The exercises do NOT need to already be in the day: each catalog exercise is appended to the moment as a new exercise and tagged with a shared generated `groupId`. The `exerciseIds` **array order defines the in-superset sequence**. Each selected exercise is validated for existence + visibility (same contract as createWorkoutExercise). The new superset is appended at the end of the day with contiguous `order` slots (existing exercises are not displaced); new exercises use schema defaults (type `reps`, etc.). The model does not impose a maximum number of exercises per group. Requires the workout_plans:write scope. This operation maps to /app/v1/workout/plans/template/:planId/moments/:planMomentId/supersets 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. ## OpenAPI ````yaml /openapi/public-v1.json post /public/v1/workout/plans/template/{planId}/moments/{planMomentId}/supersets openapi: 3.1.0 info: title: FITsociety Public API v1 version: 1.0.0 description: >- Developer Public API endpoints under `/public/v1`.
