PROJECT CHECKPOINT

Turn prisma orm into evidence

Replace the in-memory CourseFlow repository with PostgreSQL and Prisma.

  • Write acceptance criteria for models before implementation.
  • Keep the change small enough that a reviewer can connect it to the intended behavior.
  • Use the most direct check available for relations and save the result.
  • Record one decision you would keep and one you would revisit after feedback.
