Agent Apply Mutations

Request for POST /api/v1/studies/{study_id}/agent/apply.

Response from public v1 agent endpoint.

Returns the agent's mutations alongside the materialized post-edit state. Customers can either use the materialized fields directly, or POST the mutations to /agent/apply to persist them.

Each question in questions carries a mentions array resolving its {{Q:...}} references to {placeholder, referenced_question_id, label, type, property_name, property_index, valid, error}, so consumers can render and understand references without parsing tokens. broken_mentions lists any invalid references in the post-edit state (entries with newly_broken=true were broken by this edit). Randomizer edits are materialized in routing_nodes, routing_branches, and the routing ownership fields on questions and question groups.
