test(update): let the test-scoped Windows ACL belt through the host-free helper - #7487
Conversation
…ree helper #7468's withoutHostProcesses refused every spawn, including the icacls.exe that config writes run on Windows against the test home, and failed 9 update-job cases on windows 9/9. Pass through exactly %SystemRoot%\System32\icacls.exe when every path argument is inside OPENCODEX_HOME or the temp dir, record it in a separate allowed list, and keep refusing everything else.

- Line 82: Update the icacls argument validation around the paths mapping so
relative path operands are not silently discarded and executed unchecked.
Identify and validate the path supplied to options such as /save, including the
relative aclfile form, while preserving acceptance of the existing scoped
absolute paths; add coverage for /save with a relative filename.
- Around line 86-87: Update the Windows containment check in
isTestScopedWindowsAcl to resolve both roots and targets with win32.resolve
before comparison, then use win32.relative to reject traversal outside each root
while allowing the root itself and descendants. Add a test covering a path
containing .. that escapes the configured test root.

…ical target Review (#7487): a '..' segment passed the prefix check, and switches such as /save took a relative file operand outside the test roots. Allow exactly the argv shapes src/lib/windows-secret-acl.ts builds, resolve the target with path.win32.resolve before the containment check, and test the refusals.

Summary
devCI went red on Windows after #7468 merged: run https://github.com/lidge-jun/opencodex/actions/runs/39606758443,windows 9/9. #7468'swithoutHostProcesseshelper refuses everyBun.spawnSyncduring the update-recovery scenarios and asserts that none were attempted. On Windows, the config writes those scenarios make run the ACL belt (src/config/atomic-write.ts,src/config/paths.ts),C:\\Windows\\system32\\icacls.exe, against the test home. The helper exempted only the PowerShell wrapper cleanup, so 9 cases intests/update/update-job.test.tsfailed at the "no host launches" assertion. Production tolerated the refusal; only the test assertion failed. PR CI didn't catch it because the Windows shards run only after merge or by dispatch.This is a test-only fix. The helper now passes through exactly
%SystemRoot%\\System32\\icacls.exe, and only when every path argument is inside the test'sOPENCODEX_HOMEor the temp directory, which restores the coverage these scenarios had before #7468. Allowed launches are recorded in a separateallowedlist (readable through an optionalobservedargument) and asserted to be that binary on win32 only. Everything else is still refused and counted.Verification
