## Briefing
- Stagehand: Stagehand released a pre-release version that exposes browser-side predicate waiting consistently across its SDKs, eliminating transport polling.

## Why it matters
This change moves wait logic from polling to browser-side execution, which can reduce latency and improve reliability for extraction and automation workflows that depend on dynamic page states. It signals a deeper integration with browser internals that may benefit developers building robust scrapers or AI agents.

## Watch next
Will this browser-side wait approach be adopted by other browser automation SDKs?
