Successful Response

- ClinicalTrialDetailResponse — Detail endpoint returns a flat trial object (same shape as ClinicalTrialResult). reportedEvents is only populated on trials with hasResults=true.
  - `reportedEvents` ReportedEvents — Adverse events table as stored by ClinicalTrials.gov and indexed by Resolute. Only present on trials that have results (hasResults=true). Contains the time frame of observation, group definitions, and a flat list of serious/other adverse events with per-group counts. Resolute may return a single-element object instead of a list for groupList and events when there is only one item (XML-to-JSON coercion artifact). Both shapes are accepted.

      - `subtitle` FacetValue — A faceted field value as returned by Resolute's formatter. Resolute returns faceted fields as {id, name} dicts, optionally with a "highlighted" key containing HTML-marked-up text when the field matched the search query. The id is the ES-stored value (filterable), and name is the display value (may differ due to es_to_name transforms, e.g. country codes).
