test(e2e): assert visible terminal behavior

[rsliter]

Summary

Launch-turn E2E now matches the exact visible reply and semantic idle state after terminal control sequences, instead of matching incidental TUI prefixes. Gateway recovery tests now rely on exit status and existing process, guard-chain, inference, health, and stability evidence instead of exact operator copy.

Related Issue

Fixes #9160

Changes

• Render visible output after terminated OSC sequences, CSI 2K, carriage returns, backspaces, and nonprinting controls before matching launch-turn output.
• Pass semantic readiness state from OpenClaw callers and require it only after the exact reply appears.
• Remove exact gateway recovery sentence checks where stronger behavioral evidence already follows.
• Add deterministic support cases for accepted and rejected terminal output forms.

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 internal E2E support and live-test assertions. It does not change a user-facing product surface.
• 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 only replaces terminal-copy assertions. Existing process identity, guard-chain, health, inference, and stability evidence remains, and credential and policy behavior is unchanged.
• 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: Commit d3d4a31df changes only internal E2E tests and support code under test/e2e/. The final follow-up adds startup-readiness fixtures for terminal control sequences. It changes no user-facing product surface.

Verification

• 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, command/result or justification: npx vitest run --project e2e-support test/e2e/support/launch-agent-turn.test.ts passed 11 tests and skipped 1 opt-in live test.
• Applicable broad gate passed, npm test for broad runtime/test-harness changes; npm run check for repo-wide validation/coverage changes, command/result:
• Quality Gates section completed with required justifications or waivers
• No secrets, API keys, or credentials committed

Summary by CodeRabbit

• Tests
  • Improved launch readiness checks to recognize normalized terminal state values, including idle and busy states.
  • Added coverage for terminal redraws, control sequences, stale or partial responses, and unrecognized output.
  • Strengthened recovery validation using process identity, guard checks, inference, exit codes, and stability.
  • Removed brittle assertions tied to specific recovery messages.

📝 Walkthrough

Walkthrough

The E2E launch helper now normalizes terminal output, validates exact replies, and checks semantic readiness states. Supporting fixtures cover terminal controls and state transitions. Recovery tests no longer require incidental recovery messages or actor labels.

Changes

Launch readiness and recovery

Layer / File(s)	Summary
Normalize terminal output and readiness states test/e2e/live/launch-agent-turn.ts	Terminal output is rendered consistently. Exact replies and configurable final readiness states use renamed options and environment variables.
Exercise terminal controls and fixture configuration test/e2e/support/launch-agent-turn.test.ts	The fixture uses an options object and covers redraw controls, stale or partial replies, busy states, and unrecognized sequences.
Update callers and recovery assertions test/e2e/live/full-e2e.test.ts, test/e2e/live/launch-readiness-lease-acceptance.test.ts, test/e2e/live/gateway-guard-recovery.test.ts, test/e2e/live/issue-2478-crash-loop-recovery.test.ts	Live callers use idle readiness states. Recovery checks rely on process and health validation instead of exact output text or recovery-path labels.

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

Merge Risk: ⚪ Minimal · up to d3d4a

This PR refines internal end-to-end terminal-behavior assertions without changing the user-facing product surface; no actionable merge-blocking risk remains beyond normal checks and review.

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

• established — visible reply at test/e2e/support/launch-agent-turn.test.ts:284: Keep `visible reply` for rendered terminal output.
• justified — post-reply at test/e2e/support/launch-agent-turn.test.ts:151: Keep `post-reply` to identify the required assertion order.
• justified — idle state at test/e2e/support/launch-agent-turn.test.ts:151: Keep `idle state` for the final TUI state field.

chatting with the agent because I don't like the direction this is going. In draft for now.

[rsliter]

Closing because #9160 now requires real PTY input plus structured OpenClaw session evidence. This PR's terminal renderer and terminal-copy assertions are superseded. I'll replace it with a fresh PR from current main.
