Archive, privacy, receipt, and evidence-lifecycle companion layer for JEP v0.6.
This repository hosts the interactive reference implementation of HJS v0.5.
HJS v0.5 upgrades the previous v0.4 implementation into a JEP v0.6-compatible companion implementation. It can generate HJS/JEP-style signed events, preserve human privacy controls, and create archive receipts bound to JEP event hashes.
JEP = atomic signed judgment events
HJS = archive, privacy, receipt, and evidence lifecycle
JAC = causality and accountability chains
HJS v0.5 does not redefine JEP-Core verbs, signatures, event hashes, validation levels, validation modes, or failure codes.
| Area | v0.5 Capability |
|---|---|
| JEP event support | J/D/T/V event generation and validation baseline |
| Event hash binding | JEP-style algorithm-tagged event hash over signed event object |
| Archive receipt | hjs.archive_receipt with receipt_time and archive_time |
| Redaction | redaction_manifest seed structure |
| Selective disclosure | selective_disclosure_manifest seed structure |
| Evidence lifecycle | evidence_refs and retention policy metadata |
| Privacy | plaintext, ephemeral DID, public key hash, salted digest |
| Boundary | no external truth, legal liability, or complete-log determination |
