User and Group Directory

Finds users and groups visible to the caller and returns their identifiers.

📄️ Batch-resolve subject ids to display-safe summaries

Resolve up to 100 user or group identifiers in input order. Identifiers outside the caller's visibility scope and missing identifiers are omitted, and duplicate inputs produce one result.

📄️ Search Subjects

Search users and groups visible to the caller. `search` must contain at least two characters. Results rank exact identifier matches before prefix and substring matches, and `next_cursor` is always null in the current contract.
