Returns the introduction nanopublications of a given user (creation date, key location, declared public-key hashes), plus session-relative action targets from the viewer's local key (?__LOCALPUBKEY_multi) and site URL (?__SITEURL_multi): conditional retract/derive targets that are owner-gated (?_user_iri = ?__CURRENTUSER_multi_iri) and computed against the same notion of a 'local introduction' as the UI: an introduction SIGNED BY the local key, DECLARING the local key, whose local-key declaration has no location or matches the site URL (nanobench->nanodash). retract_target fires on a local introduction when there is more than one (duplicate cleanup); derive_target fires on a non-local introduction when there are zero local introductions. The retract/derive/local columns are action-mapping data (hidden from display by the result builders). The keys column annotates each declared key hash with its trust-approval status, federated from the trust repo: a checkmark when the key is loaded/approved for the user, a warning sign otherwise.
