Summary

Launch E2E now sends two messages and shutdown input through a real PTY, then qualifies each launch from ordered OpenClaw session records. Terminal output and message wording are retained only for bounded failure diagnostics and do not determine pass or fail.

Related Issue

Fixes #9160

Changes

  • Record an in-sandbox session baseline and require exactly two ordered user/assistant pairs from each of two PTY launches.
  • Reject stale, malformed, partial, duplicate, extra, cross-session, rewritten, truncated, and out-of-order evidence without comparing message content.
  • Replace gateway recovery prose checks with process identity, guard health, inference health, and stability evidence.
  • Remove the OpenClaw-specific launch qualifier from Hermes until Hermes has an accepted structured-session contract.
  • Add deterministic support coverage and document the contributor-facing evidence model.

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)

  • Tests not applicable, justification:
  • Docs updated for user-facing behavior changes
  • Docs not applicable, justification: Product behavior is unchanged; test/e2e/README.md documents the contributor-facing test contract.

Documentation Writer Review

  • Documentation writer subagent reviewed the completed changes

  • Evidence: test/e2e/README.md documents the real PTY, two messages per launch session, ordered structured session evidence, content-independent qualification, and diagnostic-only terminal output.

DGX Station Hardware Evidence

  • Tested on DGX Station
  • Tested commit: Not applicable
  • 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: file-local pre-commit hooks, commit-msg, and pre-push passed. repository-checks was skipped for the final commit because unchanged main reports that handleRemoteProviderSelection decreased from 80 to 76 and requires its unrelated budget to be lowered.
  • Targeted behavior tests pass for the current change set, or tests are marked not applicable above: npm run test:changed passed with 6 tests and 6 Linux-only macOS skips; the six-case Linux real-PTY matrix passed valid ANSI/plain capture, invalid order, child failure, cleanup failure, preserved exit status, TTY, and cleanup cases; npm run test:e2e-phases:check passed for 127 tests across 83 files; the changed support test has zero AST if statements.
  • Applicable broad gate passed: npm test for broad runtime/test-harness changes; npm run check for repo-wide validation/coverage changes. npm test timed out after 600 seconds with unrelated platform and environment failures; the changed launch-helper test did not fail. CI is pending.
  • 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): passed with zero errors; Fern reported two existing hidden-page warnings.
  • Doc pages follow the style guide (doc changes only)
  • New doc pages include SPDX header and frontmatter (new pages only)

Summary by CodeRabbit

  • Tests
    • Strengthened launch-readiness validation with two successful terminal sessions and two ordered user/assistant message pairs.
    • Added checks for structured session evidence, integrity, configuration restoration, and cleanup.
    • Expanded coverage for malformed records, terminal behavior, crash recovery, gateway recovery, and lease orchestration.
    • Removed brittle exact-text and recovery-path assertions while retaining exit, health, state, and inference checks.

📝 Walkthrough

Walkthrough

Launch-readiness validation now drives two PTY sessions and verifies ordered user/assistant records in the OpenClaw session store. Terminal text and recovery messages are no longer behavioral assertions. Hermes uses a separate session contract.

Changes

OpenClaw launch qualification

Layer / File(s) Summary
Session evidence runner
test/e2e/live/launch-agent-turn.ts
The launch helper records a baseline, validates append-only structured session evidence, drives two unique PTY turns, and reports bounded diagnostics.
PTY and evidence validation
test/e2e/support/launch-agent-turn.test.ts
Support tests cover valid and invalid session records, PTY behavior, cleanup, exit propagation, and two-launch lease orchestration.
OpenClaw launch-readiness integration
test/e2e/README.md, test/e2e/live/full-e2e.test.ts, test/e2e/live/launch-readiness-lease-acceptance.test.ts
Acceptance and full E2E contracts require two PTY launches with two ordered structured turns per launch.
Recovery and Hermes boundaries
test/e2e/live/gateway-guard-recovery.test.ts, test/e2e/live/hermes-e2e-phases.ts, test/e2e/live/hermes-e2e.test.ts, test/e2e/live/issue-2478-crash-loop-recovery.test.ts
Recovery checks no longer require exact output messages. Hermes no longer runs the OpenClaw session-store qualifier, and crash-loop probes no longer record recovery paths.

Estimated code review effort: 4 (Complex) | ~45 minutes

Merge Risk: 🟡 Moderate · up to ead04

The PR strengthens E2E launch qualification using ordered PTY-backed session evidence without changing product behavior. Targeted validation passes, but the applicable broad test gate timed out and CI remains pending, so merge requires a successful rerun or explicit maintainer acceptance.

357-372: 📐 Maintainability & Code Quality | 🔵 Trivial | ⚡ Quick win

Prove that the terminal-text path is gone, not only that the new path works.

The lease test asserts the new env contract. It does not assert that the removed readiness-text and expected-reply env fields are absent. A regression that reintroduces terminal-text matching would still pass.

Add an assertion that the launch env exposes no readiness or expected-reply keys.

As per path instructions for **/*.test.{ts,js,mts,mjs,cts,cjs}, "Migration tests must prove the superseded path is unreachable or removed, not merely prove that the new path also works."

Separate the pending status from unexpected script failures.

Status 1 means "turns not yet complete". Node also exits 1 on an uncaught exception. If the verifier throws for an unforeseen reason, wait_for_turn_count reads status 1, keeps polling for the whole budget, and then reports "launch did not record the required structured session turns". The real cause stays hidden.

Map unexpected errors to the invalid status instead.

-if (mode === "qualify") qualifyTurns();
-finish(2, "mode_invalid");

- Around line 211-228: Update terminal_diagnostic and every caller in the
launch-agent session flow to ensure PTY capture output is redacted using the
run’s redactionValues before writing to stderr; preserve only bounded,
content-free diagnostics when redaction values are unavailable, including the
empty-list path used by launch-readiness-lease-acceptance.test.ts.
- Around line 326-333: Reorder the checks in the launch flow so the
`launch_status` nonzero branch runs before handling `remove_session_baseline`
failure, preserving and exiting with the original launch status. Report
baseline-removal failure only when the launch itself succeeded, while retaining
the existing `fail_launch_session` behavior and cleanup trap.

1 additional E2E selection from the second opinion

Advisory only. The primary lane did not select these E2E jobs or targets.

  • ubuntu-repo-cloud-openclaw: The completed second-opinion lane identified E2E coverage that the primary lane omitted.

Second-opinion terminology and E2E selections are advisory. Live E2E does not run automatically for pull requests.

3 semantic terminology decisions

Terminology decisions are advisory. They affect the assessment only when a separate finding identifies concrete semantic impact.

  • define — structured session evidence at test/e2e/live/launch-agent-turn.ts:273: Define this term at its first contributor-facing use. Keep terminal diagnostics distinct from qualification evidence.
  • justified — session baseline at test/e2e/live/launch-agent-turn.ts:217: Keep the modifier. It names the pre-launch evidence boundary.
  • justified — bounded failure diagnostic at test/e2e/README.md:343: Keep the modifier. It distinguishes diagnostic output from qualification evidence.

Advisory only. A maintainer can dispatch the default E2E suite for the commit under review.
