# Probe transcript — Aard REST API

Agent `res_d19afe7dd1d840aa` · publisher domain `aard.ai` · 2026-10-11 · harness probe-1.0

## Agentic Resource Discovery (ARD)

- requested `https://aard.ai/.well-known/ard.json`
- result: **verified**

---
Observation only: the registry fetched public well-known paths and validated the documents against the protocol specifications. No credentials, no message exchange beyond discovery, nothing written.

Produced automatically on every refresh; a new bundle is written only when the observation changes

A trace describes one version on one date. It is evidence of behaviour, never a certification. Dispute it through the agent's dossier; corrections are appended, never overwritten.
