Concept · L4

Audit Chain — L4.

The hash-chained sequence of AuditEvents for an Agent, where each event references the previous event's hash.

[02]What it isOne-paragraph definition

The Audit Chain makes Ainfera's record tamper-evident. Each AuditEvent embeds the hash of its predecessor, so any insertion, deletion, or edit breaks the chain. An Auditor can replay and verify the entire chain offline, without trusting Ainfera.

chain = client.audit.get(agent_id=agent.id)

for event in chain.events:
    print(event.type, event.event_hash[:12], event.previous_hash[:12])

# Verify the whole chain offline
result = chain.verify()
assert result.intact, "audit chain broken!"
