Summary

• add a focused smoke test for scripts/codex-multi-auth.js
• verify the wrapper loads the built CLI entry and forwards args with the package version env
• improve coverage for a previously untested CLI entrypoint script

Validation

• npm run typecheck
• npm run lint -- test/codex-multi-auth-wrapper.test.ts
• npm run test -- test/codex-multi-auth-wrapper.test.ts
• npm run build
• manual QA: node scripts/codex-multi-auth.js auth --help

note: greptile review for oc-chatgpt-multi-auth. cite files like lib/foo.ts:123. confirm regression tests + windows concurrency/token redaction coverage.

Greptile Summary

adds a focused smoke test for scripts/codex-multi-auth.js that verifies the wrapper correctly injects the package version into CODEX_MULTI_AUTH_CLI_VERSION and forwards cli args to runCodexMultiAuthCli. the previous concern about bare fs.rm in cleanup is fully resolved — the test now imports and uses removeWithRetry from the shared helper.

• removeWithRetry is correctly used in afterEach with recursive: true, force: true — windows antivirus/ebusy safety is satisfied
• pop()-based cleanup loop preserves unprocessed entries in tempRoots if an earlier cleanup throws, which is actually more resilient than the splice(0) pattern in the sibling test
• the readFileSync block (lines 60-65) re-reads the copied script and asserts it contains "runCodexMultiAuthCli" — this is tautological and only tests that copyFileSync worked; the behavioural assertions on stdout are sufficient
• spawnSync result is used without first checking result.error, making spawn-level failures produce cryptic assertion messages
• exit-code normalization (non-integer → 1, non-zero integer propagation) is not tested here, but those paths are already covered by codex-multi-auth-bin-wrapper.test.ts

Confidence Score: 4/5

• safe to merge — the one prior blocking concern (bare fs.rm) is resolved; remaining notes are non-blocking style improvements
• the main issue flagged in the previous review round is fully addressed with removeWithRetry. the test correctly exercises the version-env and args-forwarding paths. two p2 style issues remain (tautological readFileSync assertion, missing result.error guard) but neither affects correctness or windows safety.
• no files require special attention

Comment:
**tautological `readFileSync` assertion**

reading the copied script back and asserting it contains `"runCodexMultiAuthCli"` only verifies that `copyFileSync` reproduced the source file — not any runtime behaviour of the wrapper. the string is hardcoded in `scripts/codex-multi-auth.js` and will always be true. consider replacing or dropping it; the `stdout` assertions on lines 57-58 already give you meaningful behavioural coverage.

```suggestion
		// The stdout assertions above cover the meaningful behaviour;
		// no need to re-read the script file here.
```

How can I resolve this? If you propose a fix, please make it concise.

Comment:
**unguarded `spawnSync` result**

if the node process fails to spawn (bad path, missing exec, etc.), `spawnSync` sets `result.error` and leaves `result.status` as `null`. asserting `toBe(0)` on a null will produce a cryptic failure. a quick guard at the top of the assertion block makes failures much easier to diagnose:

```suggestion
		expect(result.error, "spawnSync failed").toBeUndefined();
		expect(result.status).toBe(0);
		expect(result.stdout).toContain("version=9.9.9-test");
		expect(result.stdout).toContain("args=auth --help");
```
