Janus Governance Core — Demo Runtime (Node)

Reference Runtime: v0.1.0

This minimal demo proves:

1) Append domain activity to MANAGEMENT_LOG 2) Read SCHEMA_LOG as reference 3) Form evidence as E+ / E- 4) Run a governance evaluation layer (beyond omission detection) 5) Write canonical governance events to AUDIT_LOG only through an Audit Writer boundary

Run

From this folder:

• node demo.js

From repo root:

• node runtimes/demo-node/demo.js

Expected behavior

• Flow A (omission): appends CHANGE_PROPOSED, evaluates, emits OMISSION_DETECTED with E- into AUDIT_LOG
• Flow B (approved): appends CHANGE_PROPOSED + HUMAN_DECISION, evaluates, emits HUMAN_DECISION_REGISTERED with E+ into AUDIT_LOG
• Flow C (rebuild): rebuilds a minimal state only from logs and prints a summary object

This runtime is a reference proof of the Janus Core Lite model, not a production runtime.
