# Reorder the top-level items of a session (freestyle)

> Freestyle (performance-based) equivalent of the plan-day item reorder. Reorders the TOP-LEVEL list the freestyle screen renders, where a superset is a single block. List EVERY top-level unit in the new order: a standalone performance as `{ type: "exercise", performanceId }`, or a whole superset as `{ type: "superset", groupId }` (its internal order is preserved). `order` is reassigned as a contiguous sequence, expanding each superset into a contiguous run. Must be a full cover — every standalone and every superset listed exactly once.

Requires the workout_sessions:write scope. This operation maps to /app/v1/workout/performance/sessions/:sessionId/items/reorder and retains its Workout V2 permission, feature-flag, and resource-scope checks.

The clientId path parameter is resolved inside the company bound to the Public API token when present.
