JEV Fuse

JEV Fuse is a governed execution layer that translates raw decisions from probabilistic models into deterministic actions like ALLOW, ASK, or DENY, acting as a proxy between decision models and agent tooling.
Been messing around with @typesafeai JEV + agent tooling from last weekend and ended up building a little piece of infrastructure around it.
The weird thing about fast decision models is that you can get a probability in milliseconds.. but a probability isn't an execution policy.
So I built JEV Fuse ⚡
A governed execution layer between decision models and agent tooling (Claude Code, MCP, SDKs) that turns raw decisions into deterministic actions:
ALLOW / ASK / DENY
Under the hood:
• Deterministic shell AST guards
• Deadband abstention around ambiguous decisions
• In-memory caching + singleflight deduplication
• Persistent SQLite audit trail
the idea: don't let a probabilistic output directly touch a production tool.
its a drop-in proxy and completely open source👇
