Summary

Preserve a successful OpenClaw launch when the TUI closes its input reader immediately after publishing the two required structured turns. The harness still requires the real child to exit zero; nonzero exits remain failures and now retain their bounded diagnostics.

This follows the merged startup-message fix in #9422. Two focused current-main runs reproduced the newly exposed exit race after hosted inference, sandbox inference, recovery, and the launch-readiness producer had all passed: run 32112329966 and run 32112353122.

Follow-up to #9384

Changes

  • Treat the post-turn /exit write as best-effort after two ordered structured turns are already qualified.
  • Continue to wait for and require the actual TUI child exit status, reporting both a failed exit-command write and any nonzero child exit.
  • Keep cleanup diagnostics on stderr instead of redirecting the parent shell's stderr for the remainder of the session.
  • Extend the Linux delayed-input fixture to cover a clean TUI exit after the two required turns without increasing the test-file budget.

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: The change runs only after exact PTY identity, noncanonical input mode, and two ordered structured turns are proven. It does not retry input, relax PTY evidence, or accept a nonzero TUI exit.
  • Non-success, skipped, or missing CI check accepted by maintainer — check name, approval link, and follow-up issue:

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 — vitest run --project e2e-support test/e2e/support/launch-agent-turn.test.ts (19 passed; 24 Linux-only tests skipped locally)
  • Applicable broad gate passed — npm test for broad runtime/test-harness changes; npm run check for repo-wide validation/coverage changes — not applicable to this focused live-E2E exit-path change; the targeted support suite, source-shape budget, growth guardrails, repository checks, secret scan, and CLI typecheck passed in npm run validate:pr.

  • No secrets, API keys, or credentials committed
  • npm run docs builds without warnings (doc changes only)

Summary by CodeRabbit

  • Bug Fixes
    • Improved launch cleanup and exit handling when terminal sessions close unexpectedly.
    • Exit commands now handle terminal closure more gracefully and provide clearer diagnostics when launches end unsuccessfully.
  • Tests
    • Updated delayed-input coverage to verify that sessions can complete cleanly after two turns.
    • Improved validation of successful completion when input becomes available later in the launch.

📝 Walkthrough

Walkthrough

The launch test records exit-command submission failures and reports them during unsuccessful launches. The delayed-input fixture exits successfully after its second turn, and the test description reflects this behavior.

Changes

Launch exit flow

Layer / File(s) Summary
Exit-command handling
test/e2e/live/launch-agent-turn.ts
Exit-command write failures are recorded without immediately aborting the launch. Failed submissions are reported before nonzero launch-status diagnostics.
Clean two-turn exit

The delayed-input fixture exits successfully after its second turn. The test description reflects the clean two-turn exit.

Estimated code review effort: 1 (Trivial) | ~5 minutes

Merge Risk: ⚪ Minimal · up to a5b42

The change narrowly preserves successful TUI turns while still requiring a zero exit status and retaining failure diagnostics; no actionable merge-blocking risk remains after normal checks and review.

Reviewed commit d4c09c65d4504b92e9811afcb4db36a792d7bee6. The harness now treats the post-completion /exit write as best effort while preserving the real child status and the existing timeout bound. Targeted verification passed: 20 tests in launch-agent-turn.test.ts; 25 Linux-only cases were skipped on macOS. I found no blocking findings.
