…stances - Added database count queries: CountProjectsByUser, CountDefinitionsByUser, CountInstancesByDefinition, CountProjectsUsingInstance, CountSharedUsersForInstance - Added NumberOfEmbeddings to ProjectBrief model - Created UserBrief model with counts (projects, definitions, instances) and updated GetUsersResponse to use it - Added NumberOfInstances to DefinitionBrief model - Added NumberOfProjects and NumberOfSharedUsers to InstanceBrief model - Updated handlers to populate counts in list responses Co-authored-by: awagner-mainz <2088443+awagner-mainz@users.noreply.github.com>
- Updated user tests to expect UserBrief with counts instead of just handles - Updated project tests to expect ProjectBrief with number_of_embeddings - Updated instance tests to expect InstanceBrief with number_of_projects and number_of_shared_users - Updated pagination tests to handle new UserBrief response structure - Updated public access tests with new InstanceBrief fields Co-authored-by: awagner-mainz <2088443+awagner-mainz@users.noreply.github.com>
The API returns the user list as a direct array, not wrapped in an object. Updated the pagination test to unmarshal correctly. Co-authored-by: awagner-mainz <2088443+awagner-mainz@users.noreply.github.com>
Created GetAllUsersWithCounts query that retrieves all user information with counts in a single efficient query using LEFT JOINs, eliminating the N+1 database query issue. Co-authored-by: awagner-mainz <2088443+awagner-mainz@users.noreply.github.com>

List endpoints returned minimal metadata without counts of related entities. Users needed multiple API calls to get basic relationship information (e.g., how many embeddings in a project, how many projects a user owns).
Changes
Database queries (5 new)
CountProjectsByUser,CountDefinitionsByUser,CountInstancesByDefinitionCountProjectsUsingInstance,CountSharedUsersForInstanceGetAllUsersWithCounts- optimized with LEFT JOINs, no N+1 queriesModels - added count fields:
ProjectBrief:number_of_embeddingsUserBrief:number_of_projects,number_of_definitions,number_of_instances(new model, replaces[]string)DefinitionBrief:number_of_instancesInstanceBrief:number_of_projects,number_of_shared_usersHandlers - populate counts in all list responses
Example

Notes
Minor N+1 query patterns remain in projects/definitions/instances list endpoints but are acceptable given typical result set sizes. Users endpoint is fully optimized with single-query approach.
