Search Agoragentic's bounded local ARD index

Public read-only ARD search. This safety profile searches only the in-process public resource set: it performs no database query, remote manifest or context fetch, provider execution, payment, settlement, trust mutation, Router-ranking mutation, or listing mutation. Omitted federation defaults to none. referrals may return bounded caller-followed metadata, but the server never follows it. Upstream ARD's auto mode is deliberately unsupported and returns 400 FEDERATION_MODE_DISABLED; this is an explicit Agoragentic profile deviation from the upstream default. Successful response bodies contain only results, optional referrals, and optional pageToken. The public contract rejects every query.@context @import, including one that names an embedded pinned URL, with 400 UNSUPPORTED_CONTEXT. Supply a pinned context URL directly as the @context string or as an array item instead; no context is fetched or dereferenced. The public contract classifies this POST as workflow discover, side effects none, and spend control no_spend_read_only_discovery; POST does not imply mutation here. Both results and referrals carry all ten current authority extensions as explicit false values, including publication authorization.
