Summary

Carries #6726 by @sungyongcho so it runs under repository CI (fork CI needs maintainer approval).

Two tests in tests/clients/link-ssh-argv.test.ts fail on any host that already has ocx in /usr/bin, such as a machine with the OpenCodex desktop .deb. Both simulate the remote PATH as /usr/bin:/bin and expect the stub in ~/.bun/bin to run. The remote prelude appends ~/.bun/bin after the remote PATH on purpose, so a host ocx wins and the stub never runs.

The two tests now use a remote PATH that holds only an sh symlink to /bin/sh. The first test's expected PATH line follows the new base. Production code and the other tests are unchanged; the ordering contract stays enforced by the literal prelude assertion and the "an ocx the remote PATH already resolves wins" test.

Closes #6726 once landed (the source PR is closed manually after this merges).

Verification

• bun test tests/clients/link-ssh-argv.test.ts on macOS with broken ocx shims on PATH: 18 pass, 1 skip (the Windows-only PowerShell case), 0 fail.
• Regression guard: changing REMOTE_OCX_SCRIPT in src/link/ssh-argv.ts to prepend the fallback directories makes 3 tests fail (prelude literal, append ordering, remote-PATH ocx wins); restored afterwards.
• Independent gpt-6.1-sol review of c15037b324...1878576851: PASS.
• Full suite not run locally (test-only change to one file); hosted Cross-platform CI on this head is the remaining evidence.

Checklist

• Scope stays focused and avoids unrelated cleanup. (One test file.)
• Docs or release notes were updated when needed. (None needed for a test-only change.)
• Security-sensitive changes were reviewed for secrets, auth, and unsafe defaults. (No runtime, credential or workflow changes.)

📝 Walkthrough

Walkthrough

Two SSH argument tests now use a temporary remote PATH containing only a sh symlink. The prelude test checks the updated PATH and retained arguments. Production code and other tests are unchanged.

Changes

Remote PATH test isolation

Layer / File(s)	Summary
Isolated remote PATH for SSH tests tests/clients/link-ssh-argv.test.ts	A helper creates a temporary directory containing a sh symlink. The remote-prelude test uses this PATH and checks the resulting PATH and retained arguments. The POSIX argument-bytes test uses the same isolated PATH.

Priority: ⬇️ Low

Estimated code review effort: 2 (Simple) | ~10 minutes

Change: Other · Severity of issue fixed: Low

Merge Risk: ⚪ Minimal · up to 18785

The change isolates the SSH argument tests from host-installed ocx binaries without removing their shell or PATH-ordering checks. No actionable merge risk remains; normal CI should still run.
