Product Positioning & Context

AI Executive Synthesis
Ensuring robust, reliable agent initialization and observation by preventing premature termination due to transient DOM states. The goal is a resilient agent that correctly waits for a fully interactive and populated DOM before policy decisions, maximizing successful task execution and minimizing `BLOCKED` states.
This issue exposes a critical reliability flaw in the `jev-ultrafast` library's agent initialization, leading to immediate task failure. The `Browser.__init__` logic incorrectly validates `document.readyState` against an `about:blank` state, causing the system to proceed with an incomplete DOM. This results in an 'empty action space' for the agent, which then deterministically terminates as `BLOCKED`. This behavior guarantees a 100% failure rate on cold starts, rendering the agent unusable for initial interactions. The lack of retry logic for degenerate snapshots, only for `StalePage` exceptions, indicates a fundamental design oversight in handling transient page states. This directly impacts the product's perceived intelligence and operational effectiveness.
