Visual Diff Review

Mandatory CloakBrowser Boundary

This boundary applies before every browser action:

1. Run exactly:

   $HOME/.local/bin/cloakbrowser-cdp-health
   

   If the command is missing or exits nonzero, stop immediately and report NOT_PROVEN.

2. Browser execution is permitted only through:

   • the exact $HOME/.local/bin/playwright-cli executable; run-code and --filename are forbidden;
   • the approved Chrome DevTools MCP transport, exactly /bin/sh -c 'exec "$HOME/.local/bin/chrome-devtools-mcp" --headless --isolated --no-usage-statistics --no-performance-crux'.

3. Never execute the Webwright Python runtime, stock/raw/in-app Browser, browser_agent, node_repl, computer-use, Playwright MCP, raw Playwright, bunx, npx, direct package invocations, alternate CDP endpoints, alternate browser executables, alternate browser configs, or any fallback. No fallback is allowed.

Required evidence:

• A reference source: Figma frame export, user-provided image, screenshot, or accepted product reference.
• An actual screenshot captured after a successful health check through the exact managed CLI.
• A diff or measured element-level deviation report.
• Responsive viewport evidence when layout is responsive.
• Health-gated managed Chrome DevTools MCP diagnosis when computed layout, network, runtime, performance, or memory explains a deviation.

If the managed providers cannot prove a required state, report NOT_PROVEN.
