Report #92486

[frontier] Screenshot-based agents accumulate 200-500ms latency per action waiting for visual confirmation

Implement predictive rendering using DOM mutation observers to anticipate visual outcomes; speculatively execute next action based on predicted state, verify asynchronously with screenshot

Journey Context:
Standard computer-use loop: Action → Wait → Screenshot → Verify. DOM state changes faster than visual rendering \(CSS transitions, lazy loading\). Solution: Use Playwright's request/response interception and DOM mutation observers to detect when page reaches quiescence. Predict final visual state from DOM diff. Execute next action optimistically. If subsequent screenshot contradicts prediction, rollback state and retry. Reduces critical path latency by 60-80% for multi-step workflows.
