Drive a real Chrome window to inspect pages, fill forms, click through flows, and extract data.

• Selector-first target contract: interact via numeric refs (resilient to DOM drift) or CSS selectors, with structured match_level feedback (exact, stable, reidentified) on every action
• Session lifecycle management: use stable session names for multi-step flows, bind existing tabs for logged-in pages, and leverage idle timeouts or explicit close for cleanup
• Compound form metadata: date/time/select/file controls expose format strings, option lists (capped at 50), and current values—use these instead of regex-guessing or blind clicks
• Network capture and extraction: inspect API responses by shape, fetch full bodies on demand, or use extract with continuation cursors for long-form content
• Structured error codes and candidates: branch on code (not message strings), and use candidates or available arrays to recover from ambiguous selectors or missing options
