The scenario
Fix sparse preference updates so false, midnight, and an explicit clear reach the notification desk.
A failure to reason about
Use a small apis scenario to compare the current behavior with the intended service behavior.
Illustrative context for the topic. The exercise’s full requirements arrive in the workspace.
Questions to bring to your review
- Which caller makes the reported behavior visible?
- What focused regression would distinguish the current behavior from the requirement?
- What existing behavior must remain intact after the change?
Skills you will practice
- Partial update semantics
- API contracts
- Presence versus value
- Regression testing
Read the existing code, reproduce the reported behavior, review proposed changes, and verify your final implementation. You can use AI assistance while staying responsible for the result.
