# Visual Diff Review ## Mandatory CloakBrowser Boundary This boundary applies before every browser action: 1. Run exactly: ```bash $HOME/.local/bin/cloakbrowser-cdp-health ``` If the command is missing or exits nonzero, stop immediately and report `NOT_PROVEN`. 2. Browser execution is permitted only through: - the exact `$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`.
