One aggregate per table, read-only. `messages` counts both roles. `calls` and `callMinutes` count completed calls only. `photosSolved` counts the distinct images the student attached to their own chat messages: Lala reads every such photo, but nothing records whether it held a question or whether the question was solved, so this is "photos sent", not a verdict. Photos on check-ins and uploads never attached to a message do not count. `firstMessageAt` is an instant. `firstDenemeAt` is the date the earliest paper was sat and `firstStudyDate` the first plan date with a done block, both local Istanbul dates. ## OpenAPI ````yaml /api-reference/openapi.json get /api/journey/together openapi: 3.1.0 info: title: Lala Client API description: >- The HTTP API behind Lala, the AI study companion for Turkish YKS and LGS students.
