test(cli): isolate macOS status subprocess cleanup

[senthilr-nv]

Summary

The macOS platform test selects test-owned OpenShell executables. It asserts normal child completion before checking output. The afterEach hook removes the temporary home and verifies its absence. This prevents a host-side Homebrew-installed OpenShell gateway from starting while preserving the list and status output contracts.

E2E root cause: repro-2666 silent list-status test / subprocess and cleanup phase / output-order plus temporary-home cleanup failures on macOS
Source run: https://github.com/NVIDIA/NemoClaw/actions/runs/32312339289 (run 32312339289, attempt 1)
Source main commit: fde9909a022b2ca281813bb0220dd3bb4093f08c (GitHub Verified)
Failed jobs: macOS compatibility (1/4) (96257900908, https://github.com/NVIDIA/NemoClaw/actions/runs/32312339289/job/96257900908)
Signature: Status subprocesses reached the 30-second timeout after package-managed gateway startup. Assertions then saw only partial startup output, and temporary-home cleanup failed with ENOTEMPTY under the Homebrew bootsnap cache.
Scope: one root cause

Changes

• Restrict the subprocess PATH and select test-owned OpenShell CLI and gateway executables, so the test cannot start a host package-managed gateway.
• Preserve child errors, signals, and nullable status. Require normal child completion before product-output assertions.
• Check classifier and guidance order on stdout while retaining combined stdout and stderr checks for nonempty user output.
• Delete each temporary home and verify its absence after the child exits.

expectCliCompleted checks normal completion for the seven tests that call runCli.

Type of Change

• Code change (feature, bug fix, or refactor)
• Code change with doc updates
• Doc only (prose changes, no code sample modifications)
• Doc only (includes code sample changes)

Quality Gates

• Tests added or updated for changed behavior
• Existing tests cover changed behavior — justification:
• Tests not applicable — justification:
• Sensitive paths changed (security, policy, credentials, preflight, onboarding, inference, runner, sandbox, or messaging)
• Sensitive-path review completed or maintainer-approved waiver recorded — reviewer/approval link/justification: independent nine-category security review of commit aa20ec41fb93859033491cb6338dc56b93d8d54d passed with no findings.
• Non-success, skipped, or missing CI check accepted by maintainer — check name, approval link, and follow-up issue:

DGX Station Hardware Evidence

• Tested on DGX Station
• Tested commit: Not applicable; scripts/prepare-dgx-station-host.sh is unchanged.
• Station profile/scenario: Not applicable.
• Result: Not applicable.
• Supporting evidence: Not applicable.

Verification

• PR description includes a Signed-off-by: line and every commit appears as Verified in GitHub
• Normal pre-commit, commit-msg, and pre-push hooks passed, or npm run validate:pr passed after refreshing origin/main when hooks were skipped or unavailable
• Targeted behavior tests pass for the current change set, or tests are marked not applicable above — after npm run build:cli, node ./node_modules/vitest/vitest.mjs run --project integration test/repro-2666-silent-list-status.test.ts --reporter=verbose --testTimeout 60000 passed 11/11 tests on macOS at aa20ec41fb93859033491cb6338dc56b93d8d54d.
• Applicable broad gate passed — npm test for broad runtime/test-harness changes; npm run check for repo-wide validation/coverage changes — command/result: Not applicable to this one-file regression harness change.
• Quality Gates section completed with required justifications or waivers
• No secrets, API keys, or credentials committed
• npm run docs builds without warnings (doc changes only)
• Doc pages follow the style guide (doc changes only)
• New doc pages include SPDX header and frontmatter (new pages only)

📝 Walkthrough

Walkthrough

The regression tests isolate gateway binaries, expose subprocess completion details, and validate process completion before checking CLI output, exit codes, registry content, classifier ordering, and port-conflict behavior.

Changes

CLI regression test hardening

Layer / File(s)	Summary
Controlled CLI subprocess harness test/repro-2666-silent-list-status.test.ts	The test setup installs a failing gateway, configures executable paths and platform-specific PATH, and adds completion checks for spawn failures and timeouts.
Completion and output assertions test/repro-2666-silent-list-status.test.ts	List and status scenarios validate subprocess completion before checking stdout, exit codes, registry content, classifier ordering, and port-conflict behavior.

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

Merge Risk: 🟡 Moderate · up to aa20e

The change is localized and the targeted macOS tests pass, but required checks remain failing on three unrelated jobs that also fail on the base commit; without maintainer acceptance or a waiver, the PR is not merge-ready.

Use the repository’s POSIX PATH separator.

This test harness uses POSIX executable paths. Use ":" instead of path.delimiter to keep the environment explicit and deterministic.

-        PATH: [binDir, "/usr/bin", "/bin", "/usr/sbin", "/sbin"].join(path.delimiter),
+        PATH: [binDir, "/usr/bin", "/bin", "/usr/sbin", "/sbin"].join(":"),

Based on learnings, “prefer the established POSIX PATH separator : ... Do not replace it with path.delimiter in these unit/integration tests.”
