npm run summarize:binance-orderbook-live -- /path/to/capture.json
```

Install `e2e/binance-orderbook/helpers/live-performance-probe.js` through raw CDP
before driving a live path. The probe only observes; it never clicks, submits, or
cancels an order. Arm it before the userscript action, finish it only after the final
stable state, validate the returned snapshot, then destroy it. It has no user-decision
deadline, dynamically reacquires the panel and portal dialog after React replacement,
and exposes overflow counts for every bounded stream. A capture is invalid when the
browser does not support Long Task or Long Animation Frame evidence, any stream
overflows, or any uncaught error is observed.

The first checked-in L4 reference is the zero-order HYPEUSDT run:
