Laya Ultrafast
A local Apple Silicon browser agent port of jev-ultrafast that uses Laya typed decisions by default and retains hosted Jev as an optional mode.
Added to Jevfast
How it uses Jev
When DECISION_MODEL=typesafe is selected, the original upstream agent asks Jev to choose an operation and a compatible observed target. The port defaults to local Laya, but retains this hosted Jev policy unchanged as an optional mode.

App workflow
- Observe and ask
Build action candidates from the current page snapshot, then ask Jev for the operation and compatible target in one request.
- Validate and act
Validate the operation and target against observed actions, execute the operation, then observe the page again. The example independently checks its final page.
Why it is interesting
Separates narrow typed judgments from reusable browser rules and makes the policy switch explicit.
