Stopline v0.1.0

Stopline is an experimental decision gate for browser agents. It separates model classification from deterministic authorisation: hard rules and policy code decide whether a proposed action is allowed, requires a human, or is blocked.

This initial source release includes:

  • the TypeScript gate and policy implementation
  • a 49-case labelled evaluation across common browser surfaces
  • a repeatable Playwright demo and local fixture site
  • JSONL evidence logging
  • Jev and local Laya backend paths
  • policy tests and setup documentation

The evaluation is an initial measurement on hand-labelled cases. This release is not a production safety certification, and the demo uses a fixed script rather than an LLM planner.

See the README for setup, evaluation commands, limitations, and the related review exercise.
