JEP CLI — JEP Core 0.7

Command-line client for creating and verifying current JEP Core 0.7 events through the JEP API.

Default endpoints:

POST /v0.7/events/create
POST /v0.7/events/verify
GET  /health

Historical pre-0.7 handling is explicit through --legacy; the CLI never retries a failed 0.7 event with a legacy decoder.

Status

Experimental reference client. It does not define Core semantics or determine truth, authorization validity, legal effect, causality, or policy outcome.

Installation

pip install jep-cli

Configuration

export JEP_API_URL=http://127.0.0.1:8000
export JEP_API_KEY=

Create

Judgment:

jep create \
  --verb J \
  --who did:example:agent-789 \
  --what '{"claim":"approve","subject":"demo"}'

Delegation:

jep create \
  --verb D \
  --who did:example:principal \
  --what '{"delegatee":"did:example:agent","scope":{"actions":["read"]}}'

Termination and Verification require --ref. Pass a typed reference as JSON when the target is another JEP event.

Verify

jep verify event.json --mode archival

0.7 validation returns status plus independent checks, not a cumulative Validation Level.

Explicit legacy verification

jep verify old-event.json \
  --legacy \
  --legacy-format json-sorted-v1

Legacy selection must come from known artifact context. Do not use a failed 0.7 validation as evidence that an event should be treated as 0.6.

JEP Core 0.7 model

• Event Identity is (who,id).
• Event Hash identifies an exact signed artifact.
• Core does not require a top-level nonce.
• D requires delegatee + scope.
• T requires target ref + termination_scope.
• V requires target ref + verification_scope + result.
• chain and policy semantics remain outside Core.
