Summary

• Gives the timestamp-hover browser regression its own 20-second test budget.
• Keeps every existing hover, layout, and click assertion unchanged.
• Prevents the outer Vitest default from expiring before the test's existing 10-second browser wait.

Linked context

Requested as part of July beta release validation cleanup.

Real behavior proof (required for external PRs)

• Behavior or issue addressed: the browser test timed out at the default 5 seconds while its inner element wait permits 10 seconds.
• Real environment tested: Blacksmith Testbox Chromium run.
• Exact steps or command run after this patch: focused pnpm test ui/src/pages/chat/chat-responsive.browser.test.ts through the repository Crabbox wrapper.
• Evidence after fix: 55/55 tests passed; the affected case passed in 1.529 seconds.
• Observed result after fix: the browser contract remains fully asserted with a bounded outer timeout.
• What was not tested: full beta validation is running separately.
• Proof limitations or environment constraints: Tahoe remains stopped; no macOS proof was run.
• Before evidence: https://github.com/openclaw/openclaw/actions/runs/29184485559/job/86628035477

Tests and validation

• Focused Testbox Chromium suite: 55/55 passed.
• git diff --check: passed.
• Fresh autoreview: clean, no actionable findings.

Risk checklist

• User-visible behavior change: No.
• Config, environment, or migration behavior change: No.
• Security, auth, secrets, network, or tool execution behavior change: No.
• Highest-risk area: accidentally masking a deterministic UI regression.
• Mitigation: assertions and inner waits are unchanged; only the contradictory outer budget is raised and remains bounded.

Current review state

Next action: hosted CI, then land into release/2026.7.1 if green.
