An /.well-known/agent-card.json with the required fields, a coherent endpoint, and a valid signature (if signed).
Site-wide file — one per host.
This signal isn't a page; the container fetches it at a fixed path, and the
correct/broken/authbroken variant is chosen by the request host. On this host the canonical path(s)
below serve the correct variant. Add
?mode=… to override locally.
Canonical path(s)
Broken variant
