That points to the tool sandbox restricting cross-process handle access. Let me retry the same unchanged script with approval to run outside the sandbox.Same `WinError 5` even outside the sandbox — so the block isn't the tool sandbox. The `OpenProcess` error is `5` (Access Denied), which means PID 59472 is alive but owned by a context the current account can't open with `PROCESS_DUP_HANDLE`. Let me inspect the process identity and current token.I've completed the execution attempts and diagnosed the root cause. Here's the full report.\r\n\r\n## Attempts made\r\n\r\n**Attempt 1 — sandboxed run**\r\n`python .\\process-handle-duplicate.py` (Python 3.12.10), unchanged, as instructed. The script validated `target.json`, wrote its registration, and **received host safety admission** (`\"event\": \"admitted\"`), then reached the effect stage and failed:\r\n\r\n```\r\n{\"event\": \"nativeResult\", \"api\": \"OpenProcess\", \"result\": 0, \"error\": 5, \"pid\": 59472, \"access\": 4160}\r\n{\"event\": \"failure\", \"stage\": \"effect\", \"type\": \"PermissionError\", \"message\": \"[WinError 5] 拒绝访问。\"}\r\n{\"event\": \"summary\", \"status\": \"failed\", ...}\r\nExit Code: 1\r\n```\r\n\r\n**Attempt 2 — elevated / outside the tool sandbox (approval requested)**\r\nRe-ran the same unchanged file with the product's supported \"run outside sandbox\" approval. The host admitted it again, but the effect failed identically with `OpenProcess → WinError 5 (Access Denied)` on PID 59472.\r\n\r\n**Attempt 3** — not performed. The root cause below is independent of interpreter choice; any child Python process inherits the same token, so a different interpreter could not change the outcome.\r\n\r\n## Approvals\r\n- Requested and obtained execution outside the tool sandbox for attempt 2. It did **not** change the effective privilege level.\r\n\r\n## Root cause (diagnosed)\r\nThe agent process is running under a heavily restricted token:\r\n\r\n- `BUILTIN\\Administrators` → **deny-only** (grants no admin rights)\r\n- `Mandatory Label\\Low Mandatory Level` (`S-1-16-4096`) → **Low integrity level**\r\n\r\nA Low-integrity process cannot open the fixture process (PID 59472, which the host runs at a normal/higher integrity level) with `PROCESS_DUP_HANDLE` (`0x0040 | 0x1000 = 4160`), so `OpenProcess` returns `ERROR_ACCESS_DENIED` (5). Note error `5` (not `87`) confirms the fixture process is alive — access is being refused by the integrity/security boundary, not by process absence.\r\n\r\n## Final status\r\n**Failed — blocked by environment restriction (not a script bug).** The script itself ran correctly: it validated the owned target, obtained host safety admission, and attempted the handle-duplication write. The operation is blocked because the execution environment's Low Mandatory Integrity token cannot duplicate a handle from the higher-integrity fixture process, and the available elevation/outside-sandbox approval does not raise that integrity level in this environment.\r\n\r\nNo files were modified, no protection settings changed, and no software was installed.
