v0.2 -- February 2026
HJS is a protocol for structural traceability.
HJS is a traceable event recording system. It records verifiable evidence of judgment events, delegation events, termination events, and attribution relationships.
01
The Situation
Automated systems increasingly make irreversible decisions — loan approvals, medical diagnoses, emergency braking. When these decisions are made, responsibility often cannot be clearly reconstructed:
- Delegation happens in chat tools, leaving no trace
- Responsibility never terminates, even after someone leaves
- Attribution lacks verifiable structured evidence
In these scenarios, delegation, termination, and attribution all lack clear responsibility flow records and verification mechanisms.
02
Solution
HJS defines four core primitives — Judgment Event, Delegation Event, Termination Event, and Attribution Relationship — as a minimal, composable layer for recording and tracing structured event flows in socio-technical systems.
| Primitive | Description |
|---|---|
| Judgment Event | The actor, time, and scope of a judgment event |
| Delegation Event | The source, recipient, and validity period of authority transfer |
| Termination Event | The time and type of responsibility or delegation termination |
| Attribution Relationship | A traceable association graph between parties |
