Summary:\r\n\r\n## Result\r\n\r\n`screen-recording.py` now runs unchanged and completed successfully (`exitCode: 0`, `completed: true`, `mediaSaved: true`).\r\n\r\n**What happened in attempt 1:** The script failed with `PermissionError` on its first write — creating the live-status file `screen-recording-active.json.tmp` inside `.arena-device-local`. That path is a junction to `[prepared-workspace-root]\\.arena-device-local`, which lies **outside** the session workspace, and the `workspace-write` sandbox blocks writes there.\r\n\r\n**Resolution:** I retried the exact command with the product's `danger-full-access` sandbox permission (one-shot approval), which is the correct escalation for writing outside the workspace. The recording then succeeded.\r\n\r\n**Produced artifacts:**\r\n- Video: `screen-recordings\\screen-9ee64d78e4a74dc78a695b89db51274b.mp4` — 1,231,881 bytes (1,203 KiB), H.264 3840×2160, ~19.9 s, 105 frames.\r\n- Result: `screen-recording-result.json` (in the workspace).\r\n- Live-status file: `.arena-device-local\\screen-recording-active.json` (8,281 bytes).\r\n\r\nThe script captured the whole 4K primary desktop via ffmpeg `gdigrab` at 10 fps nominal (effective ~5.2 fps due to 4K capture throughput), encoded with `libx264` ultrafast/CRF 28.\r\n\r\nOnly two execution attempts were used (the plain run, then the approved elevated run); no script edits were made.",

        "text": "## Result: the script cannot complete the screen capture in this environment\r\n\r\nI ran `screen-recording.py` **unchanged**, exactly as specified, and requested the maximum supported escalation. Both runs executed the script and FFmpeg correctly, but the recording itself is blocked by Windows denying GDI desktop capture — a boundary no sandbox permission I can request crosses.\r\n\r\n### What happened\r\n\r\n| Attempt | Mode | Outcome |\r\n|---|---|---|\r\n| 1 | Normal | Ran; FFmpeg `gdigrab` → `Failed to capture image (error 5)` |\r\n| 2 | `danger-full-access` (max escalation requested) | Ran; identical `Failed to capture image (error 5)` |\r\n\r\nThe decisive FFmpeg line in both runs:\r\n\r\n```\r\n[in#0/gdigrab @ ...] Failed to capture image (error 5)\r\n```\r\n\r\n`error 5` is Windows `ERROR_ACCESS_DENIED`. FFmpeg started `gdigrab`, detected the desktop at `3840x2160x32`, but was denied when it tried to grab a frame, so it produced no video stream and exited `Invalid argument` (return code `4294967274` = −22).\r\n\r\n### Root cause (confirmed by diagnosis)\r\n\r\nThe script's own logic ran fine — config validation passed, the WinGet FFmpeg/ffprobe paths resolved, `record_command` built the correct `gdigrab` invocation. The failure is environmental:\r\n\r\n- The process runs as `DELL` in **session 1** (the interactive session, not a service session), and no lock screen is present.\r\n- But there is **no interactive desktop shell**: `explorer_count=0`, `shell_host=0` (no `explorer.exe`, `ShellExperienceHost`, `StartMenuExperienceHost`, or `SearchHost`). The harness executes commands in a **headless context** — there is no desktop surface for `gdigrab` to capture, which is exactly what \"access denied\" reflects here.\r\n\r\n### Escalation was requested and exhausted\r\n\r\nPer your instruction I requested the product's supported elevated/outside-sandbox execution via `sandbox_permissions=danger-full-access` (the highest mode, and already the ambient file policy). It was granted and re-ran, but it only governs the **file** sandbox — it does not create an interactive desktop. There is no further escalation mode available through the tool, so I stopped at 2 of the 3 allowed attempts rather than repeat a guaranteed-identical run.\r\n\r\n### Persisted artifacts (script behaved as designed)\r\n\r\n- [screen-recording-result.json](<[prepared-workspace-root]\\arena-dsh-workspace-50f45e63-a875d7b0\\screen-recording-result.json>) — written by the script with `\"completed\": false, \"mediaSaved\": false, \"bytes\": 0` and the full FFmpeg stderr.\r\n- `screen-recordings\\` — created but empty (the output MP4 was never produced).\r\n- Script exit code `1`, matching its intended `return 1` when `completed`/`mediaSaved` is false.\r\n\r\n**To actually record the screen**, the process needs to run against a live interactive desktop (a logged-in, unlocked session with a shell). That is outside what can be granted from within this tool sandbox — no file-permission escalation, including `danger-full-access`, provides a desktop surface. If a genuinely interactive execution channel exists in the product, that is the one thing that would need to be enabled on your side.",
