Theme Similarity: Keep Every Qualifying Match

Repair set-based similarity, then screen theme records without losing matches or rounding decisions.

The scenario

Repair set-based similarity, then screen theme records without losing matches or rounding decisions.

A failure to reason about

Use a small data integrity and testing scenario to compare current behavior with the requirement.

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

  • Set semantics
  • Similarity measures
  • Exact comparisons
  • 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.
