Code Review
This pull request removes the ".notNull()" constraint from the "upper_bound_idx" column in the "runs" database schema. The reviewer recommends keeping the constraint to prevent data integrity issues and maintain type safety, noting that the service layer already handles optional inputs appropriately.

Description
Removing the .notNull() constraint from upper_bound_idx introduces potential data integrity issues and type safety concerns across the codebase.
Why this is an issue:
- Data Integrity: Every run should have a valid upper bound (defaulting to
length - 1). Removing.notNull()allows runs to be persisted with anullupper bound, which violates the core business logic. - Type Safety: This change alters the inferred TypeScript type of
Run["upper_bound_idx"]fromnumbertonumber | null. Any existing frontend or backend code (such asresolveTrimBoundsor graphing components) that expects anumberwill now need to handlenull, increasing the risk of runtime errors or requiring widespread null-coalescing checks. - Redundancy: The service layer (
runs.service.ts) already gracefully handles optional inputs by resolvingupper_bound_idxtoMath.max(data.length - 1, 0)if not provided during creation or updates. Therefore, making the database column nullable is not required to support optional inputs at the API level.
Recommendation
Keep the .notNull() constraint to ensure database integrity and maintain strict type safety.
