Example: Verified Response

This page shows what a complete AIEP verified response looks like — every field explained.

The question

How can an AI answer be verified?

The response

An AI answer can be verified by binding claims to evidence artefacts,
hashing those artefacts, and validating the response against a declared
evidence rail.

This is not just text. Attached to it is an evidence rail and a validation result.

The evidence rail

Three artefacts were retrieved and hashed before this response was returned:

Field	Artefact ev_001
Source	`aiep.dev/schema/evidence.json`
Confidence	`verified`
Hash	`f3a2c4e0b6a7d991...`
Retrieved	`2026-04-25T00:00:00Z`
Status	`passed`

The hash is a SHA-256 fingerprint of the source content at retrieval time. If the source changes, a future replay will detect the discrepancy.

The validation result

Schema validation:         passed
Hash validation:           passed
Evidence rail present:     passed
Replay metadata present:   passed

Status: PASSED

Validation is performed against the AIEP canonical schema. A response cannot return PASSED without completing all checks.
