The interface contract,
scope made explicit.
A2UI (a2ui.org) is a declarative JSON UI format a host renders into native widgets. The current Dynamic Feed endpoints return top-level card arrays with no receipt object or receipt reference. They are therefore labelled Unsigned caller-reported preview; a host must not promote them to signed or verified.
What an agent shows the user.
Each example links to its current application/a2ui+json payload. The endpoint is live and CORS-open; the displayed claims remain caller-reported or illustrative, and payload availability is not receipt verification.

These cards are unsigned UI previews. A future verified profile must carry or reference the exact receipt, validate its signature and active lifecycle, and render claimant, signer and witness roles without laundering caller text.
It's live JSON.
Fetch the actual unsigned application/a2ui+json preview. Keyless and CORS-open; do not interpret the top-level array as a signed envelope.

Scope your agent can show.
Current cards demonstrate layout and role labels only. Verification belongs to an exact receipt-aware host path that is not enabled here.
