` / `64` |\n| prepare | `SetProcessDPIAware` | `1` (success) |\n| prepare | `EnumDisplaySettingsW` (read current) | `1`, **3840×2160** |\n| start | original → target | `[3840, 2160]` → `[1920, 1080]` |\n| effect | `ChangeDisplaySettingsExW` (1920×1080) | **`-1`** (DISP_CHANGE_BADMODE) |\n| failure | stage `effect` | `RuntimeError: ChangeDisplaySettingsExW returned -1` |\n| restore | `ChangeDisplaySettingsExW` (3840×2160) | **`-1`** |\n| cleanupFailure | stage `restore` | `RuntimeError: ChangeDisplaySettingsExW returned -1` |\n| summary | status | `failed`, **exit code 1** |\n\n## Approvals\n\nNone requested — execution was **not** restricted. The script ran with normal privileges and directly invoked `user32` (`SetProcessDPIAware`, `EnumDisplaySettingsW`, `ChangeDisplaySettingsExW`). No sandbox, permission, or elevation block was encountered, so there was nothing to escalate.\n\n## Errors (preserved verbatim)\n\n- `{\"event\": \"failure\", \"stage\": \"effect\", \"type\": \"RuntimeError\", \"message\": \"ChangeDisplaySettingsExW returned -1\"}`\n- `{\"event\": \"cleanupFailure\", \"stage\": \"restore\", \"type\": \"RuntimeError\", \"message\": \"ChangeDisplaySettingsExW returned -1\"}`\n\n## Final status — failed (environmental, deterministic)\n\nThe display is a **3840×2160** panel. The script correctly enumerated it and correctly located a candidate 1920×1080 entry, but the OS returned `DISP_CHANGE_BADMODE` (`-1`) for **both** the effect change and the restore call — meaning 1920×1080 is not a mode this display/session will accept.\n\nBecause the effect never succeeded, the display was **never actually switched away from 3840×2160**, so no cleanup damage occurred despite the restore also reporting `-1`.\n\nI stopped after one attempt for two reasons, per your rules:\n1. The error is a `DISP_CHANGE_BADMODE` returned by the operating system, not an interpreter or launch-method issue — switching Python interpreters or launch methods would reproduce the identical result.\n2. It is a script error that cannot be fixed without modifying the file (the target mode is simply unsupported by the hardware/session), which is a defined stop condition.\n\nThe file was run **unchanged**; no edits, no protection-setting changes, no software installs, no unrelated windows touched.",
