Why is Jev's result not treated as permission?

The design rule is that a probabilistic judgment should be evidence, not authority: admission decides whether it may enter governance at all, and only accepted evidence can change relation state.

Does it need API keys to run?

No, the fixture mode replays recorded Jev-style judgments with no network; live mode reads TYPESAFE_API_KEY and sends the task, tool, scope and intent to Jev.

What does the admission policy decide before governance changes?

Admission v0.1 returns Reject(reason), Hold(reason) or Accept(Strong or Corroborated); only Accept is allowed to emit governance-active EvidenceAdmitted input, so a probabilistic score cannot silently become authority.

What inputs does the admission policy consider?

It considers typed evidence kind, confidence in integer parts-per-million, caller-bound source reliability, independent corroborator count and virtual-time expiry, which keeps the policy small and falsifiable.

Do rejected judgments erase prior governance state?

No. The demo's second act shows rejected evidence leaves relations unchanged, so authorization stays suspended by earlier accepted evidence instead of being reset.

Can I run r2r-jev without sending data anywhere?

Yes. cargo run -- fixture replays a recorded Jev-style judgment with no network, and ids plus virtual ticks are deterministic, so the same event sequence and admission policy reproduce the same result.

What language is r2r-jev written in?

It is a Rust project under Apache-2.0 that runs with cargo; live mode adds CLI flags for task, tool, scope and intent plus optional source-reliability and corroborator metadata.

R2r Jev

Agent governance integration where Jev judges two Noul checks per tool call (beyond scope, destructive), an admission policy decides which judgments may become evidence, and admitted evidence degrades Trust, Delegation and Authorization in persistent R2R relation state.

About this project

r2r-jev is a small public integration built around one rule: Jev turns unstructured state into typed probabilistic decisions. Evidence Admission decides which observations are eligible to enter governance. R2R turns admitted evidence and events into persistent, replayable relation state. The primary execution path is now: Most agent guardrails answer a local question: Evidence Admission adds a second question before persistent state is allowed to change:

Highlights

Runs the full governance path offline with a recorded Jev-style fixture; live mode adds a TypeSafe key and CLI flags
Admission v0.1 returns Reject, Hold or Accept (Strong or Corroborated), and only Accept may emit governance-active EvidenceAdmitted
Built-in counterexamples: 99.9% confidence from a low-reliability source is rejected, and 76% confidence needs two corroborators to be accepted
Evidence confidence is converted to integer parts-per-million at the adapter boundary; ids and virtual ticks are deterministic
Three-act demo shows DENY from accepted evidence, unchanged state from rejected evidence, and a human override that restores authorization under supervision

Watch out

Apache-2.0. Intentionally small: it demonstrates the integration boundary rather than the full R2R runtime, and Admission v0.1 is described as deliberately minimal.
