Dataset Mutations

Rule

Always use functions in this directory. Never use direct Prisma calls.

Why

These functions handle:

1. Name validation - Dataset names validated for folder structure (/ separator, no leading/trailing slashes, no //)
2. Upsert logic - Correct handling of unique constraint on (projectId, name)
3. Null handling - Proper undefined vs null semantics for optional fields

Functions

• upsertDataset() - Create or update by name
• updateDataset() - Update by ID
