Autonomous Browser Agent — 30/30 in 51s
Autonomous browser agent that solves all 30 steps of the Browser Navigation Challenge in 51 seconds. Zero errors, zero LLM tokens, $0 runtime cost.
Uses React Fiber tree traversal — locates the challenge component's onComplete callback in the React internal tree and invokes it directly with a valid proof object. One universal method handles all 26 challenge types (hidden_dom, drag_drop, canvas, websocket, shadow_dom, etc.).
XOR session decoding from sessionStorage to obtain all 30 verification codes upfront. Automatic obstacle dismissal: cookie banners, popups, overlays, fake buttons (15-25 per step).
Stack: Node.js + Playwright (Chromium). Single file ~500 lines. Video recording + JSON report with per-step timing.
