📝 WalkthroughWalkthroughThe change adds automated verification, browser smoke testing, bundle budgets, performance benchmarks, audit statistics caching, frontend visibility polling, and URL-based logo rendering. It also separates Vitest logic and UI projects and improves process cleanup. ChangesTooling and runtime updates
Estimated code review effort: 4 (Complex) | ~60 minutes Merge Risk: 🔵 Low · up to Latency reporting can overstate tail performance, and an invalid configured Chromium path can pass the environment check before browser smoke fails. These are bounded verification issues that should be corrected. Sequence Diagram(s)sequenceDiagram

🩺 Stability & Availability | 🟡 Minor | ⚡ Quick win
Validate that the selected Chromium binary can run.
existsSync(browser) accepts directories and non-executable files. browser-smoke.mjs passes the selected path to chromium.launch({ executablePath }), so npm run doctor can report success before the smoke test fails. Check command(browser, ["--version"]); Chromium supports this flag on the supported platforms.

🎯 Functional Correctness | 🟡 Minor | ⚡ Quick win
Calculate the p95 index with nearest-rank semantics.
For the 20-sample rewrite benchmarks, this expression selects index 19. That value is the maximum sample, not p95. Use ceil(samples * 0.95) - 1 for the zero-based index.
Proposed fix
fn measure(mut work: impl FnMut(), samples: usize) -> serde_json::Value {
+ assert!(samples > 0);
for _ in 0..5 {
work();
