Triggers the ui-verifier subagent in a forked context.

Live browser verification specialist using playwright-mcp. Navigates a running application, executes flows, and produces docs/test/UI_VERIFICATION_REPORT.md with per-flow PASS/FAIL/WARN verdicts and descriptions of what was observed.

Works without vision: Uses accessibility tree snapshots (browser_snapshot()) as the primary verification signal — no vision-capable model required. Screenshots are taken for visual record and described if vision is available.

Modes:

• --smoke (default) — 5 min quick pass over main routes
• --use-cases — verify every P0 use case in USE_CASES.md
• --flow "description" — single flow end-to-end
• --regression — post-change check against last-known state

Requires: playwright-mcp registered (claude mcp list should show playwright). If not registered, run ./install.sh or claude mcp add playwright -- npx -y @playwright/mcp@latest.
