On native Windows with the npm-installed codex.cmd shim, this passes the bare profile name into Popen, which searches only executable extensions rather than honoring PATHEXT; the repository already handles this exact case by passing shutil.which()'s resolved .cmd path in opencode_http.py. As a result, adapter.binary can report Codex as found while every hooks.trust query becomes unverifiable, making validate fail for an otherwise runnable supported Windows setup. Pass the resolved executable into project_hook_trust rather than reusing profile.binary.

This validation only rejects hook-affecting arguments stored on the profile, but the actual adapter replaces profile.bypass_args with each role's resolved policy extra_args. For example, codex --help documents -C/--cd as changing the working root, and extra_args = ["-C", "/another/project"] is accepted after the prompt by the same argv shape used in GenericAdapter.interactive_argv; validation can therefore report the current checkout's hooks as trusted while the session loads hooks for another directory and stalls waiting for Stop. Validate each role's effective arguments, or fail the trust check closed when policy arguments can alter discovery.

shutil.which using the same PATH from env before passing it to subprocess.Popen,
while falling back to the original binary when resolution fails; add the
required import and preserve the existing app-server arguments and process
environment.

- Around line 51-67: Make the Codex stub setup in tests/test_codex_trust.py
Windows-compatible at lines 51-67 and 324-340: either skip both affected tests
on win32 or create a Windows-compatible .cmd launcher instead of invoking the
extensionless shebang stub directly. Preserve the existing test behavior on
non-Windows platforms.

When a checkout is moved or its .codex/hooks.json is copied from another checkout, the configured commands can still point at the old absolute relay path. _commands treats any marker-containing command from that config as the expected command, so if Codex reports that stale handler as trusted, validate emits hooks.trust as current even though the current session's Stop event will reach the wrong relay and can leave the unattended loop waiting indefinitely. Derive and compare the expected relay command for project instead of accepting the configured string as ground truth.
