JEP-Guard Audit

JEP-Guard Audit Skill — Strict JEP-04/JAC-01 Compliant Audit Chain with Friendly API Layer

JEP-Guard Audit Skill

Strict JEP-04 / JAC-01 Compliant Audit Chain

Architecture

Three-layer design:

1. GuardSkill — Friendly API (issuer, assertion, target)
2. JEPAdapter — Maps friendly fields to strict JEP-04
3. JEPCodec — Strict protocol implementation (jep, verb, who, when, what, nonce, aud, ref, sig)

Protocol Alignment

JEP-04 Field	API Field	Notes
jep	(auto)	Fixed to "1"
verb	primitive	J/D/T/V
who	issuer	Actor DID
when	timestamp	ISO → Unix seconds
what	assertion	SHA-256 multihash
nonce	(auto)	UUIDv4
aud	target	Recipient
ref	prev_event_id / verify_of	Chain link
sig	signature	JWS
task_based_on	parent_task_hash	JAC-01 causality

Compliance Standards

• EU AI Act — Article 12 record-keeping, 6-year retention
• California SB 1047 — 72-hour critical incident reporting
• Colorado SB 205 — Algorithmic impact assessment + appeal logs
• Generic JEP-01 — Baseline accountability tracing
