Summary

OpenClaw launch qualification now retries real-PTY input until the in-sandbox structured session records the expected user turn with the submitted input, then waits for the assistant turn. This fixes main E2E run 31862560250, job 94959342356, where one-shot input was sent before the TUI accepted it, without using terminal copy as behavioral evidence.

Related Issue

Related to #9160.

Changes

  • Add a qualify-input evidence mode that binds structured user-turn acceptance to the submitted input.
  • Retry PTY input only while structured user evidence remains pending, while preserving fail-closed handling for invalid evidence and process exit.
  • Add portable duplicate-input coverage and Linux regression fixtures that discard the first submitted line before accepting a later submission and reject a delayed prior-turn duplicate.

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:
  • Docs updated for user-facing behavior changes
  • Docs not applicable — justification: This changes only the internal live E2E PTY driver and does not change a supported user command, flag, configuration, API, policy, default, or runtime behavior.
  • 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:
  • Non-success, skipped, or missing CI check accepted by maintainer — check name, approval link, and follow-up issue:

Documentation Writer Review

  • Documentation writer subagent reviewed the completed changes
  • Result: no-docs-needed
  • Evidence: The final diff changes only test/e2e/live/launch-agent-turn.ts and test/e2e/support/launch-agent-turn.test.ts; repository documentation does not describe this internal input qualification sequence.

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 — npx vitest run --project e2e-support test/e2e/support/launch-agent-turn.test.ts completed with 8 passed and 8 Linux-only skipped on macOS at latest PR commit 5d88c38f; the Linux PTY regressions await CI.
  • 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 two-file E2E driver fix; Oxfmt, Oxlint, and normal path-scoped hooks passed.
  • Quality Gates section completed with required justifications or waivers

📝 Walkthrough

Walkthrough

The launch test adds input-only evidence qualification and a retrying PTY submission helper. Fixtures cover delayed input, duplicate prior-turn input, configurable qualification modes, and structured input validation.

Changes

PTY input qualification

Layer / File(s) Summary
Input-only qualification contract
test/e2e/live/launch-agent-turn.ts, test/e2e/support/launch-agent-turn.test.ts
The verifier accepts expected input, validates structured user content, supports qualify-input before an assistant response, and preserves strict turn qualification.
PTY submission and evidence retry
test/e2e/live/launch-agent-turn.ts, test/e2e/support/launch-agent-turn.test.ts
submit_turn retries PTY input until structured session evidence records it. Fixtures test delayed input, successful retry, duplicate prior-turn rejection, and timeout cleanup.

Estimated code review effort: 3 (Moderate) | ~20 minutes

Merge Risk: 🟡 Moderate · up to 5d88c

This change alters PTY input qualification, but the Linux-only regression tests were skipped locally and are still awaiting CI. Merge should wait for Linux verification or explicit maintainer acceptance of that gap.

Additional automatic-main evidence for this owned failure: run 31870765943, job 94979112049 at 496a9ae1 failed the post-recovery OpenClaw launch in launch-agent-turn.ts with structured-session status 2 and reason message_order_invalid. That main commit predates latest PR commit 5d88c38f; the failure is grouped with this PR’s PTY input and structured-session sequencing root cause. Refreshed PR CI remains active. No manual E2E was dispatched.

## Summary

The maintainer triage runtime test now isolates its standalone Node
process from Vitest's inherited `NODE_OPTIONS`. This prevents the test
runner's source-require hook from rewriting the script's `./shared.ts`
import to missing `./shared.js` in CLI shard 12.

Affected evidence:

- PR #9199 [run 31871412202, job
94980566330](https://github.com/NVIDIA/NemoClaw/actions/runs/31871412202/job/94980566330)
- PR #9204 [run 31871885957, job
94981738690](https://github.com/NVIDIA/NemoClaw/actions/runs/31871885957/job/94981738690)

Both jobs failed the same three assertions in
`test/skills/triage-runtime.test.ts`.

## Related Issue

No issue. This is a shared required-check blocker for #9199 and #9204.

## Changes

- Clear inherited `NODE_OPTIONS` only for the spawned standalone triage
process, which already receives its required Node arguments explicitly.
- Include child stderr as assertion context when the spawned process
exits unsuccessfully.

## Documentation Writer Review

- [x] Documentation writer subagent reviewed the completed changes

failure context; it changes no supported command, behavior,
configuration, API, policy, or documentation contract.
